BZV55C5V6-TP Equivalent & Substitute Parts

Part Overview

The BZV55C5V6-TP is a Zener diode rated at 5.6 V nominal voltage with 500 mW maximum power dissipation, manufactured by Micro Commercial Co in a Mini MELF surface mount package. This component is classified as obsolete, necessitating identification of active equivalent and substitute parts for ongoing design requirements and procurement continuity.

Substitute Part Grouping Explanation

Substitution of the BZV55C5V6-TP is determined by the following critical parameters: nominal Zener voltage of 5.6 V, maximum power rating of 500 mW, surface mount mounting type, and operating temperature range compatibility. Substitute parts must maintain the same voltage specification and power rating to ensure functional equivalence in circuit applications. Package compatibility is evaluated based on physical form factor and PCB footprint requirements. Tolerance, impedance characteristics, and reverse leakage current are secondary parameters that influence performance precision but do not preclude substitution when primary electrical specifications align.

Engineering Selection Recommendations

BZV55-C5V6,115 and BZV55-C5V6,135 (Nexperia USA Inc.) are the primary substitutes for the BZV55C5V6-TP. Both parts maintain identical nominal voltage (5.6 V), power rating (500 mW), and package compatibility (DO-213AC, MINI-MELF, SOD-80). These Nexperia devices offer improved tolerance (±5% versus ±7%), extended operating temperature range (-65°C to 200°C), and active product status. The BZV55-C5V6,115 is available in Cut Tape and Digi-Reel packaging, while BZV55-C5V6,135 is supplied in Tape & Reel format. Both are ROHS3 compliant.

BZT52C5V6-TP (Micro Commercial Co) is an active substitute with identical voltage and power specifications. This part uses SOD-123 package form factor, which differs from the original Mini MELF package and requires PCB layout modification. The BZT52C5V6-TP exhibits higher impedance (40 Ohms versus 25 Ohms) and increased reverse leakage current (1 µA @ 2 V versus 100 nA @ 1 V), making it suitable for applications where these parameter variations are acceptable.

BZV55C5V6 (Microchip Technology) maintains voltage and tolerance specifications but is supplied in DO-213AA glass package and carries RoHS non-compliant status. Power rating is not specified in available documentation. This part is not recommended for new designs requiring RoHS compliance.

Frequently Asked Questions (FAQ)

Q: Can BZV55-C5V6,115 or BZV55-C5V6,135 be used as direct replacements for BZV55C5V6-TP?

A: Yes. Both Nexperia parts maintain the same 5.6 V nominal voltage, 500 mW power rating, and Mini MELF package form factor. The primary differences are improved tolerance (±5%), extended temperature range, and active product status. No circuit redesign is required.

Q: What is the difference between BZV55-C5V6,115 and BZV55-C5V6,135?

A: Both parts are electrically identical. The difference is packaging format: BZV55-C5V6,115 is supplied in Cut Tape and Digi-Reel, while BZV55-C5V6,135 is supplied in Tape & Reel. Selection depends on procurement and assembly requirements.

Q: Can BZT52C5V6-TP replace BZV55C5V6-TP?

A: BZT52C5V6-TP is electrically compatible with identical voltage and power specifications. However, the SOD-123 package differs from Mini MELF, requiring PCB footprint modification. Higher impedance (40 Ohms) and reverse leakage current (1 µA @ 2 V) must be evaluated for circuit performance impact.

Q: Why is the Microchip BZV55C5V6 not recommended?

A: The Microchip part carries RoHS non-compliant status and lacks specified power rating documentation. For applications requiring RoHS compliance, Nexperia alternatives are preferred.

Q: What are the key parameters that determine substitution compatibility?

A: Nominal Zener voltage (5.6 V), maximum power dissipation (500 mW), surface mount mounting type, and operating temperature range are the primary criteria. Package form factor must be compatible with PCB layout. Tolerance, impedance, and leakage current are secondary parameters that influence precision but do not preclude substitution.

Q: Are all substitute parts ROHS3 compliant?

A: BZV55-C5V6,115, BZV55-C5V6,135, and BZT52C5V6-TP are ROHS3 compliant. The Microchip BZV55C5V6 is RoHS non-compliant and should not be used in applications requiring regulatory compliance.
