Connector overview — what the MPN 22-05-7045 is and where it’s used
Form factor & core identifiers
The 22-05-7045 is a single-row, 4-position PCB header with a 2.50 mm pitch and through-hole tails arranged for right-angle mounting when used in right-angle variants; contact gender is pin (male).
- Pitch: 2.50 mm center-to-center spacing.
- Positions: 4-pin single row configuration.
- Mounting: Through-hole tail for standard 1.6 mm PCBs.
- Plating: Tin finish as standard specification.
Typical application cases & system-level fit
Common use cases include wire-to-board signal headers, internal harness connections in small consumer electronics, and control-board jumpers in industrial equipment where low current and compact spacing are priorities. Typical mating is with a compatible 4-position female housing or board-to-board receptacle; environments are generally indoor, low-power, and low-vibration unless reinforced by mechanical retention features. Long-tail search phrase: 2.5mm 4-position right-angle header for signal connections.
Datasheet breakdown — complete electrical & mechanical specs
Mechanical & dimensional specs
Critical mechanical details pulled from the datasheet and recommended for CAD/footprint transfer include pitch (2.50 mm), positions (4), row count (1), overall board footprint length, pin diameter, and through-hole drill size. Below is a compact spec table engineers should import into their library.
| Parameter | Value |
|---|---|
| Pitch | 2.50 mm |
| Positions | 4 |
| Row count | 1 |
| Mounting | Through-hole (right-angle variant available) |
| Plating | Tin finish (standard) |
| Recommended drill | 0.9–1.0 mm (verify part drawing) |
Electrical ratings & performance metrics
Typical values to plan for design margins: rated current consistent with signal headers (mid-range amperage), contact resistance in the low milliohm range, and insulation resistance in the megaohm range. Translate these to safety margins by derating current by 25–50% for continuous operation.
PCB footprint, assembly & reliability considerations
Footprint & Manufacturing
Accurate pad-to-pad spacing at 2.50 mm and plated-through hole size per the datasheet are mandatory. For through-hole tails, expect a fillet height indicating good solder wetting. Wave solder practices should include fixtures to maintain right-angle orientation during processing.
Mechanical Durability
Typical signal headers list mating cycles in the low hundreds to thousands. For harsh environments, add retention features like board standoffs or adhesive at the header base. Use thermal cycling test results as a baseline for stress relief design.
Comparing alternatives & trade-offs
When comparing the 22-05-7045 to alternatives, consider the subtle differences that impact long-term reliability and board compatibility.
| Feature | MPN 22-05-7045 | Typical 2.54mm Alternative |
|---|---|---|
| Pitch | 2.50 mm (Metric) | 2.54 mm (Imperial) |
| Plating | Standard Tin | Optional Gold Flash |
| Best Use Case | Density-constrained | Legacy/Standard Pitch |
Practical engineer checklist
Pre-sourcing Design
- Verify footprint against official PDF drawing.
- Confirm plating compatibility with solder process.
- Ensure temp range matches environment.
- Check mating part polarity and keying.
Validation Plan
- Perform mechanical fit/mate check.
- Measure continuity and contact resistance.
- Conduct thermal soak at max operating temp.
- Log insertion/removal cycle failure points.
Summary
The MPN 22-05-7045 is a compact 2.50 mm pitch, 4-position through-hole header whose datasheet and specs make it suitable for low- to mid-current signal connections where board density and a small footprint matter. Key design cautions include verifying hole size and pad pattern, accounting for solder process fixturing, and derating electrical limits for continuous operation.
Key summary points:
- • 2.50 mm pitch requires precise CAD geometry to avoid drill/pad mismatch.
- • Derate electrical ratings by 25–50% for thermal and safety margins.
- • Use wave soldering fixtures for right-angle variants to ensure joint reliability.
