MB2061LS1W01-CF Equivalent & Substitute Parts

Part Overview

The MB2061LS1W01-CF is a DPDT pushbutton switch manufactured by NKK Switches, rated for 6A at 125V AC and 3A at 30V DC. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing production, maintenance, and design updates. The switch features panel mount rear termination with solder lug connections and operates across -30°C to 85°C with 100,000 mechanical cycles and 25,000 electrical cycles.

Key Parameters

Substitute Part Grouping Explanation

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

Mandatory Matching Parameters:

• Circuit configuration: DPDT
• Switch function: On-Momentary
• AC current rating: 6A minimum
• AC voltage rating: 125V minimum
• Mounting type: Panel Mount, Rear
• Termination style: Solder Lug
• RoHS compliance: ROHS3 Compliant

Allowable Variations:

• DC current rating: Substitute may exceed 3A (higher ratings are acceptable)
• DC voltage rating: Substitute may exceed 30V (higher ratings are acceptable)
• Panel cutout diameter: Minor variations within mechanical tolerance (6.35mm to 6.50mm acceptable for standard panel mount applications)
• Operating temperature range: Substitute may have narrower range if minimum -20°C and maximum 80°C are met
• Electrical life: Substitute may exceed 25,000 cycles (higher ratings acceptable)
• Mechanical life: Substitute may have unspecified rating if electrical performance is verified

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

Parameter Comparison

Engineering Selection Recommendations

Both MPA206R and MPE206R are active production alternatives to the obsolete MB2061LS1W01-CF. Selection between these substitutes is based on application requirements:

MPA206R Selection Criteria:

• Standard environmental conditions without splash or moisture exposure
• Applications requiring baseline DPDT 6A/125V AC performance
• Cost-optimized designs where ingress protection is not required
• ROHS3 compliant for regulated markets

MPE206R Selection Criteria:

• Applications requiring splash-proof ingress protection
• Environments with potential moisture or liquid exposure
• Enhanced reliability requirements in harsh conditions
• ROHS3 compliant for regulated markets

Both substitutes provide superior electrical life (50,000 cycles versus 25,000 cycles) and higher DC current ratings (4A versus 3A) compared to the original part. Panel cutout diameter variation from 6.50mm to 6.35mm requires mechanical verification for existing panel designs.

Frequently Asked Questions (FAQ)

Q: Can MPA206R or MPE206R directly replace MB2061LS1W01-CF in existing designs?

A: Both parts meet the mandatory electrical parameters (DPDT, 6A/125V AC, On-Momentary function, solder lug termination). Panel cutout diameter differs by 0.15mm (6.50mm to 6.35mm), requiring mechanical verification for existing panel cutouts. Operating temperature range is narrower (-20°C to 80°C versus -30°C to 85°C), which must be evaluated against application requirements.

Q: What is the difference between MPA206R and MPE206R?

A: Both parts share identical electrical specifications and operating parameters. The primary distinction is ingress protection: MPE206R provides splash-proof protection, while MPA206R does not specify ingress protection. Selection depends on environmental exposure requirements.

Q: Are the substitute parts RoHS compliant?

A: Yes, both MPA206R and MPE206R are ROHS3 compliant, matching the compliance status of the original MB2061LS1W01-CF.

Q: What is the impact of the narrower operating temperature range in the substitutes?

A: The substitute parts operate from -20°C to 80°C, compared to the original -30°C to 85°C range. Applications requiring operation below -20°C or above 80°C must evaluate alternative solutions or confirm that the narrower range is acceptable for the specific use case.

Q: Do the substitutes have better electrical life ratings?

A: Yes, both MPA206R and MPE206R are rated for 50,000 electrical cycles, compared to 25,000 cycles for the MB2061LS1W01-CF. This represents a 2x improvement in electrical life expectancy.

Q: What packaging is available for the substitute parts?

A: Both MPA206R and MPE206R are supplied in bulk packaging, with 1181 and 1072 units respectively available in current inventory.
