345-142-523-878

Edgeboard Connectors Overview

The EDAC Inc. 345-142-523-878 is a dual-edge female card edge connector with 142 positions arranged in two rows of 71 contacts each. It features a 0.100-inch (2.54mm) pitch and utilizes gold-plated cantilever spring contacts for reliable signal transmission. Designed for through-hole mounting, the unit includes flanges with top-mounted openings to secure the assembly. The connector supports printed circuit boards with thicknesses ranging from 0.054 inches to 0.070 inches. Constructed with thermoplastic polyester insulation, it operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and flange specifications. Ensure compatibility with target PCB thickness limits before integration. Confirm RoHS compliance status via current manufacturer datasheets. Cross-reference ordering numbers with authorized distributors to avoid counterfeit components. Validate mechanical dimensions against enclosure constraints during the design phase.

Edgeboard Connectors Selection Notes

Select this component when a high-density dual-row interface is required for standard thickness cards. The 0.100-inch pitch accommodates common trace spacing rules. Evaluate the need for flanged mounting versus free-hanging configurations based on structural requirements. Consider the operating temperature range if the environment exceeds standard commercial limits. Ensure the cantilever contact style matches the mating card insertion force expectations.

Edgeboard Connectors Part Context

This part belongs to the EDAC 345 series of standard card edge connectors. The series offers various position counts and mounting options for diverse electronic applications. Components in this family share consistent pitch dimensions and contact material standards. The 345 series is widely recognized for its reliability in harsh environments. This specific model represents a mid-range position count option within the dual-edge product line.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 142-position count, dual-edge female configuration, and 0.100-inch pitch. Verify that alternative parts support the same PCB thickness range of 0.054 to 0.070 inches. Ensure compatible flange mounting styles if panel installation is required. Check for equivalent gold plating specifications to maintain signal integrity. Consult EDAC official cross-reference lists for validated replacement part numbers.
