MB2011LS1A01-CC Equivalent & Substitute Parts

Part Overview

The MB2011LS1A01-CC 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, making equivalent substitute parts necessary for ongoing design support and procurement continuity. The switch employs panel mount rear termination with solder lug connections and operates across -30°C to 85°C with 100,000 mechanical cycles and 25,000 electrical cycles rated life.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2011LS1A01-CC is determined by the following critical parameters:

Mandatory Matching Parameters:

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

Allowable Variation Parameters:

• DC current rating: Substitute must meet or exceed 3A DC
• DC voltage rating: Substitute must meet or exceed 30V DC
• Panel cutout diameter: Circular configuration with tolerance for mechanical fit
• Operating temperature range: Substitute may have narrower range if application requirements permit
• Mechanical and electrical life: Substitute values may differ based on application duty cycle

The substitute parts MPA106F and MPE106F from TE Connectivity ALCOSWITCH Switches meet all mandatory matching parameters. Both maintain SPDT circuit configuration, On-Mom function, 6A AC rating at 125V AC, panel mount rear configuration, and solder lug termination. Both exceed the DC current requirement (4A vs. 3A) and approach the DC voltage specification (28V vs. 30V). Panel cutout diameter variation (6.35mm vs. 6.50mm) falls within acceptable mechanical tolerance for standard panel mount applications.

Parameter Comparison

Engineering Selection Recommendations

Both MPA106F and MPE106F are active product alternatives to the obsolete MB2011LS1A01-CC. Selection between these two substitutes should be based on application environmental requirements:

MPA106F Selection Criteria:

• Standard environmental conditions without splash or moisture exposure
• Applications requiring baseline SPDT momentary switching functionality
• Cost-optimized procurement for general industrial control applications
• ROHS3 compliance with vendor-undefined REACH status

MPE106F Selection Criteria:

• Applications requiring splash-proof ingress protection
• Environments with potential moisture or liquid exposure
• Enhanced environmental durability requirements
• ROHS3 compliance with REACH Affected designation

Both substitutes provide superior electrical life (50,000 cycles vs. 25,000 cycles) compared to the original part. The operating temperature range narrowing (-20°C to 80°C vs. -30°C to 85°C) requires verification against specific application temperature requirements. DC voltage specification (28V vs. 30V) represents a 6.7% reduction and should be evaluated for margin-critical DC applications.

Frequently Asked Questions (FAQ)

Q: Can MPA106F and MPE106F be used interchangeably with MB2011LS1A01-CC?

A: Both parts meet the core electrical and mechanical requirements for SPDT momentary switching at 6A AC / 125V AC. Panel cutout diameter variation (6.35mm vs. 6.50mm) is within standard mechanical tolerance for panel mount applications. Operating temperature range and DC voltage specifications differ slightly and must be evaluated against specific application requirements.

Q: What is the difference between MPA106F and MPE106F?

A: The primary difference is ingress protection. MPE106F provides splash-proof protection, while MPA106F offers standard environmental sealing. Both share identical electrical ratings, circuit configuration, and mounting specifications. MPE106F carries REACH Affected designation versus MPA106F's vendor-undefined REACH status.

Q: Does the 6.35mm panel cutout diameter of the substitutes affect installation?

A: The 0.15mm reduction in cutout diameter (from 6.50mm to 6.35mm) falls within standard mechanical tolerance for panel mount switches. Existing panel cutouts designed for 6.50mm will accommodate 6.35mm diameter components. Verify panel thickness and mounting hardware compatibility with rear panel mount configuration.

Q: Are there compliance concerns when substituting to MPA106F or MPE106F?

A: Both substitutes maintain ROHS3 compliance equivalent to the original part. MPE106F carries REACH Affected status requiring compliance verification in regulated markets, while MPA106F shows vendor-undefined REACH status. Both parts carry EAR99 ECCN classification matching the original component.

Q: How does the reduced DC voltage rating (28V vs. 30V) affect suitability?

A: The 28V DC rating of both substitutes represents a 6.7% reduction from the original 30V specification. Applications operating at or near 30V DC maximum should be evaluated for adequate margin. Applications operating below 28V DC are unaffected. Verify actual operating voltage against design specifications.

Q: What is the impact of the narrower operating temperature range?

A: Both substitutes operate from -20°C to 80°C versus the original -30°C to 85°C range. Applications requiring operation below -20°C or above 80°C are not suitable for these substitutes. Verify actual operating environment temperature extremes against application requirements.
