387-044-559-212

Edgeboard Connectors Overview

The EDAC Inc. 387-044-559-212 is a dual-edge female card edge connector from the 387 series, designed for through-hole mounting. It features 44 positions with a 0.156-inch (3.96 mm) pitch and a 0.200-inch (5.08 mm) row spacing. The contacts are made of copper alloy with gold plating, ensuring reliable signal transmission. The housing is constructed from black thermoplastic polyester, rated for operation between -40°C and +105°C. This component supports standard PCB thicknesses and provides secure mechanical retention for dual-sided edge cards.

Edgeboard Connectors Procurement Notes

Verify the specific flange configuration and termination style against the official datasheet before ordering, as the 387 series offers various mounting options. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region. Ensure the selected variant matches the required PCB thickness and panel guide rail specifications for proper mechanical fit.

Edgeboard Connectors Selection Notes

Select this connector when a dual-edge interface with 44 positions is required. The 0.156-inch pitch accommodates standard card edge designs. Consider the operating temperature range and current rating requirements to ensure compatibility with the application environment. Verify that the through-hole mounting style aligns with the manufacturing process and PCB design constraints.

Edgeboard Connectors Part Context

This component belongs to the EDAC 387 series, which specializes in card edge connectors with a 0.156-inch pitch. The series includes single and dual-edge variants with various pin counts and mounting styles. The 387 series is widely used in applications requiring reliable high-density interconnections, offering a balance of performance and mechanical stability for industrial and commercial electronic systems.

Edgeboard Connectors Replacement Considerations

Check for direct substitutes within the EDAC 387 series or compatible families such as the 357 series if pitch differences are acceptable. Verify that any replacement part maintains the same 44-position count, dual-edge configuration, and 0.156-inch pitch to ensure mechanical and electrical compatibility without redesigning the PCB footprint.
