Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C2012JB1C226M085AC is determined by the following critical parameters:

Primary Substitution Criteria:

• Capacitance: 22 µF (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• Voltage Rating: 16V or higher (equal or greater voltage rating acceptable)
• Tolerance: ±20% or tighter (equal or tighter tolerance acceptable)
• Mounting Type: Surface Mount, MLCC (exact match required)
• RoHS Compliance: ROHS3 Compliant (required)
• Moisture Sensitivity: MSL 1 (required)

Secondary Consideration:

• Temperature Coefficient: JB or X5R or X6S (different coefficients acceptable if operating temperature range meets or exceeds -25°C ~ 85°C requirement)

The substitute parts listed below meet all primary criteria and maintain functional compatibility with the original specification.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: C2012X5R1C226M125AC

This TDK part is the most direct substitute. It maintains 22 µF capacitance, ±20% tolerance, and 16V rating with Active product status. The X5R temperature coefficient provides -55°C to 85°C operating range, exceeding the original -25°C to 85°C requirement. ROHS3 compliance and MSL 1 rating are confirmed. High inventory availability (500300 Pcs) ensures procurement reliability.

Secondary Recommendation: C2012X6S1C226M125AC

This TDK part offers identical electrical specifications with X6S temperature coefficient, extending operating range to -55°C ~ 105°C. Active product status and substantial inventory (736048 Pcs) support long-term availability. Suitable for applications requiring extended high-temperature performance.

Alternative for Tighter Tolerance: C2012X5R1C226K125AC

This part provides ±10% tolerance (tighter than ±20%) with identical 22 µF, 16V specifications. Product status is Not For New Designs; use only when tighter tolerance is functionally required and inventory constraints permit.

Cross-Manufacturer Option: CL21A226MOCLRNC

Samsung Electro-Mechanics equivalent with matching 22 µF, ±20%, 16V, X5R specifications. Active product status and 181300 Pcs inventory provide alternative sourcing. Thickness matches original at 0.037".

Not Recommended: CL21A226MQQNNNE

This part has 6.3V rating, insufficient for 16V application requirement. Voltage rating is a critical parameter and cannot be downrated.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with higher voltage rating than the original 16V specification?

A: Yes. Higher voltage ratings are acceptable substitutes. Parts rated 25V (C2012X5R1E226M125AC) or 35V (C2012X5R1V226M125AC) will function in circuits designed for 16V operation. The capacitor will not be stressed and reliability is maintained.

Q: What is the difference between JB, X5R, and X6S temperature coefficients?

A: These designate different capacitance stability characteristics across temperature ranges. JB operates -25°C ~ 85°C. X5R operates -55°C ~ 85°C with tighter capacitance tolerance over temperature. X6S operates -55°C ~ 105°C. All three are acceptable substitutes if the operating temperature range of your application falls within the part's specification.

Q: Does the thickness difference between 0.037" and 0.057" affect compatibility?

A: Thickness differences do not affect electrical function. Verify PCB layout clearance for components adjacent to the capacitor. The 0.037" thickness (CL21A226MOCLRNC, original C2012JB1C226M085AC) provides lower profile; the 0.057" thickness parts are standard height for 0805 packages.

Q: Why is CL21A226MQQNNNE listed if it has 6.3V rating?

A: This part does not meet substitution criteria due to insufficient voltage rating. It is included in the data set but is not a valid substitute for 16V applications.

Q: Can I substitute based on capacitance value alone?

A: No. Voltage rating, package, tolerance, and compliance certifications must all match or exceed original specifications. Capacitance matching is necessary but not sufficient for valid substitution.

Q: What does "Not For New Designs" product status mean?

A: This status indicates the manufacturer is phasing out the part. It remains available but is not recommended for new circuit designs. Use Active status parts (C2012X5R1C226M125AC, C2012X5R1E226M125AC, C2012X6S1C226M125AC, CL21A226MOCLRNC) for new designs.
