Key Parameters

Substitute Part Grouping Explanation

Substitution for the ALD39902DN-A-12V is based on the following critical parameters:

• Manufacturer: IDEC (same manufacturer ensures design compatibility)
• Product Category: Pushbutton Switch
• Voltage Rating: 12V operation
• RoHS Compliance: ROHS3 Compliant (regulatory alignment)
• Moisture Sensitivity Level: 1 (Unlimited) (environmental tolerance match)
• ECCN/HTSUS Classification: Identical trade classification codes

The substitute part ALD31102DNUA meets these core criteria while offering active product status and current manufacturing availability.

Parameter Comparison

Engineering Selection Recommendations

The ALD31102DNUA serves as the direct substitute for the obsolete ALD39902DN-A-12V based on:

• Regulatory Compliance: Both parts maintain ROHS3 compliance and identical trade classification codes (ECCN: EAR99, HTSUS: 8536.50.9035)
• Environmental Specifications: Matching Moisture Sensitivity Level 1 ensures equivalent environmental tolerance
• Operational Voltage: Both operate at 12V, ensuring direct electrical compatibility
• Manufacturer Continuity: IDEC manufacture ensures design and quality standards alignment
• Active Status: The substitute part maintains active production status, ensuring long-term availability and supply chain stability

The primary design difference is the increased button diameter (40mm versus 30mm), which requires mechanical integration assessment for panel mounting applications.

Frequently Asked Questions (FAQ)

Q: Can ALD31102DNUA directly replace ALD39902DN-A-12V in existing assemblies?

A: Electrical and compliance specifications are equivalent. Mechanical integration must be evaluated, as the substitute features a 40mm button diameter compared to the original 30mm form factor. Panel cutout and mounting bracket modifications may be required.

Q: Are the RoHS and regulatory certifications identical?

A: Yes. Both parts are ROHS3 compliant with matching ECCN (EAR99) and HTSUS (8536.50.9035) classifications, ensuring regulatory equivalence for export and procurement purposes.

Q: What is the significance of the "Active" product status for ALD31102DNUA?

A: Active status indicates current manufacturing and ongoing availability from IDEC. This ensures supply chain continuity and access to technical documentation, whereas the original ALD39902DN-A-12V is obsolete and subject to inventory depletion.

Q: Are there differences in packaging between these parts?

A: The substitute part is supplied in Bulk packaging. Original packaging specifications for ALD39902DN-A-12V were not provided. Confirm packaging requirements for your procurement and assembly processes.

Q: Do both parts share the same moisture sensitivity rating?

A: Yes. Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating equivalent environmental tolerance and storage requirements.
