Substitute Part Grouping Explanation

Substitution of the BZX884-C7V5,315 is determined by strict equivalence across the following critical parameters:

Nominal Zener Voltage: 7.5 V (exact match required)
Maximum Power Dissipation: 250 mW (exact match required)
Package Type: SOD-882 / DFN1006-2 (exact match required)
Mounting Technology: Surface Mount (exact match required)
Automotive Grade: AEC-Q100 qualified (exact match required)
Operating Temperature Range: -65°C to 150°C (exact match required)

The BZX884-B7V5,315 qualifies as a parametric equivalent because it maintains identical electrical performance in voltage regulation, power handling, impedance characteristics, and reverse leakage specifications. The tolerance specification differs (±2% versus ±5%), representing a tighter tolerance band that is compatible with applications requiring the original part. Both parts share identical package geometry, thermal characteristics, and automotive qualification status.

Engineering Selection Recommendations

Both the BZX884-C7V5,315 and BZX884-B7V5,315 are Active products with full AEC-Q100 automotive qualification and ROHS3 compliance. Selection between these parts is based on tolerance requirements and inventory availability:

BZX884-C7V5,315 is selected when ±5% Zener voltage tolerance meets circuit design specifications and when supply from the current inventory of 1137 pieces is prioritized.

BZX884-B7V5,315 is selected when tighter ±2% Zener voltage tolerance is required for precision voltage regulation applications. This part carries higher inventory availability at 12021 pieces, supporting extended production runs and supply chain resilience.

Both parts maintain identical electrical performance in forward voltage drop, reverse leakage current, and impedance characteristics. Package geometry, thermal performance, and operating temperature range are identical. No design modifications are required when substituting between these parts; PCB layout and thermal management remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can BZX884-B7V5,315 be used as a direct replacement for BZX884-C7V5,315?

A: Yes. The BZX884-B7V5,315 is a direct parametric equivalent with identical electrical specifications for Zener voltage, power dissipation, impedance, and reverse leakage. The ±2% tolerance of the substitute part is tighter than the ±5% tolerance of the original part, making it compatible with all applications designed for the original component.

Q: What is the difference between the ±5% and ±2% tolerance specifications?

A: Tolerance specifies the allowable deviation of the Zener voltage from the nominal 7.5 V rating. The BZX884-C7V5,315 allows deviation between 7.125 V and 7.875 V. The BZX884-B7V5,315 allows deviation between 7.35 V and 7.65 V. Applications requiring tighter voltage regulation benefit from the ±2% specification.

Q: Are the package dimensions identical between these parts?

A: Yes. Both parts use the SOD-882 package type with DFN1006-2 supplier device package designation. PCB footprints, solder pad layouts, and component placement are identical.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both the BZX884-C7V5,315 and BZX884-B7V5,315 are Automotive grade components qualified to AEC-Q100 standards. Both are ROHS3 compliant and REACH unaffected.

Q: What is the operating temperature range for both parts?

A: Both parts operate across the identical temperature range of -65°C to 150°C, supporting automotive environmental conditions.

Q: Is there a difference in moisture sensitivity between these parts?

A: No. Both parts have Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no moisture-related handling restrictions.
