Key Parameters

Substitute Part Grouping Explanation

Substitution of the M2011SS1W01-BB is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPST)
• Current and voltage ratings (6A/125V AC minimum; 4A/30V DC minimum)
• Mounting type (Panel Mount)
• Termination style (Solder Lug)
• Panel cutout dimensions and bushing thread specifications (Circular 6.50mm Dia, 1/4-40)
• Operating temperature range (-30°C to 85°C)
• Compliance certifications (RoHS3, REACH Unaffected, EAR99)

The identified substitute MN11SS1W01-BB maintains electrical and mechanical compatibility within these parameters while offering active product status and current availability.

Parameter Comparison

Engineering Selection Recommendations

The M2011SS1W01-BB is classified as obsolete. The substitute part MN11SS1W01-BB is manufactured by the same supplier (NKK Switches) and carries identical export control and tariff classifications (EAR99, HTSUS 8536.50.9065), indicating functional and regulatory equivalence.

Selection between the main part and substitute should be based on:

• Availability requirements: The main part has 700 units in stock; the substitute has 741 units in stock
• Product lifecycle status: The main part is obsolete; the substitute is active
• Compliance continuity: Both parts maintain RoHS3 compliance and REACH unaffected status

For new designs or long-term system support, the active substitute part MN11SS1W01-BB is the appropriate choice.

Frequently Asked Questions (FAQ)

Q: Can MN11SS1W01-BB be used as a direct replacement for M2011SS1W01-BB?

A: Both parts are manufactured by NKK Switches and share identical export control and tariff classifications. The substitute is designated as an equivalent alternative based on the manufacturer's part substitution list.

Q: What are the key electrical parameters that determine substitutability?

A: The critical parameters are circuit configuration (SPST), current ratings (6A AC / 4A DC), voltage ratings (125V AC / 30V DC), and termination style (Solder Lug). These parameters must remain constant for functional equivalence.

Q: Why is the M2011SS1W01-BB marked as obsolete?

A: Obsolete status indicates the part is no longer in active production. The substitute MN11SS1W01-BB maintains active product status and current manufacturing availability.

Q: Are there packaging differences between the main part and substitute?

A: The main part is specified with "-" packaging notation. The substitute is supplied in Bulk packaging. Verify packaging requirements for your application before procurement.

Q: Do both parts meet the same compliance standards?

A: Both parts carry EAR99 export classification and HTSUS code 8536.50.9065. The main part is RoHS3 compliant; compliance status for the substitute is not specified in the provided data.
