Key Parameters

Substitute Part Grouping Explanation

Substitution of the ALFD29911DN-A-12V is determined by the following critical parameters:

• 30mm form factor and mechanical envelope
• 12V illumination voltage requirement
• Pushbutton switch functionality with momentary operation
• ROHS3 compliance certification
• Moisture Sensitivity Level 1 rating
• ECCN and HTSUS classification alignment

The substitute part ALFD21111DNUA meets these criteria through identical mechanical specifications, voltage compatibility, and regulatory compliance status. Both components share the same manufacturer (IDEC), classification codes, and environmental compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

The ALFD21111DNUA is the direct substitute for the obsolete ALFD29911DN-A-12V. Selection is based on:

• Identical 30mm mechanical form factor ensuring direct mounting compatibility
• Matching 12V voltage specification for illumination circuits
• Active product status of the substitute part, ensuring continued availability and supply chain reliability
• Equivalent ROHS3 compliance and MSL 1 rating, maintaining environmental and reliability standards
• Identical regulatory classification (ECCN EAR99, HTSUS 8536.50.9035)

The transition from the obsolete ALFD29911DN-A-12V to the active ALFD21111DNUA presents no technical barriers to implementation in existing or new applications.

Frequently Asked Questions (FAQ)

Q: Can ALFD21111DNUA directly replace ALFD29911DN-A-12V in existing assemblies?
