Is there a pin-compatible replacement for GRM1555C1H750JA01D?

No, a direct pin-compatible replacement with identical key parameters was not found. The closest form-fit options, like GRM1555C1H680JA01D, have a different capacitance value (68pF vs 75pF) and require engineering review.

What risks should I check before replacing GRM1555C1H750JA01D?

Before replacing, you must check two main risks. First, if using an electrically identical part like GRM1885C1H750JA01D, you must verify your PCB can accommodate the larger 0603 package. Second, if using a form-fit part like GRM1555C1H680JA01D, you must verify your circuit's performance with the lower 68pF capacitance.

The Murata GRM1555C1H750JA01D is a 75pF, 50V, 0402 ceramic capacitor that is Not Recommended for New Designs (NRND). Finding a suitable replacement is critical for ongoing production. While no perfect drop-in exists, several functional and parametric alternatives are available for consideration.

AI replacement insight

Package riskhigh

One alternative has identical electricals but a larger 0603 package, requiring a board redesign.

Electrical riskmedium

Form-fit alternatives have ~9% lower capacitance, which may affect timing or filter circuits.

Sourcing riskmedium

The target and all close alternatives are marked NRND, indicating potential long-term supply issues.

Can it be replaced directly?

There is no direct, drop-in replacement for GRM1555C1H750JA01D among the candidates reviewed. All viable alternatives require either a PCB layout change or have different capacitance values that must be validated by an engineer.

Best replacement path

No direct drop-in found. For electrical parity, use GRM1885C1H750JA01D and redesign the PCB for the 0603 package. For a form-fit match, consider GRM1555C1H680JA01D but verify if the lower 68pF capacitance is acceptable.

Main risk

The primary risks are either mechanical (package mismatch) or electrical (capacitance difference), depending on the chosen alternative.

Recommended alternatives

A functional alternative with identical electrical specs but a larger 0603 package.
