BZT52C10LP-TP Equivalent & Substitute Parts

Part Overview

The BZT52C10LP-TP is a Zener diode manufactured by Micro Commercial Co, rated at 10 V nominal with 100 mW maximum power dissipation in a surface mount SOD-882 package. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing design requirements and procurement continuity. Substitute parts must maintain electrical compatibility across voltage regulation, power handling, and thermal operating ranges while accommodating available packaging options.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BZT52C10LP-TP is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Nominal Zener voltage of 10 V
• Reverse leakage current of 200 nA @ 7 V
• Forward voltage of 900 mV @ 10 mA
• Operating temperature range of -65°C to 150°C

Mechanical Compatibility Criteria:

• Surface mount mounting type
• SOD-882 package footprint

Acceptable Variations:

• Voltage tolerance may be tighter (±5% acceptable for ±6% requirement)
• Maximum power dissipation may exceed 100 mW (higher power rating is acceptable)
• Impedance may be lower than 20 Ohms (lower impedance is acceptable)

The BZX884-C10,315 from NXP Semiconductors meets all substitution criteria while offering improved specifications in power handling and impedance characteristics.

Engineering Selection Recommendations

The BZX884-C10,315 is a direct functional substitute for the obsolete BZT52C10LP-TP. Selection of the NXP Semiconductors part is supported by the following factors:

Product Status: The BZX884-C10,315 maintains active product status with established supply chain availability (3,028,704 units in stock), whereas the BZT52C10LP-TP is obsolete with limited remaining inventory (1,110 units).

Electrical Equivalence: Both parts maintain identical nominal Zener voltage (10 V), reverse leakage current (200 nA @ 7 V), forward voltage (900 mV @ 10 mA), and operating temperature range (-65°C to 150°C).

Enhanced Specifications: The BZX884-C10,315 provides superior performance through increased maximum power dissipation (250 mW versus 100 mW) and reduced impedance (10 Ohms versus 20 Ohms), enabling operation in higher power applications without thermal derating.

Compliance: The BZX884-C10,315 maintains REACH Unaffected status and equivalent moisture sensitivity classification (MSL 1), ensuring regulatory and environmental compatibility.

Package Compatibility: Both parts utilize the SOD-882 surface mount package, permitting direct PCB footprint substitution without layout modification.

Frequently Asked Questions (FAQ)

Q: Can the BZX884-C10,315 be used as a direct replacement for the BZT52C10LP-TP in existing designs?

A: Yes. The BZX884-C10,315 maintains identical electrical characteristics for nominal Zener voltage, reverse leakage current, forward voltage, and operating temperature range. The SOD-882 package footprint is identical, permitting direct PCB substitution without design modification.

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), and enhanced specifications in the substitute part. The BZX884-C10,315 offers 250 mW maximum power dissipation compared to 100 mW, and 10 Ohms impedance compared to 20 Ohms. Voltage tolerance is tighter (±5% versus ±6%).

Q: Is the higher power rating of the BZX884-C10,315 a concern for applications designed for 100 mW?

A: No. A higher maximum power rating does not create compatibility issues. Applications designed for 100 mW operation will function identically with a 250 mW rated component. The substitute part will not dissipate more power than the circuit design specifies.

Q: Are there any thermal or reliability differences between these parts?

A: Both parts operate across the identical temperature range (-65°C to 150°C). The BZX884-C10,315 has lower impedance (10 Ohms versus 20 Ohms), which may result in slightly improved voltage regulation characteristics. Both parts maintain MSL 1 moisture sensitivity classification.

Q: What is the impact of the tighter tolerance (±5% versus ±6%) in the substitute part?

A: The ±5% tolerance of the BZX884-C10,315 is tighter than the ±6% specification of the BZT52C10LP-TP. This represents improved manufacturing precision and is fully compatible with applications designed for ±6% tolerance.

Q: Are there any supply chain considerations for this substitution?

A: The BZX884-C10,315 has significantly higher inventory availability (3,028,704 units) compared to the obsolete BZT52C10LP-TP (1,110 units). This ensures long-term procurement continuity and reduces supply risk.
