306-021-521-102

Overview

The EDAC Inc. 306-021-521-102 is a standard card edge connector featuring 21 contacts arranged in a single row of female terminals. It utilizes a 0.156-inch pitch and accepts printed circuit boards with a nominal thickness of 0.062 inches. The component employs a solder terminal interface for secure attachment and incorporates a green insulator body. Designed for straight, low-profile installation, it provides reliable electrical interconnection for edgeboard applications requiring specific board thickness compatibility.

Feature Summary

• Single centerline row configuration for compact layout integration
• Low profile insulator body design to minimize vertical space requirements
• Accepts nominal 0.062 inch thickness printed circuit boards
• Female contact type ensures secure mating with card edge fingers

Applications

• Standard card edge interconnect systems
• Edgeboard connectors for industrial electronics
• Straight mount PCB assembly applications
• Low profile electronic module connections

Procurement Notes

Verify the exact part number suffix against official EDAC documentation to confirm terminal style, plating specifications, and mounting orientation. Ensure the target application supports the specified 0.156-inch pitch and 0.062-inch board thickness constraints. Cross-reference manufacturer datasheets for environmental ratings and mechanical durability metrics before finalizing procurement decisions.

Selection Notes

Select this connector when a single-row female interface is required for 0.062-inch thick boards. Confirm that the 0.156-inch pitch aligns with the mating card edge finger spacing. Evaluate the low-profile form factor against available vertical clearance constraints in the enclosure design. Ensure solder termination methods match the manufacturing process capabilities.

Part Context

This component belongs to the EDAC 306 series of standard card edge connectors. The series offers various design options to tailor interconnect requirements. The 306-021 variant specifically denotes the contact count and physical dimensions within the broader product family, providing standardized solutions for edgeboard applications.

Replacement Considerations

Direct substitutes must match the 21-contact count, single-row female configuration, and 0.156-inch pitch. Verify compatibility with 0.062-inch board thickness and straight mounting orientation. Consult EDAC official equivalents lists for cross-referenced part numbers with identical mechanical and electrical specifications.
