BZX84-C22/LF1R Zener Diode Equivalent & Substitute Parts

Part Overview

The BZX84-C22/LF1R is a 22 V, 250 mW Zener diode manufactured by NXP USA Inc. in the SOT-23 (TO-236AB) surface mount package. This component is classified as an automotive-grade diode with AEC-Q101 qualification and is currently in active production status.

Substitute Part Grouping Explanation

Substitution eligibility for the BZX84-C22/LF1R is determined by the following critical parameters:

Primary Equivalence Criteria:

Zener voltage (Vz): 22 V nominal
Maximum power dissipation: 250 mW
Package type: SOT-23 (TO-236AB) surface mount
Operating temperature range: -65°C to 150°C
Automotive grade with AEC-Q101 qualification

Secondary Variation Parameter:

Tolerance: ±1%, ±2%, or ±5% are acceptable variations

All substitute parts listed maintain identical zener voltage, power rating, impedance, forward voltage characteristics, and thermal operating range. Variations in tolerance and packaging format (Bulk vs. Tape & Reel) do not affect electrical substitutability. Manufacturer differences (NXP USA Inc. vs. Nexperia USA Inc.) are permitted as both entities produce equivalent automotive-qualified components to the same specifications.

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): BZX84-C22,235 is the direct equivalent to BZX84-C22/LF1R, maintaining identical tolerance (±5%), zener voltage (22 V), power rating (250 mW), and SOT-23 package format. Both parts carry ROHS3 compliance, AEC-Q101 automotive qualification, and unlimited MSL rating.

For Tighter Tolerance Requirements: BZX84-A22,215 provides ±1% tolerance specification while maintaining all other electrical and thermal parameters. This part is suitable when circuit design requires reduced zener voltage variation.

For Intermediate Tolerance with Expanded Availability: BZX84-B22,215 and BZX84-B22,235 offer ±2% tolerance with significantly higher inventory levels (183100 Pcs and 9012 Pcs respectively). Both maintain automotive AEC-Q101 qualification and are supplied in Tape & Reel format.

For Equivalent Tolerance with Alternative Packaging: BZX84-C22,215 matches the ±5% tolerance of the primary part and is available in Tape & Reel packaging format, suitable for automated assembly processes requiring continuous reel supply.

All substitute parts maintain identical operating temperature range (-65°C to 150°C), forward voltage characteristics (900 mV @ 10 mA), reverse leakage current (50 nA @ 15.4 V), and impedance specifications (55 Ω maximum).

Frequently Asked Questions (FAQ)

Q: Can BZX84-A22,215 replace BZX84-C22/LF1R in all applications?

A: Yes. BZX84-A22,215 is electrically equivalent with superior tolerance specification (±1% vs. ±5%). The tighter tolerance does not create incompatibility; it provides enhanced precision. All other parameters—zener voltage, power rating, impedance, thermal range, and automotive qualification—are identical.

Q: What is the difference between Bulk and Tape & Reel packaging?

A: Bulk packaging is suitable for manual assembly or small-quantity applications. Tape & Reel packaging is designed for automated pick-and-place assembly equipment. Electrical performance is identical; the difference is purely in supply format and handling method.

Q: Are NXP USA Inc. and Nexperia USA Inc. parts interchangeable?

A: Yes. Both manufacturers produce equivalent automotive-grade zener diodes to identical electrical specifications and AEC-Q101 qualification standards. The parts are functionally interchangeable.

Q: Does the ±2% tolerance of BZX84-B22 series affect circuit compatibility?

A: No. The ±2% tolerance falls within acceptable zener voltage variation for standard circuit applications. The nominal 22 V specification is maintained across all tolerance grades (±1%, ±2%, ±5%). Selection should be based on circuit design requirements for voltage regulation precision.

Q: Can I use BZX84-C22,215 (Tape & Reel) in place of BZX84-C22/LF1R (Bulk)?

A: Yes. Both parts are electrically identical with matching ±5% tolerance and 22 V zener voltage. The only difference is packaging format. Tape & Reel is suitable for automated assembly; Bulk is suitable for manual or small-batch assembly.

Q: Are all substitute parts ROHS3 compliant and AEC-Q101 qualified?

A: Yes. All listed substitute parts carry ROHS3 compliance and AEC-Q101 automotive qualification, matching the primary part's compliance status.
