Power - Max: 200 mW minimum
Mounting Type: Surface Mount
Package / Case: SC-90, SOD-323F compatible footprints

Secondary Compatibility Factors:

Impedance (Max) (Zzt): 80 Ohms or lower
Current - Reverse Leakage @ Vr: 2 µA @ 1 V or lower

Engineering Selection Recommendations

For Direct Replacement (Same Package, Same Power Rating):

UDZSTE-174.7B, UDZVTE-174.7B are the primary substitutes for the DZ2J04700L. Both parts maintain the SC-90/SOD-323F package footprint and 200 mW power rating. UDZSTE-174.7B offers tighter voltage tolerance (±2%) compared to the original ±5% specification. UDZVTE-174.7B provides equivalent electrical characteristics without specified tolerance. Both parts are ROHS3 compliant with active product status and unlimited moisture sensitivity rating.

For Automotive Applications:

UDZVFHTE-174.7B is qualified to AEC-Q101 automotive standards with automotive grade designation. Nominal voltage is 4.65 V (within the original ±5% tolerance band of 4.465 V to 4.935 V). This part maintains the SC-90/SOD-323F package and 200 mW power rating, suitable for automotive circuit protection applications.

For Higher Power Dissipation Requirements:

TFZVTR4.7B and YFZVFHTR4.7B provide 500 mW power rating in TUMD2M package (2-SMD, Flat Lead). These parts are suitable for applications requiring increased thermal margin. YFZVFHTR4.7B includes automotive grade and AEC-Q101 qualification. Both parts feature lower impedance (25 Ohms) compared to the original specification (80 Ohms).

Compliance Considerations:

All substitute parts are ROHS3 compliant and maintain MSL 1 (Unlimited) rating, ensuring compatibility with standard manufacturing and storage conditions. Automotive-qualified options (UDZVFHTE-174.7B, YFZVFHTR4.7B) are available for applications requiring AEC-Q101 certification.

Frequently Asked Questions (FAQ)

Q: Can UDZSTE-174.7B or UDZVTE-174.7B be used as direct replacements for DZ2J04700L?

A: Yes. Both parts maintain identical package footprint (SC-90, SOD-323F), power rating (200 mW), and nominal voltage (4.7 V). Electrical characteristics including reverse leakage current (2 µA @ 1 V) and impedance specifications are compatible. Both are active products with ROHS3 compliance.

Q: What is the voltage tolerance difference between DZ2J04700L and UDZSTE-174.7B?

A: DZ2J04700L specifies ±5% tolerance (4.465 V to 4.935 V range), while UDZSTE-174.7B specifies ±2% tolerance (4.606 V to 4.794 V range). The tighter tolerance of UDZSTE-174.7B provides improved voltage regulation characteristics within a narrower operating window.

Q: Can TFZVTR4.7B or YFZVFHTR4.7B be used in place of DZ2J04700L?

A: These parts are electrically compatible but use a different package (TUMD2M vs. SC-90/SOD-323F). PCB layout modifications are required. These parts offer 500 mW power rating versus 200 mW, providing increased thermal capability. Lower impedance (25 Ohms vs. 80 Ohms) results in improved voltage regulation.

Q: Are automotive-qualified alternatives available?

A: Yes. UDZVFHTE-174.7B and YFZVFHTR4.7B are both AEC-Q101 qualified with automotive grade designation. UDZVFHTE-174.7B maintains the original package (SC-90/SOD-323F) and power rating (200 mW). YFZVFHTR4.7B uses TUMD2M package with 500 mW rating.

Q: What is the impedance difference between substitute parts?

A: DZ2J04700L specifies 80 Ohms maximum impedance. UDZSTE-174.7B, UDZVTE-174.7B, and UDZVFHTE-174.7B specify 100 Ohms. TFZVTR4.7B and YFZVFHTR4.7B specify 25 Ohms. Lower impedance provides better voltage regulation and faster transient response.

Q: Do all substitute parts have the same reverse leakage current specification?

A: UDZSTE-174.7B, UDZVTE-174.7B, and UDZVFHTE-174.7B maintain 2 µA @ 1 V leakage current, identical to DZ2J04700L. TFZVTR4.7B and YFZVFHTR4.7B specify 5 µA @ 1 V, representing higher leakage in the 500 mW package variants.

Q: What is the operating temperature range for substitute parts?

A: UDZSTE-174.7B and UDZVTE-174.7B specify -55°C to 150°C operating range. UDZVFHTE-174.7B and YFZVFHTR4.7B specify 150°C maximum junction temperature (TJ). Operating temperature specifications should be verified against application requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts are ROHS3 compliant. DZ2J04700L is RoHS compliant. All parts maintain MSL 1 (Unlimited) moisture sensitivity rating, suitable for standard manufacturing and storage environments.
