MB2011LS1A01-CA Equivalent & Substitute Parts

Part Overview

The MB2011LS1A01-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. The part employs panel mount rear termination with solder lug connections and epoxy sealed terminals suitable for industrial control applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2011LS1A01-CA is determined by the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: SPDT
• Switch function: On-Mom
• AC current rating: 6A minimum
• AC voltage rating: 125V minimum
• Mounting type: Panel Mount, Rear
• Termination style: Solder Lug

Allowable Variations:

• DC current rating: Substitute must meet or exceed 3A DC
• DC voltage rating: Substitute must meet or exceed 30V DC
• Panel cutout diameter: Circular configuration with tolerance for mechanical fit
• Operating temperature range: Substitute may have narrower range if application requirements are met
• Electrical life: Substitute may differ from original specification

The identified substitutes MPA106F and MPE106F from TE Connectivity ALCOSWITCH Switches meet all mandatory parameters while maintaining functional equivalence for SPDT pushbutton switch applications.

Parameter Comparison

Engineering Selection Recommendations

Both MPA106F and MPE106F are active products from TE Connectivity ALCOSWITCH Switches and serve as functional equivalents to the obsolete MB2011LS1A01-CA. Both substitutes are ROHS3 compliant and maintain electrical compatibility across standard industrial control voltage and current specifications.

MPA106F provides a direct functional replacement with equivalent electrical ratings and active product status, suitable for applications where the original operating temperature range of -30°C to 85°C can be accommodated within the narrower -20°C to 80°C specification.

MPE106F offers the same electrical equivalence as MPA106F with the additional feature of splash proof ingress protection, providing enhanced environmental resilience for applications requiring moisture resistance. This variant is REACH Affected, requiring compliance verification for specific end-use applications.

Selection between MPA106F and MPE106F depends on environmental exposure requirements and regulatory compliance obligations specific to the application.

Frequently Asked Questions (FAQ)

Q: Can MPA106F or MPE106F directly replace MB2011LS1A01-CA in existing designs?

A: Both substitutes maintain SPDT circuit configuration, On-Mom switch function, 6A AC current rating, and 125V AC voltage rating. Panel cutout diameter differs by 0.15mm (6.50mm vs 6.35mm), requiring mechanical fit verification. Electrical life is doubled in both substitutes (50,000 vs 25,000 cycles), providing improved durability.

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

A: The MB2011LS1A01-CA requires a 6.50mm circular cutout, while both MPA106F and MPE106F require 6.35mm. Existing panel tooling designed for 6.50mm will require modification or reaming to accommodate the substitute parts.

Q: Are there compliance differences between MPA106F and MPE106F?

A: Both are ROHS3 compliant. MPE106F is REACH Affected, while MPA106F shows REACH status as Vendor Undefined. Applications subject to REACH regulations should verify compliance requirements with the component supplier.

Q: How do the operating temperature ranges compare?

A: MB2011LS1A01-CA operates from -30°C to 85°C. Both substitutes operate from -20°C to 80°C, representing a narrower range. Applications requiring operation below -20°C or above 80°C cannot use these substitutes.

Q: What is the advantage of MPE106F over MPA106F?

A: MPE106F includes splash proof ingress protection, providing enhanced environmental resistance. Both parts are otherwise electrically equivalent. Selection depends on application environmental exposure requirements.

Q: Are the DC current and voltage ratings sufficient for substitution?

A: MB2011LS1A01-CA is rated 3A DC at 30V DC. Both substitutes are rated 4A DC at 28V DC. The higher DC current rating in substitutes exceeds the original requirement. The 2V reduction in DC voltage rating (30V to 28V) must be evaluated against specific application requirements.
