MB2061LS1W01-CC Equivalent & Substitute Parts

Part Overview

The MB2061LS1W01-CC is a pushbutton switch manufactured by NKK Switches with DPDT (Double Pole Double Throw) circuit configuration, rated for 6A at 125V AC and 3A at 30V DC. This component features panel mount rear termination with solder lug connections and a red round button actuator. 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 original manufacturer.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2061LS1W01-CC is determined by the following critical parameters:

Mandatory Matching Parameters:

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

Allowable Variations:

• DC current rating: Substitute must meet or exceed 3A DC
• DC voltage rating: Substitute must meet or exceed 30V DC
• Panel cutout diameter: Tolerance of ±0.15mm acceptable for standard panel mount applications
• Operating temperature range: Substitute may have narrower range if minimum -20°C and maximum 80°C are maintained
• Mechanical and electrical life: Substitute values may differ provided they meet application requirements
• Actuator type and color: May vary based on availability and application needs

The substitute parts MPA206R and MPE206R meet all mandatory matching parameters and fall within allowable variation limits for DC ratings and panel cutout dimensions.

Parameter Comparison

Engineering Selection Recommendations

Both MPA206R and MPE206R are active product alternatives to the obsolete MB2061LS1W01-CC. Selection between these substitutes should be based on the following factors:

MPA206R Selection Criteria:

• Applications requiring standard ingress protection levels
• Designs where splash proof rating is not required
• Cost-sensitive applications where basic environmental protection is sufficient

MPE206R Selection Criteria:

• Applications requiring splash proof ingress protection
• Environments with moisture exposure or washdown conditions
• Designs where enhanced environmental durability is specified

Both substitutes maintain ROHS3 compliance and provide superior electrical life (50,000 cycles versus 25,000 cycles). The panel cutout diameter difference of 0.15mm between the original part (6.50mm) and substitutes (6.35mm) is within standard mechanical tolerance for panel mount applications. DC voltage rating of 28V on both substitutes is acceptable for applications originally specified at 30V DC.

Frequently Asked Questions (FAQ)

Q: Can MPA206R or MPE206R be used as direct replacements for MB2061LS1W01-CC?

A: Yes, both parts meet the mandatory electrical and mechanical parameters. The 0.15mm panel cutout diameter difference is within standard tolerance for panel mount switches. Verify that your application does not require the extended temperature range (-30°C minimum) of the original part, as substitutes operate from -20°C minimum.

Q: What is the difference between MPA206R and MPE206R?

A: Both parts share identical electrical ratings and circuit configuration. The primary difference is ingress protection: MPE206R provides splash proof protection, while MPA206R does not. Select MPE206R for applications exposed to moisture or washdown environments.

Q: Are there any compliance differences between the original part and substitutes?

A: All three parts are ROHS3 compliant. MPA206R and MPE206R are REACH Affected, while the original MB2061LS1W01-CC is REACH Unaffected. Verify REACH compliance requirements for your specific application and end market.

Q: Does the higher electrical life rating of the substitutes affect compatibility?

A: No. The 50,000 cycle electrical life of MPA206R and MPE206R exceeds the original part's 25,000 cycles, providing improved reliability. This represents an enhancement rather than a compatibility concern.

Q: What should be verified before implementing a substitute part?

A: Confirm that your application can accommodate the narrower operating temperature range (-20°C to 80°C versus -30°C to 85°C) and the slightly lower DC voltage rating (28V versus 30V). Verify panel cutout dimensions allow for the 0.15mm diameter reduction. Confirm REACH compliance requirements if applicable to your end market.
