TLV431CLP Equivalent & Substitute Parts

Part Overview

The TLV431CLP is a shunt voltage reference IC with adjustable output, manufactured by Texas Instruments. It provides a fixed minimum output of 1.24V with a maximum adjustable output up to 6V, delivering 15mA output current with ±1.5% tolerance. The device is packaged in TO-92-3 (through-hole) configuration and operates across 0°C to 70°C.

The TLV431CLP is designated as Last Time Buy, indicating end-of-life status. Identifying equivalent substitute parts is necessary for design continuity, long-term availability, and production planning. The primary substitute maintains identical electrical specifications while offering improved availability and extended operating temperature range.

Substitute Part Grouping Explanation

Substitution of the TLV431CLP is determined by strict equivalence across the following electrical and mechanical parameters:

• Reference Type: Shunt (identical function)
• Output Type: Adjustable (identical configuration)
• Voltage - Output (Min/Fixed): 1.24V (identical)
• Voltage - Output (Max): 6V (identical)
• Current - Output: 15mA (identical)
• Tolerance: ±1.5% (identical)
• Current - Cathode: 80µA (identical)
• Base Product Number: TLV431 (same device family)

The TLV431IDBZR qualifies as a direct electrical equivalent. The primary difference is packaging format: TLV431IDBZR uses surface-mount SOT-23-3 instead of through-hole TO-92-3. This substitution is valid only when PCB layout and assembly process accommodate surface-mount technology.

Parameter Comparison

Engineering Selection Recommendations

The TLV431IDBZR is the active product replacement for the TLV431CLP. Both devices maintain identical electrical specifications and share ROHS3 compliance. Selection between these parts depends on assembly methodology:

For through-hole assembly processes, the TLV431CLP remains functional until inventory depletion. However, given Last Time Buy status, new designs should transition to TLV431IDBZR to ensure long-term supply continuity.

For surface-mount assembly processes, TLV431IDBZR is the direct equivalent with superior availability (21,400 units in stock versus 1,115 units for TLV431CLP) and extended operating temperature range (-40°C to 85°C versus 0°C to 70°C).

Both parts carry identical regulatory compliance (ROHS3, REACH Unaffected, EAR99 classification).

Frequently Asked Questions (FAQ)

Q: Can TLV431IDBZR replace TLV431CLP in existing designs?

A: Electrical substitution is valid. The TLV431IDBZR provides identical voltage reference performance, output current, and tolerance specifications. Substitution requires PCB redesign to accommodate SOT-23-3 surface-mount package instead of TO-92-3 through-hole package. Pin configuration differs between packages.

Q: What is the difference in operating temperature range?

A: TLV431CLP operates 0°C to 70°C. TLV431IDBZR operates -40°C to 85°C. The extended range of TLV431IDBZR provides broader environmental coverage. For applications within 0°C to 70°C, both devices are equivalent.

Q: Why is TLV431CLP designated Last Time Buy?

A: Last Time Buy status indicates Texas Instruments has discontinued this product line in favor of surface-mount alternatives. This designation signals end-of-life and recommends migration to active products such as TLV431IDBZR.

Q: Are there other TLV431 variants available?

A: The TLV431 family includes multiple package options. Substitution is valid only within the TLV431 base product number when electrical parameters remain identical. Verify package compatibility with your assembly process before selection.

Q: What certifications apply to both parts?

A: Both TLV431CLP and TLV431IDBZR are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.
