Same package and voltage, but with a lower capacitance of 1.5pF that requires engineering review.
Best Alternatives to GJM1555C1H3R0BB01D
GJM1555C1H3R0BB01D is a high-Q 3pF 50V C0G ceramic capacitor in an 0402 package, ideal for RF and microwave circuits. Finding a direct drop-in replacement is challenging due to the criticality of its capacitance value.
AI replacement insight
Electrical riskhigh
Capacitance mismatch in RF circuits can shift frequencies or cause impedance mismatches.
Package riskhigh
The electrically identical alternate is in a smaller 0201 package, which is not a drop-in replacement for 0402.
Can it be replaced directly?
No direct, pin-compatible replacement with identical key parameters was found. All form-fit candidates have different capacitance values.
Best replacement path
For new designs or board revisions, GRM0335C1H3R0BA01D is an electrically identical option in a smaller 0201 package. For existing 0402 layouts, several same-series parts exist but all have different capacitance values, requiring careful circuit analysis.
Main risk
The primary risk is performance deviation due to either capacitance mismatch (for same-package parts) or package mismatch requiring a new PCB layout.

Questions & answers
The best alternative depends on your design constraints. GRM0335C1H3R0BA01D is electrically identical but in a smaller 0201 package. If you must maintain the 0402 package, several GJM series parts are available but have different capacitance values (e.g., 1.8pF, 4.7pF, 5.6pF) and require circuit validation.
