M2013SA2G30 Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The M2013SA2G30 is a toggle switch manufactured by NKK Switches, classified as SPDT (Single Pole Double Throw) with On-Off-On switching function. This component is rated for 0.4VA at 28V AC/DC with through-hole, right-angle mounting. The product is currently obsolete, making identification of functionally equivalent alternatives essential for design continuity and component sourcing in legacy system maintenance and new designs requiring compatible switching solutions.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the M2013SA2G30 are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Circuit configuration: SPDT
• Mounting type: Through hole, right angle
• Termination style: PC Pin
• Actuator type: Standard round
• Illumination: Non-illuminated
• Material composition: Brass, chrome-plated actuator
• Epoxy sealed terminals

Electrical Performance Boundaries:

• Current rating: Minimum 0.4VA (AC/DC)
• Voltage rating: Minimum 28V (AC/DC)
• Operating temperature: Must encompass -30°C to 85°C range

Regulatory Compliance:

• RoHS3 compliance required for new designs
• ECCN classification: EAR99

Two substitute parts meet these criteria with documented variations in specific parameters.

Parameter Comparison

Engineering Selection Recommendations

7103SD9ABE (C&K) - Direct Manufacturer Substitute:

This part maintains SPDT circuit configuration, On-Off-On switching function, and identical current rating (0.4VA AC/DC). It is classified as a direct substitute with the following considerations: voltage rating is reduced to 20V AC/DC, which is below the original 28V specification. This part is active in production with ROHS3 compliance and REACH affected status. Selection is appropriate only for applications where 20V operation is acceptable and does not exceed the original design voltage requirements.

A121S1D9AB (Electroswitch) - Similar Manufacturer Substitute:

This part provides SPDT circuit configuration with higher current capacity (0.5VA AC/DC) and maintains 28V AC/DC voltage rating matching the original specification. Operating temperature range extends to 90°C, exceeding the original -30°C to 85°C range. Electrical life is rated at 60,000 cycles, surpassing the original 50,000 cycles. The switch function differs as On-On rather than On-Off-On. This part is active in production with RoHS compliance. Selection is appropriate for applications where the On-On function is compatible with circuit design and higher electrical life is beneficial.

Both substitute parts are currently in active production status, providing supply continuity for the obsolete M2013SA2G30.

Frequently Asked Questions (FAQ)

Q: Can the 7103SD9ABE replace the M2013SA2G30 in all applications?

A: The 7103SD9ABE is electrically compatible for SPDT On-Off-On switching at 0.4VA. However, its voltage rating of 20V AC/DC is lower than the original 28V specification. Substitution is valid only if the application operates at or below 20V. Circuit voltage requirements must be verified before selection.

Q: What is the functional difference between the A121S1D9AB and the original part?

A: The A121S1D9AB provides On-On switching function, whereas the M2013SA2G30 provides On-Off-On function. These are distinct switching behaviors. The On-On configuration means both switch positions are active, with no neutral center position. Application circuit design must accommodate this functional difference.

Q: Are both substitute parts RoHS compliant?

A: Yes. The 7103SD9ABE carries ROHS3 compliance. The A121S1D9AB carries RoHS compliance. Both meet regulatory requirements for new designs. The 7103SD9ABE has REACH affected status, while the A121S1D9AB has vendor undefined REACH status.

Q: What are the packaging differences?

A: The M2013SA2G30 is supplied in bulk packaging. The 7103SD9ABE is supplied in tray packaging. The A121S1D9AB is supplied in bulk packaging. Packaging format may affect procurement quantities and handling procedures.

Q: How do actuator length differences affect mechanical compatibility?

A: The M2013SA2G30 has an actuator length of 12.28mm. The 7103SD9ABE measures 12.45mm, and the A121S1D9AB measures 10.41mm. Panel cutout dimensions and mechanical clearances must be verified to ensure physical fit within the enclosure or PCB assembly.

Q: Which substitute part has the longest electrical life?

A: The A121S1D9AB is rated for 60,000 electrical cycles, compared to 50,000 cycles for the M2013SA2G30 and 40,000 cycles for the 7103SD9ABE. Higher cycle ratings indicate extended operational life under repeated switching conditions.
