Cross Reference MLCC vs. VISHAY Tantalum DATA SHEET
●Attached is a list of the MLCCs which are in short supply.
In crossing these parts, the first goal is to offer a polymer alternative to MLCC. If polymer is not available, then we can offer a standard tantalum.
●The assumptions are as follows:
■we matched capacitance. Depending on application, user may be able to use lower value tantalum due to VCC and TCC which lower effective capacitance of MLCC
■we matched voltage rating. For polymer tantalum, it is ok. For standard tantalum, engineer should verify that application voltage meets 50 % derating guideline
■we did not consider ESR or DCL since these performance parameters are significantly different for each capacitor type and should be checked relative to the needs of the application
