Best Alternatives to CA45-D-16V-100uF-K
CA45-D-16V-100uF-K is a D-case 100uF 16V tantalum capacitor. No reviewed candidate is confirmed pin-compatible from the available fields.
AI replacement insight
Electrical riskhigh
Voltage, tolerance, ESR, and capacitance must be checked.
Package riskhigh
Most candidates are not proven D (7343).
Firmware risklow
Passive capacitor; no firmware impact expected.
Sourcing riskmedium
Target lifecycle and supply status are not resolved.
Can it be replaced directly?
Direct replacement for CA45-D-16V-100uF-K should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
Start with a D-case 100uF 16V or higher tantalum part with ±10% and +125°C ratings.
Main risk
Package and voltage rating are the main blockers.
