Is there a pin-compatible replacement for 35TQC10MYF?

Currently, no fully verified pin-compatible replacement is listed. The Vishay 593D106X9035D2TE3 has a similar package but a much higher ESR, making it a risky substitute without circuit analysis.

What risks should I check before replacing 35TQC10MYF?

Key risks include: 1) Package mismatch requiring a new PCB layout. 2) Increased ESR if using solid tantalum, affecting filtering performance. 3) Capacitance loss due to DC bias if using an MLCC. 4) Different temperature ratings.

35TQC10MYF Alternatives, Datasheet & Cross Reference | PANASONIC

Reviewing alternatives for the Panasonic 35TQC10MYF, a 10µF 35V polymer tantalum capacitor. Substitutes often involve different capacitor technologies like solid tantalum or MLCCs, which require careful review of ESR, DC bias effects, and package footprint.

AI replacement insight

Package riskhigh

Most alternatives are MLCCs in different footprints, requiring a PCB redesign.

Electrical riskhigh

Key differences in ESR (for solid tantalum) and DC bias derating (for MLCCs) pose significant performance risks.

Sourcing riskmedium

Polymer tantalum capacitors can have a more constrained supply chain than standard MLCCs.

Can it be replaced directly?

No direct pin-to-pin replacement has been identified. The closest candidates have different electrical characteristics (higher ESR) or different packages (MLCCs) requiring a PCB redesign.

Best replacement path

Find another polymer tantalum capacitor with 10µF, ≥35V, ESR ≤ 120mΩ in a D2 (EIA 7343) package.

Main risk

Switching from polymer tantalum to MLCCs introduces significant DC bias derating, where effective capacitance drops under voltage. This can impact circuit performance.

Recommended alternatives

Functional alternative with matching voltage/capacitance but higher ESR and different tantalum technology. Package requires verification.
