Substitute Part Grouping Explanation

Substitution eligibility for the BZX84-A22,235 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Zener voltage: 22 V nominal
• Tolerance: ±1%
• Maximum power dissipation: 250 mW
• Impedance (Max): 55 Ohms
• Reverse leakage current: 50 nA @ 700 mV
• Forward voltage: 900 mV (Max) @ 10 mA
• Operating temperature range: -65°C to 150°C

Mechanical & Compliance Requirements:

• Mounting type: Surface Mount
• Package designation: TO-236-3, SC-59, SOT-23-3
• Automotive grade classification
• AEC-Q101 qualification
• RoHS3 compliance

The substitute part BZX84-A22,215 maintains identical electrical specifications and automotive qualification. The primary distinction is packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute is supplied in Bulk packaging. Both parts are manufactured by NXP USA Inc. (Nexperia USA Inc.) and are functionally interchangeable in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (BZX84-A22,235): The BZX84-A22,235 is the specified reference component. It is actively produced, carries full automotive qualification (AEC-Q101), and is supplied in Tape & Reel packaging suitable for automated assembly processes. RoHS3 compliance and MSL-1 rating are confirmed. This part is appropriate for production environments requiring documented traceability and standardized packaging formats.

Substitute Part Selection (BZX84-A22,215): The BZX84-A22,215 provides electrical and functional equivalence with identical Zener voltage, power rating, impedance, and temperature operating range. Both parts meet AEC-Q101 automotive qualification standards. The substitute differs only in packaging format (Bulk versus Tape & Reel). Selection of the substitute is appropriate when bulk packaging accommodates assembly requirements or when supply chain conditions favor this configuration. Both parts are manufactured by the same corporate entity (NXP/Nexperia).

Compliance Considerations: Both parts are classified as automotive-grade components with AEC-Q101 qualification, making them suitable for automotive circuit applications. The main part explicitly confirms ROHS3 compliance; compliance status for the substitute is not specified in the provided data.

Frequently Asked Questions (FAQ)

Q: Can BZX84-A22,215 be used as a direct replacement for BZX84-A22,235 in production?

A: Yes. Both parts are electrically identical with matching Zener voltage (22 V), power rating (250 mW), impedance (55 Ohms), and operating temperature range (-65°C to 150°C). Both carry AEC-Q101 automotive qualification. The only difference is packaging format: Tape & Reel versus Bulk. Substitution is valid provided the assembly process accommodates the bulk packaging format.

Q: What are the key electrical parameters that must match for substitution?

A: Substitution requires equivalence across: Zener voltage (22 V nominal), tolerance (±1%), maximum power dissipation (250 mW), impedance (55 Ohms maximum), reverse leakage current (50 nA @ 700 mV), forward voltage (900 mV @ 10 mA), and operating temperature range (-65°C to 150°C).

Q: Are both parts suitable for automotive applications?

A: Yes. Both BZX84-A22,235 and BZX84-A22,215 are classified as automotive-grade components and carry AEC-Q101 qualification, confirming suitability for automotive circuit designs.

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

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, optimized for automated pick-and-place assembly. Bulk packaging supplies loose components in quantities suitable for manual assembly or alternative handling processes. Both formats contain identical components; the difference is in delivery and handling format only.

Q: Can I mix BZX84-A22,235 and BZX84-A22,215 in the same production run?

A: Yes. Both parts are electrically and functionally equivalent. Mixing is permissible from a circuit performance standpoint. However, assembly process compatibility with different packaging formats should be evaluated based on specific manufacturing equipment and procedures.

Q: What inventory levels are available for each part?

A: BZX84-A22,235 (Tape & Reel) has 876 pieces in stock. BZX84-A22,215 (Bulk) has 3995 pieces in stock.

Q: Are there any temperature or environmental limitations I should consider?

A: Both parts operate across the identical temperature range of -65°C to 150°C. No differential environmental limitations exist between the two parts.
