CL05C221JB5NFNC Equivalent & Substitute Parts

Part Overview

The CL05C221JB5NFNC is a 220 pF ±5% 50V ceramic capacitor manufactured by Samsung Electro-Mechanics in the 0402 (1005 Metric) package with C0G/NP0 temperature coefficient. This component is classified as Active product status and is suitable for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C.

Substitute parts are necessary when the primary part experiences supply constraints, inventory limitations, or when design requirements mandate specific certifications such as AEC-Q200 automotive qualification or alternative packaging formats (Tape & Reel versus Cut Tape).

Frequently Asked Questions (FAQ)

Q: Can I substitute CL05C221JB5NFNC with GRM1555C1H221JA01J?

A: Yes. Both parts share identical electrical specifications: 220 pF capacitance, ±5% tolerance, 50V voltage rating, C0G/NP0 temperature coefficient, and 0402 package. The primary difference is packaging format (Cut Tape vs. Tape & Reel) and manufacturer. GRM1555C1H221JA01J is Active status with higher inventory availability.

Q: What is the difference between C0G and NP0 temperature coefficients?

A: C0G and NP0 designations are equivalent. Both indicate zero temperature coefficient, meaning capacitance remains stable across the operating temperature range. The terminology varies by manufacturer but represents identical performance.

Q: Is the ±1% tolerance part C0402C221F5GAC7867 compatible with designs specified for ±5%?

A: Yes. Tighter tolerance (±1%) is compatible with ±5% specifications. The ±1% part will perform within the ±5% requirement while providing superior tolerance performance. This is an upgrade substitution.

Q: Can I use parts rated for higher voltage than 50V?

A: Yes. A 100V-rated capacitor can substitute for a 50V-rated capacitor in the same package. Higher voltage rating provides additional safety margin. However, verify that the physical dimensions remain identical (0402 package).

Q: What does AEC-Q200 certification mean?

A: AEC-Q200 is an automotive qualification standard indicating the component meets reliability and performance requirements for automotive applications. Parts with AEC-Q200 (CL05C221JB51PNC, AC0402JRNPO9BN221, AC0402JPNPO9BN221) are suitable for automotive designs. General-purpose parts without this certification are not recommended for automotive applications.

Q: Why do some parts show "Not For New Designs" status?

A: "Not For New Designs" indicates the manufacturer is phasing out the product. UMK105CG221JV-F should only be used for maintaining existing designs. For new designs, select Active status parts such as GRM1555C1H221JA01J or CL05C221JB51PNC.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL (Moisture Sensitivity Level) 1 indicates the component has unlimited shelf life and requires no special moisture-control handling. All listed substitutes share this rating, eliminating moisture-related storage and assembly concerns.

Q: Can I mix packaging formats (Cut Tape vs. Tape & Reel) in the same design?

A: Yes. Cut Tape (CT) and Tape & Reel (TR) formats contain identical components. The difference is procurement and handling format. Select based on your assembly equipment and procurement volume requirements. Digi-Reel® is an alternative reel format compatible with standard tape-and-reel equipment.

Q: Which substitute offers the best value for high-volume production?

A: GRM1555C1H221JA01J (Murata Electronics) offers the highest inventory (636146 Pcs) and Active status, making it suitable for high-volume procurement. For automotive applications, CL05C221JB51PNC provides AEC-Q200 qualification with substantial inventory (121762 Pcs).

Q: Are all listed substitutes RoHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 Compliant, meeting regulatory requirements for lead-free and restricted substance compliance.
