MB2011LS1W01-BA Equivalent & Substitute Parts

Part Overview

The MB2011LS1W01-BA is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with 6A AC / 3A DC current rating at 125V AC / 30V DC. 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 panel mount, rear configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

Mandatory Matching Criteria:

• Circuit configuration: SPDT
• Switch function: On-Momentary
• 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 may exceed 3A specification
• DC voltage rating: Substitute may exceed 30V specification
• Panel cutout diameter: Tolerance within mechanical design constraints (6.35mm to 6.50mm acceptable)
• Operating temperature range: Substitute may have narrower range if minimum -20°C and maximum 80°C are met
• Electrical life: Substitute may exceed 25,000 cycles
• Actuator type: Plunger for cap acceptable as functional equivalent to round button

Identified Substitutes:

• MBN15LS1W01-BA (NKK Switches) — Manufacturer recommended equivalent
• MPA106F (TE Connectivity ALCOSWITCH) — Similar electrical and mechanical specifications
• MPE106F (TE Connectivity ALCOSWITCH) — Similar electrical and mechanical specifications with enhanced ingress protection

Parameter Comparison

Engineering Selection Recommendations

MBN15LS1W01-BA is the primary substitute, being the manufacturer-recommended equivalent from NKK Switches with active product status and ROHS3 compliance. This selection maintains supply chain continuity within the original manufacturer ecosystem.

MPA106F and MPE106F are qualified alternatives from TE Connectivity ALCOSWITCH Switches. Both parts meet the mandatory electrical specifications (6A AC at 125V, SPDT, On-Momentary function) and maintain solder lug termination with panel mount, rear configuration. Both achieve ROHS3 compliance and active product status. MPE106F provides additional splash proof ingress protection, suitable for applications requiring enhanced environmental resistance. The 6.35mm panel cutout diameter requires verification against existing panel tooling designed for 6.50mm diameter.

All three substitutes exceed the original 25,000-cycle electrical life specification with 50,000-cycle ratings, providing improved reliability margins. DC current ratings of 4A on TE Connectivity parts exceed the original 3A specification. Operating temperature ranges on TE Connectivity parts (-20°C to 80°C) are narrower than the original (-30°C to 85°C) and require validation for applications operating at temperature extremes.

Frequently Asked Questions (FAQ)

Q: Can MPA106F or MPE106F be used as direct drop-in replacements for MB2011LS1W01-BA?

A: Electrical compatibility is confirmed. Mechanical compatibility requires panel cutout verification. The substitute parts specify 6.35mm diameter cutout versus the original 6.50mm. Existing panel tooling designed for 6.50mm diameter may require modification or reaming to accommodate the 6.35mm diameter of substitute parts.

Q: What is the difference between MPA106F and MPE106F?

A: Both parts share identical electrical specifications (6A AC at 125V, SPDT, On-Momentary). MPE106F includes splash proof ingress protection, while MPA106F does not specify ingress protection. Selection between these parts depends on environmental exposure requirements in the application.

Q: Are there temperature range limitations when substituting with TE Connectivity parts?

A: TE Connectivity parts (MPA106F and MPE106F) operate from -20°C to 80°C, compared to the original -30°C to 85°C range. Applications requiring operation below -20°C or above 80°C must use MBN15LS1W01-BA or verify that the narrower temperature range is acceptable for the specific application environment.

Q: Do all substitute parts meet RoHS compliance requirements?

A: Yes. MBN15LS1W01-BA, MPA106F, and MPE106F are all ROHS3 compliant, matching the original part specification.

Q: What is the mechanical life expectancy of substitute parts?

A: Mechanical life data is not provided for MBN15LS1W01-BA. TE Connectivity parts (MPA106F and MPE106F) do not specify mechanical life ratings. The original MB2011LS1W01-BA specifies 100,000 mechanical cycles. Mechanical life data should be requested from manufacturers if this parameter is critical for application requirements.
