Frequently Asked Questions (FAQ)

Q: Can ASLD21QM420DNUA directly replace ASLD219920DN-A-240V? A: Yes. Both parts share identical voltage ratings (240V), manufacturer (IDEC), compliance certifications (ROHS3), and environmental specifications (MSL 1). The substitute is an active product, ensuring continued availability.

Q: What is the difference between the two part numbers? A: The ASLD21QM420DNUA is the active equivalent designation. The primary difference is product status: ASLD219920DN-A-240V is obsolete, while ASLD21QM420DNUA is active. Both maintain identical electrical and mechanical specifications for selector switch applications.

Q: Does packaging affect substitution? A: Packaging format (standard vs. bulk) does not affect electrical or mechanical compatibility. Selection between packaging options depends on procurement quantity and inventory management requirements.

Q: Are compliance certifications identical? A: Yes. Both parts are ROHS3 compliant, carry EAR99 export classification, and share the same HTSUS tariff code (8536.50.9025). Environmental handling (MSL 1) is identical for both parts.

Q: Why is the original part obsolete? A: Product obsolescence is determined by the manufacturer. The ASLD21QM420DNUA represents the current active equivalent for continued system support and new procurement.
