2225AC683MAT3A\SB Ceramic Capacitor Equivalent & Substitute Parts

Part Overview

The 2225AC683MAT3A\SB is a high-voltage ceramic capacitor manufactured by KYOCERA AVX, rated at 0.068 µF capacitance with 1000V (1kV) voltage rating and X7R temperature coefficient. This surface-mount multilayer ceramic capacitor (MLCC) in 2225 package form factor is designed for general-purpose applications requiring stable performance across the -55°C to 125°C operating temperature range. The part maintains active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical performance can be achieved through alternative manufacturers or upgraded specifications that maintain backward compatibility within the application circuit requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2225AC683MAT3A\SB is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance value: 0.068 µF (exact match required)
• Package / Case: 2225 (5763 Metric) form factor
• Mounting type: Surface Mount, MLCC
• Temperature coefficient: X7R
• Operating temperature range: -55°C to 125°C minimum
• Physical dimensions: Compatible with 2225 package specifications

Allowable Variation Parameters:

• Voltage rating: Equal to or greater than 1000V
• Tolerance: ±20% or tighter (lower tolerance values are acceptable upgrades)
• Manufacturer: Alternative qualified manufacturers permitted
• Packaging format: Tape & Reel or bulk packaging acceptable

The identified substitute part 2225SC683KAT1A meets all mandatory matching criteria while providing upgraded voltage rating (1500V vs. 1000V) and improved tolerance (±10% vs. ±20%), making it suitable for direct replacement in applications where the original part is unavailable or where enhanced voltage margin is beneficial.

Parameter Comparison

Engineering Selection Recommendations

Both the 2225AC683MAT3A\SB and 2225SC683KAT1A are active products from KYOCERA AVX with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on application voltage requirements and tolerance specifications:

The 2225AC683MAT3A\SB is appropriate for applications with 1000V maximum voltage stress and where ±20% capacitance tolerance is acceptable within circuit design margins.

The 2225SC683KAT1A provides upgraded performance through 1500V voltage rating and ±10% capacitance tolerance, offering enhanced reliability margin and tighter capacitance control. This substitute is suitable for direct replacement in any application originally specified for the main part, with the additional benefit of higher voltage headroom and improved tolerance characteristics.

Both parts share identical physical dimensions, mounting characteristics, and thermal operating range, ensuring mechanical and thermal compatibility in PCB assembly and operational environments.

Frequently Asked Questions (FAQ)

Q: Can 2225SC683KAT1A replace 2225AC683MAT3A\SB in existing designs?

A: Yes. The substitute part maintains identical capacitance (0.068 µF), package form factor (2225), mounting type (surface mount MLCC), temperature coefficient (X7R), and operating temperature range (-55°C to 125°C). The upgraded voltage rating (1500V vs. 1000V) and improved tolerance (±10% vs. ±20%) are backward compatible with applications designed for the original part.

Q: What are the key differences between these two parts?

A: The primary differences are voltage rating (1000V main part vs. 1500V substitute) and capacitance tolerance (±20% vs. ±10%). Both parts are manufactured by KYOCERA AVX in identical 2225 packages with matching physical dimensions and thermal characteristics.

Q: Are there packaging format differences?

A: The main part 2225AC683MAT3A\SB uses standard packaging, while the substitute 2225SC683KAT1A is supplied in Tape & Reel (TR) format. Both formats are compatible with automated PCB assembly processes.

Q: Do these parts have different moisture sensitivity requirements?

A: No. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity precautions are required during storage or handling.

Q: Are both parts RoHS compliant?

A: Yes. Both 2225AC683MAT3A\SB and 2225SC683KAT1A are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
