306-021-500-112

Overview

The EDAC Inc. 306-021-500-112 is a dual female card edge connector featuring 42 positions with a 0.156-inch (3.96mm) contact spacing. It utilizes gold-plated copper alloy contacts and accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). The component employs a low-profile insulator body and supports through-hole mounting via solder termination. Designed for non-specified dual-edge cards, it operates within a temperature range of -40°C to 105°C.

Feature Summary

• Dual female configuration with single centerline row architecture
• Gold-plated copper alloy contacts for reliable signal transmission
• Low-profile insulator body design for space-constrained applications
• Through-hole solder termination for secure PCB attachment

Applications

• Computing and storage systems interconnects
• Industrial control board connections
• Communications network equipment interfaces

Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm plating thickness and flange characteristics. Ensure compatibility with target PCB thickness specifications before procurement. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Cross-reference the manufacturer part number with distributor catalogs to avoid variant mismatches.

Selection Notes

Select this connector when a dual-edge card interface with 0.156-inch pitch is required. Evaluate the low-profile body height against available vertical clearance in the enclosure. Consider the gold plating for corrosion resistance in demanding environments. Verify that the 42-position count aligns with the signal routing requirements of the target application board.

Part Context

This component belongs to the EDAC 306 series of standard card edge connectors. The series offers various position counts and termination styles. The 306-021-500-112 specifically addresses needs for dual-edge connectivity with high-density pin arrangements. It represents a solution for robust mechanical and electrical connections in modular electronic assemblies.

Replacement Considerations

Consult the official EDAC 306 Series Ordering Guide for direct substitutes. Verify that alternative parts maintain the same 0.156-inch pitch and 42-position count. Ensure mechanical footprint compatibility with existing PCB layouts. Check if modified flange features or termination types are acceptable for the specific installation.
