2225AC683KAT1A Equivalent & Substitute Parts

Part Overview

The 2225AC683KAT1A is a 0.068 µF ceramic capacitor rated at 1000V (1kV) with X7R temperature coefficient, manufactured by KYOCERA AVX in 2225 (5763 Metric) package format. 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 ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified for applications requiring alternative sourcing, higher voltage ratings, or extended temperature performance.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2225AC683KAT1A are qualified based on the following critical parameters:

• Capacitance Value: Must be 0.068 µF ±10%
• Temperature Coefficient: Must be X7R for stable performance across the operating range
• Package Format: Must be 2225 (5763 Metric) for mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount MLCC
• Voltage Rating: Equal to or greater than 1000V (1kV)
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity: MSL 1 (Unlimited)

Two substitute parts meet these criteria:

1. 2225SC683KAT1A (KYOCERA AVX): Upgrade option with 1500V (1.5kV) rating, same manufacturer, identical mechanical dimensions, higher voltage capability for demanding applications.

2. VJ2225Y683KXGAT (Vishay Vitramon): Direct equivalent with 1000V (1kV) rating, extended operating temperature to 150°C, alternative manufacturer sourcing.

Engineering Selection Recommendations

2225SC683KAT1A (KYOCERA AVX Upgrade)

Select this part when circuit design margins require higher voltage headroom. The 1500V rating provides 50% additional voltage capability over the main part while maintaining identical capacitance, tolerance, temperature coefficient, and physical dimensions. Both parts are manufactured by KYOCERA AVX, ensuring consistent quality and supply chain continuity. ROHS3 compliance and MSL 1 rating are maintained.

VJ2225Y683KXGAT (Vishay Vitramon Direct)

Select this part for alternative manufacturer sourcing or when extended upper operating temperature to 150°C is required. The 1000V rating matches the main part specification. Physical dimensions are within acceptable tolerance (length 5.59mm vs. 5.72mm, thickness 2.18mm vs. 2.54mm). ROHS3 compliance and MSL 1 rating are maintained. All three parts share identical electrical specifications for capacitance, tolerance, and temperature coefficient.

Frequently Asked Questions (FAQ)

Q: Can 2225SC683KAT1A be used as a direct replacement for 2225AC683KAT1A?

A: Yes. The 2225SC683KAT1A is a direct mechanical and electrical substitute with identical capacitance (0.068 µF), tolerance (±10%), temperature coefficient (X7R), and package dimensions (2225). The higher voltage rating (1500V vs. 1000V) provides additional design margin without affecting circuit performance.

Q: What is the difference between the main part and VJ2225Y683KXGAT?

A: Both parts have identical electrical specifications: 0.068 µF capacitance, ±10% tolerance, X7R temperature coefficient, and 1000V voltage rating. The primary differences are manufacturer (Vishay Vitramon vs. KYOCERA AVX), extended operating temperature range (150°C vs. 125°C upper limit), and minor physical dimension variations within acceptable tolerance.

Q: Are all three parts interchangeable on the PCB?

A: Yes. All three parts use the same 2225 (5763 Metric) package format and Surface Mount MLCC mounting type. PCB footprints and reflow profiles are compatible across all three parts.

Q: Do all substitute parts maintain RoHS3 compliance?

A: Yes. Both 2225SC683KAT1A and VJ2225Y683KXGAT are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the main part specification.

Q: Which part should be selected for high-temperature applications?

A: VJ2225Y683KXGAT supports operating temperatures up to 150°C, compared to 125°C for both KYOCERA AVX parts. Select this part if the application requires extended upper temperature performance.

Q: What is the basis for substitution compatibility?

A: Substitution is based on matching capacitance value (0.068 µF), tolerance (±10%), temperature coefficient (X7R), package format (2225), mounting type (Surface Mount MLCC), and compliance certifications (ROHS3, MSL 1). Voltage rating must be equal to or greater than the original specification.
