• Features gold-plated contacts for reliable signal transmission
• Utilizes durable polyphenylene sulfide housing material

Applications

• Military electronic systems
• Aviation instrumentation
• Ruggedized industrial control panels

Procurement Notes

Verify the specific suffix '-27' against official Molex/AirBorn documentation to confirm exact plating thickness or contact configuration variations. Ensure compatibility with mating receptacles regarding row count and pitch. Confirm RoHS compliance status via current certificates as regulatory requirements may evolve. Cross-reference datasheet revisions to validate terminal type and mounting style consistency.

Selection Notes

Select this model when high-density interconnectivity is required in constrained spaces. The 2.54 mm pitch allows for standard PCB layouts while maintaining robust mechanical integrity. Consider the through-hole termination method for superior solder joint strength compared to surface mount alternatives. Evaluate the 122-position capacity against circuit density requirements before finalizing the design.

Part Context

This component belongs to the AirBorn W Series, a line of rectangular connectors designed for harsh environments. The series emphasizes durability and reliability for defense and aerospace sectors. The WGA prefix typically denotes a plug configuration with specific mounting characteristics. This part represents a high-pin-count solution within the broader family of MIL-spec interconnects.

Replacement Considerations

Compatible mating parts must share the same 3-row, 122-position layout and 2.54 mm pitch. Verify that alternative sockets offer matching gold plating and PPS housing materials. Ensure any substitute adheres to MIL-DTL-55302 standards for interchangeability.
