Parameter Comparison

Engineering Selection Recommendations

Both VCAS120656F111DP and VC120656F111RP are active production parts from KYOCERA AVX with identical electrical specifications, mechanical packaging, and regulatory compliance. Selection between these parts is based on availability and supply chain requirements rather than technical performance differences.

VCAS120656F111DP is suitable for applications requiring the FLEXITERM® series designation with current inventory of 684 pieces.

VC120656F111RP is suitable for applications compatible with the TransGuard® series designation with higher current inventory of 11,375 pieces.

Both parts satisfy AEC-Q200 automotive qualification, ROHS3 compliance, and REACH unaffected status. Both maintain identical electrical performance across the specified operating temperature range of -55°C to 125°C and identical surge current handling of 100 A at 68 V nominal varistor voltage.

Frequently Asked Questions (FAQ)

Q: Can VC120656F111RP be used as a direct replacement for VCAS120656F111DP?

A: Yes. Both parts are electrically and mechanically identical with matching varistor voltage (68 V typical), surge current (100 A), package format (1206 / 3216 Metric), and regulatory compliance (AEC-Q200, ROHS3). The primary difference is the series designation (TransGuard® versus FLEXITERM®) and available inventory levels.

Q: Are there any differences in the 1206 package dimensions between these parts?

A: No. Both parts use the identical MLCV 1206 (3216 Metric) surface mount package format with identical mechanical specifications for PCB placement and reflow soldering.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both VCAS120656F111DP and VC120656F111RP carry AEC-Q200 automotive qualification and are suitable for automotive-grade applications.

Q: What is the difference between FLEXITERM® and TransGuard® series?

A: Both are KYOCERA AVX varistor product lines. The series designation reflects internal product categorization but does not affect electrical performance or mechanical compatibility for these specific part numbers.

Q: Are the moisture sensitivity levels identical?

A: Yes. Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. Identical electrical parameters, package format, and regulatory compliance allow direct substitution in PCB designs without circuit modification or re-qualification.
