337-040-542-208

Edgeboard Connectors Overview

The EDAC Inc. 337-040-542-208 is a standard card edge connector from the 337 series, designed for through-hole vertical mounting. It features 40 positions arranged in a dual-row configuration with a 3.96 mm (0.156 inch) pitch. The connector accepts non-specified dual-edge cards with thicknesses ranging from 1.37 mm to 1.78 mm. Contacts are made of copper alloy with gold plating and utilize a cantilever spring contact type. The housing is constructed from green thermoplastic polyester, providing an insulation resistance of 5 GOhms. Rated for 3 A current, it operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify RoHS compliance status and REACH registration details prior to procurement, as environmental declarations may vary by production batch. Confirm that the specific ordering suffix matches the required flange configuration and contact plating specifications. Ensure compatibility with the target PCB layout regarding hole spacing and component clearance. Check current supply chain availability as distribution status can change without notice.

Edgeboard Connectors Selection Notes

Select this model when a dual-row, 40-position connection is required for boards up to 1.78 mm thick. The 3.96 mm pitch suits applications needing higher pin density than 5.08 mm options. Verify that the vertical orientation and through-hole termination align with the mechanical assembly constraints. Consider the operating temperature range if the environment exceeds standard commercial limits.

Edgeboard Connectors Part Context

This component belongs to the EDAC 337 series of standard card edge connectors. The series offers various position counts and row configurations to support diverse interface requirements. EDAC designs these connectors for durability in industrial and medical environments, emphasizing robust mechanical retention and electrical stability across the specified temperature spectrum.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include part numbers such as 337-040-540-804 or 337-040-541-107, depending on whether single or dual edge contact styles are needed. Verify that any replacement maintains the 3.96 mm pitch and 40-position count to ensure mechanical fit.
