MB2011LS1W01-BF Equivalent & Substitute Parts

Part Overview

The MB2011LS1W01-BF 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 a panel-mount rear configuration and green round button actuator. The product is currently obsolete, necessitating identification of functionally equivalent alternatives for ongoing applications and new designs.

Key Parameters

Substitute Part Grouping Explanation

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

Primary Matching Criteria:

• Circuit configuration: SPDT
• Switch function: Momentary (On-Mom)
• AC current rating: 6A minimum
• AC voltage rating: 125V minimum
• Mounting configuration: Panel Mount, Rear
• Termination style: Solder Lug
• RoHS compliance: ROHS3 Compliant

Acceptable Variations:

• DC current rating may differ (substitute parts rated 4A DC vs. original 3A DC)
• DC voltage rating may differ (substitute parts rated 28V DC vs. original 30V DC)
• Panel cutout diameter: 6.35mm (substitute) vs. 6.50mm (original) — minor mechanical tolerance
• Operating temperature range may be narrower
• Electrical life rating may exceed original specification

The substitute parts MPA106F and MPE106F from TE Connectivity ALCOSWITCH Switches meet all primary matching criteria. MBN15LS1W01-BF from NKK Switches is listed as the manufacturer-recommended replacement.

Parameter Comparison

Engineering Selection Recommendations

MBN15LS1W01-BF (NKK Switches — Manufacturer Recommended)

This part is designated as the manufacturer-recommended replacement and maintains NKK Switches brand continuity. However, detailed electrical specifications are not provided in available documentation. Verification of mounting configuration compatibility is required, as this part is described as bushing mount rather than panel mount rear, which may necessitate mechanical redesign.

MPA106F (TE Connectivity ALCOSWITCH Switches)

This substitute meets all primary electrical specifications: 6A AC at 125V, SPDT momentary function, panel mount rear configuration, and solder lug termination. The 4A DC rating exceeds the original 3A requirement. The 28V DC rating is marginally lower than the original 30V but remains suitable for most DC applications. Operating temperature range is narrower (-20°C to 80°C vs. -30°C to 85°C). Electrical life of 50,000 cycles doubles the original specification. ROHS3 compliance is confirmed. Panel cutout diameter of 6.35mm is 0.15mm smaller than the original 6.50mm, requiring verification of mechanical fit in existing panel designs.

MPE106F (TE Connectivity ALCOSWITCH Switches)

This substitute provides identical electrical specifications to MPA106F with the addition of splash-proof ingress protection. All electrical parameters, mounting configuration, and termination style match the selection criteria. REACH compliance status is documented as affected, whereas the original part is REACH unaffected. This designation may require compliance verification for specific applications or markets.

Frequently Asked Questions (FAQ)

Q: Can MPA106F or MPE106F be used as direct replacements for MB2011LS1W01-BF?

A: Both parts meet the critical electrical specifications: 6A AC at 125V, SPDT momentary function, panel mount rear configuration, and solder lug termination. The primary consideration is mechanical fit. The panel cutout diameter is 6.35mm (substitute) versus 6.50mm (original), a 0.15mm difference. Existing panel cutouts designed for 6.50mm may require enlargement or use of adapter bushings. Verify mechanical compatibility before implementation.

Q: What is the significance of the 4A DC rating on substitute parts versus the 3A DC rating on the original?

A: The substitute parts (MPA106F, MPE106F) are rated for 4A DC, exceeding the original 3A DC specification. This represents a performance improvement and does not create compatibility issues. Applications operating at or below 3A DC will function within the substitute part's rated capacity with additional margin.

Q: How does the 28V DC rating on substitute parts compare to the original 30V DC rating?

A: The substitute parts are rated for 28V DC, which is 2V lower than the original 30V DC specification. For applications operating at or below 28V DC, the substitute parts are fully compatible. Applications requiring operation above 28V DC but at or below 30V DC should be evaluated for risk tolerance, as the substitute parts operate outside their rated specification in this voltage window.

Q: What is the difference between MPA106F and MPE106F?

A: Both parts share identical electrical specifications and mounting configurations. The primary difference is ingress protection: MPE106F includes splash-proof protection, while MPA106F does not specify ingress protection. Additionally, MPE106F has REACH compliance status documented as affected, whereas MPA106F status is vendor undefined. Select MPE106F for applications requiring splash or moisture resistance.

Q: Is MBN15LS1W01-BF a suitable replacement?

A: MBN15LS1W01-BF is designated as the manufacturer-recommended replacement from NKK Switches. However, it is described as a bushing mount miniature pushbutton, whereas the original is panel mount rear. This mounting configuration difference may require mechanical redesign. Detailed electrical specifications for this part are not provided. Consult NKK Switches technical documentation to confirm compatibility with your specific application requirements.

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

A: Substitute parts (MPA106F, MPE106F) operate from -20°C to 80°C, compared to the original -30°C to 85°C range. Applications operating within the -20°C to 80°C window are fully compatible. Applications requiring operation below -20°C or above 80°C should not use these substitute parts.

Q: Do substitute parts maintain RoHS3 compliance?

A: Yes, both MPA106F and MPE106F are ROHS3 compliant, matching the original part's compliance status. This ensures compatibility with RoHS-regulated markets and applications.
