Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M2019SS1W01-BA is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-Off-Mom)
• Current and voltage ratings (6A AC / 125V, 4A DC / 30V)
• Mounting type (Panel Mount)
• Actuator specifications (Standard Round with Cap, 10.50mm length)
• Termination style (Solder Lug)
• Panel cutout dimensions (Circular - 6.50mm Dia)
• Bushing thread specification (1/4-40)
• Operating temperature range (-30°C to 85°C)

The substitute part MN19SS1W01-BA meets these electrical and mechanical parameters, establishing functional equivalence for direct replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The MN19SS1W01-BA serves as the direct equivalent for M2019SS1W01-BA applications. Both components are manufactured by NKK Switches and share identical electrical ratings, circuit configuration, and mechanical specifications. The primary distinction is product status: the original part is obsolete while the substitute is active production.

Selection of MN19SS1W01-BA is appropriate for new designs and replacement applications where the M2019SS1W01-BA is no longer available. Both parts carry EAR99 export classification and fall under HTSUS code 8536.50.9065. The original part maintains ROHS3 compliance; compliance status for the substitute should be confirmed through the manufacturer if regulatory requirements mandate this certification.

Frequently Asked Questions (FAQ)

Q: Can MN19SS1W01-BA directly replace M2019SS1W01-BA in existing assemblies?

A: Yes. Both parts share identical SPDT circuit configuration, On-Off-Mom switching function, 6A AC / 4A DC current ratings, 125V AC / 30V DC voltage ratings, panel mount configuration, solder lug termination, and mechanical dimensions. Direct substitution is electrically and mechanically compatible.

Q: What is the difference between these two part numbers?

A: The M2019SS1W01-BA is obsolete; the MN19SS1W01-BA is in active production. Both are NKK Switches products with equivalent electrical and mechanical specifications. The substitute part is available for new procurement and ongoing system support.

Q: Are there packaging differences between these parts?

A: The original part is packaged in standard format; the substitute is supplied in bulk packaging. This distinction affects procurement and inventory management but does not impact electrical or mechanical performance.

Q: Do both parts meet the same compliance standards?

A: Both parts carry EAR99 export classification and HTSUS code 8536.50.9065. The original part is ROHS3 compliant. Compliance certification for the substitute should be verified with the manufacturer if regulatory requirements apply to your application.

Q: What are the critical parameters for substitution?

A: SPDT circuit configuration, On-Off-Mom function, 6A AC at 125V and 4A DC at 30V ratings, panel mount type, standard round actuator with 10.50mm length, solder lug termination, 6.50mm circular panel cutout, and 1/4-40 bushing thread must all match for functional equivalence.
