Overview
The EDAC Inc. 306-035-421-107 is a standard card edge connector from the 306 series, designed for panel mount applications. It features a dual female configuration with 70 positions and a contact spacing of 0.156 inches (3.96 mm). The component utilizes solder tail termination and gold plating on copper alloy contacts to ensure reliable electrical connections. It supports PCB thicknesses ranging from 0.054 to 0.070 inches (1.37 mm to 1.78 mm) and operates within a temperature range of -40°C to 105°C.
Feature Summary
- Dual female card edge design for robust signal transmission
- Gold-plated copper alloy contacts for corrosion resistance
- Panel mount installation with vertical orientation
- Thermoplastic polyester insulation housing
Applications
- Industrial control systems requiring high-density interconnects
- Telecommunications equipment backplanes
- Test and measurement instrumentation panels
- Automotive electronic modules
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to confirm contact plating and flange characteristics. Ensure compatibility with the target PCB thickness and mounting hole specifications before procurement. Confirm RoHS compliance status if required by project regulations. Cross-reference the Mouser or DigiKey part numbers for accurate sourcing channels.
Selection Notes
Select this connector when a dual-sided card edge interface with 70 positions is required. The 3.96 mm pitch accommodates standard board layouts while providing sufficient spacing for high-current applications. Verify that the panel mount style aligns with the mechanical enclosure design. Consider the operating temperature range and insulation material properties for environmental suitability.
Part Context
This component belongs to the EDAC 306 series of standard card edge connectors. The series offers various position counts and termination styles to support diverse electronic assembly needs. The 306-035-421-107 variant specifically addresses requirements for dual female configurations with solder tail termination, providing a standardized solution for panel-mounted interconnects in professional electronics.
Replacement Considerations
Compatible substitutes include other EDAC 306 series parts with matching 70-position dual female configurations and 3.96 mm pitch. Verify mechanical dimensions and pinout alignment before substitution. Alternative manufacturers may offer similar connectors but require thorough validation of electrical ratings and physical fit.
