WTB90SAW24SY

Overview

The AirBorn WTB90SAW24SY is a rectangular MIL-DTL-55302 series connector designed for board mount applications. It features a straight receptacle configuration with 90 positions arranged in two rows. The component utilizes through-hole termination and socket contacts with gold plating on copper alloy substrates. Constructed with a polyphenylene sulfide (PPS) housing, it supports a 2.54 mm pitch and operates within a temperature range of -65°C to +125°C. Rated for 5 A current and 1 kV voltage, it ensures reliable signal transmission in demanding environments.

Feature Summary

• Compliant with MIL-DTL-55302 military specifications for rugged performance
• Features gold-plated copper alloy socket contacts for corrosion resistance
• Utilizes durable polyphenylene sulfide housing material
• Supports high-density interconnects via dual-row straight mounting

Applications

• Military avionics systems requiring certified interconnects
• Ruggedized electronic equipment enclosures
• High-reliability industrial control panels
• Defense communication hardware assemblies

Procurement Notes

Verify the specific suffix 'AW' against official Molex/AirBorn documentation to confirm wire wrap termination compatibility, as standard 'AD' variants typically use solder tail. Confirm RoHS compliance status directly with the manufacturer. Ensure the ordering part number matches the exact contact type and mounting style required for your PCB layout design.

Selection Notes

Select this component when a high-pin-count, dual-row MIL-spec receptacle is required for vertical board mounting. Compare against similar W-series parts like WTB90SAD9SY if solder tail termination is preferred over wire wrap. Verify that the 2.54 mm pitch aligns with your circuit board trace spacing requirements and that the 90-position density fits within your available panel space constraints.

Part Context

This part belongs to the AirBorn W Series, a family of rectangular connectors known for meeting stringent military standards. The WTB prefix indicates a straight receptacle variant. These connectors are engineered for harsh environments, offering robust mechanical stability and electrical performance suitable for critical defense and aerospace infrastructure deployments globally.

Replacement Considerations

M55302/60-B90X is a confirmed public substitute part number alias for this component. Verify pinout orientation and physical dimensions before substitution.
