Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMK063BJ474MP-F is determined by strict equivalence in the following parameters:

Critical Parameters (Must Match):

• Capacitance: 0.47 µF
• Temperature Coefficient: X5R
• Package / Case: 0201 (0603 Metric)
• Mounting Type: Surface Mount, MLCC
• Operating Temperature Range: -55°C ~ 85°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variations:

• Voltage Rating: Substitute parts rated at 6.3V or higher are acceptable, as they provide equal or greater voltage margin in circuits designed for 4V operation
• Tolerance: ±10% tolerance is acceptable as a tighter specification than the original ±20%
• Packaging Format: Tape & Reel (TR) and Cut Tape (CT) formats are interchangeable in manufacturing environments
• Thickness: Minor variations within the 0.30mm to 0.39mm range are acceptable provided they do not exceed board assembly constraints

Substitute parts are grouped by voltage rating and tolerance to facilitate selection based on design requirements and availability.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Electrical Characteristics):

JMK063BJ474MP-F (Taiyo Yuden) provides direct functional equivalence with identical capacitance, tolerance, and temperature coefficient. The 6.3V rating provides increased voltage margin. However, this part retains "Not For New Designs" status, limiting its suitability for long-term production continuity.

For Active Production and Long-Term Availability:

C0603X5R1A474M030BC (TDK Corporation) is designated as Active product status, ensuring ongoing manufacturing and supply chain support. This part meets all critical parameters with 10V voltage rating and includes Low ESL feature specification. This selection is appropriate for designs requiring sustained component availability and compliance with active product portfolios.

For Tighter Tolerance Requirements:

CL03A474KQ3NNNH and CL03A474KQ3NNNC (Samsung Electro-Mechanics) both provide ±10% tolerance, representing improved capacitance accuracy compared to the original ±20% specification. Both are Active status with extensive inventory availability (12,220 and 3,247,817 units respectively). These parts are suitable for applications where capacitance tolerance is a critical design parameter.

For Tolerance-Matched Substitution:

CL03A474MQ3NNNH and CL03A474MQ3NNNC (Samsung Electro-Mechanics) maintain ±20% tolerance matching the original specification while providing 6.3V rating and Active product status. These selections preserve original design intent while ensuring production continuity.

All substitute parts comply with ROHS3 and maintain Moisture Sensitivity Level 1 (Unlimited), ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can I substitute the AMK063BJ474MP-F with a higher voltage-rated capacitor?

A: Yes. Substitute parts rated at 6.3V or 10V are acceptable in circuits designed for 4V operation. Higher voltage ratings provide additional safety margin and do not degrade circuit performance. The electrical characteristics (capacitance, temperature coefficient, tolerance) remain the controlling factors for functional equivalence.

Q: What is the difference between ±10% and ±20% tolerance specifications?

A: Tolerance defines the allowable deviation of actual capacitance from the nominal value. ±10% tolerance (CL03A474KQ3NNNH, CL03A474KQ3NNNC) provides tighter capacitance accuracy than ±20% (original and alternative parts). Selection depends on circuit requirements; applications sensitive to capacitance variation benefit from ±10% parts, while general-purpose filtering applications accept ±20% tolerance.

Q: Are Tape & Reel and Cut Tape packaging formats interchangeable?

A: Yes. Both packaging formats contain identical components and differ only in presentation for automated assembly equipment. Tape & Reel (TR) and Cut Tape (CT) formats are interchangeable from an electrical and mechanical standpoint. Equipment compatibility should be verified with manufacturing process specifications.

Q: Why is the original AMK063BJ474MP-F marked "Not For New Designs"?

A: "Not For New Designs" status indicates the component has reached end-of-life and is no longer recommended for new product development. Existing inventory remains available for legacy system support and production continuity. For new designs, Active status parts such as C0603X5R1A474M030BC or Samsung CL series components are appropriate selections.

Q: What does X5R temperature coefficient mean?

A: X5R is a standardized temperature coefficient classification indicating capacitance variation of ±15% across the operating temperature range of -55°C to +85°C. This specification ensures stable capacitor performance across industrial temperature extremes and is suitable for general-purpose and filtering applications.

Q: Can I use C0603X5R1A474M030BC as a direct replacement?

A: Yes. C0603X5R1A474M030BC meets all critical electrical parameters (0.47 µF, X5R, 0201 package, -55°C to +85°C operating range) and provides superior product status (Active). The 10V rating exceeds the original 4V requirement, and the Low ESL feature provides additional performance benefit. This part is suitable for direct substitution with enhanced long-term availability assurance.

Q: What is Moisture Sensitivity Level 1?

A: Moisture Sensitivity Level (MSL) 1 indicates unlimited shelf life without moisture exposure precautions. Components with MSL 1 do not require special drying or storage protocols and can be stored under standard warehouse conditions indefinitely. All listed substitute parts maintain MSL 1 compatibility.

Q: Are there physical dimension differences between substitute parts?

A: All substitute parts maintain the 0201 (0603 Metric) package format with identical length and width (0.024" L x 0.012" W / 0.60mm x 0.30mm). Thickness varies slightly between 0.013" to 0.015" (0.33mm to 0.39mm), which is within standard PCB assembly tolerances and does not affect mounting or performance.
