MB2011SS4W01 Equivalent & Substitute Parts

Part Overview

The MB2011SS4W01 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 designed for panel mount, rear installation with solder lug termination and epoxy sealed terminals. The product is currently obsolete, making identification of equivalent and substitute parts essential for ongoing system maintenance and new design implementations where this functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2011SS4W01 is determined by the following critical parameters:

Primary Compatibility Criteria:

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

Substitute Parts Identified:

MBN15SS4W01 (NKK Switches) — Manufacturer-recommended substitute. Maintains NKK Switches product line continuity with active product status. Specifications align with core electrical and mechanical requirements.

MPA106F (TE Connectivity ALCOSWITCH Switches) — Cross-manufacturer equivalent. Matches SPDT circuit, On-Momentary function, 6A AC / 4A DC current rating, 125V AC voltage rating, panel mount rear configuration, and solder lug termination. Panel cutout diameter of 6.35mm provides mechanical compatibility within standard tolerance ranges.

MPE106F (TE Connectivity ALCOSWITCH Switches) — Cross-manufacturer equivalent with enhanced ingress protection (Splash Proof). Electrical and mechanical specifications identical to MPA106F. Suitable for applications requiring additional environmental protection.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Manufacturer Line): MBN15SS4W01 is the manufacturer-recommended substitute from NKK Switches. This part maintains product line continuity and active product status, ensuring long-term availability and supply chain stability. ROHS3 compliance is maintained.

For Cross-Manufacturer Substitution: MPA106F and MPE106F from TE Connectivity ALCOSWITCH Switches provide functionally equivalent alternatives with active product status. Both parts exceed the original electrical life specification (50,000 cycles versus 25,000 cycles) and maintain ROHS3 compliance. The DC current rating is increased to 4A, providing additional operational margin.

For Enhanced Environmental Protection: MPE106F includes Splash Proof ingress protection, suitable for applications requiring protection against moisture ingress. This specification is not present in the original MB2011SS4W01 or MPA106F.

Compliance Considerations: All substitute parts maintain ROHS3 compliance. MPA106F lists REACH status as Vendor Undefined, while MPE106F indicates REACH Affected status. MBN15SS4W01 compliance details are not fully specified in available data.

Frequently Asked Questions (FAQ)

Q: Can MBN15SS4W01 be used as a direct replacement for MB2011SS4W01? A: MBN15SS4W01 is the manufacturer-recommended substitute. However, the mounting type differs (Bushing Mount versus Panel Mount, Rear). Mechanical integration must be verified for your specific application before implementation.

Q: What is the difference between MPA106F and MPE106F? A: Both parts share identical electrical specifications (SPDT, 6A AC, 125V AC, On-Momentary function). MPE106F includes Splash Proof ingress protection, making it suitable for applications with moisture exposure. MPA106F does not specify ingress protection.

Q: Are the panel cutout dimensions compatible between MB2011SS4W01 and the TE Connectivity substitutes? A: MB2011SS4W01 specifies a 6.50mm circular cutout, while MPA106F and MPE106F specify 6.35mm. This 0.15mm difference falls within standard mechanical tolerance ranges for panel mount applications, but physical verification is recommended for precision installations.

Q: Do the substitute parts meet the same temperature operating range? A: MB2011SS4W01 operates from -30°C to 85°C. MPA106F and MPE106F operate from -20°C to 80°C. The substitute parts have a narrower temperature range. Applications requiring operation below -20°C or above 80°C must use the original MB2011SS4W01 or verify alternative solutions.

Q: What is the electrical life advantage of the substitute parts? A: MB2011SS4W01 is rated for 25,000 electrical cycles. MPA106F and MPE106F are rated for 50,000 electrical cycles, providing double the operational life expectancy under electrical switching conditions.

Q: Are all substitute parts RoHS3 compliant? A: Yes. MB2011SS4W01, MBN15SS4W01, MPA106F, and MPE106F all carry ROHS3 Compliant certification.

Q: Which substitute part should be selected for new designs? A: For new designs, MPA106F or MPE106F are recommended due to active product status and extended electrical life. MPE106F is preferred for applications with moisture exposure. Verify panel cutout compatibility and operating temperature requirements for your specific application.
