Overview
The EDAC Inc. 306-025-421-158 is a standard card edge connector from the 306 series, designed for reliable signal transmission in electronic assemblies. It features 25 positions arranged in a single row with a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts to ensure low contact resistance and durability. Designed for panel mount installation at a vertical angle, it accommodates a board thickness of 1.57 mm. The thermoplastic insulator provides structural integrity, while the component supports a current rating of 5 A and operates within a temperature range of -40°C to +105°C.
Feature Summary
- Vertical panel mount configuration for secure mechanical integration
- Gold-plated copper alloy contacts for enhanced conductivity
- Single-row design with 25 positions for compact layout
- Thermoplastic housing for durable insulation
Applications
- Medical interconnect solutions
- Agricultural technology equipment
- Industrial control panels
Procurement Notes
Verify the specific ordering suffix against the official EDAC datasheet to confirm exact plating thickness, material grade, and locking features. Ensure compatibility with the target PCB edge thickness of 1.57 mm before procurement. Confirm that the vertical panel mount style aligns with the enclosure design requirements. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability.
Selection Notes
Select this component when a vertical, panel-mount card edge interface is required for single-row applications. The 3.96 mm pitch suits designs needing robust spacing between contacts. Verify that the 5 A current rating meets the circuit load requirements. Ensure the operating temperature range of -40°C to +105°C covers the environmental conditions of the intended application site.
Part Context
This component belongs to the EDAC 306 series of standard card edge connectors. The series is characterized by its use in demanding environments, including medical and agricultural sectors. The 306 series typically offers panel mount options with vertical orientations, distinguishing it from surface-mount or through-hole variants found in other EDAC product lines.
Replacement Considerations
Direct substitutes include EDAC part numbers such as 306-025-520-107 and 306-025-500-112, which share similar series characteristics. Verify pin count, pitch, and mounting style compatibility before substitution.
