Parameter Comparison

Engineering Selection Recommendations

All three parts—VCAS120645K900TP, VCAS120645K900DP, and VCAS120645K900DZ—are Active products from KYOCERA AVX with full RoHS3 compliance and unlimited moisture sensitivity level (MSL 1). Each part meets REACH requirements and is classified as EAR99 for export purposes.

The VCAS120645K900DZ provides an additional qualification advantage with AEC-Q200 certification, making it suitable for automotive-grade applications requiring formal qualification documentation. The VCAS120645K900DP and VCAS120645K900TP are functionally equivalent without automotive-specific certification.

Component selection should be based on supply chain availability and compliance requirements specific to the application. All three parts deliver identical electrical performance in TVS transient voltage suppression applications.

Frequently Asked Questions (FAQ)

Q: Can VCAS120645K900DP be used as a direct replacement for VCAS120645K900TP? A: Yes. Both parts share identical varistor voltage ratings (56 V typical), surge current capacity (200 A), energy rating (0.6 J), and are housed in the same 1206 (3216 Metric) package format. Electrical and mechanical compatibility is complete.

Q: What is the difference between VCAS120645K900TP and VCAS120645K900DZ? A: The primary difference is that VCAS120645K900DZ carries AEC-Q200 automotive qualification certification. All electrical parameters, varistor voltage ranges (50.4 V - 61.6 V), surge ratings, energy levels, and package specifications are identical. The FLEXITERM® series designation indicates automotive-grade material and processing.

Q: Are all substitute parts compatible with the same PCB footprint? A: Yes. All three parts use Surface Mount, MLCV mounting technology in the 1206 (3216 Metric) package case. PCB layout and assembly processes are directly interchangeable.

Q: Which part should be selected for automotive applications? A: VCAS120645K900DZ is qualified to AEC-Q200 automotive standards. The other parts are suitable for general industrial and consumer electronics applications where automotive-grade certification is not required.

Q: Do all substitute parts have the same tape and reel packaging? A: Yes. All three parts are supplied in Tape & Reel (TR) format, enabling compatibility with standard pick-and-place assembly equipment.

Q: What is the voltage operating range for circuit protection? A: Maximum DC operating voltage is 45 V and maximum AC operating voltage is 35 V across all three part numbers. The typical varistor voltage clamps at 56 V with a tolerance range of 50.4 V (minimum) to 61.6 V (maximum).
