MB2011LD1G01-CC Equivalent & Substitute Parts

Part Overview

The MB2011LD1G01-CC is a pushbutton switch manufactured by NKK Switches, classified as SPDT (Single Pole Double Throw) with On-Momentary function. This component is rated for 0.4VA at 28V AC/DC and features a red round button actuator with solder lug termination for panel mount, rear installation. The product is currently obsolete, making identification of functionally equivalent alternatives necessary for system maintenance, repair, and redesign applications where continued supply cannot be guaranteed.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2011LD1G01-CC is determined by the following critical parameters:

• Circuit Configuration: Must be SPDT to maintain identical switching logic
• Switch Function: Must be On-Momentary to preserve operational behavior
• Mounting Type: Must be Panel Mount, Rear to ensure mechanical compatibility
• Termination Style: Must be Solder Lug for PCB integration compatibility
• Voltage Rating: Substitute must meet or exceed 28V DC rating
• Current Rating: Substitute must handle the electrical load requirements
• Electrical Life: Minimum 50,000 cycles required for equivalent reliability

The substitute part 1977737-2 (TE Connectivity ALCOSWITCH Switches) meets these core substitution criteria across circuit topology, mounting configuration, and termination method.

Parameter Comparison

Engineering Selection Recommendations

The 1977737-2 from TE Connectivity ALCOSWITCH Switches is a functionally equivalent substitute for the obsolete MB2011LD1G01-CC based on the following engineering criteria:

Electrical Compatibility: Both components share identical SPDT circuit configuration and On-Momentary switching function. The substitute's 30V DC rating exceeds the original 28V requirement. Current rating differs: the original supports 0.4VA (AC/DC) while the substitute is rated for 60mA DC. Applications operating at DC with loads not exceeding 60mA will function identically.

Mechanical Compatibility: Both switches feature Panel Mount, Rear installation and Solder Lug termination, ensuring direct PCB integration without redesign. Actuator geometry differs (round button versus plunger for cap), but functional operation remains equivalent.

Compliance & Reliability: Both components are ROHS3 compliant and rated for 50,000 electrical cycles. The substitute is in active production status, ensuring long-term availability and supply chain stability compared to the obsolete original.

Temperature Consideration: The substitute operates across -20°C to 80°C versus the original's -30°C to 85°C range. Applications requiring operation below -20°C or above 80°C require alternative evaluation.

Frequently Asked Questions (FAQ)

Q: Can the 1977737-2 directly replace the MB2011LD1G01-CC without PCB modification?

A: Yes, for applications within the electrical and thermal specifications. Both components use identical Panel Mount, Rear mounting and Solder Lug termination. Physical footprint compatibility should be confirmed through dimensional drawings, as actuator geometry differs.

Q: What is the primary electrical difference between these two switches?

A: The original MB2011LD1G01-CC is rated for 0.4VA at both AC and DC, while the 1977737-2 is rated for 60mA DC only. The substitute is suitable for DC applications with loads not exceeding 60mA. AC applications or higher current requirements require alternative components.

Q: Is the 1977737-2 suitable for the full temperature range of the original?

A: No. The substitute operates from -20°C to 80°C, compared to the original's -30°C to 85°C. Applications requiring operation below -20°C or above 80°C must identify alternative substitutes or confirm the substitute's suitability for the specific thermal environment.

Q: Why does the substitute have a different actuator type?

A: The original features a round button actuator while the substitute uses a plunger for cap design. Both provide On-Momentary switching function. The different actuator geometry may affect user interface feel and panel aesthetics but does not impact electrical switching behavior.

Q: Are both components RoHS compliant?

A: Yes. Both the MB2011LD1G01-CC and 1977737-2 are ROHS3 compliant, meeting environmental and hazardous substance restrictions for electronic components.

Q: What is the availability status of each component?

A: The MB2011LD1G01-CC is obsolete with no new production. The 1977737-2 is in active production, ensuring continued availability and supply chain reliability for new designs and maintenance applications.
