Substitute Part Grouping Explanation

Substitution for the 1825HC472MATME is determined by strict equivalence in the following critical parameters:

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

Substitute parts are grouped into two categories based on tolerance specification:

1. Upgrade Substitute (Tighter Tolerance): 1825HC472KAT1A features ±10% tolerance, providing improved capacitance accuracy compared to the ±20% tolerance of the main part.

2. Parametric Equivalent (Identical Tolerance): 1825HC472MAT1A maintains ±20% tolerance matching the main part specification.

Both substitutes maintain identical electrical performance, compliance certifications, and physical form factor. Differentiation is based solely on packaging format and tolerance specification.

Parameter Comparison

Engineering Selection Recommendations

All three parts—1825HC472MATME, 1825HC472KAT1A, and 1825HC472MAT1A—are active production components from KYOCERA AVX with full ROHS3 compliance and REACH unaffected status. Selection between these parts is based on packaging format and tolerance requirements:

• 1825HC472MATME: Cut Tape (CT) & Digi-Reel® packaging. Use when standard packaging formats are required for automated assembly lines.

• 1825HC472KAT1A: Cut Tape (CT) & Digi-Reel® packaging with ±10% tolerance. Select when tighter capacitance accuracy is required for circuit performance or when tolerance specifications mandate improved precision.

• 1825HC472MAT1A: Tape & Reel (TR) packaging with ±20% tolerance. Use when bulk reel packaging is preferred for high-volume production runs or when tolerance matching the main part specification is required.

All parts maintain identical electrical characteristics, thermal performance, and regulatory compliance. Substitution is mechanically and electrically transparent across all three variants.

Frequently Asked Questions (FAQ)

Q: Can 1825HC472KAT1A replace 1825HC472MATME in existing designs?

A: Yes. The 1825HC472KAT1A is a direct electrical and mechanical substitute. The ±10% tolerance provides improved capacitance accuracy compared to the ±20% tolerance of the main part, making it suitable for applications where tighter tolerance is beneficial or required.

Q: What is the difference between Cut Tape (CT) & Digi-Reel® and Tape & Reel (TR) packaging?

A: Cut Tape (CT) & Digi-Reel® packaging provides components in smaller quantities on cut tape with optional reel format, suitable for lower-volume or mixed-component assembly. Tape & Reel (TR) packaging supplies components on full reels, optimized for high-volume automated production. Both formats are compatible with standard pick-and-place equipment.

Q: Are all three parts suitable for high-voltage applications?

A: Yes. All three parts are rated for 3000V (3kV) and feature X7R temperature coefficient characteristics, making them suitable for high-voltage general-purpose applications across the -55°C to 125°C operating range.

Q: Does tolerance affect circuit performance?

A: Tolerance affects the actual capacitance value delivered. The ±10% tolerance of 1825HC472KAT1A ensures capacitance remains within a narrower range around the 4700 pF nominal value compared to the ±20% tolerance of 1825HC472MATME and 1825HC472MAT1A. Select based on circuit requirements for capacitance accuracy.

Q: Are all parts RoHS3 compliant?

A: Yes. All three parts—1825HC472MATME, 1825HC472KAT1A, and 1825HC472MAT1A—are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. All three parts share identical physical dimensions (0.177" L × 0.252" W × 0.100" thickness), package type (1825 / 4564 Metric), and mounting method (Surface Mount, MLCC). They are mechanically and electrically interchangeable on PCB layouts designed for the 1825 package footprint.
