Key Parameters

Substitute Part Grouping Explanation

Substitution of the VLZ8V2-GS08 is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Parameters (Critical for Function):

• Voltage - Zener (Nom) (Vz): 8.2 V
• Power - Max: 500 mW
• Impedance (Max) (Zzt): 8 Ohms
• Voltage - Forward (Vf) (Max) @ If: 1.5 V @ 200 mA
• Operating Temperature Range: -65°C ~ 175°C

Mechanical Parameters (Critical for Installation):

• Mounting Type: Surface Mount
• Package / Case: SOD-80 variant

Compliance Parameters (Critical for Qualification):

• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant

The substitute part TLZ8V2-GS08 meets all electrical and compliance requirements. The package variant differs (MiniMELF vs. QuadroMELF), both within the SOD-80 family, and represents the active production equivalent.

Parameter Comparison

Engineering Selection Recommendations

The TLZ8V2-GS08 is the direct electrical equivalent to the VLZ8V2-GS08. Both components share identical electrical specifications across all critical parameters: 8.2 V nominal Zener voltage, 500 mW maximum power dissipation, 8 Ohms maximum impedance, and identical forward voltage characteristics.

The primary distinction is product status: the VLZ8V2-GS08 is Obsolete, while the TLZ8V2-GS08 is Active. The TLZ8V2-GS08 is manufactured by the same supplier and maintains ROHS3 compliance and MSL 1 rating.

The package variant difference (QuadroMELF vs. MiniMELF) represents a physical form factor change within the SOD-80 family. Both are surface mount configurations. PCB layout and footprint modifications are required to accommodate this package transition.

For applications requiring automotive-grade qualification and AEC-Q101 certification, verification of the TLZ8V2-GS08 qualification status with the manufacturer is necessary, as this information is not provided in the substitute part data.

Frequently Asked Questions (FAQ)

Q: Can the TLZ8V2-GS08 be used as a direct replacement for the VLZ8V2-GS08?

A: The TLZ8V2-GS08 is electrically equivalent across all specified parameters. However, the package variant (MiniMELF vs. QuadroMELF) requires PCB footprint modification. Both are SOD-80 surface mount packages but have different physical dimensions and lead configurations.

Q: What is the difference between SOD-80 QuadroMELF and SOD-80 MiniMELF?

A: Both are SOD-80 package variants for surface mount Zener diodes. QuadroMELF and MiniMELF differ in physical dimensions and lead geometry. The specific dimensional differences are not provided in the input data. Consult the respective datasheets for exact footprint specifications.

Q: Why is the VLZ8V2-GS08 marked as Obsolete?

A: The VLZ8V2-GS08 is classified as Obsolete by the manufacturer. The TLZ8V2-GS08 represents the active production equivalent from the same manufacturer.

Q: Are there any compliance differences between the two parts?

A: Both parts are ROHS3 compliant with MSL 1 rating. Automotive grade and AEC-Q101 qualification status for the TLZ8V2-GS08 is not specified in the provided data. Confirm qualification requirements with the manufacturer if automotive applications are involved.

Q: What inventory status should I consider?

A: The VLZ8V2-GS08 has 734 pieces in stock (Obsolete status). The TLZ8V2-GS08 has 1111 pieces in stock (Active status). For long-term supply chain planning, the Active status of the TLZ8V2-GS08 provides greater availability assurance.
