Is there a pin-compatible replacement for GRT188R6YA475KE13D?

No, there are no pin-compatible replacements in this analysis. All identified alternatives are in a larger package (0805) than the original's 0603 size, which means they will not fit on the same PCB footprint.

What risks should I check before replacing GRT188R6YA475KE13D?

Before replacing, you must verify three main risks: 1) Package size, as all alternatives are larger. 2) Application qualification, as some options lack the target's AEC-Q200 rating. 3) Dielectric characteristics if choosing a part with X7R or X7S instead of X5R.

GRT188R6YA475KE13D Alternatives, Datasheet & Cross Reference | Murata Manufacturing Co., Ltd.

Finding a replacement for the Murata GRT188R6YA475KE13D, a 4.7µF 35V 0603 AEC-Q200 capacitor, requires careful consideration of package size and qualification. No direct drop-in replacements have been identified.

AI replacement insight

Package riskhigh

All candidates have a larger package (0805 vs 0603), making them not drop-in compatible.

Sourcing riskmedium

Some alternatives are not AEC-Q200 qualified, which may be unacceptable for the original automotive application.

Electrical risklow

Key electrical parameters like capacitance and tolerance are matched. Voltage is matched or improved.

Can it be replaced directly?

No direct, pin-compatible replacement for GRT188R6YA475KE13D was found. All alternatives require a change in the PCB layout due to a larger package size.

Best replacement path

The best path is to use GRT21BR61H475KE13L, which requires a PCB redesign for the larger 0805 package but maintains the critical AEC-Q200 qualification.

Main risk

The primary risk is the physical package mismatch. All potential substitutes are in a larger 0805 case, while the original part is 0603.

Recommended alternatives

Functional alternative with higher voltage rating but in a larger 0805 package.
