WTBT54SARCJTB

Overview

The WTBT54SARCJTB is a rectangular MIL-spec connector from the AirBorn WTB series, manufactured by Molex. It functions as a right-angle receptacle with 54 positions arranged in two rows. The component utilizes solder termination for board mounting and features gold-plated female contacts made of copper alloy. Constructed with a polyphenylene sulfide (PPS) shell, it supports a current rating of 5 A per contact. The unit operates within a temperature range of -65°C to +125°C and maintains an insulation resistance of 5000 MOhms.

Feature Summary

• Right-angle receptacle design for efficient panel or board space utilization
• Gold-plated female contacts ensure reliable signal transmission and corrosion resistance
• Polyphenylene sulfide housing provides high thermal stability and mechanical durability

Applications

• Military avionics systems requiring rugged interconnects
• Ground-based defense communication equipment
• Aerospace instrumentation panels

Procurement Notes

Verify the specific suffix codes against the manufacturer's latest datasheet to confirm orientation and contact configuration. Ensure compatibility with mating plugs regarding shell size and pinout. Check for RoHS compliance status if required by project specifications. Confirm availability through authorized distributors as lead times may vary for military-grade components.

Selection Notes

Select this part for applications requiring a compact, right-angle connection solution with high pin density. The 54-position layout suits complex signal routing needs. Ensure the mating environment accommodates the specified operating temperature range. Verify that the board layout supports the right-angle footprint and solder termination method.

Part Context

This component belongs to the AirBorn WTB series, designed for harsh environments. The series offers various configurations including straight and right-angle options. It is widely used in aerospace and defense sectors where reliability under vibration and extreme temperatures is critical. The brand is now integrated under Molex.

Replacement Considerations

Check for direct substitutes within the same WTB series with different suffixes for variant orientations. Cross-reference with other MIL-DTL-38999 compatible connectors if form-factor changes are permissible. Verify pin-to-pin compatibility before substitution.
