WTB26PR7SY

Overview

The WTB26PR7SY is a rectangular MIL-Spec connector from the AirBorn W Series, manufactured by Molex. It is a straight receptacle designed for board mount applications with 26 positions arranged in two rows. The component utilizes through-hole termination and features gold-plated copper alloy socket contacts. Constructed with a Polyphenylene Sulfide (PPS) housing, it operates within a temperature range of -65°C to +125°C. Electrical specifications include a 5 A current rating, 1 kV voltage rating, and 5 GOhms insulation resistance at a 2.54 mm pitch.

Feature Summary

• Compliant with MIL-DTL-55302 standards for military-grade reliability
• Utilizes gold-plated copper alloy contacts for corrosion resistance
• Features durable Polyphenylene Sulfide (PPS) insulating material

Applications

• Military avionics systems
• Ruggedized electronic enclosures
• High-reliability industrial control boards

Procurement Notes

Verify the specific suffix against official datasheets to confirm orientation and contact configuration. Ensure compatibility with mating plugs regarding MIL-DTL-55302 standards. Confirm RoHS compliance status via manufacturer certificates before integration into regulated assemblies.

Selection Notes

Select this part for high-density board-to-board connections requiring strict environmental resilience. The straight orientation suits vertical PCB mounting. Verify that the 2.54 mm pitch aligns with existing layout constraints and that the 26-position count meets circuit requirements without excessive unused space.

Part Context

This component belongs to the AirBorn W Series, a line of rectangular connectors engineered for mission-critical environments. The series emphasizes high density and reliability, often serving as replacements for legacy MIL-C-26482 or MIL-DTL-55302 designs in modern aerospace and defense electronics.

Replacement Considerations

Cross-reference with M55302/58-B26X for equivalent military specification compliance. Verify mechanical footprint and pinout alignment when substituting with other W Series variants.
