CL05B103KB5NNND Equivalent & Substitute Parts

Part Overview

The CL05B103KB5NNND is a 10000 pF ±10% 50V ceramic capacitor manufactured by Samsung Electro-Mechanics in the 0402 (1005 Metric) package with X7R temperature coefficient. This surface mount multilayer ceramic capacitor (MLCC) is designed for general purpose applications and operates across the temperature range of -55°C to 125°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Substitute parts are necessary when the original part becomes unavailable, when alternative packaging formats are required for manufacturing efficiency, or when upgraded versions with enhanced ratings (such as AEC-Q200 automotive qualification) are specified for design improvements.

Engineering Selection Recommendations

For General Purpose Applications (Non-Automotive):

The parametric equivalents CL05B103KB5NFNC and CL05B103KB5NNNC from Samsung Electro-Mechanics provide direct functional replacement with identical electrical specifications. Both are Active products with ROHS3 compliance. Selection between these and the original CL05B103KB5NNND should be based on packaging format availability: Tape & Reel for CL05B103KB5NFNC or Cut Tape & Digi-Reel for CL05B103KB5NNNC.

The Murata Electronics alternatives GRM155R71H103KA88D and GRM155R71H103KA88J are Active products meeting all electrical and mechanical requirements. Both offer high inventory availability and are suitable for direct substitution in general purpose circuits.

For Automotive and High-Reliability Applications:

The upgrade versions CL05B103KB5VPJC and CL05B103KB5VPNC from Samsung Electro-Mechanics include AEC-Q200 automotive qualification. These are recommended when design specifications require automotive-grade components. CL05B103KB5VPNC offers significantly higher inventory (1,243,647 units) compared to CL05B103KB5VPJC (3,638 units).

The YAGEO alternatives AC0402KPX7R9BB103 and AC0402KRX7R9BB103 are both Active products with AEC-Q200 ratings. AC0402KPX7R9BB103 is available in Tape & Reel packaging with 275,508 units in stock, while AC0402KRX7R9BB103 is available in Cut Tape & Digi-Reel format with 3,300 units.

Parts Not Recommended for New Designs:

TDCF500W103K1GV001T (Johanson Dielectrics) is marked Obsolete and should not be selected for new designs despite meeting electrical specifications.

UMK105B7103KV-F (Taiyo Yuden) is marked Not For New Designs and should be avoided in new product development.

Frequently Asked Questions (FAQ)

Q: Can I substitute CL05B103KB5NNND with any of the listed alternatives without circuit redesign?

A: Yes. All listed alternatives meet the identical electrical specifications: 10000 pF ±10% capacitance, 50V voltage rating, X7R temperature coefficient, and -55°C to 125°C operating range. The 0402 package dimensions are standardized across all alternatives. No circuit redesign is required for direct substitution.

Q: What is the difference between the Samsung upgrade versions CL05B103KB5VPJC and CL05B103KB5VPNC?

A: Both are identical in electrical and mechanical specifications. The primary difference is packaging format: CL05B103KB5VPJC uses Cut Tape & Digi-Reel packaging, while CL05B103KB5VPNC uses the same format but with significantly higher inventory availability (1,243,647 units versus 3,638 units). Both include AEC-Q200 automotive qualification and Soft Termination features.

Q: Should I use AEC-Q200 rated parts for non-automotive applications?

A: AEC-Q200 rated parts (CL05B103KB5VPJC, CL05B103KB5VPNC, AC0402KPX7R9BB103, AC0402KRX7R9BB103) are qualified for automotive use but are fully compatible with general purpose applications. Selection should be based on design requirements and cost considerations rather than application type alone.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging?

A: Both are surface mount packaging formats suitable for automated assembly. Tape & Reel is continuous reel packaging for high-volume production. Cut Tape & Digi-Reel provides flexibility for lower volumes or mixed component orders. The electrical and mechanical specifications of the component remain identical regardless of packaging format.

Q: Why is TDCF500W103K1GV001T marked as Obsolete?

A: Johanson Dielectrics has discontinued this part number. Although it meets all electrical specifications, it should not be selected for new designs due to potential supply discontinuation and lack of long-term availability assurance.

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

A: Yes. All listed alternatives meet identical electrical and mechanical specifications and are ROHS3 compliant with MSL 1 rating. Manufacturing process differences between Samsung, Murata, and YAGEO do not affect functional compatibility in this application category. Mixing manufacturers is acceptable from an engineering standpoint, though procurement and quality assurance procedures should be followed.

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

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. This applies to all listed alternatives, eliminating moisture-related supply chain constraints.
