M2015SS1W25 Equivalent & Substitute Parts

Part Overview

The M2015SS1W25 is a toggle switch manufactured by NKK Switches, classified as SPDT (Single Pole Double Throw) with On-Mom functionality. This panel-mount switch is rated for 6A at 125V AC and 3A at 30V DC, featuring a standard round actuator with epoxy sealed terminals. The product is currently obsolete, making equivalent and substitute parts necessary for system maintenance, repair, and legacy equipment support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M2015SS1W25 is determined by the following critical parameters:

• Circuit Configuration: Must be SPDT
• Switch Function: Must be On-Mom
• Current Rating: Must support minimum 6A AC / 3A DC
• Voltage Rating: Must support minimum 125V AC / 30V DC
• Mounting Type: Must be Panel Mount
• Actuator Type: Must be Standard Round
• Panel Cutout Dimensions: Must accommodate Circular 6.50mm Dia
• Bushing Thread: Must be 1/4-40
• Termination Style: Must be PC Pin
• Operating Temperature: Must cover -30°C to 85°C range
• RoHS Compliance: Must meet ROHS3 standard

Two substitute parts meet these criteria: M2015SS1W03 (NKK Switches) and 7108SYV3QE (C&K). Both maintain identical electrical specifications, mechanical compatibility, and regulatory compliance with the original part.

Parameter Comparison

Engineering Selection Recommendations

M2015SS1W03 is a direct equivalent manufactured by NKK Switches with identical electrical and mechanical specifications. Both parts share the same base product number (M2015SS) and differ only in packaging (W25 vs. W03). This substitute maintains full compatibility with the original design and carries ROHS3 compliance. The M2015SS1W03 is also obsolete, making it suitable for legacy system replacement where original stock is unavailable.

7108SYV3QE is a cross-manufacturer substitute from C&K that meets all critical substitution parameters. While AC current rating is reduced to 5A (versus 6A), DC current capability is increased to 5A (versus 3A). AC voltage is rated at 120V (versus 125V) and DC voltage at 28V (versus 30V). The 7108SYV3QE offers extended electrical life of 40,000 cycles compared to 25,000 cycles. This part carries ROHS3 compliance and maintains active product status, ensuring long-term availability. The panel cutout diameter is 6.35mm, which is compatible with the 6.50mm specification through standard panel mounting tolerances.

Selection between these substitutes depends on application current and voltage requirements. For applications requiring the full 6A AC rating, M2015SS1W03 is the appropriate choice. For applications within 5A AC limits, 7108SYV3QE provides enhanced reliability through increased electrical life and active product status.

Frequently Asked Questions (FAQ)

Q: Can M2015SS1W03 be used as a direct replacement for M2015SS1W25?

A: Yes. Both parts are manufactured by NKK Switches with identical electrical ratings (6A AC / 3A DC, 125V AC / 30V DC), mechanical configuration (SPDT On-Mom, panel mount, 1/4-40 bushing), and operating specifications. The parts differ only in packaging designation.

Q: What are the limitations of using 7108SYV3QE as a substitute?

A: The 7108SYV3QE has reduced AC current rating (5A versus 6A) and reduced AC voltage rating (120V versus 125V). Applications requiring the full 6A AC or 125V AC specification must use M2015SS1W03. DC specifications are equivalent or superior (5A DC versus 3A DC, 28V DC versus 30V DC).

Q: Are all three parts mechanically compatible with the same panel cutout?

A: M2015SS1W25 and M2015SS1W03 require identical 6.50mm circular cutouts. The 7108SYV3QE requires a 6.35mm circular cutout. Standard panel mounting tolerances accommodate this 0.15mm difference. Verify panel cutout dimensions before installation.

Q: Do all substitute parts meet current regulatory requirements?

A: Yes. M2015SS1W03 and 7108SYV3QE both carry ROHS3 compliance. The 7108SYV3QE is REACH Affected, while M2015SS1W03 is REACH Unaffected. Both parts are classified under ECCN EAR99 and HTSUS 8536.50.9065.

Q: Which substitute offers the best long-term availability?

A: The 7108SYV3QE maintains active product status with C&K, ensuring continued availability. M2015SS1W03 is obsolete, similar to the original part. For new designs or long-term support requirements, 7108SYV3QE is the recommended choice within its electrical specification limits.

Q: What is the difference in electrical life between the parts?

A: M2015SS1W25 and M2015SS1W03 are rated for 25,000 cycles. The 7108SYV3QE is rated for 40,000 cycles, providing 60% extended operational life.
