1812SC471MATME Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The 1812SC471MATME is a 470 pF high-voltage ceramic capacitor manufactured by KYOCERA AVX, rated for 1500V operation with X7R temperature coefficient characteristics. This surface-mount multilayer ceramic capacitor (MLCC) in 1812 (4532 metric) package is designed for general-purpose high-voltage applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part maintains active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when design requirements necessitate higher voltage ratings, improved tolerance specifications, or alternative temperature coefficient performance while maintaining the same capacitance value and package footprint.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1812SC471MATME is determined by the following criteria:

Fixed Parameters (Non-Negotiable):

• Capacitance value: 470 pF
• Package type: 1812 (4532 metric)
• Mounting type: Surface mount MLCC
• Physical footprint: 0.181" L × 0.126" W
• Operating temperature range: -55°C to 125°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)
• Product status: Active

Variable Parameters (Substitution Basis):

• Voltage rating: May be equal or higher than 1500V
• Tolerance: May be tighter (lower percentage) than ±20%
• Temperature coefficient: May differ (X7R or C0G/NP0)
• Thickness: May vary based on voltage rating requirements

The identified substitute parts maintain identical capacitance, package, and mounting specifications while offering enhanced voltage ratings (2000V or 3000V) and improved tolerance performance (±5% or ±10%). All substitutes retain active product status and full compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status and full ROHS3 compliance with unlimited moisture sensitivity rating, ensuring compatibility with standard manufacturing and assembly processes.

2000V Voltage Rating Substitutes: The 1812GA471JAT1A offers the tightest tolerance specification (±5%) with C0G/NP0 temperature coefficient, providing superior capacitance stability across temperature extremes. The 1812GA471KAT1A and 1812GC471KAT1A both provide 2000V rating with ±10% tolerance; selection between these depends on temperature coefficient requirements (C0G/NP0 versus X7R). The 1812GC471KAT1A maintains identical thickness (0.071") to the original part, while the C0G/NP0 variants increase to 0.087" thickness due to dielectric material properties.

3000V Voltage Rating Substitutes: The 1812HC471KAT1A and KGM43ER73U471KV both provide 3000V rating with X7R temperature coefficient and ±10% tolerance. Both maintain the original 0.071" thickness specification. The KGM43ER73U471KV belongs to the KGM - HV series designation, indicating specialized high-voltage design optimization.

Selection among substitutes should be based on circuit voltage margin requirements and tolerance specifications necessary for the application. All parts are available in active inventory with REACH unaffected status.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with higher voltage rating in place of the 1812SC471MATME?

A: Yes. All identified substitutes maintain the same 470 pF capacitance value, 1812 package footprint, and surface-mount configuration. Higher voltage ratings provide additional design margin and do not compromise circuit functionality when the original 1500V rating is sufficient. Physical footprint compatibility is maintained across all substitutes.

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

A: X7R temperature coefficient specifies capacitance variation of ±15% across the -55°C to 125°C operating range. C0G/NP0 provides superior stability with ±0.3% per °C maximum drift, resulting in tighter overall capacitance tolerance across temperature extremes. Selection depends on circuit sensitivity to capacitance variation with temperature.

Q: Do the substitute parts with increased thickness (0.087") create assembly compatibility issues?

A: The 1812GA471JAT1A and 1812GA471KAT1A increase thickness to 0.087" (2.20mm) compared to the original 0.071" (1.80mm). This 0.016" (0.40mm) increase may affect PCB layout clearance in space-constrained designs. The 1812GC471KAT1A, 1812HC471KAT1A, and KGM43ER73U471KV maintain the original 0.071" thickness and are preferred for designs with strict height limitations.

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

A: The 1812SC471MATME is supplied in standard packaging. Substitute parts are available in Cut Tape (CT) & Digi-Reel® (1812GA471JAT1A) or Tape & Reel (TR) formats (remaining substitutes). Packaging selection should align with procurement and assembly requirements.

Q: What compliance certifications apply to all parts in this substitution group?

A: All parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 (unlimited moisture sensitivity) rating. ECCN classification is EAR99 for all parts except KGM43ER73U471KV (HTSUS 8532.23.0020 versus 8532.24.0020 for others), reflecting minor tariff classification differences without affecting technical compatibility.
