Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the VCAS120605D150RP are identified through strict parametric equivalence. All substitute candidates maintain identical electrical specifications: 8.5 V typical varistor voltage (6.8 to 10.2 V range), 150 A surge current, 0.4 J energy absorption, and 3000 pF capacitance at 1 kHz. All substitutes operate across the same temperature range (-55°C to 125°C) and use the identical 1206 (3216 Metric) surface mount package with single-circuit configuration.

Substitution logic is based on the following key parameters:

• Varistor voltage specification (6.8 to 10.2 V range)
• Surge current rating (150 A)
• Energy absorption capacity (0.4 J)
• Package form factor (1206 MLCV surface mount)
• Operating temperature range (-55°C to 125°C)
• Compliance certifications (AEC-Q200, RoHS3)

Differences among substitute parts are limited to packaging format (Tape & Reel versus Cut Tape & Digi-Reel®) and inventory availability. All substitute parts are manufactured by KYOCERA AVX within the TransGuard® series and maintain active product status.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed—VC120605D150DP, VC120605D150RP, and VCAS120605D150DP—are direct parametric equivalents to the VCAS120605D150RP. Selection among these parts is determined by packaging and supply requirements rather than electrical performance.

Packaging Considerations:

• Tape & Reel (TR) Format: VCAS120605D150RP and VCAS120605D150DP are supplied in Tape & Reel packaging, suitable for high-volume automated assembly operations.
• Cut Tape (CT) & Digi-Reel® Format: VC120605D150DP and VC120605D150RP are supplied in Cut Tape and Digi-Reel® packaging, suitable for lower-volume or mixed-component procurement scenarios.

Compliance and Certification:

All substitute parts maintain identical compliance profiles: AEC-Q200 automotive qualification, RoHS3 compliance, REACH unaffected status, and Moisture Sensitivity Level 1 (unlimited shelf life). All parts are actively produced by KYOCERA AVX and suitable for automotive and industrial applications requiring transient overvoltage protection.

Series Designation:

The VCAS120605D150RP is designated within the FLEXITERM® series, while all substitute parts are designated within the TransGuard® series. Both series are manufactured by KYOCERA AVX and maintain equivalent electrical and thermal performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can VC120605D150DP be used as a direct replacement for VCAS120605D150RP in PCB assembly?

A: Yes. Both parts share identical electrical specifications (8.5 V varistor voltage, 150 A surge current, 0.4 J energy), operate across the same temperature range (-55°C to 125°C), and use the same 1206 (3216 Metric) surface mount package. The primary difference is packaging format: VC120605D150DP uses Cut Tape & Digi-Reel® while VCAS120605D150RP uses Tape & Reel. Both are compatible with standard surface mount assembly equipment.

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

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on a reel, optimized for high-speed automated pick-and-place assembly. Cut Tape (CT) & Digi-Reel® packaging supplies components on cut tape segments or alternative reel formats, suitable for lower-volume orders or mixed-component kits. Electrical and mechanical performance are identical; packaging choice depends on assembly volume and equipment compatibility.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. VCAS120605D150RP, VC120605D150DP, VC120605D150RP, and VCAS120605D150DP all carry AEC-Q200 automotive qualification and are suitable for automotive-grade applications requiring transient voltage suppression.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: All parts are rated MSL 1 (Unlimited), indicating unlimited shelf life without moisture bake-out requirements. These components can be stored and handled under standard warehouse conditions without special moisture control measures.

Q: Can these varistors be used in both AC and DC circuits?

A: Yes. All parts are rated for maximum DC voltage of 5.6 V and maximum AC voltage of 4 V, with typical varistor voltage of 8.5 V. Circuit design must ensure applied voltages remain within these specified limits.

Q: What is the energy absorption capacity of these parts?

A: All substitute parts absorb 0.4 J of transient energy. This specification determines the maximum energy level the varistor can safely dissipate during a single transient event without degradation.

Q: Are there any differences in capacitance between the main part and substitutes?

A: No. All parts maintain 3000 pF capacitance at 1 kHz, ensuring consistent high-frequency performance in transient suppression circuits.
