Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

BZX884S-B10-QYL and BZX884S-C10-QYL are the preferred substitutes for the BZX884S-C10YL. Both parts are classified as Active products, ensuring long-term availability and manufacturing support. Both parts feature improved voltage tolerance (±2% versus ±6%), providing tighter voltage regulation characteristics. Both parts carry AEC-Q100 automotive qualification and are supplied in Tape & Reel packaging, supporting high-volume production environments.

Secondary Substitutes (Obsolete Product Status):

BZX8850S-C10YL is functionally equivalent but classified as Obsolete. This part exhibits lower reverse leakage current (100 nA @ 7.6 V versus 200 nA @ 7 V) and ±5% voltage tolerance. Use of this part is restricted to applications where existing inventory is available or where the improved leakage characteristics provide specific design advantages. Long-term procurement of this part is not supported.

Packaging Consideration:

The original BZX884S-C10YL is supplied without specified packaging designation. All substitute parts are available in Tape & Reel (TR) packaging, which is standard for surface mount component procurement and automated assembly processes.

Compliance Status:

All substitute parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment with the original component specification.

Frequently Asked Questions (FAQ)

Q: Can BZX884S-B10-QYL and BZX884S-C10-QYL be used interchangeably with BZX884S-C10YL?

A: Yes. Both parts meet all critical electrical and mechanical parameters. The primary difference is improved voltage tolerance (±2% versus ±6%), which provides superior voltage regulation. Both parts are Active products with full manufacturing support.

Q: What is the significance of the tolerance difference between ±6% and ±2%?

A: Tolerance specifies the allowable deviation of the Zener voltage from the nominal 10 V rating. The ±6% tolerance of the original part allows voltage variation between 9.4 V and 10.6 V. The ±2% tolerance of the substitute parts restricts variation to 9.8 V and 10.2 V, providing tighter voltage regulation. Applications requiring precise voltage reference characteristics benefit from the improved tolerance.

Q: Why is BZX8850S-C10YL classified as a secondary substitute despite being functionally equivalent?

A: BZX8850S-C10YL is classified as Obsolete, indicating discontinued manufacturing and limited long-term availability. While the part meets electrical specifications, procurement of new inventory is not supported. Use of this part is restricted to applications with existing stock or where the lower reverse leakage current (100 nA) provides specific design advantages.

Q: Are all substitute parts available in the same package configuration?

A: All substitute parts use the SOD-882 package (DFN1006BD-2 supplier device package), ensuring mechanical and thermal compatibility. The original part does not specify a packaging type, while all substitutes are supplied in Tape & Reel (TR) format, which is standard for automated surface mount assembly.

Q: Do the substitute parts carry automotive qualification?

A: BZX884S-B10-QYL and BZX884S-C10-QYL carry AEC-Q100 automotive qualification. BZX8850S-C10YL does not specify automotive qualification. Applications requiring automotive-grade components should use BZX884S-B10-QYL or BZX884S-C10-QYL.

Q: What is the impact of reverse leakage current variation between 100 nA and 200 nA?

A: Reverse leakage current affects standby power consumption and circuit performance at reverse bias conditions. The BZX8850S-C10YL exhibits lower reverse leakage (100 nA @ 7.6 V), which may provide advantages in low-power or precision applications. The BZX884S-C10YL and its primary substitutes specify 200 nA @ 7 V. Selection depends on specific circuit requirements.

Q: Can these parts be used in new designs, or are they restricted to replacement applications?

A: BZX884S-B10-QYL and BZX884S-C10-QYL are Active products and are suitable for both new designs and replacement applications. BZX8850S-C10YL and the original BZX884S-C10YL are Obsolete and should be restricted to replacement scenarios where existing inventory is available.
