Frequently Asked Questions (FAQ)

Q: Can the ASD3K20NU-RC be used as a direct replacement for the ASD3K20N-RC?

A: Yes. Both parts share the same base product number (ASD3), identical circuit configuration (DPST-NO), 3-position switching function, panel mount interface, and screw terminal termination. The substitute is designed for direct installation in applications originally specified for the main part.

Q: What is the primary difference between these two parts?

A: The main difference is product status. The ASD3K20N-RC is obsolete, while the ASD3K20NU-RC is active and currently manufactured by IDEC. Both maintain equivalent electrical and mechanical specifications.

Q: Are there packaging differences between the main part and substitute?

A: The main part packaging is listed as "-" (not specified), while the substitute is supplied in Bulk packaging. This does not affect functional compatibility; packaging differences relate only to order quantity and delivery format.

Q: Do both parts meet current compliance requirements?

A: Yes. Both the ASD3K20N-RC and ASD3K20NU-RC are ROHS3 compliant and carry MSL Level 1 rating, meeting current regulatory standards for electronic component procurement and use.

Q: What electrical specifications must be matched for substitution?

A: Critical parameters for substitution include circuit configuration (DPST-NO), number of positions (3), current ratings (10A AC / 8A DC), voltage ratings (110V AC / 24V DC), and contact material (Silver). The substitute maintains all these specifications.

Q: Are there any mechanical interface considerations?

A: Both parts feature identical panel mount configuration with 30.50mm circular cutout dimensions and 53.00mm depth behind flange. Screw terminal termination is consistent across both parts, ensuring mechanical and electrical interface compatibility.
