Procurement Notes

Verify the specific ordering suffix 'G' indicates a Pb-Free package configuration as documented in the datasheet. Confirm the package style matches the required TO-92 form factor for your assembly process. Ensure that the standard 10% capacitance tolerance aligns with your circuit design requirements before finalizing procurement.

Selection Notes

Select this component when a 30 Vdc reverse voltage rating and approximately 33 pF nominal capacitance are required. Consider the TO-92 through-hole package if surface mount options are not feasible. Evaluate the 200 mAdc forward current limit against peak circuit demands. Verify compatibility with high-volume production needs due to its design focus on solid-state reliability.

Part Context

The MV2109G belongs to the MMBV2101LT1 series, which includes variants like MV2101, MV2105, and LV2209. These devices share similar electrical characteristics but differ in capacitance ranges and package types. The series is engineered for high-volume manufacturing in plastic packages, providing a standardized solution for frequency control tasks across consumer electronics.

Replacement Considerations

Direct substitutes within the same series include MV2101, MV2105, and LV2209, provided their specific capacitance values match the design requirements. Surface-mount equivalents such as MMBV2109LT1 offer identical electrical performance in a SOT-23 package.
