TPS2055P Equivalent & Substitute Parts

Part Overview

The TPS2055P is a Power Management Integrated Circuit (PMIC) functioning as a power switch/driver with 1:1 N-Channel configuration and 250mA output capability. Manufactured by Texas Instruments, this component operates across a 2.7V to 5.5V load voltage range with integrated fault protection including current limiting, over-temperature monitoring, and under-voltage lockout (UVLO). The TPS2055P is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitution eligibility for the TPS2055P is determined by strict equivalence across the following critical parameters:

  • Functional Architecture: 1:1 N-Channel high-side power switch configuration
  • Electrical Performance: 250mA maximum output current, 80mOhm typical on-resistance, 2.7V to 5.5V load voltage range
  • Protection Features: Current limiting, over-temperature protection, and UVLO functionality
  • Thermal Range: -40°C to 85°C operating temperature
  • Compliance: ROHS3 compliance and REACH unaffected status

The TPS2055D qualifies as a direct functional substitute, maintaining identical electrical specifications and protection characteristics while differing only in packaging format and mounting technology.

Engineering Selection Recommendations

The TPS2055D is the manufacturer-recommended substitute for the obsolete TPS2055P. Both components maintain identical electrical specifications, protection mechanisms, and compliance certifications. Selection between these parts depends on design requirements:

TPS2055P (Through-Hole DIP): Suitable for legacy systems, breadboard prototyping, and applications requiring through-hole mounting technology.

TPS2055D (Surface-Mount SOIC): Recommended for new designs, high-density PCB layouts, and modern manufacturing processes. Active product status ensures long-term availability and supply chain continuity.

Both variants satisfy ROHS3 compliance and REACH requirements, with unlimited moisture sensitivity classification appropriate for standard industrial environments.

Frequently Asked Questions (FAQ)

Q: Can TPS2055D directly replace TPS2055P in existing designs?

A: Electrical and functional compatibility is complete. PCB layout modification is required due to package format differences (8-DIP through-hole versus 8-SOIC surface-mount). Pin-to-pin functionality remains identical.

Q: Why is TPS2055P classified as obsolete?

A: The TPS2055P through-hole DIP package represents legacy technology. Texas Instruments transitioned the TPS2055 product line to surface-mount SOIC packaging (TPS2055D) to align with modern manufacturing standards and reduce production costs.

Q: Are there electrical performance differences between TPS2055P and TPS2055D?

A: No. Both variants deliver 250mA maximum output current, 80mOhm on-resistance, and identical fault protection features across the 2.7V to 5.5V load voltage range.

Q: What compliance certifications apply to both parts?

A: Both TPS2055P and TPS2055D are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (unlimited moisture sensitivity).

Q: Which part should be selected for new product development?

A: TPS2055D is the appropriate choice for new designs. Active product status guarantees manufacturer support, ongoing availability, and compatibility with current supply chain infrastructure.
