Substitute Part Grouping Explanation

Substitution of the ASLD29902DN-104-A-12V is based on the following critical parameters that must align between the main part and substitute components:

• Manufacturer: IDEC (same manufacturer ensures design compatibility)
• Base Product Series: ASLD (common platform architecture)
• Voltage Rating: 12V operation
• Function: Selector switch for position selection
• RoHS Compliance: ROHS3 Compliant (regulatory requirement match)
• Moisture Sensitivity Level: MSL 1 (Unlimited) (environmental tolerance match)
• ECCN/HTSUS Classification: Identical trade classification codes

The substitute part ASLD21102DNU-104-A meets all these criteria while maintaining active product status, providing a direct functional replacement for the obsolete ASLD29902DN-104-A-12V.

Parameter Comparison

Engineering Selection Recommendations

The ASLD21102DNU-104-A is the direct substitute for ASLD29902DN-104-A-12V based on the following engineering criteria:

• Regulatory Compliance: Both components maintain ROHS3 compliance, ensuring compatibility with current environmental regulations
• Product Status: The substitute maintains active product status, guaranteeing ongoing availability and supply chain continuity
• Electrical Specifications: Identical voltage rating (12V) and functional classification ensure direct electrical compatibility
• Environmental Rating: Matching MSL 1 (Unlimited) rating confirms equivalent moisture and thermal tolerance
• Trade Classification: Identical ECCN and HTSUS codes confirm equivalent regulatory classification for import/export purposes

The transition from the obsolete ASLD29902DN-104-A-12V to the active ASLD21102DNU-104-A requires only packaging consideration, as the substitute is supplied in bulk format rather than standard packaging.

Frequently Asked Questions (FAQ)

Q: Can ASLD21102DNU-104-A directly replace ASLD29902DN-104-A-12V in existing applications?

A: Yes. Both components share identical voltage ratings (12V), RoHS compliance status (ROHS3), MSL ratings (1 - Unlimited), and functional classification as selector switches. The primary difference is packaging format (bulk versus standard).

Q: What is the significance of the "2POS" designation in the substitute part number?

A: The "2POS" indicates a 2-position selector switch configuration. This specification is provided in the substitute part's detailed description and represents the functional capability of the component.

Q: Are there any compliance or certification differences between these parts?

A: No. Both components carry identical ROHS3 compliance, MSL 1 rating, ECCN (EAR99), and HTSUS (8536.50.9025) classifications, confirming equivalent regulatory and environmental status.

Q: Why is the main part listed as obsolete?

A: Product obsolescence is a manufacturer lifecycle determination. The availability of the active substitute ASLD21102DNU-104-A ensures that applications requiring this selector switch functionality can continue with current, supported components.

Q: Does packaging format affect electrical or mechanical compatibility?

A: No. Packaging format (bulk versus standard) affects only procurement and handling procedures, not electrical performance or mechanical fit. Component specifications remain identical regardless of packaging configuration.
