Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M2018SD3G01 is determined by the following critical parameters:

• Circuit Configuration: SPDT topology must be maintained
• Switch Function: Momentary-off-momentary operation required
• Electrical Ratings: 0.4VA capacity at 28V AC/DC minimum
• Mounting Interface: Panel mount with 6.50mm circular cutout and 1/4-40 bushing thread
• Actuator Specifications: Standard round actuator with 10.50mm length
• Termination: Solder lug connection style
• Environmental Protection: IP67 rating for dust and water ingress protection
• Compliance: ROHS3 compliance required

The substitute part MN18SD3G01 from NKK Switches meets these criteria as a direct equivalent within the manufacturer's product line.

Parameter Comparison

Engineering Selection Recommendations

The MN18SD3G01 is classified as an active product with current manufacturing status, whereas the M2018SD3G01 is obsolete. Both components maintain ROHS3 compliance and identical export classification (EAR99), ensuring regulatory consistency in system applications. The substitute part is recommended for new designs and replacement applications where the original M2018SD3G01 is no longer available through standard distribution channels. Both components share identical HTSUS commodity codes, confirming functional and structural equivalence within the toggle switch category.

Frequently Asked Questions (FAQ)

Q: Can MN18SD3G01 directly replace M2018SD3G01 in existing assemblies?

A: Yes. Both components are manufactured by NKK Switches and share identical circuit configuration (SPDT), mounting interface (panel mount with 6.50mm circular cutout and 1/4-40 bushing thread), and termination style (solder lug). The substitute part is active in production, whereas the original is obsolete.

Q: What are the critical parameters for substitution compatibility?

A: Circuit configuration (SPDT), switch function (momentary-off-momentary), electrical ratings (0.4VA at 28V AC/DC), panel mount interface dimensions, actuator specifications (standard round, 10.50mm length), solder lug termination, and IP67 ingress protection rating must all be maintained.

Q: Are there compliance differences between the two parts?

A: No. Both M2018SD3G01 and MN18SD3G01 are ROHS3 compliant with identical ECCN (EAR99) and HTSUS (8536.50.9065) classifications.

Q: Why is the original M2018SD3G01 marked as obsolete?

A: Product obsolescence indicates the component is no longer manufactured or supported by NKK Switches. The MN18SD3G01 serves as the active equivalent for continued system support and new applications.

Q: What packaging options are available for the substitute part?

A: The MN18SD3G01 is available in bulk packaging, consistent with the original M2018SD3G01 distribution format.
