WGA122SAD11SY-27

Overview

The WGA122SAD11SY-27 is a rectangular MIL-Spec receptacle from the AirBorn W Series, manufactured by Molex. It features 122 positions arranged in three rows with a 2.54 mm pitch. Designed for board mounting, it utilizes through-hole termination and gold-plated copper alloy female contacts. The housing is constructed from Polyphenylene Sulfide (PPS), supporting a voltage rating of 1 kV and current capacity of 5 A. Operating temperatures range from -65 C to +125 C, with an insulation resistance of 5 GOhms.

Feature Summary

• Compliant with MIL-DTL-55302 military specifications for rugged reliability
• Features polarization mechanism identified by suffix -27 for secure mating alignment
• Utilizes gold-plated contacts on a PPS insulator for high corrosion resistance
• Supports vertical board mounting with through-hole soldering

Applications

• Avionics control systems
• Spacecraft instrumentation
• Electronic warfare equipment

Procurement Notes

Verify the specific polarization code (-27) against design requirements to ensure correct mating orientation. Confirm RoHS compliance status via official documentation before integration. Validate that the 122-position configuration matches the PCB footprint exactly. Ensure the supplier provides traceability certificates required for military-grade components.

Selection Notes

Select this component when a high-density, three-row MIL-DTL-55302 receptacle is required. The -27 suffix indicates a specific polarization keying essential for preventing misalignment in critical assemblies. Compare against standard unpolarized variants if orientation locking is not necessary. Ensure the 2.54 mm pitch aligns with existing board layout constraints.

Part Context

This part belongs to the AirBorn W Series, a line of rectangular connectors designed for harsh environments. The series offers various row counts and polarization options to meet diverse military and aerospace interface needs. The WGA variant specifically denotes a three-row configuration within this standardized family.
