Substitute Part Grouping Explanation

Substitution for the BZX84C6V8LT116 is determined strictly by matching the following provided parameters: nominal Zener voltage (6.8 V), tolerance (±5.88% or better), maximum power dissipation (250 mW), impedance (15 Ohms max), reverse leakage current, operating temperature (150°C TJ), mounting type (surface mount), compatible package formats (TO-236-3, SC-59, SOT-23-3), compliance status, and MSL. Substitute models are grouped only when they meet all these specified parameters, ensuring electrical and mechanical equivalence for drop-in replacement.

Engineering Selection Recommendations

All listed substitute Zener diodes possess an active status and comply with ROHS3 and REACH environmental standards. Each part is rated for an MSL of 1, allowing for unrestricted exposure during PCB assembly. ECCN and HTSUS codes are identical across all substitutes, confirming regulatory equivalence. Parts with automotive grade and AEC-Q101 qualification are included for designs requiring such certification. Only electrical and mechanical parameters explicitly provided have been considered for equivalency in the selection process.

Frequently Asked Questions (FAQ)

Q1: What electrical parameters must match for the BZX84C6V8LT116 to be substituted?
A1: Substitute parts must have a nominal Zener voltage of 6.8 V, maximum power dissipation of 250 mW, impedance not exceeding 15 Ohms, reverse leakage specifications, and a tolerance of ±5.88% or better.

Q2: Is package/case compatibility required for substitution?
A2: Yes. Substitute parts must be available in surface-mount packages compatible with TO-236-3, SC-59, or SOT-23-3 formats.

Q3: Can automotive-qualified Zener diodes be substituted for standard-grade versions?
A3: Yes. Automotive-grade and AEC-Q101 qualified versions can be substituted when other electrical and mechanical parameters match.

Q4: Are there any differences in environmental compliance or MSL ratings among substitutes?
A4: No. All substitutes are ROHS3 compliant, REACH unaffected, and have a Moisture Sensitivity Level rating of 1 (unlimited).

Q5: Is manufacturer substitution permitted if key parameters are matched?
A5: Yes. Provided all key electrical and mechanical parameters are identical, Zener diodes from different manufacturers within this category are valid substitutes.

Q6: Are there substitute parts with tighter tolerance?
A6: Yes. Some Nexperia USA Inc. substitutes offer ±5% tolerance, which is tighter than the ±5.88% of the main part.

Q7: What considerations are required for reverse leakage current when substituting?
A7: Reverse leakage current values differ by part number; they must be compared directly to ensure compatibility in the intended application. Only the values explicitly provided have been considered.
