Strong functional upgrade with higher voltage and current ratings, but in a different, through-hole package.
The L7805CV-HXY is a common 5V, 1A linear voltage regulator in a TO-220S package. While no direct pin-compatible replacements were found in this package, several functional alternatives exist in different packages like TO-220, DPAK, and SOT-223.
No candidates match the TO-220S package; PCB redesign is mandatory.
Some candidates have lower input voltage or narrower temperature ranges that must be verified.
The 7805 regulator family is widely available from many manufacturers.
There is no direct, drop-in replacement for L7805CV-HXY in the same TO-220S package among the candidates reviewed. All require design changes.
For through-hole designs, L7805CV(XBLW) is a strong functional upgrade. For surface-mount, LR7805D is a close electrical match. Both require PCB redesign.
The primary risk is the package mismatch, as no alternatives share the TO-220S footprint, necessitating a PCB redesign.

| Feature / factor | L7805CV-HXY | L7805CV(XBLW) | LM7805 | LM7805CTG | Compatibility / risk |
|---|---|---|---|---|---|
| Package | TO-220S | TO-220 | TO-263 | TO-220-3 | TO-220 / TO-263 / TO-220-3 / DPAK (TO-252) — Through-hole package, not SMT. Not a direct fit.; LM7805: Different SMT footprint (D2PAK), not a direct fit.; LM7805CTG: Through-hole package, not SMT. Not a direct fit.; LR7805D: Different SMT footprint, not a direct fit. |
| Voltage | 35V | 40V | 35V | 35V | 40V / 35V — Higher max input voltage is a safe upgrade.; LM7805: Max input voltage matches.; LM7805CTG: Max input voltage matches.; LR7805D: Max input voltage matches. |
| Current | 1.0A | 1.5A | 1.0A | 1.5A | 1.5A / 1.0A — Higher output current is a safe upgrade.; LM7805: Output current matches.; LM7805CTG: Higher output current is a safe upgrade.; LR7805D: Output current matches. |
| Temperature | -25°C to 125°C | -20°C to 125°C | 0°C to 125°C | 0°C to 125°C | -20°C to 125°C / 0°C to 150°C — Slightly narrower operating range at low end.; LM7805: Reduced operating range, not suitable for sub-zero use.; LM7805CTG: Reduced operating range, not suitable for sub-zero use.; LR7805D: Reduced operating range, not suitable for sub-zero use. |
The best alternative depends on your application's constraints. L7805CV(XBLW) offers upgraded current and voltage ratings in a TO-220 package. If a surface-mount solution is needed, LR7805D in a DPAK package is a strong electrical match, but both require board layout changes and have different temperature ranges.
