Key Parameters

Substitute Part Grouping Explanation

Substitution of the ALFD29902DN-A-24V is determined by the following critical parameters:

• 30mm form factor and mechanical envelope
• 24V operating voltage
• Illuminated pushbutton functionality with momentary contact operation
• ROHS3 compliance requirement
• Moisture Sensitivity Level 1 classification

The substitute part ALFD22202DNUA meets these criteria through identical voltage rating, form factor, contact configuration (2NC momentary), and compliance certifications. Both parts share the same HTSUS classification and ECCN designation, confirming functional and regulatory equivalence.

Parameter Comparison

Engineering Selection Recommendations

The ALFD22202DNUA is the direct substitute for the obsolete ALFD29902DN-A-24V. Selection is based on:

• Identical voltage specification (24V)
• Matching form factor (30mm illuminated pushbutton)
• Equivalent contact operation (momentary)
• Active product status ensuring continued availability
• Full ROHS3 compliance and regulatory alignment
• Identical moisture sensitivity classification and export control designation

The substitute part maintains all critical electrical and mechanical parameters required for direct replacement in existing applications.

Frequently Asked Questions (FAQ)
