2225AC154MAT1A Equivalent & Substitute Parts

Part Overview

The 2225AC154MAT1A is a 0.15 µF ceramic capacitor rated for 1000V (1kV) 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 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 to support procurement flexibility, design redundancy, and supply chain continuity.

Substitute Part Grouping Explanation

Substitution of the 2225AC154MAT1A is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 0.15 µF (exact match required)
• Voltage Rating: 1000V minimum (equal or higher acceptable)
• Temperature Coefficient: X7R (ensures stable performance across -55°C to 125°C)
• Package / Case: 2225 (5763 Metric) form factor (ensures mechanical and electrical compatibility)
• Mounting Type: Surface Mount, MLCC (maintains assembly process compatibility)
• Compliance: ROHS3 and REACH status alignment

The substitute part C2225C154KDRAC7800 (KEMET) meets all critical substitution criteria. Tolerance variation (±20% vs. ±10%) represents an upgrade in capacitance accuracy and does not prevent substitution. Physical dimensions remain within acceptable tolerances for the 2225 package class.

Parameter Comparison

Engineering Selection Recommendations

Both the 2225AC154MAT1A and C2225C154KDRAC7800 are active production parts with full ROHS3 compliance and REACH unaffected status. Selection between these parts is based on:

• Procurement Availability: Choose based on current inventory and lead time requirements. KYOCERA AVX part has 4400 units in stock; KEMET part has 1215 units in stock.
• Tolerance Requirements: The KEMET substitute offers tighter tolerance (±10% vs. ±20%), suitable for applications requiring higher capacitance accuracy.
• Packaging Format: KEMET part is supplied in Tape & Reel format, optimized for automated assembly processes.
• Physical Fit: Both parts fit the 2225 package class with minor dimensional variations within acceptable tolerances for standard PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can C2225C154KDRAC7800 directly replace 2225AC154MAT1A in existing designs?

A: Yes. Both parts share identical capacitance (0.15 µF), voltage rating (1000V), temperature coefficient (X7R), and package form factor (2225). Physical dimensions are within acceptable tolerances for standard PCB footprints. No design changes are required.

Q: What is the significance of the tolerance difference (±20% vs. ±10%)?

A: Tolerance defines the acceptable range of actual capacitance around the nominal value. The KEMET substitute with ±10% tolerance provides tighter capacitance accuracy. This is an upgrade that does not prevent substitution; applications tolerating ±20% will also accept ±10%.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and rated for unlimited moisture sensitivity (MSL 1). Compliance status is equivalent.

Q: Does the slight thickness difference (2.54mm vs. 2.70mm) affect PCB assembly?

A: No. Both parts conform to the 2225 (5763 Metric) package class specification. The 0.16mm thickness variation is within standard PCB design tolerances and does not affect placement, soldering, or clearance requirements.

Q: What is the difference between the packaging formats?

A: The KYOCERA AVX part uses standard packaging; the KEMET substitute is supplied in Tape & Reel (TR) format, which is optimized for high-volume automated assembly and reduces handling time in production environments.
