Parameter Comparison

Engineering Selection Recommendations

The ASD31K22NU-310 is the direct substitute for the obsolete ASD31K22N-310. Both components share the same base product number (ASD31) and are manufactured by IDEC. The substitute maintains ROHS3 compliance and MSL rating 1 classification, ensuring regulatory alignment with the original component.

The primary advantage of selecting ASD31K22NU-310 is its active product status, providing assured availability and supply chain continuity. The ECCN classification change from OBSOLETE to EAR99 reflects the active status of the substitute part and does not impact functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can ASD31K22NU-310 directly replace ASD31K22N-310 in existing installations?

A: Yes. Both components share identical electrical specifications (4PST-2NO/2NC, 10A AC/8A DC, 110V AC/24V DC), mechanical mounting characteristics (panel mount, screw terminal, 30.50mm circular cutout), and regulatory compliance (ROHS3, MSL 1). The substitute is functionally equivalent for all applications requiring the original part.

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

A: The primary difference is product status. ASD31K22N-310 is obsolete, while ASD31K22NU-310 is active. Both are manufactured by IDEC under the same base product number (ASD31) and maintain identical functional and mechanical specifications.

Q: Are there packaging differences between these parts?

A: The main part packaging is listed as "-" (not specified), while the substitute is supplied in Bulk packaging. This represents a change in supply format only and does not affect component functionality or performance.

Q: Does the ECCN classification change affect procurement or use?

A: The ECCN change from OBSOLETE to EAR99 reflects the active status of the substitute part. EAR99 classification is standard for commercial electronic components and does not impose additional restrictions on procurement or use compared to the original part.

Q: What inventory status should be expected?

A: The substitute part ASD31K22NU-310 has 1063 pieces in stock as new original inventory, providing reliable availability for immediate procurement needs.
