Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VCAS120618E380RP is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Varistor Voltage (Typical): 25.5 V
• Varistor Voltage Range: 22.95 V (Min) to 28.05 V (Max)
• Current - Surge: 200 A
• Energy Rating: 0.5 J
• Maximum DC Volts: 18 V
• Maximum AC Volts: 13 V
• Capacitance @ 1 kHz: 930 pF

Mechanical & Environmental Parameters:

• Package / Case: 1206 (3216 Metric)
• Mounting Type: Surface Mount, MLCV
• Number of Circuits: 1
• Operating Temperature Range: -55°C ~ 125°C (TA)

Compliance & Quality Parameters:

• Grade: Automotive
• Qualification: AEC-Q200
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• Series: FLEXITERM®

The substitute part VCAS120618E380DZ meets all specified electrical, mechanical, and compliance requirements and is therefore classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the VCAS120618E380RP and VCAS120618E380DZ are active production components manufactured by KYOCERA AVX within the FLEXITERM® series. Selection between these parts is based on inventory availability and supply chain requirements rather than electrical or mechanical performance differences.

VCAS120618E380RP is suitable for applications where the specific part number designation is required or preferred, with current inventory of 707 units.

VCAS120618E380DZ is suitable for applications where supply chain flexibility is prioritized, with higher current inventory of 4,980 units available.

Both components satisfy automotive-grade requirements with AEC-Q200 qualification, ROHS3 compliance, and unlimited moisture sensitivity level (MSL 1). Both operate across the full temperature range of -55°C to 125°C and deliver identical electrical performance in transient voltage suppression applications.

Frequently Asked Questions (FAQ)

Q: Can VCAS120618E380DZ be used as a direct replacement for VCAS120618E380RP?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, mechanical dimensions, and compliance certifications. Direct substitution is supported without circuit redesign.

Q: Are there differences in the package or mounting requirements?

A: No. Both components use the 1206 (3216 Metric) surface mount package with MLCV mounting type. PCB footprints and reflow profiles are identical.

Q: What is the difference between the two part numbers?

A: The part numbers differ in their suffix designation (RP versus DZ), which typically indicates different packaging or distribution channels from KYOCERA AVX. All electrical and mechanical parameters remain identical.

Q: Are both parts automotive-qualified?

A: Yes. Both VCAS120618E380RP and VCAS120618E380DZ carry automotive-grade classification with AEC-Q200 qualification, suitable for automotive transient voltage suppression applications.

Q: What is the varistor voltage specification for these parts?

A: The typical varistor voltage is 25.5 V, with a specified range of 22.95 V (minimum) to 28.05 V (maximum). Both parts meet this specification identically.

Q: Are these parts RoHS compliant?

A: Yes. Both components are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What surge current rating do these varistors support?

A: Both parts are rated for 200 A surge current with 0.5 J energy absorption capacity in a single-circuit configuration.
