Overview
The EDAC Inc. part number 306-025-420-108 is a standard card edge connector from the 306 series, designed for vertical panel mount applications. It features a dual female configuration with 50 positions arranged in two rows. The connector utilizes a 0.156-inch (3.96 mm) pitch and accommodates board thicknesses of 1.57 mm. Contacts are constructed from copper alloy with gold plating to ensure reliable signal transmission. The housing is made of thermoplastic polyester, providing durability and insulation. This component supports solder pin termination and operates within a temperature range of -40°C to +105°C.
Feature Summary
- Dual female contact configuration for secure card edge mating
- Vertical panel mount installation style for structural stability
- Gold-plated copper alloy contacts for corrosion resistance
- Thermoplastic polyester housing for high-temperature performance
Applications
- Industrial control systems requiring robust interconnects
- Telecommunications equipment backplanes
- Test and measurement instrumentation modules
- Automotive electronic control units
Procurement Notes
Verify the specific ordering suffix against the official EDAC datasheet to confirm mechanical dimensions and contact plating specifications. Ensure compatibility with the target PCB card thickness of 1.57 mm before procurement. Confirm that the vertical panel mount orientation aligns with the system enclosure design requirements. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.
Selection Notes
Select this connector when a dual-row, 50-position interface is required for vertical mounting. The 0.156-inch pitch allows for higher density compared to standard 0.100-inch options while maintaining spacing. Consider the gold plating for environments where oxidation resistance is critical. Evaluate the thermoplastic polyester material properties against the operational temperature extremes of the application.
Part Context
This component belongs to the EDAC 306 series of standard card edge connectors. The series offers various position counts and mounting styles to suit different circuit board designs. The 306 series is characterized by its reliability in harsh environments and compliance with industry standards for interconnect devices. It serves as a fundamental building block for modular electronic systems.
Replacement Considerations
Consult the official EDAC cross-reference documentation for verified substitute part numbers. Ensure any replacement maintains the same 50-position count, 0.156-inch pitch, and dual female configuration. Verify that alternative parts support the same vertical panel mount style and compatible board thickness.
