A pin-compatible GL5528 photoresistor from a different manufacturer with matching key electrical and physical specifications.
The GL5528 is a common 5mm light-dependent resistor (LDR) used for light detection. Finding a substitute involves matching its light/dark resistance, package, and spectral response. Several manufacturers produce parts under the same GL5528 model number.
Key parameters are very close.
Standard 5mm radial package is identical.
GL5528 is a widely multi-sourced component.
Direct replacement for GL5528(10-20) should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Cross-reference to other manufacturers' GL5528 series parts.
The primary risk is a mismatch in the light resistance tolerance or the gamma value, which can alter the circuit's sensitivity to light.
