MAZ32400ML Equivalent & Substitute Parts

Part Overview

The MAZ32400ML is a Zener diode rated at 24 V nominal voltage with 200 mW maximum power dissipation, manufactured by Panasonic Electronic Components in a Surface Mount Mini3-G1 package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The part operates with ±6% voltage tolerance and is suitable for voltage regulation and protection applications in surface mount assemblies.

Substitute Part Grouping Explanation

Substitution of the MAZ32400ML is based on electrical and mechanical parameter equivalence within the Zener diode category. The critical parameters determining substitutability are:

Zener Voltage (Vz): Must be 24 V nominal
Voltage Tolerance: Must be ±6%
Impedance (Zzt): Must be 70 Ohms maximum
Reverse Leakage Current: Must be 50 nA at specified reverse voltage
Forward Voltage (Vf): Must be 900 mV maximum at 10 mA
Package / Case: Must be TO-236-3, SC-59, or SOT-23-3 compatible
Mounting Type: Must be Surface Mount
Moisture Sensitivity Level: Must be MSL 1 (Unlimited)

The substitute parts BZX84C24LT1G and SZBZX84C24LT1G meet all these electrical and mechanical requirements. Both are manufactured by onsemi and feature identical nominal voltage, tolerance, impedance, reverse leakage, and forward voltage specifications. The primary difference is packaging format (Cut Tape & Digi-Reel® versus Tape & Reel) and automotive qualification for the SZBZX84C24LT1G variant.

Engineering Selection Recommendations

BZX84C24LT1G is the primary substitute for general-purpose applications. This part is active in production, ROHS3 compliant, and electrically equivalent to the MAZ32400ML. The 225 mW power rating provides 12.5% additional thermal margin compared to the original 200 mW specification. This part is available in Cut Tape & Digi-Reel® packaging, matching the original packaging format.

SZBZX84C24LT1G is the recommended substitute for automotive and mission-critical applications. This variant carries AEC-Q101 automotive qualification and REACH compliance certification in addition to ROHS3 compliance. It is supplied in Tape & Reel format and provides identical electrical performance to BZX84C24LT1G. Selection of this variant is appropriate when automotive-grade reliability and traceability are required.

Both substitute parts are currently in active production with substantial inventory availability, ensuring supply chain continuity for the obsolete MAZ32400ML.

Frequently Asked Questions (FAQ)

Q: Can BZX84C24LT1G and SZBZX84C24LT1G be used interchangeably with MAZ32400ML?

A: Yes. Both parts meet all electrical and mechanical specifications of the MAZ32400ML. They share identical nominal voltage (24 V), tolerance (±6%), impedance (70 Ohms), reverse leakage current (50 nA), forward voltage (900 mV @ 10 mA), and package compatibility (TO-236-3, SC-59, SOT-23-3). The substitute parts have higher power ratings (225 mW versus 200 mW), which provides additional thermal margin without affecting circuit operation.

Q: What is the difference between BZX84C24LT1G and SZBZX84C24LT1G?

A: Both parts are electrically identical. The primary differences are packaging format and automotive qualification. BZX84C24LT1G is supplied in Cut Tape & Digi-Reel® format, while SZBZX84C24LT1G is supplied in Tape & Reel format. SZBZX84C24LT1G carries AEC-Q101 automotive qualification, making it suitable for automotive applications requiring formal qualification documentation.

Q: Are the substitute parts compatible with the original TO-236-3 package footprint?

A: Yes. Both BZX84C24LT1G and SZBZX84C24LT1G use the SOT-23-3 package, which is equivalent to TO-236-3 and SC-59. The physical footprint and pin configuration are identical, allowing direct board-level substitution without layout modifications.

Q: What is the inventory status of these substitute parts?

A: BZX84C24LT1G has 17,200 pieces in stock. SZBZX84C24LT1G has 9,100 pieces in stock. Both parts are in active production with established supply chains.
