1825GC103MAT1A Equivalent & Substitute Parts

Part Overview

The 1825GC103MAT1A is a high-voltage ceramic capacitor manufactured by KYOCERA AVX with a capacitance of 10000 pF, rated voltage of 2000V (2kV), and X7R temperature coefficient. This surface-mount multilayer ceramic capacitor (MLCC) in 1825 (4564 Metric) package is designed for general-purpose applications requiring high-voltage performance. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Substitute parts are identified when equivalent electrical and mechanical parameters are maintained or enhanced while preserving package compatibility and operational specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 1825GC103MAT1A is determined by strict adherence to the following electrical and mechanical parameters:

• Capacitance: Must remain 10000 pF
• Temperature Coefficient: Must remain X7R
• Package / Case: Must remain 1825 (4564 Metric)
• Mounting Type: Must remain Surface Mount, MLCC
• Physical Dimensions: Must match 0.177" L x 0.252" W (4.50mm x 6.40mm) and 0.100" (2.54mm) maximum thickness
• Operating Temperature Range: Must maintain -55°C ~ 125°C
• RoHS Status: Must maintain ROHS3 Compliance
• Moisture Sensitivity Level: Must maintain MSL 1

Substitute parts may vary in tolerance (±10% vs ±20%) and rated voltage (2000V, 3000V) while maintaining all other parameters. Tighter tolerance and higher voltage ratings represent functional improvements without compromising compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain full compatibility with the 1825GC103MAT1A in terms of package, mounting, and thermal specifications. Selection between alternatives is based on application requirements:

1825GC103KAT1A provides improved tolerance specification (±10% versus ±20%) while maintaining identical voltage rating (2000V) and all mechanical parameters. This part is suitable for applications requiring tighter capacitance accuracy.

1825HC103KAT1A provides both improved tolerance (±10%) and elevated voltage rating (3000V versus 2000V). This part is suitable for applications requiring higher voltage margin or operation in elevated voltage environments while maintaining the same physical footprint and thermal characteristics.

All three parts are ROHS3 compliant, carry MSL 1 rating, and are currently in active production status.

Frequently Asked Questions (FAQ)

Q: Can 1825GC103KAT1A be used as a direct replacement for 1825GC103MAT1A?

A: Yes. Both parts share identical capacitance (10000 pF), voltage rating (2000V), temperature coefficient (X7R), package (1825), and physical dimensions. The 1825GC103KAT1A offers tighter tolerance (±10% versus ±20%), making it functionally compatible and suitable for direct substitution.

Q: What is the difference between 1825GC103KAT1A and 1825HC103KAT1A?

A: The primary difference is rated voltage: 1825GC103KAT1A is rated 2000V while 1825HC103KAT1A is rated 3000V. Both share 10000 pF capacitance, ±10% tolerance, X7R temperature coefficient, and identical physical dimensions. The higher voltage rating of 1825HC103KAT1A provides additional voltage margin without changing package or mounting characteristics.

Q: Are all three parts in the same physical package?

A: Yes. All three parts use the 1825 (4564 Metric) package with dimensions of 0.177" L x 0.252" W (4.50mm x 6.40mm) and maximum thickness of 0.100" (2.54mm). They are mechanically and electrically interchangeable from a PCB layout perspective.

Q: Do these parts have the same moisture sensitivity level?

A: Yes. All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All three parts are ROHS3 compliant and carry REACH Unaffected status.
