22-27-2061 パラメータおよび性能：米国における調達の洞察
Analysis of distributor listings, datasheet excerpts and procurement lead‑time trends shows this family remains a go‑to 2.54 mm (0.100") wire‑to‑board header for low‑power signal applications in US electronics manufacturing. The following guide distills those data points into practical specs, performance indicators and sourcing strategies focused on risk, compliance and cost‑to‑delivery tradeoffs for buyers and engineering teams.
Why the 22-27-2061 still matters in US designs (Background)
Market context & common applications
Point: Six‑position, 2.54 mm single‑row through‑hole headers continue to appear across consumer boards, industrial controls and legacy product servicing.
Evidence: many BOMs retain mixed new/legacy modules that require standard pitch headers.
Explanation: the 2.54mm pitch and 6‑position form factor provide predictable mating and hand‑assembly convenience, making the part a default for retrofit, serviceable connectors and low‑volume production where automated SMT isn’t justified.
Lifecycle & obsolescence signals to watch
Point: Part longevity is inferred from catalogue persistence and cross‑references.
Evidence: stable listing presence, multiple distributor entries and repeated replacement family mentions suggest longevity.
Explanation: engineering teams should monitor lifecycle codes, minimum order quantities and EOL notices; set triggers for redesign or qualified alternates when lead times exceed planned buffer or MOQ jumps unexpectedly.
22-27-2061 specs at a glance (Data / Specs)
Key mechanical & electrical specifications
Point: Datasheet baselines frame acceptance criteria.
Evidence: pitch 2.54 mm (0.100"), 6 positions, single‑row, vertical through‑hole mounting; typical current rating around 2–4 A depending on plating and temperature; common plating tin; UL‑rated insulators with V‑0 flammability.
Explanation: confirm pin length, tail length, plating and PCB thickness when writing RFQs; these drive solderability and current capability in application.
| Parameter | Typical Value | Notes |
|---|---|---|
| Pitch | 2.54 mm (0.100") | Standard wire‑to‑board pitch |
| Positions | 6 | Single row |
| Mount | Through‑hole, vertical | Solder tail length varies by variant |
| Current rating | ~2–4 A | Depends on contact area and plating |
| Plating | Tin (typ.) | Gold optional for low resistance/long life |
| Insulator | UL 94 V‑0 (typ.) | Confirm in datasheet |
Footprint, mating and assembly notes
Point: PCB footprint and assembly method affect yield.
Evidence: recommended solder fillet, hole tolerance and mechanical allowances appear on drawings.
Explanation: use datasheet dimensional drawings to confirm pad diameter, hole plating spec and keep‑out areas; specify wave or selective soldering guidance for through‑hole, and note if friction locks or polarizing keys are required for keyed mating or vibration resistance.
Performance & reliability: real-world indicators (Data analysis)
Electrical performance & derating factors
Point: Specified current ratings must be derated for temperature and contact resistance.
Evidence: contact resistance, insertion/withdrawal cycles and operating temperature define usable limits.
Explanation: require test metrics in validation (e.g., initial contact resistance ≤20 mΩ, >100 insertion cycles, thermal derating curves) and include acceptance criteria in QA to avoid field failures from overloaded signal pins.
Environmental and mechanical reliability
Point: Vibration, shock and humidity drive alternate selection or added controls.
Evidence: many field returns correlate to high‑vibration environments absent retention features.
Explanation: cite cycle counts, vibration profiles and salt spray requirements in RFQs; for high vibration, prefer variants with retention features, longer mating engagement or options with higher plating robustness.
Sourcing & procurement considerations for US buyers (Method / Sourcing)
Supply chain risk, lead times & cost tradeoffs
Point: Lead time and MOQ fluctuations are primary procurement risks.
Evidence: pricing varies with plating, pin length and packaging; long lead times indicate allocation risk.
Explanation: evaluate lead times weekly, plan safety stock based on burn rate, consider distribute buys and multiple qualified sources, and balance cost vs resilience by specifying acceptable alternates and packaging (tape & reel vs bulk) to reduce per‑piece cost.
Compliance, traceability & procurement docs
Point: Proper paperwork reduces compliance and counterfeit risk.
Evidence: procurement teams typically require RoHS/REACH declarations, material certifications and batch traceability.
Explanation: include certificate of conformity, lot traceability, and anti‑counterfeit clauses in contracts; request first‑article inspection samples and batch certificates for any long‑lead buys.
Compatibility, cross-references & alternatives (Case / Alternatives)
Cross-referencing tactics without brand names
Point: Dimensional verification is the primary cross‑reference method.
Evidence: mating relies on pitch, pin shape and polarization rather than vendor code.
Explanation: validate alternates by comparing mechanical drawings: pitch, pin tail shape, plating spec and polarizing features; prepare an engineering checklist for sign‑off that includes mechanical fit, electrical rating and solderability.
When to select a modern alternative
Point: Replace when assembly automation, density or reliability demands change.
Evidence: surface‑mount and higher‑current options reduce manual work and improve density.
Explanation: prioritize parameters in this order—pitch/compatibility, current rating, mounting style (SMD vs through‑hole), retention/locking features, and supply resilience—when deciding to move away from the legacy header form.
Buyer checklist & next steps (Actionable)
Quick procurement checklist (ready-to-use)
- Exact part number: 22-27-2061; reference drawing and revision level.
- Required specs: pitch 2.54 mm, 6 positions, single row, plating, tail length, PCB hole size.
- Certifications: RoHS/REACH declaration, UL insulator rating, material/certificates of conformity.
- Acceptable alternates: dimensional drawing attached, electrical rating match, solderability equivalence.
- Logistics: lead time expectation, MOQ, packaging type, inspection sample request.
Implementation steps for engineering & procurement teams
- Confirm footprint and mechanical spec match the board drawing.
- Request sample and full datasheet for review.
- Run validation tests (electrical, mechanical, environmental).
- Lock suppliers with traceability agreements and inspection plan.
- Monitor burn rates and reorder thresholds to prevent allocation.
Summary
Central takeaway: this header remains a practical, well‑understood 2.54 mm option for many US designs, combining serviceability and predictable mating. Successful sourcing pairs datasheet‑led specification checks with proactive supply‑chain practices—lead‑time monitoring, compliance documentation and pre‑qualified alternates—to balance cost, risk and delivery.
Key summary
- Confirm mechanical specs and PCB footprint against the datasheet before RFQ to ensure mating and solderability match the design.
- Mitigate supply risk via safety stock, multiple qualified sources and clear MOQ/packaging requirements in purchase orders.
- Require traceability and material certifications in procurement documents to address compliance and counterfeit risk.
Frequently Asked Questions
How should procurement validate 22-27-2061 electrical specs?
Procurement should request the full datasheet, specify required current rating and plating in the PO, and require a sample for engineering validation. Include acceptance criteria for contact resistance, insulation resistance and thermal derating curves, and mandate first‑article inspection where lead times or quality risks are elevated.
What footprint checks should engineering perform for a 2.54mm header?
Engineering must verify pad diameter, hole size/tolerance, recommended solder fillet, and keep‑out areas using the dimensional drawing. Confirm pin tail length and PCB thickness are compatible with wave or selective soldering processes, and ensure polarizing features align with mating components.
Which procurement clauses reduce counterfeit and compliance risk?
Include clauses requiring RoHS/REACH declarations, material certificates of conformity, lot traceability, and rights to source inspection samples. Add anti‑counterfeit language that mandates traceable supply chains and the ability to audit supplier quality records for long‑lead or high‑volume buys.
