Functional alternative with same capacitance but requires review due to different package, technology, and electricals.
Finding a replacement for the CA45-D010K337T, a 330µF 10V Tantalum capacitor, requires careful review. While alternatives with similar capacitance exist, they often differ in technology, package, and key electrical parameters, necessitating board-level changes.
Candidates have different footprints (V-Chip vs. Tantalum D-Case), requiring board redesign.
Different technology (Al-Elec vs. Tantalum), wider tolerance, and lower temperature rating.
While candidates are active, finding a true Tantalum equivalent may be challenging.
No direct, pin-compatible replacement has been identified. All candidates are Aluminum Electrolytic capacitors in different packages, requiring board redesign and careful electrical evaluation.
Search for Tantalum capacitors with 330µF capacitance, ≥10V rating, and a 7343-28 (D-Case) package.
The primary risk is the package and technology mismatch. Using an Aluminum Electrolytic V-Chip capacitor requires a new PCB layout and validation of electrical performance (ESR, leakage, temperature stability).
