Engineering Selection Recommendations

Direct replacement (same voltage rating): C1812C474K2RAC7800 from KEMET is the only substitute maintaining the 200V rating. It offers improved tolerance (±10% vs ±20%) and reduced thickness (0.073" vs 0.098"), with Active product status and higher inventory availability (1501 units).

Voltage upgrade substitutes (250V rating): All remaining substitutes provide 250V rating, exceeding the original 200V specification. These are suitable for applications where higher voltage margin is beneficial:

KYOCERA AVX 1812PC474KAT1A and 1812PC474KAT2A: Active status, ±10% tolerance, reduced thickness (0.079"), with 1812PC474KAT2A offering significantly higher inventory (11460 units).
KEMET C1812C474JARAC7800: Active status, tightest tolerance (±5%), reduced thickness (0.073"), 1820 units available.
KEMET C1812C474KARAC7800: Active status, ±10% tolerance, reduced thickness (0.073"), highest inventory among 250V options (13162 units).
KEMET C1812C474MARAC7800: Active status, ±20% tolerance matching original, reduced thickness (0.073"), 3192 units available.
YAGEO CC1812KKX7RYBB474: Active status, ±10% tolerance, thinnest profile (0.071"), 2200 units available.
YAGEO CC1812MKX7RYBB474: Active status, ±20% tolerance matching original, thinnest profile (0.071"), 7033 units available.

Not recommended for new designs: TDK Corporation C4532X7R2E474K230KM and C4532X7R2E474M230KA carry "Not For New Designs" status and should be avoided for new applications despite meeting electrical specifications.

All recommended substitutes maintain ROHS3 compliance and MSL 1 rating.

Frequently Asked Questions (FAQ)

Q: Can I use a 250V rated capacitor in place of the 200V original? A: Yes. A higher voltage rating provides additional safety margin and is electrically compatible. The capacitor will function correctly in applications designed for 200V operation.

Q: What is the significance of tolerance differences (±20%, ±10%, ±5%)? A: Tolerance indicates the allowable deviation from the nominal 0.47 µF value. Tighter tolerances (±5%, ±10%) provide more precise capacitance values, beneficial for applications requiring strict capacitance specifications. The original ±20% tolerance is acceptable for general purpose applications where wider variation is tolerable.

Q: Are there physical space constraints I should consider? A: All substitutes maintain the same 1812 (4532 metric) package footprint (0.177" L x 0.126" W). However, thickness varies from 0.071" to 0.098". Verify PCB design accommodates the selected substitute's maximum thickness to avoid assembly issues.

Q: Why are some parts marked "Not For New Designs"? A: This status indicates the manufacturer is discontinuing the product line. While existing inventory may be available, these parts should not be selected for new designs to ensure long-term supply chain stability.

Q: Do all substitutes have the same moisture sensitivity level? A: Yes. All listed substitutes maintain MSL 1 (Unlimited), matching the original part's moisture handling requirements and storage conditions.

Q: Which substitute offers the best inventory availability? A: KYOCERA AVX 1812PC474KAT2A provides the highest inventory with 11460 units in stock, followed by KEMET C1812C474KARAC7800 with 13162 units. Both are Active status parts suitable for new designs.
