MB2011SS1W01-BE Equivalent & Substitute Parts

Part Overview

The MB2011SS1W01-BE is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuitry with a rated capacity of 6A at 125V AC and 3A at 30V DC. This component is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. The switch employs panel mount rear termination with solder lug connections and yellow round button actuation, sealed with epoxy-coated terminals for environmental protection.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2011SS1W01-BE is determined by the following critical parameters: SPDT circuit configuration, On-Momentary switch function, 6A AC current rating at 125V AC, panel mount rear termination with solder lug connections, and circular panel cutout dimensions. Substitute parts must maintain electrical compatibility within the specified voltage and current ratings while preserving mechanical mounting characteristics.

The identified substitutes are grouped as follows:

MFR Recommended Substitute: MBN15SS1W01-BE (NKK Switches) — manufacturer-recommended direct replacement from the same OEM, ensuring design continuity and compatibility with existing assemblies.

Similar Substitutes: MPA106F and MPE106F (TE Connectivity ALCOSWITCH Switches) — functionally equivalent SPDT pushbutton switches meeting the 6A/125V AC electrical specification and panel mount rear configuration, with active product status and current manufacturing availability.

Parameter Comparison

Engineering Selection Recommendations

MBN15SS1W01-BE is the preferred substitute when design continuity with NKK Switches components is required. As an active product from the original manufacturer, this part ensures consistency with existing supply chain relationships and documentation. However, the limited electrical parameter data provided requires confirmation of full compatibility with the original specification before implementation.

MPA106F and MPE106F are functionally equivalent alternatives from TE Connectivity ALCOSWITCH Switches. Both parts maintain ROHS3 compliance and active product status. The TE Connectivity options provide higher electrical life ratings (50,000 cycles versus 25,000 cycles) and superior DC current capacity (4A versus 3A). MPE106F offers additional splash-proof ingress protection, suitable for applications requiring enhanced environmental resistance. The panel cutout diameter difference (6.35mm versus 6.50mm) requires mechanical panel assessment for compatibility.

All substitute candidates maintain ROHS3 compliance and EAR99 export classification, consistent with the original part's regulatory status.

Frequently Asked Questions (FAQ)

Q: Can MBN15SS1W01-BE be used as a direct drop-in replacement for MB2011SS1W01-BE?

A: MBN15SS1W01-BE is the manufacturer-recommended substitute from NKK Switches. However, the mounting type differs (bushing mount versus panel mount rear), requiring mechanical panel redesign. Electrical compatibility is supported by the SPDT configuration and On-Momentary function, but full electrical parameter verification is necessary before implementation.

Q: What are the key differences between MPA106F and MPE106F?

A: Both parts share identical electrical specifications (6A/125V AC, 4A/28V DC, SPDT, On-Momentary). The primary distinction is ingress protection: MPE106F provides splash-proof protection, while MPA106F does not. Selection depends on environmental exposure requirements in the target application.

Q: Are the TE Connectivity substitutes compatible with the original panel cutout?

A: The original MB2011SS1W01-BE specifies a 6.50mm circular panel cutout, while MPA106F and MPE106F require 6.35mm cutouts. This 0.15mm difference may require panel modification or use of adapter bushings. Mechanical fit assessment is necessary before production implementation.

Q: Do the substitute parts meet the original operating temperature range?

A: The original part operates from -30°C to 85°C. MPA106F and MPE106F operate from -20°C to 80°C, representing a narrower range. Applications requiring operation below -20°C or above 80°C require alternative solutions.

Q: What is the electrical life difference between the original and substitute parts?

A: MB2011SS1W01-BE is rated for 25,000 electrical cycles. MPA106F and MPE106F are rated for 50,000 electrical cycles, providing extended service life in high-cycle applications. This represents a performance improvement over the original specification.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. MB2011SS1W01-BE, MPA106F, and MPE106F are all ROHS3 compliant. MBN15SS1W01-BE compliance status is not specified in available data.
