WG104PR9SY342-3

Overview

The WG104PR9SY342-3 is a rectangular MIL-Spec connector from the AirBorn W Series, manufactured by Molex. It features 104 positions arranged in three rows with a 2.54 mm pitch. Designed as a right-angle plug with gold-plated copper alloy pins, it utilizes 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. Insulation resistance is specified at 5 GOhms. The component operates within a temperature range of -65 C to +125 C.

Feature Summary

• Complies with MIL-DTL-55302 military specifications for rugged performance
• Features right-angle board mount configuration for space-efficient design
• Utilizes gold-plated contacts on copper alloy substrates for conductivity
• Constructed with Polyphenylene Sulfide housing for thermal stability

Applications

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

Procurement Notes

Verify the specific suffix against official Molex documentation to ensure correct mating compatibility and pin assignment. Confirm that the right-angle orientation matches the PCB layout requirements. Check RoHS compliance status via the manufacturer's certificate. Ensure the through-hole termination method aligns with the assembly process capabilities. Validate the 104-position count against the system interface needs.

Selection Notes

Select this component when a high-density, MIL-specification interconnect is required for harsh environments. The three-row configuration supports significant I/O density within a constrained footprint. The right-angle design facilitates cable routing perpendicular to the board plane. Gold plating ensures reliable signal transmission over extended service life. Verify thermal endurance requirements against the 125 C maximum operating limit.

Part Context

This part belongs to the AirBorn W Series, a line of rectangular connectors known for meeting stringent military standards. The series offers various configurations to support diverse aerospace and defense applications. As a Molex product, it inherits established quality controls and material specifications. The WG104 variant specifically addresses high-pin-count requirements in compact form factors.

Replacement Considerations

Compatible substitutes include other MIL-DTL-55302 compliant connectors with matching 104-position, 3-row, right-angle specifications. Cross-reference pin assignments and housing dimensions to ensure mechanical interchangeability. Verify electrical ratings match or exceed the original requirements. Consult Molex technical resources for approved alternative part numbers within the W Series.
