DZ2J05600L Equivalent & Substitute Parts

Part Overview

The DZ2J05600L is a Zener diode manufactured by Panasonic Electronic Components, rated at 5.6 V nominal voltage with 200 mW maximum power dissipation in a surface mount SMini2-F5-B package. This component is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active manufacturers. Substitute parts must maintain electrical compatibility across voltage regulation, power handling, and thermal characteristics while accommodating available packaging options.

Substitute Part Grouping Explanation

Substitution of the DZ2J05600L is determined by the following critical parameters:

Primary Electrical Criteria:

Zener voltage nominal rating of 5.6 V or within tolerance band
Maximum power dissipation of 200 mW or greater
Surface mount mounting type
Package compatibility with SC-90 or SOD-323F footprints

Secondary Electrical Criteria:

Impedance characteristics
Reverse leakage current specifications

Engineering Selection Recommendations

Category 1: Direct Electrical and Package Equivalents (200 mW, SC-90/SOD-323F)

UDZSTE-175.6B, UDZVTE-175.6B, and UDZVFHTE-175.6B are functionally equivalent to the DZ2J05600L in power rating and package configuration. All three are manufactured by Rohm Semiconductor and maintain active product status.

UDZSTE-175.6B provides tighter voltage tolerance (±2%) compared to the original ±5% specification, with identical 200 mW power rating and SC-90/SOD-323F package. This part is suitable for applications requiring improved voltage regulation accuracy.

UDZVTE-175.6B offers the same electrical specifications as UDZSTE-175.6B without specified tolerance, maintaining 200 mW power and SC-90/SOD-323F package compatibility.

UDZVFHTE-175.6B is qualified to AEC-Q101 automotive standards with 150°C maximum junction temperature rating. This part is appropriate for automotive and high-reliability applications requiring formal qualification documentation.

Category 2: Higher Power Alternatives (500 mW)

TFZVTR5.6B and YFZVFHTR5.6B provide 500 mW power dissipation capability in TUMD2M surface mount packages. These parts accommodate applications requiring increased thermal headroom or higher current handling.

TFZVTR5.6B is a standard industrial-grade 500 mW device with operating temperature range of -55°C to 150°C.

YFZVFHTR5.6B is AEC-Q101 qualified for automotive applications with 150°C maximum junction temperature rating and ±2.5% voltage tolerance.

Compliance and Availability:

All substitute parts maintain RoHS3 compliance and MSL 1 (unlimited) moisture sensitivity rating. All identified substitutes are currently active products with confirmed inventory availability, ensuring long-term supply continuity.

Frequently Asked Questions (FAQ)

Q: Can TFZVTR5.6B or YFZVFHTR5.6B be used as direct replacements for DZ2J05600L?

A: These 500 mW parts are electrically compatible with the 5.6 V zener voltage specification. However, they use TUMD2M packages (2-SMD, Flat Lead) rather than the original SC-90/SOD-323F package. PCB layout modifications are required for package substitution. The higher power rating does not create functional incompatibility in circuits designed for 200 mW operation.

Q: What is the difference between UDZSTE-175.6B and UDZVTE-175.6B?

A: Both parts share identical electrical specifications (5.6 V, 200 mW, SC-90/SOD-323F package) and operating temperature range (-55°C to 150°C). UDZSTE-175.6B specifies ±2% voltage tolerance, while UDZVTE-175.6B does not specify tolerance. UDZSTE-175.6B is preferred for applications requiring documented voltage accuracy.

Q: Are automotive-qualified parts (UDZVFHTE-175.6B, YFZVFHTR5.6B) suitable for non-automotive applications?

A: Yes. AEC-Q101 qualification indicates compliance with automotive reliability standards and does not restrict use in other applications. These parts are suitable for any application requiring the specified electrical characteristics and thermal performance.

Q: What is the impact of impedance differences between substitute parts?

A: The DZ2J05600L specifies 40 Ohms maximum impedance. UDZSTE-175.6B, UDZVTE-175.6B, and UDZVFHTE-175.6B specify 60 Ohms maximum impedance. TFZVTR5.6B and YFZVFHTR5.6B specify 13 Ohms maximum impedance. Lower impedance provides better high-frequency performance and faster transient response. Higher impedance may affect circuit performance in applications with stringent noise or transient requirements. Circuit validation is necessary when impedance specifications differ significantly.

Q: Can parts with different voltage ratings (5.59 V, 5.6 V, 5.61 V) be interchanged?

A: These voltage variations fall within acceptable tolerance bands for 5.6 V zener applications. YFZVFHTR5.6B (5.59 V) and UDZVFHTE-175.6B (5.61 V) represent ±1.8% and ±1.8% deviations respectively from the 5.6 V nominal. Interchangeability depends on circuit voltage regulation requirements. Applications with tight voltage specifications should verify compatibility with the specific substitute part voltage rating.

Q: What packaging considerations apply when selecting substitutes?

A: The DZ2J05600L uses SC-90/SOD-323F package. UDZSTE-175.6B, UDZVTE-175.6B, and UDZVFHTE-175.6B maintain this package footprint and are direct PCB replacements. TFZVTR5.6B and YFZVFHTR5.6B use TUMD2M packages (2-SMD, Flat Lead), requiring PCB layout redesign. Package selection depends on available PCB space and manufacturing capabilities.

Q: How do reverse leakage current specifications affect part selection?

A: The DZ2J05600L specifies 500 nA reverse leakage at 2.5 V. Substitute parts specify 1 µA (UDZSTE-175.6B, UDZVTE-175.6B, UDZVFHTE-175.6B) or 5 µA (TFZVTR5.6B, YFZVFHTR5.6B). Higher leakage current increases standby power consumption and may affect precision voltage reference applications. Standard voltage regulation circuits are not affected by these leakage variations.
