MB2061SS1W01-CF Equivalent & Substitute Parts

Part Overview

The MB2061SS1W01-CF is a DPDT pushbutton switch manufactured by NKK Switches, rated for 6A at 125V AC and 3A at 30V DC. This panel-mount rear component features a round green button actuator with solder lug termination and epoxy sealed terminals. The product is currently obsolete, necessitating identification of functionally equivalent alternatives for ongoing applications and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2061SS1W01-CF is determined by the following critical parameters:

• Circuit configuration must be DPDT
• AC current rating must be 6A minimum
• AC voltage rating must be 125V minimum
• DC voltage rating must be 28V minimum (acceptable tolerance from 30V specification)
• Switch function must be On-Mom
• Mounting type must be Panel Mount, Rear
• Termination style must be Solder Lug
• Panel cutout diameter must accommodate 6.35mm to 6.50mm range
• RoHS3 compliance required

The substitute parts identified meet these core electrical and mechanical parameters. Variations in DC current rating, electrical life cycles, and operating temperature ranges are acceptable within the scope of equivalent functionality for this switch category.

Parameter Comparison

Engineering Selection Recommendations

MPA206R and MPE206R represent the primary equivalents for the MB2061SS1W01-CF. Both are manufactured by TE Connectivity ALCOSWITCH with active product status, ensuring long-term availability and supply chain stability. These parts maintain identical AC electrical ratings (6A at 125V) and equivalent DC ratings (4A at 28V), with panel-mount rear configuration and solder lug termination matching the original specification. Both achieve ROHS3 compliance and provide extended electrical life (50,000 cycles versus 25,000 cycles), offering improved durability.

MPE206R provides additional value through splash-proof ingress protection, suitable for applications requiring environmental resistance beyond the original specification.

MBN25SS1W01-CF, while manufactured by NKK Switches and maintaining active product status, employs bushing mount configuration rather than panel mount rear, limiting its direct substitution applicability to designs permitting mounting type variation.

Frequently Asked Questions (FAQ)

Q: Can MPA206R or MPE206R directly replace MB2061SS1W01-CF in existing designs?

A: Direct replacement is possible for applications where the panel cutout diameter tolerance accommodates 6.35mm (original specification is 6.50mm). The 0.15mm difference is within standard mechanical tolerances for panel-mount switches. Electrical compatibility is confirmed across all critical parameters: DPDT circuit, 6A AC at 125V, 4A DC at 28V, On-Mom function, and solder lug termination.

Q: What is the significance of the extended electrical life in MPA206R and MPE206R?

A: MPA206R and MPE206R provide 50,000 electrical cycles compared to 25,000 cycles in the original MB2061SS1W01-CF. This represents doubled operational life expectancy, reducing maintenance frequency and improving system reliability in high-cycle applications.

Q: Does MPE206R's splash-proof rating affect compatibility?

A: Splash-proof ingress protection in MPE206R is an enhancement that does not compromise compatibility with designs not requiring environmental protection. Applications in sealed or protected enclosures may use either MPA206R or MPE206R interchangeably.

Q: Why is MBN25SS1W01-CF listed as a substitute despite different mounting type?

A: MBN25SS1W01-CF is included as a substitute option for designs where bushing mount configuration is acceptable as an alternative to panel mount rear. This part maintains NKK Switches manufacturing continuity and active product status, suitable for applications permitting mounting type modification.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. MB2061SS1W01-CF, MBN25SS1W01-CF, MPA206R, and MPE206R are all ROHS3 compliant, ensuring regulatory alignment for current and future applications.
