Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C1206C104F8JAC7800 is determined by strict equivalence in the following parameters:

Mandatory Equivalence Parameters:

• Capacitance: 0.1 µF (exact match required)
• Tolerance: ±1% (exact match required)
• Temperature Coefficient: U2J (exact match required)
• Package / Case: 1206 (3216 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)

Allowable Variation Parameters:

• Voltage - Rated: May be equal to or greater than the original 10V rating

The substitute part C1206C104F5JAC7800 maintains identical capacitance, tolerance, temperature coefficient, package dimensions, and operating temperature range. The voltage rating is increased from 10V to 50V, which is an allowable upward variation that does not compromise circuit compatibility when the application voltage requirement does not exceed 50V.

Parameter Comparison

Engineering Selection Recommendations

C1206C104F8JAC7800 (10V Rating): Select this part when circuit design specifies a maximum operating voltage of 10V and component cost optimization is prioritized. Both main and substitute parts maintain Active product status with full ROHS3 compliance and unlimited moisture sensitivity rating, ensuring equivalent reliability and regulatory compliance.

C1206C104F5JAC7800 (50V Rating): Select this part when circuit design requires voltage margin above 10V or when application conditions may expose the capacitor to transient overvoltage conditions. The 50V rating provides increased safety margin while maintaining identical capacitance, tolerance, temperature coefficient, and physical dimensions. This substitute is suitable for direct replacement in existing PCB layouts without design modification. Higher inventory availability (8220 units) may support supply chain continuity.

Both parts are manufactured by KEMET under the SMD Comm U2J series with identical mechanical compatibility and thermal performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can C1206C104F5JAC7800 directly replace C1206C104F8JAC7800 on existing PCBs?

A: Yes. Both parts share identical 1206 (3216 Metric) package dimensions, footprint requirements, and mounting specifications. No PCB layout modification is required. The substitute part occupies the same physical space and connects to identical pad patterns.

Q: What is the significance of the voltage rating difference between 10V and 50V?

A: The voltage rating indicates the maximum continuous DC voltage the capacitor can withstand. The 50V-rated substitute provides higher voltage margin and is suitable for circuits operating at or below 10V. Selection depends on circuit maximum voltage exposure, not on capacitance or tolerance requirements.

Q: Are the capacitance and tolerance values identical between both parts?

A: Yes. Both C1206C104F8JAC7800 and C1206C104F5JAC7800 provide 0.1 µF capacitance with ±1% tolerance. Electrical performance in terms of capacitive value is identical.

Q: Do both parts operate across the same temperature range?

A: Yes. Both parts operate from -55°C to 125°C with U2J temperature coefficient characteristics. Thermal performance and temperature stability are equivalent.

Q: What does the U2J temperature coefficient indicate?

A: U2J is a standardized temperature coefficient classification for ceramic capacitors indicating specific capacitance change characteristics across the operating temperature range. Both parts share identical U2J classification, ensuring equivalent temperature-dependent behavior.

Q: Are there any compliance or regulatory differences between the two parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (Unlimited moisture sensitivity). Regulatory and environmental compliance status is identical.

Q: Which part should be selected for new designs?

A: Selection is based on circuit voltage requirements. If maximum circuit voltage is 10V or below, either part is acceptable. If voltage margin or future design flexibility is required, the 50V-rated C1206C104F5JAC7800 is appropriate. Both parts are Active status with equivalent reliability.
