Substitute Part Grouping Explanation

Substitution eligibility for the ASLD29920DN-A-12V is determined by the following critical parameters:

• Manufacturer: IDEC (same manufacturer ensures design compatibility)
• Functional Category: Selector Switch Position (same switching function)
• Voltage Rating: 12V (electrical compatibility requirement)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement match)
• Moisture Sensitivity Level: 1 (Unlimited) (environmental tolerance match)
• HTSUS Classification: 8536.50.9025 (tariff and product classification alignment)

The substitute part ASLD21120DNUA meets all these criteria, confirming functional and regulatory equivalence with the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can ASLD21120DNUA directly replace ASLD29920DN-A-12V in existing applications?

A: Yes. Both parts share identical voltage ratings (12V), RoHS compliance status (ROHS3), moisture sensitivity levels (MSL 1), and regulatory classifications (ECCN/HTSUS). These parameters define functional compatibility for selector switch applications.

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

A: The "2POS" notation in ASLD21120DNUA indicates a 2-position selector configuration. This specification is provided in the substitute part description and represents the functional characteristic of the active replacement component.

Q: Does packaging format affect substitution eligibility?

A: Packaging format (Bulk for the substitute) does not affect electrical or functional compatibility. Packaging considerations are logistical and procurement-related, not technical substitution criteria.

Q: Are there inventory implications when switching from the original to the substitute part?

A: The original part (ASLD29920DN-A-12V) shows 1161 units in stock, while the substitute (ASLD21120DNUA) shows 923 units available. Both represent current inventory levels and do not affect technical substitution validity.

Q: Why is the original part classified as obsolete?

A: Obsolescence is a manufacturer lifecycle status indicating discontinued production. The active substitute part ensures continued availability for applications requiring this selector switch functionality.
