MB2065SS1W01-BC Equivalent & Substitute Parts

Part Overview

The MB2065SS1W01-BC is an NKK Switches pushbutton switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 6A at 125V AC and 3A at 30V DC. This component features a round red button actuator with solder lug termination and panel mount rear installation. The product is currently obsolete, making equivalent and substitute parts necessary for ongoing maintenance, repair, and new design implementations where this functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2065SS1W01-BC is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration: SPDT
• Switch function: On-On
• Current rating: Minimum 6A AC
• Voltage rating: Minimum 125V AC
• Mounting type: Panel Mount, Rear
• Termination style: Solder Lug
• Panel cutout diameter: 6.35mm to 6.50mm (within mechanical tolerance)

Secondary Considerations:

• RoHS3 compliance
• Operating temperature range overlap
• Electrical life rating
• Actuator type compatibility

The substitute parts listed meet these core electrical and mechanical requirements, enabling direct functional replacement in applications designed for the MB2065SS1W01-BC.

Parameter Comparison

Engineering Selection Recommendations

MBN125SS1W01-BC (NKK Switches): This part is the manufacturer-recommended equivalent from NKK Switches. As an active product with ROHS3 compliance and identical voltage ratings (125V AC), it provides the most direct replacement path for the obsolete MB2065SS1W01-BC. Detailed electrical specifications for DC ratings and panel cutout dimensions are not provided in available data.

8161SHZQE1 (C&K): This C&K part meets core electrical requirements with 6A AC at 120V and SPDT On-On configuration. The 6.35mm panel cutout requires verification for mechanical fit in existing installations designed for the 6.50mm cutout of the original part. Operating temperature range is reduced to -30°C to 65°C. REACH status is affected, requiring compliance verification for regulated applications.

MPA106D (TE Connectivity ALCOSWITCH): This part provides 6A AC at 125V with enhanced DC rating of 4A at 28V. Panel cutout is 6.35mm. Operating temperature range is -20°C to 80°C. REACH status is affected. Electrical life is rated at 50,000 cycles, exceeding the original specification.

MPE106D (TE Connectivity ALCOSWITCH): This part matches MPA106D electrical specifications with identical 6A AC at 125V and 4A DC at 28V ratings. Additional ingress protection (Splash Proof) provides enhanced environmental sealing. Panel cutout is 6.35mm. Operating temperature range is -20°C to 80°C. REACH status is affected. Electrical life is 50,000 cycles.

All substitute parts maintain ROHS3 compliance and SPDT On-On functionality. Selection should account for panel cutout diameter tolerance, operating temperature requirements, and regulatory compliance needs specific to the application.

Frequently Asked Questions (FAQ)

Q: Can the MB2065SS1W01-BC be directly replaced with any of these substitute parts?

A: Direct replacement depends on mechanical and electrical compatibility. All listed substitutes meet the core SPDT On-On circuit requirement and 6A AC at 125V electrical specification. However, panel cutout diameter differences (6.50mm original versus 6.35mm substitutes) must be evaluated for mechanical fit. Verify operating temperature range and DC voltage requirements for your specific application.

Q: What is the primary difference between MPA106D and MPE106D?

A: Both parts share identical electrical specifications: 6A AC at 125V, 4A DC at 28V, and SPDT On-On configuration. The key difference is that MPE106D includes Splash Proof ingress protection, while MPA106D does not specify ingress protection. Select MPE106D for applications requiring environmental sealing.

Q: Why is the panel cutout diameter important for substitution?

A: The original MB2065SS1W01-BC requires a 6.50mm circular panel cutout. Most substitute parts (8161SHZQE1, MPA106D, MPE106D) use 6.35mm cutouts. If the panel is already drilled for 6.50mm, mechanical fit may be compromised with 6.35mm parts. Panel modification or selection of MBN125SS1W01-BC (which does not specify cutout diameter) may be necessary.

Q: Are there compliance considerations when selecting a substitute?

A: All listed parts are ROHS3 compliant. However, 8161SHZQE1, MPA106D, and MPE106D have REACH Affected status, while the original MB2065SS1W01-BC and MBN125SS1W01-BC are REACH Unaffected. Verify REACH compliance requirements for your application and regulatory jurisdiction before final selection.

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

A: The MB2065SS1W01-BC is rated for 25,000 electrical cycles. Substitute parts 8161SHZQE1, MPA106D, and MPE106D are rated for 50,000 cycles, providing extended operational life. This represents an improvement over the original specification.

Q: How do operating temperature ranges compare?

A: The original part operates from -30°C to 85°C. The 8161SHZQE1 operates from -30°C to 65°C (reduced upper limit). MPA106D and MPE106D operate from -20°C to 80°C (reduced lower limit). Verify that the substitute's temperature range encompasses your application's operating environment.
