CL21B225KOFNNNF Equivalent & Substitute Parts

Part Overview

The CL21B225KOFNNNF is a 2.2 µF ±10% 16V ceramic capacitor manufactured by Samsung Electro-Mechanics in the CL series. This surface mount multilayer ceramic capacitor (MLCC) features X7R temperature coefficient characteristics and is packaged in 0805 (2012 Metric) form factor. The part is classified as Active product status and is ROHS3 compliant with MSL 1 rating, indicating unlimited moisture sensitivity protection.

Equivalent and substitute parts are necessary when the original part number becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design specifications allow for higher voltage ratings to improve circuit reliability margins.

Substitute Part Grouping Explanation

Substitute parts for the CL21B225KOFNNNF are organized into three categories based on substitution criteria:

Upgrade Substitutes (Higher Voltage Rating): Parts with identical capacitance (2.2 µF), tolerance (±10%), temperature coefficient (X7R), package (0805), and operating temperature range (-55°C ~ 125°C), but with increased voltage rating (25V instead of 16V). These parts provide enhanced voltage margin and are direct functional upgrades. Voltage rating is the primary differentiating parameter; all other electrical and mechanical specifications remain compatible.

Parametric Equivalents (Same Voltage, Different Packaging): Parts with identical electrical specifications (2.2 µF, ±10%, 16V, X7R, -55°C ~ 125°C) and package footprint (0805), but with different tape and reel configurations (Cut Tape vs. Tape & Reel). These parts differ only in manufacturing packaging format, not in component performance or PCB compatibility.

Direct Equivalents (Alternative Manufacturers): Parts from KEMET and TDK Corporation with matching capacitance (2.2 µF), tolerance (±10%), voltage (16V), temperature coefficient (X7R), package (0805), and operating temperature range (-55°C ~ 125°C). These represent cross-manufacturer alternatives with identical electrical and mechanical performance.

Engineering Selection Recommendations

For Active Product Status Designs:

Use CL21B225KOFVPNE, CL21B225KOFNFNE, or CL21B225KOFNNNE when Samsung Electro-Mechanics parts are specified and the original part becomes unavailable. All three maintain identical electrical specifications and 0805 package compatibility. CL21B225KOFVPNE includes AEC-Q200 automotive qualification if automotive-grade reliability is required.

Use C0805C225K4RAC7800 (KEMET) or C2012X7R1C225K125AB (TDK) as cross-manufacturer alternatives when multi-source qualification is required. Both parts maintain identical capacitance, voltage, tolerance, temperature coefficient, and package specifications.

For Voltage Margin Enhancement:

Use CL21B225KAFNNNG or CL21B225KAFNNWE when circuit design allows for higher voltage rating. Both parts provide 25V rating with identical capacitance, tolerance, temperature coefficient, and package footprint. CL21B225KAFNNWE has significantly higher inventory availability (765,877 pcs).

For Packaging Format Flexibility:

Use CL21B225KOFNFNE or CL21B225KOFNNNE when Cut Tape or alternative reel configurations are required for specific manufacturing processes. Both maintain identical electrical specifications to the original part.

Parts to Avoid for New Designs:

CL21B225KAFNNNE and C2012X7R1C225K085AB are marked "Not For New Designs" and should not be selected for new product development.

Frequently Asked Questions (FAQ)

Q: Can CL21B225KAFNNNG (25V) be used as a direct replacement for CL21B225KOFNNNF (16V)?

A: Yes. The 25V part is a functional upgrade with identical capacitance (2.2 µF), tolerance (±10%), temperature coefficient (X7R), package (0805), and operating temperature range (-55°C ~ 125°C). Higher voltage rating provides additional safety margin and does not affect circuit performance in applications designed for 16V or lower.

Q: What is the difference between CL21B225KOFNNNF and CL21B225KOFNFNE?

A: Both parts have identical electrical specifications (2.2 µF, 16V, ±10%, X7R, 0805). The difference is packaging format: CL21B225KOFNNNF is supplied in Tape & Reel (TR), while CL21B225KOFNFNE is supplied in Cut Tape (CT) & Digi-Reel®. Component performance is identical; packaging format affects only manufacturing process compatibility.

Q: Are KEMET and TDK alternatives fully compatible with Samsung Electro-Mechanics parts?

A: Yes, for the specified parameters. C0805C225K4RAC7800 (KEMET) and C2012X7R1C225K125AB (TDK) match all critical electrical parameters: 2.2 µF capacitance, ±10% tolerance, 16V rating, X7R temperature coefficient, 0805 package, and -55°C ~ 125°C operating temperature. All three manufacturers' parts are ROHS3 compliant with MSL 1 rating. Physical dimensions and mounting characteristics are equivalent for PCB assembly.

Q: Why is CL21B225KAFNNNE marked "Not For New Designs"?

A: Parts marked "Not For New Designs" indicate that the manufacturer has discontinued active development and support for that specific part number. While existing inventory may be available, new product designs should select alternative part numbers with "Active" status to ensure long-term supply chain stability and manufacturer support.

Q: Can I mix different manufacturers' parts in the same production batch?

A: Yes, provided all parts meet the specified electrical and mechanical parameters. All listed alternatives (Samsung, KEMET, TDK) are ROHS3 compliant, have identical 0805 package footprints, and meet the same electrical specifications. However, verify that your quality assurance procedures and supply chain documentation support multi-source component usage.

Q: What does MSL 1 (Unlimited) mean for handling?

A: MSL 1 rating indicates that the component has unlimited shelf life and does not require special moisture-controlled storage or baking procedures before assembly. This simplifies inventory management and reduces handling complexity compared to higher MSL ratings.

Q: Are there any thickness differences between substitute parts?

A: Yes. The original CL21B225KOFNNNF has maximum thickness of 0.053" (1.35mm). KEMET C0805C225K4RAC7800 has 0.055" (1.40mm), and TDK C2012X7R1C225K085AB has 0.039" (1.00mm). These minor variations are within standard 0805 package tolerances and do not affect PCB assembly compatibility. Verify clearance in your specific PCB design if height-constrained applications are involved.
