Engineering Selection Recommendations

Same Voltage Rating (1500V): 1808SC102KAT1A is a direct substitute with tighter ±10% tolerance and identical physical dimensions. Both parts are KYOCERA AVX products with active production status and ROHS3 compliance.

Voltage Upgrade to 2000V: 1808GC102MAT1A and 1808GC102KAT1A maintain the same physical footprint (0.071" thickness) as the original part. The KGM42CR73D102KY and KGM42CR73D102MY from the KGM-HV series offer increased thickness (0.087") with higher current handling capability. C1808C102KGRAC7800 (KEMET) and C4520X7R3D102K130KA (TDK) provide cross-manufacturer alternatives with 2000V rating and ROHS3 compliance.

Voltage Upgrade to 2500V: 1808WC102KAT1A increases thickness to 0.087" and is available in higher inventory quantities.

Voltage Upgrade to 3000V: 1808HC102KAT1A and KGM42CR73U102KY both provide 3000V rating with 0.087" thickness. KGM42CR73U102KY is from the KGM-HV series with higher inventory availability (5700 units).

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and -55°C to 125°C operating temperature range. Selection should account for physical space constraints (thickness variation), tolerance requirements, and voltage margin requirements for the application.

Frequently Asked Questions (FAQ)

Q: Can 1808SC102KAT1A replace 1808SC102MATME directly? A: Yes. Both parts share identical capacitance (1000 pF), voltage rating (1500V), package (1808), and temperature coefficient (X7R). The substitute has tighter tolerance (±10% vs ±20%) and higher inventory availability (5443 vs 1078 units).

Q: What is the difference between KYOCERA AVX standard series and KGM-HV series? A: The KGM-HV series parts (KGM42CR73D102KY, KGM42CR73D102MY, KGM42CR73U102KY) feature increased thickness (0.087" vs 0.071") for enhanced voltage handling and thermal performance. Both series maintain identical capacitance, temperature coefficient, and compliance specifications.

Q: Can I use a 2000V rated part in place of the 1500V original? A: Yes, provided all other electrical parameters match (capacitance, tolerance, temperature coefficient, package). Higher voltage ratings provide additional safety margin and are electrically compatible with 1500V applications. Physical dimensions may vary; verify thickness compatibility with PCB layout constraints.

Q: Are KEMET and TDK alternatives fully compatible? A: KEMET C1808C102KGRAC7800 and TDK C4520X7R3D102K130KA are electrically equivalent with matching capacitance, tolerance, voltage, and temperature coefficient. Both are ROHS3 compliant with MSL 1 rating. Physical dimensions differ slightly; verify footprint compatibility before substitution.

Q: What does MSL 1 rating mean for this capacitor? A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture baking requirements. The part can be stored and handled without special moisture control procedures.

Q: Why do some substitute parts have different thickness values? A: Thickness variation (0.059" to 0.087") reflects different internal electrode configurations and voltage rating designs. Higher voltage ratings typically require thicker dielectric layers. Verify PCB assembly clearance before selecting parts with increased thickness.
