Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M2013SS1W01 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration: SPDT
• Switch function: On-Off-On (preferred) or On-On (acceptable with functional verification)
• Current rating: Minimum 6A AC or equivalent DC rating
• Voltage rating: Minimum 125V AC or equivalent DC rating
• Mounting type: Panel Mount
• Actuator type: Standard Round
• Termination style: Solder Lug
• Bushing thread: 1/4-40
• Panel cutout diameter: 6.35mm to 6.50mm (mechanical fit tolerance)

Secondary Compatibility Factors:

• Operating temperature range: -30°C minimum, 85°C maximum
• RoHS compliance: ROHS3 Compliant preferred
• Actuator length: 10.40mm to 10.67mm (functional tolerance)

Substitute parts are grouped into two categories: direct equivalents (matching all primary criteria) and functional alternatives (meeting electrical and mechanical requirements with minor parameter variations).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Recommended Primary Substitute): The MN13SS1W01 from NKK Switches is the manufacturer-recommended equivalent. As an active product from the same manufacturer, it provides the highest assurance of form, fit, and function compatibility. Detailed electrical specifications are not provided in available documentation; direct consultation with NKK Switches is recommended for complete parameter verification.

Full Electrical & Mechanical Equivalents: The 5639A (APEM Inc.) and MTA106E (TE Connectivity ALCOSWITCH Switches) provide complete electrical and mechanical compatibility with the M2013SS1W01. Both parts match the 6A AC / 125V AC rating, 30V DC voltage capability, 6.50mm panel cutout diameter, and On-Off-On switch function. Both are ROHS3 compliant and active products. The 5639A offers extended operating temperature range (-40°C to 85°C) and higher electrical life (50,000 cycles). The MTA106E provides the highest electrical life rating (60,000 cycles) among all substitutes.

Functional Alternatives (Reduced Current/Voltage Ratings): The 100SP3T1B1M1QEH (E-Switch), 2M1-SP3-T1-B1-M1QE (Carling Technologies), and 7103SYZQE (C&K) are functionally compatible but with reduced current ratings (5A AC instead of 6A AC). These parts are suitable for applications where the full 6A AC rating is not required. The 2M1-SP3-T1-B1-M1QE offers enhanced ingress protection (IP67 - Dust Tight, Waterproof) and higher electrical life (50,000 cycles). All three are ROHS3 compliant and active products.

Functional Alternative (Modified Switch Function): The A121S1YZQ (Electroswitch) provides electrical equivalence with 6A AC / 125V AC rating but features On-On switch function instead of On-Off-On. This part is suitable only for applications where the On-On configuration is functionally acceptable. It offers the highest electrical life rating (60,000 cycles) and extended operating temperature range (-30°C to 90°C). RoHS compliance is stated as "RoHS Compliant" without specific version designation.

Compliance Considerations: All substitute parts maintain ROHS3 compliance or equivalent RoHS certification. The 7103SYZQE (C&K) and MTA106E (TE Connectivity) are flagged as REACH Affected; applications subject to REACH regulations require verification of specific substance compliance documentation from manufacturers.

Frequently Asked Questions (FAQ)

Q: Can the MN13SS1W01 be used as a direct replacement for the M2013SS1W01? A: Yes. The MN13SS1W01 is the manufacturer-recommended equivalent from NKK Switches. As an active product, it is the preferred substitute for the obsolete M2013SS1W01. Detailed electrical specifications should be confirmed with NKK Switches documentation.

Q: What is the difference between the 5639A and MTA106E substitutes? A: Both provide full electrical and mechanical compatibility with 6A AC / 125V AC ratings and On-Off-On function. The 5639A (APEM) offers a wider operating temperature range (-40°C to 85°C) and 50,000 cycle electrical life. The MTA106E (TE Connectivity) provides 60,000 cycle electrical life. Selection depends on specific application temperature and cycle requirements.

Q: Can I use the 100SP3T1B1M1QEH as a substitute if my application only requires 5A AC? A: Yes. The 100SP3T1B1M1QEH (E-Switch) is electrically and mechanically compatible for applications rated at 5A AC or lower. It maintains the same 125V AC voltage rating, SPDT circuit, On-Off-On function, and panel mount configuration. Verify that your application current draw does not exceed 5A AC.

Q: What is the significance of the IP67 rating on the 2M1-SP3-T1-B1-M1QE? A: The 2M1-SP3-T1-B1-M1QE (Carling Technologies) provides IP67 ingress protection (Dust Tight, Waterproof), whereas the M2013SS1W01 does not specify ingress protection. This enhanced protection is beneficial for applications exposed to moisture or dust environments. All other electrical and mechanical parameters remain compatible.

Q: Why does the A121S1YZQ have an On-On function instead of On-Off-On? A: The A121S1YZQ (Electroswitch) is configured for On-On switching, meaning both positions are active. The M2013SS1W01 is configured for On-Off-On, with a neutral center position. The A121S1YZQ is suitable only for applications where the On-On configuration is functionally acceptable. Verify circuit design compatibility before substitution.

Q: Are all substitute parts ROHS3 compliant? A: Most substitute parts are ROHS3 compliant. The A121S1YZQ is listed as "RoHS Compliant" without specific version designation. The 7103SYZQE and MTA106E are flagged as REACH Affected. For applications requiring specific RoHS version certification or REACH compliance, consult manufacturer documentation.

Q: What panel cutout diameter tolerance should I consider for mechanical fit? A: The M2013SS1W01 specifies a 6.50mm circular panel cutout. Substitute parts range from 6.35mm to 6.50mm. The 5639A and MTA106E match the 6.50mm specification exactly. The E-Switch, Carling, and C&K parts specify 6.35mm, which is within standard mechanical tolerance for panel mount switches. Verify panel cutout dimensions in your design before substitution.

Q: Which substitute offers the longest electrical life? A: The A121S1YZQ (Electroswitch) and MTA106E (TE Connectivity) both offer 60,000 cycle electrical life, compared to the M2013SS1W01 specification of 25,000 cycles. For applications requiring extended operational life, either part provides enhanced durability.
