Substitute Part Grouping Explanation

Substitute parts are classified into three categories based on electrical parameter modifications:

Voltage Upgrade Substitutes (KYOCERA AVX): Parts 1825HC472KAT1A and 1825HC472MAT1A increase the rated voltage from 2000V to 3000V while maintaining the same 4700 pF capacitance and 1825 package footprint. These upgrades are electrically compatible for applications requiring higher voltage margins. The 1825HC472KAT1A offers improved tolerance (±10% versus ±20%), while 1825HC472MAT1A maintains ±20% tolerance with different packaging (Tape & Reel).

Intermediate Voltage Substitute (KYOCERA AVX): Part 1825WC472KAT1A provides a 2500V (2.5kV) rated voltage with ±10% tolerance, positioning it between the original 2000V specification and the 3000V upgrades. This part maintains identical package dimensions and mechanical compatibility.

Manufacturer Alternative (KEMET): Part C1825C472MGRAC7800 from KEMET provides equivalent electrical specifications (4700 pF, ±20%, 2000V, X7R) with identical package footprint. This part features lower ESL characteristics and reduced thickness (0.061" versus 0.100"), enabling cross-manufacturer sourcing while maintaining form-factor compatibility.

All substitute parts share the following critical parameters with the main part: 4700 pF capacitance, X7R temperature coefficient, -55°C to 125°C operating range, 1825 package case, identical physical length and width, ROHS3 compliance, and MSL 1 rating.

Engineering Selection Recommendations

Direct Replacement (Identical Electrical Specifications): The KEMET C1825C472MGRAC7800 provides direct electrical equivalence to the 1825GC472MAT3A with matching 4700 pF capacitance, ±20% tolerance, and 2000V voltage rating. This part is suitable for applications where manufacturer diversification is required without circuit redesign. The reduced thickness profile (0.061" versus 0.100") may provide advantages in space-constrained PCB layouts.

Voltage Upgrade Path (KYOCERA AVX): The 1825HC472KAT1A and 1825HC472MAT1A offer increased voltage ratings (3000V) for applications requiring enhanced voltage safety margins. The 1825HC472KAT1A additionally provides tighter tolerance (±10%), beneficial for precision circuits. Both parts maintain identical footprint compatibility and ROHS3 compliance.

Intermediate Voltage Option (KYOCERA AVX): The 1825WC472KAT1A bridges the voltage gap at 2500V with ±10% tolerance, suitable for applications requiring voltage headroom between 2000V and 3000V specifications.

All substitute parts maintain active product status, ROHS3 compliance, unlimited moisture sensitivity rating, and identical operating temperature range (-55°C to 125°C), ensuring regulatory and environmental compatibility with the original specification.
