VCAS080518C400RP Equivalent & Substitute Parts

Part Overview

The VCAS080518C400RP is a 25.5 V, 120 A Transient Voltage Suppressor (TVS) varistor manufactured by KYOCERA AVX in the TransGuard® series. This surface mount component in 0805 (2012 Metric) package is designed for transient voltage protection in electronic circuits. The part is currently Active in product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Substitute parts are identified to provide design flexibility, inventory optimization, and continuity of supply while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the VCAS080518C400RP are qualified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

• Varistor Voltage range (Min: 22.95 V, Typ: 25.5 V, Max: 28.05 V)
• Current - Surge rating (120 A)
• Maximum AC and DC voltage ratings (13 V AC, 18 V DC)
• Energy dissipation capability (0.3 J)
• Capacitance at 1 kHz (550 pF)
• Operating temperature range (-55°C to 125°C)
• Package and mounting specifications (0805 / 2012 Metric, Surface Mount MLCV)
• Compliance standards (ROHS3, MSL 1)

All identified substitute parts maintain these specifications without deviation. Differences in packaging codes (RP, DP, DZ, RZ suffixes) and series designations (TransGuard® vs. FLEXITERM®) do not affect electrical performance or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All four parts—VCAS080518C400RP, VCAS080518C400DP, VCAS080518C400DZ, and VCAS080518C400RZ—are Active products with identical electrical specifications and full compliance with ROHS3 and REACH standards. Selection among these equivalents may be based on inventory availability and packaging code requirements specific to procurement or manufacturing systems.

VCAS080518C400DZ carries additional AEC-Q200 automotive qualification, making it suitable for applications requiring automotive-grade component certification. This qualification does not alter the electrical or mechanical performance but indicates suitability for automotive environments.

All parts maintain MSL 1 (Unlimited) moisture sensitivity level, eliminating moisture-related handling constraints during assembly and storage.

Frequently Asked Questions (FAQ)

Q: Can VCAS080518C400DP be used as a direct replacement for VCAS080518C400RP?

A: Yes. Both parts are parametrically equivalent across all electrical and mechanical specifications. The suffix difference (RP vs. DP) reflects packaging code variations that do not affect circuit performance or PCB compatibility.

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

A: Both series are manufactured by KYOCERA AVX and meet identical electrical specifications for this part number. The series designation reflects internal product line organization but does not impact electrical performance, thermal characteristics, or mechanical compatibility.

Q: Is VCAS080518C400DZ suitable for automotive applications?

A: VCAS080518C400DZ carries AEC-Q200 automotive qualification. If your application requires automotive-grade component certification, this part meets that requirement. The other variants do not carry this specific qualification.

Q: Are all substitute parts available in the same package size?

A: Yes. All substitute parts use the 0805 (2012 Metric) surface mount package with MLCV mounting type. PCB footprints and assembly processes remain identical across all variants.

Q: What is the significance of the packaging code suffix (RP, DP, DZ, RZ)?

A: The suffix indicates the specific packaging configuration and tape format used for reel delivery. These differences are administrative and do not affect electrical performance, mechanical fit, or thermal characteristics. Selection is typically driven by procurement system requirements or inventory management practices.

Q: Do all parts have the same moisture sensitivity level?

A: Yes. All four parts carry MSL 1 (Unlimited), meaning they have no moisture sensitivity restrictions and do not require special dry-pack handling or baking procedures prior to assembly.

Q: Can these parts be used interchangeably in production?

A: Yes, provided your procurement and manufacturing systems can accommodate the different part numbers. All parts are electrically and mechanically identical and will perform identically in the circuit.
