Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1825HC472MAT3A is determined by strict adherence to the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 4700 pF (exact match required)
• Voltage Rating: 3000V (3kV) (exact match required)
• Temperature Coefficient: X7R (exact match required)
• Package / Case: 1825 (4564 Metric) (exact match required)
• Physical Dimensions: 0.177" L x 0.252" W; Thickness 0.100" (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)

Allowable Variation Parameters:

• Tolerance: ±20% (main part) to ±10% (substitute acceptable as tighter tolerance)
• Packaging Configuration: Cut Tape (CT), Digi-Reel®, or Tape & Reel (TR) formats are interchangeable based on procurement requirements

Compliance Requirements:

• RoHS Status: ROHS3 Compliant (maintained across all substitutes)
• Moisture Sensitivity Level: 1 (Unlimited) (maintained across all substitutes)
• Product Status: Active (all substitutes must be active)

The identified substitutes meet all mandatory parameters while offering packaging flexibility and, in one case, improved tolerance specification.

Parameter Comparison

Engineering Selection Recommendations

1825HC472KAT1A (Upgrade Substitute): This part offers identical electrical and mechanical specifications to the main part with the advantage of tighter tolerance (±10% versus ±20%). All compliance certifications remain equivalent: ROHS3 compliant, MSL 1 (Unlimited), and Active product status. Selection of this substitute is appropriate when tighter capacitance tolerance is required for circuit performance. Packaging is available in Cut Tape (CT) and Digi-Reel® formats.

1825HC472MAT1A (Parametric Equivalent): This part maintains identical electrical specifications and tolerance (±20%) to the main part with full mechanical and compliance equivalence. The primary distinction is packaging format: Tape & Reel (TR) configuration versus Cut Tape (CT) and Digi-Reel® of the main part. Selection of this substitute is appropriate when Tape & Reel packaging is required for automated assembly processes. ROHS3 compliance and MSL 1 (Unlimited) rating are maintained.

Both substitutes are manufactured by KYOCERA AVX and carry Active product status, ensuring continued availability and support.

Frequently Asked Questions (FAQ)

Q: Can 1825HC472KAT1A be used as a direct replacement for 1825HC472MAT3A?

A: Yes. Both parts share identical capacitance (4700 pF), voltage rating (3000V), temperature coefficient (X7R), package (1825), and physical dimensions. The 1825HC472KAT1A features tighter tolerance (±10% versus ±20%), which is a functional improvement. All compliance certifications and operating temperature ranges are identical.

Q: What is the difference between 1825HC472MAT1A and 1825HC472MAT3A?

A: The electrical and mechanical specifications are identical: 4700 pF capacitance, ±20% tolerance, 3000V rating, X7R coefficient, and 1825 package. The difference is packaging format: 1825HC472MAT1A is supplied in Tape & Reel (TR) configuration, while 1825HC472MAT3A is supplied in Cut Tape (CT) and Digi-Reel® formats. Selection depends on assembly process requirements.

Q: Are all three parts ROHS3 compliant?

A: Yes. All three parts—1825HC472MAT3A, 1825HC472KAT1A, and 1825HC472MAT1A—are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which substitute should I select if tolerance is critical to my application?

A: Select 1825HC472KAT1A, which offers ±10% tolerance compared to ±20% tolerance of the main part and parametric equivalent. This tighter tolerance specification provides improved capacitance accuracy.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, all three parts are mechanically and electrically interchangeable on the PCB. Selection among them depends on packaging format availability (Cut Tape, Digi-Reel®, or Tape & Reel) and tolerance requirements for your specific application.

Q: What is the operating temperature range for all substitutes?

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