22232031 Connector Specs & Footprint: Complete Data Pack
Design teams waste cycles reconciling partial datasheet notes; this consolidated 22232031 connector data pack gives a single-source reference to remove ambiguity and accelerate DFM sign-off. The pack focuses on verified electrical, mechanical, and footprint guidance so engineers can avoid re-spins and speed production handoffs.
Quick Overview & Key Specs
At-a-glance Spec Summary
Point: A compact spec table lets layout and procurement teams confirm compatibility quickly. Evidence: The entries below represent conservative, industry-typical ratings for this header family and the associated PCB land pattern expectations. Explanation: Use the table as a starting validation; final acceptance must match the specific manufacturer datasheet used for the bought part.
| Attribute | Typical Value / Notes |
|---|---|
| Part number | 22232031 (family reference) |
| Positions | 3 (variants available) |
| Pitch | 2.54 mm / 0.100" |
| Mounting style | Through-hole (straight header) |
| Termination type | Solder tail |
| Rated current | 3 A per contact (typical) |
| Rated voltage | 250 VAC / DC (typical) |
| Contact material & plating | Bronze alloy; tin or selective gold plating options |
| Housing material & flammability | PBT or nylon; UL94 V-0 preferred |
| Operating temperature | -40 °C to +105 °C |
| Mating cycles | ~500 cycles (industry-typical) |
Typical Applications & Selection Rationale
Point: This header family suits signal headers, jumper arrays, and low-power IO where 2.54 mm pitch and robust mechanical retention are required. Evidence: Common uses include board-to-wire jumpers, sensor headers, and daughterboard interfaces. Explanation: Choose this connector over fine-pitch variants when assembly speed, through-hole strength, and easy hand-rework are priorities; select alternatives when board space or high-density routing demands micro-pitch solutions.
Electrical & Mechanical Data Deep-Dive
Electrical Specifications to Validate
Point: Validate contact resistance, insulation resistance, dielectric voltage, and current derating before committing to production. Evidence: Typical contact resistance target is under 20 mΩ initial; insulation resistance 1 GΩ minimum; dielectric withstanding often 500 VAC between adjacent circuits. Explanation: For power or mixed-signal use, derate current by ambient temperature and via copper area; confirm solder joint thermal limits and run signal integrity checks for high-speed lines adjacent to the header.
Mechanical & Environmental Specifications
Point: Mechanical durability and mounting support determine long-term reliability. Evidence: Typical mating cycles ~500, insertion/extraction forces per pin range from 0.5–3 N depending on contact design. Explanation: Specify PCB reinforcement (via thicker FR4 or local support), avoid routing critical traces under through-hole tails without thermal relief, and define vibration/shock tolerance in procurement notes to align with the assembly environment.
Performance Ratings (Typical)
PCB Footprint & Land Pattern
Recommended Footprint Dimensions & Drill/Pad Sizes
Point: A correct land pattern minimizes assembly rework and ensures solder fillet integrity. Evidence: For 2.54 mm pitch through-hole tails, recommended pad drill ~1.0 mm, annular ring ≥0.25 mm, pad length 1.6–2.0 mm, and pad width 1.0–1.5 mm; stencil apertures for solder-plated through-holes typically omitted for wave but defined for selective solder. Explanation: Use neutral CAD outputs (e.g., IPC-compliant XY CSV for pad arrays) and verify drill tolerance ±0.05 mm.
Layout Best Practices & Mechanical Keepouts
Point: Keep mechanical clearances and orientation marks to reduce assembly errors. Evidence: Place silkscreen orientation marker next to pin 1, define 1.5 mm keepout around header edges and add thermal reliefs for through-hole pads if wave soldering. Explanation: Reserve nearby PCB area for solder fillets, avoid SMD component placement directly adjacent on the solder side, and supply STEP/IGES 3D files for mechanical clearance checks.
Example PCB Integration & Common Pitfalls
Integration Walk-through
- • Place footprint with orientation marker
- • Route non-critical signals away from tails
- • Add mechanical support vias or glue pads
- • Validate DRC for drill-to-pad clearance
Troubleshooting Checklist
Avoid these frequent issues:
- ! Wrong drill size (too tight for plating)
- ! Omitted mechanical keepouts
- ! Incorrect solder mask expansion
- ! Mis-specified plating for environment
Pre-production Checklist & Deliverables

CAD Assets
Ensure the following are in your repo:
Summary
- ✓ Consolidated specs reduce ambiguity—confirm the 22232031 connector family ratings against your supplier datasheet before release; check current, voltage, and mating cycle limits against system needs.
- ✓ Follow the recommended land pattern and drill sizes; ensure annular rings and thermal reliefs are defined to prevent soldering or mechanical failures during assembly and wave processes.
- ✓ Use the pre-production checklist: footprint verification, 3D clearance checks, solderability and pull tests, and documented pass/fail tolerances to avoid PCB re-spins and speed production sign-off.
