TPS61236RWLR Equivalent & Substitute Parts

Part Overview

The TPS61236RWLR is a boost switching regulator IC from Texas Instruments designed for positive adjustable voltage regulation. It delivers 6.5A output current with a single adjustable output and operates across an input voltage range of 2.3V to 4.9V, producing output voltages from 2.9V to 5.5V. The device features synchronous rectification and operates at 1MHz switching frequency in a 9-VFQFN surface mount package.

The TPS61236RWLR is classified as obsolete. Locating equivalent substitute parts is necessary to support ongoing production requirements, maintenance operations, and system redesigns where this component is specified.

Substitute Part Grouping Explanation

Substitution of the TPS61236RWLR is determined by strict equivalence across the following critical parameters:

• Topology: Boost switching regulator
• Output configuration: Positive adjustable
• Input voltage range: 2.3V to 4.9V
• Output voltage range: 2.9V to 5.5V
• Output current: 6.5A (Switch)
• Switching frequency: 1MHz
• Synchronous rectification: Present
• Package: 9-VFQFN (2.5x2.5mm)
• Surface mount compatibility

The TPS61236PRWLR meets all electrical and mechanical substitution criteria. Both parts share identical base product number (TPS61236), electrical specifications, and package configuration. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The TPS61236PRWLR is a direct electrical and mechanical substitute for the TPS61236RWLR. Both devices are manufactured by Texas Instruments and comply with ROHS3 and REACH requirements.

The TPS61236PRWLR carries active product status, ensuring continued availability and manufacturing support. The substitute part features improved moisture sensitivity classification (MSL 1 versus MSL 2) and extended operating temperature range (junction temperature to 125°C versus ambient to 85°C), providing enhanced reliability margins in production environments.

Packaging format differs: the TPS61236PRWLR is supplied in Cut Tape (CT) and Digi-Reel® formats, whereas the obsolete TPS61236RWLR was supplied in standard packaging. This distinction affects procurement and assembly workflows but does not impact electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Are the TPS61236RWLR and TPS61236PRWLR electrically identical?

A: Yes. Both devices share identical electrical specifications across input voltage range (2.3V to 4.9V), output voltage range (2.9V to 5.5V), output current (6.5A), switching frequency (1MHz), and synchronous rectification capability.

Q: Can the TPS61236PRWLR be used as a direct replacement in existing PCB designs?

A: Yes. Both parts use the 9-VFQFN package with identical pinout and footprint (2.5x2.5mm). No PCB redesign is required.

Q: What is the significance of the different operating temperature ranges?

A: The TPS61236RWLR specifies ambient temperature (TA) to 85°C, while the TPS61236PRWLR specifies junction temperature (TJ) to 125°C. The TPS61236PRWLR provides a wider thermal operating margin and is suitable for higher-temperature applications.

Q: Why does the TPS61236PRWLR have a lower Moisture Sensitivity Level (MSL)?

A: MSL 1 (Unlimited shelf life) versus MSL 2 (1-year shelf life) indicates improved moisture resistance in the TPS61236PRWLR. This reduces risk of moisture-induced failures during storage and assembly.

Q: What packaging formats are available for the substitute part?

A: The TPS61236PRWLR is supplied in Cut Tape (CT) and Digi-Reel® formats, supporting both manual and automated assembly workflows.

Q: Are there any compliance or certification differences?

A: Both parts maintain ROHS3 compliance and REACH unaffected status. No compliance barriers exist for substitution.
