Substitute Part Grouping Explanation

Substitution of the TLV431CDBZRG4 is determined by strict equivalence across the following critical parameters:

• Reference Type: Shunt
• Output Type: Adjustable
• Voltage - Output (Min/Fixed): 1.24V
• Voltage - Output (Max): 6V
• Current - Output: 15 mA
• Tolerance: ±1.5%
• Current - Cathode: 80 µA
• Operating Temperature: 0°C ~ 70°C (TA)
• Package / Case: TO-236-3, SC-59, SOT-23-3
• Mounting Type: Surface Mount

The TLV431CDBZR qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is packaging format: the main part is supplied in standard packaging, while the substitute is available in Tape & Reel (TR) format. Both parts share the same base product number (TLV431) and maintain full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The TLV431CDBZR is the recommended substitute for the obsolete TLV431CDBZRG4. Both parts are manufactured by Texas Instruments and maintain identical electrical performance specifications. The substitute part carries Active product status, ensuring continued availability and manufacturing support. Both components satisfy ROHS3 compliance and REACH requirements, making them suitable for applications with regulatory compliance mandates. The transition from the obsolete part to the active equivalent involves no electrical redesign or circuit modification, as all functional parameters remain unchanged. Packaging format differences (standard versus Tape & Reel) affect procurement and assembly processes but do not impact electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can TLV431CDBZR be used as a direct replacement for TLV431CDBZRG4?

A: Yes. Both parts are electrically and mechanically identical. The TLV431CDBZR is the active equivalent with the same voltage reference specifications, output current rating, tolerance, and SOT-23-3 package configuration.

Q: What is the difference between TLV431CDBZRG4 and TLV431CDBZR?

A: The primary difference is product status and packaging format. TLV431CDBZRG4 is obsolete with standard packaging, while TLV431CDBZR is active and supplied in Tape & Reel (TR) format. Electrical specifications are identical.

Q: Are there any circuit modifications required when switching from TLV431CDBZRG4 to TLV431CDBZR?

A: No circuit modifications are required. The substitute part maintains all electrical parameters including output voltage range (1.24V to 6V), output current (15 mA), tolerance (±1.5%), and operating temperature range (0°C to 70°C).

Q: Does the Tape & Reel packaging of TLV431CDBZR affect circuit performance?

A: No. Tape & Reel packaging is a procurement and assembly format only. It does not affect the electrical characteristics or performance of the component when soldered onto the PCB.

Q: Are both parts RoHS compliant?

A: Yes. Both TLV431CDBZRG4 and TLV431CDBZR are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life without moisture control requirements.
