Specs side by side
2 parts compared · 18 differing specs across 18 total parameters.
| Parameter | ||
|---|---|---|
| Operating temperature | -65°C ~ 200°C | - |
| Supply voltage | - | Identical electricals across the through-hole and MELF rows. |
| Voltage - Zener (nom) | 5.1 V | - |
| Memory & Peripherals | - | The choice is mechanical: a machine-placeable cylinder against a wire-lead axial - the repair follows the board footprint. |
| Case | DO-204AL, DO-41, Axial | DO-213AB (MELF, SMD) |
| Package | Bulk | - |
| Compatibility Level | - | Functional Equivalent |
| Core & Architecture | - | The surface-mount form of the same family: the same 1W 5.1V grade in the MELF body, for boards built after the through-hole era and for rework on them. |
| Current - Reverse Leakage @ Vr | 10 µA @ 1 V | - |
| Firmware Notes | - | When substituting toward the axial part (MELF unavailable), the lead forming radius and the board clearance are the only open items - the electricity does not change. |
| Hardware Notes | - | DO-213AB MELF footprint; the axial DO-41 does not fit it and the reverse needs lead forming. |
| Impedance (max) | 7 Ohms | - |
| Lead Time Advantage | - | Shenzhen Spot Stock (24-48h Dispatch) |
| Mounting | Through Hole | - |
| Power - Max | 1 W | - |
| Reference Part | - | 1N4733A |
| Sourcing Advantage | - | Stocked in both forms; state the footprint when quoting. |
| Tolerance | ±5% | - |
