Substitute Part Grouping Explanation

Substitute parts are organized into three categories based on electrical and mechanical compatibility with the main part CL21B103KBANNWC:

Direct Equivalents (Same Electrical Specifications): Parts with identical capacitance (10000 pF), tolerance (±10%), voltage rating (50V), and temperature coefficient (X7R). These differ only in packaging format (Cut Tape vs. Tape & Reel) or minor manufacturing variations. Direct equivalents include Samsung CL21B103KBCNNNC, CL21B103KBANFNC, CL21B103KBANNNC, and KEMET C0805C103K5RAC7025, C0805C103K5RAC7210, C0805C103K5RAC7800, and YAGEO CC0805KRX7R9BB103.

Voltage Upgrades (Higher Rated Voltage): Parts with identical capacitance (10000 pF), tolerance (±10%), and temperature coefficient (X7R) but with higher voltage ratings (100V, 200V, 250V). These are Samsung CL21B103KCANNNC (100V), CL21B103KDCNNNC (200V), and TDK C2012X7R2E103K125AA (250V). Voltage upgrades are electrically compatible for applications requiring the base 50V specification and provide additional design margin.

Substitution Criteria: All substitute parts maintain the 0805 (2012 Metric) package footprint, X7R temperature coefficient, -55°C to 125°C operating temperature range, ROHS3 compliance, and MSL 1 rating. Substitution is valid when the application circuit voltage requirement does not exceed the rated voltage of the substitute part.

Engineering Selection Recommendations

For Direct Substitution (50V Rating): Select from Samsung CL21B103KBCNNNC, CL21B103KBANFNC, CL21B103KBANNNC, KEMET C0805C103K5RAC7025, C0805C103K5RAC7210, C0805C103K5RAC7800, or YAGEO CC0805KRX7R9BB103. All maintain identical electrical specifications and are ROHS3 compliant with MSL 1 rating. Selection between these parts is determined by packaging format availability (Tape & Reel vs. Cut Tape) and inventory requirements. Samsung CL21B103KBANNNC offers the highest inventory (240200 Pcs) for high-volume applications.

For Voltage-Upgraded Applications: Samsung CL21B103KCANNNC (100V), CL21B103KDCNNNC (200V), or TDK C2012X7R2E103K125AA (250V) are suitable when circuit design permits higher voltage ratings. These upgrades provide additional safety margin and are electrically compatible with 50V-rated applications. Samsung CL21B103KCANNNC provides the largest inventory (876100 Pcs) among voltage upgrades.

Compliance Verification: All listed substitute parts maintain ROHS3 compliance, REACH Unaffected status, and EAR99 ECCN classification. All parts are classified as Active product status with -55°C to 125°C operating temperature range and MSL 1 moisture sensitivity level.

Thickness Consideration: The main part CL21B103KBANNWC specifies 0.030" maximum thickness. Direct equivalents from Samsung (CL21B103KBANFNC, CL21B103KBANNNC) and YAGEO (CC0805KRX7R9BB103) maintain this specification. KEMET parts specify 0.035" thickness, and voltage-upgraded parts may specify 0.037" or 0.057" thickness. Verify PCB assembly clearance requirements before selecting parts with increased thickness.

Frequently Asked Questions (FAQ)

Q: Can CL21B103KBANNWC be replaced with CL21B103KBCNNNC?

A: Yes. Both parts are identical in electrical specifications (10000 pF, ±10%, 50V, X7R). The difference is packaging format: CL21B103KBCNNNC is supplied in Cut Tape (CT) & Digi-Reel® format while the original part uses a different packaging designation. Both are ROHS3 compliant with MSL 1 rating and 0805 package footprint.

Q: What is the difference between direct equivalents and voltage upgrades?

A: Direct equivalents (50V rated) have identical electrical specifications to the main part. Voltage upgrades (100V, 200V, 250V) maintain the same capacitance and tolerance but provide higher voltage ratings. Voltage upgrades are electrically compatible with 50V applications and provide additional design margin. However, they may have different physical thickness specifications.

Q: Can I use KEMET C0805C103K5RAC7800 instead of Samsung CL21B103KBANNWC?

A: Yes. Both parts have identical electrical specifications (10000 pF, ±10%, 50V, X7R) and 0805 package footprint. KEMET C0805C103K5RAC7800 is supplied in Cut Tape (CT) & Digi-Reel® format. The thickness specification is 0.035" compared to 0.030" for the original part. Verify PCB assembly clearance before substitution.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant, REACH Unaffected, and classified as EAR99 for ECCN purposes. All parts maintain MSL 1 (Unlimited) moisture sensitivity level.

Q: What is the advantage of using CL21B103KCANNNC (100V) over the 50V rated part?

A: The 100V rated part provides additional voltage safety margin for circuit designs. It maintains identical capacitance (10000 pF) and tolerance (±10%) specifications. The 100V part is electrically compatible with applications rated for 50V and offers higher reliability margin. Inventory availability is significantly higher (876100 Pcs).

Q: Does thickness variation affect PCB assembly compatibility?

A: Yes. The main part specifies 0.030" maximum thickness. KEMET parts specify 0.035", and some voltage-upgraded parts specify 0.037" or 0.057" thickness. Verify PCB assembly equipment clearance specifications and reflow oven profile compatibility before selecting parts with increased thickness.

Q: Can YAGEO CC0805KRX7R9BB103 be used as a direct replacement?

A: Yes. YAGEO CC0805KRX7R9BB103 has identical electrical specifications (10000 pF, ±10%, 50V, X7R) and 0805 package footprint. It specifies 0.024" maximum thickness, which is thinner than the original part. All compliance certifications (ROHS3, MSL 1) are maintained.

Q: What packaging formats are available for direct equivalents?

A: Direct equivalents are available in Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® formats. Samsung CL21B103KBANNNC offers the highest inventory in Cut Tape format (240200 Pcs). KEMET C0805C103K5RAC7210 offers the highest inventory in Tape & Reel format (97585 Pcs) among KEMET options.
