Edgeboard Connectors Procurement Notes

Verify RoHS compliance status through official manufacturer documentation prior to integration. Confirm that the specific ordering suffix matches the required contact tail dimensions and mounting style. Ensure compatibility with existing polarizing key requirements for the target assembly. Cross-reference datasheet specifications against environmental constraints to validate operational suitability.

Edgeboard Connectors Selection Notes

Select this component when a 72-position dual-edge interface is required with 3.96 mm pitch. Consider the 5 A current rating and -40°C to +105°C temperature range for application viability. Evaluate the thermoplastic polyester material properties against chemical exposure risks. Verify PCB thickness tolerance aligns with the specified 1.57 mm acceptance criteria for proper mechanical engagement.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series, which provides standardized card edge connectors for various industrial and commercial applications. The series offers multiple position counts and mounting options, maintaining consistent electrical performance characteristics across variants. The 305-072-520-508 specifically addresses high-density connection needs with its 72-position configuration.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the 305 series include parts with identical pin counts and spacing, such as 305-072-520-204 or 305-072-521-201, provided mounting styles match. Verify that alternative part numbers maintain the same 3.96 mm pitch and 5 A rating. Ensure physical dimensions and polarizing key compatibility are preserved during substitution.
