Substitute Part Grouping Explanation

Substitution eligibility for the VCAS120614D300RZ is determined by strict equivalence across all electrical and mechanical parameters. The following criteria establish valid substitutes:

Electrical Parameters (Must Match Exactly):

• Varistor Voltage (Minimum, Typical, Maximum): 16.28 V / 18.5 V / 20.72 V
• Current - Surge: 150 A
• Maximum AC Volts: 10 V
• Maximum DC Volts: 14 V
• Energy: 0.4 J
• Capacitance @ 1 kHz: 1050 pF
• Number of Circuits: 1

Mechanical Parameters (Must Match Exactly):

• Package / Case: 1206 (3216 Metric)
• Mounting Type: Surface Mount, MLCV
• Operating Temperature Range: -55°C to 125°C

Compliance Parameters (Must Match Exactly):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected
• Series: TransGuard®

Variable Parameter (Packaging Format):

• Packaging format may differ (Tape & Reel vs. Cut Tape & Digi-Reel®) without affecting electrical or mechanical compatibility

All identified substitutes maintain identical electrical performance, thermal characteristics, and regulatory compliance. Packaging format differences reflect only the distribution method and do not impact component functionality or PCB assembly compatibility.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain full electrical and mechanical equivalence to the VCAS120614D300RZ. Selection between the main part and substitutes is based on packaging format availability and inventory requirements rather than performance differentiation.

VCAS120614D300RZ (Tape & Reel): Primary specification with 1515 units in stock. Suitable for high-volume production runs requiring standard reel packaging.

VC120614D300DP (Cut Tape & Digi-Reel®): Parametric equivalent with 2414 units in stock. Cut Tape format accommodates smaller order quantities and component-level procurement. Digi-Reel® packaging provides automated handling compatibility.

VC120614D300RP (Cut Tape & Digi-Reel®): Parametric equivalent with 4300 units in stock. Highest inventory availability. Cut Tape & Digi-Reel® format supports flexible procurement strategies.

VCAS120614D300DP (Tape & Reel): Parametric equivalent with 2622 units in stock. Maintains Tape & Reel packaging format identical to primary specification with alternative internal designation.

All parts carry Active product status, ROHS3 compliance, and REACH Unaffected designation. Component selection may be determined by supply chain logistics, assembly equipment compatibility with specific packaging formats, or project-specific inventory requirements. No electrical performance variation exists between any listed alternatives.

Frequently Asked Questions (FAQ)

Q: Can VC120614D300DP be used as a direct replacement for VCAS120614D300RZ?

A: Yes. VC120614D300DP is a parametric equivalent with identical electrical specifications (18.5 V typical varistor voltage, 150 A surge current, 0.4 J energy), mechanical configuration (1206 package, surface mount MLCV), and compliance status (ROHS3, REACH Unaffected). The only difference is packaging format: Cut Tape & Digi-Reel® versus Tape & Reel. This packaging difference does not affect component performance or PCB assembly compatibility.

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

A: Tape & Reel (TR) provides components on continuous carrier tape wound on reels, optimized for high-volume automated assembly. Cut Tape (CT) & Digi-Reel® provides components on cut tape segments with optional Digi-Reel® automated handling, suitable for smaller quantities and flexible procurement. Both formats contain identical components with no electrical or mechanical differences.

Q: Are all substitute parts from the same manufacturer?

A: Yes. All listed substitutes are manufactured by KYOCERA AVX, identical to the primary part. All components belong to the TransGuard® series.

Q: Do the substitute parts have the same operating temperature range?

A: Yes. All parts operate across -55°C to 125°C (TA), providing identical thermal performance and environmental suitability.

Q: Can I mix packaging formats in a single production run?

A: Yes. All listed parts are electrically and mechanically identical. Packaging format differences do not affect component functionality, PCB assembly compatibility, or circuit performance. Assembly equipment must support the specific packaging format being used.

Q: What is the capacitance specification for these varistors?

A: All parts specify 1050 pF capacitance measured at 1 kHz. This parameter is identical across all substitutes.

Q: Are all parts RoHS compliant?

A: Yes. All listed parts carry ROHS3 Compliant designation and REACH Unaffected status, meeting current environmental and regulatory requirements.

Q: Which substitute has the highest inventory availability?

A: VC120614D300RP maintains the highest inventory with 4300 units in stock, followed by VCAS120614D300DP with 2622 units, VC120614D300DP with 2414 units, and VCAS120614D300RZ with 1515 units.
