• Tolerance: ±10% (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 x 0.100" max thickness (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Compliance: RoHS3 Compliant, REACH Unaffected (exact match required)

The identified substitute part 1825HC472KAT1A meets all electrical and mechanical requirements for direct substitution. The primary distinction between the main part and substitute is packaging configuration, which does not affect electrical performance or board-level compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the 1825HC472KAT3A\SB and 1825HC472KAT1A are Active products manufactured by KYOCERA AVX with identical electrical specifications and mechanical form factors. Selection between these parts should be based on packaging and supply chain requirements:

• 1825HC472KAT3A\SB: Select when standard packaging format is required or specified in procurement documentation.
• 1825HC472KAT1A: Select when Cut Tape (CT) or Digi-Reel® packaging is preferred for automated assembly processes or when higher inventory availability is a priority.

Both parts maintain full RoHS3 compliance and REACH Unaffected status, ensuring regulatory compatibility across all applications. The identical MSL 1 rating (Unlimited) eliminates moisture sensitivity considerations in component selection.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts are electrically and mechanically identical, with matching capacitance (4700 pF), voltage rating (3kV), temperature coefficient (X7R), package dimensions (1825/4564 Metric), and compliance certifications. The only difference is packaging format.

Q: What is the difference between the packaging formats?

A: 1825HC472KAT3A\SB uses standard packaging, while 1825HC472KAT1A is supplied in Cut Tape (CT) and Digi-Reel® formats. Both formats contain the same component; packaging format affects handling, storage, and automated assembly compatibility only.

Q: Are there any thermal or electrical performance differences between these parts?

A: No. Both parts share identical operating temperature range (-55°C ~ 125°C), X7R temperature coefficient, and all electrical ratings. Performance in circuit applications is equivalent.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both parts are RoHS3 Compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Regulatory and environmental compliance is identical.

Q: Which part should be selected for high-volume production?

A: Selection should be based on assembly equipment compatibility and supply chain availability. Cut Tape (CT) and Digi-Reel® packaging (1825HC472KAT1A) is typically preferred for automated pick-and-place assembly. Verify packaging compatibility with your manufacturing process before final selection.
