BZT52C2V4LP-TP Equivalent & Substitute Parts

Part Overview

The BZT52C2V4LP-TP is a Zener diode rated at 2.4 V nominal voltage with 100 mW maximum power dissipation in a surface mount SOD-882 package. Manufactured by Micro Commercial Co, this component is classified as obsolete. Due to its obsolete status and limited availability relative to active alternatives, identifying equivalent substitute parts is necessary for ongoing design support and production continuity. Substitute parts must maintain electrical equivalence across voltage regulation, power handling, and thermal operating range while accommodating package and certification requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BZT52C2V4LP-TP is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Matching Parameters:

• Zener voltage nominal value: 2.4 V
• Impedance (Max): 100 Ohms
• Current - Reverse Leakage @ Vr: 50 µA @ 1 V
• Voltage - Forward (Vf) (Max) @ If: 900 mV @ 10 mA
• Operating Temperature Range: -65°C to 150°C
• Mounting Type: Surface Mount
• Package / Case: SOD-882
• RoHS Compliance: ROHS3 Compliant

The substitute part BZX884-C2V4,315 meets all critical electrical parameters and maintains SOD-882 package compatibility. While the substitute exhibits improved tolerance (±5% versus ±8.33%) and higher power rating (250 mW versus 100 mW), these represent enhanced performance characteristics that do not preclude substitution. The substitute part is classified as active with automotive-grade qualification (AEC-Q100), providing superior long-term availability and supply chain stability compared to the obsolete main part.

Parameter Comparison

Engineering Selection Recommendations

The BZX884-C2V4,315 manufactured by Nexperia USA Inc. is the qualified substitute for the obsolete BZT52C2V4LP-TP. Selection of this substitute is supported by the following engineering factors:

Electrical Equivalence: All critical electrical parameters match or exceed the original specification. The nominal Zener voltage, impedance, reverse leakage current, and forward voltage characteristics are identical. The substitute's tighter tolerance (±5%) and higher power rating (250 mW) provide enhanced performance margins without introducing incompatibility.

Product Status and Availability: The substitute is classified as active with 20,633 units in stock, ensuring reliable supply chain access. The original part is obsolete with limited inventory, making transition to an active equivalent necessary for production continuity.

Compliance and Qualification: Both parts maintain ROHS3 compliance. The substitute carries AEC-Q100 automotive qualification, indicating rigorous reliability and quality assurance testing. This qualification enhances suitability for applications requiring automotive-grade components.

Package Compatibility: Both parts utilize the SOD-882 surface mount package, ensuring direct mechanical and electrical compatibility on existing printed circuit board layouts without redesign.

Frequently Asked Questions (FAQ)

Q: Can the BZX884-C2V4,315 be used as a direct replacement for the BZT52C2V4LP-TP?

A: Yes. The substitute part meets all critical electrical parameters including nominal Zener voltage (2.4 V), impedance (100 Ohms), reverse leakage current (50 µA @ 1 V), forward voltage (900 mV @ 10 mA), and operating temperature range (-65°C to 150°C). Both parts use the SOD-882 surface mount package, enabling direct substitution without circuit modification or board redesign.

Q: What are the differences between these two parts?

A: The substitute part exhibits three differences: (1) tighter voltage tolerance of ±5% compared to ±8.33%, (2) higher maximum power dissipation of 250 mW versus 100 mW, and (3) active product status with AEC-Q100 automotive qualification versus obsolete status. These differences represent performance enhancements that do not compromise compatibility.

Q: Does the higher power rating of the substitute affect circuit operation?

A: No. The higher power rating (250 mW) of the substitute does not negatively affect circuit operation. Power rating represents the maximum power the component can safely dissipate. A component with a higher power rating operates identically to one with a lower rating when actual power dissipation remains within the original specification. The substitute's 250 mW rating provides additional thermal margin and reliability.

Q: Are there any package or footprint differences?

A: No. Both parts use the SOD-882 surface mount package. Footprint, lead spacing, and mounting requirements are identical. No printed circuit board modifications are required.

Q: Why is the substitute part classified as automotive-grade?

A: The BZX884-C2V4,315 carries AEC-Q100 qualification, which is an automotive industry standard for component reliability and quality assurance. This qualification indicates the part has undergone rigorous testing for automotive applications. This classification does not restrict use in non-automotive applications; it indicates enhanced reliability suitable for demanding environments.

Q: Is the substitute part RoHS compliant?

A: Yes. The BZX884-C2V4,315 is ROHS3 compliant, matching the compliance status of the original part. Both parts meet environmental and hazardous substance restrictions.

Q: What is the inventory status of each part?

A: The original BZT52C2V4LP-TP has 1,084 units in stock but is classified as obsolete. The substitute BZX884-C2V4,315 has 20,633 units in stock and is classified as active, providing superior long-term availability.
