Key Parameters

Substitute Part Grouping Explanation

Substitution of the DZ2W02700L is determined by the following critical parameters:

Primary Substitution Criteria:

• Nominal Zener voltage within acceptable circuit tolerance
• Maximum power rating equal to or greater than 1 W
• Reverse leakage current specification at rated voltage
• Surface mount package compatibility (SOD-123F)
• Operating temperature range coverage
• RoHS compliance status

The KDZVTR2.7B from Rohm Semiconductor qualifies as a substitute based on matching power rating (1 W), identical package type (SOD-123F), equivalent reverse leakage specification (200 µA @ 1 V), and surface mount configuration. The nominal Zener voltage of 2.9 V represents a 7.4% deviation from the DZ2W02700L specification, which falls within acceptable substitution parameters for general voltage regulation applications where the circuit design accommodates this voltage differential.

Engineering Selection Recommendations

DZ2W02700L (Panasonic Electronic Components)

The original part is discontinued at DiGi Electronics. Existing inventory of 4,550 pieces is available through current stock channels. This component is RoHS Compliant and carries MSL 1 rating, indicating no moisture sensitivity constraints during storage and handling.

KDZVTR2.7B (Rohm Semiconductor)

This substitute is currently active in production with 9,712 pieces in stock. The part meets ROHS3 Compliant standards and maintains MSL 1 classification. The KDZVTR2.7B operates at a maximum junction temperature of 150°C, providing extended thermal performance compared to the DZ2W02700L's 85°C maximum operating temperature. Both components share identical package geometry (SOD-123F), reverse leakage characteristics, and power rating, enabling direct mechanical and electrical substitution in surface mount applications.

Selection between these parts depends on procurement availability, supply chain continuity, and thermal operating environment requirements. The KDZVTR2.7B offers superior temperature performance and active production status, while the DZ2W02700L remains available through existing inventory channels.

Frequently Asked Questions (FAQ)

Q: Can the KDZVTR2.7B directly replace the DZ2W02700L in existing designs?

A: The KDZVTR2.7B is mechanically and electrically compatible for direct substitution in SOD-123F surface mount applications. Both components share identical package dimensions, power ratings, and reverse leakage specifications. The 0.2 V difference in nominal Zener voltage (2.7 V vs. 2.9 V) must be evaluated within the specific circuit application to confirm voltage regulation requirements are maintained.

Q: What is the significance of the tolerance difference between these parts?

A: The DZ2W02700L specifies ±5% tolerance, while the KDZVTR2.7B specifies ±7.41% tolerance. This difference affects the voltage regulation accuracy in precision applications. Circuit designs requiring tighter voltage control should account for the wider tolerance band of the KDZVTR2.7B during component selection.

Q: Are both parts suitable for high-temperature applications?

A: The KDZVTR2.7B operates at a maximum junction temperature of 150°C, compared to the DZ2W02700L's 85°C maximum operating temperature. For applications requiring extended thermal performance, the KDZVTR2.7B provides superior temperature capability. Both components maintain MSL 1 classification, indicating no moisture sensitivity limitations.

Q: Do package and mounting considerations differ between these parts?

A: Both the DZ2W02700L and KDZVTR2.7B utilize SOD-123F surface mount packaging. No modifications to PCB layout, footprint design, or reflow soldering profiles are required when substituting between these components. Supplier device packages differ (Mini2-F3-B vs. PMDU), but the physical package specification remains identical.

Q: What compliance certifications apply to both parts?

A: The DZ2W02700L is RoHS Compliant. The KDZVTR2.7B is ROHS3 Compliant and REACH Unaffected. Both components carry ECCN EAR99 classification and HTSUS code 8541.10.0050. Both maintain MSL 1 (Unlimited) moisture sensitivity rating.
