Key Parameters

Substitute Part Grouping Explanation

The ALD21102DNUA qualifies as a direct substitute for the ALD29902DN-A-12V based on the following alignment of critical parameters:

• Manufacturer: Both parts are manufactured by IDEC
• Physical Form Factor: Both are 30mm pushbutton switches
• Operation Mode: Both provide illuminated momentary operation
• Rated Voltage: Both operate at 12V
• Contact Configuration: Both feature 2NC (two normally closed) contacts with amber illumination
• Regulatory Compliance: Both maintain ROHS3 compliance and identical ECCN/HTSUS classifications
• Moisture Sensitivity: Both carry MSL rating of 1 (Unlimited)

The substitution is valid across all specified electrical and mechanical parameters. The transition from obsolete to active product status ensures continued availability and supply chain reliability.

Parameter Comparison

Engineering Selection Recommendations

The ALD21102DNUA is the direct equivalent for the obsolete ALD29902DN-A-12V. Selection of the substitute part is based on:

• Functional Equivalence: All electrical and mechanical parameters align without deviation
• Regulatory Compliance: Both parts maintain identical ROHS3 compliance status and export classifications
• Supply Chain Continuity: The substitute part maintains active product status, ensuring long-term availability and procurement reliability
• Certification Alignment: Identical ECCN and HTSUS classifications confirm regulatory equivalence for import/export and tariff purposes

No additional testing or qualification is required when transitioning from the obsolete part to its active equivalent, provided the application parameters remain within the specified 12V, 30mm illuminated momentary pushbutton requirements.

Frequently Asked Questions (FAQ)

Q: Can ALD21102DNUA be used as a direct replacement for ALD29902DN-A-12V in existing designs?

A: Yes. Both parts share identical electrical ratings (12V), mechanical form factor (30MM), contact configuration (2NC), and illumination characteristics (amber). All regulatory certifications and compliance standards are equivalent.

Q: What is the primary reason for substitution?

A: The ALD29902DN-A-12V is classified as obsolete. The ALD21102DNUA provides functional equivalence while maintaining active product status and ensuring continued supply availability.

Q: Are there packaging differences between these parts?

A: The ALD21102DNUA is supplied in bulk packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 compliant with identical ECCN (EAR99) and HTSUS (8536.50.9035) classifications. Moisture sensitivity levels are identical at MSL 1 (Unlimited).

Q: Is the base product number relevant for substitution?

A: The ALD21102 base product number for the substitute indicates the core product line. This designation confirms the part belongs to the same IDEC 30mm illuminated pushbutton switch family and reinforces functional equivalence.
