Substitute Part Grouping Explanation

The AOFD402NUS qualifies as a direct substitute for the AOFD402N-S based on the following criteria:

• Identical manufacturer (IDEC)
• Matching product category (Pushbutton Switch)
• Consistent physical form factor (30mm main body, 65mm depth)
• Identical electrical contact configuration (2NC - two normally closed contacts)
• Matching RoHS3 compliance status
• Identical Moisture Sensitivity Level (MSL 1)
• Identical ECCN and HTSUS classifications

The primary distinction is product status: AOFD402N-S is obsolete, while AOFD402NUS maintains active status with current manufacturer support.

Parameter Comparison

Engineering Selection Recommendations

The AOFD402NUS is the appropriate substitute for the obsolete AOFD402N-S. Both components share identical compliance certifications (ROHS3, EAR99, HTSUS 8536.50.9035) and environmental ratings (MSL 1). The AOFD402NUS maintains active product status, ensuring availability and manufacturer technical support. Selection of the substitute part eliminates obsolescence risk while preserving electrical and mechanical compatibility within the 30mm pushbutton switch category.

Frequently Asked Questions (FAQ)

Q: Can AOFD402NUS directly replace AOFD402N-S in existing installations?

A: Yes. Both components are 30mm IDEC pushbutton switches with identical RoHS3 compliance, MSL ratings, and trade classifications. The AOFD402NUS maintains the same form factor and contact configuration, supporting direct substitution.

Q: What is the significance of the product status difference?

A: AOFD402N-S is classified as obsolete, indicating discontinued manufacturing and limited availability. AOFD402NUS is active, ensuring continued production, inventory availability, and manufacturer technical support.

Q: Are there packaging differences between these parts?

A: Both components are supplied in bulk packaging. No packaging format change is required for substitution.

Q: Do the compliance ratings differ between the main part and substitute?

A: No. Both parts maintain identical RoHS3 compliance, EAR99 ECCN classification, and HTSUS code 8536.50.9035. Moisture Sensitivity Level is identical at MSL 1 (Unlimited).

Q: What parameters determine substitution eligibility for IDEC 30mm pushbutton switches?

A: Substitution is determined by manufacturer (IDEC), product type (Pushbutton Switch), physical size (30mm), contact configuration, and compliance certifications (RoHS3, ECCN, HTSUS). All these parameters are identical between AOFD402N-S and AOFD402NUS.
