Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMK063BJ334MP-F is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 0.33 µF
• Tolerance: ±20%
• Temperature Coefficient: X5R
• Package / Case: 0201 (0603 Metric)
• Mounting Type: Surface Mount, MLCC
• Operating Temperature Range: -55°C ~ 85°C
• Physical Dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm)
• Thickness (Max): 0.015" (0.39mm)

Allowable Variation Parameters:

• Voltage - Rated: May be equal to or greater than the original 4V rating, provided the circuit design accommodates the higher voltage specification

The substitute part JMK063BJ334MP-F meets all mandatory matching parameters. The voltage rating difference (6.3V versus 4V) represents an upward specification that is electrically compatible in applications designed for the original 4V component.

Parameter Comparison

Engineering Selection Recommendations

The JMK063BJ334MP-F serves as a direct functional substitute for the obsolete AMK063BJ334MP-F. Both components are manufactured by Taiyo Yuden and share identical electrical specifications for capacitance, tolerance, temperature coefficient, and operating temperature range. The physical footprint and mounting characteristics are identical, enabling direct board-level replacement without layout modifications.

The voltage rating increase from 4V to 6.3V in the substitute part represents an upward specification margin. This characteristic is compatible with the original application provided the circuit design does not depend on the lower voltage rating for specific functional behavior.

Both parts maintain ROHS3 compliance and MSL 1 classification, ensuring compatibility with standard manufacturing and storage protocols. The substitute part is available in Tape & Reel packaging, suitable for automated assembly processes.

The substitute part carries a "Not For New Designs" status, indicating it is suitable for replacement and maintenance applications but not recommended for new product development initiatives.

Frequently Asked Questions (FAQ)

Q: Can JMK063BJ334MP-F replace AMK063BJ334MP-F in existing designs?

A: Yes. The JMK063BJ334MP-F is electrically and mechanically compatible. Both parts share identical capacitance (0.33 µF), tolerance (±20%), temperature coefficient (X5R), package (0201), and operating temperature range (-55°C ~ 85°C). The higher voltage rating (6.3V versus 4V) does not prevent substitution in applications originally designed for 4V operation.

Q: What is the significance of the voltage rating difference?

A: The substitute part has a 6.3V rating compared to the original 4V rating. This represents a higher voltage specification margin and is electrically compatible with circuits designed for the lower voltage. The capacitor will function correctly in the original application.

Q: Are the physical dimensions identical?

A: Yes. Both parts are specified as 0201 (0603 Metric) with dimensions of 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum thickness of 0.015" (0.39mm). Direct board-level substitution is possible without layout changes.

Q: What is the difference in product status between the two parts?

A: The main part (AMK063BJ334MP-F) is classified as Obsolete, indicating it is no longer in production. The substitute part (JMK063BJ334MP-F) is classified as "Not For New Designs," meaning it is available for replacement and maintenance but not recommended for new product development.

Q: Are both parts RoHS compliant?

A: Yes. Both AMK063BJ334MP-F and JMK063BJ334MP-F are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity classification.

Q: What packaging options are available?

A: The substitute part JMK063BJ334MP-F is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. The original part packaging specification was not provided.
