Key Parameters

Substitute Part Grouping Explanation

Substitution of the 0603F474M100CT is determined by the following critical parameters:

• Capacitance Value: 0.47 µF (exact match required)
• Voltage Rating: 10V (minimum requirement; higher ratings acceptable)
• Package / Case: 0603 (1608 Metric) (physical and electrical compatibility)
• Mounting Type: Surface Mount, MLCC (assembly process compatibility)
• Tolerance: ±20% (electrical performance specification)

The substitute part 0603X474M100CT meets all mandatory substitution criteria. The primary difference is the temperature coefficient classification (X5R versus Y5V), which affects capacitance stability across temperature ranges but maintains functional equivalence for general-purpose applications. Both parts share identical capacitance, voltage rating, package dimensions, and tolerance specifications.

Parameter Comparison

Engineering Selection Recommendations

The 0603X474M100CT is the direct substitute for the obsolete 0603F474M100CT. Selection is based on the following factors:

• Product Status: The substitute part maintains active product status, ensuring continued availability and manufacturing support.
• Compliance: Both parts are ROHS3 compliant and REACH unaffected, meeting regulatory requirements.
• Electrical Equivalence: Identical capacitance, tolerance, and voltage rating specifications ensure functional compatibility in circuit applications.
• Temperature Performance: The X5R temperature coefficient provides extended lower temperature operation (-55°C versus -25°C), offering broader environmental capability than the original Y5V specification.
• Physical Compatibility: Identical package dimensions and mounting type ensure direct PCB layout compatibility without redesign.
• Thickness Variance: The substitute part thickness increases by 0.003" (0.08mm), which remains within typical PCB assembly tolerances for 0603 components.

Frequently Asked Questions (FAQ)

Q: Can the 0603X474M100CT directly replace the 0603F474M100CT without circuit modification?

A: Yes. Both parts share identical capacitance (0.47 µF), tolerance (±20%), voltage rating (10V), and package dimensions (0603). Direct substitution is electrically and mechanically compatible.

Q: What is the difference between Y5V and X5R temperature coefficients?

A: Y5V and X5R are temperature coefficient classifications that define capacitance stability across operating temperature ranges. Y5V operates from -25°C to 85°C with specified capacitance variation. X5R operates from -55°C to 85°C with tighter capacitance tolerance across temperature. For applications within the -25°C to 85°C range, both coefficients provide equivalent performance.

Q: Is the thickness difference between the two parts significant?

A: The substitute part is 0.003" (0.08mm) thicker. This variance is within standard PCB assembly tolerances for 0603 surface mount components and does not affect board-level compatibility or assembly processes.

Q: Why is the original part obsolete?

A: Product obsolescence is determined by manufacturer discontinuation. The active substitute part 0603X474M100CT provides equivalent functionality with extended environmental operating range.

Q: Are both parts RoHS compliant?

A: Yes. Both the 0603F474M100CT and 0603X474M100CT are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What packaging options are available for the substitute part?

A: The 0603X474M100CT is available in Tape & Reel (TR) packaging, standard for high-volume surface mount assembly operations.
