MAZ31300ML Equivalent & Substitute Parts

Part Overview

The MAZ31300ML is a Zener diode manufactured by Panasonic Electronic Components, rated at 13 V nominal with 200 mW maximum power dissipation in a Surface Mount Mini3-G1 package. This component is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement continuity. Substitute parts must maintain electrical equivalence across voltage regulation, power handling, and impedance characteristics while accommodating modern packaging and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAZ31300ML is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Equivalence Parameters:

• Voltage - Zener (Nom): 13 V
• Tolerance: ±6%
• Impedance (Max): 30 Ohms
• Current - Reverse Leakage @ Vr: 100 nA
• Voltage - Forward (Vf) (Max) @ If: 900 mV @ 10 mA
• Package / Case: TO-236-3, SC-59, SOT-23-3
• Mounting Type: Surface Mount

Acceptable Variation:

• Power - Max: Substitute parts rated at 225 mW exceed the original 200 mW specification, providing enhanced thermal margin while maintaining functional compatibility within the same package envelope.

All identified substitute parts meet or exceed the electrical performance requirements of the MAZ31300ML while maintaining identical package geometry and mounting characteristics.

Parameter Comparison

Engineering Selection Recommendations

BZX84C13LT1G (onsemi): This part provides direct electrical equivalence with the MAZ31300ML across all critical parameters. The 225 mW power rating represents a 12.5% increase over the original specification, offering improved thermal performance within the identical SOT-23-3 package. The part is in active production status with ROHS3 compliance, supporting modern supply chain requirements. Operating temperature range of -65°C to 150°C is specified, providing defined thermal boundaries for circuit design.

SZBZX84C13LT1G (onsemi): This automotive-grade variant maintains identical electrical specifications to BZX84C13LT1G while incorporating AEC-Q101 qualification. Selection of this part is appropriate for applications requiring automotive-level reliability and traceability. ROHS3 compliance and active production status ensure long-term availability.

SZBZX84C13LT3G (onsemi): This part is functionally equivalent to SZBZX84C13LT1G, differing only in manufacturing date code designation (LT3G vs. LT1G). Both automotive-grade variants meet identical electrical and compliance requirements. Selection between LT1G and LT3G variants is determined by procurement and inventory management considerations rather than technical performance.

All three substitute parts are in active production, ensuring sustained availability and supply chain stability compared to the obsolete MAZ31300ML.

Frequently Asked Questions (FAQ)

Q: Can BZX84C13LT1G directly replace MAZ31300ML in existing designs?

A: Yes. BZX84C13LT1G meets all electrical equivalence criteria: 13 V nominal voltage, ±6% tolerance, 30 Ohms maximum impedance, 100 nA reverse leakage, and 900 mV forward voltage. Both components use identical TO-236-3 / SOT-23-3 package geometry and Surface Mount mounting type. The 225 mW power rating of BZX84C13LT1G exceeds the 200 mW specification of MAZ31300ML, providing enhanced thermal margin.

Q: What is the difference between BZX84C13LT1G and SZBZX84C13LT1G?

A: Both parts share identical electrical specifications and package geometry. SZBZX84C13LT1G is qualified to AEC-Q101 automotive standards, making it suitable for automotive applications requiring enhanced reliability documentation and traceability. BZX84C13LT1G is the standard industrial-grade equivalent. Selection depends on application requirements rather than electrical performance.

Q: Are SZBZX84C13LT1G and SZBZX84C13LT3G interchangeable?

A: Yes. Both parts are automotive-grade variants with identical electrical specifications and AEC-Q101 qualification. The designation difference (LT1G vs. LT3G) reflects manufacturing date code assignment and does not affect electrical performance or functional compatibility.

Q: Does the increased power rating of substitute parts affect circuit design?

A: No. The 225 mW rating of substitute parts represents a specification increase relative to the 200 mW MAZ31300ML. Circuits designed for 200 mW operation remain within the thermal and electrical limits of 225 mW-rated components. The higher rating provides additional thermal margin without requiring design modification.

Q: Are all substitute parts RoHS compliant?

A: Yes. All three substitute parts (BZX84C13LT1G, SZBZX84C13LT1G, SZBZX84C13LT3G) are ROHS3 compliant. The original MAZ31300ML is RoHS non-compliant. Substitution with any of these parts satisfies modern RoHS compliance requirements.

Q: What is the operating temperature range for substitute parts?

A: All substitute parts operate across -65°C to 150°C (TJ). The original MAZ31300ML does not specify an operating temperature range. The defined range of substitute parts provides explicit thermal boundaries for circuit design and reliability analysis.

Q: Are substitute parts available in the same packaging format?

A: Yes. All substitute parts are supplied in Tape & Reel (TR) packaging, standard for high-volume surface mount assembly. The physical package geometry (TO-236-3 / SOT-23-3) is identical across all parts, ensuring compatibility with existing PCB layouts and pick-and-place equipment.
