Overview
The EDAC Inc. 306-021-521-178 is a dual-edge female card edge connector designed for panel and through-hole mounting. It features 42 positions arranged in two rows with a 0.156-inch (3.96mm) spacing. The contacts are made of copper alloy with a gold finish, utilizing a cantilever spring design. The housing is green thermoplastic polyester, rated for operation between -40°C and +105°C. It supports card thicknesses from 0.054 to 0.070 inches and includes flange features for secure installation.
Feature Summary
- Dual-edge female contact configuration with cantilever spring terminals
- Panel mount and through-hole termination options
- Gold-plated copper alloy contacts for reliable signal transmission
- Thermoplastic polyester insulation housing
Applications
- Industrial control systems
- Telecommunications equipment
- Test and measurement instruments
Procurement Notes
Verify the specific part number against official EDAC documentation to ensure compatibility with required card thickness and mounting constraints. Confirm that the gold plating specification meets the application's conductivity requirements. Check for RoHS compliance status if environmental regulations apply. Ensure the selected variant matches the exact pin count and spacing needed for the target PCB layout.
Selection Notes
Select this component when a robust dual-edge connection is required for thicker cards within the specified thickness range. Consider the 0.156-inch pitch for board layout planning. Evaluate the thermal rating of +105°C against the operating environment. Verify that the panel mount flange features align with the mechanical enclosure design. Compare against similar series parts if different row counts or pitches are needed.
Part Context
This connector belongs to the EDAC 306 Series, which offers various configurations for card edge applications. The series provides multiple mounting styles and contact options. The 306-021-521-178 specifically addresses needs for higher position counts with dual-edge access. It shares common material properties with other parts in the family but differs in pin count and specific mechanical features.
Replacement Considerations
Consult the EDAC 306, 316, and 356 Series Ordering Guide for potential substitutes. Verify that any replacement part maintains the same 0.156-inch pitch and 42-position count. Ensure mechanical dimensions and mounting hole patterns are compatible. Cross-reference specifications for current rating and temperature range.
