Frequently Asked Questions (FAQ)

Q: Can the AYD301NUB directly replace the AYD301N-B in existing installations?

A: Yes. Both parts share identical mechanical form factor (30mm), manufacturer origin (IDEC), regulatory compliance status, and environmental ratings. The AYD301NUB is designed as the active production equivalent of the obsolete AYD301N-B.

Q: What is the significance of the packaging difference between these parts?

A: The AYD301N-B is supplied in standard packaging, while the AYD301NUB is available in bulk packaging. Packaging format does not affect electrical or mechanical compatibility; it reflects current distribution and inventory management practices for the active product line.

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

A: No. Both parts maintain identical ROHS3 compliance, ECCN classification (EAR99), and HTSUS coding. They are equivalent from regulatory and export control perspectives.

Q: Why is the AYD301N-B listed as obsolete?

A: Product obsolescence reflects IDEC's transition to the AYD301NUB as the current production model. The AYD301NUB incorporates the same functional design while meeting current manufacturing and supply chain standards.

Q: What does the "1NC" designation in the AYD301NUB description indicate?

A: The "1NC" notation refers to the contact configuration: one normally closed contact. This is the standard contact arrangement for emergency stop pushbutton switches in this product family.
