AMK063ABJ105MP-F Equivalent & Substitute Parts

Part Overview

The AMK063ABJ105MP-F is a 1 µF ceramic capacitor manufactured by Taiyo Yuden, rated for 4V operation with X5R temperature coefficient characteristics. This multilayer ceramic capacitor (MLCC) is packaged in 0201 (0603 Metric) form factor and is designed for surface mount applications, particularly in SMPS filtering circuits.

The AMK063ABJ105MP-F carries a "Not For New Designs" product status. Identifying equivalent and substitute parts is necessary to support existing designs, facilitate procurement alternatives, and ensure design continuity when the primary part becomes unavailable or reaches end-of-life status.

Substitute Part Grouping Explanation

Substitution of the AMK063ABJ105MP-F is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters for Direct Substitution:

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

Parameters Allowing Variation:

Voltage Rating: Substitutes with equal or higher voltage ratings are acceptable
Tolerance: Substitutes with equal or tighter tolerance are acceptable
Thickness: Minor variations within manufacturing tolerances are acceptable
Manufacturer: Different manufacturers are acceptable provided all critical parameters match

Substitute parts are grouped into two categories:

Direct Equivalents: Parts with identical voltage rating (4V) and tolerance (±20%) to the main part.

Upgrades: Parts with higher voltage ratings (6.3V or 10V) or tighter tolerance (±10%) that maintain all other critical parameters, providing enhanced performance margins.

Engineering Selection Recommendations

Direct Equivalents (4V, ±20% Tolerance):

CC0201MRX5R4BB105 (YAGEO) and CL03A105MR3CSNC / CL03A105MR3CSNH (Samsung Electro-Mechanics) provide direct electrical equivalence to the AMK063ABJ105MP-F. These parts maintain identical voltage rating and tolerance specifications. YAGEO and Samsung Electro-Mechanics parts carry Active product status, ensuring ongoing availability and manufacturing support. All direct equivalents are ROHS3 compliant with MSL 1 rating.

Upgrade Options (Higher Voltage Rating):

JMK063ABJ105MP-F (Taiyo Yuden, 6.3V), CL03A105MQ3CSNC / CL03A105MQ3CSNH (Samsung Electro-Mechanics, 6.3V), and CL03A105MP3NSNC (Samsung Electro-Mechanics, 10V) provide higher voltage margins while maintaining 1 µF capacitance and X5R temperature coefficient. These upgrades are suitable for applications requiring enhanced voltage headroom. CL03A105KQ3CSNC and CL03A105KQ3CSNH (Samsung Electro-Mechanics, 6.3V) additionally offer tighter ±10% tolerance specification. All upgrade options carry Active product status.

Upgrade Option (Highest Voltage Rating):

KGM03BR50J105MH (KYOCERA AVX, 6.3V) provides an alternative upgrade path with Active product status and established supply chain presence.

All substitute parts maintain the required -55°C ~ 85°C operating temperature range, MSL 1 moisture sensitivity rating, and ROHS3 compliance. Selection between direct equivalents and upgrades depends on circuit voltage margin requirements and procurement availability.

Frequently Asked Questions (FAQ)

Q: Can I use a 6.3V rated capacitor in place of the 4V AMK063ABJ105MP-F?

A: Yes. Higher voltage-rated capacitors are electrically compatible substitutes. A 6.3V capacitor operates safely in a 4V circuit and provides additional voltage margin. The 1 µF capacitance, X5R temperature coefficient, and physical dimensions remain identical.

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

A: Tolerance defines the allowable deviation from the nominal 1 µF capacitance value. ±20% tolerance allows capacitance between 0.8 µF and 1.2 µF. ±10% tolerance allows capacitance between 0.9 µF and 1.1 µF. Tighter tolerance (±10%) provides more precise capacitance values and is suitable for applications requiring stricter performance specifications.

Q: Are there packaging differences between substitute parts?

A: Yes. The main part AMK063ABJ105MP-F is supplied in Tape & Reel (TR) packaging. Substitute parts are available in Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel® packaging. Both packaging formats are suitable for automated assembly; selection depends on production line equipment and volume requirements.

Q: Why is the AMK063ABJ105MP-F marked "Not For New Designs"?

A: This status indicates the part is in mature or declining production phase. Taiyo Yuden recommends using alternative parts for new circuit designs. Existing designs using this part can continue with direct equivalents or upgrades from active manufacturers.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All listed substitute parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the AMK063ABJ105MP-F.

Q: What is the significance of the X5R temperature coefficient?

A: X5R specifies the capacitance change across the operating temperature range of -55°C to 85°C. X5R rated capacitors maintain stable capacitance within ±15% across this full temperature range, making them suitable for applications requiring consistent performance across wide temperature variations.

Q: Can I substitute parts from different manufacturers?

A: Yes. All listed substitute parts from YAGEO, Samsung Electro-Mechanics, and KYOCERA AVX meet the identical electrical and mechanical specifications required for the 0201 package form factor and X5R temperature coefficient. Cross-manufacturer substitution is standard practice in MLCC applications.

Q: What is MSL 1 (Unlimited) moisture sensitivity?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. This is the least restrictive moisture sensitivity level and simplifies inventory management and assembly processes.
