MB2011LS1W01 Equivalent & Substitute Parts

Part Overview

The MB2011LS1W01 is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuitry with a momentary on-function. This component is rated for 6A at 125V AC and 3A at 30V DC, with panel mount rear termination via solder lugs. The product is currently obsolete, necessitating identification of functionally equivalent alternatives for ongoing system support and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MB2011LS1W01 are identified based on the following critical parameters that determine functional equivalence:

• Circuit Configuration: SPDT topology required for identical switching behavior
• Switch Function: Momentary (On-Mom) operation for application compatibility
• Current Rating: Minimum 6A AC capability to meet or exceed original specification
• Voltage Rating: Minimum 125V AC and 28V DC to maintain electrical safety margins
• Mounting Type: Panel mount rear configuration with solder lug termination
• Panel Cutout Diameter: Compatibility within acceptable mechanical tolerance (6.35mm to 6.50mm)
• Regulatory Compliance: ROHS3 compliance required for modern supply chain integration

The identified substitutes are grouped as follows:

NKK Switches Family (MBN15LS1W01): Direct manufacturer alternative within the same product ecosystem, maintaining design continuity.

TE Connectivity ALCOSWITCH Series (MPA106F, MPE106F): Cross-manufacturer alternatives meeting all critical electrical and mechanical parameters with active product status.

Parameter Comparison

Engineering Selection Recommendations

MBN15LS1W01 (NKK Switches): This substitute maintains manufacturer continuity within the NKK Switches product line. As an active product with ROHS3 compliance, it provides direct supply chain support. Selection of this part is appropriate for applications requiring NKK Switches ecosystem integration and long-term availability assurance.

MPA106F (TE Connectivity ALCOSWITCH): This substitute meets all critical electrical parameters (6A AC, 125V AC, 4A DC, 28V DC) and mechanical requirements (panel mount rear, solder lug termination). The part demonstrates superior electrical life (50,000 cycles versus 25,000 cycles) and maintains ROHS3 compliance. The 6.35mm panel cutout diameter requires verification against existing panel drilling specifications. Selection is appropriate for applications where cross-manufacturer sourcing is acceptable and enhanced electrical life is beneficial.

MPE106F (TE Connectivity ALCOSWITCH): This substitute provides identical electrical ratings to MPA106F with the addition of splash proof ingress protection. ROHS3 compliance is confirmed with REACH affected status. The 6.35mm panel cutout diameter requires verification against existing panel drilling specifications. Selection is appropriate for applications requiring enhanced environmental protection and extended electrical life.

Frequently Asked Questions (FAQ)

Q: Can MPA106F and MPE106F be used interchangeably with MB2011LS1W01?

A: Both parts meet the critical electrical parameters (6A AC, 125V AC) and mechanical mounting requirements (panel mount rear, solder lug termination). The primary consideration is panel cutout diameter: the original part specifies 6.50mm, while both TE Connectivity alternatives specify 6.35mm. Mechanical compatibility must be verified for existing panel installations. Both parts are electrically suitable for direct substitution in new designs.

Q: What is the significance of the panel cutout diameter difference?

A: The MB2011LS1W01 requires a 6.50mm circular panel cutout, while MPA106F and MPE106F require 6.35mm. For retrofit applications using existing panels, the 6.35mm diameter may not provide adequate clearance in a 6.50mm hole. New panel designs can accommodate the 6.35mm specification without issue.

Q: How do the electrical life ratings compare?

A: The original MB2011LS1W01 is rated for 25,000 electrical cycles. Both MPA106F and MPE106F are rated for 50,000 electrical cycles, providing double the operational life. This enhanced rating may extend component service intervals in high-cycle applications.

Q: What is the difference between MPA106F and MPE106F?

A: Both parts share identical electrical ratings and mechanical specifications. MPE106F includes splash proof ingress protection, while MPA106F does not specify ingress protection. Selection between these parts depends on environmental exposure requirements. MPE106F is appropriate for applications with moisture or splash exposure.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. MB2011LS1W01, MBN15LS1W01, MPA106F, and MPE106F are all ROHS3 compliant, ensuring compatibility with modern supply chain requirements and environmental regulations.

Q: What is the operating temperature range consideration?

A: The original MB2011LS1W01 operates from -30°C to 85°C. Both TE Connectivity alternatives (MPA106F, MPE106F) operate from -20°C to 80°C. For applications requiring operation below -20°C or above 80°C, the original specification or MBN15LS1W01 should be evaluated if temperature data is available.
