MB2011LS1A01-CG Equivalent & Substitute Parts

Part Overview

The MB2011LS1A01-CG 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. Substitute parts must maintain electrical performance specifications and mechanical compatibility within the defined parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Circuit type: SPDT configuration required
• Switch function: On-Momentary operation
• AC current rating: Minimum 6A at 125V
• DC current rating: Minimum 3A at 30V
• Mounting configuration: Panel Mount, Rear
• Termination: Solder Lug
• Panel cutout: Circular 6.35mm or 6.50mm diameter (within mechanical tolerance)

Identified Substitutes:

• MPA106F (TE Connectivity ALCOSWITCH Switches)
• MPE106F (TE Connectivity ALCOSWITCH Switches)

Both substitute parts meet the primary electrical criteria. MPA106F and MPE106F provide 6A AC and 4A DC ratings, exceeding the minimum DC requirement of 3A. Both maintain 125V AC and 28V DC voltage ratings, which satisfy the operational envelope. Panel cutout dimensions of 6.35mm are mechanically compatible within standard panel mount tolerances.

Parameter Comparison

Engineering Selection Recommendations

MPA106F Selection Criteria: MPA106F is an active product from TE Connectivity ALCOSWITCH Switches with ROHS3 compliance and unlimited moisture sensitivity rating. This substitute meets all primary electrical specifications and maintains panel mount rear configuration with solder lug termination. Current inventory of 1578 units supports production continuity. Selection is appropriate for applications where ingress protection is not a design requirement.

MPE106F Selection Criteria: MPE106F is an active product from TE Connectivity ALCOSWITCH Switches with ROHS3 compliance, REACH affected status, and unlimited moisture sensitivity rating. This substitute exceeds primary electrical specifications and includes splash proof ingress protection. Current inventory of 1039 units is available. Selection is appropriate for applications requiring enhanced environmental protection or where splash resistance is specified.

Temperature Range Consideration: Both substitutes operate within -20°C to 80°C, which is narrower than the original MB2011LS1A01-CG range of -30°C to 85°C. Applications requiring operation below -20°C or above 80°C require design review.

Frequently Asked Questions (FAQ)

Q: Can MPA106F or MPE106F directly replace MB2011LS1A01-CG in existing designs?

A: Both parts maintain SPDT circuit configuration, On-Momentary function, 6A AC rating at 125V, and solder lug termination. Panel cutout diameter difference (6.35mm vs 6.50mm) is within standard mechanical tolerance for circular panel mount holes. Electrical compatibility is confirmed across all primary parameters.

Q: What is the difference between MPA106F and MPE106F?

A: Both parts share identical electrical specifications (6A AC, 4A DC, 125V AC, 28V DC) and operating temperature range (-20°C to 80°C). The primary distinction is ingress protection: MPE106F provides splash proof protection, while MPA106F does not specify ingress protection. MPE106F carries REACH affected status, while MPA106F status is vendor undefined.

Q: Are there temperature limitations when substituting?

A: Yes. The original MB2011LS1A01-CG operates from -30°C to 85°C. Both substitute parts operate from -20°C to 80°C. Applications requiring operation below -20°C or above 80°C are outside the substitute parts' specified range and require alternative component selection.

Q: What is the DC voltage difference between the original and substitutes?

A: MB2011LS1A01-CG is rated for 30V DC, while MPA106F and MPE106F are rated for 28V DC. Both substitutes are suitable for applications operating at or below 28V DC. Applications requiring operation above 28V DC but within 30V DC require design review.

Q: How do electrical life ratings compare?

A: MB2011LS1A01-CG specifies 25,000 electrical cycles. Both MPA106F and MPE106F specify 50,000 electrical cycles, providing extended operational life in cyclic switching applications.

Q: What packaging is available for substitute parts?

A: Both MPA106F and MPE106F are supplied in bulk packaging. Original inventory quantities are 1578 units (MPA106F) and 1039 units (MPE106F).
