Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1825SC472MAT3A\SB is determined by the following critical parameters:

Fixed Parameters (Must Match):

• Capacitance: 4700 pF
• Temperature Coefficient: X7R
• Mounting Type: Surface Mount, MLCC
• Package / Case: 1825 (4564 Metric)
• Physical Dimensions: 0.177" L x 0.252" W (4.50mm x 6.40mm)
• Operating Temperature Range: -55°C ~ 125°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Variable Parameters (Allowed to Differ):

• Voltage - Rated: 1500V (1.5kV) or higher
• Tolerance: ±20% or tighter (±10%)
• Packaging Format: Cut Tape (CT), Digi-Reel®, or Tape & Reel (TR)

All identified substitute parts maintain identical capacitance, package footprint, and thermal characteristics while offering enhanced voltage ratings and improved tolerance specifications. These upgrades provide design margin and component interchangeability without requiring PCB modifications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and ROHS3 compliance, ensuring regulatory alignment with the original 1825SC472MAT3A\SB specification. The three identified alternatives provide voltage rating upgrades while preserving identical physical footprint and thermal performance characteristics.

1825HC472KAT1A offers the highest voltage rating at 3000V (3kV) with improved ±10% tolerance and is available in Cut Tape (CT) and Digi-Reel® packaging formats.

1825HC472MAT1A provides 3000V (3kV) rating with ±20% tolerance matching the original part's tolerance specification and is supplied in Tape & Reel (TR) format.

1825WC472KAT1A delivers intermediate voltage performance at 2500V (2.5kV) with ±10% tolerance, offering a balanced upgrade option between the original 1500V rating and the 3000V alternatives.

All substitute parts are manufactured by KYOCERA AVX, maintaining consistent quality and reliability standards. Selection between alternatives depends on application voltage requirements, tolerance specifications, and packaging format compatibility with assembly processes.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts share identical capacitance (4700 pF), temperature coefficient (X7R), package footprint (1825/4564 Metric), and physical dimensions (0.177" L x 0.252" W x 0.100" max thickness). The 1825HC472KAT1A provides upgraded voltage rating (3000V vs. 1500V) and improved tolerance (±10% vs. ±20%), making it a direct PCB-compatible substitute without layout modifications.

Q: What is the difference between 1825HC472KAT1A and 1825HC472MAT1A?

A: Both parts are rated for 3000V (3kV) with identical capacitance and package specifications. The primary differences are tolerance (±10% vs. ±20%) and packaging format (Cut Tape/Digi-Reel® vs. Tape & Reel). Selection depends on assembly equipment compatibility and tolerance requirements for the application.

Q: Why would I choose 1825WC472KAT1A over the 3000V alternatives?

A: The 1825WC472KAT1A provides 2500V (2.5kV) rating with ±10% tolerance, offering a middle-ground option. This part is suitable when application voltage requirements fall between 1500V and 3000V, potentially offering cost optimization while maintaining improved tolerance compared to the original 1500V part.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts (1825HC472KAT1A, 1825HC472MAT1A, and 1825WC472KAT1A) maintain ROHS3 compliance and REACH Unaffected status, matching the regulatory requirements of the original 1825SC472MAT3A\SB.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: All parts, including the original and all substitutes, are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Can these parts be used interchangeably in the same circuit?

A: Yes, provided the application voltage rating does not exceed 1500V (1.5kV). If the circuit operates above 1500V, only the substitute parts with higher voltage ratings (1825HC472KAT1A, 1825HC472MAT1A, or 1825WC472KAT1A) are suitable. All parts maintain identical capacitance and thermal characteristics, ensuring functional equivalence within their respective voltage specifications.
