Frequently Asked Questions (FAQ)

Q: Can the ASD33K22NU-310 directly replace the ASD33K22N-310 in existing applications?

A: Yes. Both parts share identical circuit configuration (4PST-2NO/2NC), electrical ratings (10A AC / 110V, 8A DC / 24V), mechanical dimensions, and mounting specifications. The substitute is a direct functional equivalent.

Q: What is the difference between the two part numbers?

A: The primary difference is product status. The ASD33K22N-310 is obsolete, while the ASD33K22NU-310 is an active production part from the same manufacturer. The suffix change reflects the active status and current availability of the substitute.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain ROHS3 compliance, identical MSL ratings (1 - Unlimited), and equivalent environmental specifications (IP54, -25°C to 50°C operating range).

Q: What packaging is available for the substitute part?

A: The ASD33K22NU-310 is supplied in bulk packaging, suitable for production and maintenance applications.

Q: Are the panel cutout dimensions identical?

A: Yes. Both parts require a circular 30.50mm diameter panel opening and have identical depth behind flange (76.00mm), ensuring mechanical compatibility in existing panel installations.

Q: Can I use the substitute part for new designs?

A: Yes. The ASD33K22NU-310 is an active production part with full manufacturer support, making it suitable for both replacement and new design applications.
