BZT52C15LP-TP Equivalent & Substitute Parts

Part Overview

The BZT52C15LP-TP is a Zener diode rated at 15 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 product status. Due to its obsolete classification and limited availability relative to active alternatives, identifying equivalent substitute parts is necessary for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BZT52C15LP-TP is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Zener voltage must match at 15 V nominal
• Operating temperature range must encompass -65°C ~ 150°C
• Forward voltage characteristic at 10 mA must not exceed 900 mV
• Surface mount technology requirement

Mechanical Compatibility Criteria:

• Surface mount package configuration
• RoHS3 compliance requirement
• MSL rating of 1 (Unlimited)

The BZX884-C15,315 manufactured by Nexperia USA Inc. satisfies these substitution criteria. While this substitute offers enhanced electrical performance characteristics (250 mW power rating, 15 Ohms impedance, 50 nA reverse leakage), it maintains electrical compatibility with the original part's core specifications and operates within the required temperature range.

Parameter Comparison

Engineering Selection Recommendations

The BZX884-C15,315 is an active product from Nexperia USA Inc. with AEC-Q100 automotive qualification, providing design continuity for the obsolete BZT52C15LP-TP. Both components maintain identical nominal Zener voltage (15 V), forward voltage characteristics (900 mV @ 10 mA), and operating temperature range (-65°C ~ 150°C). The substitute part offers improved electrical performance with higher power dissipation capability (250 mW versus 100 mW), lower impedance (15 Ohms versus 30 Ohms), and reduced reverse leakage current (50 nA versus 100 nA). Both components are ROHS3 compliant with MSL rating of 1. The substitute's active product status ensures long-term availability and supply chain stability compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can the BZX884-C15,315 directly replace the BZT52C15LP-TP in existing designs?

A: The BZX884-C15,315 is electrically compatible with the BZT52C15LP-TP based on matching Zener voltage (15 V), forward voltage characteristics (900 mV @ 10 mA), and operating temperature range (-65°C ~ 150°C). Both components are surface mount devices with ROHS3 compliance and MSL rating of 1. The substitute's enhanced performance characteristics (higher power rating, lower impedance, reduced leakage) do not create incompatibility in applications designed for the original part.

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

A: The BZX884-C15,315 provides superior electrical performance with 250 mW maximum power dissipation compared to 100 mW in the BZT52C15LP-TP. Impedance is reduced from 30 Ohms to 15 Ohms, and reverse leakage current is lower at 50 nA versus 100 nA. Zener voltage tolerance is tighter at ±5% versus ±6%. These differences represent performance improvements that maintain backward compatibility.

Q: Are there package considerations when substituting these parts?

A: Both components are surface mount devices. The BZT52C15LP-TP uses SOD-882 package, while the BZX884-C15,315 uses DFN1006-2 package. Physical dimensions and footprint characteristics differ between these packages. PCB layout and component placement must be verified for compatibility with the substitute package configuration.

Q: What compliance certifications apply to the substitute part?

A: The BZX884-C15,315 is ROHS3 compliant, AEC-Q100 qualified for automotive applications, and REACH unaffected. The original BZT52C15LP-TP is ROHS3 compliant. Both components carry MSL rating of 1 (Unlimited) for moisture sensitivity.

Q: Why is the BZT52C15LP-TP classified as obsolete?

A: The BZT52C15LP-TP is designated as obsolete product status by the manufacturer. The BZX884-C15,315 maintains active product status, ensuring continued availability, manufacturing support, and supply chain reliability for applications requiring 15 V Zener diodes in surface mount configurations.
