Substitute Part Grouping Explanation

Substitution of the VLZ10-GS08 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

Zener voltage: 10 V nominal
Maximum power dissipation: 500 mW
Maximum impedance: 8 Ohms
Forward voltage: 1.5 V maximum at 200 mA
Operating temperature range: -65°C to 175°C

Mechanical Equivalence Criteria:

Surface mount configuration
SOD-80 package family compatibility
Automotive grade classification
AEC-Q101 qualification

Compliance Equivalence Criteria:

RoHS3 compliance
Moisture Sensitivity Level 1
REACH unaffected status

The TLZ10-GS08 meets all electrical and compliance requirements for direct substitution. Both components share identical electrical specifications and automotive qualification. The primary distinction is the packaging variant designation (QuadroMELF versus MiniMELF) within the SOD-80 family, with the substitute supplied in Tape & Reel format.

Engineering Selection Recommendations

The TLZ10-GS08 is a direct electrical and functional equivalent to the obsolete VLZ10-GS08. Both components are manufactured by Vishay General Semiconductor - Diodes Division and carry identical electrical specifications, automotive grade classification, and AEC-Q101 qualification.

Selection Basis:

The substitute part maintains full compliance with RoHS3 and REACH requirements. Both components operate across the identical temperature range (-65°C to 175°C) and deliver equivalent electrical performance in zener voltage regulation applications.

The TLZ10-GS08 is currently in active production status with confirmed inventory availability (884 pieces), whereas the VLZ10-GS08 is obsolete. The packaging variant difference (MiniMELF versus QuadroMELF) represents a refinement within the SOD-80 family and does not affect electrical performance or circuit compatibility.

For applications requiring the VLZ10-GS08, the TLZ10-GS08 provides direct substitution without circuit redesign or performance compromise.

Frequently Asked Questions (FAQ)

Q: Are the VLZ10-GS08 and TLZ10-GS08 electrically identical?

A: Yes. Both components share identical zener voltage (10 V), maximum power dissipation (500 mW), impedance (8 Ohms maximum), forward voltage characteristics (1.5 V @ 200 mA), and operating temperature range (-65°C to 175°C).

Q: What is the difference between QuadroMELF and MiniMELF packaging?

A: Both are SOD-80 package variants manufactured by Vishay. The designation reflects internal package geometry refinements. Both variants are mechanically and electrically compatible within the SOD-80 family and function identically in circuit applications.

Q: Can the TLZ10-GS08 be used as a direct replacement without PCB modification?

A: Yes. The TLZ10-GS08 is footprint-compatible with the VLZ10-GS08 within SOD-80 specifications. No circuit redesign or PCB layout changes are required.

Q: Does the TLZ10-GS08 meet automotive qualification requirements?

A: Yes. The TLZ10-GS08 carries Automotive grade classification and AEC-Q101 qualification, matching the original VLZ10-GS08 specification.

Q: What is the primary reason for substitution?

A: The VLZ10-GS08 is classified as obsolete. The TLZ10-GS08 is an active production component from the same manufacturer with identical electrical and compliance specifications, ensuring long-term supply availability.

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

A: No. Both components are ROHS3 compliant, REACH unaffected, and carry Moisture Sensitivity Level 1 (Unlimited). Compliance profiles are identical.
