Key Parameters

Substitute Part Grouping Explanation

Substitution of the MS12AFG01 is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: SPDT topology must be maintained
• Contact Timing: Non-shorting (BBM) contact behavior required
• Electrical Ratings: 0.4VA at 28V AC/DC minimum
• Mounting Interface: Panel mount configuration with solder lug termination
• Physical Dimensions: Actuator length (5.10mm) and switch travel (2.20mm) compatibility
• Contact Material & Finish: Copper with gold plating for reliability and corrosion resistance
• Environmental Compliance: ROHS3 compliance and REACH unaffected status

The substitute part MSN12AFG01 from NKK Switches meets all specified electrical, mechanical, and environmental parameters, establishing direct functional equivalence with the obsolete MS12AFG01.

Parameter Comparison

Engineering Selection Recommendations

The MSN12AFG01 is the designated manufacturer substitute for the obsolete MS12AFG01. Both components are manufactured by NKK Switches and share identical ECCN and HTSUS classifications, confirming regulatory and trade alignment. The substitute part maintains ROHS3 compliance, ensuring compatibility with modern procurement and environmental standards.

The transition from the obsolete MS12AFG01 to the active MSN12AFG01 provides access to current manufacturing stock and ongoing supply chain support. Selection of the MSN12AFG01 is appropriate for applications requiring direct replacement of the MS12AFG01 in legacy systems or new designs requiring equivalent SPDT slide switch functionality.

Frequently Asked Questions (FAQ)

Q: Can the MSN12AFG01 directly replace the MS12AFG01 in existing applications?

A: Yes. Both components are manufactured by NKK Switches and share the same series designation and functional classification. The MSN12AFG01 is the active production equivalent of the obsolete MS12AFG01.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution is based on SPDT circuit configuration, 0.4VA current rating at 28V AC/DC, non-shorting contact timing, panel mount configuration, and solder lug termination. These parameters must remain constant across substitute parts.

Q: Are there packaging differences between the MS12AFG01 and MSN12AFG01?

A: Both components are supplied in bulk packaging. No alternative packaging formats are specified in the available data.

Q: What is the significance of the product status change from Obsolete to Active?

A: The transition from obsolete to active status indicates that the MSN12AFG01 is currently manufactured and available through standard distribution channels, ensuring reliable supply for replacement and new applications.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the MS12AFG01 and MSN12AFG01 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component procurement.
