A high-power functional alternative with superior electrical ratings, but requires board redesign for its SMB package.
CDBQC0130L-HF is a 30V, 100mA Schottky diode in a compact 0402C/SOD-923F package. While no direct pin-compatible replacements have been identified, several functional alternatives with superior electrical ratings are available but require a new PCB layout.
All candidates have different packages (SOD-123FL, SMB, SMC) than the target's 0402C/SOD-923F, requiring a new PCB layout.
All suggested alternatives meet or exceed the target's key voltage and current ratings.
No, a direct, pin-for-pin replacement for CDBQC0130L-HF was not found. All suitable electrical alternatives are in different physical packages.
Use a functional alternative like XBS104S14, which offers superior electrical ratings but requires a PCB layout change for its different package.
The primary risk is the package mismatch, which makes all candidates incompatible without a board redesign.

| Feature / factor | CDBQC0130L-HF | UMW SS510B | XBS104S14 | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 0402C/SOD-923F | SMB | SOD-123FL | SMB / SOD-123FL — Not a drop-in replacement; requires PCB layout change.; XBS104S14: Not a drop-in replacement; requires PCB layout change. | |
| Polarity Or Type | Schottky | Schottky | Schottky | Schottky — Functionally similar diode type.; XBS104S14: Functionally similar diode type. | |
| Voltage | 30V | 100V | 40V | 100V / 40V — Higher voltage rating provides more margin.; XBS104S14: Higher voltage rating provides more margin. | |
| Current | 0.1A | 5.0A | 1.0A | 5.0A / 1.0A — Significantly higher current handling.; XBS104S14: Significantly higher current handling. |
No direct drop-in replacement was found. The best functional alternative is likely XBS104S14, which has higher voltage (40V) and current (1A) ratings. However, it is in a different package (SOD-123FL) and requires a PCB redesign.
