DZ2W08200L Equivalent & Substitute Parts

Part Overview

The DZ2W08200L is a Zener diode manufactured by Panasonic Electronic Components, rated at 8.2 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 to maintain design continuity and supply chain reliability.

Substitute Part Grouping Explanation

Substitution of the DZ2W08200L is determined by the following critical parameters:

Primary Substitution Criteria:

Zener voltage rating within acceptable circuit tolerance
Maximum power dissipation of 1 W
Surface mount package compatibility (SOD-123F)
Reverse leakage current characteristics
RoHS compliance status

The three identified substitute parts from Rohm Semiconductor (KDZVTR8.2B, KDZVTR7.5B, and KDZVTFTR8.2B) share the same package type and power rating. Voltage variations exist across the substitute options, ranging from 7.95 V to 8.75 V nominal, which fall within acceptable operating ranges for circuits designed around the 8.2 V specification. All substitutes maintain surface mount compatibility and RoHS compliance.

Engineering Selection Recommendations

KDZVTR8.2B and KDZVTFTR8.2B provide the closest nominal voltage alignment to the original DZ2W08200L at 8.75 V. Both parts are manufactured by Rohm Semiconductor with active product status, ensuring ongoing availability and supply chain stability. KDZVTFTR8.2B carries AEC-Q101 automotive qualification, suitable for applications requiring automotive-grade reliability. Both maintain ROHS3 compliance and identical moisture sensitivity ratings.

KDZVTR7.5B offers a lower nominal voltage of 7.95 V and represents an alternative for circuits where reduced voltage regulation is acceptable. This part maintains active status and full compliance with environmental standards.

All three substitute parts are available in higher inventory quantities compared to the discontinued DZ2W08200L, supporting production continuity. The SOD-123F package compatibility ensures direct footprint replacement without PCB redesign.

Frequently Asked Questions (FAQ)

Q: Can KDZVTR8.2B directly replace DZ2W08200L in existing designs?

A: Yes. Both parts share identical SOD-123F package geometry, 1 W power rating, and surface mount configuration. The nominal voltage difference of 0.55 V (8.75 V vs. 8.2 V) falls within typical circuit tolerance margins for Zener diode applications. Circuit validation is required to confirm voltage regulation performance within specific application parameters.

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

A: The DZ2W08200L specifies ±5% tolerance. KDZVTFTR8.2B specifies ±6.71% tolerance. KDZVTR8.2B and KDZVTR7.5B do not provide tolerance specifications in the available data. Tolerance variations affect voltage regulation precision and should be evaluated against circuit requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. All three substitute parts meet ROHS3 compliance, exceeding the RoHS compliance status of the original DZ2W08200L. This ensures compatibility with environmental and regulatory requirements.

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

A: The DZ2W08200L specifies 10 µA @ 4 V. All three substitute parts specify 20 µA at their respective test voltages (4 V or 5 V). Higher leakage current may affect circuit performance in applications with stringent leakage requirements.

Q: Does KDZVTFTR8.2B offer additional qualifications?

A: Yes. KDZVTFTR8.2B carries AEC-Q101 automotive qualification and is designated as an automotive-grade component. This qualification is not specified for the other substitute options or the original part.

Q: Are there inventory differences between substitute options?

A: Yes. KDZVTR7.5B has the highest inventory at 24,300 pieces. KDZVTFTR8.2B has 6,917 pieces, and KDZVTR8.2B has 6,100 pieces. The original DZ2W08200L has 2,100 pieces remaining but is discontinued.

Q: Can KDZVTR7.5B be used as a substitute despite lower voltage?

A: KDZVTR7.5B at 7.95 V nominal represents a 2.9% reduction from the 8.2 V specification. Substitution depends on circuit tolerance for lower regulation voltage. Applications requiring precise 8.2 V operation should use KDZVTR8.2B or KDZVTFTR8.2B instead.
