Overview
The EDAC Inc. 306-029-521-108 is a dual-edge card edge connector designed for through-hole mounting. It features 58 positions with female contacts arranged in two rows of 29 pins each. The contact spacing is 0.156 inches (3.96 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Contacts are made of copper alloy with gold plating to ensure reliable signal transmission. The insulator body is constructed from thermoplastic polyester and is colored green.
Feature Summary
- Dual-edge configuration with female contacts for secure board insertion
- Gold-plated copper alloy contacts for enhanced conductivity and corrosion resistance
- Low-profile insulator body design suitable for space-constrained applications
- Through-hole termination method for robust mechanical stability
Applications
- Industrial control systems requiring reliable I/O connections
- Telecommunications equipment interface modules
- Consumer electronics internal board-to-board interconnects
- Medical device instrumentation circuitry
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current datasheet to confirm contact plating thickness and insulator color specifications. Ensure that the procurement documentation explicitly references the full part number 306-029-521-108 to avoid confusion with similar series variants. Confirm RoHS compliance status as per the latest regulatory updates provided by EDAC Inc. prior to finalizing purchase orders.
Selection Notes
Select this component when a dual-edge connector with 0.156-inch spacing is required for PCBs with a nominal thickness of 0.062 inches. The 58-position count fits standard form factors requiring this pin density. Verify that the application environment does not exceed the operating temperature range specified in the official documentation. Consider the low-profile body height if vertical clearance on the assembly is limited.
Part Context
This part belongs to the EDAC 306 series, which focuses on card edge connectors with 0.156-inch contact spacing. The series offers various position counts and termination styles. The 306-029-521-108 specifically denotes the dual-edge, female contact variant with gold plating. It is distinct from single-edge or different spacing models within the broader EDAC portfolio.
Replacement Considerations
Direct substitutes must match the 0.156-inch spacing, 58-position count, and dual-edge female configuration. Verify that any alternative part supports the same 0.062-inch board thickness and through-hole mounting style. Cross-reference the flange dimensions and insulator material properties to ensure mechanical compatibility.
