KYOCERA AVX 1825GC472MAT9A Equivalent & Substitute Parts

Part Overview

The KYOCERA AVX 1825GC472MAT9A is a 4700 pF ceramic capacitor rated for 2000V (2kV) with X7R temperature coefficient, housed in a 1825 (4564 Metric) surface mount package. This high-voltage multilayer ceramic capacitor (MLCC) is designed for general-purpose applications requiring stable capacitance across a wide operating temperature range of -55°C to 125°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified when they maintain the same capacitance value, package footprint, and temperature coefficient while meeting or exceeding voltage and tolerance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1825GC472MAT9A is determined by the following criteria:

Primary Matching Parameters:

• Capacitance value: 4700 pF (exact match required)
• Package / Case: 1825 (4564 Metric) (exact match required)
• Temperature Coefficient: X7R (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)

Allowable Variation Parameters:

• Voltage Rating: Equal to or greater than 2000V
• Tolerance: Equal to or tighter than ±20%
• Manufacturer: Different manufacturers permitted if all primary parameters match

Substitute parts are grouped into two categories: upgrade substitutes (higher voltage rating or tighter tolerance) and equivalent substitutes (same electrical specifications from alternative manufacturers).

Engineering Selection Recommendations

1825HC472KAT1A (KYOCERA AVX) - Upgrade Substitute

This part provides a direct upgrade path with a 3000V (3kV) voltage rating and tighter ±10% tolerance compared to the 1825GC472MAT9A. All primary parameters match exactly. The higher voltage rating provides additional design margin for applications subject to voltage transients or overvoltage conditions. The improved tolerance specification reduces capacitance variation across the production batch. Both parts maintain ROHS3 compliance and MSL 1 rating. This substitute is suitable for designs requiring enhanced reliability or stricter capacitance control.

1825WC472KAT1A (KYOCERA AVX) - Upgrade Substitute

This part offers an intermediate voltage upgrade to 2500V (2.5kV) with ±10% tolerance. All primary parameters match the main part. The 500V voltage margin above the original specification provides additional safety headroom while maintaining the same physical footprint and thermal characteristics. This substitute is appropriate for applications where moderate voltage margin improvement is desired without transitioning to the higher 3kV rating.

C1825C472MGRAC7800 (KEMET) - Equivalent Substitute

This KEMET part maintains identical electrical specifications to the 1825GC472MAT9A: 4700 pF capacitance, 2000V voltage rating, ±20% tolerance, and X7R temperature coefficient. The package footprint, operating temperature range, and compliance certifications are equivalent. KEMET specifies this part as part of the SMD Comm X7R HV series with low ESL characteristics. Both parts are ROHS3 compliant with MSL 1 rating. This substitute is suitable for direct replacement in applications where manufacturer diversification is required or when KEMET supply chain availability is preferred.

Frequently Asked Questions (FAQ)

Q: Can I use 1825HC472KAT1A as a direct replacement for 1825GC472MAT9A?

A: Yes. The 1825HC472KAT1A is a direct substitute with identical capacitance (4700 pF), package (1825), temperature coefficient (X7R), and operating temperature range. The higher voltage rating (3kV vs. 2kV) and tighter tolerance (±10% vs. ±20%) make it a compatible upgrade.

Q: What is the difference between the two KYOCERA AVX upgrade options?

A: The 1825HC472KAT1A provides 3000V rating with ±10% tolerance, while the 1825WC472KAT1A provides 2500V rating with ±10% tolerance. Both offer tighter tolerance than the original part. Select based on your circuit's voltage requirements and design margin specifications.

Q: Is the KEMET C1825C472MGRAC7800 electrically equivalent to the KYOCERA AVX 1825GC472MAT9A?

A: Yes. Both parts have identical capacitance (4700 pF), voltage rating (2000V), tolerance (±20%), and temperature coefficient (X7R). The KEMET part is specified with low ESL characteristics. Physical dimensions and compliance ratings are equivalent.

Q: Will these substitutes fit the same PCB footprint?

A: Yes. All substitute parts use the 1825 (4564 Metric) package with identical physical dimensions of 0.177" L x 0.252" W (4.50mm x 6.40mm). They are pin-compatible and require no PCB layout modifications.

Q: Are all these parts RoHS compliant?

A: Yes. The main part and all substitute parts are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level), making them suitable for standard manufacturing and storage conditions.

Q: Which substitute should I choose for a high-reliability application?

A: The 1825HC472KAT1A is recommended for high-reliability applications due to its higher voltage rating (3kV) providing additional design margin and tighter tolerance (±10%) ensuring more consistent capacitance values across production batches.
