LM5067MM-2 Hot Swap Controller Equivalent & Substitute Parts

Part Overview

The LM5067MM-2 is a negative hot swap controller designed for -48V applications, featuring a single channel with programmable circuit breaker, current limit, fault timeout, overvoltage protection (OVP), and undervoltage lockout (UVLO) functionality. The device operates in the -80V to -9V supply range and is housed in a 10-VSSOP package.

The LM5067MM-2 carries a "Not For New Designs" product status, indicating it is obsolete or transitioning out of production. Identifying equivalent and substitute parts is necessary for ongoing system support, maintenance, and design continuity where this controller is already deployed.

Substitute Part Grouping Explanation

Substitution eligibility for the LM5067MM-2 is determined by the following critical parameters:

• Single Channel Configuration: Substitute must have exactly 1 channel
• Negative Voltage Application: Substitute must support -48V operation within -80V to -9V supply range
• Programmable Feature Set: Substitute must include Circuit Breaker, Current Limit, Fault Timeout, OVP, and UVLO
• Auto Retry Capability: Substitute must include auto retry feature
• Package Compatibility: Substitute must use 10-VSSOP package or equivalent 10-TFSOP/10-MSOP footprint
• Operating Temperature Range: Substitute must support -40°C to 125°C minimum
• Supply Current: Substitute must operate at 2 mA supply current specification

The LM5067MM-2/NOPB meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The LM5067MM-2/NOPB is the direct equivalent substitute for the LM5067MM-2. Both parts share identical electrical specifications, package footprint, and functional capabilities. The primary distinction is product status: the LM5067MM-2 is marked "Not For New Designs," while the LM5067MM-2/NOPB maintains "Active" status, indicating ongoing manufacturer support and availability.

For applications currently using the LM5067MM-2, the LM5067MM-2/NOPB provides functional continuity with improved supply chain stability. Both parts comply with identical export classifications (EAR99) and tariff codes (8542.39.0001), ensuring regulatory consistency in deployment.

Frequently Asked Questions (FAQ)

Q: Can the LM5067MM-2/NOPB be used as a direct replacement for the LM5067MM-2?

A: Yes. The LM5067MM-2/NOPB is a direct equivalent. Both parts have identical electrical specifications, package footprint (10-VSSOP), supply voltage range (-80V to -9V), operating temperature range (-40°C to 125°C), and programmable feature sets (Circuit Breaker, Current Limit, Fault Timeout, OVP, UVLO).

Q: What does the "/NOPB" suffix indicate?

A: The "/NOPB" suffix indicates "No Plumbum" (lead-free) packaging. This denotes RoHS compliance in the manufacturing process. Verify your application's RoHS requirements before selection.

Q: Are there any package compatibility concerns?

A: No. Both parts use the 10-VSSOP package with identical 0.118" (3.00mm) width. The footprint is compatible with existing PCB designs without layout modifications.

Q: What is the significance of the "Not For New Designs" status on the LM5067MM-2?

A: This status indicates the part is obsolete or in end-of-life phase. Existing designs using this part should transition to the LM5067MM-2/NOPB to ensure long-term supply availability and manufacturer support.

Q: Are the supply current specifications identical?

A: Yes. Both parts operate at 2 mA supply current, ensuring equivalent power consumption in -48V hot swap applications.

Q: Do both parts support the same programmable features?

A: Yes. Both the LM5067MM-2 and LM5067MM-2/NOPB include programmable Circuit Breaker, Current Limit, Fault Timeout, OVP, and UVLO, with Auto Retry capability.
