857-018-454-107

Edgeboard Connectors Overview

The EDAC Inc. 857-018-454-107 is a high-temperature standard card edge connector receptacle designed for robust panel mount applications. It features a single row with 7 positions and a pitch of 3.96 mm (0.156 inches). The unit supports a board thickness of 1.57 mm and utilizes gold-plated copper alloy contacts for reliable signal transmission. Rated for 5 A current, it operates within a temperature range of -40°C to +125°C. The housing is constructed from Polyphenylene Sulfide (PPS), providing an insulation resistance of 5 GOhms. This right-angle component ensures secure vertical mating with card edge PCBs in demanding environments.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm plating type and material composition. Ensure compatibility with target PCB thickness of 1.57 mm before procurement. Confirm that the right-angle orientation meets mechanical layout requirements. Check for any recent product change notifications or RoHS compliance updates directly from the manufacturer's official channels prior to ordering.

Edgeboard Connectors Selection Notes

Select this component when high-temperature performance is critical, as indicated by the +125°C maximum rating. The single-row, 7-position layout suits low-pin-count applications where space is constrained. Verify that the 3.96 mm pitch matches the target card edge design. Consider the PPS housing material for superior chemical and thermal resistance compared to standard thermoplastics in harsh operating conditions.

Edgeboard Connectors Part Context

This part belongs to the EDAC 857 series, which specializes in high-temperature card edge connectors. The series is engineered for reliability in extreme environments, distinguishing it from standard industrial connectors. The 857 series typically employs advanced insulating materials like PPS to maintain structural integrity under elevated temperatures, making it suitable for specialized sectors beyond general consumer electronics.

Edgeboard Connectors Replacement Considerations

Consult official EDAC substitution guides for verified equivalents. Cross-reference pin counts, pitch dimensions, and termination styles to ensure mechanical fit. Verify that alternative parts meet or exceed the +125°C operating temperature requirement. Confirm that contact plating and current ratings are compatible with the existing circuit design.
