Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Fixed Parameters (Must Match):

• Capacitance: 470 pF
• Package / Case: 1812 (4532 Metric)
• Mounting Type: Surface Mount, MLCC
• Operating Temperature Range: -55°C ~ 125°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variations:

• Voltage Rating: Equal to or greater than 1500V
• Tolerance: Equal to or tighter than ±20%
• Temperature Coefficient: X7R or C0G/NP0

All four substitute parts meet these criteria. Three parts (1812GA471JAT1A, 1812GC471KAT1A, 1812HC471KAT1A) are direct KYOCERA AVX equivalents with improved specifications. The fourth part (KGM43ER73U471KV) is from the KYOCERA AVX KGM - HV series, also meeting all substitution requirements.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts are active products with ROHS3 compliance and REACH unaffected status, matching the original component's regulatory standing.

1812GA471JAT1A provides upgraded voltage rating (2000V) and superior tolerance (±5%) with C0G/NP0 temperature coefficient, offering enhanced stability. Thickness increases to 0.087" (2.20mm), requiring PCB layout verification.

1812GC471KAT1A maintains X7R temperature coefficient while upgrading voltage to 2000V and tolerance to ±10%, with identical thickness to the original part. This represents a direct performance upgrade with minimal design impact.

1812HC471KAT1A and KGM43ER73U471KV both provide 3000V rating with ±10% tolerance and X7R coefficient. Both maintain original thickness of 0.071" (1.80mm). The KGM43ER73U471KV is from the KGM - HV series with higher inventory availability (8662 vs 1135 units).

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with higher voltage rating? A: Yes. Higher voltage ratings are acceptable substitutes as they provide greater safety margin. All listed substitutes with 2000V or 3000V ratings are compatible with the original 1500V application.

Q: What is the difference between X7R and C0G/NP0 temperature coefficients? A: X7R provides ±15% capacitance change across the operating temperature range. C0G/NP0 provides superior stability with ±0.3% change. C0G/NP0 is suitable where temperature stability is critical.

Q: Does the increased thickness of 1812GA471JAT1A affect PCB compatibility? A: The thickness increase from 0.071" (1.80mm) to 0.087" (2.20mm) requires verification of available PCB clearance and component placement constraints. Other substitutes maintain the original 0.071" (1.80mm) thickness.

Q: Are all substitutes available in the same packaging format? A: The original part is available in Cut Tape (CT) & Digi-Reel® packaging. Substitutes 1812GC471KAT1A, 1812HC471KAT1A, and KGM43ER73U471KV are supplied in Tape & Reel (TR) format. 1812GA471JAT1A is available in both CT and TR formats.

Q: Which substitute offers the best tolerance specification? A: 1812GA471JAT1A provides ±5% tolerance, the tightest specification among all options. Other substitutes offer ±10% tolerance, compared to the original ±20%.
