Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KAS15AR71H222KT is determined by strict equivalence across the following parameters:

Electrical Specifications: Capacitance value (2200 pF), tolerance (±10%), rated voltage (50V), and temperature coefficient (X7R) must be identical.

Mechanical Compatibility: Package designation (0603/1608 Metric), physical dimensions (0.063" L x 0.032" W, 1.60mm x 0.81mm), and maximum thickness (0.035"/0.90mm) must match exactly for PCB footprint compatibility.

Compliance & Ratings: AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 classification must be maintained.

Mounting & Termination: Surface mount MLCC configuration with soft termination feature must be preserved.

The substitute part KAF15AR71H222KT meets all these criteria and is classified as a parametric equivalent within the KYOCERA AVX FLEXITERM product family.

Parameter Comparison

Engineering Selection Recommendations

Both KAS15AR71H222KT and KAF15AR71H222KT are active production parts from KYOCERA AVX with full AEC-Q200 automotive qualification. Selection between these parts is based on inventory availability and supply chain requirements rather than technical differentiation.

KAS15AR71H222KT carries 4781 pieces in current inventory, while KAF15AR71H222KT has 88503 pieces available. Both parts maintain ROHS3 compliance and MSL 1 classification, indicating no moisture sensitivity constraints during storage and handling.

The identical electrical specifications (2200 pF, ±10%, 50V, X7R) and mechanical dimensions (0603 package, 1.60mm x 0.81mm, 0.90mm thickness) ensure direct PCB footprint compatibility and circuit performance equivalence. The soft termination feature is present in both variants, supporting boardflex-sensitive applications.

Frequently Asked Questions (FAQ)

Q: Can KAF15AR71H222KT be used as a direct replacement for KAS15AR71H222KT?

A: Yes. Both parts are parametric equivalents with identical capacitance (2200 pF), tolerance (±10%), voltage rating (50V), temperature coefficient (X7R), package (0603/1608 Metric), and physical dimensions. They are interchangeable at the circuit and PCB assembly level.

Q: Are there any differences in automotive qualification between these parts?

A: No. Both parts carry AEC-Q200 rating, confirming automotive-grade reliability and qualification. Operating temperature range (-55°C ~ 125°C) is identical for both.

Q: What is the significance of the soft termination feature?

A: Soft termination reduces mechanical stress on component leads during PCB flexing and thermal cycling. Both KAS15AR71H222KT and KAF15AR71H222KT include this feature, making them suitable for boardflex-sensitive applications.

Q: Do these parts require different handling or storage procedures?

A: No. Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity. Standard ESD precautions apply to both, and they can be stored under identical conditions.

Q: What is the difference between the KAS and KAF part number prefixes?

A: The prefix difference reflects internal KYOCERA AVX product family designations within the FLEXITERM series. The KAS variant belongs to FLEXITERM™ Flexisafe, while KAF belongs to FLEXITERM®. Electrical and mechanical specifications remain identical.

Q: Can these capacitors be used in non-automotive applications?

A: Yes. AEC-Q200 qualification exceeds standard commercial requirements, making these parts suitable for industrial, consumer, and other non-automotive applications requiring 2200 pF, 50V ceramic capacitors in 0603 packages.

Q: What is the ROHS3 compliance status?

A: Both parts are ROHS3 compliant, confirming restriction of hazardous substances in accordance with EU Directive 2011/65/EU and its amendments.
