306-036-420-178

Overview

The EDAC Inc. 306-036-420-178 is a standard card edge connector receptacle designed for through-hole mounting. It features a dual female configuration with 72 positions arranged in two rows, providing a total contact count of 72. The connector utilizes a .156 inch (3.96 mm) contact spacing and is engineered to accept printed circuit boards with a nominal thickness of .062 inch (1.57 mm). The insulator body is constructed from thermoplastic polyester, offering low-profile characteristics suitable for space-constrained applications.

Feature Summary

• Dual female contact configuration provides 72 positions for robust signal and power distribution across double-sided card edges.
• Low-profile insulator body design minimizes vertical height requirements while maintaining structural integrity for board insertion.
• Through-hole termination style ensures secure mechanical attachment to the target PCB with solder joint reliability.

Applications

• Industrial control systems requiring reliable double-sided card edge interfaces
• Telecommunications equipment utilizing modular board architectures
• Test and measurement instrumentation with standardized connector footprints

Procurement Notes

Verify that the target application requires a dual-row receptacle rather than a single-row variant. Confirm the PCB thickness matches the .062 inch specification to ensure proper retention force. Check for RoHS compliance requirements if operating in regulated environments. Ensure the mounting orientation aligns with the straight installation style specified for this part number.

Selection Notes

Select this component when a high-density connection interface is required for double-sided cards. The 72-position capacity supports complex signal routing compared to lower-count alternatives. Consider the .156 inch pitch as a standard industry spacing for compatibility with existing board designs. Evaluate the through-hole mounting requirement against surface-mount options if space or assembly methods differ.

Part Context

This part belongs to the EDAC 306 series of standard card edge connectors. The series is characterized by its use of thermoplastic polyester insulators and copper alloy contacts with gold plating. The 306 series offers various position counts and row configurations to accommodate different board sizes and connectivity needs within industrial and commercial electronics.

Replacement Considerations

Direct substitutes must match the 72-position dual-row format and .156 inch pitch. Verify that any replacement maintains the same .062 inch board thickness tolerance and through-hole termination style. Cross-reference with other EDAC 306 series variants to ensure identical mechanical dimensions and electrical ratings before substitution.
