Is there a pin-compatible replacement for RTT013833FTH?

Currently, no pin-compatible (0201 package) replacement has been verified. All reviewed candidates have different physical packages and are not drop-in replacements.

What risks should I check before replacing RTT013833FTH?

The main risk is the package size; ensure your PCB layout can accommodate a larger component (e.g., 0603). Also, verify that any small deviation in resistance is within your circuit's tolerance.

RTT013833FTH Alternatives, Datasheet & Cross Reference | RALEC

Finding a substitute for the RALEC RTT013833FTH, a 383kΩ 1% 0201 chip resistor, requires careful attention to its small package. Alternatives often come in larger packages, necessitating PCB layout changes.

AI replacement insight

Package riskhigh

Target 0201 package is much smaller than candidates (0603), requiring board redesign.

Electrical risklow

Electrical parameters are either matched or improved, but some options have minor resistance deviation.

Can it be replaced directly?

No direct drop-in replacement has been identified. All candidates require review due to significant package size differences.

Best replacement path

Find another 0201 resistor with 383kΩ resistance. If unavailable, using a larger part like an 0603 is possible but requires a new board layout.

Main risk

The primary risk is the physical package mismatch. The target is a tiny 0201 package, while candidates are in much larger packages.

Recommended alternatives

Functionally similar 383kΩ resistor with higher power rating but in a larger 0603 package.
