Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1825GC103MAT1A are qualified based on the following criteria:

Maintained Parameters (Required for Substitution):

• Capacitance value: 10000 pF
• Temperature coefficient: X7R
• Package / Case: 1825 (4564 Metric)
• Mounting type: Surface Mount, MLCC
• Physical dimensions: 0.177" L x 0.252" W (4.50mm x 6.40mm)
• Operating temperature range: -55°C ~ 125°C
• RoHS3 compliance and MSL rating

Allowed Variation Parameters:

• Tolerance: May be tighter (±10% acceptable as upgrade)
• Voltage rating: May be equal or higher (2kV or greater acceptable)
• Packaging format: Tape & Reel (TR) acceptable as alternative to standard packaging

Two substitute parts meet these criteria:

1. 1825GC103KAT1A – Tighter tolerance upgrade (±10% vs ±20%), same voltage rating (2kV)
2. 1825HC103KAT1A – Tighter tolerance upgrade (±10% vs ±20%), higher voltage rating (3kV vs 2kV)

Parameter Comparison

Engineering Selection Recommendations

1825GC103KAT1A Selection Criteria:

• Select when tighter capacitance tolerance (±10%) is required without increasing voltage margin
• Equivalent voltage rating (2kV) maintains original circuit design specifications
• All three parts are Active status with ROHS3 compliance and unlimited MSL rating
• Tape & Reel packaging format is suitable for automated assembly processes

1825HC103KAT1A Selection Criteria:

• Select when higher voltage margin (3kV vs 2kV) is required for enhanced reliability
• Tighter tolerance (±10%) provides improved capacitance accuracy
• Higher voltage rating does not degrade performance in 2kV-rated circuits
• All three parts are Active status with ROHS3 compliance and unlimited MSL rating
• Tape & Reel packaging format is suitable for automated assembly processes

All substitute parts maintain identical physical dimensions, operating temperature range, and compliance certifications as the main part.

Frequently Asked Questions (FAQ)

Q: Can 1825GC103KAT1A directly replace 1825GC103MAT1A? A: Yes. Both parts have identical capacitance (10000 pF), voltage rating (2kV), temperature coefficient (X7R), package (1825), and physical dimensions. The substitute has tighter tolerance (±10% vs ±20%), which is an improvement. Packaging format differs (Tape & Reel vs standard), but this does not affect electrical compatibility.

Q: Can 1825HC103KAT1A directly replace 1825GC103MAT1A? A: Yes. Both parts have identical capacitance (10000 pF), temperature coefficient (X7R), package (1825), and physical dimensions. The substitute has higher voltage rating (3kV vs 2kV) and tighter tolerance (±10% vs ±20%). Higher voltage rating provides additional safety margin in 2kV-rated circuits without performance degradation.

Q: What is the difference between ±20% and ±10% tolerance? A: Tolerance specifies the allowable deviation from the nominal capacitance value. ±20% tolerance allows capacitance to range from 8000 pF to 12000 pF. ±10% tolerance narrows this range to 9000 pF to 11000 pF. Tighter tolerance (±10%) provides more precise capacitance values for circuits requiring higher accuracy.

Q: Are all three parts suitable for automated assembly? A: Yes. All three parts are Surface Mount, MLCC components in 1825 (4564 Metric) package with identical physical dimensions (0.177" L x 0.252" W, 0.100" max thickness). The substitute parts are supplied in Tape & Reel format, which is standard for automated pick-and-place assembly.

Q: Do all parts meet the same compliance standards? A: Yes. All three parts are ROHS3 Compliant, REACH Unaffected, with Moisture Sensitivity Level 1 (Unlimited). All parts are classified as Active product status.

Q: What is the voltage derating consideration when using 1825HC103KAT1A in a 2kV circuit? A: The 1825HC103KAT1A is rated for 3kV, which exceeds the 2kV circuit requirement. This provides a 50% voltage safety margin (2kV operating / 3kV rated = 0.67 derating factor), enhancing component reliability and circuit robustness.
