WTDXA30SJTB

Overview

The WTDXA30SJTB is a rectangular MIL-DTL-55302 series connector manufactured by Molex / AirBorn. It is a receptacle featuring 30 positions arranged in two rows with a 2.54 mm pitch. The component utilizes gold-plated copper alloy socket contacts and a Polyphenylene Sulfide (PPS) housing. Designed for cable mounting, it employs a crimp termination method suitable for 22 AWG wire. Electrical ratings include a current capacity of 5 A and a voltage rating of 1 kV, with an insulation resistance of 5 GOhms. The operating temperature range spans from -65 C to +125 C.

Feature Summary

• Compliant with MIL-DTL-55302 military specifications for rugged performance
• Features removable crimp contacts for simplified assembly and maintenance
• Constructed with high-temperature resistant Polyphenylene Sulfide housing

Applications

• Aviation systems interconnects
• Military electronic equipment
• Ruggedized industrial control panels

Procurement Notes

Verify the specific suffix codes against the official manufacturer datasheet to ensure correct contact type and orientation. Confirm RoHS compliance status as it may vary by production batch. Check for availability constraints or long lead times typical of specialized military-grade components. Ensure mating connectors share identical pin counts and row configurations.

Selection Notes

Select this part for applications requiring reliable board-to-cable connections under harsh environmental conditions. The 30-position count supports moderate signal density needs. Verify that the crimp tooling matches the specified 22 AWG wire gauge requirements. Consider the straight mounting angle for space-constrained chassis layouts.

Part Context

This component belongs to the AirBorn W Series, a line of high-reliability rectangular connectors designed for demanding environments. The series offers various position counts and termination styles to accommodate diverse system architectures while maintaining strict adherence to military standards for durability and electrical performance.

Replacement Considerations

Compatible substitutes within the same family include WTDXA20SAJTB and WTDXA26SAJTA, which share similar construction but differ in position count. Ensure any replacement maintains the 2-row configuration and crimp termination style.
