Overview
The EDAC Inc. 306-025-420-112 is a standard card edge connector from the 306 series, designed for panel mount vertical installation. It features 50 positions in a dual female configuration with a 0.156-inch (3.96mm) pitch. The contacts are tin-plated copper alloy, rated for 5A current. The housing is green thermoplastic, supporting board thicknesses of 0.051 to 0.071 inches. Operating temperatures range from -40°C to +105°C.
Feature Summary
- Dual-edge female contact design for secure board insertion
- Vertical panel mount orientation for structural stability
- Tin-plated copper alloy contacts for reliable conductivity
- Thermoplastic housing provides electrical insulation and durability
Applications
- Industrial control system interconnects
- Telecommunications equipment backplanes
- Test and measurement instrument modules
- Computing hardware peripheral interfaces
Procurement Notes
Verify the specific ordering suffix against the manufacturer datasheet to confirm contact plating and housing color variations. Ensure the target PCB thickness falls within the specified 0.051 to 0.071 inch range for proper mechanical retention. Confirm that the vertical panel mount style aligns with the enclosure design requirements before finalizing procurement.
Selection Notes
Select this component when a dual-edge connection is required for thicker circuit boards compared to single-row standards. The 3.96mm pitch accommodates higher pin counts within limited widths. Verify that the tin plating meets environmental corrosion resistance needs, as gold options exist in the same series for different performance profiles.
Part Context
This part belongs to the EDAC 306 series of standard card edge connectors. The series offers various position counts and mounting styles. The 306-025-420-112 specifically addresses applications needing robust dual-edge connectivity with a 50-position capacity, distinguishing it from single-row or smaller pitch variants in the broader product line.
Replacement Considerations
Cross-reference with EDAC 306-025-520-107 if gold plating is preferred over tin. Verify compatibility with EDAC 302 series components only if pitch reduction to 1.27mm is acceptable. No direct substitutes from other manufacturers are confirmed without custom engineering.
