Substitute Part Grouping Explanation

Substitution eligibility is determined by strict parametric equivalency across the following critical parameters: varistor voltage range (45.9 V - 56.1 V typical 51 V), surge current capacity (180 A), energy rating (0.8 J), maximum AC/DC voltage ratings, capacitance at 1 kHz (600 pF), operating temperature range (-55°C to 125°C), and physical package specification (Surface Mount MLCV 1206 / 3216 Metric). All substitute parts identified maintain identical electrical characteristics, automotive-grade classification, AEC-Q200 qualification status, and ROHS3 compliance. Substitution is valid only when all specified parameters remain constant.

Engineering Selection Recommendations

All three parts (VCAS120642L800RP, VC120642L800DP, and VCAS120642L800TP) are manufactured by KYOCERA AVX and maintain identical electrical and mechanical parameters. Selection criteria should be based on product status and compliance requirements:

VCAS120642L800RP and VCAS120642L800TP are explicitly qualified as automotive-grade components with AEC-Q200 certification. These parts are suitable for automotive and safety-critical applications requiring formal qualification documentation.

VC120642L800DP maintains identical electrical specifications and packaging but does not declare explicit automotive grade or AEC-Q200 qualification in the provided data. Selection of this part requires verification of application requirements regarding automotive qualification necessity.

All three parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), confirming compatibility with modern manufacturing and storage environments.

Frequently Asked Questions (FAQ)

Q: Can VC120642L800DP be substituted for VCAS120642L800RP in automotive applications? A: Both parts maintain identical electrical and mechanical specifications including varistor voltage (51 V), surge current (180 A), energy rating (0.8 J), and package type (1206). However, VC120642L800DP does not declare explicit automotive grade or AEC-Q200 qualification. Substitution validity depends on application qualification requirements. If AEC-Q200 certification is required for your application, select VCAS120642L800RP or VCAS120642L800TP.

Q: Are all three parts physically identical? A: Yes. All three parts use the Surface Mount MLCV 1206 (3216 Metric) package with identical dimensions, allowing direct board-level substitution without PCB modifications.

Q: What is the significance of the packaging designations (RP, DP, TP) in these part numbers? A: The packaging designations indicate different tape and reel configurations. RP, DP, and TP represent different supplier or packaging variants. All three are supplied in Tape & Reel format with identical component specifications.

Q: Can these parts be used interchangeably in production? A: All three parts are declared as Active product status with identical electrical performance. Interchangeability at the component level is confirmed. Production substitution requires documentation and qualification review if automotive-grade or AEC-Q200 status is a design specification.

Q: What is the moisture sensitivity level significance? A: Moisture Sensitivity Level 1 (Unlimited) indicates the component has no moisture-related handling or storage restrictions. All three parts support unlimited shelf life under standard warehouse conditions without desiccant or controlled humidity requirements.
