Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CL21F475ZOFNNNE is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 4.7 µF (exact match required)
• Voltage Rating: 16V (minimum requirement; higher ratings acceptable)
• Package / Case: 0805 (2012 Metric) (physical and electrical compatibility)
• Mounting Type: Surface Mount, MLCC (assembly process compatibility)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

Flexible Parameters (Substitution Allowed):

• Temperature Coefficient: Y5V or X5R acceptable (both meet general purpose applications)
• Tolerance: -20%/+80% (Y5V) or ±10% (X5R) acceptable based on circuit requirements
• Operating Temperature Range: -30°C ~ 85°C (Y5V) or -55°C ~ 85°C (X5R) acceptable
• Product Status: Active preferred over obsolete for long-term availability
• Packaging Format: Cut Tape (CT), Digi-Reel®, or Tape & Reel (TR) acceptable

Two substitute parts meet these criteria with different temperature coefficient classifications, enabling selection based on specific application thermal requirements.

Parameter Comparison

Engineering Selection Recommendations

CL21A475KOFNNNE Selection Criteria: This Samsung Electro-Mechanics substitute maintains manufacturer continuity and is classified as active product status, ensuring long-term availability. The X5R temperature coefficient provides an extended operating temperature range (-55°C ~ 85°C) compared to the Y5V main part (-30°C ~ 85°C), offering superior thermal stability. The ±10% tolerance is tighter than the main part's -20%/+80% specification, providing improved capacitance accuracy. Physical dimensions remain identical to the main part (0.079" L x 0.049" W, 0.053" max thickness), ensuring direct PCB compatibility. ROHS3 compliance and MSL 1 rating match the main part specifications.

KGM21AV51C475ZU Selection Criteria: This KYOCERA AVX substitute provides direct functional equivalence with identical Y5V temperature coefficient and -20%/+80% tolerance matching the main part. Active product status ensures procurement continuity. The part maintains 0805 package form factor with minimal dimensional variance (0.079" L x 0.049" W, 0.057" max thickness versus 0.053" for the main part). This 0.004" thickness difference requires verification against PCB assembly height constraints in space-limited applications. ROHS3 compliance and MSL 1 rating are maintained. Tape & Reel packaging format supports high-volume production environments.

Selection Logic:

• For applications requiring exact thermal coefficient matching and tighter tolerance: CL21A475KOFNNNE (X5R, ±10%)
• For applications requiring identical electrical characteristics with alternative manufacturer: KGM21AV51C475ZU (Y5V, -20%/+80%)
• For space-constrained PCB designs: CL21A475KOFNNNE (0.053" max thickness)
• For high-volume production: KGM21AV51C475ZU (Tape & Reel packaging)

Frequently Asked Questions (FAQ)

Q: Can CL21A475KOFNNNE replace CL21F475ZOFNNNE in all applications?

A: CL21A475KOFNNNE is functionally compatible for general purpose applications. The X5R temperature coefficient provides superior thermal stability across -55°C ~ 85°C versus Y5V's -30°C ~ 85°C. The ±10% tolerance is tighter than Y5V's -20%/+80%. Verify circuit requirements for temperature coefficient sensitivity before substitution.

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

A: Y5V dielectric exhibits -20% to +80% capacitance change across the operating temperature range with lower cost and higher volumetric efficiency. X5R dielectric exhibits ±15% capacitance change across -55°C ~ 85°C with superior stability. X5R is preferred for precision applications; Y5V is acceptable for general purpose filtering and coupling.

Q: Are the physical dimensions identical between all three parts?

A: CL21F475ZOFNNNE and CL21A475KOFNNNE share identical dimensions (0.079" L x 0.049" W, 0.053" max thickness). KGM21AV51C475ZU has slightly greater thickness (0.057" max) due to manufacturer design. Verify PCB assembly height constraints before selecting KGM21AV51C475ZU in space-limited designs.

Q: What packaging formats are available for each substitute?

A: CL21F475ZOFNNNE is supplied in Cut Tape (CT). CL21A475KOFNNNE is available in Cut Tape (CT) and Digi-Reel® formats. KGM21AV51C475ZU is supplied in Tape & Reel (TR) format. Select packaging based on production volume and assembly equipment compatibility.

Q: Are all parts RoHS3 compliant?

A: Yes. CL21F475ZOFNNNE, CL21A475KOFNNNE, and KGM21AV51C475ZU are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting regulatory requirements for commercial and industrial applications.

Q: Why is CL21F475ZOFNNNE classified as obsolete?

A: Obsolete status indicates Samsung Electro-Mechanics has discontinued this product line. CL21A475KOFNNNE (active status) is the recommended Samsung replacement. KGM21AV51C475ZU provides equivalent functionality from an alternative qualified manufacturer.

Q: Can inventory of CL21F475ZOFNNNE be used interchangeably with substitutes?

A: Yes, for general purpose applications. Existing inventory (1083 Pcs) can be used until depletion. Transition to active substitutes (CL21A475KOFNNNE: 2330 Pcs or KGM21AV51C475ZU: 4801 Pcs) for new production to ensure long-term supply continuity.
