Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2011SS1A01-BA is determined by the following critical parameters:

Mandatory Matching Criteria:

• Circuit configuration: SPDT
• Switch function: On-Mom
• AC current rating: 6A minimum
• AC voltage rating: 125V minimum
• Mounting type: Panel Mount, Rear
• Termination style: Solder Lug

Allowable Variations:

• DC current rating: Substitute must meet or exceed 3A
• DC voltage rating: Substitute must meet or exceed 30V
• Panel cutout diameter: Circular configuration with tolerance for mechanical fit
• Operating temperature range: Substitute may have narrower range if application requirements are met
• Electrical life: Substitute may differ from original specification
• Actuator type: Functional equivalence maintained with different actuator designs

The substitute parts MPA106F and MPE106F from TE Connectivity ALCOSWITCH Switches meet all mandatory matching criteria and are classified as active products, providing supply continuity for the obsolete MB2011SS1A01-BA.

Parameter Comparison

Engineering Selection Recommendations

Both MPA106F and MPE106F are suitable substitutes for the obsolete MB2011SS1A01-BA based on electrical and mechanical compatibility. Selection between the two substitute options should consider the following factors:

MPA106F Selection Criteria:

• Standard ingress protection level
• Active product status with established supply chain
• ROHS3 compliant with MSL 1 rating
• Electrical life rating of 50,000 cycles exceeds original specification

MPE106F Selection Criteria:

• Splash Proof ingress protection provides enhanced environmental protection
• Active product status with established supply chain
• ROHS3 compliant with MSL 1 rating
• REACH Affected status requires compliance verification for specific applications
• Electrical life rating of 50,000 cycles exceeds original specification

Both substitutes demonstrate superior electrical life performance compared to the original component. Panel cutout diameter reduction from 6.50mm to 6.35mm requires mechanical fit assessment for existing panel installations. Operating temperature range narrowing from -30°C to 85°C to -20°C to 80°C must be evaluated against application requirements.

Frequently Asked Questions (FAQ)

Q: Can MPA106F and MPE106F be used interchangeably with MB2011SS1A01-BA?

A: Both parts meet the mandatory electrical and mechanical criteria for substitution. MPA106F provides standard functionality, while MPE106F offers additional Splash Proof ingress protection. Selection depends on environmental exposure requirements and REACH compliance obligations.

Q: What is the impact of the panel cutout diameter difference (6.50mm vs 6.35mm)?

A: The 0.15mm reduction in panel cutout diameter for substitute parts may require mechanical fit assessment. Existing panel installations designed for 6.50mm diameter may accommodate the smaller 6.35mm cutout, but physical verification is necessary for specific applications.

Q: Are there compliance differences between the substitute parts?

A: Both MPA106F and MPE106F are ROHS3 compliant with MSL 1 rating. MPE106F carries REACH Affected status, requiring compliance verification for applications subject to REACH regulations. MPA106F lists REACH status as Vendor Undefined.

Q: How do the electrical life ratings compare?

A: The original MB2011SS1A01-BA specifies 25,000 electrical cycles. Both substitute parts (MPA106F and MPE106F) provide 50,000 electrical cycles, representing a 100% improvement in rated electrical life.

Q: What is the significance of the DC voltage rating difference (30V vs 28V)?

A: The substitute parts specify 28V DC rating compared to the original 30V DC rating. Applications operating at or below 28V DC are fully compatible. Applications requiring operation above 28V DC must be evaluated for alternative solutions.

Q: Does the operating temperature range difference affect substitution?

A: The substitute parts operate from -20°C to 80°C compared to the original -30°C to 85°C range. Applications within the -20°C to 80°C window are fully compatible. Applications requiring extended temperature operation must be evaluated separately.
