ABFD120N-S Equivalent & Substitute Parts

Part Overview

The ABFD120N-S is a 30mm pushbutton switch manufactured by IDEC, classified as a momentary action pushbutton with two normally open (2NO) contacts. This component is currently listed as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing maintenance and repair applications. The substitute part ABFD120NUS maintains identical electrical and mechanical specifications while offering active product status and continued availability.

Substitute Part Grouping Explanation

The ABFD120NUS qualifies as a direct substitute for the ABFD120N-S based on the following criteria:

• Identical manufacturer (IDEC)
• Identical base product number (ABFD120)
• Identical button size (30mm)
• Identical contact configuration (2NO momentary action)
• Identical RoHS compliance status (ROHS3 Compliant)
• Identical moisture sensitivity level (MSL 1 - Unlimited)
• Identical electrical classification (ECCN EAR99, HTSUS 8536.50.9035)

The primary distinction is product status: ABFD120NUS is active and in current production, whereas ABFD120N-S is obsolete. Packaging differs (Bulk for ABFD120NUS versus dash notation for ABFD120N-S), but this does not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using ABFD120N-S, the ABFD120NUS is the appropriate substitute. The obsolete status of ABFD120N-S makes ABFD120NUS the only viable long-term sourcing option. Both parts maintain identical RoHS3 compliance and regulatory classifications (ECCN EAR99, HTSUS 8536.50.9035), ensuring no change in supply chain or regulatory documentation requirements. The active product status of ABFD120NUS provides assured availability and continued manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can ABFD120NUS be used as a direct replacement for ABFD120N-S? A: Yes. Both parts share identical electrical specifications (2NO momentary action), mechanical dimensions (30mm button), and compliance certifications (ROHS3). The only functional difference is product status; ABFD120NUS is in active production.

Q: What is the significance of the packaging difference between these parts? A: ABFD120N-S uses dash notation packaging, while ABFD120NUS is supplied in bulk packaging. This affects order quantities and handling but does not alter the electrical or mechanical performance of the component.

Q: Are there any regulatory or compliance concerns when substituting ABFD120NUS for ABFD120N-S? A: No. Both parts carry identical RoHS3 compliance, ECCN EAR99 classification, and HTSUS code 8536.50.9035. No regulatory documentation changes are required.

Q: Why is ABFD120N-S listed as obsolete? A: Product obsolescence is determined by the manufacturer. ABFD120NUS represents the active continuation of this product line and should be used for all new designs and replacements.

Q: Are the contact configurations identical between these parts? A: Yes. Both parts feature 2NO (two normally open) momentary action contacts with identical electrical behavior.
