Substitute Part Grouping Explanation

Substitution of the MM5Z16VT5G is determined by electrical parameter equivalence and mechanical compatibility. The following criteria establish valid substitution:

Electrical Parameters (Must Match):

• Voltage - Zener (Nom): 16.2 V
• Tolerance: ±5.56%
• Power - Max: 500 mW
• Impedance (Max): 40 Ohms
• Current - Reverse Leakage @ Vr: 50 nA @ 11.2 V
• Voltage - Forward (Max) @ If: 900 mV @ 10 mA
• Operating Temperature Range: -65°C to 150°C (TJ)

Mechanical Parameters (Must Match):

• Package / Case: SC-79, SOD-523
• Mounting Type: Surface Mount
• Supplier Device Package: SOD-523

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The SZMM5Z16VT5G meets all electrical and mechanical requirements for direct substitution. Packaging format differences (Tape & Reel versus Cut Tape & Digi-Reel) do not affect electrical performance or board-level compatibility.

Parameter Comparison

Engineering Selection Recommendations

The SZMM5Z16VT5G is a direct electrical and mechanical equivalent to the MM5Z16VT5G. Both components are active-status products manufactured by onsemi with identical electrical specifications, operating temperature ranges, and package configurations.

Selection Basis:

The SZMM5Z16VT5G carries AEC-Q101 automotive qualification, which the MM5Z16VT5G does not specify. This additional qualification does not restrict its use in non-automotive applications and represents equivalent or superior reliability characteristics.

Both parts comply with ROHS3, maintain MSL 1 (Unlimited) moisture sensitivity, and carry REACH Unaffected status. Packaging format differences (Tape & Reel versus Cut Tape & Digi-Reel) are procurement and handling considerations that do not affect electrical performance or circuit-level compatibility.

Component selection between these parts is determined by supply chain availability, packaging requirements, and procurement specifications rather than electrical or mechanical constraints.

Frequently Asked Questions (FAQ)

Q: Can SZMM5Z16VT5G replace MM5Z16VT5G in existing designs?

A: Yes. The SZMM5Z16VT5G meets all electrical and mechanical specifications of the MM5Z16VT5G. Zener voltage, power rating, impedance, leakage current, forward voltage, operating temperature range, and package configuration are identical. No circuit redesign or board layout modification is required.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging?

A: Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® are packaging and delivery formats that affect component handling and assembly processes. Both formats contain the same component in the same SOD-523 package. The choice between formats depends on manufacturing equipment compatibility and procurement workflow, not electrical performance.

Q: Does the AEC-Q101 qualification on SZMM5Z16VT5G affect its use in non-automotive applications?

A: No. AEC-Q101 is an automotive industry qualification standard. Components meeting this standard are suitable for all applications, including non-automotive use. The qualification indicates additional reliability testing and does not restrict application scope.

Q: Are the electrical parameters identical between MM5Z16VT5G and SZMM5Z16VT5G?

A: Yes. Both components have identical Zener voltage (16.2 V), tolerance (±5.56%), power rating (500 mW), impedance (40 Ohms maximum), reverse leakage current (50 nA @ 11.2 V), forward voltage (900 mV @ 10 mA), and operating temperature range (-65°C to 150°C).

Q: Are both parts RoHS compliant?

A: Yes. Both MM5Z16VT5G and SZMM5Z16VT5G are ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can these parts be used interchangeably on the same printed circuit board?

A: Yes. Both components use the identical SOD-523 surface mount package (SC-79). Footprint, pad layout, and soldering requirements are identical. No PCB redesign is necessary for component substitution.
