Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CL21B102KECSW6C are classified into two categories based on electrical parameter matching:

Direct Equivalents (Identical Electrical Specifications): Parts that match all critical electrical parameters: 1000 pF capacitance, ±10% tolerance, 250V rated voltage, X7R temperature coefficient, and -55°C ~ 125°C operating temperature range. These parts are interchangeable without circuit redesign.

Upgrade Substitute (Enhanced Voltage Rating): Parts that maintain identical capacitance, tolerance, temperature coefficient, and operating temperature range but feature increased voltage rating (500V instead of 250V). These parts provide higher voltage margin and are suitable for applications where increased voltage headroom is beneficial.

All substitute parts share the following critical parameters with the main part:

• Capacitance: 1000 pF
• Tolerance: ±10%
• Temperature Coefficient: X7R
• Operating Temperature: -55°C ~ 125°C
• Package: 0805 (2012 Metric)
• Mounting Type: Surface Mount, MLCC
• Features: Soft Termination
• RoHS Status: ROHS3 Compliant
• MSL: 1 (Unlimited)

Engineering Selection Recommendations

For Direct Replacement: C0805X102KARAC7800 (KEMET), C2012X7R2E102K085AE (TDK Corporation), and CS0805KRX7RYBB102 (YAGEO) are direct electrical and mechanical equivalents to CL21B102KECSW6C. All parts maintain identical capacitance, tolerance, voltage rating, temperature coefficient, and operating temperature specifications. All substitute parts are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (Unlimited), matching the compliance profile of the main part.

For Enhanced Voltage Margin: CS0805KRX7RBBB102 (YAGEO) provides the same capacitance, tolerance, and temperature characteristics as the main part but with 500V rated voltage instead of 250V. This upgrade substitute is suitable for applications requiring increased voltage headroom while maintaining all other electrical and mechanical specifications. This part is also ROHS3 compliant and MSL 1 (Unlimited).

Inventory Availability: Direct equivalents are available in varying stock quantities: C0805X102KARAC7800 (5401 Pcs), C2012X7R2E102K085AE (1641 Pcs), and CS0805KRX7RYBB102 (11056 Pcs). The upgrade substitute CS0805KRX7RBBB102 is available with 2600 Pcs in stock.

Frequently Asked Questions (FAQ)

Q: Can C0805X102KARAC7800 replace CL21B102KECSW6C directly? A: Yes. C0805X102KARAC7800 is a direct equivalent with identical electrical specifications (1000 pF, ±10%, 250V, X7R, -55°C ~ 125°C) and mechanical package (0805). Both parts feature soft termination and are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between the direct equivalents and CS0805KRX7RBBB102? A: The direct equivalents (C0805X102KARAC7800, C2012X7R2E102K085AE, CS0805KRX7RYBB102) are rated for 250V, matching the main part. CS0805KRX7RBBB102 is rated for 500V, providing double the voltage rating while maintaining all other specifications. This upgrade substitute is suitable for circuits requiring higher voltage margin.

Q: Are all substitute parts compatible with the 0805 package footprint? A: Yes. All substitute parts use the 0805 (2012 Metric) package with identical footprint dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm). Thickness variations are minimal (0.95mm to 1.00mm maximum) and do not affect PCB assembly compatibility.

Q: Do the substitute parts meet the same compliance requirements? A: Yes. All substitute parts are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (Unlimited), matching the compliance profile of CL21B102KECSW6C. All parts carry the same ECCN (EAR99) and HTSUS (8532.24.0020) classifications.

Q: Which substitute part should be selected for boardflex-sensitive applications? A: All substitute parts feature soft termination and are specified for boardflex-sensitive applications, identical to the main part. Selection can be based on voltage requirement (250V or 500V), manufacturer preference, or inventory availability.

Q: Can CS0805KRX7RBBB102 be used in a circuit designed for 250V operation? A: Yes. CS0805KRX7RBBB102 is rated for 500V and can be used in circuits designed for 250V operation. The higher voltage rating provides additional safety margin and does not degrade performance in lower-voltage applications.
