1825SC473MAT1A Equivalent & Substitute Parts

Part Overview

The 1825SC473MAT1A is a 0.047 µF ceramic capacitor manufactured by KYOCERA AVX, rated for 1500V (1.5kV) operation with X7R temperature coefficient characteristics. This surface-mount multilayer ceramic capacitor (MLCC) is designed for general-purpose high-voltage applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified to support design flexibility, inventory optimization, and supply chain continuity.

Substitute Part Grouping Explanation

Substitution of the 1825SC473MAT1A is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 0.047 µF (exact match required)
• Voltage Rating: 1500V minimum (1.5kV)
• Temperature Coefficient: X7R (ensures stable capacitance across temperature range)
• Package / Case: 1825 (4564 Metric) form factor
• Mounting Type: Surface Mount, MLCC
• Operating Temperature Range: -55°C to 125°C minimum
• Compliance: ROHS3 and REACH requirements

The substitute part C1825C473KFRAC7800 (KEMET) meets all critical electrical and mechanical parameters. Tolerance differences (±20% vs. ±10%) represent an upgrade in precision capability and do not prevent substitution. Physical thickness variation (2.54mm vs. 2.70mm) remains within acceptable assembly tolerances for 1825 package specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 1825SC473MAT1A and C1825C473KFRAC7800 are active production parts with full ROHS3 and REACH compliance. Selection between these parts is based on the following criteria:

1825SC473MAT1A (KYOCERA AVX): Select when tolerance of ±20% meets circuit requirements and KYOCERA AVX supply chain preference is established.

C1825C473KFRAC7800 (KEMET): Select when tighter tolerance of ±10% is required for improved capacitance accuracy. The SMD Comm X7R HV series designation and low ESL feature set support high-frequency and high-voltage applications. Thickness increase of 0.006" (0.16mm) remains within standard PCB assembly clearances for 1825 package specifications.

Both parts carry identical electrical ratings, temperature performance, and regulatory compliance. Physical footprint compatibility is confirmed for standard 1825 land patterns.

Frequently Asked Questions (FAQ)

Q: Can C1825C473KFRAC7800 be used as a direct replacement for 1825SC473MAT1A?

A: Yes. Both parts share identical capacitance (0.047 µF), voltage rating (1500V), temperature coefficient (X7R), operating temperature range (-55°C to 125°C), and 1825 package form factor. The substitute part offers improved tolerance (±10% vs. ±20%) and low ESL characteristics.

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

A: Tolerance defines the allowable deviation of actual capacitance from the nominal value. The ±10% tolerance of C1825C473KFRAC7800 provides tighter capacitance accuracy, beneficial for circuits requiring precise filtering or timing functions. The ±20% tolerance of 1825SC473MAT1A is acceptable for general-purpose applications where capacitance variation within this range does not affect circuit performance.

Q: Are there any PCB assembly considerations for the thickness difference?

A: The thickness difference of 0.006" (0.16mm) between parts is negligible for standard PCB assembly processes. Both parts fit within typical 1825 package height specifications and do not require design modifications to existing PCB layouts or reflow profiles.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both 1825SC473MAT1A and C1825C473KFRAC7800 are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations for electronic components.

Q: What is the moisture sensitivity level, and why is it important?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These parts do not require special moisture-controlled storage or handling procedures and can be stored under standard warehouse conditions indefinitely.
