TPS65166RHAR Equivalent & Substitute Parts

Part Overview

The TPS65166RHAR is a Power Management IC (PMIC) designed for LCD TV and Monitor bias supply applications. This device operates as a TFT-LCD bias supply controller in a 40-VQFN surface mount package. The TPS65166RHAR is classified as obsolete, which necessitates identification of active equivalent parts for new designs and ongoing production requirements. Substitute parts must maintain functional compatibility within the specified electrical and mechanical parameters for LCD TV/Monitor applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPS65166RHAR is determined by the following critical parameters:

• Functional Application: Both parts must serve LCD TV/Monitor bias supply functions
• Voltage Supply Range: Substitute must operate within or encompass the original 8.5V ~ 14.7V range
• Operating Temperature Range: Substitute must support -40°C ~ 85°C operation
• Package Compatibility: Both parts use 40-pin QFN surface mount packages with 6x6mm footprints
• Regulatory Compliance: Both parts must maintain ROHS3 compliance and REACH unaffected status

The TPS65168RSBR meets these substitution criteria as an active product from the same manufacturer within the same product family, with compatible electrical specifications and package footprint.

Parameter Comparison

Engineering Selection Recommendations

The TPS65168RSBR is the manufacturer-recommended substitute for the obsolete TPS65166RHAR. Selection of the TPS65168RSBR is based on the following engineering factors:

• Product Status: The TPS65168RSBR maintains active product status, ensuring continued availability and manufacturing support from Texas Instruments
• Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements
• Electrical Compatibility: The TPS65168RSBR operates within the required voltage supply range (8.6V ~ 14.7V) and maintains the same operating temperature specification (-40°C ~ 85°C)
• Package Compatibility: Both devices use 40-pin QFN packages with identical 6x6mm footprints, supporting direct PCB layout compatibility
• Moisture Sensitivity: The TPS65168RSBR features improved moisture sensitivity level (MSL 2, 1 Year) compared to the original part (MSL 3, 168 Hours), providing enhanced reliability in storage and handling

Frequently Asked Questions (FAQ)

Q: Can the TPS65168RSBR be used as a direct replacement for the TPS65166RHAR?

A: The TPS65168RSBR is the manufacturer-recommended substitute. Both parts share identical operating temperature ranges, compatible voltage supply specifications, and matching 40-pin QFN package footprints. PCB layout modifications are not required for package compatibility.

Q: What is the difference between the 40-VQFN and 40-WQFN package designations?

A: Both designations refer to 40-pin Quad Flat No-Lead packages with 6x6mm dimensions. The letter designation (V vs. W) indicates minor variations in package construction specifications. Both packages are mechanically and electrically compatible for this application.

Q: Are there any voltage supply range differences between these parts?

A: The TPS65166RHAR operates at 8.5V ~ 14.7V, while the TPS65168RSBR operates at 8.6V ~ 14.7V. This 0.1V difference at the lower threshold does not affect compatibility in standard LCD TV/Monitor bias supply applications.

Q: What is the significance of the improved Moisture Sensitivity Level?

A: The TPS65168RSBR features MSL 2 (1 Year) compared to the original MSL 3 (168 Hours). This indicates improved moisture resistance during storage and handling, reducing the risk of moisture-related failures during assembly and deployment.

Q: Is the TPS65168RSBR suitable for new design implementations?

A: The TPS65168RSBR is classified as an active product with full manufacturing support from Texas Instruments. It is suitable for new designs requiring LCD TV/Monitor bias supply functionality within the specified electrical and environmental parameters.
