895-142-556-504

Edgeboard Connectors Overview

The EDAC Inc. 895-142-556-504 is a standard card edge connector receptacle featuring 142 positions arranged in a dual-row configuration. It utilizes a 0.100-inch (2.54mm) pitch and is designed for non-specified dual-edge cards with a thickness range of 1.57mm. The connector employs gold-plated copper alloy contacts with a solder pin termination method. Constructed with a black polyphenylene sulfide (PPS) housing, it supports panel mount installation at a vertical orientation. The component operates within a temperature range of -40°C to +125°C and carries an insulation resistance of 5 GOhms.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 895 Series Ordering Guide to ensure exact mechanical and electrical alignment. Confirm that the target application requires a dual-edge card interface compatible with the specified 0.100-inch pitch. Check RoHS3 compliance status if environmental regulations apply to the final assembly. Ensure panel mounting provisions match the vertical orientation specifications provided in the datasheet.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count dual-row connection is required for vertical panel mounting applications. The 142-position count suits complex signal routing needs in industrial or communication sectors. Verify that the PCB card thickness falls within the supported range for proper contact engagement. Consider the PPS material properties for environments demanding high thermal resistance and stable insulation performance.

Edgeboard Connectors Part Context

This part belongs to the EDAC 895 series of standard card edge connectors, which are widely used in various electronic assemblies. The series offers multiple position counts and mounting styles to accommodate diverse design requirements. As a receptacle type, it interfaces directly with corresponding card edge plugs, forming a robust connection system for board-to-board or backplane applications.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 895 Series Ordering Guide for direct substitutes with differing position counts or mounting variations. Cross-reference with other EDAC series such as the 845 or 395 only if mechanical dimensions and electrical ratings are fully compatible. No generic industry equivalents should be assumed without verifying pin pitch, contact plating, and housing material specifications.
