Key Parameters

Substitute Part Grouping Explanation

Substitution of the C1206C104F4JAC7800 is permitted only when the following conditions are met:

Mandatory Identical Parameters:

• Capacitance: 0.1 µF
• Tolerance: ±1%
• Temperature Coefficient: U2J
• Operating Temperature Range: -55°C ~ 125°C
• Package / Case: 1206 (3216 Metric)
• Mounting Type: Surface Mount, MLCC
• RoHS Status: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

Allowable Variation:

• Voltage Rating: May be increased above 16V without affecting circuit function, provided the higher voltage rating does not introduce undesirable parasitic effects or cost inefficiencies in the specific application context.

The substitute part C1206C104F5JAC7800 meets all mandatory identical parameters and features an elevated voltage rating of 50V, which is acceptable for direct substitution in applications where the original 16V rating is sufficient.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: C1206C104F4JAC7800

Use the primary part when:

• Circuit design specifies 16V rated capacitors
• Inventory availability is confirmed
• Cost optimization favors the lower voltage rating

Substitute Part: C1206C104F5JAC7800

Use the substitute part when:

• Primary part inventory is unavailable
• Circuit design permits 50V rated capacitors
• Higher voltage margin is beneficial for reliability
• Both parts maintain identical compliance certifications (ROHS3, REACH Unaffected)

Both parts are Active status products from KEMET with identical electrical characteristics except for voltage rating. Selection between them depends solely on circuit voltage requirements and availability. No additional testing or verification is required for substitution within the specified parameters.

Frequently Asked Questions (FAQ)

Q: Can C1206C104F5JAC7800 replace C1206C104F4JAC7800 in any application?

A: Yes, provided the circuit design permits a 50V rated capacitor. The higher voltage rating does not affect capacitance, tolerance, temperature coefficient, or physical dimensions. All other electrical and mechanical parameters are identical.

Q: What is the significance of the voltage rating difference?

A: The voltage rating indicates the maximum DC voltage the capacitor can withstand. A 50V rated capacitor can be used in circuits designed for 16V operation. The higher rating provides additional voltage margin but does not change the capacitor's behavior at lower voltages.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts use the 1206 (3216 Metric) package with dimensions of 0.126" L x 0.063" W (3.20mm x 1.60mm) and maximum thickness of 0.035" (0.88mm). They are mechanically interchangeable on PCBs.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both C1206C104F4JAC7800 and C1206C104F5JAC7800 are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the temperature coefficient U2J?

A: U2J is the temperature coefficient classification for these ceramic capacitors, indicating their capacitance change over the operating temperature range of -55°C to 125°C. Both parts share identical temperature stability characteristics.

Q: Can these parts be used interchangeably in automated assembly?

A: Yes. Both parts are surface mount MLCCs in identical 1206 packages with identical tape and reel packaging. They are compatible with standard pick-and-place assembly equipment without modification.

Q: What is MSL 1 rating?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture bake-out requirements. Both parts can be stored and handled without special moisture control procedures.
