Key Parameters

Substitute Part Grouping Explanation

Substitution for the ALD29902DN-A-6V is determined by the following critical parameters:

• 30mm form factor (mechanical compatibility)
• 6V operating voltage
• Illuminated pushbutton functionality with momentary contact operation
• ROHS3 compliance certification
• Moisture Sensitivity Level 1 rating

The ALD26602DNUA meets all these criteria and is classified as an active product, providing a direct functional replacement for the obsolete ALD29902DN-A-6V.

Parameter Comparison

Engineering Selection Recommendations

The ALD26602DNUA is the direct substitute for the ALD29902DN-A-6V. Both components share identical electrical specifications, mechanical form factor, and regulatory compliance certifications. The primary distinction is product status: the ALD29902DN-A-6V is obsolete, while the ALD26602DNUA is actively manufactured and supported. Selection of the ALD26602DNUA ensures continued availability and supply chain reliability for applications requiring 30mm illuminated 6V pushbutton switches with ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can the ALD26602DNUA directly replace the ALD29902DN-A-6V in existing designs?

A: Yes. Both components are 30mm illuminated pushbutton switches rated for 6V operation with identical contact configurations, RoHS compliance status, and moisture sensitivity ratings. Direct substitution is supported at the mechanical and electrical interface level.

Q: What is the significance of the 2NC contact designation on the ALD26602DNUA?

A: The 2NC designation indicates two normally closed contacts. This contact configuration is compatible with the momentary pushbutton operation of the original ALD29902DN-A-6V.

Q: Are there packaging differences between these parts?

A: The ALD29902DN-A-6V packaging is listed as standard, while the ALD26602DNUA is supplied in bulk packaging. Both are suitable for component-level integration; packaging selection depends on procurement and assembly requirements.

Q: Why is the ALD29902DN-A-6V classified as obsolete?

A: Obsolescence typically results from manufacturer discontinuation. The ALD26602DNUA represents the current active equivalent from IDEC for this product category.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the ALD29902DN-A-6V and ALD26602DNUA are ROHS3 compliant and carry EAR99 export classification, meeting current regulatory requirements for electronic component use.
