1812SC471MAT3A Equivalent & Substitute Parts

Part Overview

The 1812SC471MAT3A is a 470 pF ceramic capacitor rated at 1500V (1.5kV) with X7R temperature coefficient, manufactured by KYOCERA AVX in 1812 (4532 Metric) surface mount package. This high-voltage MLCC is designed for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is active, ROHS3 compliant, and carries MSL 1 rating for unlimited moisture sensitivity protection. Equivalent and substitute parts are identified based on matching capacitance value, package form factor, and compatible electrical ratings that allow direct circuit substitution.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1812SC471MAT3A is determined by the following criteria:

Primary Matching Parameters:

• Capacitance value: 470 pF (exact match required)
• Package form factor: 1812 (4532 Metric) surface mount
• Operating temperature range: -55°C to 125°C (minimum requirement)
• Mounting type: Surface Mount, MLCC

Allowable Variation Parameters:

• Voltage rating: Equal to or greater than 1500V
• Temperature coefficient: X7R or C0G/NP0 (both acceptable for general-purpose applications)
• Tolerance: ±20% or tighter (±10%, ±5%)

All identified substitute parts maintain the same 1812 package footprint and physical dimensions (0.181" L x 0.126" W), ensuring direct PCB compatibility. Substitute parts with higher voltage ratings provide enhanced design margin. Parts with tighter tolerance specifications or alternative temperature coefficients offer improved performance characteristics while maintaining functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active products manufactured by KYOCERA AVX with ROHS3 compliance and MSL 1 rating, meeting the same environmental and regulatory requirements as the primary part.

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

1812GC471KAT1A maintains X7R temperature coefficient matching the original part while providing 2000V voltage rating and ±10% tolerance. Thickness remains at 0.071" (1.80mm), ensuring direct physical compatibility without layout modifications.

1812HC471KAT1A and KGM43ER73U471KV both deliver 3000V voltage rating with X7R temperature coefficient and ±10% tolerance. Both maintain 0.071" (1.80mm) thickness for direct footprint compatibility. KGM43ER73U471KV is designated as part of the KGM - HV series for high-voltage applications.

Frequently Asked Questions (FAQ)

Q: Can I substitute 1812SC471MAT3A with a higher voltage-rated part?

A: Yes. All substitute parts with voltage ratings equal to or greater than 1500V are electrically compatible. Higher voltage ratings provide additional design margin and do not degrade circuit performance in applications rated for 1500V operation.

Q: What is the difference between X7R and C0G/NP0 temperature coefficients?

A: X7R provides ±15% capacitance variation across the -55°C to 125°C operating range. C0G/NP0 provides superior stability with ±0.3% per °C maximum variation. Both are acceptable for general-purpose applications; C0G/NP0 is preferred for precision circuits requiring tighter capacitance tolerance across temperature extremes.

Q: Does the thickness difference between 1812GA471JAT1A (0.087") and other substitutes (0.071") affect PCB compatibility?

A: The 1812GA471JAT1A has increased thickness of 0.087" compared to 0.071" for other parts. Verify PCB layout clearance above the component to ensure no interference with adjacent components or solder mask coverage. The footprint remains identical at 1812 (4532 Metric).

Q: Are all substitute parts available in the same packaging options?

A: 1812GA471JAT1A is available in Cut Tape (CT) and Digi-Reel packaging. 1812GC471KAT1A, 1812HC471KAT1A, and KGM43ER73U471KV are available in Tape & Reel (TR) format. Confirm packaging availability with your supplier for production requirements.

Q: What tolerance should I select for my application?

A: The original part specifies ±20% tolerance. Substitute parts with ±10% or ±5% tolerance provide tighter capacitance control. Select based on circuit requirements: general-purpose applications accept ±20%; precision filtering or timing circuits benefit from ±10% or ±5% specifications.

Q: Are all parts ROHS3 compliant and MSL 1 rated?

A: Yes. All listed parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, meeting the same environmental and handling requirements as the primary part.
