LM2853MH-3.0 Equivalent & Substitute Parts

Part Overview

The LM2853MH-3.0 is a buck switching regulator IC from Texas Instruments' SIMPLE SWITCHER® series, designed for step-down voltage conversion with a fixed 3V output and 3A current capacity. This device operates across an input voltage range of 3V to 5.5V and features synchronous rectification for improved efficiency. The main part number LM2853MH-3.0 is classified as obsolete, making identification of active equivalent parts essential for new designs and ongoing production support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LM2853MH-3.0 is determined by strict equivalence across the following critical parameters:

• Output Voltage: Fixed 3V output
• Output Current: 3A continuous capability
• Input Voltage Range: 3V to 5.5V operation
• Switching Frequency: 550kHz topology
• Synchronous Rectification: Required feature
• Package Compatibility: 14-PowerTSSOP form factor
• Thermal Range: -40°C to 125°C operating specification

The substitute part LM2853MH-3.0/NOPB maintains identical electrical specifications and mechanical packaging, with the primary distinction being product status (active versus obsolete) and RoHS compliance certification level.

Engineering Selection Recommendations

The LM2853MH-3.0/NOPB is the direct active equivalent for the obsolete LM2853MH-3.0. Selection between these parts is determined by regulatory and compliance requirements:

For new designs and production requiring regulatory compliance: LM2853MH-3.0/NOPB is the appropriate choice, as it maintains active product status and ROHS3 compliance certification. This part is suitable for applications subject to RoHS directives and modern supply chain requirements.

For legacy system maintenance or non-regulated applications: The LM2853MH-3.0 remains functionally equivalent where RoHS compliance is not mandated. However, availability is limited to existing inventory (935 pcs), and long-term sourcing is not guaranteed due to obsolete status.

Both parts are electrically and mechanically identical across all specified parameters, ensuring direct substitution without circuit redesign or PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can LM2853MH-3.0/NOPB be used as a direct replacement for LM2853MH-3.0?

A: Yes. Both parts are electrically and mechanically identical. The LM2853MH-3.0/NOPB is the active equivalent with updated RoHS compliance certification. No circuit modifications or PCB changes are required for substitution.

Q: What is the difference between LM2853MH-3.0 and LM2853MH-3.0/NOPB?

A: The primary differences are product status (obsolete versus active) and RoHS compliance level (non-compliant versus ROHS3 compliant). Electrical specifications, output voltage, current rating, switching frequency, and package type are identical.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the 14-PowerTSSOP package with identical pinout and mechanical dimensions (0.173" width, 4.40mm). PCB footprints are directly compatible.

Q: Which part should be specified for new designs?

A: LM2853MH-3.0/NOPB should be specified for new designs. It is the active product with current manufacturing support and regulatory compliance certifications.

Q: What is the operating temperature range for both parts?

A: Both parts operate across -40°C to 125°C junction temperature (TJ), meeting industrial and extended temperature requirements.

Q: Are the input and output voltage specifications identical?

A: Yes. Both parts accept input voltage from 3V to 5.5V and provide a fixed 3V output at 3A continuous current capacity.
