Key Parameters

Substitute Part Grouping Explanation

Substitution of the ALFD29920DN-A-24V is based on the following critical parameters that must remain consistent:

• 30mm pushbutton form factor
• 24V operating voltage
• Illuminated pushbutton functionality
• Momentary operation
• ROHS3 compliance
• Moisture Sensitivity Level 1 (Unlimited)
• ECCN and HTSUS classification alignment

The identified substitute part maintains these core electrical and mechanical specifications, ensuring functional compatibility within the original application context.

Parameter Comparison

Engineering Selection Recommendations

The ALFD22220DNUA is the active equivalent for the obsolete ALFD29920DN-A-24V. Both components share identical voltage ratings, form factors, compliance certifications, and regulatory classifications. The substitute part is currently in active production status with confirmed inventory availability, making it suitable for direct replacement in applications requiring the original component specifications.

Selection of the ALFD22220DNUA is supported by:

• Matching 24V voltage specification
• Identical 30mm pushbutton form factor
• ROHS3 compliance alignment
• Equivalent moisture sensitivity rating
• Consistent ECCN and HTSUS classification
• Active product status ensuring long-term availability

Frequently Asked Questions (FAQ)

Q: Can the ALFD22220DNUA directly replace the ALFD29920DN-A-24V?

A: Yes. Both components meet the core substitution criteria: 30mm illuminated pushbutton design, 24V operation, ROHS3 compliance, and identical regulatory classifications. The substitute part is active and available.

Q: What is the significance of the 2NO contact configuration listed for the substitute?

A: The 2NO (Two Normally Open) designation specifies the electrical contact arrangement of the ALFD22220DNUA. This parameter must be verified against the original application requirements to ensure compatibility with the control circuit.

Q: Does the Amber illumination color of the substitute affect compatibility?

A: Illumination color is a functional characteristic that should be evaluated based on application requirements. If the original system requires a specific illumination color, this parameter must be confirmed before implementation.

Q: Why is the original part classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The ALFD22220DNUA represents the active equivalent maintained in current production.

Q: Are there inventory considerations for this substitution?

A: The ALFD22220DNUA is available in bulk packaging with confirmed stock. Procurement timelines and packaging requirements should be evaluated based on application needs.
