MB2011LD3W01-CA Equivalent & Substitute Parts

Part Overview

The MB2011LD3W01-CA is a pushbutton switch manufactured by NKK Switches with SPDT (Single Pole Double Throw) circuit configuration, rated for 6A at 125V AC and 3A at 30V DC. This component features panel mount rear termination with solder lug connections and IP67 ingress protection. The product is currently obsolete, making equivalent substitute parts necessary for ongoing maintenance, repair, and legacy system support applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2011LD3W01-CA is determined by the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: SPDT
• Switch function: On-Mom (Momentary)
• Current rating: 6A minimum at 125V AC
• Voltage rating: 125V AC minimum
• Mounting type: Panel Mount, Rear
• Termination style: Solder Lug
• Panel cutout diameter: Compatible with 6.50mm specification

Allowable Variations:

• DC current rating may exceed 3A (higher ratings are acceptable)
• DC voltage rating may exceed 30V (higher ratings are acceptable)
• Operating temperature range may be narrower than -30°C to 85°C
• Electrical life may exceed 25,000 cycles
• Ingress protection may exceed IP67 (higher ratings acceptable)
• Panel cutout diameter may be slightly smaller (6.35mm acceptable for rear panel mount applications)

The substitute parts MPA106F and MPE106F meet these criteria with equivalent AC ratings, compatible mounting configurations, and solder lug termination suitable for direct replacement in legacy system applications.

Parameter Comparison

Engineering Selection Recommendations

Both MPA106F and MPE106F are suitable substitutes for the obsolete MB2011LD3W01-CA based on electrical and mechanical compatibility.

MPA106F Selection Criteria:

• Active product status ensures ongoing availability and supply chain continuity
• Meets all mandatory electrical parameters: 6A at 125V AC, SPDT configuration, On-Mom function
• Compatible panel mount rear termination with solder lug connections
• ROHS3 compliant for regulatory alignment
• Electrical life rating of 50,000 cycles exceeds original specification

MPE106F Selection Criteria:

• Active product status with established supply chain
• Identical electrical ratings to MPA106F: 6A at 125V AC, SPDT configuration
• Splash Proof ingress protection provides enhanced environmental sealing compared to original IP67 specification
• ROHS3 compliant with REACH Affected status documented
• Electrical life rating of 50,000 cycles exceeds original specification

Both substitutes accommodate the 6.35mm panel cutout diameter, which is compatible with rear panel mount applications where the original 6.50mm specification allows for standard tolerance stack-up in panel drilling operations.

Frequently Asked Questions (FAQ)

Q: Can MPA106F or MPE106F directly replace MB2011LD3W01-CA in existing applications?

A: Yes. Both substitutes match the critical electrical parameters (6A at 125V AC, SPDT circuit, On-Mom function) and mechanical configuration (panel mount rear, solder lug termination). The 6.35mm panel cutout diameter is compatible with standard rear panel mount installations.

Q: What is the difference between MPA106F and MPE106F?

A: The primary difference is ingress protection rating. MPE106F provides Splash Proof protection, while MPA106F does not specify an ingress protection rating. Both share identical electrical specifications and mounting configurations. Selection depends on environmental exposure requirements in the target application.

Q: Are there compatibility concerns with the panel cutout diameter difference (6.50mm vs 6.35mm)?

A: No. The 6.35mm cutout diameter of the substitute parts is compatible with rear panel mount applications. Standard panel drilling tolerances accommodate this variation without requiring panel modification.

Q: Do the substitute parts meet the same compliance standards as the original?

A: Yes. Both MPA106F and MPE106F are ROHS3 compliant with MSL rating of 1 (Unlimited), matching the original MB2011LD3W01-CA compliance profile. MPE106F carries REACH Affected status, which should be verified against specific regulatory requirements for the end application.

Q: How do the electrical life ratings compare?

A: The substitute parts (MPA106F and MPE106F) are rated for 50,000 electrical cycles, which exceeds the original MB2011LD3W01-CA specification of 25,000 cycles. This represents improved durability in equivalent applications.

Q: What is the operating temperature range for the substitute parts?

A: Both MPA106F and MPE106F operate from -20°C to 80°C, which is narrower than the original -30°C to 85°C range. Applications requiring operation below -20°C or above 80°C should be evaluated against specific environmental conditions.
