Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2065SS1W01/U is determined by the following critical parameters:

Mandatory Matching Parameters:

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

Allowable Variations:

• DC current rating may exceed 3A (higher ratings are acceptable)
• DC voltage rating may exceed 30V (higher ratings are acceptable)
• Panel cutout diameter: 6.35mm is acceptable (0.15mm difference within mechanical tolerance)
• Operating temperature range may be narrower than -30°C to 85°C
• Electrical life may exceed 25,000 cycles (higher ratings are acceptable)
• Compliance certifications (RoHS, REACH) must meet or exceed original specifications

The substitute parts MB2065SS1W01/CUL-N986, MPA106D, and MPE106D meet these criteria and are qualified as direct replacements.

Engineering Selection Recommendations

MB2065SS1W01/CUL-N986 (NKK Switches - Active) This part maintains the same manufacturer lineage as the original MB2065SS1W01/U and is the direct successor within the NKK Switches product family. It is ROHS3 compliant and represents the primary replacement path for obsolete inventory. Selection of this part ensures continuity with the original design intent and manufacturer support.

MPA106D (TE Connectivity ALCOSWITCH - Active) This part meets all mandatory electrical and mechanical parameters with equivalent AC ratings and improved DC current capability (4A vs. 3A). It provides 50,000 electrical life cycles, doubling the original specification. ROHS3 compliance is maintained. This option is suitable for applications requiring higher DC current capacity or extended operational life.

MPE106D (TE Connectivity ALCOSWITCH - Active) This part matches MPA106D specifications with the addition of splash-proof ingress protection. It is ROHS3 compliant and provides the same electrical performance improvements. Selection of this part is appropriate for applications requiring environmental protection beyond standard panel mount conditions.

All three substitute parts are currently in active production status, ensuring long-term availability and supply chain stability compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can MB2065SS1W01/CUL-N986 be used as a direct replacement for MB2065SS1W01/U? A: Yes. Both parts are from NKK Switches, share identical SPDT circuit configuration, On-On function, 6A AC rating at 125V, plunger actuator, and solder lug termination. The CUL-N986 variant is the active production equivalent.

Q: What is the difference between MPA106D and MPE106D? A: Both parts are electrically and mechanically identical with 6A AC at 125V, 4A DC at 28V, and 50,000 electrical life cycles. The primary difference is that MPE106D includes splash-proof ingress protection, making it suitable for applications with moisture exposure.
