A 3mm green LED with different electrical and optical properties requiring careful engineering review.
MHK1375CGBTD is a 3mm green diffused LED with a 2.2V forward voltage and wide 80° viewing angle. Finding a substitute requires careful matching of these key electrical and optical parameters.
Candidate forward voltage (3.0V) is much higher than target (2.2V).
Candidates share the same 3mm through-hole package.
Finding a 2.2V green LED may require searching older component families.
No direct drop-in replacements were found. All reviewed candidates have significant differences in forward voltage and viewing angle.
Search for a 3mm (T-1) green LED with a forward voltage near 2.2V and a wide viewing angle (~80°).
The primary risk is electrical incompatibility due to higher forward voltage (e.g., 3.0V vs 2.2V), which may prevent the LED from lighting up or cause premature failure.
