KNH2100UF50V149EC0019 is a 100uF 50V through-hole aluminum capacitor. While functional alternatives exist, no direct drop-in replacements have been found, as all candidates have a different (SMD) package type requiring board redesign.

AI replacement insight

Package riskhigh

Target is Through-Hole, candidates are SMD. Requires board redesign.

Electrical riskmedium

Secondary parameters like ESR, ripple current, and lifetime must be verified.

Sourcing risklow

Candidates are from a major manufacturer (Lelon) and appear to be active.

Can it be replaced directly?

No direct, pin-compatible replacements have been identified. All current candidates are Surface Mount (SMD) devices and require a board redesign to replace the through-hole target.

Best replacement path

Search for a 100uF, 50V (or higher) aluminum electrolytic capacitor in a through-hole radial package with dimensions near 8mm x 9mm and similar or better ESR and ripple current ratings.

Main risk

Package risk is high. The target is a through-hole component, while all potential alternatives are surface-mount, making them physically incompatible without a new PCB layout.
