WGA122PR11J342

Overview

The WGA122PR11J342 is a rectangular MIL-Spec connector from the AirBorn W Series, manufactured by Molex. It functions as a board mount plug with 122 positions arranged in three rows. The component utilizes through-hole termination and features male pin contacts with gold plating on copper alloy substrates. Designed for right-angle installation, it operates within a temperature range of -65°C to +125°C. Key electrical specifications include a 5 A current rating, 1 kV voltage rating, and 5 GOhms insulation resistance. The housing is constructed from Polyphenylene Sulfide (PPS) with a 2.54 mm pitch.

Feature Summary

• Compliant with MIL-DTL-55302 standards for military-grade reliability
• Right-angle board mount configuration for space-constrained PCB layouts
• Gold-plated copper alloy contacts ensure stable signal transmission
• Polyphenylene Sulfide (PPS) housing provides thermal stability

Applications

• Military avionics systems requiring rugged interconnects
• Aerospace electronic control units
• High-density communication equipment backplanes

Procurement Notes

Verify the specific suffix J342 against official Molex/AirBorn documentation to confirm tail length and jackset configuration. Ensure compatibility with corresponding receptacles such as WG80SOR11JL342 or similar W-Series counterparts. Confirm RoHS compliance status via the manufacturer's certificate before integration into regulated assemblies.

Selection Notes

Select this part when a high-density, right-angle plug is required for MIL-DTL-55302 applications. The 122-position count and 3-row layout suit complex signal routing needs. Verify that the through-hole termination method aligns with the target PCB fabrication capabilities and that the operating temperature range meets environmental requirements.

Part Context

This component belongs to the AirBorn W Series, a line of rectangular connectors designed for harsh environments. The series offers various configurations including straight and right-angle options with different row counts. The WGA122PR11J342 specifically addresses high-pin-count applications requiring robust mechanical retention and reliable electrical performance under extreme conditions.

Replacement Considerations

Compatible mating connectors include WG80SOR11JL342 and other W-Series receptacles with matching 2.54 mm pitch and 122-position layouts. Ensure identical contact gender and termination style for proper assembly.
