DZ2W07500L Equivalent & Substitute Parts

Part Overview

The DZ2W07500L is a Zener diode manufactured by Panasonic Electronic Components, rated at 7.5 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 discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active product lines. Substitute parts must maintain compatibility across voltage rating, power rating, package type, and mounting configuration to ensure direct replacement capability in existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DZ2W07500L are identified based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Zener voltage rating within acceptable circuit tolerance
• Maximum power dissipation of 1 W
• Surface mount package type SOD-123F
• Moisture sensitivity level MSL 1
• RoHS compliance status

Substitute Identification Logic:

The KDZVTFTR7.5B and KDZVTR7.5B from Rohm Semiconductor are classified as substitutes based on matching package configuration (SOD-123F), identical power rating (1 W), and compatible mounting type (surface mount). Both parts operate at 7.95 V nominal Zener voltage, which represents a 6% deviation from the 7.5 V specification of the DZ2W07500L. This voltage differential falls within typical circuit design tolerances for Zener diode applications where voltage regulation margins accommodate ±5% to ±10% variations. Both substitute parts maintain MSL 1 rating and RoHS3 compliance, ensuring environmental and regulatory compatibility.

Engineering Selection Recommendations

KDZVTFTR7.5B Selection Criteria:

The KDZVTFTR7.5B is an active product from Rohm Semiconductor with AEC-Q101 automotive qualification. This part is suitable for applications requiring automotive-grade reliability and traceability. The automotive qualification provides additional process control and quality assurance documentation. Inventory availability is 4040 pieces. This part is appropriate for designs where automotive compliance or enhanced quality documentation is a requirement.

KDZVTR7.5B Selection Criteria:

The KDZVTR7.5B is an active product from Rohm Semiconductor with significantly higher inventory availability at 24,300 pieces. This part lacks automotive qualification but maintains ROHS3 compliance and MSL 1 rating. The KDZVTR7.5B is suitable for general industrial and consumer applications where automotive qualification is not required. The higher inventory level provides superior supply chain availability.

Voltage Consideration:

Both substitute parts operate at 7.95 V nominal Zener voltage compared to the 7.5 V specification of the DZ2W07500L. The 0.45 V differential (6% increase) is within standard circuit design margins for Zener diode voltage regulation applications. Circuit designs utilizing the DZ2W07500L typically incorporate voltage regulation tolerances that accommodate this variance. Selection between substitutes should be based on application-specific requirements for automotive qualification and inventory availability rather than voltage differential.

Frequently Asked Questions (FAQ)

Q: Can KDZVTFTR7.5B and KDZVTR7.5B be used interchangeably with DZ2W07500L?

A: Both Rohm parts are functionally equivalent substitutes for the DZ2W07500L in applications where the 7.95 V Zener voltage is acceptable within circuit design tolerances. Both parts share identical package configuration (SOD-123F), power rating (1 W), and mounting type (surface mount). Selection between the two Rohm alternatives depends on automotive qualification requirements and inventory availability.

Q: What is the significance of the voltage difference between 7.5 V and 7.95 V?

A: The 0.45 V difference represents a 6% increase in nominal Zener voltage. Zener diode applications typically incorporate voltage regulation margins that accommodate ±5% to ±10% variations in nominal voltage. Circuit designs using the DZ2W07500L are engineered to function within these tolerance bands. The substitute parts operate within acceptable design parameters for standard voltage regulation applications.

Q: Does the higher reverse leakage current in the Rohm parts affect substitution?

A: The KDZVTFTR7.5B and KDZVTR7.5B specify 20 µA reverse leakage at 4 V compared to 10 µA at 3 V for the DZ2W07500L. Reverse leakage current in Zener diodes is a secondary parameter that does not typically limit substitution in voltage regulation circuits. The specified leakage values for both substitute parts are within acceptable ranges for standard Zener diode applications.

Q: What is the difference between KDZVTFTR7.5B and KDZVTR7.5B?

A: The KDZVTFTR7.5B includes AEC-Q101 automotive qualification and operates at a maximum junction temperature of 150°C. The KDZVTR7.5B is a general-purpose variant without automotive qualification. Both parts are electrically equivalent with identical voltage, power, and package specifications. Selection depends on whether automotive qualification documentation is required for the application.

Q: Are the substitute parts RoHS compliant?

A: Both KDZVTFTR7.5B and KDZVTR7.5B are ROHS3 compliant, meeting current RoHS directive requirements. The original DZ2W07500L is RoHS compliant. All three parts satisfy RoHS compliance requirements for applications subject to RoHS regulations.

Q: What is the MSL rating and why does it matter?

A: All three parts carry MSL 1 (Unlimited) rating, indicating unlimited shelf life without moisture absorption concerns. This classification means the parts do not require special moisture control during storage or handling. MSL 1 rating ensures compatibility across supply chain logistics without additional environmental controls.
