VCAS120618D400TP Equivalent & Substitute Parts

Part Overview

The VCAS120618D400TP is a 25.5 V 150 A transient voltage suppressor (TVS) varistor manufactured by KYOCERA AVX in the FLEXITERM® series. This surface mount device in 1206 (3216 metric) package is actively produced and AEC-Q200 qualified for automotive applications. Substitute parts are necessary when the primary packaging format (Tape & Reel) is unavailable or when alternative tape/reel delivery methods better suit manufacturing logistics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the VCAS120618D400TP are determined by strict parametric equivalence across electrical and mechanical specifications. All substitute parts maintain identical varistor voltage characteristics (25.5 V typical, 22.95 V minimum, 28.05 V maximum), surge current handling (150 A), maximum voltage ratings, energy absorption (0.4 J), capacitance (900 pF @ 1 kHz), and operating temperature range (-55°C to 125°C). All substitute parts use the same 1206 surface mount MLCV package.

Substitutes are differentiated only by delivery packaging format: Tape & Reel (TR) versus Cut Tape (CT) & Digi-Reel®. The electrical and thermal performance, compliance status (ROHS3, REACH Unaffected, EAR99), and automotive qualification (AEC-Q200) remain constant across all equivalent variants.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active products from KYOCERA AVX with AEC-Q200 automotive qualification and ROHS3 compliance. Selection between the primary part (VCAS120618D400TP) and substitutes depends on delivery packaging requirements:

• VCAS120618D400TP: Tape & Reel (TR) delivery with 780 units in stock. Select for standard automated pick-and-place assembly lines.
• VC120618D400DP: Cut Tape (CT) & Digi-Reel® delivery with 16066 units in stock. Select when Digi-Reel® automated handling is integrated into production.
• VCAS120618D400DP: Tape & Reel (TR) delivery with 1113 units in stock. Alternative TR option with lower inventory.
• VCAS120618D400DZ: Tape & Reel (TR) delivery with 4696 units in stock. FLEXITERM® series variant in TR format.
• VCAS120618D400RP: Cut Tape (CT) & Digi-Reel® delivery with 4529 units in stock. Alternative CT/Digi-Reel option.

All parts meet identical electrical specifications and thermal performance requirements for transient voltage suppression in automotive circuits with DC supply up to 18 V.

Frequently Asked Questions (FAQ)

Q: Are all substitute parts electrically identical to VCAS120618D400TP? A: Yes. All substitute parts maintain the same varistor voltage (25.5 V typical, 22.95–28.05 V range), surge current capability (150 A), maximum voltage ratings, energy absorption (0.4 J), and operating temperature range (-55°C to 125°C).

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® packaging? A: Tape & Reel (TR) delivers components on continuous tape on plastic reels, suitable for standard pick-and-place equipment. Cut Tape (CT) & Digi-Reel® provides components cut from tape, compatible with Digi-Reel® automated handling systems. Both are surface mount compatible in the 1206 package.

Q: Can I substitute between packaging formats within the same production run? A: All parts maintain identical mechanical fit (1206 package, surface mount MLCV), electrical performance, and compliance certifications. Selection should be based on equipment compatibility and supply chain requirements.

Q: Are all substitute parts AEC-Q200 qualified? A: All parts listed carry active product status. Refer to individual datasheets for specific qualification badges, though all meet automotive-grade requirements with -55°C to 125°C operating temperature range.

Q: What is the inventory status for urgent requirements? A: VC120618D400DP carries the highest inventory (16066 units), followed by VCAS120618D400DZ (4696 units) and VCAS120618D400RP (4529 units). Primary part VCAS120618D400TP has 780 units available.
