305-072-521-512

Edgeboard Connectors Overview

The EDAC Inc. 305-072-521-512 is a standard card edge connector receptacle featuring 72 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) pitch and is designed for PCB mount installation with a straight orientation. The contacts are made of copper alloy with gold plating, supporting a current rating of 5 A. The housing is constructed from green thermoplastic polyester, accommodating board thicknesses of 1.57 mm. It operates within a temperature range of -40°C to +105°C and offers an insulation resistance of 5 GOhms.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact pin count, row configuration, and termination style. Ensure compatibility with target PCB thickness and mating card dimensions before procurement. Confirm RoHS compliance status if required by project specifications.

Edgeboard Connectors Selection Notes

Select this component when a high-density 72-position interface is required for double-sided edge cards. The 3.96 mm pitch suits applications needing robust mechanical retention. Verify that the 5 A current rating meets the electrical load requirements of the connected circuitry.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its use of thermoplastic polyester housings and gold-plated contacts. It is designed for through-hole soldering onto printed circuit boards, providing a stable connection for modular electronic systems.

Edgeboard Connectors Replacement Considerations

Cross-reference with EDAC part numbers sharing the same 72-position, dual-row, 3.96 mm pitch specification. Verify identical mounting style and contact plating to ensure functional interchangeability without redesigning the PCB footprint.
