LM5122ZPWPR Equivalent & Substitute Parts

Part Overview

The LM5122ZPWPR is a wide input range boost controller IC manufactured by Texas Instruments, designed for step-up DC-DC conversion applications. This active product operates across a 4.5V to 65V supply voltage range with switching frequencies up to 1MHz and supports synchronous rectification with clock synchronization capabilities. The device is housed in a 24-PowerTSSOP package and is ROHS3 compliant with MSL 3 moisture sensitivity rating.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same base product family, allowing for component interchangeability in boost regulator circuit designs while accommodating different packaging and inventory availability requirements.

Substitute Part Grouping Explanation

Substitute parts for the LM5122ZPWPR are identified based on strict parametric equivalence within the LM5122 base product family. All substitute candidates maintain identical electrical specifications including the 4.5V to 65V input voltage range, 1MHz maximum switching frequency, 100% duty cycle capability, and single-phase boost topology with synchronous rectification and clock sync features.

The primary differentiator among substitute parts is packaging configuration. The main part (LM5122ZPWPR) is supplied in Cut Tape (CT) and Digi-Reel® packaging, while substitute parts are available in standard Tape & Reel (TR) packaging. Both packaging types utilize the same 24-PowerTSSOP physical package with identical pin configurations and thermal characteristics.

All parts share the same base product number (LM5122), product status (Active), operating temperature range (-40°C to 125°C), RoHS3 compliance, MSL 3 rating, and regulatory classifications (EAR99, HTSUS 8542.39.0001).

Parameter Comparison

Engineering Selection Recommendations

All three parts are active products from Texas Instruments with identical electrical and thermal specifications, making them functionally interchangeable in boost regulator applications. Selection between LM5122ZPWPR and its substitutes should be based on packaging requirements and inventory availability.

The LM5122ZPWPR in Cut Tape and Digi-Reel® packaging is suitable for lower-volume applications or manual assembly processes. The LM5122ZAPWPT and LM5122ZPWPT, both supplied in standard Tape & Reel packaging, are optimized for high-volume automated assembly operations.

All parts maintain ROHS3 compliance, MSL 3 moisture sensitivity rating, and identical regulatory classifications. No additional qualification or testing is required when substituting between these parts, provided the physical package footprint and tape reel specifications are compatible with the assembly process.

Frequently Asked Questions (FAQ)

Q: Can LM5122ZAPWPT and LM5122ZPWPT be used interchangeably with LM5122ZPWPR?

A: Yes. All three parts share identical electrical specifications, operating parameters, and physical package dimensions (24-PowerTSSOP). The only difference is packaging format: the main part uses Cut Tape/Digi-Reel, while the substitutes use standard Tape & Reel. Pin configuration and thermal performance are identical.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) and Digi-Reel® packaging are used for lower-volume or manual assembly applications, while Tape & Reel (TR) packaging is standard for high-volume automated pick-and-place assembly. The components themselves are identical; only the delivery format differs.

Q: Are there any compliance or certification differences between these parts?

A: No. All three parts are ROHS3 compliant, carry MSL 3 moisture sensitivity rating, and share identical REACH, ECCN, and HTSUS classifications. No additional compliance documentation is required when substituting between them.

Q: What are the key electrical parameters that define substitutability for the LM5122 family?

A: Substitutability is determined by: input voltage range (4.5V to 65V), switching frequency capability (up to 1MHz), duty cycle (100%), output topology (single-phase boost), synchronous rectification support, clock synchronization capability, and operating temperature range (-40°C to 125°C). All three parts maintain these specifications identically.

Q: Can these parts be used in applications requiring wide input voltage ranges?

A: Yes. All three parts support the full 4.5V to 65V input voltage range with 100% duty cycle capability, making them suitable for applications with wide input voltage variation or battery-powered systems with significant voltage swing.
