306-027-521-101

Overview

The EDAC Inc. 306-027-521-101 is a dual-edge female card edge connector designed for high-reliability applications. It features 54 positions with a contact spacing of 0.156 inches (3.96 mm). The connector utilizes gold-plated contacts and a green insulator body made from thermoplastic material. It supports printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). The component operates within a temperature range of -40°C to +105°C and employs through-hole termination for secure PCB mounting.

Feature Summary

• Dual-edge female configuration accepting standard double-sided PCBs
• Gold-plated contacts ensure reliable signal transmission
• Low-profile insulator body design for space-constrained assemblies
• Through-hole termination provides robust mechanical stability

Applications

• Industrial control systems requiring durable interconnects
• Telecommunications equipment board-to-board connections
• Test and measurement instrumentation interfaces
• Automotive electronics modules

Procurement Notes

Verify the specific part number against official EDAC documentation to confirm pin count, spacing, and termination style. Ensure compatibility with target PCB thickness specifications before procurement. Cross-reference manufacturer datasheets for updated environmental ratings and RoHS compliance status to meet project requirements.

Selection Notes

Select this connector when a dual-edge interface with 0.156-inch pitch is required. Consider the operating temperature range and low-profile form factor for integration into compact enclosures. Validate that the through-hole mounting method aligns with the assembly process and mechanical stress requirements of the final application.

Part Context

This component belongs to the EDAC 306 series of card edge connectors. The series offers various row counts and termination options tailored for different board densities. The 306 series is characterized by its standardized dimensions and reliable performance in demanding electronic environments.

Replacement Considerations

Direct substitutes must match the 54-position count, 0.156-inch pitch, and dual-edge female configuration. Verify identical mounting style and electrical ratings before substitution.
