Key Parameters

Substitute Part Grouping Explanation

Substitution for the ALD39902DN-A-6V is determined by the following critical parameters:

• Manufacturer: IDEC (same manufacturer ensures design compatibility)
• Component Type: Pushbutton Switch (functional equivalence)
• Voltage Rating: 6V (electrical compatibility)
• RoHS Compliance: ROHS3 Compliant (regulatory alignment)
• Moisture Sensitivity Level: 1 (Unlimited) (environmental tolerance match)
• ECCN and HTSUS Classification: Identical codes (trade and export compliance)

The identified substitute part ALD36602DNUA meets all critical substitution criteria while maintaining functional and regulatory equivalence.

Parameter Comparison

Engineering Selection Recommendations

The ALD36602DNUA is an active substitute for the obsolete ALD39902DN-A-6V. Both parts are manufactured by IDEC and share identical voltage ratings (6V), RoHS compliance (ROHS3), and environmental classifications (MSL 1). Both components maintain the same ECCN and HTSUS codes, ensuring regulatory and trade compliance equivalence.

The primary difference is the button size: the substitute features a 40mm button compared to the original 30mm. This dimensional change must be evaluated against mechanical mounting and panel layout requirements in the target application. Both parts are currently available in inventory, with the substitute in active production status.

Frequently Asked Questions (FAQ)

Q: Can the ALD36602DNUA directly replace the ALD39902DN-A-6V?

A: Both parts share identical electrical specifications (6V rating), RoHS compliance, and environmental classifications. The primary consideration is the button size difference (40mm vs. 30mm), which affects mechanical fit and panel integration.

Q: What is the significance of the product status difference?

A: The ALD39902DN-A-6V is obsolete, while the ALD36602DNUA is active. Active status indicates ongoing manufacturer support, availability, and compliance with current standards.

Q: Are both parts RoHS compliant?

A: Yes, both the ALD39902DN-A-6V and ALD36602DNUA are ROHS3 compliant, meeting current environmental and hazardous substance restrictions.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling.

Q: Are the ECCN and HTSUS codes identical?

A: Yes, both parts share identical ECCN (EAR99) and HTSUS (8536.50.9035) codes, ensuring equivalent export control and tariff classification.
