Needs validationhigh risk
A functionally equivalent 5V 1.5A regulator with a wider temperature range, but in a surface-mount D2PAK package.
Best Alternatives to L7805CV-DG
The L7805CV-DG is a popular 5V, 1.5A positive voltage regulator in a TO-220 package. While direct pin-compatible replacements are common, alternatives often come in surface-mount packages requiring board redesign.
AI replacement insight
Package riskhigh
Candidates are SMD, target is through-hole, requiring PCB redesign.
Electrical risklow
Key electrical parameters (Vout, Iout) match on functional alternates.
Sourcing risklow
The 7805 family is widely available from multiple vendors.
Can it be replaced directly?
Direct replacement for L7805CV-DG should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
For new designs, consider L7805CDT-TR for a modern, surface-mount solution. For existing designs, seek another 7805-series regulator in a TO-220 package.
Main risk
The primary risk is the package mismatch, as all viable functional alternatives are surface-mount and not physically compatible with a TO-220 footprint.
