MB2065SS1W01-CF Equivalent & Substitute Parts

Part Overview

The MB2065SS1W01-CF is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) configuration with 6A AC / 3A DC current rating at 125V AC / 30V DC. This component is panel-mounted with rear termination using solder lugs and includes epoxy sealed terminals for environmental protection. The product is currently obsolete, making equivalent substitutes necessary for ongoing maintenance, repair, and new design implementations where this switch type is required.

Key Parameters

Substitute Part Grouping Explanation

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

Primary Matching Criteria:

• Circuit configuration: SPDT
• Switch function: On-On
• AC current rating: 6A minimum
• AC voltage rating: 125V minimum
• Mounting type: Panel Mount, Rear
• Termination style: Solder Lug

Secondary Compatibility Factors:

• Panel cutout diameter tolerance (6.35mm to 6.50mm acceptable for standard panel mount applications)
• DC voltage rating: 28V or higher acceptable (original 30V DC)
• DC current rating: 3A or higher acceptable
• Operating temperature range: -20°C to 80°C acceptable for most industrial applications
• RoHS3 compliance required for regulatory alignment

Identified Substitutes:

1. MBN125SS1W01-CF (NKK Switches) – Manufacturer-recommended direct substitute with bushing mount miniature pushbutton configuration
2. MPA106D (TE Connectivity ALCOSWITCH) – Functionally equivalent SPDT switch meeting all primary electrical parameters
3. MPE106D (TE Connectivity ALCOSWITCH) – Functionally equivalent SPDT switch with enhanced splash-proof ingress protection

Parameter Comparison

Engineering Selection Recommendations

MBN125SS1W01-CF is the manufacturer-recommended substitute from NKK Switches. This option provides continuity with the original equipment manufacturer and maintains design consistency within the NKK Switches product family. Active product status ensures ongoing availability and support.

MPA106D and MPE106D from TE Connectivity ALCOSWITCH represent cross-manufacturer alternatives that meet all primary electrical specifications. Both parts exceed the original electrical life rating (50,000 cycles versus 25,000 cycles) and provide enhanced DC current capability (4A versus 3A). MPE106D includes splash-proof ingress protection, offering additional environmental resilience compared to the original specification.

All three substitutes maintain ROHS3 compliance and are currently in active production status, ensuring long-term component availability. Selection between these options depends on specific application requirements regarding ingress protection, mechanical life requirements, and panel cutout diameter accommodation.

Frequently Asked Questions (FAQ)

Q: Can MPA106D or MPE106D be used as direct replacements for MB2065SS1W01-CF?

A: Yes, both TE Connectivity parts meet the critical electrical parameters: SPDT configuration, 6A AC / 4A DC current rating, 125V AC / 28V DC voltage rating, panel mount rear termination with solder lugs, and On-On switch function. Panel cutout diameter differs slightly (6.35mm versus 6.50mm), which is acceptable within standard panel mount tolerances.

Q: What is the difference between MPA106D and MPE106D?

A: Both parts share identical electrical specifications and mounting characteristics. The primary distinction is ingress protection: MPE106D provides splash-proof protection, while MPA106D offers standard protection. Selection depends on environmental exposure requirements in the target application.

Q: Why does MBN125SS1W01-CF show different mounting type (bushing mount) compared to the original?

A: MBN125SS1W01-CF is classified as a bushing mount miniature pushbutton, which differs from the original panel mount rear configuration. Verify mechanical compatibility with your specific panel mounting requirements before selection.

Q: Are there electrical compatibility concerns with the lower DC voltage rating (28V) in the TE Connectivity substitutes?

A: No. The original MB2065SS1W01-CF is rated for 30V DC, while MPA106D and MPE106D are rated for 28V DC. For applications operating at or below 28V DC, these substitutes are fully compatible. Applications requiring operation above 28V DC should retain the original part or confirm voltage requirements.

Q: What is the impact of the reduced operating temperature range in the TE Connectivity substitutes?

A: The original part operates from -30°C to 85°C, while MPA106D and MPE106D operate from -20°C to 80°C. For applications requiring operation below -20°C or above 80°C, the original part or MBN125SS1W01-CF should be evaluated. Most industrial applications operate within the -20°C to 80°C range.

Q: Do all substitutes maintain RoHS3 compliance?

A: Yes. MB2065SS1W01-CF, MPA106D, and MPE106D are all ROHS3 compliant. MBN125SS1W01-CF compliance status is not specified in available documentation.
