Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2011SD3G01-CF is determined by the following critical parameters:

• Circuit configuration must be SPDT
• Switch function must be On-Momentary
• Mounting type must be Panel Mount, Rear
• Termination style must be Solder Lug
• Voltage rating must meet or exceed 28V DC
• Current rating must accommodate 0.4VA or equivalent
• Electrical life must be rated for minimum 50,000 cycles
• RoHS3 compliance required

The substitute part 1977737-2 from TE Connectivity ALCOSWITCH Switches meets these core functional and electrical requirements, though with specific parameter variations noted in the comparison table below.

Engineering Selection Recommendations

The 1977737-2 substitute part is suitable for applications where the MB2011SD3G01-CF is no longer available. Both parts maintain ROHS3 compliance and equivalent electrical life ratings of 50,000 cycles.

Key considerations for selection:

The substitute part operates at 60mA DC current rating, which is lower than the 0.4VA rating of the main part. Verify that your application current requirements do not exceed 60mA DC.

The substitute part voltage rating is 30V DC, which exceeds the 28V requirement of the main part and provides adequate margin.

The substitute part operating temperature range is -20°C to 80°C, compared to the main part range of -30°C to 85°C. Confirm that your application operating environment falls within this narrower range.

Both parts feature identical circuit configuration (SPDT), switch function (On-Momentary), mounting type (Panel Mount, Rear), and termination style (Solder Lug), ensuring mechanical and electrical compatibility in the circuit.

The substitute part is currently in active production status with 1048 units in stock, providing supply continuity compared to the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can the 1977737-2 directly replace the MB2011SD3G01-CF in my application?

A: Direct replacement is possible if your application current requirement does not exceed 60mA DC and your operating temperature range remains within -20°C to 80°C. Both parts share identical circuit configuration, switch function, mounting type, and termination style. Verify these parameters against your system specifications before implementation.

Q: What is the primary difference between these two parts?

A: The main difference is the current rating. The MB2011SD3G01-CF is rated for 0.4VA (AC/DC), while the 1977737-2 is rated for 60mA DC. The substitute part also has a slightly narrower operating temperature range (-20°C to 80°C versus -30°C to 85°C) and a higher voltage rating (30V DC versus 28V DC).

Q: Are both parts RoHS compliant?

A: Yes, both the MB2011SD3G01-CF and 1977737-2 are ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: What packaging is available for the substitute part?

A: The 1977737-2 is supplied in bulk packaging, with 1048 units currently in stock.

Q: Do both parts have the same electrical life rating?

A: Yes, both parts are rated for 50,000 electrical cycles, ensuring equivalent operational durability in switching applications.

Q: What is the panel cutout dimension for the substitute part?

A: The panel cutout dimension for the 1977737-2 is not specified in the available technical data. Confirm mechanical compatibility with your panel installation requirements before proceeding with substitution.
