MB2061LD3W01 Equivalent & Substitute Parts

Part Overview

The MB2061LD3W01 is a DPDT pushbutton switch manufactured by NKK Switches, rated for 6A at 125V AC and 3A at 30V DC. This component features panel mount rear termination with solder lug connections and IP67 ingress protection. The product is currently obsolete, making equivalent substitute parts necessary for ongoing maintenance, repair, and legacy system support applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2061LD3W01 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
• 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 rear panel mount applications)
• Operating temperature range: Substitute may have narrower range if it encompasses the application's operating conditions
• Electrical life: Substitute may exceed 25,000 cycles (higher cycle ratings are acceptable)
• Ingress protection: Substitute may exceed IP67 (higher ratings are acceptable)

The substitute parts MPA206R and MPE206R meet these criteria as active, ROHS3-compliant DPDT pushbutton switches with matching AC ratings and panel mount rear termination.

Parameter Comparison

Engineering Selection Recommendations

Both MPA206R and MPE206R are suitable substitutes for the obsolete MB2061LD3W01 based on electrical and mechanical compatibility. Selection between the two substitute options should consider the following factors:

MPA206R: Active product status with ROHS3 compliance and extended electrical life (50,000 cycles). Ingress protection specification is not provided; applications requiring documented environmental sealing should evaluate this limitation.

MPE206R: Active product status with ROHS3 compliance, extended electrical life (50,000 cycles), and documented Splash Proof ingress protection. This option provides explicit environmental protection specification suitable for applications where moisture resistance is a design requirement.

Both substitutes exceed the original part's DC current rating (4A versus 3A) and electrical life (50,000 cycles versus 25,000 cycles), providing enhanced performance margins. The panel cutout diameter difference (6.35mm versus 6.50mm) is within acceptable mechanical tolerance for rear panel mount applications.

Frequently Asked Questions (FAQ)

Q: Can MPA206R or MPE206R be used as direct replacements for MB2061LD3W01?

A: Yes. Both substitute parts match the critical electrical parameters: DPDT circuit, On-Mom function, 6A AC at 125V, panel mount rear termination with solder lugs, and ROHS3 compliance. The 6.35mm panel cutout diameter is mechanically compatible with standard rear panel mount applications designed for the original 6.50mm specification.

Q: What is the difference between MPA206R and MPE206R?

A: Both parts are electrically identical with matching DPDT configuration, current ratings, and voltage specifications. The primary difference is ingress protection: MPE206R specifies Splash Proof protection, while MPA206R does not provide an ingress protection specification. For applications requiring documented environmental sealing, MPE206R is the appropriate selection.

Q: Are there any temperature range limitations with the substitute parts?

A: The substitute parts operate within -20°C to 80°C, which is narrower than the original MB2061LD3W01 range of -30°C to 85°C. Applications operating below -20°C or above 80°C require evaluation against actual system requirements.

Q: Do the substitute parts have better electrical life than the original?

A: Yes. Both MPA206R and MPE206R are rated for 50,000 electrical cycles, compared to 25,000 cycles for the MB2061LD3W01. This represents a 2x improvement in electrical life specification.

Q: What is the DC voltage rating difference between the original and substitutes?

A: The MB2061LD3W01 is rated for 30V DC, while MPA206R and MPE206R are rated for 28V DC. Both substitute parts meet or exceed the original DC current rating (4A versus 3A), providing adequate performance margin for most applications.
