MB2011LS1A01-CE Equivalent & Substitute Parts

Part Overview

The MB2011LS1A01-CE 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 alternatives for new designs and ongoing production requirements. The part employs panel mount rear termination with solder lug connections and yellow round button actuator, sealed with epoxy terminals for environmental protection.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2011LS1A01-CE 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
• RoHS compliance: ROHS3 Compliant

Allowable Variations:

• DC current rating: Substitute must meet or exceed 3A DC
• DC voltage rating: Substitute must meet or exceed 30V DC
• Panel cutout diameter: Tolerance of ±0.15mm acceptable for standard panel mount applications
• Operating temperature range: Substitute may have narrower range if minimum -20°C and maximum 80°C are maintained
• Electrical life: Substitute may exceed specified cycles
• Mechanical life: Substitute may exceed specified cycles

The identified substitutes MPA106F and MPE106F from TE Connectivity ALCOSWITCH Switches series meet all mandatory criteria and fall within allowable variation parameters.

Parameter Comparison

Engineering Selection Recommendations

Both MPA106F and MPE106F are active production components from TE Connectivity ALCOSWITCH Switches and satisfy all electrical and mechanical substitution requirements for the obsolete MB2011LS1A01-CE.

MPA106F Selection Criteria:

• Meets all mandatory electrical parameters (6A AC at 125V, 4A DC at 28V)
• Active product status ensures long-term availability
• ROHS3 compliant with MSL 1 rating
• Panel cutout diameter 6.35mm requires panel modification of 0.15mm
• Electrical life rating of 50,000 cycles exceeds original specification

MPE106F Selection Criteria:

• Meets all mandatory electrical parameters (6A AC at 125V, 4A DC at 28V)
• Active product status ensures long-term availability
• ROHS3 compliant with MSL 1 rating
• Splash proof ingress protection provides enhanced environmental sealing
• REACH affected status requires compliance verification in regulated markets
• Panel cutout diameter 6.35mm requires panel modification of 0.15mm
• Electrical life rating of 50,000 cycles exceeds original specification

Selection between MPA106F and MPE106F depends on application environmental requirements and regulatory compliance obligations.

Frequently Asked Questions (FAQ)

Q: Can MPA106F or MPE106F directly replace MB2011LS1A01-CE without panel modification?

A: Panel cutout diameter differs by 0.15mm (original 6.50mm versus substitute 6.35mm). Panel mounting holes may require enlargement or reaming to accommodate the substitute parts. Mechanical fit verification is necessary before production implementation.

Q: Are the DC voltage ratings of 28V sufficient for applications designed for 30V?

A: MPA106F and MPE106F are rated for 28V DC, which is 2V below the original MB2011LS1A01-CE specification of 30V DC. Applications operating at or near 30V DC should be evaluated for margin adequacy. For applications operating below 28V DC, substitution is acceptable.

Q: What is the difference between MPA106F and MPE106F?

A: Both parts share identical electrical ratings and core specifications. MPE106F provides splash proof ingress protection, whereas MPA106F does not specify ingress protection. MPE106F carries REACH affected status, requiring compliance verification in applicable jurisdictions. MPA106F REACH status is vendor undefined.

Q: Does the narrower operating temperature range of the substitutes affect compatibility?

A: The original MB2011LS1A01-CE operates from -30°C to 85°C. Both substitutes operate from -20°C to 80°C. Applications requiring operation below -20°C or above 80°C are not compatible with these substitutes. For applications within the -20°C to 80°C range, substitution is acceptable.

Q: Are there packaging differences between the main part and substitutes?

A: MB2011LS1A01-CE is packaged with specific inventory designation. MPA106F and MPE106F are supplied in bulk packaging. Packaging configuration may affect procurement, handling, and storage procedures.

Q: What certifications apply to each part?

A: All three parts are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level). MB2011LS1A01-CE is REACH unaffected. MPA106F REACH status is vendor undefined. MPE106F is REACH affected. Regulatory compliance requirements should be verified based on end-use application and market jurisdiction.
