WTBV44PD9SY

Overview

The WTBV44PD9SY is a rectangular MIL-DTL-55302 qualified connector from the AirBorn W Series, manufactured by Molex. It is a straight plug designed for board mount installation with through-hole termination. The component features 44 positions arranged in two rows with a 2.54 mm pitch. Male pin contacts are gold-plated copper alloy, rated for 5 A current and 1 kV voltage. The housing is constructed from Polyphenylene Sulfide (PPS), supporting an operating temperature range of -65 C to +125 C and providing 5 GOhms insulation resistance.

Feature Summary

• Compliant with MIL-DTL-55302 military specifications for rugged reliability
• Utilizes gold-plated copper alloy male pin contacts for stable signal transmission
• Constructed with Polyphenylene Sulfide housing for thermal stability
• Features a two-row straight configuration for dense board mounting

Applications

• Military avionics systems requiring MIL-DTL-55302 compliance
• Ruggedized electronic equipment operating in extreme temperatures
• High-density board-to-board interconnects in defense applications

Procurement Notes

Verify the specific suffix PD9SY against official Molex/AirBorn documentation to confirm contact type, plating, and orientation. Ensure compatibility with mating receptacles within the same series. Confirm RoHS status and material declarations via the manufacturer datasheet before integration into regulated supply chains.

Selection Notes

Select this part for applications requiring a straight, board-mount plug with 44 positions. Verify that the 2.54 mm pitch and 5 A rating meet circuit requirements. Ensure the mating counterpart is a compatible W Series receptacle. Consider the PPS housing material for high-temperature environments up to 125 C.

Part Context

This component belongs to the AirBorn W Series, a line of rectangular connectors known for durability in harsh environments. The series offers various row options and contact counts, standardized under MIL-DTL-55302. The WTBV44PD9SY specifically addresses needs for high-pin-count, straight-mount interconnects in military and aerospace sectors.

Replacement Considerations

Cross-reference with equivalent MIL-DTL-55302 connectors from other manufacturers if sourcing constraints exist. Verify mechanical dimensions, pinout, and electrical ratings match exactly. No direct substitute part numbers are confirmed in the provided data.
