DZ2W04700L Equivalent & Substitute Parts

Part Overview

The DZ2W04700L is a Zener diode manufactured by Panasonic Electronic Components, rated at 4.7 V nominal voltage with 1 W maximum power dissipation. This component is designed for surface mount applications in the SOD-123F package. The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active manufacturers. Substitute parts must maintain electrical compatibility across voltage regulation, power handling, and leakage characteristics while supporting the same surface mount package format.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DZ2W04700L is determined by the following critical parameters:

Primary Substitution Criteria:

• Zener voltage nominal rating within the application tolerance band
• Maximum power dissipation of 1 W
• Surface mount package format SOD-123F
• Reverse leakage current specification
• RoHS compliance status

Substitution Logic:

The PZ1AL4V7B_R1_00001 (Panjit International Inc.) provides direct electrical equivalence with identical 4.7 V nominal voltage and ±5% tolerance, matching the original specification exactly. This part qualifies as a primary substitute.

The KDZVTFTR4.7B and KDZVTR4.7B (Rohm Semiconductor) operate at 4.95 V nominal voltage, representing a 5.3% deviation from the 4.7 V specification. These parts remain functionally compatible within typical application tolerance windows for voltage regulation circuits but operate at a higher nominal point.

The KDZVTR4.3B (Rohm Semiconductor) operates at 4.55 V nominal voltage, representing a 3.2% deviation below the 4.7 V specification. This part is suitable for applications where lower voltage regulation is acceptable.

All substitute candidates maintain the 1 W power rating, SOD-123F package format, and surface mount mounting type required for direct board-level replacement.

Engineering Selection Recommendations

Primary Substitute: PZ1AL4V7B_R1_00001 (Panjit International Inc.)

The PZ1AL4V7B_R1_00001 is the optimal substitute for the DZ2W04700L. This part maintains identical electrical specifications: 4.7 V nominal voltage with ±5% tolerance, 1 W maximum power, and SOD-123F package format. The part is currently in active production status with 2,701 units in stock. ROHS3 compliance and REACH unaffected status confirm regulatory alignment. The lower reverse leakage current (10 µA @ 1 V versus 40 µA @ 1 V) represents an improvement in leakage performance. Operating temperature range of -55°C to 150°C provides extended thermal capability.

Secondary Substitutes: KDZVTFTR4.7B and KDZVTR4.7B (Rohm Semiconductor)

Both Rohm parts operate at 4.95 V nominal voltage, representing a 5.3% increase from the 4.7 V specification. These parts are suitable for applications where the higher nominal voltage falls within acceptable circuit tolerance. Both parts carry automotive-grade qualification (AEC-Q101 for KDZVTFTR4.7B) and are in active production with substantial inventory availability (13,485 and 12,236 units respectively). ROHS3 compliance and REACH unaffected status confirm regulatory compliance. Reverse leakage current of 20 µA @ 1 V is lower than the original specification.

Tertiary Substitute: KDZVTR4.3B (Rohm Semiconductor)

The KDZVTR4.3B operates at 4.55 V nominal voltage, representing a 3.2% decrease from the 4.7 V specification. This part is suitable for applications where lower voltage regulation is acceptable within circuit design margins. The part is in active production with 6,695 units in stock. ROHS3 compliance and REACH unaffected status confirm regulatory alignment. Reverse leakage current of 20 µA @ 1 V is lower than the original specification.

All substitute parts maintain the SOD-123F package format and 1 W power rating, enabling direct board-level replacement without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the PZ1AL4V7B_R1_00001 be used as a direct replacement for the DZ2W04700L?

A: Yes. The PZ1AL4V7B_R1_00001 maintains identical nominal voltage (4.7 V), tolerance (±5%), power rating (1 W), and package format (SOD-123F). The part is currently in active production and meets all regulatory requirements.

Q: What is the voltage difference between the DZ2W04700L and the Rohm KDZVTFTR4.7B?

A: The KDZVTFTR4.7B operates at 4.95 V nominal voltage compared to the 4.7 V specification of the DZ2W04700L, representing a 5.3% increase. This voltage difference must be evaluated against circuit design tolerance requirements.

Q: Are all substitute parts in the same package format?

A: Yes. All substitute parts use the SOD-123F package format, enabling direct board-level replacement without PCB layout modifications.

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

A: The DZ2W04700L specifies 40 µA @ 1 V reverse leakage. The PZ1AL4V7B_R1_00001 specifies 10 µA @ 1 V, while all Rohm parts specify 20 µA @ 1 V. Lower leakage current values represent improved performance characteristics.

Q: Do all substitute parts meet RoHS compliance requirements?

A: Yes. All substitute parts carry ROHS3 compliance status, meeting current regulatory requirements. The original DZ2W04700L carries RoHS Compliant status.

Q: Which substitute part has automotive qualification?

A: The KDZVTFTR4.7B carries AEC-Q101 automotive qualification and is rated for 150°C operating temperature, making it suitable for automotive applications.

Q: Can the KDZVTR4.3B be used in place of the DZ2W04700L?

A: The KDZVTR4.3B operates at 4.55 V nominal voltage, which is 3.2% below the 4.7 V specification. Substitution is valid only if circuit design tolerances accommodate the lower voltage regulation point.

Q: What is the inventory status of substitute parts?

A: PZ1AL4V7B_R1_00001 has 2,701 units in stock. KDZVTFTR4.7B has 13,485 units in stock. KDZVTR4.7B has 12,236 units in stock. KDZVTR4.3B has 6,695 units in stock.
