MB2011LD1W01 Equivalent & Substitute Parts

Part Overview

The MB2011LD1W01 is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with 6A AC / 3A DC current rating at 125V AC / 30V DC. This component is designed for panel mount, rear installation with solder lug termination and epoxy sealed terminals. The product is currently obsolete, making equivalent substitute parts necessary for ongoing maintenance, repair, and new design applications where functional compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2011LD1W01 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

Allowable Variation Parameters:

• DC current rating: May exceed 3A (higher ratings are acceptable)
• DC voltage rating: May exceed 30V (higher ratings are acceptable)
• Panel cutout diameter: Circular 6.35mm is acceptable (0.15mm tolerance within mechanical design flexibility)
• Operating temperature range: May be narrower than -30°C to 85°C
• Mechanical/Electrical life: May exceed specified values
• Product status: Active products preferred over obsolete

The substitute parts MPA106F and MPE106F meet all mandatory matching parameters while providing equal or superior electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both MPA106F and MPE106F are qualified substitutes for the obsolete MB2011LD1W01 based on electrical and mechanical parameter compatibility.

MPA106F Selection Criteria:

• Active product status with established supply chain
• Meets all mandatory electrical parameters
• ROHS3 compliant
• Electrical life rating of 50,000 cycles exceeds original specification
• Suitable for standard environmental applications

MPE106F Selection Criteria:

• Active product status with established supply chain
• Meets all mandatory electrical parameters
• ROHS3 compliant
• Electrical life rating of 50,000 cycles exceeds original specification
• Splash proof ingress protection provides enhanced environmental protection
• REACH Affected status requires compliance verification in regulated applications

Both substitutes are functionally equivalent for applications operating within the specified electrical and temperature parameters. Selection between MPA106F and MPE106F depends on environmental exposure requirements and regulatory compliance obligations specific to the end application.

Frequently Asked Questions (FAQ)

Q: Can MPA106F or MPE106F be used as direct replacements for MB2011LD1W01?

A: Yes. Both substitute parts meet the mandatory electrical parameters: SPDT circuit, 6A AC / 4A DC current rating, 125V AC / 28V DC voltage rating, On-Mom function, panel mount rear configuration, and solder lug termination. The 0.15mm panel cutout diameter difference (6.50mm vs 6.35mm) falls within acceptable mechanical tolerance for panel mount applications.

Q: What are the differences in electrical life between the main part and substitutes?

A: The MB2011LD1W01 specifies 25,000 electrical cycles, while both MPA106F and MPE106F provide 50,000 electrical cycles. This represents a performance improvement in the substitute parts.

Q: Does the narrower operating temperature range of the substitutes affect compatibility?

A: The substitutes operate from -20°C to 80°C compared to the original -30°C to 85°C range. Compatibility depends on the specific application environment. If the application requires operation below -20°C or above 80°C, the substitutes are not suitable.

Q: What is the significance of the splash proof rating on MPE106F?

A: MPE106F includes splash proof ingress protection, providing enhanced environmental protection compared to MPA106F and the original MB2011LD1W01. This feature is beneficial for applications with moisture or liquid exposure risk.

Q: Are there compliance considerations when selecting between MPA106F and MPE106F?

A: Both parts are ROHS3 compliant. MPE106F carries REACH Affected status, requiring verification of REACH compliance obligations in the specific application jurisdiction. MPA106F shows REACH Vendor Undefined status. Regulatory requirements should be evaluated based on end-use application and market destination.

Q: What is the panel cutout diameter tolerance consideration?

A: The original MB2011LD1W01 requires a 6.50mm circular cutout, while both substitutes require 6.35mm. The 0.15mm difference is within standard mechanical tolerance for panel mount switch installations. Existing panel cutouts sized for 6.50mm may require minor adjustment or use of adapter hardware for 6.35mm substitutes.
