Substitute Part Grouping Explanation

Substitution eligibility for the 2225AC104MAT1A is determined by strict equivalence in the following critical parameters:

• Capacitance Value: Must be 0.1 µF (no deviation)
• Voltage Rating: Must be 1000V (1kV) or higher
• Temperature Coefficient: Must be X7R (ensures stable capacitance across operating temperature range)
• Package / Case: Must be 2225 (5763 Metric) for mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount, MLCC
• Operating Temperature Range: Must support -55°C to 125°C minimum
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

The substitute part 2225AC104KAT1A meets all these criteria. The primary difference is the capacitance tolerance grade: the main part specifies ±20% tolerance, while the substitute offers ±10% tolerance. This represents an upgrade in tolerance performance, making the substitute suitable for applications where tighter capacitance control is beneficial or required.

Parameter Comparison

Engineering Selection Recommendations

Both the 2225AC104MAT1A and 2225AC104KAT1A are active production parts from KYOCERA AVX with full ROHS3 compliance and MSL 1 rating, ensuring regulatory compliance and unlimited shelf life under standard storage conditions.

The 2225AC104KAT1A offers superior tolerance performance at ±10% compared to the ±20% tolerance of the main part, while maintaining identical electrical and mechanical specifications. This substitute is suitable for direct replacement in applications where the tighter tolerance is acceptable or advantageous. The substitute also provides significantly higher inventory availability (3420 units versus 829 units), supporting supply chain continuity.

Selection between these parts should be based on tolerance requirements specific to the application circuit. If ±20% tolerance is sufficient, either part is acceptable. If ±10% tolerance is required or preferred, the 2225AC104KAT1A is the appropriate choice.

Frequently Asked Questions (FAQ)

Q: Can 2225AC104KAT1A be used as a direct replacement for 2225AC104MAT1A?

A: Yes. Both parts are electrically and mechanically identical except for capacitance tolerance. The substitute features tighter ±10% tolerance versus the main part's ±20% tolerance. This represents an upgrade in performance and is compatible with all applications designed for the original part.

Q: What is the significance of the tolerance difference?

A: Tolerance defines the acceptable range of actual capacitance values around the nominal 0.1 µF specification. The main part allows ±20% deviation (0.08 µF to 0.12 µF), while the substitute allows ±10% deviation (0.09 µF to 0.11 µF). Tighter tolerance provides more predictable circuit behavior in applications sensitive to capacitance variation.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 2225 (5763 Metric) package with identical dimensions: 5.72mm length, 6.35mm width, and 2.54mm maximum thickness. They are mechanically interchangeable on PCBs designed for this package.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, ensuring compliance with environmental regulations and unlimited shelf life under standard storage conditions.

Q: Which part should be selected for new designs?

A: For new designs, the 2225AC104KAT1A is recommended due to superior tolerance performance and higher inventory availability. The ±10% tolerance provides better circuit predictability without cost or performance penalties.
