Is there a pin-compatible replacement for GRM1555C1H621GA01D?

Yes, GCM1555C1H621JA16D is a pin-compatible replacement in the same 0402 package. However, its electrical tolerance is wider (±5% vs ±2%), so it's not an exact drop-in.

What risks should I check before replacing GRM1555C1H621GA01D?

Verify the substitute's capacitance tolerance (target is ±2%) and ensure the dielectric is C0G/NP0. Using a different dielectric like X7R or a part with incorrect capacitance can impact circuit performance.

AI replacement insight

Electrical riskmedium

Substitutes may have different tolerance or capacitance, requiring circuit validation.

Package risklow

Many 0402 package alternatives are available.

Sourcing risklow

The target is NRND, but similar C0G capacitors are widely available.

Can it be replaced directly?

No exact direct replacement is identified. GCM1555C1H621JA16D matches key parameters but has a wider tolerance (±5% vs ±2%).

Best replacement path

The best replacement path is to find a capacitor with the same 620pF capacitance, C0G dielectric, and 0402 package. GCM1555C1H621JA16D is a strong candidate if a wider ±5% tolerance is acceptable.

Main risk

The main risk is parameter mismatch. Using a capacitor with different capacitance, tolerance, or dielectric (e.g., X7R) can cause circuit failure.

Recommended alternatives

Automotive-grade alternate with same capacitance and voltage but wider tolerance (±5%).
