WTB24SACSY

Overview

The AirBorn WTB24SACSY is a rectangular MIL-DTL-55302 series connector featuring 24 positions in a 2-row configuration. It utilizes a 2.54 mm pitch with gold-plated copper alloy socket contacts and solder cup termination. Designed for board mount installation, the housing is constructed from polyphenylene sulfide (PPS). The component operates within a temperature range of -65°C to +125°C, supports a current rating of 5 A, and withstands up to 1 kV voltage. Insulation resistance is rated at 5 GOhms, suitable for demanding military and industrial environments.

Feature Summary

• Compliant with MIL-DTL-55302 military specifications for rugged reliability
• Gold-plated contacts ensure stable signal transmission in harsh conditions
• Polyphenylene sulfide housing provides high thermal stability and chemical resistance

Applications

• Military avionics systems requiring certified interconnect solutions
• Industrial control panels operating under extreme temperature variations
• Ruggedized electronic equipment needing high-density I/O connections

Procurement Notes

Verify the specific suffix codes against official Molex/AirBorn documentation to confirm exact contact plating thickness and housing material variants. Ensure compatibility with mating plugs regarding keying options and shell size. Cross-reference the MIL-DTL-55302 designation with current procurement standards to avoid obsolete stock or non-conforming replacements during acquisition.

Selection Notes

Select this receptacle when a straight, board-mount solution with solder cup termination is required for 22 AWG wiring. Confirm that the 2.54 mm pitch aligns with the PCB layout and that the 24-position count matches the circuit design. Validate that the PPS housing material meets the environmental exposure requirements of the target application before finalizing the bill of materials.

Part Context

This component belongs to the AirBorn W Series, a line of high-performance rectangular connectors designed for severe environment applications. The series emphasizes durability and consistent electrical performance across military and aerospace sectors. The WTB24SACSY specifically addresses needs for compact, high-density interconnects with robust mechanical locking features inherent to the MIL-DTL-55302 standard.

Replacement Considerations

The part number alias M55302/58-A24X indicates a direct cross-reference to the MIL-DTL-55302 specification. Verify that any substitute maintains the identical 24-position, 2-row configuration and solder cup termination style to ensure physical and electrical interchangeability without redesign.
