Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KAM05AR71C472KN is determined by strict alignment of the following parameters:

Electrical Specifications: Capacitance value (4700 pF), tolerance (±10%), voltage rating (16V), and temperature coefficient (X7R) must be identical. These parameters define the component's functional behavior in the circuit.

Mechanical Compatibility: Package designation (0402 / 1005 Metric), mounting type (Surface Mount, MLCC), and physical dimensions must match to ensure compatibility with printed circuit board layouts and assembly equipment.

Environmental and Compliance Requirements: All substitute parts must maintain AEC-Q200 automotive qualification, ROHS3 compliance, and Moisture Sensitivity Level 1 rating to satisfy automotive application requirements and regulatory obligations.

Product Status Consideration: While the main part is Active, substitute parts may have different product status designations. Active status indicates ongoing manufacturer support; Obsolete status indicates discontinued production but may remain available through inventory channels.

Parameter Comparison

Engineering Selection Recommendations

KAM05AR71C472KH (KYOCERA AVX): This substitute is a parametric equivalent manufactured by the same supplier as the original component. All electrical, mechanical, and compliance specifications are identical. Product status is Active, indicating current manufacturer support. This part is suitable for direct substitution with no design modifications required.

AC0402KRX7R7BB472 (YAGEO): This substitute meets all electrical and mechanical requirements with identical capacitance, tolerance, voltage rating, temperature coefficient, and operating temperature range. Physical dimensions are equivalent within manufacturing tolerances (0.039" L vs. 0.040" L; 0.55mm thickness vs. 0.56mm thickness). AEC-Q200 automotive qualification and ROHS3 compliance are maintained. Product status is Active. This part is suitable for direct substitution.

CGJ2B2X7R1C472K050BA (TDK Corporation): This substitute meets all electrical and mechanical specifications and maintains AEC-Q200 and ROHS3 compliance. Physical dimensions are equivalent to the YAGEO substitute. Product status is Obsolete, indicating discontinued production. While inventory availability is currently high (57647 Pcs), long-term sourcing may be constrained. This part is functionally suitable for substitution but should be evaluated against long-term supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can KAM05AR71C472KH be used as a direct replacement for KAM05AR71C472KN?

A: Yes. Both parts are manufactured by KYOCERA AVX with identical electrical specifications (4700 pF, ±10%, 16V, X7R), mechanical dimensions (0402 / 1005 Metric), and compliance certifications (AEC-Q200, ROHS3). No circuit design modifications are required.

Q: What is the difference between the KYOCERA AVX and YAGEO versions?

A: Both parts meet identical electrical and compliance specifications. The primary differences are manufacturer identity and minor dimensional variations within acceptable tolerances. Physical dimensions are 0.040" L × 0.020" W (KYOCERA AVX) versus 0.039" L × 0.020" W (YAGEO), and thickness is 0.022" (0.56mm) versus 0.022" (0.55mm). These variations are within standard manufacturing tolerances and do not affect functional performance or PCB compatibility.

Q: Why is the TDK CGJ2B2X7R1C472K050BA marked as Obsolete?

A: Obsolete status indicates that TDK has discontinued production of this part number. However, inventory may remain available through distribution channels. For new designs or long-term production requirements, Active status parts (KAM05AR71C472KH or AC0402KRX7R7BB472) are recommended to ensure sustained supply chain availability.

Q: Are all substitute parts suitable for automotive applications?

A: Yes. All listed substitute parts maintain AEC-Q200 automotive qualification rating, which certifies compliance with automotive industry reliability and quality standards. All parts are ROHS3 compliant and suitable for automotive environments.

Q: What does Moisture Sensitivity Level 1 mean?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and does not require special moisture control during storage or handling. This is the lowest risk classification and simplifies inventory management and assembly logistics.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. All substitute parts are electrically and mechanically equivalent. No PCB layout modifications, schematic changes, or assembly process adjustments are required. Parts can be substituted at the component level without design review.

Q: What should be considered when selecting between available substitutes?

A: Selection should be based on: (1) Product Status—Active parts ensure ongoing manufacturer support; (2) Inventory Availability—current stock levels and supply chain reliability; (3) Manufacturer Preference—if design documentation specifies preferred suppliers; (4) Cost and Lead Time—factors determined by current market conditions and distribution channels.
