MB2065SS1W01-BA Equivalent & Substitute Parts

Part Overview

The MB2065SS1W01-BA is an NKK Switches pushbutton switch with SPDT (Single Pole Double Throw) configuration, rated for 6A at 125V AC and 3A at 30V DC. This component features a round black button actuator with solder lug termination and panel mount rear installation. The product is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new design implementations where this specific model is no longer available from the manufacturer.

Key Parameters

Substitute Part Grouping Explanation

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

• Circuit Configuration: Must be SPDT
• Switch Function: Must be On-On
• Current Rating: Must support minimum 6A AC; DC rating of 3A or higher
• Voltage Rating: Must support minimum 125V AC; DC rating of 28V or higher
• Mounting Type: Must be Panel Mount, Rear
• Termination Style: Must be Solder Lug
• Panel Cutout Compatibility: Circular cutout diameter must accommodate 6.50mm or smaller
• Regulatory Compliance: Must be ROHS3 Compliant

The substitute parts listed below meet these core electrical and mechanical requirements, though individual specifications may vary in secondary parameters such as actuator type, operating temperature range, and electrical life cycles.

Parameter Comparison

Engineering Selection Recommendations

MBN125SS1W01-BA (NKK Switches, Active Status): This is the manufacturer-recommended substitute from NKK Switches. As an active product from the original manufacturer, it provides the most direct replacement path with equivalent electrical specifications and identical mounting configuration. Selection of this part eliminates potential compatibility concerns and maintains supply chain continuity with the original equipment manufacturer.

8161SHZQE1 (C&K, Active Status): This C&K part meets core electrical requirements with 6A AC/DC rating and 120V AC / 28V DC voltage specifications. The 6.35mm panel cutout is compatible with the original 6.50mm requirement. ROHS3 compliance and solder lug termination align with regulatory and assembly requirements. Electrical life of 50,000 cycles exceeds the original specification.

MPA106D (TE Connectivity ALCOSWITCH, Active Status): This TE Connectivity part provides 6A AC and 4A DC current ratings with 125V AC / 28V DC voltage support. The 6.35mm panel cutout accommodates the original mounting requirement. ROHS3 compliance and 50,000-cycle electrical life meet or exceed original specifications. Plunger actuator type differs from the original round button design.

MPE106D (TE Connectivity ALCOSWITCH, Active Status): Electrically equivalent to MPA106D with identical current and voltage ratings. Includes splash-proof ingress protection, providing enhanced environmental resistance beyond the original specification. 6.35mm panel cutout and 50,000-cycle electrical life maintain compatibility and performance standards.

MPG106D (TE Connectivity ALCOSWITCH, Active Status): Meets all core electrical requirements with 6A AC / 4A DC rating and 125V AC / 28V DC voltage support. Features round black button actuator matching the original design. The 11.80mm panel cutout is larger than the original 6.50mm requirement and may require panel modification for installation.

Frequently Asked Questions (FAQ)

Q: Can I use MPG106D as a direct replacement if my panel has a 6.50mm cutout?

A: No. The MPG106D requires an 11.80mm panel cutout diameter, which is significantly larger than the original 6.50mm specification. Panel modification would be necessary for installation. Consider MPA106D, MPE106D, or 8161SHZQE1 for direct cutout compatibility.

Q: What is the difference between MPA106D and MPE106D?

A: Both parts share identical electrical specifications (6A AC, 4A DC, 125V AC, 28V DC) and mechanical mounting requirements. MPE106D includes splash-proof ingress protection, while MPA106D does not specify this feature. Selection depends on environmental exposure requirements.

Q: Is the MBN125SS1W01-BA the only NKK Switches substitute available?

A: Based on the provided data, MBN125SS1W01-BA is the manufacturer-recommended NKK Switches substitute. It is classified as active and carries the manufacturer's direct recommendation for replacing the obsolete MB2065SS1W01-BA.

Q: Do all substitute parts meet the original 125V AC rating?

A: All substitute parts except 8161SHZQE1 are rated for 125V AC. The 8161SHZQE1 is rated for 120V AC, which is 5V lower than the original specification. For applications requiring exactly 125V AC operation, select MBN125SS1W01-BA, MPA106D, MPE106D, or MPG106D.

Q: What is the impact of different electrical life ratings?

A: The original MB2065SS1W01-BA specifies 25,000 electrical cycles. All substitute parts provide 50,000 cycles or higher, representing improved durability and extended service life. This is a beneficial characteristic for replacement applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 compliance certification, meeting regulatory requirements equivalent to the original part.
