WTA54SAD9JL

Overview

The WTA54SAD9JL is a rectangular MIL-Spec connector from the AirBorn W Series, manufactured by Molex. It is a receptacle featuring 54 positions arranged in two rows with socket contacts. The component utilizes through-hole termination for board mounting and operates at a straight angle. Constructed with a Polyphenylene Sulfide (PPS) housing and gold-plated copper alloy contacts, it supports a 2.54 mm pitch. Rated for 1 kV voltage and 5 A current, it functions within a temperature range of -65°C to +125°C and complies with MIL-DTL-55302 standards.

Feature Summary

• Complies with MIL-DTL-55302 military specifications for rugged reliability
• Features dual-row receptacle configuration with socket contacts
• Utilizes gold-plated copper alloy contacts for corrosion resistance
• Constructed with Polyphenylene Sulfide (PPS) insulating material

Applications

• Military avionics control systems
• Aerospace electronic interconnects
• Ruggedized board-to-board connections

Procurement Notes

Verify the specific revision level and RoHS compliance status directly with Molex or authorized distributors before procurement. Confirm that the 54-position variant matches the exact mechanical footprint requirements of the target PCB layout. Ensure mating connectors are selected from the compatible W Series plug lineup to guarantee proper pin-and-socket alignment and electrical continuity.

Selection Notes

Select this part when a high-density, two-row receptacle is required for MIL-DTL-55302 applications. The 54-position count necessitates careful PCB space allocation compared to lower-count variants like the WTA20 or WTA30. Verify that the through-hole soldering process accommodates the specific tail length and pitch dimensions defined in the official datasheet to ensure mechanical stability.

Part Context

This component belongs to the AirBorn W Series, a family of rectangular connectors designed for harsh environments. The series offers various position counts and contact types, all sharing common mechanical interfaces and material standards. The WTA54SAD9JL represents a high-density option within this lineup, providing robust connectivity for complex electronic assemblies requiring strict adherence to military performance criteria.
