1825PC474MAT1A Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The 1825PC474MAT1A is a 0.47 µF ceramic capacitor manufactured by KYOCERA AVX, rated for 250V with X7R temperature coefficient characteristics. This surface mount multilayer ceramic capacitor (MLCC) is designed for general purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is actively produced, ROHS3 compliant, and carries MSL 1 rating indicating unlimited moisture sensitivity protection. Substitute parts are identified for applications requiring improved tolerance specifications or alternative manufacturer sourcing while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1825PC474MAT1A are qualified based on the following electrical and mechanical parameters:

Mandatory Matching Parameters:

• Capacitance: 0.47 µF (exact match required)
• Voltage Rating: 250V (exact match required)
• Temperature Coefficient: X7R (exact match required)
• Package / Case: 1825 (4564 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)

Allowable Variation Parameters:

• Tolerance: ±20% (main part) to ±10% (substitute parts) - tighter tolerance is acceptable
• Thickness: 2.54mm (main part) to 2.00mm or 1.45mm (substitute parts) - reduced thickness is acceptable for space-constrained applications
• Manufacturer: KYOCERA AVX or KEMET - both manufacturers produce equivalent specifications

The identified substitute parts maintain all critical electrical parameters while offering improved tolerance specifications (±10% versus ±20%) and reduced physical thickness, providing design flexibility for applications with stricter capacitance accuracy requirements or compact board layouts.

Parameter Comparison

Engineering Selection Recommendations

1825PC474MAT1A (KYOCERA AVX - Original Part) Select this part for applications where ±20% capacitance tolerance is acceptable and standard thickness (2.54mm) is not a constraint. This part maintains active production status with ROHS3 compliance and MSL 1 rating.

1825PC474KAT1A (KYOCERA AVX - Upgrade Substitute) Select this part when improved capacitance accuracy (±10% tolerance) is required while maintaining the same manufacturer source. The reduced thickness (2.00mm) provides space savings for compact designs. Product status is active with full ROHS3 compliance and MSL 1 rating.

C1825C474KARAC7800 (KEMET - Cross-Manufacturer Substitute) Select this part for multi-source procurement strategies or when KEMET supply chain availability is preferred. This part offers the tightest thickness specification (1.45mm) for space-critical applications, combined with ±10% tolerance. Product status is active with ROHS3 compliance and MSL 1 rating.

All three parts are actively produced, ROHS3 compliant, and carry MSL 1 ratings, ensuring equivalent environmental and regulatory compliance for direct substitution in qualified applications.

Frequently Asked Questions (FAQ)

Q: Can 1825PC474KAT1A replace 1825PC474MAT1A in my design? A: Yes. Both parts share identical electrical specifications (0.47 µF, 250V, X7R, -55°C to 125°C), package dimensions (1825/4564 Metric), and mounting type. The substitute offers improved tolerance (±10% versus ±20%) and reduced thickness (2.00mm versus 2.54mm), making it a direct upgrade for applications requiring tighter capacitance accuracy.

Q: What is the difference between the KYOCERA AVX and KEMET substitute parts? A: Both substitute parts meet identical electrical requirements and package specifications. The primary differences are manufacturer source and thickness: KYOCERA AVX 1825PC474KAT1A has 2.00mm thickness, while KEMET C1825C474KARAC7800 has 1.45mm thickness. Both offer ±10% tolerance and are ROHS3 compliant with MSL 1 rating.

Q: Can I use the thinner KEMET part (1.45mm) in place of the original 2.54mm part? A: Yes, from an electrical and mechanical compatibility standpoint. The reduced thickness (1.45mm) is acceptable for the 1825 package footprint. Verify that your PCB assembly process and component placement equipment can accommodate the thinner profile without affecting solder joint quality or mechanical stability.

Q: Are all three parts ROHS3 compliant? A: Yes. The original part 1825PC474MAT1A and both substitute parts (1825PC474KAT1A and C1825C474KARAC7800) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, ensuring equivalent environmental compliance for direct substitution.

Q: Which substitute part should I choose for a space-constrained PCB design? A: The KEMET C1825C474KARAC7800 offers the minimum thickness specification (1.45mm) while maintaining all electrical and mechanical compatibility requirements. This part is optimal for applications where board height or component stack-up is a critical design constraint.

Q: Do these parts require different soldering or assembly processes? A: No. All three parts use identical Surface Mount, MLCC mounting technology with the same 1825 (4564 Metric) package footprint. Standard SMT assembly processes apply to all parts without modification.
