2225SC683MAT1A Equivalent & Substitute Parts

Part Overview

The 2225SC683MAT1A is a 0.068 µF ceramic capacitor rated for 1500V (1.5kV) with X7R temperature coefficient, manufactured by KYOCERA AVX. This high-voltage surface-mount multilayer ceramic capacitor (MLCC) is designed for general-purpose applications requiring stable capacitance across a wide temperature range (-55°C to 125°C). The part is ROHS3 compliant and carries MSL 1 rating, indicating unlimited moisture sensitivity protection. Finding equivalent or substitute parts becomes necessary when managing inventory constraints, lead time optimization, or sourcing flexibility across multiple suppliers.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 2225SC683MAT1A is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 0.068 µF (exact match required)
• Voltage Rating: 1500V minimum (1.5kV)
• Temperature Coefficient: X7R (ensures stable performance across -55°C to 125°C)
• Package / Case: 2225 (5763 Metric) form factor
• Mounting Type: Surface Mount, MLCC
• Compliance: ROHS3 and REACH Unaffected status

The two identified substitute parts meet all critical electrical and mechanical parameters. Tolerance differences (±20% vs. ±10%) represent an upgrade path where tighter tolerance specifications are available from the same or alternative manufacturers. Both substitute parts maintain identical voltage ratings, temperature coefficients, package dimensions, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

2225SC683KAT1A (KYOCERA AVX): This substitute offers tighter tolerance (±10% vs. ±20%) while maintaining identical electrical specifications and package dimensions. Both parts are manufactured by KYOCERA AVX, ensuring consistent quality and reliability. This option is suitable for applications where tolerance improvement is beneficial without requiring supplier diversification.

C2225C683KFRAC7800 (KEMET): This substitute provides cross-manufacturer compatibility with tighter tolerance (±10%) and documented low ESL characteristics. Dimensional variations are minimal (0.220" L x 0.252" W vs. 0.225" L x 0.250" W; thickness 0.106" vs. 0.100"), remaining within typical PCB layout tolerances for 2225 package footprints. All compliance certifications (ROHS3, REACH Unaffected) are maintained. This option is suitable for applications requiring supplier diversification or when KEMET supply chain availability is preferred.

Both substitutes maintain full electrical and mechanical compatibility with the original 2225SC683MAT1A specification.

Frequently Asked Questions (FAQ)

Q: Can 2225SC683KAT1A replace 2225SC683MAT1A directly? A: Yes. Both parts share identical capacitance (0.068 µF), voltage rating (1500V), temperature coefficient (X7R), package (2225), and operating temperature range (-55°C to 125°C). The primary difference is tolerance: 2225SC683KAT1A offers ±10% versus ±20% on the original part. This represents an upgrade in precision with no electrical or mechanical incompatibility.

Q: What are the dimensional differences between C2225C683KFRAC7800 and the original part? A: Length differs by 0.005" (5.60mm vs. 5.72mm), width by 0.002" (6.40mm vs. 6.35mm), and thickness by 0.006" (2.70mm vs. 2.54mm). These variations fall within standard PCB layout tolerances for 2225 package footprints and do not affect electrical performance or board assembly compatibility.

Q: Are all three parts ROHS3 compliant? A: Yes. The main part 2225SC683MAT1A and both substitutes (2225SC683KAT1A and C2225C683KFRAC7800) are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What does MSL 1 rating mean for these capacitors? A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited moisture sensitivity protection. These parts require no special moisture control during storage, handling, or assembly, simplifying logistics and manufacturing processes.

Q: Can I use C2225C683KFRAC7800 in a design originally specified for 2225SC683MAT1A? A: Yes. The KEMET part C2225C683KFRAC7800 meets all critical electrical parameters (0.068 µF, 1500V, X7R, -55°C to 125°C) and maintains 2225 package compatibility. Minor dimensional variations are within standard PCB design tolerances. Verify PCB layout clearances if space constraints are critical.

Q: What is the difference between ±20% and ±10% tolerance? A: Tolerance specifies the allowable deviation from the nominal capacitance value. ±20% allows deviation from 0.0544 µF to 0.0816 µF, while ±10% restricts deviation to 0.0612 µF to 0.0748 µF. Applications requiring tighter capacitance control benefit from the ±10% substitute parts.
