Substitute Part Grouping Explanation

Substitution eligibility for the 1825HC472MAT1A is determined by strict equivalence in the following critical parameters:

• Capacitance value: 4700 pF (exact match required)
• Voltage rating: 3000V (3kV) minimum (equal or higher acceptable)
• Temperature coefficient: X7R (required for thermal stability equivalence)
• Package format: 1825 (4564 Metric) (mechanical and electrical compatibility requirement)
• Mounting type: Surface Mount, MLCC (assembly process compatibility)
• Physical dimensions: 0.177" L x 0.252" W, 0.100" max thickness (PCB layout compatibility)
• Compliance: ROHS3 and REACH status (regulatory equivalence)

The identified substitute part 1825HC472KAT1A meets all critical substitution criteria while offering improved capacitance tolerance (±10% versus ±20%), representing an upgrade path for applications requiring tighter tolerance specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 1825HC472MAT1A and 1825HC472KAT1A are Active status products from KYOCERA AVX with full ROHS3 compliance and REACH Unaffected designation, ensuring regulatory equivalence for applications subject to environmental standards.

The primary differentiation between these parts is capacitance tolerance: the main part specifies ±20% tolerance, while the substitute part 1825HC472KAT1A provides ±10% tolerance. This tighter tolerance specification in the substitute part represents improved component consistency and may be selected for applications where capacitance value stability is a design requirement.

Packaging format differs between the two parts: the main part is supplied in Tape & Reel (TR) format, while the substitute is available in Cut Tape (CT) and Digi-Reel® format. Selection between these packaging options depends on procurement volume and assembly line requirements rather than electrical or mechanical compatibility.

Both parts maintain identical electrical ratings, thermal characteristics, and physical dimensions, confirming direct substitutability at the circuit level.

Frequently Asked Questions (FAQ)

Q: Can 1825HC472KAT1A replace 1825HC472MAT1A in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent. The substitute part offers improved capacitance tolerance (±10% versus ±20%), making it suitable for direct substitution. Physical dimensions, voltage rating, temperature coefficient, and package footprint are identical.

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

A: Tolerance defines the acceptable range of actual capacitance values around the nominal 4700 pF specification. The ±20% tolerance allows values between 3760 pF and 5640 pF, while ±10% tolerance restricts values to 4230 pF to 5170 pF. Tighter tolerance (±10%) provides greater capacitance consistency and is preferred for precision applications.

Q: Are the packaging formats interchangeable?

A: Packaging formats (Tape & Reel versus Cut Tape & Digi-Reel®) affect procurement and assembly logistics but do not impact electrical or mechanical compatibility. Selection depends on production volume and assembly equipment compatibility rather than circuit performance.

Q: Do both parts meet the same compliance standards?

A: Yes. Both 1825HC472MAT1A and 1825HC472KAT1A are ROHS3 compliant and REACH Unaffected, confirming equivalent regulatory status for applications subject to environmental and hazardous substance restrictions.

Q: Is the 1825 package format critical for substitution?

A: Yes. The 1825 (4564 Metric) package format is a critical substitution parameter. Both parts share identical physical dimensions (0.177" L x 0.252" W, 0.100" max thickness), ensuring PCB layout compatibility and assembly process compatibility without design modification.
