UDZS7V5B Equivalent & Substitute Parts

Part Overview

The UDZS7V5B is an active-status Zener diode manufactured by Taiwan Semiconductor Corporation, designed for surface mount applications in the SOD-323F package. This component provides voltage regulation and transient protection in electronic circuits. The 7.5 V nominal Zener voltage with ±2% tolerance and 200 mW power rating establishes the functional baseline for identifying equivalent and substitute components. Substitute parts are identified when identical electrical specifications and mechanical compatibility are maintained across alternative packaging configurations or supplier distribution channels.

Substitute Part Grouping Explanation

Substitution of the UDZS7V5B is determined by strict equivalence across the following critical parameters:

• Voltage - Zener (Nom): 7.5 V
• Tolerance: ±2%
• Power - Max: 200 mW
• Impedance (Max): 30 Ohms
• Current - Reverse Leakage @ Vr: 900 nA @ 4 V
• Operating Temperature Range: -55°C to 150°C (TJ)
• Package / Case: SC-90, SOD-323F
• Mounting Type: Surface Mount

The substitute part UDZS7V5B R9G maintains identical electrical characteristics and mechanical compatibility. The distinction between the main part and substitute lies exclusively in packaging configuration (Tape & Reel versus Cut Tape & Digi-Reel®) and inventory availability, with no impact on functional performance or circuit integration.

Parameter Comparison

Engineering Selection Recommendations

Both UDZS7V5B and UDZS7V5B R9G are active-status components manufactured by Taiwan Semiconductor Corporation with full ROHS3 compliance and REACH unaffected status. Selection between these parts is determined by procurement and assembly requirements rather than electrical or thermal performance.

UDZS7V5B (Tape & Reel packaging) is suitable for high-volume automated assembly operations requiring continuous reel-fed component delivery.

UDZS7V5B R9G (Cut Tape & Digi-Reel® packaging) accommodates both manual assembly workflows and automated pick-and-place systems with flexible reel configurations. This variant maintains higher current inventory levels (10,683 Pcs versus 913 Pcs), supporting shorter lead times and reduced procurement delays.

Both parts satisfy identical electrical specifications, thermal operating ranges, and regulatory requirements. Component selection should be based on assembly methodology, inventory availability, and supply chain logistics.

Frequently Asked Questions (FAQ)

Q: Are UDZS7V5B and UDZS7V5B R9G electrically identical?

A: Yes. Both components share identical Zener voltage (7.5 V), tolerance (±2%), power rating (200 mW), impedance (30 Ohms maximum), reverse leakage current (900 nA @ 4 V), and operating temperature range (-55°C to 150°C). Electrical performance and circuit behavior are equivalent.

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

A: Tape & Reel (TR) delivers components on continuous reels optimized for automated high-speed assembly lines. Cut Tape (CT) & Digi-Reel® provides components in tape segments compatible with both manual assembly and flexible automated systems. Both packaging formats contain identical components in the SOD-323F package.

Q: Can UDZS7V5B R9G be used as a direct replacement for UDZS7V5B?

A: Yes. The UDZS7V5B R9G is a direct parametric equivalent with identical electrical specifications, mechanical dimensions, and regulatory compliance. Substitution is valid for all circuit applications requiring a 7.5 V Zener diode with 200 mW power rating and ±2% tolerance.

Q: Are there any compliance or certification differences between these parts?

A: No. Both components maintain identical RoHS3 compliance, REACH unaffected status, EAR99 export classification, and HTSUS tariff code (8541.10.0050). Regulatory and environmental requirements are equivalent.

Q: Which part should be selected for new designs?

A: Selection depends on manufacturing infrastructure. For high-volume automated assembly, UDZS7V5B (Tape & Reel) is standard. For flexible manufacturing or lower-volume production, UDZS7V5B R9G (Cut Tape & Digi-Reel®) provides operational flexibility. Both are equally suitable for new circuit designs.

Q: Is the SOD-323F package compatible with standard PCB assembly equipment?

A: Yes. The SOD-323F package (SC-90 case) is a standard surface mount package compatible with conventional pick-and-place equipment and reflow soldering processes. Both UDZS7V5B variants use this industry-standard package.
