Excellent upgrade path with identical key specs and improved Q-factor from the same manufacturer.
Find recommended substitutes for the Murata GRM1555C1H5R1BA01D, a 5.1pF 50V 0402 MLCC. As this part is Not Recommended for New Designs (NRND), we provide verified upgrade paths and functional alternatives.
Key parameters match or are improved on the top candidate. Looser tolerance on cross-vendor options requires review.
All viable candidates share the same 0402 package, ensuring form-fit compatibility.
The target is NRND; all proposed alternatives are active, improving availability.
Yes, GJM1555C1H5R1BB01D is a direct, pin-compatible replacement for GRM1555C1H5R1BA01D with identical ratings and an improved Q-factor.
The best replacement is GJM1555C1H5R1BB01D, an upgrade path from the same manufacturer with identical key specs and an active lifecycle.
The main risk when substituting is ensuring parametric differences, such as tolerance or series characteristics (e.g., Q-factor), are acceptable for the application.
