Substitute Part Grouping Explanation

Substitute parts for the 1825HC472KAT3A are identified based on strict electrical and mechanical parameter matching. The substitution criteria are:

• Capacitance value: 4700 pF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage rating: 3000V (3kV) minimum (exact match required)
• Temperature coefficient: X7R (exact match required)
• Operating temperature range: -55°C ~ 125°C (exact match required)
• Package / Case: 1825 (4564 Metric) (exact match required)
• Physical dimensions: 0.177" L x 0.252" W, 0.100" max thickness (exact match required)
• Mounting type: Surface Mount, MLCC (exact match required)
• Compliance: RoHS3 and REACH status (exact match required)

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both the 1825HC472KAT3A and 1825HC472KAT1A are Active products from KYOCERA AVX with identical electrical and mechanical specifications. Selection between these parts may be based on packaging format and inventory availability. The 1825HC472KAT3A is available in standard packaging, while the 1825HC472KAT1A is supplied in Cut Tape (CT) and Digi-Reel® formats. Both parts maintain full RoHS3 compliance and REACH Unaffected status, ensuring regulatory compliance for industrial and commercial applications. The unlimited MSL rating (MSL 1) eliminates moisture sensitivity concerns during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can 1825HC472KAT1A be used as a direct replacement for 1825HC472KAT3A?

A: Yes. Both parts are parametric equivalents with identical electrical specifications (4700 pF, ±10%, 3000V, X7R) and mechanical dimensions (1825 package, 0.177" x 0.252" x 0.100" max). The difference is packaging format only.

Q: What is the difference between the two part numbers?

A: The primary difference is packaging. The 1825HC472KAT3A uses standard packaging, while 1825HC472KAT1A is supplied in Cut Tape (CT) and Digi-Reel® formats. Electrical and mechanical specifications are identical.

Q: Are both parts RoHS3 compliant?

A: Yes. Both 1825HC472KAT3A and 1825HC472KAT1A are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What does MSL 1 (Unlimited) mean for this capacitor?

A: MSL 1 indicates unlimited moisture sensitivity. This part requires no special moisture control during storage, handling, or assembly, simplifying logistics and manufacturing processes.

Q: Can this capacitor be used in high-temperature applications?

A: Yes. The X7R temperature coefficient and -55°C ~ 125°C operating range support stable operation across industrial temperature extremes. Capacitance variation remains within ±10% tolerance across this range.

Q: Is the 1825 package suitable for automated assembly?

A: Yes. The 1825 (4564 Metric) surface-mount package is standard for automated pick-and-place assembly. Both Cut Tape and standard packaging formats support high-volume production.
