TPS2033P Equivalent & Substitute Parts

Part Overview

The TPS2033P is a Power Management Integrated Circuit (PMIC) functioning as a power switch/driver with 1:1 configuration and N-Channel output topology. This component operates as a high-side switch rated for 1.5A maximum output current with integrated fault protection including current limiting, over-temperature monitoring, and under-voltage lockout (UVLO). The TPS2033P is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPS2033P is determined by the following critical parameters:

• Electrical Compatibility: Voltage range (2.7V ~ 5.5V), maximum output current (1.5A), and on-resistance (33mOhm typical)
• Functional Topology: High-side N-Channel output configuration with 1:1 ratio and On/Off interface
• Protection Features: Current limiting (fixed), over-temperature protection, and UVLO
• Thermal Range: Operating temperature -40°C ~ 125°C (TJ)
• Compliance: RoHS3 compliance and REACH unaffected status

Two substitute parts meet these criteria with variations in packaging and product status:

MFR Recommended Substitute (TPS2033D): Identical electrical and functional specifications with surface-mount packaging (8-SOIC) and active product status.

Parametric Equivalent (TPS2023P): Matches all electrical specifications and through-hole packaging with one functional difference in input type (inverting vs. non-inverting).

Parameter Comparison

Engineering Selection Recommendations

TPS2033D (MFR Recommended Substitute): This is the primary substitute for the obsolete TPS2033P. It provides identical electrical specifications and functional characteristics with the advantage of active product status and established supply chain availability (2800 pcs in stock). The only design consideration is the transition from through-hole (8-DIP) to surface-mount (8-SOIC) packaging, which requires PCB layout modification. Both parts maintain ROHS3 compliance and REACH unaffected status.

TPS2023P (Parametric Equivalent): This part matches all electrical parameters and maintains through-hole packaging compatibility with the original TPS2033P, eliminating PCB redesign requirements. However, the input type differs (inverting vs. non-inverting), which affects signal logic and control circuit design. This part is suitable only when the inverting input characteristic aligns with system requirements. Product status is active with adequate inventory (1229 pcs in stock).

Frequently Asked Questions (FAQ)

Q: Can TPS2033D directly replace TPS2033P without PCB modification?

A: TPS2033D provides complete electrical and functional equivalence but requires PCB layout changes due to package transition from 8-DIP (through-hole) to 8-SOIC (surface-mount). Footprint, trace routing, and assembly process differ between these mounting types.

Q: What is the key difference between TPS2033D and TPS2023P?

A: Both parts share identical electrical specifications (1.5A output, 33mOhm Rds On, 2.7V-5.5V load voltage). The primary difference is input type: TPS2033D maintains non-inverting input logic matching the original TPS2033P, while TPS2023P uses inverting input logic. Additionally, TPS2033D uses surface-mount packaging (8-SOIC) while TPS2023P retains through-hole packaging (8-DIP).

Q: Is TPS2023P suitable as a direct replacement if I need to avoid PCB redesign?

A: TPS2023P maintains the same through-hole 8-DIP package as TPS2033P, allowing direct PCB compatibility. However, the inverting input requires control circuit modification. This substitution is valid only when the inverting input characteristic is compatible with your system design.

Q: Are all three parts RoHS and REACH compliant?

A: Yes. TPS2033P, TPS2033D, and TPS2023P are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the inventory status for each part?

A: TPS2033P (obsolete) has 715 pcs in stock. TPS2033D (active) has 2800 pcs in stock. TPS2023P (active) has 1229 pcs in stock. For long-term production, active-status parts (TPS2033D or TPS2023P) are recommended.
