Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit configuration (SPDT required)
• Switch function (On-On required)
• Mounting type (Panel Mount required)
• Actuator type (Standard Round required)
• Bushing thread (1/4-40 required)
• Panel cutout diameter tolerance (6.35mm to 6.50mm acceptable)

Electrical Performance Parameters:

• Current rating must meet or exceed 6A AC / 4A DC
• Voltage rating must meet or exceed 125V AC / 30V DC
• Operating temperature range must encompass -30°C to 85°C

Termination Consideration:

• Solder lug termination is preferred for direct replacement; PC pin termination requires circuit board redesign

Compliance Parameters:

• RoHS3 compliance required for new designs
• REACH status noted for regulatory tracking

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: MN12S2S1W01 (NKK Switches)

The MN12S2S1W01 is the manufacturer-recommended substitute from NKK Switches. As an active product from the original manufacturer, this part maintains design continuity and is ROHS3 compliant. Insufficient electrical specification data in the provided documentation requires verification against the original M2012S2S1W01 ratings before implementation.

Secondary Recommendation: 5636AB16 (APEM Inc.)

The 5636AB16 provides exact electrical equivalence to the M2012S2S1W01, matching 6A AC / 4A DC current ratings and 125V AC / 30V DC voltage ratings. Solder lug termination enables direct circuit board compatibility. ROHS3 compliance and active product status support new design integration. Operating temperature range extends to -40°C, providing enhanced low-temperature performance. Electrical life of 50,000 cycles exceeds the original specification.

Tertiary Recommendation: 7101MYZQE (C&K)

The 7101MYZQE meets core electrical requirements with 5A AC/DC current rating and 120V AC / 28V DC voltage rating, suitable for applications not requiring the full 6A AC capacity. Solder lug termination ensures direct replacement capability. ROHS3 compliance is confirmed. Electrical life of 100,000 cycles provides extended operational durability. REACH status is affected, requiring regulatory review for specific applications.

Alternative with Termination Consideration: 100SP1T2B1M1QEH (E-Switch)

The 100SP1T2B1M1QEH provides 5A AC/DC current rating and 120V AC / 28V DC voltage rating with solder lug termination. ROHS3 compliance and active product status are confirmed. This part is suitable for applications with reduced current requirements. Electrical life of 40,000 cycles exceeds the original specification.

Not Recommended: MTM106DPC (TE Connectivity ALCOSWITCH)

The MTM106DPC features PC pin termination, requiring circuit board redesign and is not suitable for direct solder lug replacement. RoHS non-compliance disqualifies this part for new designs requiring regulatory compliance. Operating temperature range of -20°C to 80°C does not encompass the original -30°C lower limit. REACH status is affected.

Frequently Asked Questions (FAQ)

Q: Can the MN12S2S1W01 be used as a direct replacement for the M2012S2S1W01?

A: The MN12S2S1W01 is the manufacturer-recommended substitute from NKK Switches. Electrical specifications for the MN12S2S1W01 are not fully detailed in the provided documentation. Verification against the original M2012S2S1W01 ratings is required before implementation to confirm current and voltage rating equivalence.

Q: Which substitute part provides the closest electrical match to the M2012S2S1W01?

A: The 5636AB16 from APEM Inc. provides exact electrical equivalence, matching 6A AC / 4A DC current ratings and 125V AC / 30V DC voltage ratings. Solder lug termination enables direct circuit board compatibility without redesign.

Q: Are all substitute parts ROHS3 compliant?

A: Five of the six substitute parts are ROHS3 compliant. The MTM106DPC from TE Connectivity is RoHS non-compliant and is not suitable for applications requiring regulatory compliance.

Q: What is the significance of termination style differences?

A: The M2012S2S1W01 uses solder lug termination. Substitute parts with solder lug termination (MN12S2S1W01, 100SP1T2B1M1QEH, 5636AB16, 7101MYZQE) enable direct circuit board replacement. The MTM106DPC uses PC pin termination, requiring circuit board redesign and is not recommended for direct replacement.

Q: Can parts with lower current ratings be used in applications designed for 6A AC?

A: Substitution with lower current-rated parts (100SP1T2B1M1QEH and 7101MYZQE at 5A AC) is only permissible if the actual circuit current draw does not exceed the substitute part's rating. System-level current analysis is required to confirm compatibility.

Q: What is the impact of different panel cutout diameters?

A: Panel cutout diameters range from 6.35mm to 6.50mm across substitute parts. Existing panel cutouts designed for 6.50mm (M2012S2S1W01 and 5636AB16) accommodate parts with 6.35mm or 6.40mm diameters. Reverse compatibility (6.35mm cutout with 6.50mm part) is not feasible without panel modification.

Q: How do electrical life ratings affect part selection?

A: The M2012S2S1W01 specifies 25,000 electrical cycles. All substitute parts exceed this specification, ranging from 40,000 to 100,000 cycles. Higher electrical life ratings provide extended operational durability but do not affect direct substitution eligibility.

Q: Are there temperature range limitations with substitute parts?

A: The M2012S2S1W01 operates from -30°C to 85°C. The 5636AB16 extends the lower limit to -40°C. The MTM106DPC limits the lower range to -20°C, making it unsuitable for applications requiring -30°C operation. All other substitutes maintain the -30°C lower limit.
