Parameter Comparison

Engineering Selection Recommendations

All four parts—VCAS120618D400DP, VC120618D400DP, VCAS120618D400DZ, and VCAS120618D400RP—are direct electrical and mechanical equivalents. Selection between them is determined by packaging and distribution requirements:

VCAS120618D400DP (Original Part): Tape & Reel packaging. Suitable for high-volume automated assembly operations.

VC120618D400DP: Cut Tape & Digi-Reel® packaging. Appropriate for moderate-volume production or mixed component sourcing.

VCAS120618D400DZ: Tape & Reel packaging with FLEXITERM® series designation and AEC-Q200 automotive qualification. Select when automotive-grade certification is required.

VCAS120618D400RP: Cut Tape & Digi-Reel® packaging. Suitable for moderate-volume production or component kitting scenarios.

All parts maintain active production status, ROHS3 compliance, and unlimited moisture sensitivity rating (MSL 1), ensuring long-term availability and environmental regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can VCAS120618D400DP be replaced with VC120618D400DP?

A: Yes. Both parts are electrically and mechanically identical with 25.5 V typical varistor voltage, 150 A surge current, and 1206 package. The difference is packaging format: VCAS120618D400DP uses Tape & Reel, while VC120618D400DP uses Cut Tape & Digi-Reel®. Selection depends on assembly process requirements.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel® packaging?

A: Tape & Reel (TR) is continuous reel packaging optimized for high-speed automated pick-and-place assembly. Cut Tape (CT) & Digi-Reel® provides individual tape segments suitable for lower-volume production, manual assembly, or component kitting. Electrical performance is identical.

Q: Is VCAS120618D400DZ suitable for automotive applications?

A: Yes. VCAS120618D400DZ carries AEC-Q200 automotive qualification and FLEXITERM® series designation, meeting automotive-grade requirements. It maintains identical electrical specifications (25.5 V, 150 A, 0.4 J) as the standard TransGuard® series parts.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All four parts—VCAS120618D400DP, VC120618D400DP, VCAS120618D400DZ, and VCAS120618D400RP—are ROHS3 compliant and REACH unaffected, meeting current environmental regulatory requirements.

Q: What is the operating temperature range for these varistors?

A: All substitute parts operate across -55°C to 125°C (TA), providing consistent thermal performance across standard industrial and commercial temperature ranges.

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

A: Yes. All parts use identical 1206 (3216 Metric) surface mount package and MLCV mounting type. PCB footprints and assembly processes remain unchanged across all substitutes.
