CL05C680JB5NFNC Ceramic Capacitor 68pF 50V C0G/NP0 0402 Equivalent & Substitute Parts

Part Overview

The CL05C680JB5NFNC is a surface-mount multilayer ceramic capacitor (MLCC) manufactured by Samsung Electro-Mechanics. This 68 pF, 50V rated capacitor features C0G/NP0 temperature coefficient characteristics and is packaged in the 0402 (1005 Metric) form factor. The part is classified as Active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Substitute parts are necessary when the original manufacturer part becomes unavailable, when alternative packaging formats are required (such as Tape & Reel instead of cut tape), or when design requirements mandate specific certifications such as AEC-Q200 for automotive applications. This reference provides direct equivalents and parametric alternatives that maintain electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitute parts for the CL05C680JB5NFNC are categorized based on the following substitution criteria:

Parametric Equivalents: Parts that maintain identical electrical specifications (68 pF, ±5%, 50V, C0G/NP0) and mechanical compatibility (0402 package, surface mount) but differ in packaging format or manufacturer. These parts are directly interchangeable in circuit design and PCB layout.

Upgrade Variants: Parts that exceed the original specifications in specific areas while maintaining core electrical parameters. Upgrades include:

Enhanced tolerance (±1% or ±2% versus ±5%)
Extended temperature range (-55°C to 150°C versus -55°C to 125°C)
Automotive-grade certification (AEC-Q200)
Low ESL (Equivalent Series Inductance) features

Direct Manufacturer Alternatives: Parts from competing manufacturers (TDK, Murata, Taiyo Yuden, YAGEO, KEMET) that provide identical electrical and mechanical specifications. These maintain full circuit compatibility while offering supply chain flexibility.

Key Substitution Parameters:

Capacitance value: 68 pF (fixed)
Voltage rating: 50V minimum (higher ratings acceptable)
Temperature coefficient: C0G/NP0 (mandatory for stability)
Package: 0402 (1005 Metric) (fixed for PCB compatibility)
Tolerance: ±5% or tighter (tighter tolerance acceptable)

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): Select CL05C680JB5NNNC when Tape & Reel packaging is required instead of cut tape. Both parts are Samsung Electro-Mechanics products with Active status and identical electrical parameters.

For Automotive Applications: Parts with AEC-Q200 certification are required for automotive-grade designs:

CL05C680JB51PNC (Samsung, Automotive-grade)
AC0402JRNPO9BN680 (YAGEO, Automotive-grade)
AQ0402JRNPO9BN680 (YAGEO, Automotive-grade)
C0402C680J5GACAUTO (KEMET, Automotive-grade)

For Extended Temperature Range: C1005NP01H680J050BA (TDK) provides -55°C to 150°C operating range, exceeding the standard -55°C to 125°C specification.

For Tighter Tolerance Requirements:

C0402C680F5GAC7867 (KEMET, ±1% tolerance)
C0402C680G5GAC7867 (KEMET, ±2% tolerance)

Frequently Asked Questions (FAQ)

Q: Can I substitute CL05C680JB5NFNC with CL05C680JB5NNNC? A: Yes. Both parts are identical in electrical specifications (68 pF, ±5%, 50V, C0G/NP0, 0402 package). The difference is packaging format: CL05C680JB5NFNC is cut tape while CL05C680JB5NNNC is Tape & Reel. Select based on your assembly process requirements.

Q: What is the difference between C0G and NP0 temperature coefficients? A: C0G and NP0 designations are equivalent specifications from different standards organizations. Both indicate zero temperature coefficient with ±30 ppm/°C stability across the operating temperature range. They are interchangeable.

Q: Can I use a part with ±1% tolerance instead of ±5%? A: Yes. Tighter tolerance (±1% or ±2%) is a specification upgrade that maintains full compatibility. The capacitor will perform within the original ±5% requirement while providing superior accuracy. KEMET C0402C680F5GAC7867 (±1%) and C0402C680G5GAC7867 (±2%) are direct upgrades.

Q: Are KEMET parts with "Low ESL" features compatible? A: Yes. Low ESL (Equivalent Series Inductance) is an additional performance feature that does not affect basic electrical compatibility. KEMET C0402C680F5GAC7867, C0402C680G5GAC7867, and C0402C680J5GACAUTO maintain the same 68 pF, 50V, C0G/NP0 specifications with enhanced inductance characteristics.

Q: Which parts are suitable for automotive applications? A: Parts with AEC-Q200 certification are required for automotive designs: CL05C680JB51PNC (Samsung), AC0402JRNPO9BN680 (YAGEO), AQ0402JRNPO9BN680 (YAGEO), and C0402C680J5GACAUTO (KEMET). These meet automotive reliability and qualification standards.

Q: What does "Not For New Designs" mean? A: This status indicates the manufacturer is discontinuing the product line. GRM1555C1H680JA01D (Murata) and UMK105CG680JV-F (Taiyo Yuden) should only be used for repair or maintenance of existing systems. For new product development, select from Active status parts.

Q: Can I use a 100V rated capacitor instead of 50V? A: While higher voltage ratings provide additional safety margin, this information is not provided in the substitute parts list. Substitution must be based only on the parameters explicitly provided. Verify voltage rating specifications before substitution.

Q: Does MSL 1 (Unlimited) affect storage or handling? A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All listed substitute parts maintain MSL 1 rating, ensuring identical storage and handling requirements.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All parts listed in this reference maintain ROHS3 compliance, ensuring compatibility with environmental regulations and customer requirements.
