Inventory Availability: The ASD31K02NU is currently in stock with comparable inventory levels, supporting immediate procurement for replacement applications.

Frequently Asked Questions (FAQ)

Q: Can the ASD31K02NU directly replace the ASD31K02N in existing installations?

A: Yes. The ASD31K02NU is electrically and mechanically equivalent to the ASD31K02N across all specified parameters, including circuit configuration, current and voltage ratings, actuator type, mounting dimensions, and termination style. Panel cutout and depth behind flange dimensions are identical, enabling direct installation without mechanical modification.

Q: What is the difference between the ASD31K02N and ASD31K02NU?

A: The primary difference is product status. The ASD31K02N is obsolete, while the ASD31K02NU is an active product. Both components share identical electrical specifications, mechanical dimensions, contact materials, and regulatory compliance ratings. The ASD31K02NU represents the current production equivalent.

Q: Are there packaging differences between these parts?

A: The ASD31K02N packaging designation is not specified in available documentation. The ASD31K02NU is supplied in bulk packaging. For specific packaging requirements or custom configurations, contact the manufacturer directly.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the ASD31K02N and ASD31K02NU are ROHS3 compliant with identical Moisture Sensitivity Level ratings of 1 (Unlimited), confirming equivalent regulatory status.

Q: What is the mechanical life expectancy for the substitute part?

A: The ASD31K02N is rated for 500,000 mechanical cycles. Equivalent mechanical life specifications for the ASD31K02NU should be confirmed with IDEC technical documentation or the component supplier.
