MB2061LS1W01-CG Equivalent & Substitute Parts

Part Overview

The MB2061LS1W01-CG is a DPDT pushbutton switch manufactured by NKK Switches, rated for 6A at 125V AC and 3A at 30V DC. This component features a round blue button actuator with solder lug termination and epoxy sealed terminals, designed for panel mount rear installation. The product is currently obsolete, making equivalent substitute parts necessary for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

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

• Circuit Configuration: Must be DPDT
• Switch Function: Must be On-Momentary
• AC Current Rating: Must support minimum 6A at 125V
• DC Current Rating: Must support minimum 3A at 30V
• Mounting Configuration: Must be Panel Mount, Rear with solder lug termination
• Panel Cutout Compatibility: Circular opening, nominal 6.35mm to 6.50mm diameter range
• Compliance: ROHS3 compliance required

The substitute parts MPA206R and MPE206R meet these core electrical and mechanical requirements. Both are active products from TE Connectivity ALCOSWITCH Switches with DPDT configuration, On-Momentary function, 6A AC rating, and solder lug termination suitable for panel mount rear installation.

Parameter Comparison

Engineering Selection Recommendations

Both MPA206R and MPE206R are suitable substitutes for the obsolete MB2061LS1W01-CG based on electrical and mechanical compatibility. The substitute parts exceed the original specifications in DC current rating (4A versus 3A) and electrical life (50,000 cycles versus 25,000 cycles), providing enhanced performance margins.

MPA206R is the baseline equivalent, meeting all core requirements with active product status and full ROHS3 compliance.

MPE206R provides identical electrical specifications to MPA206R with the addition of splash proof ingress protection, offering enhanced environmental protection for applications requiring moisture resistance.

Both substitutes operate within a narrower temperature range (-20°C to 80°C versus -30°C to 85°C). Panel cutout diameter is 6.35mm versus the original 6.50mm; existing panel openings may require minor mechanical adaptation.

Frequently Asked Questions (FAQ)

Q: Can MPA206R or MPE206R directly replace MB2061LS1W01-CG in existing applications?

A: Both parts are electrically compatible. The DPDT circuit configuration, On-Momentary function, 6A AC rating, and solder lug termination match the original specification. Panel cutout diameter differs by 0.15mm (6.35mm versus 6.50mm), which may require mechanical adjustment to existing panel openings.

Q: What is the difference between MPA206R and MPE206R?

A: Both parts share identical electrical specifications and ratings. MPE206R includes splash proof ingress protection, while MPA206R does not specify ingress protection. Selection depends on environmental exposure requirements.

Q: Are the substitute parts available in the same packaging as the original?

A: The original MB2061LS1W01-CG was packaged individually. Both MPA206R and MPE206R are supplied in bulk packaging. Quantity requirements and packaging consolidation should be evaluated during procurement.

Q: Do the substitute parts meet the same compliance standards?

A: Both MPA206R and MPE206R are ROHS3 compliant, matching the original part. REACH status differs: the original is REACH Unaffected, while substitutes are REACH Affected. Compliance verification for specific end-use applications is required.

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

A: Substitute parts operate from -20°C to 80°C versus the original -30°C to 85°C. Applications requiring operation below -20°C or above 80°C are outside the substitute specification and require alternative solutions.

Q: How do the electrical life ratings compare?

A: The original part is rated for 25,000 electrical cycles. Both substitutes are rated for 50,000 electrical cycles, providing double the operational life expectancy under equivalent switching conditions.
