MB2011LD3W01-CH Equivalent & Substitute Parts

Part Overview

The MB2011LD3W01-CH 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-CH is determined by the following critical parameters:

Mandatory Matching Parameters:

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

Allowable Variation Parameters:

• DC current rating: Substitute must meet or exceed 3A
• DC voltage rating: Substitute must meet or exceed 30V
• Operating temperature range: Substitute must cover or exceed the specified range
• Electrical life: Substitute must meet or exceed 25,000 cycles
• Ingress protection: Equal or superior rating acceptable

The substitute parts MPA106F and MPE106F meet the mandatory electrical and mechanical parameters while maintaining functional equivalence for panel-mounted SPDT pushbutton switch applications.

Parameter Comparison

Engineering Selection Recommendations

Both MPA106F and MPE106F are active production alternatives to the obsolete MB2011LD3W01-CH. Selection between these substitutes is based on the following engineering criteria:

MPA106F Selection Criteria:

• Applications requiring standard electrical performance without enhanced environmental protection
• Systems where ingress protection specification is not critical
• Cost-optimized designs where splash protection is not required
• ROHS3 compliant requirement met; REACH status vendor undefined

MPE106F Selection Criteria:

• Applications requiring splash-proof environmental protection
• Systems operating in moisture-prone or washdown environments
• REACH Affected designation indicates full regulatory compliance documentation
• Enhanced electrical life rating (50,000 cycles) provides extended service intervals

Both substitutes provide superior electrical life (50,000 cycles versus 25,000 cycles) and higher DC current ratings (4A versus 3A) compared to the main part. Panel cutout diameter difference (6.35mm versus 6.50mm) requires mechanical panel evaluation for retrofit applications.

Frequently Asked Questions (FAQ)

Q: Can MPA106F or MPE106F directly replace MB2011LD3W01-CH in existing applications?

A: Both parts meet the mandatory electrical parameters (SPDT circuit, 6A AC at 125V, On-Mom function, solder lug termination). Panel cutout diameter differs by 0.15mm (6.35mm versus 6.50mm), requiring mechanical panel assessment. DC voltage rating is 28V versus 30V, which is acceptable for most applications but must be verified against circuit requirements.

Q: What is the difference between MPA106F and MPE106F?

A: Both parts share identical electrical ratings and circuit configuration. MPE106F provides splash-proof ingress protection, while MPA106F does not specify ingress protection. MPE106F carries REACH Affected status, indicating full regulatory compliance documentation. Selection depends on environmental exposure requirements.

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

A: Both MPA106F and MPE106F operate from -20°C to 80°C, compared to the original part's -30°C to 85°C range. Applications requiring operation below -20°C or above 80°C must be evaluated against actual system requirements.

Q: Do the substitute parts meet RoHS compliance?

A: Both MPA106F and MPE106F are ROHS3 compliant, matching the original MB2011LD3W01-CH specification.

Q: What is the mechanical life expectancy of the substitute parts?

A: Mechanical life specifications are not provided for MPA106F or MPE106F. Both parts specify 50,000 cycles electrical life, which exceeds the original part's 25,000 cycles rating.

Q: How does the panel cutout diameter difference affect installation?

A: The substitute parts require 6.35mm diameter cutouts versus 6.50mm for the original part. Existing panel holes may require enlargement or new panel fabrication for retrofit applications. Mechanical compatibility must be confirmed before installation.
