DZ2J027M0L Zener Diode Equivalent & Substitute Parts

Part Overview

The DZ2J027M0L is a 2.7 V, 200 mW Zener diode manufactured by Panasonic Electronic Components in the SC-90/SOD-323F surface mount package. This component is designed for voltage regulation and protection applications requiring a nominal Zener voltage of 2.7 V with ±2.5% tolerance. The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active product lines. Substitute parts must maintain electrical performance across voltage regulation, power dissipation, and impedance specifications while accommodating the surface mount package format.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DZ2J027M0L is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Matching Parameters:

• Zener voltage: 2.7 V nominal
• Maximum power dissipation: 200 mW
• Maximum impedance: 110 Ohms
• Package format: SC-90/SOD-323F surface mount
• Mounting type: Surface mount
• Moisture sensitivity: MSL 1 (Unlimited)

Acceptable Variation Parameters:

• Zener voltage tolerance: Substitute parts may exceed the ±2.5% specification of the original part, provided the nominal voltage remains 2.7 V
• Reverse leakage current: Substitute parts with lower reverse leakage (100 µA @ 1 V versus 120 µA @ 1 V) are acceptable as this represents improved performance
• Operating temperature range: Extended or different temperature ranges are acceptable provided the substitute operates within the application's thermal requirements
• Compliance certifications: Substitute parts with enhanced compliance status (ROHS3, AEC-Q101, REACH Unaffected) are acceptable

The identified substitute parts UDZVTE-172.7B and UDZVFHTE-172.7B from Rohm Semiconductor meet all critical matching parameters and are currently in active production status.

Parameter Comparison

Engineering Selection Recommendations

UDZVTE-172.7B (Rohm Semiconductor) is the primary substitute for the DZ2J027M0L. This part maintains identical electrical specifications across all critical parameters: 2.7 V nominal Zener voltage, 200 mW maximum power dissipation, 110 Ohms maximum impedance, and SC-90/SOD-323F package format. The UDZVTE-172.7B is in active production status with ROHS3 compliance and REACH Unaffected designation. Operating temperature range of -55°C to 150°C provides extended thermal coverage. Reverse leakage current of 100 µA @ 1 V represents improved performance relative to the original specification.

UDZVFHTE-172.7B (Rohm Semiconductor) is an alternative substitute with automotive-grade qualification (AEC-Q101) and maximum operating temperature of 150°C. This part is suitable for applications requiring automotive-level reliability and traceability. The ±4.07% Zener voltage tolerance is wider than the original ±2.5% specification but remains within acceptable limits for most voltage regulation applications. Reverse leakage current of 100 µA @ 1 V matches the UDZVTE-172.7B performance.

Both substitute parts are available in active inventory and support equivalent packaging formats (Cut Tape and Digi-Reel options). Selection between UDZVTE-172.7B and UDZVFHTE-172.7B depends on application-specific requirements for automotive qualification and operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can UDZVTE-172.7B or UDZVFHTE-172.7B be used as direct replacements for DZ2J027M0L in existing designs?

A: Yes. Both Rohm parts maintain identical nominal Zener voltage (2.7 V), maximum power dissipation (200 mW), impedance (110 Ohms), and package format (SC-90/SOD-323F). The electrical performance is equivalent for voltage regulation and protection applications. No circuit modifications are required.

Q: What is the difference between UDZVTE-172.7B and UDZVFHTE-172.7B?

A: The primary differences are Zener voltage tolerance and automotive qualification. UDZVTE-172.7B has unspecified tolerance and operates from -55°C to 150°C. UDZVFHTE-172.7B has ±4.07% tolerance, automotive-grade qualification (AEC-Q101), and maximum operating temperature of 150°C. Both parts have identical power dissipation, impedance, and reverse leakage specifications.

Q: Is the wider tolerance of UDZVFHTE-172.7B (±4.07% versus ±2.5%) acceptable?

A: Tolerance acceptability depends on application requirements. For voltage regulation circuits with tight voltage specifications, the ±2.5% tolerance of the original part may be preferred. For general protection applications, the ±4.07% tolerance of UDZVFHTE-172.7B is acceptable. Circuit design margins should be verified against the application's voltage regulation requirements.

Q: Are the substitute parts available in the same packaging formats as the original?

A: Yes. Both UDZVTE-172.7B and UDZVFHTE-172.7B are supplied in Cut Tape (CT) and Digi-Reel packaging formats, matching the original part's surface mount delivery options. The SC-90/SOD-323F package format is identical across all three parts.

Q: What is the significance of the lower reverse leakage current in the substitute parts?

A: The substitute parts specify 100 µA @ 1 V reverse leakage current compared to 120 µA @ 1 V for the original part. Lower reverse leakage represents improved performance and does not create compatibility issues. This characteristic is beneficial for applications sensitive to leakage current.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both UDZVTE-172.7B and UDZVFHTE-172.7B are ROHS3 compliant and REACH Unaffected, exceeding the RoHS compliance status of the original DZ2J027M0L part.

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

A: UDZVFHTE-172.7B is qualified to AEC-Q101 automotive standards and is the appropriate selection for automotive applications requiring traceability and reliability certification. UDZVTE-172.7B is suitable for general industrial and consumer applications.
