BZT52C3V6LP-TP Equivalent & Substitute Parts

Part Overview

The BZT52C3V6LP-TP is a Zener diode manufactured by Micro Commercial Co, rated at 3.6 V nominal with 100 mW maximum power dissipation in a surface mount SOD-882 package. This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support, production continuity, and component sourcing.

Zener diodes in this voltage and power class are used for voltage regulation, overvoltage protection, and reference voltage applications in low-power circuits. The obsolete status of the BZT52C3V6LP-TP necessitates evaluation of active alternative components that maintain electrical and mechanical compatibility with existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BZT52C3V6LP-TP is determined by strict alignment of the following critical parameters:

Electrical Compatibility Requirements:

• Zener voltage (Vz) must be 3.6 V nominal to maintain voltage regulation function
• Tolerance specification must support circuit design margins
• Impedance (Zzt) must remain within acceptable limits for voltage stability
• Reverse leakage current must not exceed specified values to prevent circuit performance degradation
• Forward voltage characteristics must be compatible with circuit biasing conditions
• Operating temperature range must encompass the application environment

Mechanical and Assembly Compatibility Requirements:

• Surface mount mounting type is required for PCB assembly compatibility
• Package footprint must be compatible with existing PCB layout and assembly equipment
• RoHS3 compliance is mandatory for regulatory and supply chain requirements

Product Status Consideration:

• Active product status is preferred to ensure long-term availability and supply chain stability
• Obsolete components present sourcing risk and should be replaced where possible

The substitute part BZX884-C3V6,315 meets all critical electrical parameters while offering enhanced power rating and active product status.

Engineering Selection Recommendations

Primary Substitute: BZX884-C3V6,315

The BZX884-C3V6,315 manufactured by NXP USA Inc. is the qualified substitute for the obsolete BZT52C3V6LP-TP. This substitution is supported by the following factors:

Electrical Equivalence: All critical electrical parameters align with the original component: 3.6 V nominal zener voltage, 90 Ohm maximum impedance, 5 µA reverse leakage current, and 900 mV forward voltage. The substitute features a tighter tolerance specification (±5% versus ±5.56%), which provides improved voltage accuracy and is compatible with circuit design margins.

Enhanced Power Rating: The BZX884-C3V6,315 provides 250 mW maximum power dissipation compared to the original 100 mW rating. This higher power capability supports the same applications as the original component and extends applicability to circuits with higher current requirements, provided thermal management is adequate.

Mechanical Compatibility: Both components utilize identical surface mount packaging (SOD-882) and mounting type, ensuring direct PCB footprint compatibility without layout modifications.

Product Status and Supply: The BZX884-C3V6,315 maintains active product status with established supply chain availability (100,476 units in stock), eliminating the sourcing constraints associated with the obsolete BZT52C3V6LP-TP.

Regulatory Compliance: The original component is ROHS3 compliant. Verification of RoHS compliance status for the substitute component is recommended during procurement to ensure regulatory alignment with end-use requirements.

Frequently Asked Questions (FAQ)

Q: Can the BZX884-C3V6,315 directly replace the BZT52C3V6LP-TP without PCB modifications?

A: Yes. Both components share identical SOD-882 package geometry and surface mount footprint. No PCB layout changes are required for mechanical substitution. Electrical parameters are compatible for direct functional replacement.

Q: What is the significance of the higher 250 mW power rating on the BZX884-C3V6,315?

A: The substitute component can dissipate more power than the original 100 mW specification. In applications operating at or below the original 100 mW design point, the higher rating provides additional thermal margin and reliability. The substitute is fully compatible with circuits designed for the original 100 mW component.

Q: Are the voltage tolerance specifications compatible?

A: Yes. The substitute features ±5% tolerance compared to the original ±5.56%. The tighter tolerance of the substitute is compatible with circuit designs based on the original component's tolerance specification.

Q: Does the impedance specification affect circuit performance?

A: Both components specify 90 Ohm maximum impedance, ensuring identical voltage regulation characteristics and circuit stability performance. No circuit behavior changes result from this substitution.

Q: What is the impact of different manufacturers on component reliability?

A: Both Micro Commercial Co and NXP USA Inc. are established semiconductor manufacturers. The BZX884-C3V6,315 from NXP maintains active product status with established quality and supply chain infrastructure, supporting long-term design reliability.

Q: Should RoHS compliance be verified before procurement?

A: Yes. The original BZT52C3V6LP-TP is ROHS3 compliant. RoHS compliance status for the BZX884-C3V6,315 should be confirmed with the supplier to ensure alignment with regulatory and customer requirements for the end application.

Q: Are there any thermal management considerations for the higher power rating?

A: The substitute's higher power rating does not require additional thermal management for applications operating within the original 100 mW design envelope. For applications approaching or exceeding 100 mW, standard surface mount thermal design practices apply to both components.
