DZ2W22000L Equivalent & Substitute Parts

Part Overview

The DZ2W22000L is a 22 V, 1 W Zener diode manufactured by Panasonic Electronic Components in the SOD-123F surface mount package. This component is designed for voltage regulation and protection applications requiring precise Zener voltage characteristics at 22 V nominal with ±5% tolerance. The part is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives that maintain electrical and mechanical compatibility for ongoing production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DZ2W22000L is determined by the following critical parameters:

Electrical Compatibility Criteria:

• Zener voltage nominal value within acceptable circuit tolerance
• Power dissipation rating of 1 W minimum
• Reverse leakage current specification at rated voltage
• Forward voltage characteristics for bidirectional applications

Mechanical Compatibility Criteria:

• Surface mount package type SOD-123F
• Moisture sensitivity level MSL 1 or equivalent
• RoHS compliance status

The substitute parts KDZVTFTR22B and KDZVTR22B from Rohm Semiconductor are grouped as equivalents based on matching power rating (1 W), identical package format (SOD-123F), and comparable reverse leakage specifications. Both substitutes operate at 23.25 V nominal Zener voltage, which represents a 5.68% deviation from the DZ2W22000L specification. This voltage differential falls within typical circuit tolerance margins for general voltage regulation applications but requires circuit-level validation for precision applications with tight voltage tolerance requirements.

Engineering Selection Recommendations

KDZVTFTR22B Selection Criteria:

The KDZVTFTR22B is an active product with automotive-grade qualification (AEC-Q101) and ROHS3 compliance. This part is suitable for applications requiring enhanced reliability documentation and automotive supply chain traceability. The automotive qualification provides additional process control and quality assurance documentation compared to standard industrial-grade components. Inventory availability is 3313 units.

KDZVTR22B Selection Criteria:

The KDZVTR22B is an active product with ROHS3 compliance and standard industrial-grade qualification. This part is suitable for general industrial applications where automotive qualification is not required. Inventory availability is 2709 units.

Voltage Consideration:

Both substitute parts operate at 23.25 V nominal Zener voltage compared to the original 22 V specification. The 1.25 V differential (5.68% above nominal) must be evaluated against circuit design margins. Applications with voltage regulation windows centered on 22 V may experience output voltage shifts within the substitute parts' tolerance band. Circuit-level analysis is required to confirm acceptability in precision voltage reference or protection applications.

Compliance Status:

Both substitute parts exceed the original RoHS compliance requirement with ROHS3 certification and maintain MSL 1 moisture sensitivity rating, ensuring compatibility with standard surface mount assembly processes.

Frequently Asked Questions (FAQ)

Q: Can KDZVTFTR22B and KDZVTR22B be used interchangeably with DZ2W22000L?

A: Both Rohm parts share identical package format (SOD-123F), power rating (1 W), and reverse leakage specifications. The primary difference is Zener voltage: 23.25 V versus 22 V. Interchangeability depends on circuit tolerance for this 1.25 V voltage differential. Applications with tight voltage regulation windows require circuit validation before substitution.

Q: What is the difference between KDZVTFTR22B and KDZVTR22B?

A: KDZVTFTR22B includes automotive-grade qualification (AEC-Q101) and specified tolerance of ±5.68%. KDZVTR22B is industrial-grade without specified tolerance. Both operate at 23.25 V nominal and share identical electrical performance in non-automotive applications. Selection depends on supply chain requirements and documentation needs.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both KDZVTFTR22B and KDZVTR22B are ROHS3 compliant, exceeding the original DZ2W22000L RoHS compliance requirement. Both maintain MSL 1 moisture sensitivity rating.

Q: What is the impact of the 23.25 V Zener voltage on circuit performance?

A: The 1.25 V increase represents a 5.68% deviation from the original 22 V specification. In voltage regulation applications, this shifts the output voltage upward by approximately 5.68%. In protection applications, the threshold voltage increases correspondingly. Circuit design margins must accommodate this shift. Precision applications with voltage tolerance windows narrower than ±5.68% require detailed circuit analysis.

Q: Are both substitute parts available in the same packaging format?

A: Yes. Both KDZVTFTR22B and KDZVTR22B are supplied in SOD-123F surface mount package with Cut Tape (CT) and Digi-Reel® packaging options, matching the original DZ2W22000L package format.

Q: What is the reverse leakage current specification difference?

A: The original DZ2W22000L specifies 10 µA @ 16 V reverse leakage. Both substitute parts specify 10 µA @ 17 V. The 1 V measurement voltage difference reflects the higher Zener voltage of the substitute parts. Leakage current magnitude remains equivalent at 10 µA.
