MB2011SS1W01/U Equivalent & Substitute Parts

Part Overview

The MB2011SS1W01/U is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with 6A AC and 3A DC current ratings at 125V AC and 30V DC respectively. This component is classified as obsolete, necessitating identification of equivalent substitute parts for ongoing design requirements and procurement needs. The switch employs a plunger actuator with solder lug termination and is rated for 100,000 mechanical cycles and 25,000 electrical cycles.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MB2011SS1W01/U are qualified based on the following critical parameters:

Electrical Compatibility: Circuit configuration (SPDT), switch function (On-Mom), AC voltage rating (125V minimum), and AC current rating (6A minimum) must be maintained or exceeded.

Mechanical Compatibility: Mounting type (Panel Mount, Rear), actuator type (Plunger for Cap), and termination style (Solder Lug) must be identical.

Physical Compatibility: Panel cutout dimensions must accommodate the original 6.50mm circular cutout or be compatible with standard panel modifications.

Regulatory Compliance: RoHS3 compliance is required for equivalent substitution.

The substitute parts MPA106F and MPE106F, both manufactured by TE Connectivity ALCOSWITCH Switches, meet these criteria with the following considerations: both maintain SPDT configuration, On-Mom function, 6A AC rating, 125V AC voltage, Panel Mount Rear configuration, Plunger actuator, and Solder Lug termination. Both are RoHS3 compliant and currently active products.

Parameter Comparison

Engineering Selection Recommendations

Both MPA106F and MPE106F are qualified substitutes for the MB2011SS1W01/U based on electrical and mechanical parameter alignment. Selection between the two substitute options depends on application-specific requirements:

MPA106F is suitable for standard applications where the specified electrical and mechanical parameters are sufficient. This part maintains active product status with ROHS3 compliance and provides extended electrical life (50,000 cycles versus 25,000 cycles).

MPE106F is appropriate for applications requiring enhanced environmental protection. This part includes Splash Proof ingress protection classification and maintains all other electrical and mechanical equivalencies. REACH Affected status indicates regulatory tracking requirements for this variant.

Both substitutes operate within narrower temperature ranges (-20°C to 80°C) compared to the original part (-30°C to 85°C). Panel cutout diameter reduction from 6.50mm to 6.35mm requires panel modification or adapter consideration for direct mechanical replacement.

Frequently Asked Questions (FAQ)

Q: Can MPA106F and MPE106F be used interchangeably with MB2011SS1W01/U?

A: Both parts meet the core electrical requirements (SPDT, 6A AC, 125V AC, On-Mom function) and mechanical specifications (Panel Mount Rear, Plunger actuator, Solder Lug termination). Panel cutout diameter differs (6.35mm versus 6.50mm), requiring mechanical accommodation. Temperature operating range is narrower in the substitutes. Selection depends on application environmental and temperature requirements.

Q: What is the difference between MPA106F and MPE106F?

A: Both parts are electrically and mechanically equivalent. MPE106F includes Splash Proof ingress protection, making it suitable for applications with moisture exposure. MPE106F carries REACH Affected status, while MPA106F status is Vendor Undefined. MPA106F is the standard option for non-environmental applications.

Q: Are there packaging considerations for these substitutes?

A: Both MPA106F and MPE106F are supplied in Bulk packaging. Original inventory availability is 1,578 pieces for MPA106F and 1,039 pieces for MPE106F.

Q: What compliance certifications apply to these substitutes?

A: All three parts (original and both substitutes) are ROHS3 compliant. Both substitutes carry EAR99 ECCN classification and 8536.50.9035 HTSUS code. Moisture Sensitivity Level is 1 (Unlimited) for all parts.

Q: How do electrical life ratings compare?

A: The original MB2011SS1W01/U is rated for 25,000 electrical cycles. Both MPA106F and MPE106F provide 50,000 electrical cycles, representing a 2x improvement in electrical life expectancy.
