305-076-555-507

Edgeboard Connectors Overview

The EDAC Inc. 305-076-555-507 is a standard card edge connector from the 305 series, designed for dual-row applications with a 76-position configuration. It features a 3.96 mm (0.156 inch) contact spacing and a 3.56 mm row spacing. The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Constructed with copper alloy contacts, it offers gold plating on the mating area and tin plating with nickel underplating on the tails. The unit provides a current rating of 5 amps and utilizes a solder termination type for secure board attachment.

Edgeboard Connectors Procurement Notes

Verify the specific termination style and mounting orientation against project requirements before procurement. Confirm that the 76-position count aligns with the target PCB design. Ensure compatibility with the specified 1.57mm board thickness to guarantee proper mechanical fit. Cross-reference the manufacturer's latest documentation for any updates to the physical dimensions or material specifications.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge solution with 3.96mm pitch is required. The 76-position count suits high-density interconnect needs. Verify that the straddle mount style fits the enclosure constraints. Ensure the 5A current rating meets the electrical load requirements of the application circuitry.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting options while maintaining consistent 3.96mm pitch characteristics. The 305-076-555-507 specifically addresses the need for a 76-position dual-row interface in panel-mounted configurations.

Edgeboard Connectors Replacement Considerations

Compatible substitutes within the 305 series include parts with identical 3.96mm pitch and dual-row layouts, such as the 305-048-555-507 or 305-054-555-507, provided the position count difference is acceptable for the design.
