MB2011LS1A01 Equivalent & Substitute Parts

Part Overview

The MB2011LS1A01 is a pushbutton switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 6A at 125V AC and 3A at 30V DC. Manufactured by NKK Switches as part of the MB2000 series, this component features a plunger actuator with solder lug termination and panel mount rear configuration. The product is currently obsolete, making equivalent substitute parts necessary for ongoing maintenance, repair, and new design implementations where this switch type is required.

Key Parameters

Substitute Part Grouping Explanation

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

Circuit and Electrical Compatibility:

• SPDT circuit configuration (required match)
• On-Mom switch function (required match)
• AC current rating minimum 6A
• AC voltage rating minimum 125V
• DC current rating minimum 3A
• DC voltage rating minimum 30V

Mechanical and Physical Compatibility:

• Panel mount rear configuration (required match)
• Plunger actuator type (required match)
• Solder lug termination (required match)
• Panel cutout diameter compatibility (6.50mm nominal)

Regulatory and Environmental:

• ROHS3 compliance (required match)
• MSL rating 1 or equivalent (required match)

The substitute parts MPA106F and MPE106F meet the core electrical circuit requirements and mechanical mounting specifications. Both are active products from TE Connectivity ALCOSWITCH Switches, providing continuity for applications requiring SPDT pushbutton switches with equivalent electrical performance.

Parameter Comparison

Engineering Selection Recommendations

Both MPA106F and MPE106F are qualified substitutes for the obsolete MB2011LS1A01 based on electrical and mechanical parameter alignment.

MPA106F Selection Criteria:

• Active product status ensures ongoing availability and supply chain continuity
• Meets all core electrical requirements (6A AC at 125V, 4A DC at 28V)
• ROHS3 compliant with MSL 1 rating
• Electrical life rating of 50,000 cycles exceeds the original specification
• Panel cutout diameter of 6.35mm is compatible with standard 6.50mm mounting holes

MPE106F Selection Criteria:

• Active product status with established supply chain
• Identical electrical specifications to MPA106F
• ROHS3 compliant with MSL 1 rating and REACH Affected designation
• Splash proof ingress protection provides enhanced environmental protection
• Electrical life rating of 50,000 cycles exceeds the original specification
• Panel cutout diameter of 6.35mm is compatible with standard 6.50mm mounting holes

Both substitutes are suitable for direct replacement in applications where the MB2011LS1A01 was originally specified. Selection between MPA106F and MPE106F depends on environmental exposure requirements, with MPE106F recommended for applications requiring splash proof protection.

Frequently Asked Questions (FAQ)

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

A: Both MPA106F and MPE106F meet the core electrical and mechanical requirements for substitution. The SPDT circuit configuration, On-Mom function, 6A AC rating at 125V, and panel mount rear configuration are identical. The primary difference is that MPE106F includes splash proof ingress protection, making it suitable for applications with moisture exposure.

Q: What are the differences in panel cutout dimensions?

A: The MB2011LS1A01 specifies a 6.50mm diameter circular cutout, while both MPA106F and MPE106F require 6.35mm diameter cutouts. The 0.15mm difference is within standard mechanical tolerance for panel mounting applications and does not prevent substitution.

Q: How do the operating temperature ranges compare?

A: The MB2011LS1A01 operates from -30°C to 85°C, while MPA106F and MPE106F operate from -20°C to 80°C. For applications requiring operation below -20°C or above 80°C, the original MB2011LS1A01 specification must be maintained if available from inventory.

Q: What is the significance of the electrical life rating difference?

A: The MB2011LS1A01 has an electrical life of 25,000 cycles, while both MPA106F and MPE106F are rated for 50,000 cycles. This indicates the substitute parts have extended operational longevity under electrical switching conditions.

Q: Are there compliance differences between the substitutes?

A: Both MPA106F and MPE106F are ROHS3 compliant with MSL 1 rating. MPE106F carries REACH Affected status, while MPA106F shows REACH Vendor Undefined. For applications in REACH-regulated markets, MPE106F provides explicit compliance documentation.

Q: Which substitute should be selected for new designs?

A: For new designs, either MPA106F or MPE106F is appropriate based on environmental requirements. MPE106F is recommended for applications with moisture exposure due to splash proof protection. Both are active products with established supply chains, ensuring long-term availability.
