Overview
The EDAC Inc. 306-025-520-104 is a standard card edge connector from the 306 series, designed for panel mount vertical installation. It features 50 positions with a 0.156-inch (3.96 mm) pitch and gold-plated copper alloy contacts. The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). It operates within a temperature range of -40°C to +105°C and utilizes a thermoplastic insulator body.
Feature Summary
- Accepts PCBs with a nominal thickness of 0.062 inches (1.57 mm)
- Features a low-profile insulator body design
- Utilizes gold-plated copper alloy contacts for reliable connectivity
Applications
- Panel-mounted electronic assemblies requiring vertical interconnection
- Industrial control systems utilizing dual-edge card edge modules
- Test and measurement equipment interfaces
Procurement Notes
Verify the specific color variant against project requirements, as the 306 series includes green and black options. Confirm that the target PCB thickness aligns with the 0.062-inch nominal specification to ensure proper mechanical retention. Check current availability status, as distribution channels may report restricted supply or regional sales limitations for this component.
Selection Notes
Select this model when a single-centerline row configuration with a 3.96 mm pitch is required for panel mounting. Ensure the application environment remains within the specified -40°C to +105°C operating range. Verify compatibility with dual-edge card edge designs, as the connector is engineered specifically for this board type rather than single-edge variants.
Part Context
This component 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. The 306 series offers various position counts and color options, providing flexibility for different panel integration needs while maintaining consistent electrical performance standards across the family.
Replacement Considerations
The 356-025-520-104 is a documented substitute within the same manufacturer lineup. Both parts share identical 50-position counts, 3.96 mm spacing, and dual-edge female contact configurations. Verify dimensional compatibility before substitution, as series variations may exist in housing height or flange specifications.
