• Voltage Rating: 25V (minimum)
• Temperature Coefficient: X7R

Mechanical Requirements:

• Package / Case: 0402 (1005 Metric)
• Mounting Type: Surface Mount, MLCC
• Physical dimensions compatible with 0402 footprint

Compliance and Quality Requirements:

• AEC-Q200 automotive qualification
• ROHS3 compliance
• Moisture Sensitivity Level: 1 (Unlimited)
• Operating temperature range: -55°C to 125°C minimum

The identified substitutes meet all electrical, mechanical, and compliance requirements, enabling direct replacement in automotive and industrial applications without circuit redesign.

Engineering Selection Recommendations

AC0402KRX7R8BB472 (YAGEO)

This substitute is fully qualified for direct replacement in automotive applications. The component maintains active production status with robust inventory availability (78,020 units in stock). All electrical, mechanical, and compliance parameters are identical to the primary specification. YAGEO's AC series carries full AEC-Q200 certification and ROHS3 compliance, suitable for long-term production deployment.

CGJ2B2X7R1E472K050BA (TDK Corporation)

This substitute meets all electrical and mechanical substitution criteria with equivalent AEC-Q200 and ROHS3 compliance. However, the part has entered obsolete status, limiting future availability and long-term supply chain viability. Use this substitute only when existing inventory exists and near-term redesign is not feasible. AC0402KRX7R8BB472 is preferred for new designs and extended production runs.

Frequently Asked Questions (FAQ)

Q: Can AC0402KRX7R8BB472 be used as a direct replacement for KAM05AR71E472KH?

A: Yes. Both components share identical capacitance (4700 pF), tolerance (±10%), voltage rating (25V), temperature coefficient (X7R), package (0402), and AEC-Q200 automotive qualification. Physical dimensions and thickness specifications are within acceptable manufacturing tolerances for 0402 surface-mount packages.

Q: Why is CGJ2B2X7R1E472K050BA listed if it is obsolete?

A: CGJ2B2X7R1E472K050BA is included to acknowledge existing circuit implementations and support legacy systems. The part meets all technical substitution criteria but should not be specified for new designs due to obsolete status and declining availability.

Q: What are the critical parameters for substitution?

A: Substitution eligibility is determined by capacitance value (4700 pF), tolerance (±10%), voltage rating (25V), X7R temperature coefficient, 0402 package configuration, and AEC-Q200 automotive qualification. These parameters ensure electrical equivalence and functional interchangeability within automotive circuit designs.

Q: Are there dimensional differences between these parts?

A: Nominal differences exist within standard 0402 manufacturing tolerances. KYOCERA AVX specifies 0.040" length with 0.56mm maximum thickness, while YAGEO and TDK specify 0.039" length with 0.55mm maximum thickness. These variations fall within accepted 0402 footprint specifications and do not require PCB layout modifications.

Q: What supply chain considerations apply to these substitutes?

A: AC0402KRX7R8BB472 maintains active production status with substantial inventory (78,020 units), supporting continuous supply. CGJ2B2X7R1E472K050BA has entered obsolete status; stock depletion is expected. For long-term supply chain security, AC0402KRX7R8BB472 is the recommended substitute.
