MB2011LD3W01-BA Equivalent & Substitute Parts

Part Overview

The MB2011LD3W01-BA is a pushbutton switch manufactured by NKK Switches with SPDT (Single Pole Double Throw) circuit configuration, 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 MB2011LD3W01-BA is determined by the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: SPDT
• Switch function: On-Mom (Momentary)
• Current rating: 6A minimum at 125V AC
• Voltage rating: 125V AC minimum
• Mounting type: Panel Mount, Rear
• Termination style: Solder Lug
• Panel cutout diameter: Compatible with 6.50mm specification

Acceptable Variation Parameters:

• DC current rating: May exceed 3A specification
• DC voltage rating: May exceed 30V specification
• Operating temperature range: May be narrower than -30°C to 85°C
• Mechanical/Electrical life: May exceed specified cycles
• Ingress protection: May exceed IP67 specification

The substitute parts MPA106F and MPE106F meet the mandatory matching criteria while maintaining electrical and mechanical compatibility with the MB2011LD3W01-BA in panel mount applications requiring SPDT momentary switching at 6A/125V AC.

Parameter Comparison

Engineering Selection Recommendations

Both MPA106F and MPE106F are active product alternatives to the obsolete MB2011LD3W01-BA. Selection between these substitutes should be based on the following factors:

MPA106F Selection Criteria:

• Applications where ingress protection specification is not critical
• Systems operating within -20°C to 80°C temperature range
• DC voltage requirements at or below 28V
• ROHS3 compliance required with vendor-undefined REACH status

MPE106F Selection Criteria:

• Applications requiring splash-proof ingress protection
• Systems operating within -20°C to 80°C temperature range
• DC voltage requirements at or below 28V
• ROHS3 compliance and REACH Affected status required for regulated supply chains

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 difference (6.35mm versus 6.50mm) requires mechanical panel evaluation for fit compatibility.

Frequently Asked Questions (FAQ)

Q: Can MPA106F and MPE106F be used interchangeably with MB2011LD3W01-BA?

A: Both parts meet the core electrical requirements (SPDT, 6A/125V AC, On-Mom function, panel mount rear termination with solder lugs). The primary consideration is panel cutout diameter: the substitutes require 6.35mm versus the original 6.50mm specification. Mechanical panel compatibility must be verified before installation.

Q: What is the difference between MPA106F and MPE106F?

A: Both parts share identical electrical ratings and operating characteristics. The key difference is ingress protection: MPE106F provides splash-proof protection while MPA106F does not specify ingress protection. MPE106F also carries REACH Affected status versus MPA106F's vendor-undefined REACH status. Select based on environmental exposure requirements and supply chain compliance needs.

Q: Are the substitute parts suitable for the full temperature range of the original MB2011LD3W01-BA?

A: The substitute parts operate from -20°C to 80°C, which is narrower than the original specification of -30°C to 85°C. Applications requiring operation below -20°C or above 80°C require alternative solutions.

Q: Do the substitute parts meet RoHS compliance?

A: Yes, both MPA106F and MPE106F are ROHS3 compliant, matching the original MB2011LD3W01-BA compliance status.

Q: What is the impact of the panel cutout diameter difference?

A: The original part specifies 6.50mm diameter while substitutes require 6.35mm. This 0.15mm difference may allow the substitute to fit in the original panel opening with slight clearance, but mechanical panel evaluation is necessary to confirm fit and ensure proper seating and retention.

Q: Do the substitute parts provide better reliability than the original?

A: The substitute parts specify 50,000 electrical life cycles compared to 25,000 cycles for the original MB2011LD3W01-BA, indicating extended operational life under specified electrical conditions.
