387-025-559-158

Edgeboard Connectors Overview

The EDAC Inc. 387-025-559-158 is a single-row card edge connector featuring 25 female positions with a 0.156-inch (3.96mm) spacing. Designed for through-hole mounting, it utilizes wire wrap termination and cantilever contacts made of copper alloy with 10.0µin gold plating. The housing is black thermoplastic polyester, supporting board thicknesses from 0.054 to 0.070 inches. It operates within a temperature range of -40°C to 105°C and includes flange features for flush mounting with top openings and 4-40 threaded inserts.

Edgeboard Connectors Feature Summary

• Cantilever contact design ensures reliable mating with specified card edge thicknesses
• Wire wrap termination provides secure electrical connection without soldering
• Gold-plated copper alloy contacts offer corrosion resistance and low contact impedance
• Thermoplastic polyester insulation supports high-temperature industrial environments

Edgeboard Connectors Applications

• Industrial control system backplanes
• Embedded computing module interconnects
• Test and measurement equipment signal routing
• Telecommunications hardware expansion slots

Edgeboard Connectors Procurement Notes

Verify the complete part number including suffix codes to ensure correct termination style and flange configuration. Confirm RoHS compliance status matches project requirements. Check datasheet for specific board thickness tolerances to guarantee mechanical fit. Validate supplier authenticity through authorized distribution channels only.

Edgeboard Connectors Selection Notes

Choose this component when wire wrap termination is preferred over soldering for serviceability. Select based on required pin count and 0.156-inch pitch compatibility. Ensure enclosure design accommodates the specified flange mounting holes. Consider thermal operating limits for harsh environment deployments.

Edgeboard Connectors Part Context

Part of the EDAC 387 series standard card edge connectors. This series offers various position counts and termination options. The 387-025 variant specifically addresses applications requiring 25 connections in a single row format with robust mechanical retention capabilities.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 387-series parts for different pin counts or termination types. Verify mechanical dimensions against existing PCB layouts before substitution. Ensure equivalent electrical ratings and material specifications are maintained.
