306-020-521-102

Overview

The EDAC Inc. model 306-020-521-102 is a standard card edge connector designed for panel mount applications. It features a dual female configuration with 40 positions arranged in two rows, providing a total of 80 contact points. The connector utilizes a 3.96 mm (0.156 inch) pitch spacing between contacts. It is engineered to accept printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). The housing is constructed from green thermoplastic polyester, and the contacts are made of copper alloy with a tin plating finish.

Feature Summary

• Dual female contact configuration for secure board insertion
• Vertical panel mount installation style with flanged design
• Compatible with non-specified double-sided card edge PCBs
• Tin-plated copper alloy contacts for reliable conductivity

Applications

• Industrial control systems requiring robust interconnects
• Medical equipment needing reliable signal transmission
• Aerospace and defense electronic assemblies
• Computing and storage hardware backplanes

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current catalog to ensure compatibility with required board thickness and contact plating options. Confirm that the dual-row configuration matches the target PCB footprint. Check RoHS compliance status if environmental regulations apply to the end product. Ensure the vertical panel mount style aligns with the mechanical enclosure design constraints before finalizing procurement orders.

Selection Notes

Select this component when a dual-row connection is necessary for high-density signal routing on standard thickness PCBs. The 3.96 mm pitch offers a balance between pin count and spacing reliability. Consider the tin plating for general-purpose applications where gold plating is not strictly required for corrosion resistance or low contact resistance. Verify that the panel mount flange dimensions fit within the available chassis space.

Part Context

This part belongs to the EDAC 306 series, which specializes in standard card edge connectors for various industries. The series is known for providing versatile interconnect solutions for computing, medical, and industrial sectors. EDAC has established itself as a leader in rack and panel applications since 1966, offering a wide range of interconnect products designed for durability and performance in demanding environments.

Replacement Considerations

Direct substitutes may include other EDAC 306 series variants with different position counts or plating options. Cross-brand replacements require matching the 3.96 mm pitch, dual-row layout, and 1.57 mm board thickness tolerance. Verify that alternative parts support the same vertical panel mount style and flange specifications to ensure mechanical compatibility.
