306-025-420-168

Overview

The EDAC Inc. model 306-025-420-168 is a standard dual-edge card edge connector designed for vertical panel mounting applications. This component features a single centerline row with 50 positions and a contact spacing of 0.156 inches (3.96 mm). It utilizes female contacts with a tin plating finish to ensure reliable signal transmission. The insulator body is constructed from green thermoplastic material, providing structural integrity and electrical insulation. The connector is engineered to accept printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm), ensuring secure mechanical engagement.

Feature Summary

• Dual-edge female contact configuration for non-specified board types
• Low-profile insulator body design for space-constrained installations
• Vertical panel mount orientation for stable PCB integration

Applications

• Industrial control system interface modules
• Telecommunications equipment backplanes
• Computer peripheral expansion slots

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm contact plating and color specifications. Ensure the selected variant matches the required board thickness tolerance of 0.062 inches. Confirm availability status through authorized distributors as supply chain conditions may vary. Cross-reference the part number with official EDAC documentation to validate pin count and spacing parameters before procurement.

Selection Notes

Select this connector when a low-profile, dual-edge solution is required for 50-position interfaces. The 3.96 mm pitch accommodates standard board layouts while maintaining robust mechanical retention. Consider the tin-plated contacts for cost-effective applications where high corrosion resistance is not critical. Verify that the panel mounting style aligns with the chassis design requirements for the target assembly.

Part Context

This component belongs to the EDAC 306 series of standard card edge connectors. The series is characterized by its versatility in handling various board thicknesses and its suitability for general-purpose interconnect applications. The 306 series provides a balance of electrical performance and mechanical durability for industrial and commercial electronic systems requiring reliable signal routing.

Replacement Considerations

Direct substitutes include EDAC part numbers within the same 306 series family that share identical pin counts, pitch, and mounting styles. Verify compatibility with existing tooling and board footprints when considering alternative variants from the same manufacturer.
