Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1825AC472MAT3A is determined by the following criteria:

Fixed Parameters (Must Match):

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

Variable Parameters (Allowed to Differ):

• Voltage Rating: May be equal or higher than 1000V
• Tolerance: May be tighter (lower) or equal to ±20%
• Temperature Coefficient: May differ (X7R, C0G/NP0)
• Thickness: Minor variations permitted within component specifications
• Packaging Format: Tape & Reel (TR), Cut Tape (CT), or equivalent

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and active product status.

Parameter Comparison

Engineering Selection Recommendations

1825AA472JAT1A (C0G/NP0, 1kV, ±5%) Select this substitute when tighter capacitance tolerance is required. The C0G/NP0 temperature coefficient provides superior stability across the operating temperature range compared to X7R. Voltage rating matches the original specification. Thickness increases to 0.110" (2.80mm); verify PCB layout clearance. Highest inventory availability (1135 units).

1825HC472KAT1A (X7R, 3kV, ±10%) Select this substitute for applications requiring higher voltage margin or operating in elevated voltage stress conditions. Maintains X7R temperature coefficient matching the original part. Tolerance tightens to ±10%. Largest inventory stock (2400 units). Packaging format is Cut Tape (CT) & Digi-Reel®.

1825HC472MAT1A (X7R, 3kV, ±20%) Select this substitute as a direct functional upgrade with identical tolerance and temperature coefficient to the original part. Voltage rating increases to 3kV for enhanced reliability margin. Maintains 0.100" (2.54mm) thickness. Packaging format is Tape & Reel (TR).

1825WC472KAT1A (X7R, 2.5kV, ±10%) Select this substitute for intermediate voltage requirement applications. Provides voltage upgrade to 2.5kV with tighter tolerance (±10%). Maintains X7R temperature coefficient and 0.100" (2.54mm) thickness. Inventory: 845 units.

All substitute parts are ROHS3 compliant, MSL 1 rated, and active in production status.

Frequently Asked Questions (FAQ)

Q: Can 1825AA472JAT1A replace 1825AC472MAT3A in all applications? A: Yes, provided the application tolerates the increased thickness of 0.110" (2.80mm) versus 0.100" (2.54mm). The C0G/NP0 temperature coefficient offers superior stability. Verify PCB layout accommodates the thickness increase.

Q: What is the primary difference between X7R and C0G/NP0 temperature coefficients? A: X7R provides ±15% capacitance change across -55°C to 125°C. C0G/NP0 provides ±30 ppm/°C, resulting in superior stability. Select C0G/NP0 for precision applications; X7R for general purpose applications.

Q: Can I use a higher voltage rated part as a substitute? A: Yes. Higher voltage ratings (1825HC472KAT1A at 3kV, 1825WC472KAT1A at 2.5kV) are direct substitutes for the 1kV original part. Higher voltage ratings provide additional safety margin and reliability in the circuit.

Q: Does packaging format affect electrical performance? A: No. Tape & Reel (TR), Cut Tape (CT), and Digi-Reel® are handling and delivery formats only. Electrical specifications remain identical. Select based on assembly line equipment compatibility and inventory requirements.

Q: Are all substitute parts RoHS compliant? A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original 1825AC472MAT3A specification.

Q: What tolerance should I select for my application? A: ±20% tolerance (original and 1825HC472MAT1A) is suitable for general purpose filtering and coupling applications. ±10% tolerance (1825HC472KAT1A, 1825WC472KAT1A) provides tighter performance. ±5% tolerance (1825AA472JAT1A) is required for precision timing and frequency-critical circuits.
