Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M2012SS1G03 is determined by the following critical parameters:

• Circuit Configuration: Must be SPDT
• Switch Function: Must be On-On
• Current Rating: Must support 0.4VA (AC/DC)
• Voltage Rating: Must support minimum 28V AC and 28V DC
• Mounting Type: Must be Panel Mount
• Termination Style: Must be PC Pin
• Panel Cutout Diameter: Must accommodate 6.50mm circular cutout
• Bushing Thread: Must be 1/4-40
• Actuator Type: Must be Standard Round

The substitute parts listed below meet these core electrical and mechanical requirements. Voltage ratings of 20V in substitute parts are not equivalent to the 28V requirement of the main part and represent derating conditions. The MN12SS1G03 from NKK Switches is the manufacturer-recommended direct replacement.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: MN12SS1G03 (NKK Switches)

The MN12SS1G03 is the manufacturer-recommended replacement from NKK Switches. As an active product with ROHS3 compliance, it provides direct continuity with the original design intent. This part is preferred for new designs and production transitions from the obsolete M2012SS1G03.

Secondary Recommendations: 100SP1T1B1M2REH, 1825192-2, 5236CDB, 7101SYCBE

All five substitute parts are active products with ROHS3 compliance and meet the core electrical and mechanical requirements. Selection among these alternatives depends on application voltage requirements and electrical life expectations:

• 100SP1T1B1M2REH (E-Switch): Rated for 20V AC/DC with 40,000 cycle electrical life. Suitable for applications operating below 20V.
• 1825192-2 (TE Connectivity ALCOSWITCH): Rated for 20V AC/DC with extended 80,000 cycle electrical life. Recommended for high-cycle applications below 20V.
• 5236CDB (APEM): Rated for 20V AC/DC with 50,000 cycle electrical life and extended operating temperature range (-40°C to 85°C). Suitable for extreme temperature environments below 20V.
• 7101SYCBE (C&K): Rated for 20V AC/DC with highest electrical life rating of 100,000 cycles. Recommended for maximum cycle durability below 20V.

All substitute parts feature identical circuit configuration (SPDT On-On), current rating (0.4VA AC/DC), mounting type (Panel Mount), termination style (PC Pin), and bushing thread (1/4-40) as the main part.

Frequently Asked Questions (FAQ)

Q: Can the M2012SS1G03 be directly replaced with a 20V-rated substitute in a 28V application?

A: No. The M2012SS1G03 is rated for 28V AC/DC operation. Substitute parts rated for 20V AC/DC operate below the original voltage specification and are not direct equivalents for 28V applications. Application voltage requirements must be verified before substitution.

Q: What is the difference between MN12SS1G03 and M2012SS1G03?

A: The MN12SS1G03 is the active product replacement from NKK Switches for the obsolete M2012SS1G03. Both are from the same manufacturer and share the same base product number (M2012SS). The MN12SS1G03 is recommended as the primary substitute.

Q: Are all substitute parts mechanically compatible with the original panel cutout?

A: Panel cutout diameters vary slightly among substitutes (6.35mm to 6.50mm). The 6.50mm cutout of the main part accommodates the 6.35mm and 6.40mm diameter substitutes. Verify panel cutout dimensions during installation to ensure proper fit and sealing.

Q: Which substitute part has the longest electrical life?

A: The 7101SYCBE (C&K) offers the highest electrical life rating at 100,000 cycles, compared to 50,000 cycles for the main part. The 1825192-2 (TE Connectivity) provides 80,000 cycles.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed are ROHS3 compliant, matching the compliance status of the M2012SS1G03.

Q: What packaging options are available for substitute parts?

A: MN12SS1G03 is available in Bulk packaging. E-Switch 100SP1T1B1M2REH, TE Connectivity 1825192-2, and C&K 7101SYCBE are supplied in Bulk packaging. APEM 5236CDB is supplied in Tray packaging.
