Overview
The EDAC Inc. 306-022-421-108 is a standard card edge connector receptacle designed for panel mount applications. It features a dual female configuration with 44 positions arranged in two rows. The connector utilizes a 0.156-inch (3.96 mm) pitch and supports a board thickness of 1.57 mm. Electrical specifications include a current rating of 5 A per contact. The contacts are gold-plated copper alloy, terminated via solder pins. The housing is constructed from thermoplastic polyester.
Feature Summary
- Dual female contact configuration for secure card edge insertion
- Gold-plated copper alloy contacts for reliable conductivity
- Thermoplastic polyester housing for structural integrity
- Solder pin termination for robust PCB attachment
Applications
- Industrial control panel interconnections
- High-density signal routing in electronic assemblies
- Panel-mounted modular system integration
Procurement Notes
Verify the specific ordering suffix to confirm the exact contact length, plating thickness, and mounting hardware configuration required for your application. Ensure compatibility with the target PCB edge card dimensions, specifically the 1.57 mm thickness constraint. Confirm that the 5 A current rating aligns with the electrical load requirements of the circuit design before finalizing procurement.
Selection Notes
Select this component when a high-position-count, dual-row card edge interface is required for panel mounting. The 0.156-inch pitch offers a balance between density and spacing. Consider the gold plating for corrosion resistance in demanding environments. Verify that the solder pin termination method matches the assembly process capabilities of the manufacturing facility.
Part Context
This part belongs to the EDAC 306 series, which focuses on standard card edge connectors. The series provides various position counts and pitch options to accommodate different board sizes. The 306 series is characterized by its use of thermoplastic polyester housings and standardized solder pin terminations, ensuring consistent mechanical performance across the product line.
Replacement Considerations
Direct substitutes within the same series include parts with identical pitch and position counts but different suffixes indicating variations in contact length or plating. Cross-series replacements require matching the 0.156-inch pitch and 44-position dual-row layout. Verify mechanical fit and electrical ratings before substituting.
