Equivalent & Substitute Parts for DZ2J22000L

Part Overview

The DZ2J22000L is a 22 V, 200 mW Zener diode manufactured by Panasonic Electronic Components in the SC-90/SOD-323F surface mount package. This component is classified as discontinued at DiGi Electronics, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for ongoing production and repair applications. Substitute parts must satisfy the core electrical specifications: 22 V nominal Zener voltage, 200 mW maximum power dissipation, and surface mount packaging in compatible form factors.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DZ2J22000L is determined by the following critical parameters:

Primary Electrical Criteria:

• Voltage - Zener (Nom): 22 V (exact match required)
• Power - Max: 200 mW (minimum threshold; higher ratings are acceptable)
• Mounting Type: Surface Mount (required)
• Package / Case: SC-90, SOD-323F or mechanically compatible alternatives

Secondary Compliance Criteria:

• RoHS Status: RoHS3 Compliant or equivalent
• Moisture Sensitivity Level: 1 (Unlimited)
• ECCN: EAR99

All substitute parts listed maintain the 22 V Zener voltage specification. Three parts (UDZSTE-1722B, UDZVFHTE-1722B, UDZVTE-1722B) match the 200 mW power rating and SC-90/SOD-323F package footprint. One part (TFZGTR22B) provides 500 mW power rating with a different package form factor (TUMD2, 2-SMD Flat Lead) and is suitable for applications where higher power dissipation capacity is beneficial and mechanical space permits.

Parameter Comparison

Engineering Selection Recommendations

For Direct Footprint Replacement (SC-90/SOD-323F Package):

UDZVTE-1722B is the primary substitute. This part maintains identical package geometry, 22 V Zener voltage, and 200 mW power rating. It is active in production with ROHS3 compliance and unlimited moisture sensitivity rating. Operating temperature range of -55°C to 150°C covers standard industrial applications.

UDZSTE-1722B provides equivalent electrical performance with tighter tolerance (±2% versus ±5%) and identical package footprint. This part is suitable for applications requiring improved voltage accuracy.

UDZVFHTE-1722B is qualified to AEC-Q101 automotive standards with maximum junction temperature of 150°C. This part is specified for automotive-grade applications requiring formal qualification documentation.

For Applications Permitting Package Variation:

TFZGTR22B (Rohm Semiconductor) offers 500 mW power rating in a TUMD2 package (2-SMD Flat Lead). This substitute is applicable when circuit board layout accommodates the different package footprint and higher power dissipation capacity is required or beneficial for thermal margin.

Compliance Considerations:

All substitute parts are ROHS3 compliant and carry EAR99 ECCN classification, matching the regulatory status of the original component. All parts maintain MSL 1 (Unlimited) moisture sensitivity rating, eliminating special handling requirements.

Frequently Asked Questions (FAQ)

Q: Can TFZGTR22B replace DZ2J22000L in existing circuit board designs?

A: TFZGTR22B uses a different package form factor (TUMD2 versus SC-90/SOD-323F). Direct footprint substitution is not possible without circuit board modification. This part is suitable only for new designs or boards where the TUMD2 package footprint is available.

Q: What is the difference between UDZVTE-1722B and UDZSTE-1722B?

A: Both parts maintain 22 V Zener voltage, 200 mW power rating, and SC-90/SOD-323F package compatibility. UDZSTE-1722B specifies ±2% tolerance versus UDZVTE-1722B with unspecified tolerance. UDZSTE-1722B is preferred for applications requiring tighter voltage accuracy.

Q: Is UDZVFHTE-1722B suitable for non-automotive applications?

A: UDZVFHTE-1722B is qualified to AEC-Q101 automotive standards and carries automotive-grade designation. It is electrically compatible with non-automotive applications but is typically specified for automotive designs where qualification documentation is required.

Q: How do impedance differences affect circuit performance?

A: DZ2J22000L specifies 80 Ohms maximum impedance. UDZSTE-1722B, UDZVFHTE-1722B, and UDZVTE-1722B specify 100 Ohms maximum impedance. TFZGTR22B specifies 30 Ohms. Higher impedance values result in slightly increased output impedance in voltage regulation circuits. Lower impedance (TFZGTR22B) provides improved regulation characteristics.

Q: Are all substitute parts available in the same packaging formats?

A: UDZVTE-1722B, UDZSTE-1722B, and UDZVFHTE-1722B are available in Cut Tape (CT) and Digi-Reel formats. TFZGTR22B is available in Cut Tape (CT) and Digi-Reel formats. Packaging format selection depends on assembly process requirements and order quantity.

Q: What is the reverse leakage current difference between the main part and substitutes?

A: DZ2J22000L specifies 50 nA reverse leakage at 17 V. UDZSTE-1722B, UDZVFHTE-1722B, and UDZVTE-1722B specify 100 nA. TFZGTR22B specifies 200 nA. Higher reverse leakage values result in increased standby current in voltage regulation circuits. Applications sensitive to leakage current should specify UDZSTE-1722B or UDZVFHTE-1722B.
