Is there a pin-compatible replacement for CA45-D035K226T?

No, none of the reviewed candidates are pin-compatible. The target is a tantalum chip capacitor (7343-28), while candidates are can-type aluminum capacitors with different footprints, making them physically incompatible.

What risks should I check before replacing CA45-D035K226T?

Key risks are: 1) Package Mismatch: A board redesign is necessary. 2) Technology Change: Tantalum and Aluminum Electrolytic capacitors have different ESR, leakage current, and failure characteristics. 3) Parametric Downgrades: Candidates have wider tolerance (±20% vs ±10%) and lower max temperature (105°C vs 125°C).

CA45-D035K226T Alternatives, Datasheet & Cross Reference | Hunan Xiangyee Electronic Technology Co., Ltd.

CA45-D035K226T is a 22uF 35V solid tantalum capacitor. While no direct drop-in replacements have been identified, functional alternatives exist but require board redesign and careful engineering review due to differences in package and technology.

AI replacement insight

Package riskhigh

Candidate packages (SMD Can) are not compatible with the target's footprint (Tantalum Chip 7343-28). Board redesign is mandatory.

Electrical riskhigh

Change from Tantalum to Aluminum Electrolytic affects ESR, leakage, and reliability. Tolerance and temperature ratings are also weaker.

Can it be replaced directly?

There are no known direct, pin-compatible replacements for CA45-D035K226T among the candidates reviewed.

Best replacement path

No direct replacements were found. A board redesign is required to use functional alternatives like VZH220M1HTR-0606L, which use a different package and capacitor technology.

Main risk

The primary risk is the physical and electrical mismatch. The package is different, requiring a new PCB layout, and the change from Tantalum to Aluminum Electrolytic technology affects performance.

Recommended alternatives

Functional alternative with same capacitance but requires board redesign due to different package and capacitor technology.
