MB2061LS1W01/328 Equivalent & Substitute Parts

Part Overview

The MB2061LS1W01/328 is a DPDT pushbutton switch manufactured by NKK Switches, designed for panel mount rear installation with 6A AC and 3A DC current ratings at 125V AC and 30V DC respectively. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations. Substitute parts must maintain electrical performance across AC/DC ratings, mechanical interface compatibility, and circuit configuration to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2061LS1W01/328 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
• Actuator type: Plunger for Cap
• Termination style: Solder Lug
• RoHS compliance: ROHS3

Allowable Variations:

• DC current rating: Substitute must meet or exceed 3A
• DC voltage rating: Substitute must meet or exceed 30V
• Panel cutout diameter: Tolerance of ±0.15mm acceptable for panel mount compatibility
• Operating temperature range: Substitute may have narrower range if minimum -20°C and maximum 80°C are met
• Electrical life: Substitute may exceed specified cycles

The substitute parts MPA206R and MPE206R satisfy all mandatory parameters while meeting or exceeding the allowable variation thresholds.

Parameter Comparison

Engineering Selection Recommendations

Both MPA206R and MPE206R are active production alternatives to the obsolete MB2061LS1W01/328. Selection between these substitutes is based on application-specific requirements:

MPA206R Selection Criteria:

• Applications requiring standard environmental protection without splash resistance
• Systems where REACH compliance documentation is required
• Designs tolerant of the 6.35mm panel cutout diameter (0.15mm reduction from original)
• Operating environments within -20°C to 80°C range

MPE206R Selection Criteria:

• Applications requiring splash-proof ingress protection
• Outdoor or high-humidity environments
• Systems where REACH compliance documentation is required
• Operating environments within -20°C to 80°C range

Both substitutes provide superior electrical life (50,000 cycles versus 25,000 cycles) and higher DC current rating (4A versus 3A), representing performance improvements over the original component. Panel cutout diameter reduction of 0.15mm requires panel modification or use of adapter hardware for direct mechanical fit.

Frequently Asked Questions (FAQ)

Q: Can MPA206R or MPE206R directly replace MB2061LS1W01/328 without panel modification?

A: Electrical and functional compatibility is confirmed. Mechanical compatibility requires consideration of the panel cutout diameter reduction from 6.50mm to 6.35mm. Direct installation may require panel drilling adjustment or mechanical adapter hardware.

Q: What is the primary difference between MPA206R and MPE206R?

A: Both parts are electrically and functionally identical. MPE206R includes splash-proof ingress protection, while MPA206R does not specify ingress protection. Selection depends on environmental exposure requirements.

Q: Are the substitute parts suitable for DC applications?

A: Yes. Both MPA206R and MPE206R are rated for 4A DC at 28V, exceeding the original 3A DC at 30V specification. DC applications are fully supported.

Q: What compliance certifications apply to the substitute parts?

A: Both MPA206R and MPE206R are ROHS3 compliant and REACH affected. The original MB2061LS1W01/328 is ROHS3 compliant and REACH unaffected. Regulatory documentation requirements should be confirmed for your application.

Q: Do the substitute parts have longer operational life?

A: Yes. Both substitutes provide 50,000 electrical cycles compared to 25,000 cycles for the original part, representing a 100% improvement in electrical life rating.

Q: What is the operating temperature range for the substitute parts?

A: Both MPA206R and MPE206R operate from -20°C to 80°C. The original part operates from -30°C to 85°C. Applications requiring operation below -20°C or above 80°C are not suitable for these substitutes.
