Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4105US-1 | Same electrical specs but in DO-213AA surface-mount package; no axial leads | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or high-vibration mechanical mounting | Select when automated assembly and board space constraints outweigh leaded-mounting advantages |
| JANTXV1N4105C-1 | Identical DO-35 package and electrical parameters; higher screening level (JANTXV vs JAN) | Required for programs mandating JANTXV qualification; not interchangeable without design review | Choose only when JANTXV-level burn-in, life test, and lot traceability are contractually required |
Compared with JAN1N4105C-1/TR, 1N4105US-1 offers footprint reduction at the cost of mechanical robustness, while JANTXV1N4105C-1 adds screening rigor without altering regulation performance - making the JAN version optimal for cost-sensitive, high-reliability through-hole deployments.
