MB2011SS1W01-BH Equivalent & Substitute Parts

Part Overview

The MB2011SS1W01-BH is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with 6A AC / 3A DC current rating and 125V AC / 30V DC voltage rating. 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 epoxy sealed terminals for environmental protection.

Key Parameters

Substitute Part Grouping Explanation

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

Primary Compatibility Criteria:

• Circuit configuration: SPDT
• Switch function: On-Mom (momentary)
• Current rating: Minimum 6A AC
• Voltage rating: Minimum 125V AC
• Mounting type: Panel Mount, Rear
• Termination style: Solder Lug
• Panel cutout diameter: Compatible with 6.50mm specification

Substitute Classification:

MBN15SS1W01-BH (NKK Switches) qualifies as the manufacturer-recommended direct replacement, maintaining identical electrical specifications and mounting characteristics while offering active product status.

MPA106F and MPE106F (TE Connectivity ALCOSWITCH Switches) function as functionally equivalent alternatives. Both parts meet or exceed the primary electrical requirements (6A AC at 125V AC) and share identical mounting and termination configurations. Panel cutout diameter for these alternatives is 6.35mm, representing a minor dimensional variance within acceptable mechanical tolerance for standard panel mount applications.

Engineering Selection Recommendations

Primary Selection: MBN15SS1W01-BH

MBN15SS1W01-BH is the manufacturer-recommended equivalent from NKK Switches. This part maintains active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment. Selection of this part eliminates design re-qualification requirements and maintains consistency within the NKK Switches product ecosystem.

Alternative Selection: MPA106F or MPE106F

Both TE Connectivity ALCOSWITCH parts satisfy the electrical and mechanical requirements of the original specification. MPA106F provides a cost-effective alternative with active inventory status and ROHS3 compliance. MPE106F offers identical electrical performance with the addition of splash-proof ingress protection and REACH compliance documentation, suitable for applications requiring enhanced environmental resistance.

The 0.15mm panel cutout diameter reduction (6.50mm to 6.35mm) represents a negligible mechanical variance for standard panel mount installations and does not constitute a functional limitation.

Frequently Asked Questions (FAQ)

Q: Can MPA106F or MPE106F directly replace MB2011SS1W01-BH without circuit modification?

A: Yes. Both parts maintain identical SPDT circuit configuration, On-Mom switch function, 6A AC / 125V AC electrical ratings, panel mount rear termination, and solder lug connections. No circuit modifications are required.

Q: What is the significance of the panel cutout diameter difference (6.50mm vs. 6.35mm)?

A: The 0.15mm reduction in panel cutout diameter for MPA106F and MPE106F represents standard manufacturing tolerance variation. Existing panel cutouts designed for 6.50mm will accommodate 6.35mm diameter components without functional impact. For new panel designs, either dimension is acceptable.

Q: Are there compliance differences between the substitute parts?

A: All three parts maintain ROHS3 compliance. MPA106F carries undefined REACH status from the vendor. MPE106F is REACH Affected. MB2011SS1W01-BH is REACH Unaffected. Application requirements for REACH compliance should determine part selection if regulatory documentation is critical.

Q: How do the electrical life ratings compare?

A: MB2011SS1W01-BH specifies 25,000 electrical cycles. Both MPA106F and MPE106F specify 50,000 electrical cycles, representing a 2x improvement in rated cycle life. This difference does not affect substitution eligibility but may provide extended service life in high-cycle applications.

Q: What is the operating temperature range difference?

A: MB2011SS1W01-BH operates from -30°C to 85°C. MPA106F and MPE106F operate from -20°C to 80°C. For applications requiring operation below -20°C or above 80°C, the original part specification must be maintained.

Q: Does MPE106F's splash-proof rating provide additional value?

A: MPE106F includes splash-proof ingress protection, while MB2011SS1W01-BH does not specify ingress protection. For applications exposed to moisture or liquid splash, MPE106F provides enhanced environmental protection. For sealed or dry environments, this feature provides no functional advantage.
