DZ2W02400L Equivalent & Substitute Parts

Part Overview

The DZ2W02400L is a 2.4 V, 1 W Zener diode manufactured by Panasonic Electronic Components in a Surface Mount SOD-123F package. This component is designed for voltage regulation and protection applications requiring a nominal Zener voltage of 2.4 V with ±5% tolerance. The part is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active product lines. Substitute parts must maintain compatibility with the SOD-123F package footprint and deliver equivalent electrical performance within specified operating parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DZ2W02400L are qualified based on the following critical parameters:

Electrical Compatibility Criteria:

• Zener voltage nominal value within acceptable circuit tolerance
• Maximum power dissipation rating of 1 W or greater
• Reverse leakage current specification of 200 µA @ 1 V or lower
• Surface Mount technology with SOD-123F package footprint

Compliance & Availability Criteria:

• Active product status ensuring supply chain continuity
• RoHS compliance for environmental and regulatory alignment
• Moisture Sensitivity Level 1 for standard handling and storage

The identified substitute parts (KDZVTFTR2.4B and KDZVTR2.4B) from Rohm Semiconductor meet these criteria. Both parts operate at 2.55 V nominal Zener voltage, which represents a 4.2% deviation from the 2.4 V specification. This voltage differential falls within typical circuit design tolerances for voltage regulation applications. Both substitutes maintain the 1 W power rating, SOD-123F package format, and equivalent reverse leakage characteristics.

Parameter Comparison

Engineering Selection Recommendations

KDZVTFTR2.4B Selection Criteria: This part is suitable for applications requiring automotive-grade qualification. The AEC-Q101 certification indicates compliance with automotive reliability standards. The Cut Tape & Digi-Reel® packaging provides flexibility for both manual and automated assembly processes. Inventory availability of 2,696 pieces supports production requirements. ROHS3 compliance and REACH Unaffected status satisfy current environmental regulations.

KDZVTR2.4B Selection Criteria: This part is recommended for high-volume production environments. The Tape & Reel (TR) packaging format optimizes automated pick-and-place assembly. Significantly higher inventory availability (18,100 pieces) ensures supply continuity. ROHS3 compliance and REACH Unaffected status align with regulatory requirements. The extended maximum operating temperature of 150°C (TJ) provides thermal margin beyond the original DZ2W02400L specification.

Common Considerations: Both Rohm substitutes operate at 2.55 V nominal Zener voltage, representing a 4.2% increase from the original 2.4 V specification. Circuit designs must accommodate this voltage differential within their tolerance budgets. The ±6.25% tolerance of the Rohm parts is wider than the original ±5% specification. Both parts maintain identical reverse leakage current and power dissipation ratings, ensuring functional equivalence in protection and regulation applications.

Frequently Asked Questions (FAQ)

Q: Can KDZVTFTR2.4B and KDZVTR2.4B be used interchangeably with DZ2W02400L?

A: Both Rohm parts are electrically and mechanically compatible substitutes. The primary difference is packaging format: KDZVTFTR2.4B is supplied in Cut Tape & Digi-Reel®, while KDZVTR2.4B is supplied in Tape & Reel (TR). Selection depends on assembly process requirements. Both parts operate at 2.55 V nominal Zener voltage, which must be evaluated against circuit tolerance specifications.

Q: What is the voltage difference between the original part and the substitutes?

A: The DZ2W02400L operates at 2.4 V nominal, while both Rohm substitutes operate at 2.55 V nominal. This represents a 4.2% increase in Zener voltage. Circuit designs must confirm that this voltage differential does not exceed application tolerance requirements.

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

A: Yes. All three parts use the SOD-123F Surface Mount package, ensuring identical PCB footprint compatibility. No layout modifications are required for substitution.

Q: What are the compliance differences between the original and substitute parts?

A: The original DZ2W02400L is RoHS Compliant. Both Rohm substitutes are ROHS3 Compliant, representing a more recent environmental standard. KDZVTFTR2.4B carries AEC-Q101 automotive qualification, while KDZVTR2.4B does not. Both substitutes are REACH Unaffected.

Q: Which substitute part should be selected for automotive applications?

A: KDZVTFTR2.4B is qualified to AEC-Q101 automotive standards and is the appropriate choice for automotive circuit designs. KDZVTR2.4B is suitable for general industrial and consumer applications.

Q: How do the tolerance specifications compare?

A: The original DZ2W02400L specifies ±5% tolerance, while both Rohm substitutes specify ±6.25% tolerance. This wider tolerance band must be evaluated within circuit design margins to ensure acceptable performance across the full tolerance range.

Q: What is the maximum operating temperature for each part?

A: The DZ2W02400L operates from -40°C to 85°C. Both Rohm substitutes specify a maximum junction temperature (TJ) of 150°C, providing extended thermal capability. Circuit thermal analysis must confirm that actual junction temperatures remain within specified limits.

Q: Are moisture sensitivity levels equivalent?

A: Yes. All three parts specify Moisture Sensitivity Level 1 (Unlimited), indicating identical handling, storage, and reflow requirements. No special moisture control procedures are required beyond standard IPC guidelines.
