Substitute Part Grouping Explanation

Substitute parts for the VCAS080518A400DP are identified based on strict electrical and mechanical parameter matching within the Transient Voltage Suppressors (TVS) category. The substitution logic is based on the following criteria:

Electrical Parameters (Must Match):

• Varistor Voltage (Typical): 25.5 V
• Varistor Voltage Range: 22.95 V (Min) to 28.05 V (Max)
• Current - Surge: 30 A
• Maximum AC Volts: 13 V
• Maximum DC Volts: 18 V
• Energy: 0.1 J
• Capacitance @ 1 kHz: 225 pF
• Operating Temperature Range: -55°C to 125°C

Mechanical Parameters (Must Match):

• Package / Case: 0805 (2012 Metric)
• Mounting Type: Surface Mount, MLCV
• Number of Circuits: 1

Compliance & Certification (Must Match):

• Manufacturer: KYOCERA AVX
• Category: Transient Voltage Suppressors (TVS)
• Grade: Automotive
• Qualification: AEC-Q200
• RoHS Status: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)
• REACH Status: REACH Unaffected

All identified substitute parts maintain identical electrical performance, mechanical compatibility, and automotive-grade compliance with the main part.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain full electrical and mechanical compatibility with the VCAS080518A400DP. Selection among these parts is based on availability and packaging preference:

VCAS080518A400DP (Main Part): FLEXITERM® series, Automotive grade with AEC-Q200 qualification. Current inventory: 1045 pcs.

VC080518A400DP: TransGuard® series equivalent with identical electrical specifications. Highest inventory availability at 13,809 pcs. Suitable for direct substitution where series designation is not a constraint.

VC080518A400RP: TransGuard® series equivalent with identical electrical specifications. Inventory: 2,616 pcs. Suitable for direct substitution where series designation is not a constraint.

VCAS080518A400DZ: FLEXITERM® series, matching the main part's series designation. Automotive grade with AEC-Q200 qualification. Inventory: 4,632 pcs. Recommended when series continuity is required.

All parts comply with ROHS3, maintain MSL 1 (Unlimited) rating, and are REACH Unaffected. Selection should prioritize inventory availability and application-specific series requirements.

Frequently Asked Questions (FAQ)

Q: Can VC080518A400DP and VC080518A400RP be used interchangeably with VCAS080518A400DP?

A: Yes. All three parts share identical electrical parameters (25.5 V typical varistor voltage, 30 A surge current, 0.1 J energy), mechanical specifications (0805 package, surface mount MLCV), and compliance certifications (ROHS3, REACH Unaffected). The primary difference is the series designation (TransGuard® versus FLEXITERM®). Substitution is valid when series continuity is not a design requirement.

Q: What is the difference between VCAS080518A400DP and VCAS080518A400DZ?

A: Both parts belong to the FLEXITERM® series and share identical electrical and mechanical specifications. The difference lies in packaging designation (DP versus DZ suffix). Both maintain Automotive grade and AEC-Q200 qualification. Selection between these parts depends on packaging preference and inventory availability.

Q: Are all substitute parts automotive-qualified?

A: VCAS080518A400DP and VCAS080518A400DZ carry explicit Automotive grade designation with AEC-Q200 qualification. VC080518A400DP and VC080518A400RP do not list explicit Automotive grade or AEC-Q200 qualification in their specifications. For applications requiring automotive compliance, VCAS080518A400DP or VCAS080518A400DZ are the appropriate selections.

Q: Can these varistors be used in applications exceeding 18 V DC or 13 V AC?

A: No. The maximum DC voltage rating is 18 V and maximum AC voltage rating is 13 V. Operation beyond these limits violates the component specifications and may result in component failure or degraded performance.

Q: What is the significance of the 225 pF capacitance specification?

A: The 225 pF capacitance measured at 1 kHz is an inherent characteristic of the varistor structure. This parameter is identical across all substitute parts and must be considered in circuit design, particularly in high-frequency applications where capacitive effects may influence circuit behavior.

Q: Are all parts available in Tape & Reel packaging?

A: Yes. All listed parts are supplied in Tape & Reel (TR) packaging format, suitable for automated assembly processes.

Q: What does MSL 1 (Unlimited) mean?

A: MSL (Moisture Sensitivity Level) 1 indicates the lowest moisture sensitivity classification. The "Unlimited" designation means these components can be stored indefinitely without special moisture control measures, simplifying inventory management and reducing handling requirements.
