Shares the same package and voltage, but emits red light, making it a functional alternative only.
MHL5013GTD is a 5mm yellow-green through-hole LED. While no direct replacements have been identified, several functional alternatives in the same package with different colors are available from the same manufacturer.
Some alternatives have different forward voltages, requiring circuit changes.
Kept alternatives share the same 5mm through-hole package.
No direct, drop-in replacement for MHL5013GTD has been confirmed. All reviewed candidates have functional differences, primarily in emitted color.
Consider other 5mm T-1 3/4 LEDs from the MEIHUA MHL5013 series if color is flexible. Verify forward voltage and luminous intensity.
The primary risk is functional mismatch due to different emitted colors and, in some cases, different forward voltages.

| Feature / factor | MHL5013GTD | MHL5013URDRT | MHL5013UYDYT | MHL5013UGDGT | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 5mm Round (Through-Hole) | 5mm Round (T-1 3/4) | 5mm Round | 5mm Round (T-1 3/4) | 5mm Round (T-1 3/4) — Package is form-fit compatible.; MHL5013UYDYT: Package is form-fit compatible.; MHL5013UGDGT: Package is form-fit compatible. |
| Application | 26.6 mcd | 550 mcd | Yellow Diffused | 1820 mcd | 550 mcd / Yellow Diffused / 1820 mcd — Significantly higher luminous intensity.; MHL5013UYDYT: Lens color is different.; MHL5013UGDGT: Significantly higher luminous intensity. |
| Voltage | 2.2V | 2.2V | 2.2V | 3.2V | 2.2V / 3.2V — Forward voltage matches.; MHL5013UYDYT: Forward voltage matches.; MHL5013UGDGT: Higher forward voltage requires series resistor change. |
MHL5013UYDYT is a close parametric match but emits yellow light (590nm) instead of yellow-green (570nm). If color is flexible, it's a strong candidate. Otherwise, review is required.
