UDZS13B RRG Equivalent & Substitute Parts

Part Overview

The UDZS13B RRG is a Zener diode manufactured by Taiwan Semiconductor Corporation, rated at 13 V nominal voltage with 200 mW power dissipation capability. This surface mount component operates across the temperature range of -55°C to 150°C and is packaged in the SOD-323F form factor. The device maintains Active product status and carries full RoHS3 compliance certification.

Equivalent and substitute parts are identified to address supply chain requirements, inventory availability, and packaging format preferences while maintaining electrical and mechanical compatibility within the specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the UDZS13B RRG are classified based on strict electrical and mechanical parameter alignment. The substitution logic is determined by the following critical parameters:

Primary Substitution Criteria:

• Voltage - Zener (Nom): 13 V
• Power - Max: 200 mW
• Tolerance: ±2%
• Package / Case: SOD-323F
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant

Parametric Equivalent Classification: The UDZS13B R9G is classified as a parametric equivalent. This part shares identical electrical specifications (13 V, 200 mW, ±2% tolerance) and mechanical packaging (SOD-323F) with the main part. The difference lies in packaging format: UDZS13B R9G is supplied in Cut Tape (CT) & Digi-Reel® format, whereas UDZS13B RRG uses standard reel packaging.

Similar Manufacturer Classification: The MM3Z13VB (onsemi) is classified as a similar manufacturer part. While it maintains the same nominal voltage (13 V), power rating (200 mW), tolerance (±2%), and SOD-323F package, it exhibits variations in secondary parameters: impedance (28 Ohms versus 40 Ohms maximum) and reverse leakage current (900 nA @ 8 V versus 45 nA @ 10 V). The operating temperature range extends to -65°C minimum, providing broader low-temperature performance.

Parameter Comparison

Engineering Selection Recommendations

UDZS13B R9G Selection: The UDZS13B R9G is the direct parametric equivalent for applications requiring identical electrical performance to the UDZS13B RRG. Both parts are manufactured by Taiwan Semiconductor Corporation and maintain identical specifications across all critical parameters. Selection of UDZS13B R9G is appropriate when Cut Tape & Digi-Reel® packaging format is compatible with assembly processes. Both parts carry Active product status and full RoHS3 compliance.

MM3Z13VB Selection: The MM3Z13VB (onsemi) is suitable for applications where the following conditions are met: (1) extended low-temperature operation to -65°C is required, (2) lower impedance characteristics (28 Ohms) are beneficial to circuit performance, or (3) supply chain availability of onsemi components is preferred. The MM3Z13VB maintains identical nominal voltage, power rating, tolerance, and package format. The higher reverse leakage current specification (900 nA @ 8 V) must be evaluated against circuit requirements. All compliance certifications (RoHS3, REACH Unaffected) are maintained.

Compliance and Regulatory Considerations: All listed parts maintain ROHS3 compliance, Moisture Sensitivity Level 1 (Unlimited), and REACH Unaffected status. ECCN classification (EAR99) and HTSUS code (8541.10.0050) are consistent across all parts, ensuring regulatory equivalence for export and procurement purposes.

Frequently Asked Questions (FAQ)

Q: Can UDZS13B R9G be used as a direct replacement for UDZS13B RRG?

A: Yes. The UDZS13B R9G is a parametric equivalent with identical electrical specifications (13 V, 200 mW, ±2% tolerance, 40 Ohms impedance) and mechanical packaging (SOD-323F). The only difference is the packaging format (Cut Tape & Digi-Reel® versus standard reel). Compatibility depends on assembly equipment compatibility with the packaging format.

Q: What are the key differences between MM3Z13VB and UDZS13B RRG?

A: The MM3Z13VB differs in three parameters: (1) impedance is 28 Ohms maximum versus 40 Ohms, (2) reverse leakage current is 900 nA @ 8 V versus 45 nA @ 10 V, and (3) minimum operating temperature extends to -65°C versus -55°C. Nominal voltage, power rating, tolerance, and package format remain identical.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. UDZS13B RRG, UDZS13B R9G, and MM3Z13VB all carry ROHS3 Compliant certification. All parts also maintain REACH Unaffected status and Moisture Sensitivity Level 1 (Unlimited).

Q: Which part should be selected for applications requiring the lowest reverse leakage current?

A: UDZS13B RRG and UDZS13B R9G both specify 45 nA @ 10 V reverse leakage current. The MM3Z13VB specifies 900 nA @ 8 V, which is higher. Selection of UDZS13B RRG or UDZS13B R9G is appropriate for applications with strict reverse leakage requirements.

Q: Is the MM3Z13VB suitable for low-temperature applications?

A: The MM3Z13VB operates to -65°C minimum, compared to -55°C for UDZS13B RRG and UDZS13B R9G. Applications requiring operation below -55°C should specify MM3Z13VB.

Q: What is the difference between UDZS13B RRG and UDZS13B R9G packaging?

A: UDZS13B RRG uses standard reel packaging, while UDZS13B R9G is supplied in Cut Tape (CT) & Digi-Reel® format. Both use the SOD-323F package case. Selection depends on assembly line equipment and tape format compatibility.

Q: Can these parts be used interchangeably in all circuit applications?

A: UDZS13B RRG and UDZS13B R9G are fully interchangeable. MM3Z13VB is interchangeable for most applications; however, circuits sensitive to impedance or reverse leakage current specifications should be evaluated for the parameter differences noted in the comparison table.
