LM20134MH/NOPB Equivalent & Substitute Parts

Part Overview

The LM20134MH/NOPB is a buck switching regulator IC from Texas Instruments' PowerWise® series, designed for step-down voltage conversion applications. This positive adjustable regulator delivers 4A output current with an input voltage range of 2.95V to 5.5V and adjustable output from 0.8V to 4.68V. The device features synchronous rectification and operates across the industrial temperature range of -40°C to 125°C. As an active product with ROHS3 compliance and unlimited moisture sensitivity rating, substitute parts are identified based on identical electrical specifications and compatible packaging configurations.

Substitute Part Grouping Explanation

Substitution of the LM20134MH/NOPB is determined by strict equivalence across all electrical and mechanical parameters. The primary substitute identified is the LM20134MHX/NOPB, which maintains identical specifications for input voltage range, output voltage range, output current, switching frequency, synchronous rectification capability, operating temperature range, and package configuration. The only difference between these parts is the packaging format: the main part is supplied in Tube packaging, while the substitute is supplied in Tape & Reel (TR) format. Both parts share the same base product number (LM20134), manufacturer (Texas Instruments), and series designation (PowerWise®). Substitution is valid when the application requirements do not impose specific packaging or supply chain constraints.

Parameter Comparison

Engineering Selection Recommendations

Both the LM20134MH/NOPB and LM20134MHX/NOPB are active products from Texas Instruments with identical ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on supply chain and assembly process requirements. The LM20134MH/NOPB in Tube packaging is suitable for lower-volume applications or manual assembly workflows. The LM20134MHX/NOPB in Tape & Reel format is optimized for high-volume automated pick-and-place assembly operations. Both parts meet the same electrical and thermal specifications, ensuring functional equivalence in the application circuit.

Frequently Asked Questions (FAQ)

Q: Can LM20134MHX/NOPB replace LM20134MH/NOPB in production?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format only. LM20134MHX/NOPB (Tape & Reel) is suitable for automated assembly, while LM20134MH/NOPB (Tube) is suitable for manual or lower-volume assembly.

Q: Are there any performance differences between these parts?

A: No. Both parts share identical electrical specifications including input voltage range (2.95V–5.5V), output voltage range (0.8V–4.68V), output current (4A), switching frequency (410kHz), and operating temperature range (-40°C to 125°C).

Q: Do both parts fit the same PCB footprint?
