Overview
The EDAC Inc. model 306-027-421-107 is a standard card edge connector designed for dual-edge female applications. It features 54 positions with a pitch of 0.156 inches (3.96 mm). The connector supports a PCB thickness of 1.57 mm and utilizes tin-plated contacts made from copper alloy. Rated for 5 A current, it employs thermoplastic polyester housing and offers an insulation resistance of 5 GOhms.
Feature Summary
- Dual-edge female configuration for secure board insertion
- Tin-plated copper alloy contacts for reliable conductivity
- Thermoplastic polyester housing for structural integrity
Applications
- Industrial control systems requiring high-density connections
- Telecommunications equipment interface modules
- Consumer electronics assembly with dual-edge card requirements
Procurement Notes
Verify the specific ordering suffix to confirm contact plating and housing color specifications. Ensure compatibility with the target PCB thickness of 1.57 mm during integration planning. Confirm that the 54-position layout aligns with the mechanical constraints of the receiving enclosure. Cross-reference the manufacturer datasheet for precise mating force requirements before finalizing the design.
Selection Notes
Select this component when a dual-edge female connector is required for 54-position interfaces. The 3.96 mm pitch accommodates standard board widths while maintaining signal integrity at 5 A ratings. Consider the tin plating option if cost efficiency is prioritized over extended corrosion resistance compared to gold variants. Verify panel mount or vertical orientation needs against the system architecture.
Part Context
This part belongs to the EDAC 306 series of standard card edge connectors. The series provides various position counts and mounting styles for diverse electronic interconnect needs. The 306-027 variant specifically addresses dual-edge applications, distinguishing it from single-edge counterparts within the same product family line.
Replacement Considerations
Direct substitutes include EDAC models 306-027-421-168, which shares the 54-position dual-edge female specification. Verify pin count and pitch compatibility before substitution. Ensure housing material and current rating meet or exceed original design requirements.
