M2018SS2G30 Equivalent & Substitute Parts

Part Overview

The M2018SS2G30 is a toggle switch manufactured by NKK Switches, configured as a Single Pole Double Throw (SPDT) momentary-off-momentary switch with a rated capacity of 0.4VA at 28V AC/DC. This through-hole, right-angle mounted component features a standard round actuator with a 10.50mm length and circular panel cutout of 6.50mm diameter. The product is currently obsolete, making identification of equivalent substitute parts essential for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M2018SS2G30 is determined by strict alignment with the following electrical and mechanical parameters:

• Circuit configuration must be SPDT
• Switch function must be Mom-Off-Mom
• Current rating must be 0.4VA (AC/DC)
• Voltage rating must be 28V AC and 28V DC
• Mounting type must be through-hole, right-angle configuration
• Actuator type must be standard round with 10.50mm length
• Panel cutout must accommodate circular 6.50mm diameter
• Termination style must be PC Pin
• Operating temperature range must span -30°C to 85°C minimum
• RoHS3 compliance is required

The substitute part MN18SS2G30 meets these criteria and is classified as an equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The MN18SS2G30 is identified as the manufacturer-recommended substitute for the obsolete M2018SS2G30. Both parts are manufactured by NKK Switches and maintain ROHS3 compliance. The primary distinction is product status: M2018SS2G30 is obsolete while MN18SS2G30 is active, ensuring continued availability and supply chain reliability. Packaging differs between tray and bulk configurations, which may affect procurement and inventory management strategies but does not impact functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can MN18SS2G30 be used as a direct replacement for M2018SS2G30?

A: MN18SS2G30 is the manufacturer-recommended substitute. Both parts are SPDT toggle switches from NKK Switches with ROHS3 compliance. Functional compatibility is established through the manufacturer's substitution designation.

Q: What is the difference between tray and bulk packaging?

A: Tray packaging organizes components in structured trays for automated handling and protection during transport. Bulk packaging consolidates parts without individual compartmentalization. This distinction affects logistics and storage but does not alter electrical or mechanical performance.

Q: Why is the M2018SS2G30 listed as obsolete?

A: Obsolete status indicates the part is no longer in active production. The manufacturer has transitioned to the MN18SS2G30 as the current equivalent, ensuring design continuity while supporting legacy system maintenance through the active substitute part.

Q: Are there any compliance differences between the two parts?

A: Both M2018SS2G30 and MN18SS2G30 are ROHS3 compliant and carry the same ECCN (EAR99) and HTSUS (8536.50.9065) classifications, confirming regulatory equivalence.
