Parameter Comparison

Engineering Selection Recommendations

Both the 03063C102KAT2S and KGL15ZR71E102KT are active production parts from KYOCERA AVX with full ROHS3 compliance and identical electrical specifications. Selection between these parts should be based on:

Availability and Lead Time: The KGL15ZR71E102KT currently maintains higher inventory levels (3188 pcs) compared to the 03063C102KAT2S (851 pcs), making it suitable for applications requiring immediate procurement or larger volume requirements.

Physical Dimensions: The KGL15ZR71E102KT has a maximum thickness of 0.024" (0.61mm) compared to 0.022" (0.56mm) for the 03063C102KAT2S. This 0.002" difference is within typical PCB assembly tolerances and does not affect functional performance or board-level compatibility for standard surface mount applications.

Regulatory Compliance: Both parts maintain identical ROHS3 compliance, REACH unaffected status, and EAR99 ECCN classification, ensuring equivalent regulatory acceptance across all markets.

Frequently Asked Questions (FAQ)

Q: Can KGL15ZR71E102KT be used as a direct replacement for 03063C102KAT2S in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters including capacitance, voltage rating, temperature coefficient, package size, and mounting type. The 0.002" thickness difference does not impact PCB assembly or circuit performance.

Q: Are there any differences in the X7R temperature coefficient performance between these parts?

A: No. Both parts utilize identical X7R temperature coefficient characteristics and operate across the same temperature range of -55°C to 125°C with equivalent capacitance stability.

Q: What is the significance of the "Low ESL (Reverse Geometry)" feature?

A: Low ESL (Equivalent Series Inductance) design reduces parasitic inductance in the capacitor, improving high-frequency performance in bypass and decoupling applications. Both parts incorporate this feature identically.

Q: Are moisture handling and storage requirements the same for both parts?

A: Yes. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity limitations. Standard dry storage conditions apply to both parts equally.

Q: Can these parts be mixed in the same production batch or assembly?

A: Yes. Both parts are functionally and mechanically equivalent and can be used interchangeably within the same circuit design and PCB layout without modification.

Q: What is the difference between the two part numbers?

A: The part numbers reflect different internal KYOCERA AVX product line designations. The 03063C102KAT2S and KGL15ZR71E102KT represent equivalent products from different manufacturing or distribution channels within KYOCERA AVX, but maintain identical electrical and mechanical specifications.
