1812SC472MAT3A\SB Ceramic Capacitor Equivalent & Substitute Parts

Part Overview

The 1812SC472MAT3A\SB is a 4700 pF high-voltage ceramic capacitor manufactured by KYOCERA AVX with an X7R temperature coefficient and 1500V rated voltage. This surface-mount MLCC (multilayer ceramic capacitor) in 1812 (4532 metric) package is designed for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is ROHS3 compliant with MSL 1 rating and is currently in active production status with 1085 units in stock. Equivalent and substitute parts are identified based on matching capacitance value, package size, temperature coefficient, and voltage rating compatibility within the allowed electrical parameters for this product category.

Substitute Part Grouping Explanation

Substitute parts for the 1812SC472MAT3A\SB are qualified based on the following criteria:

Matching Parameters (Required for Substitution):

• Capacitance: 4700 pF (exact match)
• Package / Case: 1812 (4532 Metric) (exact match)
• Temperature Coefficient: X7R (exact match)
• Mounting Type: Surface Mount, MLCC (exact match)
• Operating Temperature Range: -55°C ~ 125°C (exact match)
• RoHS Status: ROHS3 Compliant (exact match)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match)

Allowable Variations:

• Voltage - Rated: Substitutes may have equal or higher voltage ratings (1500V or greater)
• Tolerance: Substitutes may have equal or tighter tolerance specifications (±20% or better)
• Manufacturer: KYOCERA AVX (same manufacturer, different part series)
• Packaging Format: Cut Tape (CT), Digi-Reel®, or Tape & Reel (TR) formats are interchangeable for component selection purposes

All three substitute parts meet these criteria and are direct functional equivalents for the 1812SC472MAT3A\SB in applications where the original part is specified.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are qualified replacements for the 1812SC472MAT3A\SB based on electrical and mechanical compatibility. Selection among the substitutes should be based on the following factors:

Voltage Rating Consideration: All substitute parts feature a 2000V (2kV) rated voltage, which is 500V higher than the original 1500V specification. This higher voltage rating provides additional safety margin in applications and is fully compatible with circuits designed for 1500V operation.

Tolerance Selection:

• For applications requiring ±20% tolerance matching: 1812GC472MAT1A is the direct equivalent
• For applications benefiting from tighter ±10% tolerance: 1812GC472KAT1A or KGM43FR73D472KV provide improved capacitance accuracy

Series and Packaging:

• 1812GC472KAT1A: Standard GC series, available in Cut Tape (CT) and Digi-Reel® packaging
• 1812GC472MAT1A: Standard GC series, available in Tape & Reel (TR) packaging
• KGM43FR73D472KV: KGM HV series, available in Tape & Reel (TR) packaging

All parts maintain ROHS3 compliance, MSL 1 rating, and REACH unaffected status. All are in active production with adequate inventory availability.

Frequently Asked Questions (FAQ)

Q: Can 1812GC472KAT1A, 1812GC472MAT1A, or KGM43FR73D472KV be used as direct replacements for 1812SC472MAT3A\SB?

A: Yes. All three parts are direct functional equivalents. They share identical capacitance (4700 pF), package size (1812/4532 metric), temperature coefficient (X7R), operating temperature range (-55°C to 125°C), and compliance certifications. The substitute parts feature higher voltage ratings (2000V vs. 1500V) and equal or tighter tolerance specifications, making them fully compatible with applications designed for the original part.

Q: What is the difference between the three substitute parts?

A: The primary differences are tolerance and packaging format. 1812GC472MAT1A maintains ±20% tolerance matching the original part and uses Tape & Reel packaging. 1812GC472KAT1A and KGM43FR73D472KV both offer tighter ±10% tolerance. 1812GC472KAT1A is available in Cut Tape and Digi-Reel formats, while KGM43FR73D472KV is part of the KGM HV series and uses Tape & Reel packaging.

Q: Why do the substitute parts have higher voltage ratings?

A: The substitute parts are rated for 2000V (2kV) compared to the original 1500V (1.5kV) specification. This higher voltage rating is an allowable variation that does not affect compatibility. Circuits designed for 1500V operation function correctly with 2000V-rated components, which provide additional voltage margin and safety.

Q: Are there any dimensional differences between the original and substitute parts?

A: All parts use the 1812 (4532 metric) package with identical length (0.181" / 4.60mm) and width (0.126" / 3.20mm). Maximum thickness is 0.087" (2.20mm) for the original and first two substitutes, with KGM43FR73D472KV at 0.087" (2.21mm)—a negligible 0.01mm difference that does not affect PCB assembly or mechanical fit.

Q: Do all parts meet the same compliance and environmental standards?

A: Yes. All four parts are ROHS3 compliant, have MSL 1 (Unlimited) moisture sensitivity rating, and REACH unaffected status. All are in active production status with equivalent reliability and environmental qualification.

Q: Which substitute should I select for new designs?

A: Selection depends on tolerance requirements and packaging preferences. For tolerance-critical applications, 1812GC472KAT1A or KGM43FR73D472KV (±10%) are preferred. For standard applications, 1812GC472MAT1A (±20%) provides cost-effective equivalence. Packaging format (Cut Tape, Digi-Reel, or Tape & Reel) should align with your assembly process requirements.
