Engineering Selection Recommendations

The BZX884S-C15-QYL is the primary substitute for the obsolete BZX884S-C15YL. Selection is based on the following factors:

Product Lifecycle Status: The substitute part maintains active product status with Nexperia USA Inc., ensuring long-term availability and supply chain continuity. The main part is classified as obsolete, making the substitute necessary for production continuity.

Compliance & Certification: Both parts are ROHS3 compliant and REACH unaffected. The substitute part carries AEC-Q100 automotive qualification, providing additional quality assurance for applications requiring automotive-grade components.

Electrical Equivalence: The substitute maintains identical power dissipation (365 mW), impedance (30 Ohms), reverse leakage current (50 nA @ 10.5 V), and forward voltage characteristics (900 mV @ 10 mA). The nominal Zener voltage difference of 0.3 V (14.7 V to 15 V) is within acceptable circuit design tolerances for standard voltage regulation applications.

Package & Mounting Compatibility: Both parts use identical SOD-882 packaging (DFN1006BD-2 supplier device package) with surface mount configuration, ensuring direct PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can BZX884S-C15-QYL directly replace BZX884S-C15YL in existing designs?

A: Yes. Both parts share identical package type (SOD-882), mounting configuration (surface mount), power rating (365 mW), impedance (30 Ohms), and thermal characteristics (150°C TJ). The 0.3 V nominal voltage difference (14.7 V to 15 V) is within standard circuit design tolerances for Zener diode applications.

Q: What is the significance of the tolerance difference between the two parts?

A: The main part has ±6.12% tolerance, while the substitute has ±2% tolerance. The substitute provides tighter voltage regulation with improved consistency. Both tolerances are acceptable for standard voltage regulation circuits, with the substitute offering superior performance.

Q: Are there any compliance or certification differences?

A: The substitute part (BZX884S-C15-QYL) carries AEC-Q100 automotive qualification in addition to ROHS3 compliance. Both parts are REACH unaffected. The substitute is suitable for automotive and industrial applications requiring higher quality assurance.
