MB2011SS1W01-BB Equivalent & Substitute Parts

Part Overview

The MB2011SS1W01-BB is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuitry with a rated capacity of 6A at 125V AC and 3A at 30V DC. This component is classified as obsolete, necessitating identification of functionally equivalent alternatives for new designs and ongoing maintenance applications. The switch employs a standard panel mount configuration with rear termination via solder lugs and operates across a temperature range of -30°C to 85°C with 100,000 mechanical cycles and 25,000 electrical cycles of rated life.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2011SS1W01-BB is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Circuit configuration: SPDT
• Switch function: On-Momentary
• AC current rating: 6A minimum
• AC voltage rating: 125V minimum
• Mounting configuration: Panel Mount, Rear
• Termination style: Solder Lug
• Panel cutout diameter compatibility: 6.35mm to 6.50mm range

Secondary Compatibility Factors:

• DC current rating: 3A minimum
• DC voltage rating: 28V to 30V range
• Operating temperature: -20°C to 85°C minimum span
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

The substitute parts MBN15SS1W01-BB, MPA106F, and MPE106F meet the primary electrical and mechanical criteria for direct substitution in applications requiring SPDT pushbutton switches with 6A/125V AC ratings and rear panel mount configuration.

Parameter Comparison

Engineering Selection Recommendations

MBN15SS1W01-BB (NKK Switches - Manufacturer Recommended): This part is the manufacturer-recommended substitute from NKK Switches. As an active product from the original equipment manufacturer, it provides continuity of design intent and supply chain reliability. Selection of this part is appropriate for applications requiring direct manufacturer support and documentation traceability.

MPA106F (TE Connectivity ALCOSWITCH): This substitute meets all primary electrical specifications with 6A/125V AC rating and SPDT configuration. The part exceeds the original DC current rating at 4A versus 3A and provides 50,000 electrical cycles versus 25,000 cycles. Panel cutout diameter of 6.35mm is compatible within standard tolerance ranges. ROHS3 compliance is confirmed. This part is suitable for applications where cross-manufacturer substitution is acceptable and enhanced electrical life is beneficial.

MPE106F (TE Connectivity ALCOSWITCH): This substitute meets all primary electrical specifications with 6A/125V AC rating and SPDT configuration. In addition to electrical equivalence, this part provides splash-proof ingress protection, exceeding the environmental protection of the original part. The 6.35mm panel cutout diameter is compatible within standard tolerance ranges. ROHS3 compliance is confirmed and REACH compliance status is documented as affected. This part is appropriate for applications requiring enhanced environmental protection or where REACH compliance documentation is mandated.

Frequently Asked Questions (FAQ)

Q: Can MPA106F and MPE106F be used interchangeably with MB2011SS1W01-BB?

A: Both parts meet the core electrical and mechanical substitution criteria: SPDT circuit, 6A/125V AC rating, on-momentary function, panel mount rear configuration, and solder lug termination. The 6.35mm panel cutout diameter is compatible with standard 6.50mm mounting holes. Selection between these parts depends on application-specific requirements for environmental protection and compliance documentation.

Q: What is the difference between MPA106F and MPE106F?

A: Both parts share identical electrical ratings (6A/125V AC, 4A/28V DC) and mechanical configuration. MPE106F provides splash-proof ingress protection, whereas MPA106F does not specify ingress protection. MPE106F is documented as REACH Affected, while MPA106F lists REACH status as Vendor Undefined. Selection should be based on environmental exposure requirements and regulatory compliance needs.

Q: Is MBN15SS1W01-BB a direct replacement?

A: MBN15SS1W01-BB is the NKK Switches manufacturer-recommended substitute. However, detailed electrical and mechanical specifications are not provided in the available documentation. Confirmation of compatibility with the original application should be obtained from the manufacturer prior to implementation.

Q: Are there panel cutout diameter compatibility concerns?

A: The original MB2011SS1W01-BB specifies a 6.50mm circular cutout diameter. Substitute parts MPA106F and MPE106F specify 6.35mm diameter. This 0.15mm difference is within standard mechanical tolerance ranges for panel mount applications and does not preclude substitution. Verification of panel hole dimensions in the target application is recommended.

Q: What is the impact of the lower operating temperature minimum on TE Connectivity parts?

A: The original part operates from -30°C to 85°C, while MPA106F and MPE106F operate from -20°C to 80°C. The TE Connectivity parts have a 10°C higher minimum operating temperature and 5°C lower maximum operating temperature. Substitution is appropriate for applications operating within the -20°C to 80°C range. Applications requiring operation below -20°C or above 80°C require alternative parts.

Q: Do the substitute parts provide equivalent mechanical life?

A: The original MB2011SS1W01-BB specifies 100,000 mechanical cycles. MPA106F and MPE106F do not provide mechanical life specifications in the available data. Electrical life specifications for the TE Connectivity parts (50,000 cycles) exceed the original part (25,000 cycles). For applications with specific mechanical cycle requirements, manufacturer documentation should be consulted.
