Substitute Part Grouping Explanation

Substitution logic for the C1206C223K4RACTU is based on the following criteria:

Identical Parameters (Non-Negotiable):

• Capacitance value: 0.022 µF
• Tolerance: ±10%
• Temperature coefficient: X7R
• Package: 1206 (3216 Metric)
• Mounting type: Surface Mount, MLCC
• Operating temperature range: -55°C to 125°C
• Moisture sensitivity: MSL 1

Allowable Variation:

• Voltage rating may be increased above the 16V specification, provided the substitute part maintains all other electrical and mechanical parameters

The substitute part C1206C223K5RAC7800 meets all identical parameter requirements and provides an elevated voltage rating of 50V, making it suitable for applications requiring higher voltage margin or in circuits where the supply voltage may exceed the original 16V specification.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (C1206C223K4RACTU): Use the original part number when the circuit design specifies a 16V rated capacitor and inventory availability permits. This part is in active production status with ROHS3 compliance and MSL 1 rating, suitable for standard bypass and decoupling applications.

Substitute Part Selection (C1206C223K5RAC7800): The substitute part C1206C223K5RAC7800 is electrically and mechanically compatible with the original specification. The 50V voltage rating provides additional safety margin in applications where supply voltage stability or transient conditions may approach the original 16V limit. Both parts maintain identical capacitance, tolerance, temperature coefficient, package dimensions, and compliance certifications. The substitute part has significantly higher inventory availability (161,844 pieces versus 770 pieces), making it suitable for high-volume production or supply chain continuity scenarios.

Both parts are manufactured by KEMET, maintain ROHS3 compliance, and carry MSL 1 moisture sensitivity rating, ensuring compatibility with standard surface mount assembly processes.

Frequently Asked Questions (FAQ)

Q: Can C1206C223K5RAC7800 be used as a direct replacement for C1206C223K4RACTU?

A: Yes. The substitute part maintains identical capacitance (0.022 µF), tolerance (±10%), temperature coefficient (X7R), package dimensions (1206 / 3216 Metric), and operating temperature range (-55°C to 125°C). The increased voltage rating (50V versus 16V) does not create incompatibility; it provides additional voltage margin. Both parts are surface mount MLCCs with identical physical footprints and mounting requirements.

Q: What is the difference between the 16V and 50V ratings?

A: The voltage rating indicates the maximum DC voltage the capacitor can withstand without dielectric breakdown. A 50V-rated capacitor can safely operate at any voltage up to 50V, including 16V circuits. The 50V rating provides additional safety margin and may be beneficial in applications with voltage transients or where supply voltage stability is uncertain.

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). They are mechanically interchangeable on PCB assemblies without requiring layout modifications or requalification of solder reflow profiles.

Q: Do both parts meet the same compliance standards?

A: Yes. Both C1206C223K4RACTU and C1206C223K5RAC7800 are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and are REACH unaffected. They are suitable for identical manufacturing and assembly processes.

Q: Which part should be selected for new designs?

A: Selection depends on circuit requirements and supply chain considerations. If the circuit design specifies 16V operation with no anticipated voltage transients, either part is acceptable. If higher voltage margin is desired or if C1206C223K5RAC7800 offers better inventory availability for production timelines, the 50V-rated substitute is the appropriate choice. Both parts are in active production status.

Q: Are there any thermal or frequency performance differences?

A: Both parts share identical X7R temperature coefficient characteristics and operate across the same -55°C to 125°C temperature range. No performance differences are introduced by substitution in bypass and decoupling applications.
