LM2832ZMY Equivalent & Substitute Parts

Part Overview

The LM2832ZMY is a buck switching regulator IC from Texas Instruments designed for positive adjustable output applications. It delivers 2A output current with an adjustable output voltage range from 0.6V to 4.5V, operating from a 3V to 5.5V input supply. The device is housed in an 8-TSSOP/8-MSOP package with exposed pad and operates across the industrial temperature range of -40°C to 125°C.

The LM2832ZMY is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term product availability for applications currently using this regulator.

Substitute Part Grouping Explanation

Substitution of the LM2832ZMY is determined by strict equivalence across the following critical parameters:

  • Functional topology: Buck (step-down) switching regulator
  • Output configuration: Positive adjustable output
  • Electrical specifications: Input voltage 3V–5.5V, output voltage 0.6V–4.5V, 2A output current
  • Switching frequency: 3MHz
  • Package compatibility: 8-TSSOP/8-MSOP with exposed pad (8-HVSSOP supplier package)
  • Temperature range: -40°C to 125°C
  • Mounting type: Surface mount

The LM2832ZMY/NOPB is identified as a direct substitute based on identical electrical and mechanical specifications. The primary distinction is product status and packaging format.

Engineering Selection Recommendations

The LM2832ZMY/NOPB is the direct substitute for the obsolete LM2832ZMY. Both parts share identical electrical and mechanical specifications, ensuring pin-for-pin and functional compatibility.

The LM2832ZMY/NOPB offers two significant advantages:

  • Active product status: Ensures ongoing availability and manufacturer support
  • ROHS3 compliance: Meets current environmental and regulatory requirements, whereas the original LM2832ZMY is RoHS non-compliant

The LM2832ZMY/NOPB is supplied in Tape & Reel (TR) packaging format, which is standard for production and automated assembly environments. The original LM2832ZMY was available in bulk packaging.

For new designs or production transitions, the LM2832ZMY/NOPB is the appropriate selection. For existing inventory management or legacy system support, the electrical equivalence between both parts permits direct substitution without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the LM2832ZMY/NOPB replace the LM2832ZMY in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. The LM2832ZMY/NOPB is a direct substitute with no circuit modifications required.

Q: What is the difference between LM2832ZMY and LM2832ZMY/NOPB?

A: The primary differences are product status, compliance certification, and packaging format. The LM2832ZMY is obsolete and RoHS non-compliant, supplied in bulk. The LM2832ZMY/NOPB is active, ROHS3 compliant, and supplied in Tape & Reel format. Electrical and mechanical specifications are identical.

Q: Is the 8-HVSSOP package compatible with the 8-TSSOP/8-MSOP footprint?

A: Yes. The 8-HVSSOP is the supplier device package designation for the 8-TSSOP/8-MSOP (0.118", 3.00mm Width) with exposed pad. The physical footprint and pin configuration are identical.

Q: What is the significance of the /NOPB suffix?

A: The /NOPB suffix indicates "No Plumbum" (lead-free) and is associated with RoHS compliance. This designation reflects the manufacturing process and environmental compliance status of the part.

Q: Can I use the LM2832ZMY/NOPB in applications requiring RoHS compliance?

A: Yes. The LM2832ZMY/NOPB is ROHS3 compliant and suitable for applications with RoHS requirements. The original LM2832ZMY is RoHS non-compliant.

Q: Are there any thermal or performance differences between the two parts?

A: No. Both parts operate across the same temperature range (-40°C to 125°C) and deliver identical electrical performance. Thermal characteristics and switching frequency are equivalent.
