Engineering Selection Recommendations

Both the BZX8450-C2V2R and BZX8450-C2V2VL are active products from Nexperia USA Inc. with identical electrical specifications and mechanical packaging. Selection between these parts is based on inventory availability and supply chain considerations rather than functional differences.

The BZX8450-C2V2R carries 3,070 pieces in current stock inventory. The BZX8450-C2V2VL carries 10,449 pieces in current stock inventory, providing greater availability for high-volume applications.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for commercial and industrial applications. Moisture sensitivity level MSL 1 (Unlimited) indicates no special storage or handling requirements.

Frequently Asked Questions (FAQ)

Q: Can BZX8450-C2V2VL be used as a direct replacement for BZX8450-C2V2R?

A: Yes. Both parts are parametric equivalents with identical Zener voltage (2.2 V), power rating (250 mW), impedance (100 Ohms), reverse leakage current (4 µA @ 1 V), forward voltage (900 mV @ 10 mA), and operating temperature (150°C). Package configuration, mounting type, and compliance certifications are identical.

Q: Are there any differences in the TO-236AB package between these parts?

A: No. Both parts use the TO-236AB package configuration, also designated as SC-59 or SOT-23-3. Pin configuration, lead spacing, and mechanical dimensions are identical.

Q: What is the primary reason to select one part over the other?

A: Inventory availability is the primary selection criterion. The BZX8450-C2V2VL has higher stock levels (10,449 pieces) compared to the BZX8450-C2V2R (3,070 pieces), making it preferable for applications requiring immediate delivery or large-quantity orders.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected. Moisture sensitivity level is MSL 1 (Unlimited) for both, requiring no special environmental controls during storage or assembly.

Q: Is the ±5% tolerance specification identical for both parts?

A: Yes. Both the BZX8450-C2V2R and BZX8450-C2V2VL maintain ±5% tolerance on the 2.2 V nominal Zener voltage specification.
