Is there a pin-compatible replacement for TC33X-2-201E?

No direct pin-compatible replacement was identified in this review. Alternatives like 3314J-1-201E have different package sizes and footprints, requiring board modification.

What risks should I check before replacing TC33X-2-201E?

The main risk is mechanical incompatibility. Verify the package dimensions and PCB footprint of any alternative. Also, confirm that improved electricals like higher power or multi-turn adjustment (e.g., 3224W-1-201E) are acceptable for your application.

TC33X-2-201E Alternatives, Datasheet & Cross Reference | BOURNS

The Bourns TC33X-2-201E is a 200-ohm single-turn SMD trimmer in a compact 3mm package. While no direct pin-compatible replacements were found, several functional alternatives with superior electrical characteristics are available but require board redesign.

AI replacement insight

Package riskhigh

Candidates are in a 4mm package, target is 3mm. Footprint is different.

Electrical risklow

Candidates offer superior power, tolerance, and TCR ratings.

Can it be replaced directly?

No direct, drop-in replacement for TC33X-2-201E was found. All viable candidates have a different mechanical package.

Best replacement path

Use Bourns 3314J-1-201E for a single-turn functional upgrade or 3224W-1-201E for a multi-turn precision upgrade, but plan for a PCB respin for the larger 4mm package.

Main risk

Package and footprint mismatch is the primary risk, preventing a direct drop-in replacement.

Recommended alternatives

A functional alternative with superior electricals (power, tolerance, TCR) but requires board layout changes due to its larger 4mm package.
