Substitute Part Grouping Explanation

Substitution of the M2018WBG01 is determined by strict alignment of the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (Mom-Off-Mom)
• Current and voltage ratings (0.4VA at 28V AC/DC)
• Mounting type (Panel Mount)
• Mechanical interface (M12 x 1 bushing thread, 12.50mm circular cutout)
• Actuator specifications (Standard Round, 20.00mm length)
• Termination style (Solder Lug)
• Environmental protection (IP67 ingress protection)
• Operating temperature range (-30°C ~ 85°C)

The substitute part MN18WBG01 is listed as the manufacturer-recommended equivalent and maintains compatibility within the M-series toggle switch family from NKK Switches.

Parameter Comparison

Engineering Selection Recommendations

The M2018WBG01 is designated as obsolete by the manufacturer. The MN18WBG01 is the manufacturer-recommended substitute and carries Active product status, ensuring continued availability and supply chain support. Both parts maintain ROHS3 compliance and identical export classification (EAR99), supporting regulatory consistency in applications requiring component replacement.

Selection of MN18WBG01 as a substitute is supported by manufacturer designation and shared compliance certifications. The substitute part is available in bulk packaging, contrasting with the original tray packaging of the M2018WBG01.

Frequently Asked Questions (FAQ)

Q: Why is the M2018WBG01 no longer available? A: The M2018WBG01 has reached end-of-life status and is classified as obsolete by NKK Switches. The MN18WBG01 represents the active product line continuation.

Q: Is MN18WBG01 a direct replacement for M2018WBG01? A: MN18WBG01 is designated by the manufacturer as the recommended equivalent. Both are SPDT toggle switches from NKK Switches with identical export and compliance classifications.

Q: What are the key parameters that must match for substitution? A: Critical matching parameters include circuit configuration (SPDT), switch function (Mom-Off-Mom), electrical ratings (0.4VA at 28V AC/DC), mounting interface (M12 x 1 panel mount), actuator specifications (Standard Round, 20.00mm), and environmental protection (IP67).

Q: Are there packaging differences between the main part and substitute? A: Yes. The M2018WBG01 is supplied in tray packaging, while MN18WBG01 is supplied in bulk packaging. This affects inventory management and handling procedures but does not impact functional compatibility.

Q: Do both parts meet the same compliance standards? A: Both M2018WBG01 and MN18WBG01 are ROHS3 compliant and classified under identical ECCN (EAR99) and HTSUS codes (8536.50.9065).
