Substitute Part Grouping Explanation

Substitution of the BZX584B3V0-TP is determined by strict equivalence across the following critical parameters:

• Zener Voltage (Vz): 3 V nominal
• Tolerance: ±2%
• Maximum Power Dissipation: 150 mW
• Impedance (Zzt): 95 Ohms maximum
• Reverse Leakage Current: 10 µA @ 1 V
• Forward Voltage: 900 mV maximum @ 10 mA
• Operating Temperature Range: -55°C to 150°C (TJ)
• Package Type: SOD-523 surface mount
• Compliance: RoHS3 compliant, REACH unaffected

The substitute part BZX584B3V0 RSG, manufactured by Taiwan Semiconductor Corporation, meets all electrical and mechanical specifications. Packaging format differs (Cut Tape & Digi-Reel® versus Tape & Reel), but the component package remains SOD-523 compatible.

Parameter Comparison

Engineering Selection Recommendations

Both the BZX584B3V0-TP and BZX584B3V0 RSG are Active status components with identical electrical specifications and full regulatory compliance. Selection between these parts is based on:

Supply Chain Availability: The BZX584B3V0 RSG (Taiwan Semiconductor Corporation) maintains higher inventory levels (8971 Pcs) compared to the BZX584B3V0-TP (680 Pcs), providing improved procurement lead times and stock continuity.

Packaging Format: The BZX584B3V0-TP is supplied in Tape & Reel (TR) format, while the BZX584B3V0 RSG is supplied in Cut Tape (CT) & Digi-Reel® format. Both formats are compatible with standard surface mount assembly equipment; selection depends on production volume and handling requirements.

Regulatory Compliance: Both parts maintain ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity levels, ensuring equivalent performance in regulated applications.

Electrical Equivalence: All critical parameters—zener voltage, tolerance, power rating, impedance, leakage current, forward voltage, and operating temperature range—are identical, confirming direct functional substitution.

Frequently Asked Questions (FAQ)

Q: Can BZX584B3V0 RSG replace BZX584B3V0-TP in existing designs?

A: Yes. Both components are parametrically equivalent across all electrical specifications, operating temperature range, and package type (SOD-523). Direct substitution is supported without circuit modification.

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

A: Tape & Reel (TR) supplies components on continuous carrier tape in reel format for high-volume automated assembly. Cut Tape (CT) & Digi-Reel® supplies components on cut tape segments or alternative reel formats. Both are compatible with standard pick-and-place equipment; selection depends on production volume and assembly line configuration.

Q: Are there any compliance differences between these parts?

A: No. Both BZX584B3V0-TP and BZX584B3V0 RSG maintain identical RoHS3 compliance, REACH unaffected status, and Moisture Sensitivity Level 1 (Unlimited). They are equivalent for regulated applications.

Q: What parameters determine substitution eligibility for Zener diodes?

A: Zener voltage (Vz), tolerance, maximum power dissipation, impedance, reverse leakage current, forward voltage, operating temperature range, and package type must all match. The BZX584B3V0 RSG meets all these criteria for the BZX584B3V0-TP.

Q: Can these parts be used interchangeably in voltage regulation circuits?

A: Yes. Identical zener voltage (3 V), tolerance (±2%), impedance (95 Ohms max), and reverse leakage characteristics (10 µA @ 1 V) ensure equivalent performance in voltage regulation, overvoltage protection, and reference voltage applications.

Q: What is the significance of the ±2% tolerance specification?

A: The ±2% tolerance indicates the maximum deviation of the actual zener voltage from the nominal 3 V specification. Both parts maintain this tolerance, ensuring predictable voltage regulation performance across production batches.
