305-076-521-503

Edgeboard Connectors Overview

The EDAC Inc. 305-076-521-503 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 76 positions arranged in a dual-edge configuration, utilizing 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. Constructed with copper alloy contacts that are gold-plated, it ensures reliable electrical performance. The unit employs a solder pin termination method and utilizes a green thermoplastic polyester insulator body.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact mechanical dimensions and plating specifications. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Confirm RoHS compliance status through the latest product documentation provided by EDAC Inc. to meet regulatory requirements for your specific application environment.

Edgeboard Connectors Selection Notes

Select this component when a high-density connection with 76 positions is required for vertical panel mounting. The 3.96 mm pitch suits applications needing wider spacing compared to standard 2.54 mm connectors. Verify that the dual-edge configuration aligns with the signal routing strategy of the host PCB. Consider the thermal operating range of -40°C to 105°C for environmental suitability.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of edgeboard connectors, which are engineered for durability in demanding environments. The series offers various position counts and configurations to support diverse industrial and commercial electronic designs. EDAC specializes in interconnect solutions for medical, agricultural, and general industrial sectors, emphasizing reliability and precise mechanical fit.

Edgeboard Connectors Replacement Considerations

Cross-reference the 305-076-521-503 with other EDAC 305 series variants having identical 76-position dual-edge specifications. Verify that substitute parts maintain the same 3.96 mm pitch and 1.57 mm board thickness acceptance. Ensure mechanical mounting dimensions and terminal type match exactly to avoid PCB redesign.
