306-025-421-104

Overview

The EDAC Inc. 306-025-421-104 is a dual-edge female card edge connector designed for panel and through-hole mounting. It features 50 positions with a 0.156-inch (3.96mm) contact spacing arranged in a single centerline row. The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). Contact surfaces are tin-plated copper alloy, housed in a green thermoplastic polyester insulator. Operating temperatures range from -40°C to +105°C.

Feature Summary

• Dual-edge receptacle configuration with 50 female contacts
• Accepts standard 0.062 inch nominal thickness PCBs
• Tin-plated copper alloy contacts for reliable connection
• Green thermoplastic polyester insulator body

Applications

• Panel-mounted electronic assemblies requiring vertical interconnect
• Industrial control systems utilizing standard card edge modules
• Test and measurement equipment interfaces
• General-purpose backplane or daughterboard connections

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current catalog to ensure compatibility with required plating and insulation materials. Confirm that the target application utilizes PCBs within the specified thickness tolerance. Check for RoHS compliance status updates prior to final procurement authorization.

Selection Notes

Select this component when a low-profile, dual-edge female connector is required for 0.062 inch thick boards. The 0.156 inch pitch suits applications where higher density is not critical but robust mechanical retention via panel mounting is necessary. Ensure the tin finish meets the environmental requirements of the deployment zone.

Part Context

This part belongs to the EDAC 306 Series, which specializes in standard card edge connectors. The series offers various position counts and mounting styles, providing a modular solution for industrial interconnect needs. The 306 series is characterized by its durable construction and standardized dimensions compatible with common industry board profiles.

Replacement Considerations

Cross-reference with other EDAC 306 series variants such as 306-025-421-102 for gold-plated alternatives. Verify mechanical footprint compatibility before substituting with non-OEM equivalents. Ensure replacement parts maintain the same 0.156 inch pitch and 0.062 inch board thickness acceptance.
