IPL1-116-01-L-D-RA-K: Detailed Specs & Performance Ratings
The IPL1-116-01-L-D-RA-K is a precision-engineered 2.54 mm (0.100") pitch connector designed for rugged industrial environments. With a current rating of approximately 3.8 A and a UL94 V-0 rated molded housing, this component is a cornerstone for board-to-wire power distribution where thermal headroom and safety compliance are non-negotiable.
1 — Product Overview & Intended Use
The IPL1-116-01-L-D-RA-K features a right-angle through-hole configuration, providing a low-profile interface for daughterboards and modular interconnects. Its shrouded design prevents misalignment and protects pins from mechanical damage during assembly.
- Physical Form Factor: Right-angle, dual-row, shrouded header.
- Pitch: Standard 2.54 mm for high compatibility.
- Applications: Industrial control panels, power busses, and instrumentation modules.
2 — Key Electrical Specifications & Performance Ratings
| Parameter | Datasheet Value | Design Note |
|---|---|---|
| Current Rating | ~3.8 A per pin | Derate by 20% for ambient > 25°C |
| Voltage Rating | 675 VAC / 950 VDC | Check creepage for high-altitude |
| Insulation Resistance | ≥ 10⁹ Ω | Guaranteed by UL94 V-0 polymer |
| Contact Resistance | < 10 mΩ | Stable over 1,000+ mating cycles |
3 — Thermal & Reliability Behavior
Thermal management is critical for the IPL1-116-01-L-D-RA-K. While the housing handles high temperatures, the contact metallurgy softens beyond recommended thresholds. Derating is mandatory: a 3.8 A load at 25°C should be reduced to approximately 2.8 A at 70°C to maintain long-term reliability.
4 — Mechanical Specs & PCB Integration
For successful integration of this 2.54mm header, designers must account for the right-angle solder tail geometry. Ensure the PCB footprint includes sufficient annular rings for the through-hole pins and clear silkscreen markings for the shroud orientation.
5 — Comparative Performance
| Feature | IPL1 Series | Standard 2.54mm Header |
|---|---|---|
| Housing Safety | UL94 V-0 (Self-extinguish) | Variable / HB Rated |
| Pin Protection | Fully Shrouded | Exposed / Unshrouded |
| Max Current | High (3.8A) | Standard (1-2A) |
6 — Buyer's Checklist & Summary
- Verify Plating: Confirm 'L' (10µ" Gold) vs 'F' (Gold Flash) options.
- Process Compatibility: Ensure wave solder profiles match the right-angle thermal mass.
- Mechanical Support: Consider adhesive or brackets for high-vibration environments.
FAQ
What are the IPL1-116-01-L-D-RA-K electrical limitations I should check?
Check datasheet-rated per-pin current (~3.8A), rated voltage, dielectric strength, and insulation resistance. Apply derating for elevated ambient temperatures and verify per-pin versus collective current limits in multi-pin power use.
How should I validate the 2.54mm header footprint for PCB assembly?
Use the manufacturer land pattern as the baseline, confirm drill sizes and tolerances, ensure solder mask openings are correct, and allow mechanical keepouts for the shroud. Run a fabrication test panel to validate solder fillets.
Which tests prove long-term reliability for right-angle 2.54mm headers?
Run contact-resistance vs cycle tests, thermal cycling, steady-state current with temperature logging, vibration/shock, and corrosion tests. Set acceptance criteria based on ΔR thresholds (typically <10%).
What is the significance of the UL94 V-0 rating in this connector?
The UL94 V-0 rating indicates that the housing material stops burning within 10 seconds on a vertical specimen and does not allow flaming drips. This is a critical safety requirement for industrial electronics and power distribution modules.
