Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability status and regional distribution restrictions.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with a 3.96 mm pitch is required for vertical panel integration. The 5 A current rating makes it suitable for power distribution within modular electronic assemblies. Confirm that the application environment supports the specified operating temperature range and insulation resistance requirements for long-term reliability.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which provides various mounting options and row configurations for card edge applications. The series is characterized by its standardized 3.96 mm pitch and robust construction using thermoplastic housings. Components in this family are designed to accept polarizing keys for precise alignment during assembly.

Edgeboard Connectors Replacement Considerations

Compatible substitutes within the same series include models such as 305-042-521-503 and 305-042-521-512. Verify that alternative part numbers maintain identical electrical ratings, physical dimensions, and termination styles to ensure direct interchangeability without redesigning the host circuit board.
