Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1825SC472MAT9A is determined by the following critical parameters:

Fixed Parameters (Must Match):

• Capacitance: 4700 pF
• Temperature Coefficient: X7R
• Package / Case: 1825 (4564 Metric)
• Physical Dimensions: 0.177" L x 0.252" W (4.50mm x 6.40mm)
• Thickness (Max): 0.100" (2.54mm)
• Mounting Type: Surface Mount, MLCC
• Operating Temperature Range: -55°C ~ 125°C

Variable Parameters (Allowed to Differ):

• Voltage - Rated: Can be equal to or higher than 1500V
• Tolerance: Can be equal to or tighter than ±20%
• RoHS Status: Must maintain ROHS3 Compliance
• Moisture Sensitivity Level: Must maintain MSL 1 (Unlimited)

The identified substitute parts maintain identical capacitance, package, and thermal characteristics while offering enhanced voltage ratings and improved tolerance specifications. Both substitute parts are manufactured by KYOCERA AVX and retain full compliance with regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and full ROHS3 compliance with unlimited moisture sensitivity level (MSL 1), ensuring long-term availability and regulatory adherence for production applications.

1825SC472MAT9A (Main Part): Suitable for applications with 1500V maximum operating voltage and tolerance requirements of ±20%. This configuration provides baseline performance for general-purpose high-voltage applications.

1825HC472KAT1A (Upgrade Option): Rated at 3000V (3kV) with ±10% tolerance, this part provides the highest voltage margin and tightest tolerance specification. Selection is appropriate for designs requiring maximum voltage headroom or enhanced capacitance accuracy. Inventory availability is 2400 units.

1825WC472KAT1A (Mid-Range Option): Rated at 2500V (2.5kV) with ±10% tolerance, this part offers intermediate voltage rating and improved tolerance. Selection is appropriate for designs requiring voltage margin above 1500V with enhanced accuracy. Inventory availability is 845 units.

All substitute parts share identical physical dimensions, package configuration, and thermal operating range, ensuring direct mechanical and electrical compatibility within the specified parameter constraints.

Frequently Asked Questions (FAQ)

Q: Can 1825HC472KAT1A or 1825WC472KAT1A be used as direct replacements for 1825SC472MAT9A?

A: Yes, both substitute parts are direct replacements. They maintain identical capacitance (4700 pF), package (1825), physical dimensions, and thermal characteristics. The substitute parts offer higher voltage ratings and improved tolerance, making them suitable for applications originally designed for the 1825SC472MAT9A.

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

A: The primary difference is voltage rating. The 1825HC472KAT1A is rated at 3000V (3kV), while the 1825WC472KAT1A is rated at 2500V (2.5kV). Both offer ±10% tolerance compared to the main part's ±20% tolerance. Selection depends on the specific voltage requirements of the application.

Q: Are there any tolerance differences between the main part and substitutes?

A: Yes. The 1825SC472MAT9A has ±20% tolerance, while both substitute parts (1825HC472KAT1A and 1825WC472KAT1A) have ±10% tolerance. Tighter tolerance in substitute parts may improve circuit performance in applications sensitive to capacitance variation.

Q: Do all parts have the same physical dimensions?

A: Yes. All three parts use the 1825 (4564 Metric) package with identical dimensions of 0.177" L x 0.252" W (4.50mm x 6.40mm) and maximum thickness of 0.100" (2.54mm). They are mechanically interchangeable on PCB layouts.

Q: What is the moisture sensitivity level (MSL) for these parts?

A: All three parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These parts do not require special moisture control during storage, handling, or assembly.

Q: Are all parts ROHS3 compliant?

A: Yes. The 1825SC472MAT9A, 1825HC472KAT1A, and 1825WC472KAT1A are all ROHS3 compliant, meeting regulatory requirements for hazardous substance restrictions.

Q: What is the operating temperature range for these capacitors?

A: All three parts operate across the identical temperature range of -55°C to 125°C with X7R temperature coefficient, ensuring stable capacitance performance throughout this range.
