Substitute Part Grouping Explanation

Substitute parts for the 1825HC472MAT1A are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Parameters (Must Match Exactly):

• Capacitance: 4700 pF
• Voltage Rating: 3000V (3kV)
• Temperature Coefficient: X7R
• Package / Case: 1825 (4564 Metric)
• Physical Dimensions: 0.177" L x 0.252" W (4.50mm x 6.40mm)
• Thickness: 0.100" (2.54mm)
• Mounting Type: Surface Mount, MLCC
• Operating Temperature Range: -55°C to 125°C

Allowable Variations:

• Capacitance Tolerance: ±10% or ±20% (tighter tolerance acceptable)
• Packaging Format: Cut Tape (CT), Digi-Reel®, or Tape & Reel (TR)

All substitute parts maintain identical electrical performance and mechanical fit while offering alternative tolerance specifications and packaging options to accommodate different procurement and assembly requirements.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and full ROHS3 compliance, ensuring regulatory and supply chain continuity. Selection between the main part and substitutes should be based on the following factors:

1825HC472KAT1A (Upgrade Option): This part offers tighter capacitance tolerance (±10% versus ±20%), providing enhanced precision for applications requiring stricter capacitance specifications. The upgrade maintains identical electrical ratings, physical dimensions, and operating characteristics while offering improved tolerance performance.

1825HC472MAT1A (Parametric Equivalent): This part is electrically and mechanically identical to the main part specification, differing only in packaging format (Tape & Reel versus Cut Tape / Digi-Reel). Selection of this variant depends on assembly line requirements and procurement volume considerations.

All parts are manufactured by KYOCERA AVX and carry identical compliance certifications (ROHS3, REACH Unaffected, EAR99 ECCN classification). Substitution between these parts does not require design re-qualification or performance re-testing, as all critical electrical and mechanical parameters remain constant.

Frequently Asked Questions (FAQ)

Q: Can 1825HC472KAT1A replace 1825HC472MAT1A in my design?

A: Yes. The 1825HC472KAT1A is a direct substitute with identical capacitance (4700 pF), voltage rating (3kV), temperature coefficient (X7R), package dimensions (1825 / 4564 Metric), and operating temperature range (-55°C to 125°C). The only difference is tighter capacitance tolerance (±10% versus ±20%), which provides improved precision without affecting compatibility.

Q: What is the difference between the packaging formats listed?

A: Cut Tape (CT) & Digi-Reel® and Tape & Reel (TR) are different packaging and delivery formats for the same component. Cut Tape is suitable for lower-volume or mixed-component assembly, while Tape & Reel is optimized for high-volume automated pick-and-place assembly. The electrical and mechanical specifications of the capacitor remain identical regardless of packaging format.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed parts (1825HC472MAT1A, 1825HC472KAT1A, and the parametric equivalent 1825HC472MAT1A) are ROHS3 compliant and carry REACH Unaffected status, ensuring compliance with current environmental and regulatory requirements.

Q: Does the ±10% tolerance of 1825HC472KAT1A affect circuit performance compared to ±20% tolerance?

A: The ±10% tolerance specification of 1825HC472KAT1A provides a tighter capacitance range around the 4700 pF nominal value. This does not negatively affect performance; rather, it ensures more consistent capacitance values across production batches. Applications requiring precise capacitance specifications benefit from this tighter tolerance.

Q: Can these parts be used interchangeably in high-voltage applications?

A: Yes. All substitute parts maintain the 3000V (3kV) voltage rating, X7R temperature coefficient, and identical physical dimensions. They are fully interchangeable in high-voltage applications without design modification or performance degradation.

Q: What is the Moisture Sensitivity Level (MSL) significance?

A: All listed parts carry MSL 1 (Unlimited), indicating unlimited shelf life without moisture-related degradation. This eliminates moisture sensitivity concerns during storage, handling, and assembly processes.
