TPS2022P Equivalent & Substitute Parts

Part Overview

The TPS2022P is a power management integrated circuit (PMIC) functioning as a general-purpose N-channel power switch with 1:1 input-to-output ratio and high-side output configuration. Designed for load switching applications, it delivers a maximum output current of 1A with integrated fault protection including current limiting, over-temperature shutdown, and under-voltage lockout (UVLO). The device operates across a load voltage range of 2.7V to 5.5V and a junction temperature range of -40°C to 125°C.

The TPS2022P is classified as obsolete. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term product availability for applications currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPS2022P is determined by strict equivalence across the following critical parameters:

• Functional Architecture: 1:1 input-to-output ratio, high-side N-channel output configuration, general-purpose switch topology
• Electrical Performance: Maximum output current of 1A, typical on-resistance of 33mOhm, load voltage range of 2.7V to 5.5V
• Control Interface: Inverting on/off logic with status flag output
• Protection Features: Current limiting (fixed), over-temperature shutdown, and UVLO
• Operating Conditions: Junction temperature range of -40°C to 125°C
• Regulatory Compliance: ROHS3 compliance, REACH unaffected status, EAR99 classification

The TPS2022D is identified as a manufacturer-recommended substitute. It maintains identical electrical specifications and functional characteristics as the TPS2022P while differing only in packaging format (surface-mount 8-SOIC versus through-hole 8-DIP) and product status (active versus obsolete).

Parameter Comparison

Engineering Selection Recommendations

The TPS2022D is the manufacturer-recommended substitute for the obsolete TPS2022P. Both devices share identical electrical specifications, functional architecture, and regulatory compliance status (ROHS3 compliant, REACH unaffected, EAR99 classification).

The primary distinction between these parts is packaging format and product lifecycle status. The TPS2022P uses through-hole 8-DIP packaging suitable for breadboard and conventional PCB assembly, while the TPS2022D employs surface-mount 8-SOIC packaging optimized for automated assembly and compact board layouts. The TPS2022D maintains active product status with established supply chain availability, whereas the TPS2022P is classified as obsolete.

Selection of the TPS2022D requires PCB redesign to accommodate surface-mount assembly and 8-SOIC footprint geometry. Applications constrained to through-hole assembly or existing PCB layouts designed for 8-DIP packaging must evaluate alternative suppliers or consider board-level redesign to transition to surface-mount technology.

Frequently Asked Questions (FAQ)

Q: Are the TPS2022P and TPS2022D electrically interchangeable?

A: Yes. Both devices maintain identical electrical specifications including maximum output current (1A), on-resistance (33mOhm typical), load voltage range (2.7V to 5.5V), operating temperature range (-40°C to 125°C), and fault protection features (current limiting, over-temperature, UVLO). Functional compatibility is complete.

Q: What is the primary difference between these parts?

A: The TPS2022P uses through-hole 8-DIP packaging (0.300", 7.62mm), while the TPS2022D uses surface-mount 8-SOIC packaging (0.154", 3.90mm width). Additionally, the TPS2022P is obsolete, whereas the TPS2022D maintains active product status.

Q: Can I use the TPS2022D as a direct replacement without PCB modification?

A: No. The different package formats (8-DIP versus 8-SOIC) require different PCB footprints and assembly processes. Through-hole and surface-mount technologies are not mechanically compatible on the same board layout. PCB redesign is necessary.

Q: Why is the TPS2022P obsolete?

A: Product obsolescence is determined by the manufacturer. The TPS2022D represents the active continuation of this product line with identical electrical performance and enhanced supply chain availability.

Q: Are both parts RoHS compliant?

A: Yes. Both the TPS2022P and TPS2022D are ROHS3 compliant with MSL rating of 1 (unlimited moisture sensitivity level).
