TPS2086D Equivalent & Substitute Parts

Part Overview

The TPS2086D is a Power Management Integrated Circuit (PMIC) manufactured by Texas Instruments, classified as a Power Switch/Driver with N-Channel output configuration. This component functions as a high-side N-channel power switch with 1:1 input-to-output ratio and integrated fault protection mechanisms. The TPS2086D is currently listed as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPS2086D is determined by strict parametric equivalence across the following critical criteria:

Electrical Parameters (Must Match):

• Number of Outputs: 4
• Output Configuration: High Side
• Output Type: N-Channel
• Voltage - Load: 2.7V ~ 5.5V
• Current - Output (Max): 500mA
• Rds On (Typ): 80mOhm
• Interface: On/Off
• Input Type: Non-Inverting
• Features: Status Flag
• Fault Protection: Current Limiting (Fixed), Over Temperature, UVLO
• Operating Temperature: 0°C ~ 125°C (TJ)

Mechanical Parameters (Must Match):

• Mounting Type: Surface Mount
• Package / Case: 16-SOIC (0.154", 3.90mm Width)

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The TPS2085D and TPS2087D meet all specified electrical, mechanical, and compliance parameters and are classified as parametric equivalents. Both substitute parts are manufactured by Texas Instruments and maintain active product status, providing procurement continuity for the obsolete TPS2086D.

Parameter Comparison

Engineering Selection Recommendations

TPS2085D is an active product offering full parametric equivalence to the TPS2086D. This substitute part provides immediate procurement availability and ongoing manufacturer support. The TPS2085D is supplied in Tube packaging and maintains identical electrical specifications, fault protection architecture, and thermal operating range.

TPS2087D is an active product offering full parametric equivalence to the TPS2086D. This substitute part provides immediate procurement availability and ongoing manufacturer support. The TPS2087D is supplied in Tube packaging and maintains identical electrical specifications, fault protection architecture, and thermal operating range.

Both substitute parts satisfy ROHS3 compliance requirements and MSL Level 1 moisture sensitivity specifications, ensuring compatibility with standard manufacturing and storage protocols. Selection between TPS2085D and TPS2087D may be based on inventory availability and procurement lead times, as both parts are functionally and mechanically interchangeable with the obsolete TPS2086D.

Frequently Asked Questions (FAQ)

Q: Can TPS2085D and TPS2087D be used interchangeably with TPS2086D?

A: Yes. Both TPS2085D and TPS2087D are parametric equivalents to TPS2086D. All three parts share identical electrical specifications including 4-output high-side N-channel configuration, 500mA maximum output current, 80mOhm typical on-resistance, and identical fault protection features (current limiting, over-temperature, and UVLO). Package and mounting specifications are identical (16-SOIC surface mount). PCB layout and schematic integration require no modification.

Q: What is the primary difference between TPS2086D, TPS2085D, and TPS2087D?

A: The primary difference is product status. TPS2086D is obsolete, while TPS2085D and TPS2087D are active products. All electrical and mechanical parameters are identical. Packaging format differs only in supply method (TPS2086D was supplied in standard packaging; TPS2085D and TPS2087D are supplied in Tube packaging).

Q: Are there any compliance or certification differences?

A: No. All three parts maintain ROHS3 compliance and MSL Level 1 moisture sensitivity specifications. Regulatory classifications (ECCN: EAR99, HTSUS: 8542.39.0001) are identical.

Q: Can existing inventory of TPS2086D be replaced with TPS2085D or TPS2087D in production?

A: Yes. Since both substitute parts are parametric equivalents with identical package specifications, direct replacement in production is supported without PCB redesign or functional testing modifications.

Q: Which substitute part should be selected for new designs?

A: Either TPS2085D or TPS2087D is appropriate for new designs. Selection should be based on current inventory availability and supplier lead times, as both parts are functionally and mechanically identical.
