Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BZX584B16-TP are qualified based on strict electrical and mechanical parameter equivalence. The following criteria determine substitution eligibility:

Electrical Parameters (Must Match):

• Voltage - Zener (Nom): 16 V
• Tolerance: ±2%
• Power - Max: 150 mW
• Impedance (Max): 40 Ohms
• Current - Reverse Leakage @ Vr: 100 nA @ 11.2 V
• Voltage - Forward (Vf) (Max) @ If: 900 mV @ 10 mA
• Operating Temperature Range: -55°C to 150°C (TJ)

Mechanical Parameters (Must Match):

• Mounting Type: Surface Mount
• Package / Case: SC-79, SOD-523
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts maintain identical electrical specifications and package compatibility with the main part number BZX584B16-TP. Variations in manufacturer, packaging format (Tape & Reel vs. Cut Tape), and optional automotive qualification do not affect functional equivalence for standard applications.

Parameter Comparison

Engineering Selection Recommendations

BZX584B16HE3-TP (Micro Commercial Co): This substitute maintains complete electrical and mechanical equivalence to the BZX584B16-TP. The primary distinction is AEC-Q101 automotive qualification, which indicates compliance with automotive reliability standards. This part is suitable for applications requiring automotive-grade components or where enhanced qualification documentation is required. Inventory availability is significantly higher at 15,212 pieces.

BZX584B16 RSG (Taiwan Semiconductor Corporation): This substitute provides full electrical equivalence with identical Zener voltage, power rating, impedance, and operating temperature range. The manufacturer is Taiwan Semiconductor Corporation with Cut Tape and Digi-Reel packaging options. Inventory availability is substantially higher at 105,093 pieces. The supplier device package designation SOD-523F indicates a variant of the SOD-523 package. All regulatory compliance parameters (RoHS3, REACH Unaffected, EAR99) are maintained.

Selection between substitute parts depends on procurement requirements, packaging format preference, and inventory availability. All three parts are Active in product status and maintain identical functional performance for standard voltage regulation and protection applications.

Frequently Asked Questions (FAQ)

Q: Can BZX584B16HE3-TP be used as a direct replacement for BZX584B16-TP?

A: Yes. The BZX584B16HE3-TP maintains identical electrical specifications including 16 V Zener voltage, ±2% tolerance, 150 mW power rating, 40 Ohms maximum impedance, and -55°C to 150°C operating temperature range. Both parts use the same SOD-523 package and are ROHS3 compliant with MSL 1 rating. The primary difference is AEC-Q101 automotive qualification on the HE3-TP variant.

Q: Can BZX584B16 RSG from Taiwan Semiconductor be used as a direct replacement for BZX584B16-TP?

A: Yes. The BZX584B16 RSG provides complete electrical equivalence with matching Zener voltage, tolerance, power dissipation, impedance, reverse leakage current, and operating temperature specifications. The SOD-523 package is mechanically compatible. Packaging format differs (Cut Tape & Digi-Reel versus Tape & Reel), but this does not affect functional performance.

Q: What are the key parameters that determine if a Zener diode can substitute for BZX584B16-TP?

A: Substitution requires matching of the following parameters: Voltage - Zener (Nom) at 16 V, Tolerance at ±2%, Power - Max at 150 mW, Impedance (Max) at 40 Ohms, Current - Reverse Leakage @ Vr at 100 nA @ 11.2 V, Operating Temperature Range from -55°C to 150°C, Surface Mount mounting type, and SOD-523 package configuration. RoHS3 compliance and MSL 1 rating must also be maintained.

Q: Does the SOD-523F package designation on BZX584B16 RSG affect compatibility?

A: No. The SOD-523F is a variant designation of the SOD-523 package family. Both the standard SOD-523 and SOD-523F maintain the same mechanical footprint and electrical interface required for the SC-79 package specification. This does not impact PCB assembly or functional performance.

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

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, suitable for high-volume automated assembly. Cut Tape (CT) supplies components on tape segments cut to specific lengths, suitable for lower-volume or mixed-component orders. Digi-Reel is a proprietary reel format. These packaging differences do not affect component electrical performance or mechanical compatibility.

Q: Are all three parts suitable for automotive applications?

A: The BZX584B16HE3-TP carries explicit AEC-Q101 automotive qualification. The BZX584B16-TP and BZX584B16 RSG do not specify automotive qualification in their data. For applications requiring documented automotive-grade components, the BZX584B16HE3-TP is the appropriate selection.

Q: What is the significance of the higher inventory levels for substitute parts?

A: BZX584B16HE3-TP has 15,212 pieces in stock and BZX584B16 RSG has 105,093 pieces in stock, compared to 936 pieces for the main part BZX584B16-TP. Higher inventory availability may reduce lead times and support continuous production requirements. Inventory levels do not affect electrical performance or substitution eligibility.
