VCAS080518A400RP Equivalent & Substitute Parts

Part Overview

The VCAS080518A400RP is a 25.5 V 30 A Transient Voltage Suppressor (TVS) varistor manufactured by KYOCERA AVX in the FLEXITERM® series. This surface mount component operates in the 0805 (2012 Metric) package and is designed for automotive-grade applications with AEC-Q200 qualification. The device provides transient voltage suppression across a single circuit with 0.1 J energy rating and 225 pF capacitance at 1 kHz. The part is currently active in production with 56,300 units in stock and is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified when component availability changes, supply chain disruptions occur, or design flexibility is required while maintaining identical electrical and mechanical performance within specified parameter tolerances.

Substitute Part Grouping Explanation

Substitution of the VCAS080518A400RP is permissible with parts that maintain identical electrical specifications across all critical parameters. The substitution logic is based on the following criteria:

Electrical Parameters (Must Match):

• Varistor voltage typical value: 25.5 V
• Varistor voltage tolerance range: 22.95 V to 28.05 V
• Surge current rating: 30 A
• Maximum AC voltage: 13 V
• Maximum DC voltage: 18 V
• Energy rating: 0.1 J
• Capacitance at 1 kHz: 225 pF
• Operating temperature range: -55°C to 125°C

Mechanical Parameters (Must Match):

• Package type: 0805 (2012 Metric)
• Mounting type: Surface Mount, MLCV
• Number of circuits: 1

Compliance & Quality Parameters (Must Match):

• Automotive grade classification
• AEC-Q200 qualification
• ROHS3 compliance
• MSL 1 rating
• REACH unaffected status

All three identified substitute parts meet these criteria without exception.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are functionally equivalent to the VCAS080518A400RP based on identical electrical and mechanical specifications. Selection among these parts should be based on the following factors:

Automotive Grade Compliance: The VCAS080518A400RP and VCAS080518A400DZ both carry explicit automotive grade designation with AEC-Q200 qualification. The VC080518A400DP and VC080518A400RP do not specify automotive grade or AEC-Q200 qualification in their documentation. For applications requiring automotive-grade components, VCAS080518A400DZ is the preferred substitute.

Product Availability: VCAS080518A400RP has the highest inventory level at 56,300 units. VCAS080518A400DZ has 4,632 units available. VC080518A400DP has 13,809 units. VC080518A400RP has the lowest inventory at 2,616 units.

Series Designation: VCAS080518A400RP and VCAS080518A400DZ belong to the FLEXITERM® series. VC080518A400DP and VC080518A400RP belong to the TransGuard® series. Both series are manufactured by KYOCERA AVX and meet all specified electrical parameters.

Packaging Format: All parts are supplied in Tape & Reel (TR) format suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can VC080518A400DP be used as a direct replacement for VCAS080518A400RP?

A: VC080518A400DP is electrically and mechanically equivalent to VCAS080518A400RP. All electrical parameters, package type, and mounting specifications are identical. However, VC080518A400DP does not specify automotive grade or AEC-Q200 qualification. For non-automotive applications, this part is a direct substitute. For automotive applications requiring AEC-Q200 compliance, VCAS080518A400DZ is the appropriate choice.

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

A: Both FLEXITERM® and TransGuard® series are manufactured by KYOCERA AVX and meet identical electrical specifications for the VCAS080518A400RP equivalent parts. The series designation reflects product line organization within the manufacturer's portfolio. All electrical and mechanical parameters are equivalent across both series for these specific part numbers.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All four parts (VCAS080518A400RP, VC080518A400DP, VC080518A400RP, and VCAS080518A400DZ) are ROHS3 compliant and REACH unaffected.

Q: What is the MSL rating for these parts?

A: All parts carry MSL 1 (Unlimited) rating, indicating unlimited shelf life under normal storage conditions without moisture bake-out requirements.

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

A: Yes. All parts use identical 0805 (2012 Metric) surface mount MLCV package specifications. They are compatible with standard pick-and-place assembly equipment and reflow soldering processes. No PCB layout or assembly process modifications are required when substituting between these parts.

Q: Which substitute part should be selected for automotive applications?

A: For automotive applications requiring AEC-Q200 qualification, VCAS080518A400DZ is the specified substitute. This part carries explicit automotive grade designation and AEC-Q200 qualification matching the original VCAS080518A400RP specification.

Q: Are there any temperature range differences between substitute parts?

A: No. All substitute parts operate across the identical temperature range of -55°C to 125°C (TA).

Q: What is the surge current rating for all these parts?

A: All parts are rated for 30 A surge current with 0.1 J energy dissipation capacity.
