1825SC472MAT3A Equivalent & Substitute Parts

Part Overview

The 1825SC472MAT3A is a 4700 pF ceramic capacitor rated at 1500V (1.5kV) with X7R temperature coefficient, manufactured by KYOCERA AVX in 1825 (4564 Metric) surface mount package. This component is classified as Active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). The part is designed for general-purpose high-voltage applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. Substitute parts are identified to address inventory availability, voltage margin requirements, or tolerance specifications while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1825SC472MAT3A is determined by the following criteria:

Mandatory Compatibility Parameters:

• Capacitance value: 4700 pF (exact match required)
• Package type: 1825 (4564 Metric) surface mount MLCC (exact match required)
• Temperature coefficient: X7R (exact match required)
• Operating temperature range: -55°C to 125°C (exact match required)
• Physical dimensions: 4.50mm L × 6.40mm W × 2.54mm max thickness (exact match required)

Allowable Variation Parameters:

• Voltage rating: May be equal to or greater than 1500V
• Tolerance: May be ±10% or ±20%
• Packaging format: Cut Tape (CT), Digi-Reel®, or Tape & Reel (TR) formats are interchangeable

All substitute parts listed maintain identical capacitance, package geometry, and temperature performance while offering enhanced voltage ratings or improved tolerance specifications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory and supply chain continuity. Selection among the three substitute options depends on application voltage margin requirements:

1825HC472KAT1A provides the highest voltage rating at 3000V with improved ±10% tolerance and is available in Cut Tape (CT) and Digi-Reel® packaging formats. This option is suitable for applications requiring maximum voltage headroom and tighter capacitance tolerance.

1825HC472MAT1A offers 3000V rating with ±20% tolerance matching the original part's tolerance specification, available in Tape & Reel (TR) format. This option maintains tolerance consistency while providing doubled voltage margin.

1825WC472KAT1A provides intermediate voltage rating at 2500V with ±10% tolerance. This option balances voltage margin enhancement with improved tolerance specification.

All substitute parts are manufactured by KYOCERA AVX with identical MSL 1 (Unlimited) moisture sensitivity rating, ensuring equivalent handling and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can 1825HC472KAT1A be used as a direct replacement for 1825SC472MAT3A?

A: Yes. Both parts share identical capacitance (4700 pF), package geometry (1825/4564 Metric), temperature coefficient (X7R), and operating temperature range (-55°C to 125°C). The 1825HC472KAT1A provides higher voltage rating (3000V vs 1500V) and improved tolerance (±10% vs ±20%), making it electrically and mechanically compatible.

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

A: The three substitutes differ in voltage rating and tolerance. 1825HC472KAT1A and 1825HC472MAT1A both provide 3000V rating; the former has ±10% tolerance while the latter has ±20%. 1825WC472KAT1A provides 2500V rating with ±10% tolerance. All three maintain identical capacitance and package specifications.

Q: Are packaging format differences significant?

A: Packaging format (Cut Tape, Digi-Reel®, or Tape & Reel) affects handling and assembly processes but does not impact electrical or mechanical performance. Selection should align with manufacturing equipment and assembly line requirements.

Q: Does higher voltage rating affect circuit performance?

A: No. Higher voltage rating does not alter capacitance value, temperature coefficient, or operating temperature range. The component will perform identically in the circuit while providing additional voltage safety margin.

Q: Are all parts ROHS3 compliant?

A: Yes. The main part 1825SC472MAT3A and all three substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, ensuring equivalent environmental and regulatory compliance.
