Key Parameters

Substitute Part Grouping Explanation

The substitute part ALFD248602DNUA is qualified as a direct equivalent based on the following criteria:

• Identical manufacturer (IDEC)
• Shared base product number (ALFD248602)
• Matching functional classification (30mm pushbutton switch)
• Identical RoHS3 compliance status
• Identical Moisture Sensitivity Level (MSL 1)
• Identical ECCN and HTSUS classifications
• Active product status with current manufacturer support

The substitution is valid across these controlled parameters. The substitute part differs in packaging format (Bulk versus standard packaging) and includes an extended part number suffix (DNUA) that designates specific electrical configuration (480V, 2NC contact arrangement, ambient temperature rating).

Parameter Comparison

Engineering Selection Recommendations

The ALFD248602DNUA is the direct substitute for the obsolete ALFD248602DN-A. Selection of this substitute is supported by:

• Identical compliance certifications (ROHS3, EAR99, HTSUS classification)
• Matching environmental specifications (MSL 1)
• Active product status ensuring continued availability and manufacturer technical support
• Shared base product architecture and electrical classification

The transition from the obsolete part number to the active substitute part number is appropriate for both replacement applications and new designs requiring 30mm illuminated pushbutton switch functionality within the specified electrical and environmental parameters.

Frequently Asked Questions (FAQ)

Q: Can ALFD248602DNUA directly replace ALFD248602DN-A in existing applications?

A: Yes. Both parts share identical RoHS3 compliance, MSL rating, and ECCN/HTSUS classifications. The substitute is manufactured by the same supplier (IDEC) and is based on the same product platform (ALFD248602 base number). The electrical configuration (480V, 2NC, ambient rating) specified in the substitute part number must match the original application requirements.

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

A: ALFD248602DN-A is the obsolete designation. ALFD248602DNUA is the active equivalent with an extended suffix (UA) that specifies the electrical configuration. Both parts are 30mm illuminated pushbutton switches from IDEC with identical compliance and environmental ratings.

Q: Are there packaging differences between these parts?

A: The main part uses standard packaging, while the substitute (ALFD248602DNUA) is supplied in Bulk packaging. Bulk packaging does not affect component functionality or electrical performance; it only impacts order quantity and handling logistics.

Q: What compliance standards apply to both parts?

A: Both parts are ROHS3 compliant, classified under ECCN EAR99, and assigned HTSUS code 8536.50.9035. Both have MSL rating of 1 (Unlimited moisture sensitivity), indicating no moisture-related storage restrictions.

Q: Why is the original part listed as obsolete?

A: Product obsolescence typically reflects manufacturer discontinuation of a specific part number designation. The active substitute ALFD248602DNUA provides equivalent functionality and maintains all required compliance certifications, making it the appropriate selection for ongoing applications.
