VC120618D400TP Equivalent & Substitute Parts Reference

Part Overview

The VC120618D400TP is a Transient Voltage Suppressor (TVS) varistor manufactured by KYOCERA AVX in the TransGuard® series. This surface mount component, housed in a 1206 (3216 Metric) package, is designed to protect circuits against transient voltage surges with a nominal varistor voltage of 25.5 V and surge current handling capability of 150 A. The part maintains Active product status and is ROHS3 compliant. Alternative part numbers are necessary to accommodate different packaging formats (Tape & Reel vs. Cut Tape), inventory availability, or automotive-grade requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the VC120618D400TP is determined by strict equivalence in the following electrical and mechanical parameters:

• Varistor Voltage (Typical): 25.5 V
• Varistor Voltage Range: 22.95 V (Min) to 28.05 V (Max)
• Current - Surge: 150 A
• Maximum DC / AC Volts: 18 V DC, 13 V AC
• Energy Rating: 0.4 J
• Capacitance: 900 pF @ 1 kHz
• Operating Temperature Range: -55°C to 125°C
• Package / Case: 1206 (3216 Metric)
• Mounting Type: Surface Mount, MLCV
• Moisture Sensitivity Level: 1 (Unlimited)
• Regulatory Compliance: ROHS3 Compliant

All listed substitute parts maintain identical electrical performance specifications and mechanical compatibility. Differences exist only in packaging format (Tape & Reel vs. Cut Tape & Digi-Reel®) and product series designation, which do not affect circuit functionality or board-level integration.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts are Active products manufactured by KYOCERA AVX with ROHS3 Compliant status and identical MSL ratings. Selection between the main part (VC120618D400TP) and substitute parts should be based on procurement requirements and packaging format availability:

• VC120618D400DP and VCAS120618D400RP are available in Cut Tape (CT) & Digi-Reel® packaging, providing higher current inventory levels (16066 and 4529 units respectively) for high-volume applications.
• VCAS120618D400DP and VCAS120618D400DZ are supplied in Tape & Reel (TR) format. The VCAS120618D400DZ variant is qualified to AEC-Q200 automotive standards and is designated as FLEXITERM® series, suitable for automotive circuit protection applications.
• VC120618D400TP (Tape & Reel) remains the primary specification for standard industrial applications.

All parts share identical electrical performance, regulatory compliance, and moisture sensitivity characteristics. Packaging format selection should align with assembly equipment capabilities and procurement volumes.

Frequently Asked Questions (FAQ)

Q: Can I substitute any listed part number for another in my circuit design? A: Yes. All parts listed maintain identical electrical specifications for varistor voltage (25.5 V), surge current (150 A), energy rating (0.4 J), and operating temperature range (-55°C to 125°C). Substitution is electrically transparent at the circuit level.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® packaging? A: These are distribution formats only. Tape & Reel packaging supplies components in continuous reels for automated assembly lines, while Cut Tape & Digi-Reel® provide components in cut tape segments with reel options. The component itself is functionally identical.

Q: Is VCAS120618D400DZ suitable for automotive applications? A: Yes. The VCAS120618D400DZ is qualified to AEC-Q200 automotive standards and designated as FLEXITERM® series. It maintains all electrical equivalence to other parts while meeting automotive-grade reliability requirements.

Q: How do I determine which part number to order based on manufacturing equipment? A: Select based on your assembly equipment compatibility: use Tape & Reel (TR) parts for automatic pick-and-place machines designed for reel feeding (VC120618D400TP, VCAS120618D400DP, VCAS120618D400DZ), or Cut Tape (CT) & Digi-Reel® parts (VC120618D400DP, VCAS120618D400RP) for equipment requiring cut tape or bulk component feeding.

Q: Are all parts ROHS3 compliant and MSL rated? A: Yes. All substitute parts are ROHS3 Compliant with MSL 1 (Unlimited moisture sensitivity level), indicating no special moisture protection handling is required during storage or transport.

Q: What is the capacitance rating for these parts? A: All parts have 900 pF capacitance measured at 1 kHz. This parameter is consistent across all equivalent variants.
