Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M2012ES4W01 is determined by the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-On)
• Current and voltage ratings (6A AC / 125V, 4A DC / 30V)
• Mounting type (Panel Mount)
• Termination style (Solder Lug)
• Panel cutout and bushing dimensions (Circular 6.50mm, M6 x 0.75)
• Operating temperature range (-30°C to 85°C)
• Electrical life rating (25,000 Cycles)

The substitute part MN12ES4W01 is classified as an equivalent based on manufacturer designation and maintains compatibility with the electrical and mechanical interface requirements of the original specification.

Parameter Comparison

Engineering Selection Recommendations

The MN12ES4W01 is designated as the manufacturer-recommended substitute for the obsolete M2012ES4W01. Both parts are manufactured by NKK Switches and share identical ECCN and HTSUS classifications, confirming regulatory alignment.

The M2012ES4W01 is ROHS3 compliant. The MN12ES4W01 maintains active product status, ensuring ongoing availability and supply chain support. Selection of the MN12ES4W01 is appropriate for applications requiring continuity with the original M2012ES4W01 specification where the electrical and mechanical parameters remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can the MN12ES4W01 directly replace the M2012ES4W01 in existing designs?

A: The MN12ES4W01 is the manufacturer-designated equivalent. Direct replacement is appropriate provided the electrical ratings (6A AC / 125V, 4A DC / 30V), circuit configuration (SPDT), mounting type (Panel Mount), and mechanical interface (M6 x 0.75 bushing, 6.50mm circular cutout) remain compatible with the application requirements.

Q: What is the significance of the product status difference between these parts?

A: The M2012ES4W01 is classified as obsolete, indicating discontinued manufacturing. The MN12ES4W01 maintains active status, confirming current production and availability. This distinction supports long-term supply chain planning and procurement strategy.

Q: Are there packaging differences between these parts?

A: The M2012ES4W01 packaging specification is not provided. The MN12ES4W01 is supplied in bulk packaging. Packaging requirements should be evaluated based on specific procurement and assembly processes.

Q: Do both parts meet the same regulatory requirements?

A: Both parts share identical ECCN (EAR99) and HTSUS (8536.50.9065) classifications. The M2012ES4W01 is confirmed ROHS3 compliant. Regulatory compliance status for the MN12ES4W01 should be verified with the manufacturer if required for specific applications.

Q: What electrical parameters must remain constant for substitution?

A: Critical electrical parameters include circuit configuration (SPDT), switch function (On-On), current ratings (6A AC, 4A DC), voltage ratings (125V AC, 30V DC), and electrical life (25,000 cycles). Any deviation from these specifications requires engineering evaluation.
