BZX884S-C75YL Equivalent & Substitute Parts

Part Overview

The BZX884S-C75YL is a surface mount Zener diode manufactured by Nexperia USA Inc., rated at 74.5 V nominal with 365 mW maximum power dissipation. This component is classified as obsolete, indicating discontinuation from active production. The part is packaged in SOD-882 (DFN1006BD-2) configuration and complies with RoHS3 and REACH regulations. Due to its obsolete status, equivalent substitute parts with active production status are necessary for new designs and ongoing procurement requirements.

Substitute Part Grouping Explanation

Substitution of the BZX884S-C75YL is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

Zener voltage rating within acceptable tolerance band
Maximum power dissipation capacity
Reverse leakage current characteristics
Forward voltage characteristics
Operating temperature range

Mechanical Compatibility Criteria:

Package type: SOD-882 (DFN1006BD-2)
Surface mount configuration
Mounting footprint compatibility

The substitute part BZX884S-C75-QYL meets these criteria with a nominal Zener voltage of 75 V (within the tolerance specification of the original part when accounting for the ±6.04% tolerance band of the main part), identical maximum power rating of 365 mW, matching impedance characteristics, and identical package configuration. Both parts share the same reverse leakage current specification, forward voltage characteristics, and operating temperature maximum.

Engineering Selection Recommendations

The BZX884S-C75-QYL is the direct substitute for the obsolete BZX884S-C75YL. Selection of this substitute is based on the following engineering factors:

Product Status: The substitute part maintains active production status, ensuring long-term availability and supply chain continuity. The main part is obsolete and subject to discontinuation of manufacturing and support.

Regulatory Compliance: Both parts maintain identical RoHS3 compliance and REACH unaffected status, ensuring regulatory requirements are satisfied in applications requiring these certifications.

Automotive Qualification: The substitute part carries AEC-Q100 automotive qualification, providing additional quality assurance for applications requiring automotive-grade components.

Electrical Performance: The substitute part exhibits tighter tolerance (±2% versus ±6.04%), resulting in improved voltage regulation accuracy. The nominal voltage difference of 0.5 V (75 V versus 74.5 V) falls within the tolerance band of the original part and does not constitute a functional limitation for Zener diode applications.

Mechanical Compatibility: Identical package configuration (SOD-882/DFN1006BD-2) ensures direct footprint compatibility without PCB redesign.

Frequently Asked Questions (FAQ)

Q: Can BZX884S-C75-QYL be used as a direct replacement for BZX884S-C75YL?

A: Yes. Both parts share identical package configuration (SOD-882), maximum power rating (365 mW), impedance characteristics (255 Ohms maximum), reverse leakage current (50 nA @ 52.5 V), and forward voltage characteristics (900 mV @ 10 mA). The nominal voltage difference of 0.5 V is within the tolerance specification of the original part.

Q: What is the primary advantage of selecting BZX884S-C75-QYL?

A: The substitute part is in active production status, whereas the original part is obsolete. This ensures reliable procurement, extended availability, and manufacturer support. Additionally, the substitute offers tighter voltage tolerance (±2% versus ±6.04%), improving regulation accuracy.

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

A: No. Both parts use SOD-882 package configuration with DFN1006BD-2 supplier device package designation. The substitute is available in Tape & Reel (TR) packaging, which is standard for production quantities.

Q: Does the substitute part meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected. The substitute additionally carries AEC-Q100 automotive qualification, providing enhanced quality assurance for automotive applications.

Q: What is the significance of the ±2% tolerance on the substitute part?

A: The tighter tolerance specification on BZX884S-C75-QYL (±2% versus ±6.04%) results in more precise Zener voltage regulation. This provides improved circuit performance and reduced voltage variation across production batches.

Q: Are the electrical characteristics identical between the two parts?

A: The electrical characteristics are functionally equivalent. Both parts share identical maximum power dissipation (365 mW), impedance (255 Ohms), reverse leakage current (50 nA @ 52.5 V), forward voltage (900 mV @ 10 mA), and operating temperature maximum (150°C).
