LMK063C6473MP-F Equivalent & Substitute Parts

Part Overview

The LMK063C6473MP-F is a 0.047 µF ceramic capacitor manufactured by Taiyo Yuden, rated for 10V operation with X6S temperature coefficient characteristics. This component is designed for surface mount applications in SMPS filtering circuits, packaged in the 0201 (0603 Metric) form factor. The part carries a "Not For New Designs" product status, indicating that alternative components should be evaluated for new circuit implementations. Identifying equivalent and substitute parts is necessary to support ongoing maintenance, repair, and legacy system requirements where this capacitor specification remains in use.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LMK063C6473MP-F is determined by strict adherence to the following electrical and mechanical parameters:

Critical Substitution Parameters:

• Capacitance value must remain 0.047 µF
• Voltage rating must be equal to or greater than 10V
• Temperature coefficient must be X6S
• Tolerance must be ±20%
• Operating temperature range must encompass -55°C ~ 105°C
• Package / Case must be 0201 (0603 Metric)
• Mounting type must be Surface Mount, MLCC
• Physical dimensions must match: 0.024" L x 0.012" W (0.60mm x 0.30mm)
• Thickness must not exceed 0.013" (0.33mm)
• RoHS3 compliance is required
• MSL rating must be 1 (Unlimited)

The substitute part LMK063C6104MP-F does not meet the critical substitution criteria for the LMK063C6473MP-F. While both components share identical package specifications, voltage rating, temperature coefficient, tolerance, operating temperature range, RoHS compliance, and MSL rating, the capacitance value differs: LMK063C6104MP-F is rated at 0.1 µF, which is 2.13 times greater than the required 0.047 µF specification. This capacitance difference renders it unsuitable as a direct substitute in circuits designed for the 0.047 µF value.

Parameter Comparison

Engineering Selection Recommendations

Based on the provided technical specifications and compliance data, the LMK063C6104MP-F cannot be used as a direct substitute for the LMK063C6473MP-F due to the capacitance value mismatch (0.1 µF versus 0.047 µF). Both components share identical mechanical packaging, voltage ratings, temperature coefficients, and regulatory compliance status (ROHS3 Compliant, MSL 1). However, the significant difference in capacitance value means the LMK063C6104MP-F will not perform the intended filtering function in circuits designed for 0.047 µF operation.

For applications requiring the LMK063C6473MP-F specification, direct equivalent parts with matching 0.047 µF capacitance, 10V rating, X6S temperature coefficient, and 0201 package must be sourced. The "Not For New Designs" status of both components indicates that new circuit designs should evaluate current-generation alternatives from Taiyo Yuden or other manufacturers offering equivalent specifications in active product lines.

Frequently Asked Questions (FAQ)

Q: Can LMK063C6104MP-F replace LMK063C6473MP-F in my circuit?

A: No. While both components share identical package dimensions, voltage ratings, and temperature characteristics, the capacitance values differ significantly (0.1 µF versus 0.047 µF). Direct substitution will alter circuit performance and is not acceptable.

Q: What makes two ceramic capacitors equivalent?

A: Equivalent ceramic capacitors must match on all critical parameters: capacitance value, tolerance, voltage rating, temperature coefficient, operating temperature range, package type, physical dimensions, and compliance certifications. A difference in any single parameter disqualifies substitution.

Q: Are both parts physically compatible with the same PCB footprint?

A: Yes. Both LMK063C6473MP-F and LMK063C6104MP-F use the 0201 (0603 Metric) package with identical dimensions (0.024" L x 0.012" W, 0.60mm x 0.30mm) and maximum thickness (0.013" / 0.33mm). Physical compatibility does not ensure functional equivalence.

Q: What does "Not For New Designs" mean?

A: This product status indicates that the component is in mature or end-of-life phase and should not be selected for new circuit development. Existing systems using these parts may continue to source them for maintenance and repair, but new designs should evaluate current-generation alternatives.

Q: Are both parts RoHS compliant?

A: Yes. Both LMK063C6473MP-F and LMK063C6104MP-F are ROHS3 Compliant with MSL rating of 1 (Unlimited), meeting current environmental and regulatory requirements.

Q: What is the significance of the X6S temperature coefficient?

A: X6S indicates a temperature coefficient range of ±15% over the operating temperature range of -55°C to +105°C. This specification ensures stable capacitance performance across the full operating environment and is a critical parameter for filtering applications in SMPS circuits.
