This part maintains complete electrical and mechanical compatibility while offering improved tolerance performance (±2% versus ±6.67%). The BZX884S-C30-QYL carries AEC-Q100 automotive qualification and is currently in active production with substantial inventory availability (9421 pieces).

BZX884S-B30-QYL is a parametric equivalent offering identical electrical specifications and mechanical packaging. This part also carries AEC-Q100 automotive qualification and is in active production with higher inventory availability (10103 pieces). Selection between BZX884S-C30-QYL and BZX884S-B30-QYL depends on application-specific requirements and design constraints not specified in the electrical parameters.

Both substitute parts are ROHS3 compliant and REACH unaffected, maintaining regulatory compliance with the original component. The transition from obsolete to active production status ensures long-term supply chain stability and continued technical support.

Frequently Asked Questions (FAQ)

Q: Can BZX884S-C30-QYL and BZX884S-B30-QYL be used interchangeably with BZX884S-C30YL?

A: Both substitute parts maintain identical electrical specifications (30 V nominal Zener voltage, 365 mW maximum power, 80 Ohms maximum impedance) and mechanical packaging (SOD-882, surface mount, DFN1006BD-2). Direct substitution is supported by parameter equivalence.

Q: What is the difference between the tolerance specifications?

A: The BZX884S-C30YL specifies ±6.67% tolerance, while both substitute parts (BZX884S-C30-QYL and BZX884S-B30-QYL) specify ±2% tolerance. The substitute parts provide tighter voltage regulation, which may improve circuit performance in applications sensitive to Zener voltage variation.

Q: Are the substitute parts suitable for automotive applications?

A: Both BZX884S-C30-QYL and BZX884S-B30-QYL carry automotive-grade classification and AEC-Q100 qualification. These certifications indicate suitability for automotive applications. The original BZX884S-C30YL does not specify automotive qualification.

Q: What is the significance of the product status change from Obsolete to Active?

A: The transition from obsolete to active status indicates that substitute parts are in current production with ongoing manufacturer support. This ensures continued availability, technical documentation, and supply chain reliability for future procurement.

Q: Are there any packaging differences between the main part and substitutes?

A: All three parts utilize identical packaging: SOD-882 case with DFN1006BD-2 supplier device package. The main part is supplied in standard packaging, while substitute parts are supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly.

Q: Do the substitute parts meet the same regulatory compliance standards?

A: All three parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity level (MSL 1 - Unlimited). Regulatory compliance is maintained across the substitution.
