WG104PR9SY-8

Overview

The WG104PR9SY-8 is a rectangular MIL-DTL-55302 series connector manufactured by Molex / AirBorn. It is a right-angle plug with 104 positions arranged in three rows, utilizing gold-plated copper alloy pin contacts and through-hole termination for board mounting. The housing is constructed from Polyphenylene Sulfide (PPS). Electrical ratings include a current capacity of 5 A and a voltage rating of 1 kV, with an insulation resistance of 5 GOhms. The operating temperature range spans from -65 C to +125 C, featuring a 2.54 mm pitch and compatibility with 22 AWG wire.

Feature Summary

• Compliant with MIL-DTL-55302 military specifications for rugged performance
• Right-angle board mount configuration for space-constrained PCB layouts
• Gold-plated contacts ensure reliable signal transmission in harsh environments

Applications

• Avionics control systems
• Military communication equipment
• Radar and electronic warfare units

Procurement Notes

Verify the specific polarization guide set number associated with the suffix '-8' against the official datasheet before procurement. Confirm that the manufacturing origin aligns with required supply chain security protocols. Ensure the ordering quantity meets any minimum order requirements specified by the authorized distributor or manufacturer.

Selection Notes

Select this component when a high-density, right-angle interconnect solution is required for MIL-Spec applications. The 104-position count and 2.54 mm pitch suit complex circuit boards needing robust mechanical retention. Verify that the 5 A current rating per contact satisfies the system's power distribution requirements under maximum operating temperatures.

Part Context

This part belongs to the AirBorn W Series, designed for demanding defense and aerospace environments. The series offers various configurations including straight and right-angle plugs and receptacles. The WG104PR9SY-8 specifically provides a male pin interface with a defined polarization index to prevent mating errors in critical assemblies.

Replacement Considerations

Compatible counterparts within the same family include WG104PR9SY variants with different polarization indices. Cross-brand replacements must strictly adhere to MIL-DTL-55302 dimensions and electrical characteristics to ensure interchangeability without redesigning the host printed circuit board.
