M2012S3S2G30 Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The M2012S3S2G30 is a toggle switch manufactured by NKK Switches, configured as a Single Pole Double Throw (SPDT) with On-On switching function. This through-hole, right-angle mounted component is rated for 0.4VA at 28V AC/DC operation. The product is currently obsolete, making identification of equivalent and substitute parts essential for ongoing system maintenance and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the M2012S3S2G30 are identified based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Circuit configuration (SPDT)
• Switch function (On-On)
• Current rating (0.4VA AC/DC)
• Mounting type (Through Hole, Right Angle)
• Termination style (PC Pin)
• Operating temperature range (-30°C to 85°C)
• Actuator type (Standard Round)
• RoHS3 compliance

Voltage Rating Consideration: Substitute parts must operate at or above the 28V AC/DC rating of the main part. Parts rated below 28V are not suitable for direct substitution in applications requiring the full voltage specification.

Electrical Life: The M2012S3S2G30 specifies 50,000 electrical cycles. Substitute parts with lower cycle ratings may be considered where application duty cycles permit.

Parameter Comparison

Engineering Selection Recommendations

MN12S3S2G30 (NKK Switches - Manufacturer Recommended): This part is the primary substitute option. It is manufactured by the same original equipment manufacturer (NKK Switches) and maintains identical electrical specifications including 28V AC/DC voltage rating, 0.4VA current rating, and -30°C to 85°C operating temperature range. The part is currently in active production status with 796 units in stock. ROHS3 compliance is maintained. This substitute provides the highest compatibility assurance for direct replacement applications.

100SP1T2B4M6RE (E-Switch - Similar Alternative): This part shares the same circuit configuration (SPDT), switch function (On-On), current rating (0.4VA), mounting type (Through Hole, Right Angle), and operating temperature range (-30°C to 85°C). However, the voltage rating is specified at 20V AC/DC, which is below the 28V requirement of the main part. This part is suitable only for applications where the actual operating voltage does not exceed 20V. The actuator length differs at 5.08mm compared to 6.50mm on the main part, and electrical life is rated at 40,000 cycles versus 50,000 cycles. The part is in active production with 3426 units available in stock and maintains ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can MN12S3S2G30 be used as a direct replacement for M2012S3S2G30? A: Yes. MN12S3S2G30 is the manufacturer-recommended substitute with identical electrical specifications, voltage ratings, current ratings, and operating temperature range. Both parts are SPDT On-On toggle switches with PC pin termination and through-hole right-angle mounting.

Q: What is the key limitation of 100SP1T2B4M6RE as a substitute? A: The voltage rating of 100SP1T2B4M6RE is 20V AC/DC, which is lower than the 28V specification of M2012S3S2G30. This part is only suitable for applications where the actual circuit voltage does not exceed 20V.

Q: Does the difference in actuator length between M2012S3S2G30 (6.50mm) and 100SP1T2B4M6RE (5.08mm) affect mechanical compatibility? A: Actuator length differences may affect panel cutout alignment and user interface ergonomics. Mechanical fit verification is required when substituting parts with different actuator lengths in existing mechanical assemblies.

Q: Are both substitute parts RoHS3 compliant? A: Yes. Both MN12S3S2G30 and 100SP1T2B4M6RE are ROHS3 compliant, matching the compliance status of the main part M2012S3S2G30.

Q: What is the difference in electrical life between these parts? A: M2012S3S2G30 is rated for 50,000 electrical cycles. MN12S3S2G30 does not specify electrical life in the provided data. 100SP1T2B4M6RE is rated for 40,000 cycles. For applications requiring extended cycle life, the main part or MN12S3S2G30 are preferred.

Q: Which substitute has the best inventory availability? A: 100SP1T2B4M6RE has the highest inventory with 3426 units in stock, followed by MN12S3S2G30 with 796 units. However, voltage rating compatibility must be verified before selection based on inventory alone.

Q: Are all three parts through-hole, right-angle mounted? A: Yes. M2012S3S2G30, MN12S3S2G30, and 100SP1T2B4M6RE all feature through-hole, right-angle mounting with PC pin termination.
