A potential alternative with the same radial mounting style, but physical dimensions and tolerance differ.
Finding a substitute for the 178MU0024 radial capacitor requires careful review. While several functional alternatives exist, most are surface-mount (SMD) and require board redesign. Radial options may differ in size and tolerance.
Most candidates are SMD, requiring a board redesign. The one radial candidate has different dimensions.
All candidates have a wider tolerance (±20% vs. ±10%), which may impact performance in sensitive circuits.
No direct, drop-in replacement for 178MU0024 has been identified. All candidates have significant differences in package or electrical parameters that require engineering review.
The most promising path is SPZ1KM100E10O00RAXXX, as it is also a radial capacitor. However, its physical dimensions, lead spacing, and wider tolerance must be verified. All other candidates are SMD and require a board redesign.
The primary risk is package incompatibility. Most alternatives are surface-mount (SMD) and cannot replace the through-hole (Radial) target without a new PCB layout.

The most promising alternative is SPZ1KM100E10O00RAXXX, as it is also a radial (through-hole) capacitor. However, you must verify its physical size and lead spacing from the datasheet. It also has a wider tolerance (±20%). Other options are surface-mount (SMD) and would require a board redesign.
