MB2011LD3W01/M-CH Equivalent & Substitute Parts

Part Overview

The MB2011LD3W01/M-CH 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 active equivalent parts for new designs and ongoing production requirements. The switch is designed for panel mount rear installation with IP67 ingress protection and epoxy sealed terminals, suitable for applications requiring dust-tight and waterproof operation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2011LD3W01/M-CH is determined by the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: SPDT
• Switch function: On-Mom (momentary)
• Termination style: Solder Lug
• Mounting type: Panel Mount, Rear
• AC voltage rating: 125V minimum
• AC current rating: 6A minimum
• Mechanical compatibility: Panel cutout diameter within acceptable tolerance

Acceptable Parameter Variations:

• DC voltage rating: Substitute may exceed 30V (higher rating acceptable)
• DC current rating: Substitute may exceed 3A (higher rating acceptable)
• Operating temperature range: Substitute may have narrower range if it encompasses the application's operating conditions
• Ingress protection: Substitute may exceed IP67 (higher protection acceptable)
• Electrical life: Substitute may differ from 25,000 cycles if application requirements are met

The identified substitutes MPA106F and MPE106F from TE Connectivity ALCOSWITCH Switches meet all mandatory parameters. Both parts maintain SPDT circuit configuration, On-Mom function, solder lug termination, panel mount rear installation, 125V AC rating, and 6A AC current rating. Panel cutout diameter of 6.35mm is compatible with standard 6.50mm specifications through normal mechanical tolerance practices.

Parameter Comparison

Engineering Selection Recommendations

Both MPA106F and MPE106F are active products from TE Connectivity ALCOSWITCH Switches and serve as functional equivalents to the obsolete MB2011LD3W01/M-CH. Selection between these two substitutes should be based on the following criteria:

MPA106F Selection Criteria:

• Applications where ingress protection specification is not explicitly required
• Designs where RoHS3 compliance is mandatory
• Standard environmental conditions without splash or water exposure requirements

MPE106F Selection Criteria:

• Applications requiring splash-proof ingress protection
• Designs where enhanced environmental protection is specified
• Environments with potential moisture or liquid exposure
• RoHS3 compliance requirement

Both substitutes provide superior electrical life (50,000 cycles versus 25,000 cycles) and higher DC current ratings (4A versus 3A), offering improved performance margins over the original part. The narrower operating temperature range (-20°C to 80°C versus -30°C to 85°C) must be evaluated against specific application requirements. Both parts maintain ROHS3 compliance, supporting modern regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can MPA106F or MPE106F be used as direct replacements for MB2011LD3W01/M-CH?

A: Yes, both parts are functionally equivalent. They maintain identical SPDT circuit configuration, On-Mom function, 6A AC current rating, 125V AC voltage rating, solder lug termination, and panel mount rear installation. Panel cutout diameter difference (6.35mm versus 6.50mm) is within standard mechanical tolerance for panel mount applications.

Q: What is the difference between MPA106F and MPE106F?

A: The primary difference is ingress protection rating. MPE106F provides splash-proof protection, while MPA106F does not specify ingress protection. Both parts are otherwise electrically and mechanically equivalent. Selection depends on environmental exposure requirements.

Q: Are there any electrical performance differences between the original part and substitutes?

A: The substitutes provide improved electrical life (50,000 cycles versus 25,000 cycles) and higher DC current rating (4A versus 3A). DC voltage rating is slightly lower (28V versus 30V), which is acceptable for most applications. Operating temperature range is narrower (-20°C to 80°C versus -30°C to 85°C).

Q: Do the substitute parts meet modern compliance requirements?

A: Yes, both MPA106F and MPE106F are ROHS3 compliant. MPE106F is REACH Affected, while MPA106F has undefined REACH status. Verify REACH compliance requirements for your specific application and region.

Q: Is the 0.15mm panel cutout diameter difference significant?

A: No. Standard panel mount switch installation tolerances accommodate this difference. The 6.35mm cutout of the substitute parts is compatible with panels designed for 6.50mm diameter openings through normal mechanical tolerance practices.

Q: What is the inventory status of these substitute parts?

A: MPA106F has 1,578 pieces in stock, and MPE106F has 1,039 pieces in stock, both available as new original components in bulk packaging.
