MB2011SS1W01-BC Equivalent & Substitute Parts

Part Overview

The MB2011SS1W01-BC 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 functionally equivalent alternatives for ongoing design requirements and procurement needs. The switch employs a standard panel mount configuration with rear termination and solder lug connections, suitable for applications requiring momentary on-off switching functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2011SS1W01-BC is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration: SPDT
• Switch function: On-Mom (momentary operation)
• AC current rating: minimum 6A
• AC voltage rating: minimum 125V
• Mounting type: Panel Mount, Rear
• Termination style: Solder Lug
• Panel cutout diameter: compatible with 6.50mm specification

Secondary Compatibility Considerations:

• DC current and voltage ratings may vary within acceptable operational margins
• Operating temperature range may differ provided minimum specifications are met
• Electrical and mechanical life ratings may exceed the original specification
• RoHS and regulatory compliance status

The substitute parts identified—MBN15SS1W01-BC, MPA106F, and MPE106F—satisfy the primary compatibility criteria while maintaining functional equivalence for SPDT momentary switching applications at 6A/125V AC ratings.

Parameter Comparison

Engineering Selection Recommendations

MBN15SS1W01-BC (NKK Switches): This part maintains manufacturer continuity within the NKK Switches product line and is currently in active production status. It is ROHS3 compliant and represents the preferred substitution path for applications requiring direct manufacturer alignment. Detailed electrical specifications are not fully documented in available data; confirmation of SPDT circuit configuration and current ratings is required prior to final selection.

MPA106F (TE Connectivity ALCOSWITCH): This substitute provides equivalent SPDT momentary switching functionality with 6A/125V AC ratings. The part exceeds the original electrical life specification at 50,000 cycles versus 25,000 cycles. DC current rating is increased to 4A, and DC voltage rating is reduced to 28V. Panel cutout diameter is 6.35mm, requiring minor mechanical accommodation. ROHS3 compliance and active product status support long-term availability.

MPE106F (TE Connectivity ALCOSWITCH): This substitute offers identical electrical ratings to MPA106F with the addition of splash-proof ingress protection. Electrical life specification is 50,000 cycles. DC voltage rating is 28V. Panel cutout diameter is 6.35mm. REACH compliance status is documented as affected. ROHS3 compliance and active product status ensure regulatory alignment and procurement continuity.

All three substitute parts satisfy the core functional requirements of SPDT momentary switching at 6A/125V AC with solder lug termination and panel mount rear configuration.

Frequently Asked Questions (FAQ)

Q: Can MPA106F or MPE106F be used as direct replacements for MB2011SS1W01-BC?

A: Both TE Connectivity parts satisfy the primary electrical and mechanical compatibility criteria: SPDT circuit, 6A/125V AC rating, momentary operation, solder lug termination, and panel mount rear configuration. The panel cutout diameter differs slightly (6.35mm versus 6.50mm), which may require minor mechanical adjustment depending on panel design tolerances. DC voltage rating is reduced from 30V to 28V; applications operating above 28V DC require evaluation against actual circuit requirements.

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

A: The MB2011SS1W01-BC specifies a 6.50mm circular cutout, while MPA106F and MPE106F require 6.35mm. This 0.15mm difference is within typical panel fabrication tolerances for most applications. Existing panel cutouts designed for 6.50mm will accommodate 6.35mm diameter bushings with minimal clearance. New panel designs should specify 6.35mm to match the substitute part specifications.

Q: How do the electrical life ratings compare?

A: The original MB2011SS1W01-BC is rated for 25,000 electrical cycles. Both MPA106F and MPE106F are rated for 50,000 electrical cycles, representing a 2x improvement in cycle life. This enhanced specification provides additional margin for applications with extended operational demands.

Q: What is the difference between MPA106F and MPE106F?

A: Both parts share identical electrical specifications: SPDT, 6A/125V AC, 4A/28V DC, 50,000 cycle electrical life, and -20°C to 80°C operating range. The primary distinction is that MPE106F includes splash-proof ingress protection, making it suitable for applications with moisture or liquid exposure. MPA106F lacks specified ingress protection and is suitable for standard dry environments. MPE106F REACH compliance status is documented as affected, while MPA106F status is vendor undefined.

Q: Is MBN15SS1W01-BC recommended over the TE Connectivity alternatives?

A: MBN15SS1W01-BC maintains NKK Switches manufacturer continuity and is the preferred option if detailed electrical specifications can be confirmed to match the original part. However, complete technical data for this part is not fully documented. MPA106F and MPE106F provide fully specified alternatives with documented electrical ratings and active product status, making them suitable selections when manufacturer continuity is not a requirement.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. MB2011SS1W01-BC, MBN15SS1W01-BC, MPA106F, and MPE106F are all ROHS3 compliant, ensuring regulatory alignment for applications subject to RoHS requirements.
