Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1825CC472MAT1A are qualified based on the following criteria:

Identical Parameters (Non-Negotiable):

• Capacitance: 4700 pF
• Temperature Coefficient: X7R
• Operating Temperature Range: -55°C to 125°C
• Package / Case: 1825 (4564 Metric)
• Mounting Type: Surface Mount, MLCC
• Physical Dimensions: 4.50mm L × 6.40mm W × 2.54mm Max Thickness
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: MSL 1

Variable Parameters (Substitution Basis):

• Voltage Rating: 630V (main part) → 2500V, 3000V (substitutes)
• Tolerance: ±20% (main part) → ±10% or ±20% (substitutes)

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and full ROHS3 compliance with REACH unaffected designation. Selection between the main part and substitutes depends on circuit voltage requirements:

1825CC472MAT1A (630V): Select for applications with maximum operating voltage at or below 630V. Suitable for general-purpose circuits with standard voltage margins.

1825HC472KAT1A (3000V, ±10%): Select for high-voltage applications requiring 3kV rating with tighter capacitance tolerance. Provides maximum voltage headroom and improved capacitance stability.

1825HC472MAT1A (3000V, ±20%): Select for high-voltage applications requiring 3kV rating while maintaining ±20% tolerance specification. Equivalent tolerance to the main part with enhanced voltage performance.

1825WC472KAT1A (2500V, ±10%): Select for intermediate voltage applications requiring 2.5kV rating with improved tolerance. Balances voltage performance and tolerance specifications.

All parts share identical physical dimensions, thermal characteristics, and moisture sensitivity ratings, ensuring direct mechanical and thermal compatibility in PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage-rated substitute in place of the 1825CC472MAT1A?

A: Yes. The 1825HC472KAT1A (3kV), 1825HC472MAT1A (3kV), and 1825WC472KAT1A (2.5kV) are direct substitutes with identical capacitance, package dimensions, and thermal characteristics. Higher voltage ratings provide additional safety margin in circuits operating below their rated voltage.

Q: What is the difference between ±10% and ±20% tolerance parts?

A: Tolerance specifies the allowable deviation from the nominal 4700 pF capacitance value. ±10% tolerance (1825HC472KAT1A, 1825WC472KAT1A) provides tighter capacitance accuracy (4230–5170 pF range) compared to ±20% tolerance (1825CC472MAT1A, 1825HC472MAT1A) with 3760–5640 pF range. Select ±10% for applications requiring precise capacitance values.

Q: Are the physical dimensions identical across all substitute parts?

A: Yes. All parts use the 1825 (4564 Metric) package with identical dimensions: 4.50mm length, 6.40mm width, and 2.54mm maximum thickness. Direct PCB layout compatibility is maintained across all substitutes.

Q: Do packaging format differences affect electrical performance?

A: No. Packaging formats (Cut Tape, Tape & Reel, standard) are logistics and handling specifications only. Electrical performance, capacitance, voltage rating, and thermal characteristics remain identical regardless of packaging format.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and REACH unaffected status, meeting identical regulatory requirements.
