MB2011LS1G01-CC Equivalent & Substitute Parts

Part Overview

The MB2011LS1G01-CC is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with 0.4VA rating at 28V. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations. The switch is designed for panel mount rear installation with solder lug termination and epoxy sealed terminals.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2011LS1G01-CC is determined by the following critical parameters:

Circuit configuration must remain SPDT to maintain electrical functionality within the host system. Switch function must be On-Mom (momentary action) to preserve operational behavior. Mounting type must be Panel Mount, Rear to ensure mechanical compatibility with existing panel cutouts and installation procedures. Termination style must be Solder Lug for compatibility with PCB assembly processes.

Voltage and current ratings must meet or exceed the original specification. The substitute part 1977737-2 satisfies these core requirements: it maintains SPDT circuit configuration, On-Mom function, Panel Mount Rear mounting, and Solder Lug termination. The voltage rating of 30V DC exceeds the 28V requirement. The current rating of 60mA DC is lower than the original 0.4VA specification, making this substitute suitable only for applications where the actual current draw does not exceed 60mA.

Parameter Comparison

Engineering Selection Recommendations

The 1977737-2 from TE Connectivity ALCOSWITCH Switches is an active product with ROHS3 compliance, providing supply chain continuity for the obsolete MB2011LS1G01-CC. Both components meet RoHS3 requirements and share identical electrical life ratings of 50,000 cycles.

Selection of the 1977737-2 substitute requires verification that the application current draw does not exceed 60mA DC. The substitute operates within a narrower temperature range (-20°C to 80°C versus -30°C to 85°C), which may impact suitability for extreme environment applications. The mechanical life specification is not provided for the substitute part, whereas the original specifies 100,000 cycles.

Frequently Asked Questions (FAQ)

Q: Can the 1977737-2 directly replace the MB2011LS1G01-CC in all applications?

A: Direct replacement is possible only when the application current draw does not exceed 60mA DC. The original part is rated for 0.4VA, which is significantly higher. Applications operating at higher current levels require alternative substitutes or the original component through legacy supply channels.

Q: What are the key differences between these two switches?

A: The primary differences are current rating (0.4VA versus 60mA), operating temperature range (-30°C to 85°C versus -20°C to 80°C), and product status (obsolete versus active). Both maintain identical circuit configuration, switch function, mounting type, and termination style.

Q: Are both parts RoHS compliant?

A: Yes, both the MB2011LS1G01-CC and 1977737-2 are ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: Does the actuator type difference affect compatibility?

A: The actuator type difference (round button versus plunger for cap) affects the physical appearance and user interface but does not impact electrical compatibility. Panel cutout dimensions must be verified for mechanical fit, as the original specifies a circular 6.50mm diameter cutout while the substitute does not provide this specification.

Q: What is the inventory status for these parts?

A: The MB2011LS1G01-CC has 732 pieces available as new original stock. The 1977737-2 has 1048 pieces available as new original stock in bulk packaging.
