WGA122SACJTB342

Overview

The WGA122SACJTB342 is a rectangular MIL Spec connector from the AirBorn W Series, manufactured by Molex. It features 122 positions arranged in three rows with a 2.54 mm pitch. Designed as a receptacle, it utilizes gold-plated copper alloy socket contacts and solder cup termination for PCB mounting. The housing is constructed from Polyphenylene Sulfide (PPS). Rated for 5 A current and 1 kV voltage, it operates within a temperature range of -65 C to +125 C.

Feature Summary

• High-density interconnect capability with 122 contact positions in a compact three-row configuration.
• Robust construction using Polyphenylene Sulfide housing and gold-plated copper alloy contacts for reliable signal transmission.
• Secure PCB mounting via solder cup termination style ensuring stable mechanical attachment.

Applications

• Military and aerospace electronic systems requiring high reliability.
• Industrial control panels needing dense I/O connections.
• Ruggedized communication equipment interfaces.

Procurement Notes

Verify the specific suffix JTB342 against official datasheets to confirm exact contact orientation and mounting variations. Ensure compatibility with mating plugs in the same W Series family. Confirm RoHS compliance status through manufacturer certificates prior to integration into regulated assemblies.

Selection Notes

Select this component when high pin count density is required in a straight receptacle form factor. Compare against WG92SACJTB or WGAV122PD9JTB-B82 if position counts or plug/receptacle roles differ. Validate that the 2.54 mm pitch matches the target PCB footprint design constraints.

Part Context

This part belongs to the AirBorn W Series, a line of rectangular connectors designed for demanding environments. The series offers various row configurations and contact densities. The WGA122SACJTB342 specifically addresses applications requiring substantial connectivity within a standardized military-specification envelope.

Replacement Considerations

Direct substitutes include other W Series receptacles with matching 122-position layouts. Verify equivalent electrical ratings and physical dimensions before cross-referencing with generic MIL-DTL-55302 equivalents.
