Engineering Selection Recommendations

All listed alternatives, including BZX84B16VLT116, BZX84B16VLYFHT116, and BZX84B16VLYT116, maintain active product status and meet ROHS3 and REACH compliance requirements. Automotive grade and AEC-Q101 qualification status are provided for models BZX84B16VLFHT116 and BZX84B16VLYFHT116. For applications requiring automotive grade or qualification, select parts explicitly carrying these grades. Supply chain flexibility can also be achieved through proper package compatibility as listed.

Frequently Asked Questions (FAQ)

Q: What electrical parameters must match for a substitute Zener diode in this category?
A: Substitute Zener diodes must have identical Zener voltage (16 V), tolerance, maximum power dissipation (250 mW), maximum impedance (40 Ohms), and reverse leakage current (100 nA @ 11 V).

Q: Are all substitute parts suitable for automotive applications?
A: Only parts specified as automotive grade and AEC-Q101 qualified (BZX84B16VLFHT116 and BZX84B16VLYFHT116) meet automotive requirements.

Q: How important is package compatibility for substitution?
A: Substitute diodes must be surface mountable and use an equivalent package type (TO-236-3, SC-59, SOT-23-3) and corresponding supplier device package (SSD3 or SOT-23) to ensure direct PCBA compatibility.

Q: What compliance requirements apply to all substitutes?
A: Each substitute listed is ROHS3 compliant, REACH unaffected, and has a moisture sensitivity level of 1 (unlimited), matching the main part's compliance profile.

Q: Is it necessary to check product status and inventory for substitutes?
A: Product status and inventory levels are provided. Ensure substitute selection from parts with an "Active" status for ongoing availability.
