342-049-559-101

Edgeboard Connectors Overview

The EDAC Inc. model 342-049-559-101 is a standard card edge connector socket designed for through-hole mounting. It features a single-sided configuration with 49 positions and a 2.54 mm (0.100 inch) pitch. The connector supports PCB thicknesses of 1.57 mm and utilizes gold-plated copper alloy contacts to ensure reliable electrical performance. Rated for 3 A current, it employs a thermoplastic polyester housing and wire wrap termination style. This component is part of the EDAC 342 series, offering vertical orientation for secure board-to-board interconnection.

Edgeboard Connectors Procurement Notes

Verify the specific datasheet version for the 342-049-559-101 to confirm RoHS compliance status and any recent product change notifications. Ensure that the receiving facility has the appropriate wire wrap tools compatible with the specified termination style. Cross-reference the 49-position count against the target PCB footprint to guarantee mechanical alignment before placing orders.

Edgeboard Connectors Selection Notes

Select this component when a single-row, 49-position interface is required with a standard 2.54 mm pitch. The wire wrap termination is suitable for applications where high vibration resistance is needed without soldering. Consider the 1.57 mm PCB thickness constraint and verify that the mating card edge meets the dimensional tolerances defined in the official EDAC documentation for the 342 series.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 342 series, which specializes in standard card edge sockets. The series offers various position counts and termination options to accommodate diverse electronic assembly needs. The 342-049-559-101 specifically addresses the need for a mid-range density connection with robust mechanical retention and reliable signal transmission capabilities in compact form factors.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the EDAC family include the 392-049-559-101, which shares similar electrical characteristics but may differ in housing color or specific material certifications. Verify pinout compatibility and mechanical dimensions before swapping. No cross-manufacturer replacements are confirmed in public data.
