Substitute Part Grouping Explanation

Substitution for the VCAS040214X300WP is determined by strict equivalence across the following critical parameters:

• Varistor voltage range (Min: 16.28 V, Typ: 18.5 V, Max: 20.72 V)
• Surge current rating (20 A)
• Maximum AC and DC voltage ratings (10 V AC, 14 V DC)
• Energy absorption capacity (0.05 J)
• Package and mounting configuration (0402 MLCV surface mount)
• Operating temperature range (-55°C to 125°C)
• Compliance certifications (RoHS3, REACH unaffected)

The identified substitute maintains identical electrical specifications and physical packaging, ensuring direct compatibility in circuit applications without design modification.

Frequently Asked Questions (FAQ)

Q: Can VC040214X300WP be used as a direct replacement for VCAS040214X300WP?

A: Yes. Both parts are electrically and mechanically identical with matching varistor voltage ratings (18.5 V typical), surge current capacity (20 A), package configuration (0402 MLCV), and operating temperature range (-55°C to 125°C). No circuit redesign is necessary.

Q: Are there any compliance differences between these substitute parts?

A: No. Both parts maintain identical RoHS3 compliance status and REACH unaffected designation. Moisture sensitivity level is 1 (Unlimited) for both variants.

Q: What determines substitution eligibility for this TVS varistor?

A: Substitution is based on matching varistor voltage range (16.28 V to 20.72 V), surge current rating (20 A), maximum voltage ratings (10 V AC, 14 V DC), energy absorption (0.05 J), capacitance (85 pF @ 1 kHz), package type (0402 MLCV surface mount), and operating temperature range (-55°C to 125°C).

Q: Is the 0402 package dimension critical for substitution?

A: Yes. The 0402 (1005 Metric) surface mount package is a critical parameter. Both substitute parts use identical MLCV mounting configuration, ensuring compatibility with existing PCB layouts and assembly processes.

Q: What is the significance of the TransGuard® series designation?

A: TransGuard® is the KYOCERA AVX product series identifier for these varistors. Both the main part and substitute maintain this series designation, confirming they are part of the same product family with consistent design and performance characteristics.
