Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MB2011SD3W01-CA are identified based on the following critical parameters that determine functional equivalence:

Mandatory Matching Parameters:

• Circuit configuration: SPDT
• Switch function: On-Mom (Momentary)
• Current rating: 6A AC minimum
• Voltage rating: 125V AC minimum
• Mounting type: Panel Mount, Rear
• Termination style: Solder Lug
• RoHS compliance: ROHS3 Compliant

Acceptable Variation Parameters:

• DC current rating: May exceed 3A (substitute parts rated 4A DC are acceptable)
• DC voltage rating: May differ from 30V (substitute parts rated 28V DC are acceptable)
• Panel cutout diameter: Circular 6.35mm is compatible with 6.50mm requirement
• Operating temperature range: Narrower range acceptable if minimum -20°C and maximum 80°C are met
• Ingress protection: IP67 or Splash Proof both acceptable for sealed terminal applications

The substitute parts MPA106F and MPE106F from TE Connectivity ALCOSWITCH Switches meet these criteria and are classified as active products, providing supply continuity for the obsolete MB2011SD3W01-CA.

Parameter Comparison

Engineering Selection Recommendations

Both MPA106F and MPE106F are suitable substitutes for the obsolete MB2011SD3W01-CA based on electrical and mechanical parameter alignment. Selection between the two TE Connectivity alternatives should consider the following factors:

MPA106F Selection Criteria:

• Active product status with established supply chain
• ROHS3 compliant
• Meets all mandatory electrical parameters (6A AC, 125V AC, SPDT, On-Mom)
• DC current rating of 4A exceeds original 3A specification
• Panel cutout diameter 6.35mm compatible with 6.50mm requirement
• REACH status listed as Vendor Undefined

MPE106F Selection Criteria:

• Active product status with established supply chain
• ROHS3 compliant
• Meets all mandatory electrical parameters (6A AC, 125V AC, SPDT, On-Mom)
• DC current rating of 4A exceeds original 3A specification
• Panel cutout diameter 6.35mm compatible with 6.50mm requirement
• Splash Proof ingress protection provides enhanced environmental sealing
• REACH Affected status indicates full regulatory documentation availability

MPE106F provides additional environmental protection through Splash Proof rating, making it the preferred choice for applications requiring enhanced moisture resistance beyond standard sealed terminal design.

Frequently Asked Questions (FAQ)

Q: Can MPA106F or MPE106F be used as direct replacements for MB2011SD3W01-CA?

A: Yes. Both parts meet the mandatory electrical specifications (SPDT circuit, 6A AC / 125V AC, On-Mom function, Solder Lug termination) and mechanical mounting requirements (Panel Mount, Rear). The 6.35mm panel cutout diameter is compatible with the original 6.50mm specification.

Q: What is the difference between MPA106F and MPE106F?

A: Both parts share identical electrical ratings and mounting specifications. The primary difference is ingress protection: MPE106F provides Splash Proof rating, while MPA106F does not specify ingress protection. For applications requiring enhanced environmental sealing, MPE106F is the appropriate selection.

Q: Are there any temperature range limitations when substituting these parts?

A: The substitute parts operate within -20°C to 80°C, which is narrower than the original MB2011SD3W01-CA range of -30°C to 85°C. Applications requiring operation below -20°C or above 80°C cannot use these substitutes.

Q: Do the substitute parts maintain RoHS3 compliance?

A: Yes. Both MPA106F and MPE106F are ROHS3 compliant, matching the compliance status of the original MB2011SD3W01-CA.

Q: What is the DC current rating difference, and does it affect compatibility?

A: The substitute parts are rated 4A DC compared to the original 3A DC rating. This higher rating is acceptable and does not create compatibility issues. Applications designed for 3A DC operation will function within the substitute parts' specifications.

Q: Are panel cutout modifications required for installation?

A: The substitute parts require a 6.35mm circular panel cutout compared to the original 6.50mm specification. Existing panel cutouts at 6.50mm will accommodate the 6.35mm diameter without modification, though clearance will be slightly increased.
