Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1825CC472MAT3A are qualified based on the following criteria:

Identical Parameters (Required for Substitution):

• Capacitance: 4700 pF
• Package / Case: 1825 (4564 Metric)
• Physical Dimensions: 0.177" L x 0.252" W x 0.100" max thickness
• Temperature Coefficient: X7R
• Operating Temperature Range: -55°C ~ 125°C
• Mounting Type: Surface Mount, MLCC
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Variable Parameters (Basis for Substitution):

• Voltage Rating: 630V (main part) vs. 2500V, 3000V (substitutes)
• Tolerance: ±20% (main part) vs. ±10% (select substitutes)

All substitute parts maintain full compatibility with the original part's footprint, thermal performance, and regulatory compliance while offering enhanced voltage margin or improved capacitance tolerance.

Parameter Comparison

Engineering Selection Recommendations

1825HC472KAT1A (3kV, ±10% Tolerance)

• Highest voltage rating (3000V) with improved tolerance specification (±10%)
• Largest inventory availability (2400 units)
• Packaged in Cut Tape (CT) & Digi-Reel® format
• Suitable for applications requiring maximum voltage margin and tighter capacitance control

1825HC472MAT1A (3kV, ±20% Tolerance)

• Highest voltage rating (3000V) with original tolerance specification (±20%)
• Packaged in Tape & Reel (TR) format
• Maintains identical tolerance to main part while providing enhanced voltage capability
• Lower inventory (629 units)

1825WC472KAT1A (2.5kV, ±10% Tolerance)

• Intermediate voltage rating (2500V) with improved tolerance specification (±10%)
• Moderate inventory availability (845 units)
• Suitable for applications requiring voltage margin above 630V with tighter capacitance control

All substitute parts maintain full compliance with ROHS3 and REACH requirements, identical thermal performance across -55°C to 125°C operating range, and MSL 1 (Unlimited) moisture sensitivity rating. Selection should be based on circuit voltage requirements and tolerance specifications.

Frequently Asked Questions (FAQ)

Q: Can 1825HC472KAT1A be used as a direct replacement for 1825CC472MAT3A? A: Yes. Both parts share identical capacitance (4700 pF), package dimensions (1825/4564 Metric), temperature coefficient (X7R), and thermal operating range (-55°C ~ 125°C). The 1825HC472KAT1A provides higher voltage rating (3000V vs. 630V) and improved tolerance (±10% vs. ±20%), making it electrically compatible and functionally superior for the same footprint.

Q: What is the difference between 1825HC472KAT1A and 1825HC472MAT1A? A: Both parts have identical voltage rating (3000V) and package specifications. The primary difference is tolerance: 1825HC472KAT1A offers ±10% tolerance while 1825HC472MAT1A offers ±20% tolerance. Packaging also differs: 1825HC472KAT1A uses Cut Tape (CT) & Digi-Reel® format, while 1825HC472MAT1A uses Tape & Reel (TR) format.

Q: Why would I choose 1825WC472KAT1A over the 3kV options? A: The 1825WC472KAT1A provides a 2500V rating with ±10% tolerance. This option is suitable for applications requiring voltage margin above 630V but not requiring the full 3000V capability, while maintaining improved tolerance specifications.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All substitute parts (1825HC472KAT1A, 1825HC472MAT1A, and 1825WC472KAT1A) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the main part 1825CC472MAT3A.

Q: What packaging formats are available? A: The main part 1825CC472MAT3A is available in standard packaging. Substitute parts offer multiple packaging options: 1825HC472KAT1A in Cut Tape (CT) & Digi-Reel® format, 1825HC472MAT1A in Tape & Reel (TR) format, and 1825WC472KAT1A in standard packaging. All maintain identical component dimensions and footprint compatibility.

Q: Can these parts be used interchangeably in existing designs? A: Yes, provided the circuit design accommodates the higher voltage ratings. All substitute parts maintain identical physical dimensions, mounting type (Surface Mount, MLCC), and thermal characteristics. Designs rated for 630V can safely use higher-voltage substitutes without layout or thermal modifications.
