MB2011LS4W01-CH Equivalent & Substitute Parts

Part Overview

The MB2011LS4W01-CH is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with 6A AC / 3A DC current rating and 125V AC / 30V DC voltage rating. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement continuity. The switch employs panel mount rear termination with solder lug connections and operates across -30°C to 85°C temperature range with 100,000 mechanical cycles and 25,000 electrical cycles rated life.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2011LS4W01-CH is determined by strict alignment across the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: SPDT
• Switch function: On-Momentary
• AC current rating: 6A minimum
• AC voltage rating: 125V minimum
• Mounting type: Panel Mount, Rear
• Termination style: Solder Lug
• RoHS compliance: ROHS3 Compliant

Allowable Variations:

• DC current rating: Substitute may exceed 3A specification
• DC voltage rating: Substitute may exceed 30V specification
• Panel cutout diameter: Circular geometry maintained; minor diameter variance acceptable within mechanical tolerance
• Operating temperature range: Substitute may have narrower range if minimum -20°C and maximum 80°C are met
• Electrical life: Substitute may exceed 25,000 cycles specification
• Mechanical life: Data not required for substitutes if not provided

The substitute parts MPA106F and MPE106F meet all mandatory parameters while providing enhanced DC current ratings (4A) and electrical life (50,000 cycles). Both maintain ROHS3 compliance and panel mount rear configuration with solder lug termination.

Parameter Comparison

Engineering Selection Recommendations

Both MPA106F and MPE106F are active production components from TE Connectivity ALCOSWITCH Switches and serve as direct functional equivalents to the obsolete MB2011LS4W01-CH.

MPA106F Selection Criteria:

• Suitable for applications requiring standard environmental protection
• Active product status ensures long-term availability and supply chain stability
• ROHS3 compliance maintained
• Enhanced electrical life (50,000 cycles) provides extended operational durability compared to original specification

MPE106F Selection Criteria:

• Recommended for applications requiring splash proof ingress protection
• Active product status with established supply chain
• ROHS3 compliance maintained
• Enhanced electrical life (50,000 cycles) with additional environmental sealing
• REACH Affected status requires compliance verification in regulated markets

Panel Cutout Consideration: Both substitute parts feature 6.35mm circular panel cutout diameter versus the original 6.50mm specification. Mechanical panel modifications may be required for direct retrofit applications. Verify panel mounting hole dimensions before component selection.

Temperature Range Consideration: Substitute parts operate within -20°C to 80°C range, which is narrower than the original -30°C to 85°C specification. Applications requiring operation below -20°C or above 80°C require alternative component selection.

Frequently Asked Questions (FAQ)

Q: Can MPA106F and MPE106F be used interchangeably with MB2011LS4W01-CH?

A: Both parts meet the mandatory electrical specifications (SPDT circuit, 6A AC, 125V AC, On-Momentary function, solder lug termination). However, panel cutout diameter differs (6.35mm versus 6.50mm), requiring mechanical panel assessment. Operating temperature range is narrower (-20°C to 80°C versus -30°C to 85°C). Verify application requirements before substitution.

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, requiring compliance verification in regulated applications. MPA106F REACH status is vendor undefined. Select based on environmental protection requirements and regulatory compliance needs.

Q: Are the substitute parts RoHS compliant?

A: Yes, both MPA106F and MPE106F are ROHS3 compliant, matching the original MB2011LS4W01-CH specification.

Q: What is the impact of the 0.15mm panel cutout diameter difference?

A: The substitute parts feature 6.35mm circular cutout versus the original 6.50mm. This 0.15mm reduction may require panel modification or use of adapter hardware for direct retrofit. Measure existing panel mounting holes to determine if mechanical adjustment is necessary.

Q: Do the substitute parts have better electrical life ratings?

A: Yes, both MPA106F and MPE106F are rated for 50,000 electrical cycles compared to the original 25,000 cycles specification, providing doubled operational durability.

Q: Which substitute part should be selected for outdoor applications?

A: MPE106F is recommended for outdoor or splash-prone environments due to splash proof ingress protection. MPA106F lacks specified ingress protection and is suitable for standard indoor panel mount applications.
