Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LD03ZC224KAB2C is determined by the following critical parameters:

• Capacitance Value: Must be 0.22 µF
• Tolerance: Must be ±10%
• Temperature Coefficient: Must be X7R
• Package / Case: Must be 0603 (1608 Metric)
• Mounting Type: Must be Surface Mount, MLCC
• Operating Temperature Range: Must support -55°C ~ 125°C

Substitute parts are grouped into two categories:

Direct Equivalent: Parts with identical electrical ratings (10V) and packaging specifications from the same or different manufacturers.

Upgrade Equivalent: Parts with higher voltage ratings (16V) that maintain all other electrical and mechanical specifications, providing enhanced design margin while remaining mechanically and electrically compatible.

Parameter Comparison

Engineering Selection Recommendations

LD03ZC224KAB2A is a direct equivalent substitute manufactured by KYOCERA AVX with identical electrical specifications and mechanical dimensions. Both the main part and this substitute maintain the same 10V rating, X7R temperature coefficient, and 0603 package footprint. Selection between LD03ZC224KAB2C and LD03ZC224KAB2A depends on packaging requirements and inventory availability. LD03ZC224KAB2A is supplied in Tape & Reel format with higher inventory availability (10,885 pieces).

C0603C224K4RAL7867 is an upgrade equivalent manufactured by KEMET with a higher 16V voltage rating while maintaining all other electrical and mechanical specifications. This part is suitable for applications where increased voltage margin is beneficial. The upgrade part has marginally reduced thickness (0.034" vs 0.035") and width (0.031" vs 0.032"), which remain within acceptable PCB layout tolerances for 0603 package footprints. Both substitute parts are active products with established supply chains.

Frequently Asked Questions (FAQ)

Q: Can LD03ZC224KAB2A be used as a direct replacement for LD03ZC224KAB2C?

A: Yes. Both parts share identical electrical specifications (0.22 µF, ±10%, 10V, X7R) and mechanical dimensions (0603 package). The primary difference is packaging format: LD03ZC224KAB2A is supplied in Tape & Reel, while LD03ZC224KAB2C packaging is not specified. Both are manufactured by KYOCERA AVX and are active products.

Q: What is the advantage of using C0603C224K4RAL7867 over the main part?

A: C0603C224K4RAL7867 provides a higher voltage rating (16V vs 10V) while maintaining the same capacitance value, tolerance, temperature coefficient, and package footprint. This upgrade allows for greater design margin in applications where voltage stress is a consideration. The part is mechanically compatible with 0603 PCB layouts.

Q: Are there any dimensional differences between these parts?

A: Dimensional differences are minimal. C0603C224K4RAL7867 has a slightly reduced thickness (0.034" vs 0.035") and width (0.031" vs 0.032") compared to the main part. These variations are within standard 0603 package tolerances and do not affect PCB assembly compatibility.

Q: What is the significance of the X7R temperature coefficient?

A: X7R indicates a temperature coefficient of ±15% over the -55°C to 125°C operating range. This specification ensures stable capacitance performance across the full operating temperature range, making these parts suitable for general purpose applications requiring predictable electrical behavior across temperature extremes.

Q: Are all three parts RoHS compliant?

A: No. LD03ZC224KAB2C and LD03ZC224KAB2A are both RoHS non-compliant. C0603C224K4RAL7867 is also RoHS non-compliant. All three parts are REACH Affected or REACH Unaffected as specified by their respective manufacturers.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: All three parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These parts can be stored and handled without special moisture control measures.
