• Trade Classification: Both share identical ECCN (EAR99) and HTSUS codes (8536.50.9035)
• Base Product Series: ABD420NUB is derived from the ABD420 base product number, indicating design family relationship
• Product Status: ABD420NUB is listed as active, providing current availability for replacement applications

Parameter Comparison

Engineering Selection Recommendations

The ABD420NUB is the designated substitute for the obsolete ABD420N-B. Selection of this alternative is supported by:

• Regulatory Compliance: Both parts maintain identical ROHS3 compliance status, ensuring compatibility with current environmental regulations
• Supply Chain Continuity: ABD420NUB is currently in active production status with confirmed inventory availability (1061 pcs), whereas ABD420N-B is obsolete
• Manufacturer Consistency: Continued use of IDEC as the original equipment manufacturer preserves design integrity and quality assurance protocols
• Trade Compliance: Identical ECCN and HTSUS classifications ensure no change to export control or tariff treatment
• Physical Integration: Matching 30.50mm circular panel cutout dimensions enable direct mechanical substitution without enclosure modification

Frequently Asked Questions (FAQ)

Q: Can ABD420NUB be used as a direct replacement for ABD420N-B in existing equipment?

A: Yes. Both parts share identical physical form factors (30mm panel mount with 30.50mm circular cutout), manufacturer origin (IDEC), and regulatory compliance status (ROHS3). The ABD420NUB is the active production equivalent.

Q: What is the difference in electrical specifications between these parts?

A: The ABD420NUB provides documented electrical specifications: DPST-NO circuit configuration, 10A AC / 8A DC current rating, 110V AC / 24V DC voltage rating, and off-momentary switch function. The ABD420N-B specifications are not provided in available documentation.

Q: Are there any packaging differences between ABD420N-B and ABD420NUB?

A: ABD420N-B packaging is listed as standard (-), while ABD420NUB is supplied in bulk packaging. This represents a supply format difference only and does not affect component functionality or mechanical compatibility.

Q: What is the mechanical life expectancy of the substitute part?

A: The ABD420NUB is rated for 5,000,000 mechanical cycles under specified operating conditions (-25°C to 70°C).

Q: Are both parts suitable for the same environmental conditions?

A: Both parts maintain MSL 1 (Unlimited) moisture sensitivity rating. The ABD420NUB additionally specifies IP65 ingress protection (dust tight, water resistant), providing documented environmental sealing performance.
