Key Parameters

Substitute Part Grouping Explanation

Substitution of the DZ2S047M0L is determined by equivalence across the following critical parameters:

Primary Substitution Criteria:

• Zener voltage nominal value within acceptable tolerance band
• Maximum power dissipation rating of 150 mW or greater
• Surface mount packaging in SC-79/SOD-523 form factor
• Reverse leakage current specification of 2 µA @ 1 V or lower
• RoHS compliance status

Secondary Compatibility Factors:

• Impedance (Zzt) maximum rating
• Forward voltage characteristics
• Moisture sensitivity level MSL 1 or equivalent

Two substitute parts meet these criteria with active product status and confirmed inventory availability. Both alternatives maintain the 150 mW power rating, surface mount configuration, and equivalent reverse leakage specifications. Zener voltage nominal values differ slightly but remain within acceptable operating ranges for typical voltage regulation applications.

Engineering Selection Recommendations

EDZVT2R4.7B (Rohm Semiconductor) - Primary Substitute

This part provides exact nominal zener voltage matching at 4.7 V with tighter tolerance specification (±2% versus ±2.5%). The EDZVT2R4.7B maintains identical 150 mW power rating, reverse leakage current, and SC-79/SOD-523 packaging. Product status is active with 18,178 units in stock. ROHS3 compliance and REACH unaffected status confirm regulatory alignment. Operating temperature range of -55°C to 150°C supports extended thermal applications. The EDZV series designation indicates established product maturity.

EDZVFHT2R4.7B (Rohm Semiconductor) - Secondary Substitute

This alternative provides 4.65 V nominal zener voltage with ±2.15% tolerance, representing a 0.05 V deviation from the original specification. The 150 mW power rating and SC-79/SOD-523 package maintain mechanical and thermal compatibility. AEC-Q101 automotive qualification and 150°C maximum junction temperature rating indicate enhanced reliability grading. Product status is active with 1,065 units in stock. ROHS3 compliance and REACH unaffected status confirm regulatory alignment. Selection of this part is appropriate for applications requiring automotive-grade qualification.

Frequently Asked Questions (FAQ)

Q: Can EDZVT2R4.7B directly replace DZ2S047M0L without circuit modification?

A: Yes. The EDZVT2R4.7B provides identical 4.7 V nominal zener voltage, 150 mW power rating, and SC-79/SOD-523 package configuration. The ±2% tolerance is tighter than the original ±2.5%, ensuring improved voltage regulation accuracy. No circuit modifications are required for direct substitution.

Q: What is the voltage difference between DZ2S047M0L and EDZVFHT2R4.7B?

A: The EDZVFHT2R4.7B specifies 4.65 V nominal zener voltage compared to 4.7 V for the DZ2S047M0L. This represents a 0.05 V (approximately 1.1%) deviation. Within the combined tolerance bands (±2.5% and ±2.15%), both parts overlap in acceptable operating range for most voltage regulation applications.

Q: Are both substitute parts available in the same package?

A: Yes. Both EDZVT2R4.7B and EDZVFHT2R4.7B are supplied in SC-79/SOD-523 surface mount packages, identical to the original DZ2S047M0L. Supplier device packages differ (EMD2 designation for Rohm parts), but physical form factor and PCB footprint compatibility are maintained.

Q: What is the difference between EDZVT2R4.7B and EDZVFHT2R4.7B?

A: The EDZVFHT2R4.7B includes AEC-Q101 automotive qualification and specifies maximum junction temperature of 150°C, indicating automotive-grade reliability. The EDZVT2R4.7B operates across -55°C to 150°C temperature range without automotive qualification. Both maintain identical 4.7 V / 4.65 V nominal voltages, 150 mW power rating, and reverse leakage specifications. Selection depends on application requirements for automotive compliance.

Q: Are there impedance differences between the original and substitute parts?

A: Yes. The DZ2S047M0L specifies maximum impedance (Zzt) of 80 Ohms, while both Rohm substitutes specify 100 Ohms maximum. This 20 Ohm difference represents approximately 25% higher impedance in the substitute parts. For applications requiring precise impedance matching, this parameter should be evaluated against circuit design specifications.

Q: Do the substitute parts meet RoHS compliance requirements?

A: Yes. Both EDZVT2R4.7B and EDZVFHT2R4.7B are ROHS3 compliant with REACH unaffected status, exceeding the RoHS compliance of the original DZ2S047M0L. These certifications confirm suitability for regulated markets and environmental compliance requirements.

Q: What inventory availability exists for substitute parts?

A: EDZVT2R4.7B has 18,178 units in stock, providing substantial availability for production requirements. EDZVFHT2R4.7B has 1,065 units in stock. Both parts are active products with confirmed ongoing supply, contrasting with the discontinued status of the original DZ2S047M0L.
