Overview
The EDAC Inc. 306-025-400-104 is a standard card edge connector from the 306 series, designed for panel mount vertical installation. It features a dual female configuration with 50 positions arranged in two rows of 25 contacts each. The connector utilizes a 0.156-inch (3.96 mm) contact spacing and accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Constructed with copper alloy contacts featuring gold plating and a thermoplastic insulator body, it supports a current rating of 5 A per contact. The unit operates within a temperature range of -40°C to +105°C and provides an insulation resistance of 5 GOhms.
Feature Summary
- Vertical panel mount design with low-profile insulator body
- Dual edge acceptance for non-specified PCBs
- Gold-plated copper alloy cantilever contacts
- Thermoplastic housing material
Applications
- Industrial control system interconnections
- Panel-mounted electronic module interfaces
- High-density signal routing applications
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official 306 Series Ordering Guide to ensure compatibility with required board thickness and mounting hardware. Confirm that the green color variant matches the design specification. Cross-reference the RoHS compliance status with current regulatory requirements for the target market before finalizing procurement orders.
Selection Notes
Select this component when a vertical, panel-mount solution is required for double-sided edge cards. Ensure the host PCB thickness falls within the specified 1.37mm to 1.78mm range. Consider the 3.96mm pitch for spacing constraints and verify that the 5A current rating meets the electrical load requirements of the application circuitry.
Part Context
This part belongs to the EDAC 306 series of standard card edge connectors. The series is characterized by its robust construction and suitability for high-reliability applications. Similar parts in the family vary by position count, pitch, and mounting style, but share common design principles regarding contact material and insulator durability.
Replacement Considerations
Direct substitutes include other EDAC 306 series variants with matching 50-position dual-row configurations. Verify mechanical dimensions and flange characteristics to ensure fitment. Alternative manufacturers may offer comparable specs but require thorough validation of contact geometry and thermal ratings.
