305-044-555-504

Edgeboard Connectors Overview

The EDAC Inc. 305-044-555-504 is a standard card edge connector from the 305 series, designed for dual-edge female connections with 44 positions. It features a 0.156-inch (3.96 mm) contact pitch and accepts non-specified dual-edge cards. The connector utilizes gold-plated copper alloy contacts with a 10.0 µin thickness and offers a 5 A current rating. It supports panel mounting in a vertical orientation with solder lug termination. The housing is green thermoplastic polyester, rated for operation between -40°C and +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact pin count and plating specifications. Ensure compatibility with the target PCB stack-up and mating card thickness range of 0.054 to 0.070 inches. Confirm RoHS compliance status through the manufacturer's latest environmental declarations before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a high-density 44-position interface is required for dual-edge applications. The 3.96 mm pitch accommodates standard board widths while maintaining robust mechanical stability. Consider the vertical panel mount style for chassis-based architectures where space efficiency and direct board access are prioritized over surface-mounted alternatives.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, a line of standard card edge connectors known for durability in harsh environments. The series supports various position counts and mounting styles, providing modular solutions for electronic systems requiring frequent board changes or high-reliability connections in industrial and commercial sectors.

Edgeboard Connectors Replacement Considerations

Cross-reference with EDAC 305-044-521-202 for similar form factors. Verify that alternative parts match the 0.156 inch pitch and 44-position requirement. Ensure mechanical dimensions and termination types are identical to maintain assembly integrity without redesigning the host panel.
