Potential upgrade from the same manufacturer with better capacitance; requires power rating verification.
NUP4202W1T2G is a 4-channel TVS diode array for high-speed line protection. When searching for alternatives, prioritize matching the SC-88 package, 4-channel configuration, and 500W peak power rating.
Substitutes may have lower surge power/current ratings, compromising protection.
The SC-88/SOT-363 package is standard, but pinout must always be confirmed.
No verified direct drop-in replacement has been identified. NUP4114UCLW1T2G is a strong candidate but requires engineering review of its power rating. Other parts like NUP2202W1T2G have fewer channels and are not compatible.
NUP4114UCLW1T2G from the same manufacturer offers upgraded performance but requires verification of its peak power rating for your specific surge requirements.
The primary risk is mismatched surge protection capability. A replacement must handle the same peak pulse power (500W) and current to avoid circuit damage.

|---|---|---|---|---|---|
| Package | SC-88 (SOT-363) | SC-88 (SOT-363) | SC-88, SOT-363 | SC-88 (SOT-363) / SC-88, SOT-363 — Same package family ensures form factor compatibility.; IP4233CZ6,125: Same package family ensures form factor compatibility. | |
| Channels | 4 | 4 | 4 | 4 — Matches the 4-channel protection configuration.; IP4233CZ6,125: Matches the 4-channel protection configuration. | |
| Voltage | 5V | 5.5V | 5.5V | 5.5V — Slightly higher working voltage is acceptable.; IP4233CZ6,125: Working voltage is compatible. | |
| Capacitance | 1.5 pF | 0.6 pF | - | 0.6 pF — Lower capacitance is better for high-speed signals. | |
| Power | 500W | Missing | - | Missing — Peak power rating (Ppk) must be verified to be >= 500W. | |
| Current | 5A (Ipp) | - | 3A (Ippm) | 3A (Ippm) — Lower peak pulse current suggests lower surge capability. |
NUP4114UCLW1T2G by onsemi is a promising upgrade with better capacitance, but its peak power rating must be confirmed to match the target's 500W capability before use.
