Electrically superior SMD alternative in a slightly larger 4mm package.
Best Alternatives to TC33X-2-101E
The Bourns TC33X-2-101E is a 3mm single-turn SMD trimming potentiometer with 100 ohms resistance. Finding a replacement involves matching the 3mm footprint and key electrical parameters like power, tolerance, and TCR.
AI replacement insight
Package riskhigh
Many candidates have different footprints (4mm, TH) or unverified pinouts.
Electrical risklow
Several candidates offer superior power, tolerance, and TCR ratings.
Sourcing riskmedium
Some promising candidates are based on web discovery and may have unconfirmed data.
Can it be replaced directly?
Direct replacement for TC33X-2-101E should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
The most promising path is verifying the Murata PVG3A101C01R00, which appears to match the critical 3mm form factor and offers better performance. If its pinout is compatible, it's a strong candidate.
Main risk
The main risk is physical incompatibility. Several alternatives are electrically suitable but have different package sizes (e.g., 4mm) or mounting types (Through-Hole), requiring PCB layout changes.
