Key Parameters

Substitute Part Grouping Explanation

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

Mandatory Matching Parameters:

• Circuit configuration: SPDT
• Switch function: On-Mom
• Current rating: 6A AC minimum
• Voltage rating: 125V AC minimum
• Mounting type: Panel Mount, Rear
• Termination style: Solder Lug
• Panel cutout diameter: 6.35mm to 6.50mm (compatible with standard panel openings)

Acceptable Variation Parameters:

• DC current rating: 3A or higher
• DC voltage rating: 28V or higher
• Operating temperature range: -20°C to 85°C or broader
• Electrical life: 25,000 cycles or higher
• Mechanical life: Data provided or unspecified

The substitute parts MPA106F and MPE106F meet all mandatory matching criteria while providing equal or superior electrical performance characteristics. Both alternatives are manufactured by TE Connectivity ALCOSWITCH Switches and maintain active product status, ensuring long-term availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

Both MPA106F and MPE106F are qualified substitutes for the obsolete MB2011LS1A01-BA based on electrical parameter compatibility and active product status.

MPA106F Selection Criteria:

• Suitable for standard industrial control applications requiring SPDT switching at 6A AC / 4A DC
• Active product status ensures availability and manufacturer support
• ROHS3 compliant with unlimited moisture sensitivity level
• Electrical life rating of 50,000 cycles exceeds original specification
• Panel cutout diameter of 6.35mm requires verification for existing panel openings designed for 6.50mm

MPE106F Selection Criteria:

• Provides identical electrical performance to MPA106F with additional splash proof ingress protection
• Recommended for applications requiring environmental protection beyond standard panel mount configurations
• REACH Affected status requires compliance verification in regulated markets
• Electrical life rating of 50,000 cycles exceeds original specification
• Panel cutout diameter of 6.35mm requires verification for existing panel openings designed for 6.50mm

Both alternatives maintain ROHS3 compliance and EAR99 export classification consistent with the original component.

Frequently Asked Questions (FAQ)

Q: Can MPA106F and MPE106F be used interchangeably with MB2011LS1A01-BA?

A: Both parts meet the mandatory electrical and mechanical parameters for direct substitution. The primary consideration is panel cutout diameter: the original part requires 6.50mm, while substitutes require 6.35mm. Existing panel openings may require modification or use of adapter rings.

Q: What is the difference between MPA106F and MPE106F?

A: Both parts share identical electrical ratings and circuit configuration. MPE106F includes splash proof ingress protection, making it suitable for applications with moisture or liquid exposure. MPA106F is specified for standard dry environments. Selection depends on application environmental requirements.

Q: Why is the DC voltage rating lower on substitute parts (28V vs 30V)?

A: The substitute parts are rated at 28V DC, which is within acceptable tolerance for most DC applications. Applications requiring operation at exactly 30V DC should be evaluated against actual circuit requirements. Both ratings exceed typical industrial control circuit voltages.

Q: Are there inventory considerations for these substitutes?

A: MPA106F has 1,578 units in stock and MPE106F has 1,039 units in stock, providing immediate availability. The original MB2011LS1A01-BA is obsolete with no ongoing production.

Q: What compliance certifications apply to these parts?

A: All three parts are ROHS3 compliant. MPA106F has undefined REACH status, while MPE106F is REACH Affected. Applications in regulated markets must verify compliance requirements before selection.

Q: Is mechanical life data available for substitute parts?

A: Mechanical life specifications are not provided for MPA106F and MPE106F. Electrical life ratings of 50,000 cycles are specified for both substitutes, exceeding the original part's 25,000 cycle rating.
