Engineering Selection Recommendations

All three part numbers are functionally equivalent for transient voltage suppression applications. Component selection should be based on availability and procurement considerations:

VCAS120626D580TP - Primary part number with 922 units currently in stock. Suitable for immediate procurement and standard applications requiring automotive-grade transient voltage suppression.

VC120626D580DP - Direct parametric equivalent with 2,320 units in inventory. Provides higher stock availability for applications with extended procurement timelines or higher volume requirements.

VC120626D580RP - Parametric equivalent with 4,060 units in stock, representing the highest available inventory position. Recommended for high-volume production or applications requiring the longest supply chain visibility.

All variants maintain full AEC-Q200 automotive qualification and ROHS3 compliance, suitable for automotive and industrial transient voltage protection circuits operating within the specified -55°C to 125°C temperature range.

Frequently Asked Questions (FAQ)

Q: Are VC120626D580DP and VC120626D580RP true substitutes for VCAS120626D580TP?

A: Yes. Both parts meet all electrical and mechanical specifications of the VCAS120626D580TP, including varistor voltage rating (34.5 V typical), surge current (120 A), energy absorption (0.4 J), package size (1206 3216 Metric), and operating temperature range (-55°C to 125°C). All parts are manufactured by KYOCERA AVX within the TransGuard® series with active product status.

Q: Can I use these substitutes on existing PCBs designed for VCAS120626D580TP?

A: Yes. The substitute parts share identical package dimensions (1206 3216 Metric) and mounting type (surface mount MLCV), enabling direct PCB placement without layout modifications. Electrical performance is identical across all three part numbers.

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

A: The part number variations represent different internal designation or tape and reel configurations from KYOCERA AVX. Functionally and electrically, the three parts are identical. Differences are limited to inventory classification and supply chain designation.

Q: Are there any compliance differences between these parts?

A: No. All three parts are ROHS3 compliant, REACH unaffected, AEC-Q200 qualified, and carry moisture sensitivity level 1 (unlimited). Regulatory and environmental compliance status is identical.
