Key Parameters

Substitute Part Grouping Explanation

Substitution of the ALFD29902DN-A-240V is based on the following critical parameters that must remain consistent:

• Manufacturer: IDEC (same manufacturer ensures design compatibility and mechanical fit)
• Form Factor: 30MM illuminated pushbutton configuration
• Voltage Rating: 240V operation
• Operation Type: Momentary action
• Contact Configuration: 2NC (two normally closed contacts)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement maintained)
• Moisture Sensitivity Level: 1 (Unlimited) (environmental handling unchanged)
• Packaging: Bulk format

The substitute part ALFD2QM402DNUA meets all these parameters and represents the active product line equivalent to the obsolete ALFD29902DN-A-240V.

Parameter Comparison

Engineering Selection Recommendations

The ALFD2QM402DNUA is the direct substitute for the obsolete ALFD29902DN-A-240V. Selection of this substitute part is based on:

• Product Status Alignment: The substitute is an active product, ensuring ongoing availability and manufacturer support
• Regulatory Compliance: Both parts maintain ROHS3 compliance and identical ECCN/HTSUS classifications
• Functional Equivalence: Identical electrical specifications (240V, 2NC contact configuration, momentary operation) and mechanical form factor (30MM illuminated pushbutton)
• Environmental Handling: Matching Moisture Sensitivity Level (1) ensures identical storage and handling requirements

The ALFD2QM402DNUA provides direct functional replacement with no design modifications required for existing applications.

Frequently Asked Questions (FAQ)

Q: Can the ALFD2QM402DNUA be used as a direct replacement for the ALFD29902DN-A-240V?
