Parameter Comparison

Engineering Selection Recommendations

The BZX884-C4V3,315 is the qualified substitute for the obsolete BZT52C4V3LP-TP based on the following engineering factors:

Electrical Equivalence: Both parts maintain identical nominal zener voltage (4.3 V), impedance (90 Ohms maximum), reverse leakage current (3 µA @ 1 V), and forward voltage characteristics (900 mV @ 10 mA). These parameters ensure functional interchangeability in voltage regulation and protection circuits.

Package and Mounting Compatibility: Both components utilize the SOD-882 surface mount package with identical footprint geometry, enabling direct board-level substitution without layout modifications.

Thermal and Environmental Compliance: Operating temperature ranges are identical (-65°C to 150°C), and both parts maintain unlimited moisture sensitivity rating (MSL 1). Both components comply with ROHS3 requirements and EAR99 export classification.

Product Status Advantage: The BZX884-C4V3,315 maintains active production status with NXP Semiconductors, ensuring long-term availability and supply chain continuity compared to the obsolete BZT52C4V3LP-TP.

Performance Enhancement: The substitute part provides 250 mW maximum power rating compared to 100 mW in the original part, with tighter voltage tolerance (±5% versus ±6.98%), offering improved performance margins in applications requiring higher power dissipation or tighter voltage regulation.

Frequently Asked Questions (FAQ)

Q: Can the BZX884-C4V3,315 be used as a direct replacement for the BZT52C4V3LP-TP?

A: Yes. Both parts share identical nominal zener voltage (4.3 V), impedance (90 Ohms), reverse leakage current (3 µA @ 1 V), forward voltage (900 mV @ 10 mA), operating temperature range (-65°C to 150°C), and SOD-882 package footprint. Direct board-level substitution is supported without circuit modifications.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer (Micro Commercial Co versus NXP Semiconductors), product status (obsolete versus active), maximum power rating (100 mW versus 250 mW), and voltage tolerance (±6.98% versus ±5%). The substitute part offers higher power capability and tighter voltage tolerance.

Q: Does the higher power rating of the BZX884-C4V3,315 affect circuit compatibility?

A: No. Higher maximum power rating does not negatively impact compatibility. The substitute part operates within identical voltage and current specifications, making it suitable for all applications designed for the original part. The increased power rating provides additional thermal margin in power-dissipation-limited applications.

Q: Are there any package or footprint differences?

A: No. Both parts use the SOD-882 surface mount package with identical footprint dimensions and pin configuration. No PCB layout changes are required for substitution.

Q: What is the significance of the tighter tolerance in the substitute part?

A: The BZX884-C4V3,315 provides ±5% voltage tolerance compared to ±6.98% in the original part. This tighter tolerance improves voltage regulation accuracy and reduces circuit design margins, benefiting applications requiring precise voltage reference or protection thresholds.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both parts comply with ROHS3 requirements and maintain EAR99 export classification. The substitute part is actively produced by NXP Semiconductors, ensuring ongoing compliance with current and future regulatory requirements.

Q: What is the inventory status for these parts?

A: The original BZT52C4V3LP-TP is obsolete with limited remaining inventory (1116 pieces). The BZX884-C4V3,315 is in active production with substantial inventory availability (17653 pieces), supporting immediate procurement and long-term supply continuity.
