306-027-521-102

Overview

The EDAC Inc. model 306-027-521-102 is a dual female card edge connector designed for vertical PCB mounting. It features 54 positions with a contact spacing of 0.156 inches (3.96 mm). The component accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). The housing utilizes a low-profile thermoplastic polyester insulator body, ensuring compact integration within electronic assemblies while maintaining reliable signal transmission through gold-plated contacts.

Feature Summary

• Dual female contact configuration for secure board insertion
• Low-profile insulator body design for space-constrained applications
• Vertical mounting orientation for standard PCB assembly

Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing modular board architectures
• Computing hardware employing expansion or daughter card configurations

Procurement Notes

Verify the specific ordering suffix to confirm contact plating, housing material, and mounting style variations. Ensure compatibility with target PCB thickness specifications before procurement. Confirm that the selected variant meets all required environmental ratings and current carrying capacity standards for the intended operational environment.

Selection Notes

Select this connector when a dual-sided female interface is required for 54-position signal routing. The 0.156-inch pitch accommodates standard trace widths for general-purpose digital signals. Consider the vertical form factor for direct board-to-board or backplane connections where space efficiency is prioritized over angled access.

Part Context

This component belongs to the EDAC 306 series of standard card edge connectors. The series offers various position counts and termination styles to support diverse electronic packaging needs. The 306 series is engineered for high reliability in demanding environments, providing consistent electrical performance across a wide range of industrial and commercial applications.

Replacement Considerations

Cross-reference with EDAC part numbers sharing the same 54-position count and 0.156-inch pitch. Verify mechanical dimensions and contact configuration compatibility before substitution. Ensure alternative components meet identical thermal and electrical performance criteria.
