Key Parameters

Substitute Part Grouping Explanation

Substitution of the BZT52C4V7LP-TP is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Zener voltage (Vz) must be 4.7 V nominal
• Reverse leakage current must not exceed 3 µA @ 2 V
• Forward voltage (Vf) must not exceed 900 mV @ 10 mA
• Impedance (Zzt) must not exceed 80 Ohms
• Operating temperature range must encompass -65°C ~ 150°C

Mechanical Compatibility Criteria:

• Surface mount mounting type required
• Package must be SOD-882 or equivalent footprint
• RoHS3 compliance required
• MSL rating of 1 (Unlimited) required

The substitute part BZX884-C4V7,315 meets all electrical parameters and maintains mechanical compatibility while offering enhanced power rating (250 mW versus 100 mW) and improved tolerance (±5% versus ±6.38%). The substitute part is active in production status with automotive-grade qualification (AEC-Q100).

Parameter Comparison

Engineering Selection Recommendations

The BZX884-C4V7,315 is a direct electrical and mechanical substitute for the obsolete BZT52C4V7LP-TP. Both components share identical nominal zener voltage, impedance, reverse leakage current, and forward voltage characteristics. The substitute part maintains the same operating temperature range and package footprint (SOD-882).

The BZX884-C4V7,315 offers the following advantages:

• Active Production Status: The substitute is currently in active production, ensuring long-term availability and supply chain continuity.
• Improved Tolerance: ±5% tolerance versus ±6.38% provides tighter voltage regulation.
• Enhanced Power Rating: 250 mW maximum power dissipation versus 100 mW provides additional thermal margin in applications.
• Automotive Qualification: AEC-Q100 certification qualifies the substitute for automotive applications.
• Regulatory Compliance: Both ROHS3 compliant and REACH unaffected status confirmed.

Selection of the BZX884-C4V7,315 is appropriate for all applications previously using the BZT52C4V7LP-TP where the enhanced specifications do not create design conflicts.

Frequently Asked Questions (FAQ)

Q: Can the BZX884-C4V7,315 be used as a direct replacement for the BZT52C4V7LP-TP?

A: Yes. Both components share identical nominal zener voltage (4.7 V), impedance (80 Ohms maximum), reverse leakage current (3 µA @ 2 V), forward voltage (900 mV @ 10 mA), and operating temperature range (-65°C ~ 150°C). The package footprint (SOD-882) is identical, enabling direct PCB substitution.

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

A: The primary differences are product status, power rating, and tolerance. The BZT52C4V7LP-TP is obsolete with 100 mW power rating and ±6.38% tolerance. The BZX884-C4V7,315 is active in production with 250 mW power rating and ±5% tolerance. The substitute also includes AEC-Q100 automotive qualification.

Q: Does the higher power rating of the substitute create any compatibility issues?

A: No. The higher 250 mW power rating of the BZX884-C4V7,315 is a superset capability that does not create compatibility issues. Applications designed for 100 mW operation operate within the substitute's specifications.

Q: Are both parts RoHS compliant?

A: Yes. Both the BZT52C4V7LP-TP and BZX884-C4V7,315 are ROHS3 compliant. The substitute additionally confirms REACH unaffected status.

Q: What is the moisture sensitivity level for both parts?

A: Both components have MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Is the substitute suitable for automotive applications?

A: The BZX884-C4V7,315 carries AEC-Q100 automotive qualification. The original BZT52C4V7LP-TP does not specify automotive qualification. If automotive qualification is required, the substitute is appropriate.

Q: Are there any package differences between the two parts?

A: Both parts use the SOD-882 surface mount package. The BZX884-C4V7,315 is supplied in Tape & Reel (TR) packaging format, while the original part packaging format is not specified. The physical footprint and electrical interface are identical.
