TL430CLPE3 Equivalent & Substitute Parts

Part Overview

The TL430CLPE3 is a shunt voltage reference IC with adjustable output, classified as a Power Management (PMIC) component. This through-hole mounted device operates in the 2.75V to 30V output range with ±9.09% tolerance and 100 mA output current capability. The product status is listed as Obsolete, necessitating identification of equivalent and substitute parts for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TL430CLPE3 is determined by the following critical parameters: reference type (shunt), output type (adjustable), output voltage range compatibility, output current capability, tolerance specification, and package/mounting type compatibility.

The substitute parts are grouped into two categories:

Manufacturer Recommended Substitute: TL431AIDBZR represents an upgraded alternative from Texas Instruments with improved tolerance (±1% vs ±9.09%), extended voltage range (36V vs 30V maximum), and surface-mount packaging. This part maintains the same 100 mA output current and adjustable output type.

Parametric Equivalent: TL430CLP provides direct parametric equivalence to the TL430CLPE3, maintaining identical electrical specifications (2.75V to 30V output, ±9.09% tolerance, 120ppm/°C temperature coefficient, 650µVp-p noise) and through-hole TO-92-3 packaging. The primary difference is product status (Last Time Buy vs Obsolete) and packaging format (Bulk vs standard).

Engineering Selection Recommendations

For Direct Replacement (Through-Hole PCB): TL430CLP is the appropriate selection when board layout and mounting infrastructure require through-hole components. This part maintains identical electrical performance and thermal characteristics as the TL430CLPE3 while offering improved product status (Last Time Buy provides extended availability compared to Obsolete status).

For Design Upgrade or New Designs: TL431AIDBZR is the manufacturer-recommended substitute, particularly when design constraints permit surface-mount implementation. This part offers superior tolerance specification (±1%), extended operating temperature range (-40°C to 85°C), and higher maximum voltage rating (36V). The transition from through-hole to surface-mount packaging requires PCB redesign but provides enhanced performance margins and active product status with long-term availability.

Compliance Considerations: All three parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment across substitution options.

Frequently Asked Questions (FAQ)

Q: Can TL431AIDBZR directly replace TL430CLPE3 on existing PCBs?

A: No. TL431AIDBZR uses SOT-23-3 surface-mount packaging while TL430CLPE3 uses TO-92-3 through-hole packaging. PCB redesign is required. However, the electrical functionality is compatible for applications within the specified voltage and current ranges.

Q: What are the key electrical differences between TL430CLPE3 and TL431AIDBZR?

A: TL431AIDBZR provides ±1% tolerance compared to ±9.09% for TL430CLPE3, a 36V maximum output versus 30V, and operates across -40°C to 85°C versus 0°C to 70°C. The minimum output voltage is slightly lower (2.495V vs 2.75V). Cathode current is reduced to 700 µA from 2 mA.

Q: Is TL430CLP electrically identical to TL430CLPE3?

A: Yes. TL430CLP maintains identical electrical specifications, temperature coefficient, noise characteristics, and TO-92-3 packaging. The primary distinction is product status and packaging format (Bulk vs standard).

Q: Which substitute should be selected for new designs?

A: TL431AIDBZR is the manufacturer-recommended choice for new designs, offering superior tolerance, extended temperature range, and active product status. Surface-mount implementation is standard in modern PCB design practices.

Q: Are there any thermal or noise performance differences?

A: TL430CLP matches the TL430CLPE3 thermal coefficient (120ppm/°C) and noise specification (650µVp-p, 0.1Hz to 10Hz). TL431AIDBZR does not specify these parameters in the provided data.
