Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV431AILP is determined by electrical parameter equivalence and regulatory compliance. The primary substitute, TLV431AIDBZR, maintains identical electrical specifications: shunt reference type, adjustable output topology, 1.24V minimum output, 6V maximum output, 15mA output current, ±1% tolerance, and 80µA cathode current. Both devices operate across the same temperature range (-40°C ~ 85°C) and maintain ROHS3 compliance.

The key differentiator between these parts is packaging and mounting technology. The TLV431AILP uses through-hole TO-92-3 packaging, while the TLV431AIDBZR uses surface-mount SOT-23-3 packaging. This distinction affects PCB layout, assembly process, and supply chain availability but does not alter electrical performance or functional compatibility in equivalent circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The TLV431AIDBZR is the direct electrical equivalent to the TLV431AILP and is recommended for new designs and production continuity. Both devices are manufactured by Texas Instruments and share identical electrical performance specifications. The TLV431AIDBZR maintains active product status, ensuring long-term availability and supply chain stability compared to the Last Time Buy status of the TLV431AILP.

Selection between these parts depends on PCB assembly requirements. The TLV431AILP is suitable for through-hole assembly processes, while the TLV431AIDBZR is designed for surface-mount assembly. Both devices maintain ROHS3 compliance and are suitable for applications requiring precision voltage reference functionality across industrial temperature ranges.

Frequently Asked Questions (FAQ)

Q: Can TLV431AIDBZR replace TLV431AILP in existing designs?

A: Yes, electrically. The TLV431AIDBZR provides identical voltage reference performance, output current capability, and tolerance specifications. PCB layout and assembly process modifications are required due to different package types (SOT-23-3 surface mount versus TO-92-3 through hole).

Q: What are the electrical differences between these parts?

A: There are no electrical differences. Both devices deliver 1.24V minimum adjustable output to 6V maximum, 15mA output current, ±1% tolerance, and 80µA cathode current across -40°C to 85°C operating temperature.

Q: Why is TLV431AILP marked as Last Time Buy?

A: Last Time Buy status indicates the manufacturer is discontinuing this product line. The TLV431AIDBZR represents the active alternative, offering the same electrical functionality in a modern surface-mount package format.

Q: Are there compliance or certification differences?

A: Both parts maintain ROHS3 compliance and REACH Unaffected status. Regulatory certifications are equivalent between the two devices.

Q: What inventory considerations apply?

A: TLV431AILP has 4,735 pieces available as Last Time Buy stock. TLV431AIDBZR has 68,400 pieces in active inventory, providing greater supply availability for ongoing production requirements.
