Substitute Part Grouping Explanation

Substitution logic for the CL21B474KOFNNNF is based on the following allowed parameters:

Capacitance: All substitutes maintain 0.47 µF capacitance value.

Tolerance: All substitutes maintain ±10% tolerance specification.

Temperature Coefficient: All substitutes maintain X7R temperature coefficient, ensuring stable capacitance across the -55°C to 125°C operating range.

Package / Case: All substitutes use 0805 (2012 Metric) surface-mount package with identical physical dimensions (2.00mm × 1.25mm).

Mounting Type: All substitutes are surface-mount MLCCs compatible with standard PCB assembly processes.

Compliance: All substitutes are ROHS3 compliant and REACH unaffected.

Voltage Rating: Substitutes are grouped into three categories:

Parametric Equivalents (16V): Identical voltage rating; differ only in packaging format (Tape & Reel variants) or internal construction codes.
Upgrade Substitutes (25V and 50V): Higher voltage ratings provide increased design margin and reliability in applications where the original 16V rating is sufficient but higher voltage tolerance is beneficial.
Direct Alternatives (KEMET, Taiyo Yuden): Different manufacturers offering equivalent electrical specifications with identical package and performance characteristics.

Engineering Selection Recommendations

For Parametric Equivalents (16V Rating):

CL21B474KOFNNNE and CL21B474KOFNNNG are direct parametric equivalents to CL21B474KOFNNNF, differing only in internal construction codes. Both are Active status parts with significantly higher inventory availability (240200 and 238078 pieces respectively). These parts are suitable for direct substitution in applications requiring 16V rated capacitors with identical electrical performance.

For Voltage Upgrade Substitutes (25V and 50V Ratings):

The 25V-rated variants (CL21B474KAFNNNE, CL21B474KAFNNNG, CL21B474KAFNNWG) and 50V-rated variants (CL21B474KBFNFNE, CL21B474KBFNNNE, CL21B474KBFNNNG) are all Active status parts. These higher voltage ratings provide increased design margin in applications where 16V is adequate but additional voltage headroom is desired. CL21B474KAFNNNG (25V, Tape & Reel) and CL21B474KBFNNNG (50V, Cut Tape) offer the highest inventory levels (729803 and 369511 pieces respectively).

For Alternative Manufacturers:

C0805C474K4RAC7800 (KEMET) is an Active status direct alternative with identical 16V rating, X7R temperature coefficient, and 0805 package. Inventory of 29050 pieces supports immediate availability.

EMK212B7474KD-T (Taiyo Yuden) is marked as "Not For New Designs," indicating this part is in end-of-life status. While 100186 pieces are in stock, this part is not recommended for new design implementations.

Compliance and Certifications:

All recommended substitutes maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility with the original part specification.

Frequently Asked Questions (FAQ)

Q: Can I substitute CL21B474KOFNNNF with a higher voltage-rated part such as CL21B474KAFNNNG (25V)?

A: Yes. The 25V-rated CL21B474KAFNNNG is electrically compatible with applications designed for 16V operation. Higher voltage ratings provide increased safety margin and do not degrade performance in lower-voltage applications. All other parameters (capacitance, tolerance, temperature coefficient, package, and compliance) remain identical.

Q: What is the difference between the parametric equivalents CL21B474KOFNNNE and CL21B474KOFNNNG?

A: Both parts are 16V rated, 0.47 µF, X7R ceramic capacitors in 0805 package with identical electrical specifications. The difference lies in internal construction codes (the final characters of the part number). Both are Active status and suitable for direct substitution. Selection between them is based on inventory availability and packaging format preference.

Q: Are there packaging format differences between the substitute parts?

A: Yes. The original CL21B474KOFNNNF is supplied in Tape & Reel (TR) format. Some substitutes are available in Cut Tape (CT) & Digi-Reel® format. Both packaging formats are compatible with standard surface-mount assembly equipment. Selection depends on production volume and assembly line requirements.

Q: Why is EMK212B7474KD-T marked as "Not For New Designs"?

A: This Taiyo Yuden part is in end-of-life status. While inventory is currently available, the manufacturer has discontinued active support for new designs. For long-term supply chain stability, Active status parts such as Samsung CL series or KEMET C0805C series are recommended.

Q: Can I use KEMET C0805C474K4RAC7800 as a direct replacement?

A: Yes. The KEMET part is a direct alternative with identical 0.47 µF capacitance, 16V rating, X7R temperature coefficient, and 0805 package. It is Active status with 29050 pieces in inventory. Electrical performance and physical compatibility are equivalent to the Samsung part.

Q: What parameters must remain constant for a part to be considered a valid substitute?

A: The following parameters must remain identical: capacitance (0.47 µF), tolerance (±10%), temperature coefficient (X7R), package type (0805 / 2012 Metric), mounting type (surface mount MLCC), operating temperature range (-55°C to 125°C), and compliance certifications (ROHS3, REACH unaffected). Voltage rating may be equal or higher. Packaging format (Tape & Reel vs. Cut Tape) and manufacturer may differ.
