MB2011LD3W01 Equivalent & Substitute Parts

Part Overview

The MB2011LD3W01 is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with 6A AC and 3A DC current ratings at 125V AC and 30V DC respectively. This component is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements. The switch employs panel mount rear termination with solder lug connections and IP67 ingress protection rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2011LD3W01 is determined by the following mandatory parameters:

• Circuit configuration must be SPDT
• Switch function must be On-Mom (momentary)
• AC current rating must be minimum 6A at 125V
• DC current rating must be minimum 3A at 30V
• Mounting type must be Panel Mount, Rear
• Termination style must be Solder Lug
• Actuator type must be Plunger for Cap
• Panel cutout diameter compatibility

The identified substitute parts MPA106F and MPE106F from TE Connectivity ALCOSWITCH Switches meet the core electrical and mechanical requirements. Both parts maintain SPDT circuit configuration, On-Mom function, 6A AC at 125V rating, and panel mount rear solder lug termination. However, DC current ratings (4A) and voltage ratings (28V DC) exceed the minimum requirements of the original part. Panel cutout diameter differs at 6.35mm versus 6.50mm, requiring mechanical evaluation for panel compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both MPA106F and MPE106F are active products from TE Connectivity ALCOSWITCH Switches and represent viable alternatives to the obsolete MB2011LD3W01. Selection between these two substitutes should be based on the following criteria:

MPA106F is suitable for applications where ingress protection specifications are not explicitly required or where splash resistance is not a design constraint. This part maintains full ROHS3 compliance and unlimited moisture sensitivity rating.

MPE106F is recommended for applications requiring enhanced environmental protection. This part provides splash-proof ingress protection, exceeding the environmental durability of the original MB2011LD3W01 while maintaining ROHS3 compliance. REACH Affected status indicates regulatory compliance documentation is available.

Both substitutes exceed the original part's DC current and voltage specifications, providing design margin. The reduced operating temperature range (-20°C to 80°C versus -30°C to 85°C) and panel cutout diameter reduction (6.35mm versus 6.50mm) require mechanical and thermal evaluation within specific application contexts.

Frequently Asked Questions (FAQ)

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

A: Both parts satisfy the core electrical requirements (SPDT circuit, 6A AC at 125V, On-Mom function, solder lug termination). Panel cutout diameter differs by 0.15mm, requiring mechanical verification for panel compatibility. MPE106F provides splash-proof protection versus the original IP67 rating.

Q: What is the impact of the 6.35mm panel cutout diameter on compatibility?

A: The original MB2011LD3W01 requires a 6.50mm circular panel cutout. Both substitute parts require 6.35mm cutout diameter. Existing panel tooling designed for 6.50mm will not accommodate 6.35mm diameter switches without modification.

Q: Are there differences in electrical life between the original and substitute parts?

A: The MB2011LD3W01 specifies 25,000 cycles electrical life. Both MPA106F and MPE106F provide 50,000 cycles electrical life, representing a 2x improvement in rated electrical endurance.

Q: What is the significance of the operating temperature range difference?

A: The original part operates from -30°C to 85°C. Substitute parts operate from -20°C to 80°C. Applications requiring operation below -20°C or above 80°C cannot use these substitutes without thermal analysis and potential derating.

Q: How do the DC voltage ratings compare?

A: The MB2011LD3W01 is rated for 30V DC. Both substitute parts are rated for 28V DC. For applications operating at or near 30V DC, the reduced rating requires circuit evaluation to confirm adequate design margin.

Q: What is the difference between MPA106F and MPE106F regarding environmental protection?

A: MPA106F does not specify ingress protection rating. MPE106F provides splash-proof protection. For applications requiring IP67 dust-tight and waterproof performance equivalent to the original part, MPE106F is the more appropriate selection.
