305-086-521-508

Edgeboard Connectors Overview

The EDAC Inc. 305-086-521-508 is a standard card edge connector receptacle featuring 86 positions in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing with a 3.56 mm row spacing, designed for 1.57 mm nominal thickness printed circuit boards. The component employs gold-plated copper alloy contacts and solder pin termination for secure PCB mounting. Rated for 5 A current at operating temperatures ranging from -40°C to +105°C, it offers reliable electrical performance.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm exact mechanical dimensions and plating specifications. Ensure compatibility with target PCB stack-up and mating card edge profiles before procurement. Cross-reference manufacturer datasheets for updated environmental compliance status and lead time variations.

Edgeboard Connectors Selection Notes

Select this model when high-density interconnection is required with robust mechanical stability. The 3.96 mm pitch suits applications needing fewer rows than finer pitches while maintaining substantial contact count. Verify thermal management requirements against the 105°C maximum rating and ensure housing material compatibility with assembly processes.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its specific 3.96 mm spacing and thermoplastic housing construction. It serves as a critical interface solution within broader EDAC interconnect portfolios for industrial and commercial electronic assemblies.

Edgeboard Connectors Replacement Considerations

Direct substitutes include EDAC part numbers sharing the same 305 series designation, 86 position count, and 3.96 mm pitch. Verify mechanical footprint and terminal type equivalence before substitution.
