Electrically similar X2 cap from the same series, but with different lead spacing (10mm vs 15mm) requiring board layout changes.
Finding a substitute for the SRD MP2104K27D2X8LC X2 safety capacitor requires careful attention to its 15mm lead spacing. While electrically similar parts exist, mechanical compatibility is the primary challenge.
Lead spacing mismatch (15mm vs 10mm) prevents drop-in replacement and requires PCB modification.
If a part with matching electrical specs is found, electrical risk is minimal.
No direct, pin-for-pin replacement is currently identified due to a mismatch in lead spacing with available candidates.

| Feature / factor | MP2104K27D2X8LC | MP2104K27C3X6LC | MP1104K44C3R6LC | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Capacitance | 0.1 µF | 0.1 µF | - | 0.1 µF — Identical capacitance. | |
| Voltage | 275 VAC | 275 VAC | - | 440 VAC — Higher voltage rating is a safe upgrade. | |
| Application | X2 | X2 | - | X1 — X1 class is an upgrade over X2. | |
| Package | 15 mm | 10 mm | - | 10 mm — Lead spacing mismatch prevents drop-in. |
The best alternative depends on your ability to modify the PCB. MP2104K27C3X6LC is electrically identical but has 10mm lead spacing. If a higher voltage rating is acceptable, MP1104K44C3R6LC is an option, but also has 10mm spacing.
