A strong functional alternative in the same 0603 package with matching color, but may be slightly less bright.
Finding a substitute for the MHT192UBCT, a 0603 Brilliant Blue LED, involves matching its package, color, and electrical specs. While several options exist, careful review of luminous intensity and forward voltage is key to ensure performance.
Forward voltage and current of top candidates are compatible.
Candidates share the same standard 0603 package.
Multiple manufacturers produce similar 0603 blue LEDs, but specific brightness bins can vary.
No guaranteed drop-in replacement is confirmed. However, XL-1608UBC-04 is a strong candidate that requires verification of luminous intensity for the specific application.
XL-1608UBC-04 is the most promising alternative, matching key parameters with only a minor difference in brightness.
The primary risks are mismatched luminous intensity (brightness) and subtle color differences between manufacturers.

| Feature / factor | MHT192UBCT | XL-1608UBC-04 | MHT192WDT-ICE | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 0603 | 0603 | - | 0603 — Same standard 0603 package. | |
| Application | Brilliant Blue | Blue | - | Ice Blue — Color is 'Ice Blue', which may differ from 'Brilliant Blue'. | |
| Voltage | 2.7-3.3 V | 2.7-3.4 V | - | 3.1 V — Forward voltage is within target range. | |
| Luminous Intensity | 180-360 mcd | 120-270 mcd | - | 120-270 mcd — Candidate may be dimmer than the target. | |
| Lifecycle | Active | Active | - | Active — Both parts are active. | |
| Power | 60 mW | - | 95 mW | 95 mW — Higher power rating is acceptable. |
The best alternative identified is XL-1608UBC-04 by XINGLIGHT. It matches the package, color, and electrical specifications closely, but has a slightly lower maximum brightness which should be verified.
