TPS2058D Equivalent & Substitute Parts

Part Overview

The TPS2058D is a Power Management Integrated Circuit (PMIC) functioning as a power switch/driver with 2 x 1:2 configuration and N-Channel output topology. Manufactured by Texas Instruments, this component is designed for general-purpose switching applications requiring high-side output control with integrated fault protection. The TPS2058D is currently classified as obsolete, making identification of functionally equivalent active alternatives essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPS2058D is determined by strict equivalence across the following critical parameters:

• Electrical Configuration: 2 x 1:2 input-to-output ratio with 4 total outputs
• Output Topology: High-side N-Channel switching architecture
• Control Interface: On/Off logic control with non-inverting input
• Load Voltage Range: 2.7V ~ 5.5V operational window
• Current Capacity: 250mA maximum output current
• On-State Resistance: 80mOhm typical Rds(on)
• Fault Protection: Current limiting, over-temperature, and UVLO protection
• Thermal Range: 0°C ~ 85°C operating temperature
• Physical Form Factor: 16-SOIC surface-mount package

The TPS2058AD meets all specified parameters identically to the TPS2058D, establishing direct functional equivalence. The primary distinction is product lifecycle status: TPS2058D is obsolete while TPS2058AD maintains active production status.

Parameter Comparison

Engineering Selection Recommendations

The TPS2058AD is the direct functional equivalent for TPS2058D replacement. All electrical, mechanical, and thermal specifications are identical. The TPS2058AD carries active product status from Texas Instruments, ensuring continued availability, manufacturing support, and compliance with current regulatory standards including ROHS3 and REACH requirements.

For new designs or production continuity, the TPS2058AD is the appropriate selection. Both components share identical pinout, package footprint, and electrical performance characteristics, enabling direct substitution without circuit redesign or PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can TPS2058AD directly replace TPS2058D in existing designs?

A: Yes. The TPS2058AD is electrically and mechanically identical to the TPS2058D. Pinout, package dimensions, and all functional parameters match exactly, permitting direct substitution without design changes.

Q: Why is the TPS2058D classified as obsolete?

A: Product lifecycle management by Texas Instruments has transitioned the TPS2058D to obsolete status. The TPS2058AD maintains the same functionality and serves as the active production equivalent.

Q: Are there any compliance differences between TPS2058D and TPS2058AD?

A: No. Both components are ROHS3 compliant, REACH unaffected, and carry identical MSL ratings. Regulatory and environmental compliance is equivalent.

Q: What is the inventory status difference?

A: TPS2058D inventory is limited (786 units), reflecting its obsolete status. TPS2058AD maintains active inventory (3200 units), supporting ongoing procurement requirements.

Q: Is the 16-SOIC package identical for both parts?

A: Yes. Both components use the 16-SOIC package with 0.154" width and 3.90mm dimensions. PCB footprints are identical.

Q: What are the critical parameters for substitution verification?

A: Verify matching on: 2 x 1:2 input-output ratio, 4-output configuration, high-side N-Channel topology, 250mA current rating, 80mOhm Rds(on), 2.7V-5.5V load voltage range, and integrated fault protection (current limiting, over-temperature, UVLO).
