M2018SS4G01 Equivalent & Substitute Parts

Part Overview

The M2018SS4G01 is a toggle switch manufactured by NKK Switches, configured as a Single Pole Double Throw (SPDT) panel mount switch with momentary-off-momentary (Mom-Off-Mom) functionality. Rated for 0.4VA at 28V AC/DC, this switch features a standard round actuator with a 10.50mm length and solder lug termination. The product is classified as obsolete, making identification of equivalent substitute parts essential for ongoing maintenance, repair, and system continuity in applications where this switch was originally specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the M2018SS4G01 is determined by strict equivalence across 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)
• Actuator specifications (Standard Round, 10.50mm length)
• Termination style (Solder Lug)
• Panel cutout dimensions (Circular - 6.50mm Dia)
• Bushing thread specification (M6 x 0.75)
• Operating temperature range (-30°C ~ 85°C)
• Electrical life rating (50,000 Cycles)

The substitute part MN18SS4G01 maintains functional and mechanical compatibility with the original M2018SS4G01 across all specified parameters, enabling direct replacement in existing applications.

Parameter Comparison

Engineering Selection Recommendations

The MN18SS4G01 is the designated substitute for the obsolete M2018SS4G01. Both parts are manufactured by NKK Switches and share identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: the M2018SS4G01 is obsolete, while the MN18SS4G01 maintains active production status, ensuring availability for new procurement and replacement applications.

Both parts comply with ROHS3 standards and carry the same HTSUS and ECCN classifications, confirming regulatory equivalence. Selection of the MN18SS4G01 is appropriate for direct replacement in any application originally specified with the M2018SS4G01.

Frequently Asked Questions (FAQ)

Q: Can the MN18SS4G01 directly replace the M2018SS4G01 in existing designs?

A: Yes. Both parts share identical circuit configuration (SPDT), switch function (Mom-Off-Mom), electrical ratings (0.4VA at 28V AC/DC), mechanical dimensions, and termination style. Direct substitution is supported without design modification.

Q: What is the difference between these two part numbers?

A: The M2018SS4G01 is classified as obsolete, while the MN18SS4G01 is in active production. All electrical and mechanical specifications are equivalent.

Q: Are there packaging differences between these parts?

A: The M2018SS4G01 is specified with standard packaging, while the MN18SS4G01 is supplied in bulk packaging. This distinction does not affect functional or mechanical compatibility.

Q: Do both parts meet the same compliance standards?

A: Both parts carry identical HTSUS (8536.50.9065) and ECCN (EAR99) classifications. The M2018SS4G01 is explicitly ROHS3 compliant; compliance status for the MN18SS4G01 is not specified in available documentation.

Q: What is the operating temperature range for these switches?

A: The specified operating temperature range is -30°C to 85°C for the M2018SS4G01. Equivalent operating range specifications for the MN18SS4G01 are not provided in the available data.
