Key Parameters

Substitute Part Grouping Explanation

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

• Circuit configuration must be DPDT
• Switch function must be On-Momentary
• AC current rating must be 6A minimum
• AC voltage rating must be 125V minimum
• DC voltage rating must be 28V minimum
• Mounting type must be Panel Mount, Rear
• Termination style must be Solder Lug
• Panel cutout diameter must accommodate 6.35mm to 6.50mm range

The identified substitute parts MPA206R and MPE206R meet these electrical and mechanical requirements. Both are manufactured by TE Connectivity ALCOSWITCH Switches and maintain active product status, ensuring long-term availability and supply chain stability.

Parameter Comparison

Engineering Selection Recommendations

Both MPA206R and MPE206R are suitable substitutes for the obsolete MB2061LS1W01-BA based on electrical and mechanical compatibility. The selection between these two active alternatives depends on application environment requirements:

MPA206R is appropriate for standard indoor applications where ingress protection is not a design requirement. This part maintains full electrical compatibility with the original specification.

MPE206R provides enhanced environmental protection through splash-proof ingress rating, making it suitable for applications exposed to moisture or liquid splash conditions. This part offers the same electrical performance as MPA206R with additional environmental durability.

Both substitute parts exceed the original electrical life specification (50,000 cycles versus 25,000 cycles), providing improved reliability margins. Both maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring regulatory and manufacturing process compatibility.

Frequently Asked Questions (FAQ)

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

A: Both parts are electrically and mechanically compatible. The panel cutout diameter difference (6.35mm versus 6.50mm) is within acceptable tolerance for standard panel mount applications. Verify panel hole dimensions in your specific assembly before implementation.

Q: What is the difference between MPA206R and MPE206R?

A: Both parts share identical electrical specifications and operating characteristics. MPE206R includes splash-proof ingress protection, while MPA206R does not. Select MPE206R for applications requiring moisture resistance.

Q: Are there any compliance or certification differences between the substitute parts?

A: All three parts maintain ROHS3 compliance and unlimited moisture sensitivity rating. MPA206R and MPE206R are REACH Affected, while the original MB2061LS1W01-BA is REACH Unaffected. Verify REACH compliance requirements for your specific application and end market.

Q: How do the electrical life ratings compare?

A: The original MB2061LS1W01-BA is rated for 25,000 electrical cycles. Both MPA206R and MPE206R are rated for 50,000 electrical cycles, providing double the operational life expectancy.

Q: What are the operating temperature differences?

A: MB2061LS1W01-BA operates from -30°C to 85°C. MPA206R and MPE206R operate from -20°C to 80°C. Verify that the narrower temperature range of the substitute parts is acceptable for your application environment.

Q: Are the DC current ratings compatible?

A: The original part is rated for 3A DC at 30V. Both substitute parts are rated for 4A DC at 28V. For DC applications at or below 3A and 28V, the substitutes are fully compatible. Applications requiring 3A to 4A DC operation at 28V are within the substitute part capability.
