- Medical device internal circuitry
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct plating and termination specifications. Confirm that the required PCB thickness falls within the specified range of 0.054 to 0.070 inches. Check for RoHS compliance status if environmental regulations apply to your assembly process. Ensure compatibility with existing panel mounting hardware and soldering profiles.
Selection Notes
Select this component when a dual-edge female connector with 68 positions is required. The 0.156-inch spacing suits applications where higher current capacity or robust mechanical connection is needed compared to finer pitches. Tin plating offers a cost-effective solution for general-purpose use. Verify that the panel mount style aligns with the enclosure design constraints and available mounting space.
Part Context
This part belongs to the EDAC 306 series, which provides a range of card edge connectors for various industrial and commercial applications. The series is known for its reliability and standardized dimensions. The 306-034-420-178 specifically addresses needs for medium-density connections with dual-edge access, fitting into broader system architectures requiring secure and durable electrical interfaces.
Replacement Considerations
Direct substitutes may include other 68-position dual-edge female connectors with identical 0.156-inch spacing and panel mount requirements. Verify mechanical footprint and pinout compatibility before substitution. Alternative plating options like gold may be considered for enhanced longevity in high-cycle applications.
