WTB26PR9SY-6

Overview

The WTB26PR9SY-6 is a rectangular MIL-DTL-55302 series connector manufactured by Molex / AirBorn. It is a board mount plug featuring 26 positions in a dual row configuration with a 2.54 mm pitch. The component utilizes through-hole termination and gold-plated copper alloy pin contacts. Rated for 5 A current and 1 kV voltage, it operates within a temperature range of -65 C to +125 C. The housing is constructed from Polyphenylene Sulfide (PPS). This specific variant includes polarization guide set 6 and mounting ears.

Feature Summary

• Includes integrated polarization guide set 6 for precise mating alignment
• Features mounting ears for secure mechanical attachment to the circuit board
• Utilizes gold-plated copper alloy pin contacts for reliable conductivity

Applications

• Military avionics control systems
• Spacecraft electronic interfaces
• Radar system interconnects

Procurement Notes

Verify the specific polarization guide set number matches the mating receptacle requirements. Confirm that the right-angle orientation and mounting ear specifications align with the PCB layout constraints. Ensure the through-hole tail length is compatible with the board thickness and soldering process capabilities.

Selection Notes

Select this part when a polarized, right-angle board mount plug is required for high-reliability applications. The inclusion of mounting ears provides additional stability compared to non-ear variants. Verify compatibility with the corresponding WTB26SAD9SY-6 or equivalent receptacle sharing the same polarization guide set.

Part Context

This component belongs to the AirBorn W Series, designed for mission-critical environments requiring high density and reliability. The series adheres strictly to MIL-C-55302 standards, ensuring performance in harsh conditions such as those found in aerospace and defense sectors.

Replacement Considerations

M55302/61B26X is the official military specification alias for this part number. When sourcing substitutes, ensure the replacement maintains the exact polarization guide set 6 designation to guarantee proper mechanical engagement.
