Frequently Asked Questions (FAQ)

Q: Can the ASD32K20NU directly replace the ASD32K20N in existing installations?

A: Yes. Both components share the ASD32 base product number and maintain identical electrical specifications (DPST-NO circuit, 3-position configuration, 10A AC / 8A DC ratings, 110V AC / 24V DC voltage ratings), mechanical mounting (panel mount, screw terminal, 30.50mm circular cutout), and compliance certifications (ROHS3, MSL Level 1).

Q: What is the difference between the ASD32K20N and ASD32K20NU?

A: The primary difference is product status. The ASD32K20N is obsolete, while the ASD32K20NU is active. Both maintain identical electrical and mechanical specifications and regulatory compliance.

Q: Are there packaging differences between these parts?

A: Both components are supplied in bulk packaging. No packaging format changes affect substitution compatibility.

Q: Why is the ASD32K20N obsolete?

A: Product obsolescence is determined by the manufacturer. The ASD32K20NU represents the current active equivalent within the IDEC ASD32 keylock switch family.

Q: What certifications apply to the substitute part?

A: The ASD32K20NU maintains ROHS3 compliance and MSL Level 1 (Unlimited) rating, matching the original component's regulatory requirements.
