Murata Electronics
A form-fit compatible choke, but with much lower current/voltage ratings and different inductance requiring full design validation.
DLW32SH510XK2L is a 51µH, 200mA AEC-Q200 common mode choke from Murata in a 1210 package. Finding a suitable replacement requires carefully matching its relatively high current and voltage ratings for its size.
Candidates have much lower current/voltage ratings and different inductance, requiring complete circuit re-evaluation.
Several alternatives exist in the same 1210 4-pin package, but pinout function must be confirmed.
No direct, drop-in replacement is currently identified. All candidates found have significant electrical downgrades in current and voltage.
Search for AEC-Q200 common mode chokes in a 1210 package with ≥51µH inductance, ≥200mA current, and ≥80V voltage.
The primary risk is substituting with a part that has a lower current rating, which could lead to component overheating, failure, and system malfunction.

| Feature / factor | DLW32SH510XK2L | DLW32MH101XK2L | DLW32MH101XT2L | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 1210 (3225 metric) | 1210 (3225 metric) | 1210 (3225 metric) | 1210 (3225 metric) — Form factor is compatible.; DLW32MH101XT2L: Form factor is compatible. | |
| Current | 200 mA | 100 mA | 100 mA | 100 mA — Candidate current rating is 50% lower.; DLW32MH101XT2L: Candidate current rating is 50% lower. | |
| Voltage | 80 VDC | 50 V | 50 V | 50 V — Candidate voltage rating is significantly lower.; DLW32MH101XT2L: Candidate voltage rating is significantly lower. | |
| Inductance | 51 uH | 100 µH | 100 µH | 100 µH — Significantly higher inductance will alter filter characteristics.; DLW32MH101XT2L: Significantly higher inductance. | |
| Dcr | 0.7 Ohm max | 2.8 Ω | - | 2.8 Ω — Higher DCR increases power loss. |
Currently, no direct drop-in replacements have been identified. Alternatives like the Murata DLW32MH series have the same package but significantly lower current and voltage ratings, requiring careful circuit analysis before use.
