1825GC472MAT1A Equivalent & Substitute Parts

Part Overview

The 1825GC472MAT1A is a 4700 pF ceramic capacitor rated at 2000V (2kV) with X7R temperature coefficient, manufactured by KYOCERA AVX in 1825 (4564 Metric) surface mount package. This high-voltage multilayer ceramic capacitor (MLCC) is designed for general-purpose applications requiring stable capacitance across a wide operating temperature range of -55°C to 125°C. The part is currently active in production with 827 units in stock. Equivalent and substitute parts are identified to provide design flexibility, accommodate supply chain variations, or meet specific performance requirements such as higher voltage ratings or improved tolerance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1825GC472MAT1A is determined by the following criteria:

Critical Parameters (Must Match):

• Capacitance: 4700 pF
• Temperature Coefficient: X7R
• Package / Case: 1825 (4564 Metric)
• Mounting Type: Surface Mount, MLCC
• Operating Temperature Range: -55°C to 125°C
• Physical Dimensions: 0.177" L × 0.252" W (4.50mm × 6.40mm)

Allowable Variation Parameters:

• Voltage Rating: Equal or higher than 2000V
• Tolerance: ±10% or ±20%
• Thickness: Up to 2.54mm
• Manufacturer: KYOCERA AVX or equivalent qualified manufacturer
• RoHS / REACH Compliance: ROHS3 Compliant, REACH Unaffected

Substitute parts are grouped into two categories: KYOCERA AVX upgrades with improved voltage ratings or tolerance specifications, and manufacturer-recommended alternatives from KEMET with equivalent electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and full compliance with ROHS3 and REACH requirements, ensuring regulatory compatibility with the original 1825GC472MAT1A.

KYOCERA AVX Upgrade Options (1825HC472KAT1A, 1825HC472MAT1A, 1825WC472KAT1A): These parts provide higher voltage ratings (3000V or 2500V) while maintaining identical physical dimensions, package specifications, and operating temperature ranges. The 1825HC472KAT1A offers both voltage upgrade and improved ±10% tolerance. Selection between these upgrades depends on circuit voltage requirements and tolerance specifications needed for the application.

KEMET Alternative (C1825C472MGRAC7800): This manufacturer-recommended substitute provides equivalent electrical specifications at the original 2000V rating with ±20% tolerance. The KEMET part features reduced thickness (1.55mm versus 2.54mm) and low ESL characteristics, offering potential benefits for high-frequency applications. Significantly higher inventory availability (9905 units) supports supply chain continuity.

All substitute parts are electrically and mechanically compatible with the original part's footprint and mounting requirements.

Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage-rated substitute in place of the 1825GC472MAT1A? A: Yes. The 1825HC472KAT1A (3000V), 1825HC472MAT1A (3000V), and 1825WC472KAT1A (2500V) are direct substitutes with higher voltage ratings. Higher voltage ratings do not degrade performance in lower-voltage applications and provide additional design margin.

Q: What is the difference between the KYOCERA AVX upgrades and the KEMET alternative? A: KYOCERA AVX upgrades (1825HC series) offer higher voltage ratings while maintaining the same thickness. The KEMET C1825C472MGRAC7800 provides equivalent 2000V rating but with reduced thickness (1.55mm) and low ESL features. Both are electrically compatible; selection depends on voltage requirements and physical space constraints.

Q: Are tolerance differences significant between ±10% and ±20% options? A: Tolerance selection depends on circuit requirements. The ±10% tolerance parts (1825HC472KAT1A and 1825WC472KAT1A) provide tighter capacitance control. The ±20% tolerance parts (1825GC472MAT1A, 1825HC472MAT1A, and C1825C472MGRAC7800) are suitable for general-purpose applications where wider tolerance is acceptable.

Q: Will the KEMET substitute fit in the same PCB footprint? A: Yes. The KEMET C1825C472MGRAC7800 maintains identical length and width dimensions (0.177" × 0.252"). The reduced thickness (1.55mm versus 2.54mm) provides additional clearance and does not affect footprint compatibility.

Q: Are all substitute parts RoHS and REACH compliant? A: Yes. All listed substitute parts are ROHS3 Compliant and REACH Unaffected, matching the compliance status of the original 1825GC472MAT1A.

Q: Which substitute has the best inventory availability? A: The KEMET C1825C472MGRAC7800 has the highest inventory with 9905 units in stock, compared to 2400 units for the 1825HC472KAT1A and lower quantities for other options.
