MB2011LD1W01-CA Equivalent & Substitute Parts

Part Overview

The MB2011LD1W01-CA 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. Substitute parts must maintain electrical performance specifications and mechanical compatibility within the specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2011LD1W01-CA is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration must be SPDT
• Switch function must be On-Mom
• AC current rating must support minimum 6A at 125V
• DC current rating must support minimum 3A at 30V
• AC voltage rating must be 125V or higher
• DC voltage rating must be 30V or higher

Mechanical Compatibility Requirements:

• Mounting type must be Panel Mount, Rear
• Termination style must be Solder Lug
• Panel cutout diameter must accommodate 6.50mm specification

Regulatory & Environmental Requirements:

• RoHS3 compliance required
• MSL rating of 1 (Unlimited) required
• Operating temperature range must encompass -30°C to 85°C minimum

The substitute parts MPA106F and MPE106F meet the electrical circuit requirements (SPDT, On-Mom function) and maintain AC voltage/current specifications. However, both substitutes present parameter deviations that must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both MPA106F and MPE106F are active products from TE Connectivity ALCOSWITCH Switches and maintain ROHS3 compliance with MSL rating 1 (Unlimited), satisfying regulatory requirements for the obsolete MB2011LD1W01-CA.

MPA106F Considerations:

• Meets AC electrical specifications (6A at 125V)
• DC current rating of 4A exceeds minimum 3A requirement
• DC voltage rating of 28V is below the original 30V specification
• Operating temperature range of -20°C to 80°C is narrower than original -30°C to 85°C
• Panel cutout diameter of 6.35mm differs from 6.50mm, requiring mechanical evaluation
• REACH status undefined by vendor

MPE106F Considerations:

• Meets AC electrical specifications (6A at 125V)
• DC current rating of 4A exceeds minimum 3A requirement
• DC voltage rating of 28V is below the original 30V specification
• Operating temperature range of -20°C to 80°C is narrower than original -30°C to 85°C
• Panel cutout diameter of 6.35mm differs from 6.50mm, requiring mechanical evaluation
• Provides Splash Proof ingress protection
• REACH Affected status documented

Selection between MPA106F and MPE106F depends on application-specific requirements for environmental protection and regulatory compliance in target markets.

Frequently Asked Questions (FAQ)

Q: Can MPA106F or MPE106F directly replace MB2011LD1W01-CA in existing designs?

A: Both parts maintain SPDT circuit configuration and On-Mom switch function with matching AC specifications. However, panel cutout diameter differs (6.35mm vs. 6.50mm), requiring mechanical panel modification. DC voltage rating is 28V versus the original 30V specification. Operating temperature range is narrower (-20°C to 80°C vs. -30°C to 85°C). Application-specific evaluation is required.

Q: What are the key electrical differences between the substitute parts and the original?

A: The original MB2011LD1W01-CA specifies 3A DC current at 30V DC. Both MPA106F and MPE106F provide 4A DC current at 28V DC. AC specifications remain identical at 6A at 125V. The DC voltage reduction from 30V to 28V may impact applications operating at the upper DC voltage limit.

Q: How do the mechanical specifications differ?

A: Panel cutout diameter is 6.35mm for both substitutes versus 6.50mm for the original. This 0.15mm difference requires panel modification or use of adapter hardware. All three parts maintain Panel Mount, Rear configuration with Solder Lug termination.

Q: What is the difference between MPA106F and MPE106F?

A: Both parts share identical electrical and thermal specifications. MPE106F provides Splash Proof ingress protection, while MPA106F does not specify ingress protection. MPE106F is REACH Affected; MPA106F has undefined REACH status.

Q: Are there inventory considerations for these substitutes?

A: MPA106F has 1578 pieces in stock; MPE106F has 1039 pieces in stock. Both are active products with ongoing availability.
