Key Parameters

Substitute Part Grouping Explanation

Substitution logic is based on the following critical parameters that must remain constant across all equivalent parts:

• Capacitance: 4700 pF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating: 100V (exact match required)
• Package: 0603 (1608 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Temperature Coefficient: X7R (primary equivalents) or X8R (upgrade option)
• Operating Temperature: -55°C ~ 125°C minimum (X7R) or -55°C ~ 150°C (X8R upgrade)
• Soft Termination: Required feature
• AEC-Q200: Required automotive qualification
• RoHS3 Compliance: Required
• MSL 1: Required

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and full compliance with ROHS3, REACH Unaffected, and AEC-Q200 automotive qualification standards. Selection among direct equivalents is based on availability, lead time, and thickness constraints within the allowed 0.031" to 0.037" range.

The upgrade option CGA3E2X8R2A472K080AE (X8R) provides extended operating temperature capability to 150°C while maintaining all other electrical and mechanical specifications. This upgrade is suitable for applications requiring enhanced thermal stability beyond the standard -55°C ~ 125°C range.

Thickness variation across manufacturers (0.031" to 0.037") must be evaluated against PCB layout constraints and assembly process requirements. All parts are qualified for soft termination and automotive boardflex-sensitive applications.

Frequently Asked Questions (FAQ)

Q: Can I substitute the KAF15AR72A472KT with any of the listed parts? A: Yes. All direct equivalent parts (KEMET, TDK X7R, Murata, Samsung) are electrically and mechanically interchangeable. They share identical capacitance, tolerance, voltage rating, temperature coefficient, package, and automotive qualification.

Q: What is the difference between X7R and X8R temperature coefficients? A: X7R maintains capacitance within ±15% across -55°C ~ 125°C. X8R maintains capacitance within ±15% across -55°C ~ 150°C. The X8R upgrade (CGA3E2X8R2A472K080AE) extends the upper operating temperature limit by 25°C while maintaining the same capacitance and voltage rating.

Q: Does thickness variation affect compatibility? A: Thickness ranges from 0.031" (Murata) to 0.037" (KEMET, TDK X7R). Verify PCB layout and assembly clearances. All thicknesses are within standard 0603 package specifications and do not affect electrical performance.

Q: Are all substitute parts AEC-Q200 qualified? A: Yes. All listed parts carry AEC-Q200 automotive qualification and are suitable for automotive and boardflex-sensitive applications.

Q: What is MSL 1 and why does it matter? A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture baking requirements. All listed parts have MSL 1, eliminating moisture management concerns during storage and assembly.

Q: Can I use the X8R upgrade in place of the original X7R part? A: Yes. The X8R upgrade maintains the same capacitance, tolerance, and voltage rating while providing extended temperature range. It is a direct functional upgrade with no negative impact on circuit performance.
