345-040-500-878

Edgeboard Connectors Overview

The EDAC Inc. 345-040-500-878 is a standard card edge connector featuring 40 positions with a 2.54 mm (0.100 inch) pitch. Designed for dual-edge board insertion, it utilizes female contacts plated with gold over a copper alloy substrate. The housing is constructed from green thermoplastic polyester, supporting a maximum current rating of 3 A and an insulation resistance of 5 GOhms. It accommodates PCB thicknesses between 1.37 mm and 1.78 mm. Installation is achieved via through-hole termination with wire wrap end connections. The component operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to confirm exact physical dimensions and plating specifications. Ensure compatibility with target PCB stack-up regarding hole size and pad layout. Confirm RoHS compliance status if required by project regulations. Cross-reference the manufacturer part number with distributor catalogs to validate current availability and lead times before finalizing procurement plans.

Edgeboard Connectors Selection Notes

Select this connector when a vertical, dual-edge interface is required for boards up to 1.78 mm thick. The 40-position count suits moderate-density applications. Verify that the wire wrap termination method aligns with the assembly process capabilities. Ensure the operating environment remains within the specified -40°C to +105°C range. Consider the flange design for panel mounting stability if mechanical fixation is necessary.

Edgeboard Connectors Part Context

This component belongs to the EDAC 345 series of standard card edge connectors. The series offers various position counts and termination styles. The 345-040-500-878 specifically denotes a 40-position dual-edge variant. It is designed for robust industrial and commercial applications requiring reliable electrical connectivity between rigid PCBs and backplanes or chassis-mounted sockets.

Edgeboard Connectors Replacement Considerations

Direct substitutes may include other EDAC 345 series parts with identical 40-position dual-edge configurations. Verify pinout compatibility and mechanical footprint before substitution. Alternative manufacturers offering 2.54 mm pitch dual-edge connectors must match the current rating and insulation resistance specifications.
