Substitute Part Grouping Explanation

Substitution of the VCAS120642L800TP is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part VC120642L800DP is classified as a parametric equivalent based on the following criteria:

Substitution-Determining Parameters:

• Varistor voltage rating: 51 V (typical), with identical minimum and maximum tolerances (45.9 V - 56.1 V)
• Surge current capacity: 180 A
• Energy absorption: 0.8 J
• Maximum AC and DC voltage ratings: 32 V AC / 42 V DC
• Capacitance specification: 600 pF @ 1 kHz
• Operating temperature range: -55°C to 125°C
• Package designation: 1206 (3216 Metric) surface mount
• Mounting technology: MLCV surface mount
• Single circuit configuration

Both parts are manufactured by KYOCERA AVX, maintain Active product status, carry AEC-Q200 automotive qualification, and comply with ROHS3 and REACH requirements. The substitute part is functionally and mechanically interchangeable for all applications requiring the specified electrical performance envelope.

Frequently Asked Questions (FAQ)

Q: Can VC120642L800DP be used as a direct replacement for VCAS120642L800TP?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, including 51 V varistor voltage, 180 A surge current, 0.8 J energy absorption, and operating temperature range. They share the same 1206 (3216 Metric) surface mount package and MLCV mounting technology. No circuit modifications are required.

Q: Are there any differences in automotive qualification between these parts?

A: No. Both VCAS120642L800TP and VC120642L800DP carry AEC-Q200 qualification and are suitable for automotive applications. Compliance status is identical.

Q: What is the significance of the part number suffix (TP vs. DP)?

A: The suffix indicates packaging or distribution channel designation within KYOCERA AVX's product line. Both suffixes represent the same electrical component with identical performance specifications.

Q: Do these parts require different PCB footprints?

A: No. Both parts use the 1206 (3216 Metric) package with identical surface mount MLCV mounting technology. PCB footprints and assembly processes are identical.

Q: Are there any moisture sensitivity or storage requirement differences?

A: No. Both parts carry MSL Level 1 (Unlimited) rating, indicating no special moisture control measures are required during storage, handling, or assembly.

Q: Can these parts be mixed in the same production batch?

A: Yes. Since both parts are parametric equivalents with identical electrical and mechanical specifications, they can be used interchangeably in the same design and production environment without functional or reliability impact.

Q: What is the basis for substitution eligibility?

A: Substitution is based on strict equivalence of all critical parameters: varistor voltage rating (45.9 V - 56.1 V), surge current (180 A), energy absorption (0.8 J), maximum voltage ratings (32 V AC / 42 V DC), capacitance (600 pF @ 1 kHz), operating temperature range (-55°C to 125°C), package type (1206 / 3216 Metric), and mounting technology (surface mount MLCV). Both parts are manufactured by the same supplier and maintain identical compliance certifications.
