Engineering Selection Recommendations

BZX84C16LT1G (onsemi)

This substitute maintains manufacturer continuity with onsemi and provides active product status. The part operates across an extended temperature range (-65°C to 150°C) compared to the main part. Power dissipation is reduced to 225 mW, which is acceptable for applications not requiring the full 350 mW capacity of the obsolete part. All electrical parameters remain compatible. RoHS3 compliance provides regulatory advantage for new designs.

BZX84-C16,215 (Nexperia USA Inc.)

This substitute offers automotive-grade qualification (AEC-Q101) and is available in high inventory (138,936 pcs). The voltage tolerance is tightened to ±5%, providing improved regulation accuracy. Power dissipation of 250 mW accommodates most standard applications. Extended temperature range (-65°C to 150°C) and RoHS3 compliance support modern design requirements.

BZX84-C16,235 (Nexperia USA Inc.)

This substitute is functionally equivalent to BZX84-C16,215 with identical electrical specifications and automotive qualification. The primary distinction is packaging format (Cut Tape & Digi-Reel versus Tape & Reel). Selection between these two Nexperia variants depends on procurement and assembly requirements.

All three substitutes are electrically compatible with the BZX84C16_D87Z within the specified operating parameters and maintain the same SOT-23-3 package footprint for direct board-level replacement.

Frequently Asked Questions (FAQ)

Q: Can BZX84C16LT1G directly replace BZX84C16_D87Z in existing designs?

A: Yes. Both parts share identical impedance (40 Ohms), reverse leakage current (50 nA @ 11.2 V), forward voltage (900 mV @ 10 mA), and package type (SOT-23-3). The zener voltage difference (16 V nominal versus 16.2 V nominal) falls within acceptable tolerance ranges for voltage regulation applications. The reduced power rating (225 mW versus 350 mW) requires verification that circuit power dissipation does not exceed this limit.

Q: What is the voltage difference between the main part and substitutes?

A: The BZX84C16_D87Z is rated at 16.2 V nominal with ±6% tolerance, yielding a range of 15.25 V to 17.15 V. The substitute parts are rated at 16 V nominal with either ±6% (BZX84C16LT1G) or ±5% (Nexperia variants), yielding ranges of 15.04 V to 16.96 V (±6%) or 15.2 V to 16.8 V (±5%). These ranges overlap substantially, making substitution acceptable for standard voltage regulation circuits.

Q: Are the Nexperia parts suitable for automotive applications?

A: Yes. Both BZX84-C16,215 and BZX84-C16,235 carry automotive-grade designation with AEC-Q101 qualification, making them suitable for automotive and high-reliability applications. The onsemi BZX84C16LT1G does not carry automotive qualification but remains suitable for industrial and consumer applications.

Q: What is the difference between BZX84-C16,215 and BZX84-C16,235?

A: These parts are electrically and functionally identical. The difference lies in packaging format: BZX84-C16,215 is supplied in Tape & Reel (TR) format, while BZX84-C16,235 is supplied in Cut Tape (CT) & Digi-Reel format. Selection depends on assembly equipment compatibility and procurement preferences.

Q: Is the reduced power rating of BZX84C16LT1G (225 mW) a limitation?

A: The reduced power rating applies only if the circuit dissipates more than 225 mW in the zener diode. For typical voltage regulation and protection applications, 225 mW is sufficient. Applications requiring sustained power dissipation above 225 mW should use BZX84-C16,215 or BZX84-C16,235 (250 mW rating).

Q: Are all substitutes RoHS compliant?

A: Yes. All three substitute parts are ROHS3 compliant. The main part (BZX84C16_D87Z) does not specify RoHS status, but substitutes provide compliance assurance for modern manufacturing and environmental requirements.

Q: Can these parts be used interchangeably in production?

A: Yes, within the constraints of power dissipation requirements and procurement availability. All parts share identical package footprints (SOT-23-3), electrical characteristics (impedance, leakage, forward voltage), and thermal operating ranges. Zener voltage tolerance overlap ensures functional compatibility. Production changeover requires only verification that circuit power dissipation does not exceed the substitute part's maximum rating.
