Overview
The EDAC Inc. 306-035-420-103 is a standard card edge connector receptacle featuring 70 positions with a 3.96 mm (0.156 inch) contact spacing. It utilizes a dual female configuration designed for non-specified board thicknesses, accommodating nominal PCB thickness of 1.57 mm (0.062 inch). The component employs tin-plated copper alloy contacts and a green insulator body. It supports panel mount installation with vertical orientation and solder pin termination.
Feature Summary
- Dual edge female connector design for secure mating with double-sided circuit boards
- Low profile insulator body construction to minimize overall assembly height
- Single centerline row arrangement maintaining consistent contact alignment
Applications
- Industrial control system interface modules
- Telecommunications equipment backplanes
- Computing hardware expansion slots
Procurement Notes
Verify the specific plating material against official datasheets, as distributor listings may inconsistently describe the finish as either tin or gold. Confirm that the 70-position count aligns with the dual-edge requirement rather than single-row specifications found in similar part numbers. Ensure the panel mount style matches the mechanical constraints of the target enclosure design before finalizing procurement orders.
Selection Notes
Select this component when a high-density connection with 70 positions is required for double-sided PCB applications. The 3.96 mm pitch offers robust signal separation compared to finer pitches. Verify compatibility with the target PCB thickness of 1.57 mm to ensure proper insertion depth and mechanical stability within the mounting structure.
Part Context
This part belongs to the EDAC 306 series of standard card edge connectors. The series provides reliable interconnection solutions for various electronic assemblies. The specific model number indicates the position count, series generation, and terminal configuration within the manufacturer's standardized product lineup.
Replacement Considerations
Cross-reference with EDAC 306-010-420-104 for single-row variants if dual-edge functionality is not required. Check EDAC 846-035-526-104 for high-temperature applications requiring DAP housing materials instead of standard thermoplastic polyester.
