Key Parameters

Substitute Part Grouping Explanation

The ABFD111NUB qualifies as a direct substitute based on the following alignment of critical parameters:

• Identical manufacturer (IDEC)
• Identical base product series (ABFD111)
• Matching contact configuration (1NO 1NC)
• Matching action type (momentary)
• Matching button size (30MM)
• Identical RoHS3 compliance status
• Identical MSL rating (1 - Unlimited)
• Identical ECCN and HTSUS classifications

The primary distinction is product status: ABFD111NUB maintains active production status, ensuring continued availability and supply chain reliability.

Parameter Comparison

Engineering Selection Recommendations

The ABFD111NUB is the appropriate substitute for ABFD111N-B applications based on:

• Electrical equivalence: identical contact configuration and action characteristics
• Mechanical compatibility: matching 30MM form factor and mounting interface
• Regulatory alignment: both components maintain ROHS3 compliance and identical trade classifications
• Supply continuity: active product status ensures reliable procurement for replacement and new installations

Selection of ABFD111NUB eliminates obsolescence risk while maintaining full functional and physical compatibility with existing circuit designs and mechanical assemblies.

Frequently Asked Questions (FAQ)

Q: Can ABFD111NUB be used as a direct replacement for ABFD111N-B in existing assemblies?

A: Yes. Both components share identical electrical specifications (1NO 1NC contact configuration), mechanical dimensions (30MM), and action type (momentary). No circuit redesign or mechanical modification is required.

Q: What is the primary reason for substitution?

A: ABFD111N-B is classified as obsolete. ABFD111NUB maintains active production status, ensuring continued availability and supply chain stability.

Q: Are there compliance differences between the two parts?

A: No. Both components are ROHS3 compliant, carry identical MSL ratings (1 - Unlimited), and share the same ECCN and HTSUS classifications.

Q: Does packaging differ between these parts?

A: Yes. ABFD111N-B uses standard packaging, while ABFD111NUB is supplied in bulk packaging. This distinction affects order quantities and handling but does not impact electrical or mechanical performance.

Q: Are there any electrical parameter differences?

A: No. The contact configuration (1NO 1NC), action type (momentary), and all electrical characteristics are identical between both parts.
