Key Parameters

Substitute Part Grouping Explanation

The ABFD402NUS qualifies as a direct substitute based on the following alignment of critical parameters:

• Manufacturer: Both parts are manufactured by IDEC
• Product Category: Both are pushbutton switches with 30mm form factor
• RoHS Compliance: Both meet ROHS3 Compliant standards
• Moisture Sensitivity Level: Both rated at MSL 1 (Unlimited)
• Regulatory Classification: Both assigned ECCN EAR99 and HTSUS 8536.50.9035
• Base Product Number: ABFD402NUS shares the common base product number ABFD402 with the original part

The primary distinction is product status: ABFD402NUS is Active, providing current availability and ongoing manufacturer support, whereas ABFD402N-S is Obsolete.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using ABFD402N-S, the ABFD402NUS is the appropriate substitute. Both components share identical compliance certifications (ROHS3), regulatory classifications (EAR99, HTSUS 8536.50.9035), and environmental ratings (MSL 1). The transition from an obsolete part to an active production part ensures access to current inventory and manufacturer support. The ABFD402NUS is available in bulk packaging, suitable for production and replacement stock applications.

Frequently Asked Questions (FAQ)

Q: What makes ABFD402NUS a valid substitute for ABFD402N-S?

A: Both parts are IDEC 30mm pushbutton switches with identical RoHS3 compliance, MSL 1 rating, and regulatory classifications. The substitute shares the same base product number (ABFD402) and maintains all critical electrical and environmental parameters.

Q: Why is ABFD402N-S listed as obsolete?

A: Obsolete status indicates the part is no longer in active production. ABFD402NUS, the active equivalent, is the recommended replacement for new applications and ongoing support.

Q: Are there packaging differences between these parts?

A: ABFD402N-S packaging is unspecified in available documentation. ABFD402NUS is supplied in bulk packaging, standard for production and replacement inventory.

Q: Do both parts meet the same compliance standards?

A: Yes. Both ABFD402N-S and ABFD402NUS are ROHS3 compliant with MSL 1 (Unlimited) rating and share identical ECCN and HTSUS classifications.

Q: Can ABFD402NUS be used as a direct replacement in existing installations?

A: Yes. The electrical and mechanical parameters are equivalent, and both components meet identical compliance requirements, supporting direct substitution in applications originally specified for ABFD402N-S.
