Capacitance: 10000 pF (exact match required)
Package / Case: 1825 (4564 Metric) (exact match required)
Temperature Coefficient: X7R (exact match required)
Operating Temperature Range: -55°C ~ 125°C (exact match required)
Mounting Type: Surface Mount, MLCC (exact match required)

Allowable Variation Parameters:

Voltage - Rated: Substitutes may have equal or higher voltage ratings (1500V, 2000V, or 3000V)
Tolerance: Substitutes may have tighter tolerance (±10% vs. ±20%)

The substitute parts 1825GC103KAT1A, 1825HC103KAT1A, and 1825SC103KAT1A maintain identical capacitance, package dimensions, and temperature characteristics while offering improved voltage ratings and tolerance specifications. All substitute parts are manufactured by KYOCERA AVX and maintain full compliance with RoHS3 and REACH standards.

Frequently Asked Questions (FAQ)

Q: Can 1825GC103KAT1A or 1825HC103KAT1A be used as direct replacements for 1825SC103MAT3A?

A: Yes. Both parts maintain identical capacitance (10000 pF), package dimensions (1825/4564 Metric), temperature coefficient (X7R), and operating temperature range (-55°C ~ 125°C). The higher voltage ratings (2000V and 3000V respectively) are compatible with circuits designed for 1500V operation.

Q: What is the difference between 1825SC103MAT3A and 1825SC103KAT1A?

A: Both parts share identical electrical specifications (10000 pF, 1500V, X7R, -55°C ~ 125°C) and package form factor (1825). The primary difference is tolerance: 1825SC103MAT3A has ±20% tolerance while 1825SC103KAT1A has ±10% tolerance. The packaging format differs (bulk vs. Tape & Reel).

Q: Are all substitute parts available in the same packaging format?

A: The main part 1825SC103MAT3A is supplied in bulk packaging. All substitute parts (1825GC103KAT1A, 1825HC103KAT1A, 1825SC103KAT1A) are supplied in Tape & Reel (TR) format, which is standard for high-volume surface-mount assembly.

Q: Do substitute parts meet the same compliance standards?

A: Yes. All substitute parts are ROHS3 Compliant, REACH Unaffected, and carry Moisture Sensitivity Level 1 (Unlimited), matching the original part's compliance profile.

Q: Which substitute part offers the best inventory availability?

A: 1825HC103KAT1A has the highest inventory at 25145 units in stock, followed by 1825GC103KAT1A at 2400 units and 1825SC103KAT1A at 1356 units.
