Substitute Part Grouping Explanation

The substitute part ALFD248611DNUA is derived from the same base product number (ALFD248611) and maintains functional equivalence through identical electrical and mechanical specifications. Substitution is valid based on the following criteria:

• Identical 30mm form factor and pushbutton configuration
• Matching momentary contact operation (1NO1NC contact arrangement)
• Equivalent voltage rating (480V TR)
• Identical RoHS3 compliance status
• Matching MSL rating of 1 (Unlimited)
• Same ECCN and HTSUS classification

The primary distinction is product status: the substitute part is currently active in production, whereas the main part is obsolete.

Engineering Selection Recommendations

For applications currently using ALFD248611DN-A, the ALFD248611DNUA serves as the direct functional equivalent. Selection should be based on the following factors:

• Product Availability: ALFD248611DNUA is in active production with current inventory availability, whereas ALFD248611DN-A is obsolete with limited remaining stock.
• Compliance Continuity: Both parts maintain identical ROHS3 compliance and regulatory classification, ensuring no changes to system certifications or documentation.
• Packaging Considerations: ALFD248611DNUA is supplied in bulk packaging, which may affect procurement quantities and storage requirements compared to standard packaging.
• Electrical Equivalence: Identical contact configuration (1NO1NC), voltage rating (480V), and operational characteristics ensure direct substitution without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can ALFD248611DNUA be used as a direct replacement for ALFD248611DN-A?

A: Yes. Both parts share the same base product number and maintain identical electrical specifications, contact configuration, and compliance ratings. The substitute part is the active production equivalent of the obsolete part.

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

A: The primary difference is product status. ALFD248611DN-A is obsolete, while ALFD248611DNUA is currently in active production. The suffix variation indicates packaging and production configuration changes. Electrical and mechanical specifications remain equivalent.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical ROHS3 compliance, MSL rating, ECCN classification, and HTSUS coding. System certifications and regulatory documentation require no modification when substituting between these parts.

Q: Does packaging affect compatibility?

A: Packaging format (standard versus bulk) does not affect component compatibility or performance. Packaging differences impact procurement logistics and storage requirements only. The electrical and mechanical form factor remains identical.

Q: What contact configuration does this pushbutton switch provide?

A: Both parts provide 1NO1NC (one normally open, one normally closed) contact configuration in momentary operation at 480V rated voltage.
