Key Parameters

Substitute Part Grouping Explanation

Substitution of the DZ2J030M0L is determined by the following critical parameters:

Primary Matching Criteria:

• Zener voltage: 3 V nominal
• Maximum power dissipation: 200 mW
• Mounting type: Surface Mount
• Package: SC-90/SOD-323F form factor
• Reverse leakage current: 50 µA @ 1 V

Secondary Compatibility Factors:

• Voltage tolerance (±2.5% to ±5% acceptable range)
• Impedance characteristics (95–120 Ohms maximum)
• RoHS and environmental compliance status
• Moisture sensitivity level: MSL 1

All substitute parts listed meet the primary matching criteria and operate within the specified electrical performance envelope. Tolerance variations and impedance differences remain within acceptable limits for standard voltage regulation and protection applications.

Engineering Selection Recommendations

BZT52-C3S_R1_00001 (Panjit International Inc.)

This substitute provides direct functional equivalence with 3 V nominal zener voltage and 200 mW power rating in the SOD-323F package. The ±5% tolerance is wider than the original ±2.5%, but remains within acceptable limits for general voltage regulation applications. The 95 Ohm impedance is lower than the original 120 Ohm specification, resulting in improved dynamic response characteristics. Product status is Active with ROHS3 compliance. Inventory availability is 5706 units.

UDZVFHTE-173.0B (Rohm Semiconductor)

This substitute meets all primary electrical specifications with 3 V nominal voltage and 200 mW power dissipation. The ±3.5% tolerance is tighter than the BZT52 alternative and closer to the original ±2.5% specification. Impedance matches the original at 120 Ohms. This part carries AEC-Q101 automotive qualification and is rated for automotive-grade applications. Product status is Active with ROHS3 compliance. Inventory availability is 11940 units.

UDZVTE-173.0B (Rohm Semiconductor)

This substitute provides 3 V nominal voltage and 200 mW power rating with operating temperature range of -55°C to 150°C. Tolerance and impedance specifications are not provided in the available data. Product status is Active with ROHS3 compliance. This part offers the highest inventory availability at 122300 units, supporting high-volume production requirements.

All three substitutes are RoHS compliant, maintain MSL 1 moisture sensitivity rating, and are available in the required SC-90/SOD-323F package configuration.

Frequently Asked Questions (FAQ)

Q: Can BZT52-C3S_R1_00001 replace DZ2J030M0L in all applications?

A: Yes. Both parts share identical 3 V nominal zener voltage, 200 mW power rating, and SOD-323F package. The ±5% tolerance of the BZT52 is wider than the original ±2.5%, but both operate within standard voltage regulation specifications. The lower impedance (95 Ohms vs. 120 Ohms) provides improved transient response.

Q: What is the difference between UDZVFHTE-173.0B and UDZVTE-173.0B?

A: Both are Rohm Semiconductor 3 V, 200 mW zener diodes in the UMD2 package. UDZVFHTE-173.0B includes AEC-Q101 automotive qualification and specifies ±3.5% tolerance. UDZVTE-173.0B does not include automotive qualification and does not specify tolerance in the available data. Both are electrically compatible with the original part.

Q: Are all substitutes pin-compatible with the original DZ2J030M0L?

A: Yes. All substitute parts use the SC-90/SOD-323F package configuration, which maintains identical pinout and footprint compatibility. Direct PCB substitution is possible without layout modifications.

Q: Which substitute offers the tightest voltage tolerance?

A: UDZVFHTE-173.0B provides ±3.5% tolerance, which is closer to the original ±2.5% specification than the BZT52-C3S_R1_00001 at ±5%. For applications requiring strict voltage regulation accuracy, UDZVFHTE-173.0B is the preferred selection.

Q: What is the impedance significance when selecting a substitute?

A: Impedance affects dynamic response to load transients. The original DZ2J030M0L and UDZVFHTE-173.0B both specify 120 Ohms maximum impedance. BZT52-C3S_R1_00001 specifies 95 Ohms, providing lower impedance and faster transient response. Lower impedance is generally beneficial for voltage regulation performance.

Q: Are all substitutes suitable for automotive applications?

A: UDZVFHTE-173.0B carries AEC-Q101 automotive qualification and is explicitly rated for automotive use. BZT52-C3S_R1_00001 and UDZVTE-173.0B do not include automotive qualification in the provided specifications. For automotive applications, UDZVFHTE-173.0B is the specified choice.

Q: Which substitute has the best inventory availability?

A: UDZVTE-173.0B offers the highest inventory at 122300 units, followed by UDZVFHTE-173.0B at 11940 units, and BZT52-C3S_R1_00001 at 5706 units. For high-volume production, UDZVTE-173.0B supports the largest procurement quantities.
