A strong upgrade with a higher 630V rating and an equivalent NP0 dielectric in the same 1206 package.
Reviewing alternatives for the TDK C3216C0G2E682JT000N, a 6.8nF 250V C0G capacitor. Key considerations for substitutes are maintaining the stable C0G/NP0 dielectric and matching capacitance.
High risk if substituting with a different dielectric (e.g., X7R) or incorrect capacitance value.
All viable candidates share the same 1206 package, minimizing physical compatibility issues.
While no exact drop-in is listed, CGA5H4NP02J682JT0Y0N is a functionally equivalent upgrade with a higher voltage rating and is considered pin-compatible.
The TDK CGA5H4NP02J682JT0Y0N is a strong upgrade path, offering a higher 630V rating with an equivalent NP0 dielectric.
The main risk is substituting with a different dielectric type, like X7R, which has poor stability compared to the target's C0G.
