A form-fit-function alternative in an 0805 package with matching capacitance, tolerance, and C0G dielectric.
Finding a substitute for the TORCH CC4-0805-CG-100V-100PF-J involves matching its 100pF, 100V, ±5%, C0G dielectric, and 0805 package. Alternatives exist with identical or better electricals, but package size is a key factor.
Many candidates have different packages (1206, 0603, Disc) requiring PCB changes.
Key electricals (capacitance, C0G dielectric) are common and easy to match.
Yes, parts like HRE's CGA0805C0G101J101HT offer a very close match in the same 0805 package, requiring minimal design review.
The best path is finding a capacitor with an 0805 package, 100pF capacitance, C0G/NP0 dielectric, and a voltage rating of 100V or higher.
The main risk is package mismatch. Several candidates are functionally similar but come in different SMD sizes or through-hole packages.
