LM5068MM-2 Equivalent & Substitute Parts

Part Overview

The LM5068MM-2 is a Hot Swap Controller designed for -48V applications, featuring a single channel with programmable circuit protection including current limiting, fault timeout, overvoltage protection (OVP), and undervoltage lockout (UVLO). The device is packaged in an 8-VSSOP surface mount package and operates across a -40°C to 105°C temperature range.

The LM5068MM-2 is currently discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LM5068MM-2 is determined by strict equivalence across the following critical parameters:

• Manufacturer and base product number (LM5068 series)
• Single-channel hot swap controller architecture
• -48V application support with -90V to -10V supply voltage range
• Identical operating temperature range (-40°C to 105°C)
• Identical supply current specification (820 µA)
• Surface mount packaging in 8-VSSOP configuration
• Identical feature set: Auto Retry, Turn On Voltage
• Identical programmable protection features: Circuit Breaker, Current Limit, Fault Timeout, OVP, UVLO

The LM5068MM-2/NOPB qualifies as a direct substitute based on complete parameter alignment across all electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The LM5068MM-2/NOPB is the direct substitute for the discontinued LM5068MM-2. Both parts are electrically and mechanically identical across all specified parameters. The primary distinction is product status and regulatory compliance.

The LM5068MM-2 is discontinued and carries RoHS non-compliant status. The LM5068MM-2/NOPB is currently active in production and meets ROHS3 compliance requirements. For new designs or production continuity, the LM5068MM-2/NOPB is the appropriate selection. The "/NOPB" suffix indicates lead-free plating, which aligns with modern manufacturing and environmental standards.

Both parts maintain identical electrical performance, supply voltage range, operating temperature specifications, and programmable protection features. Pin-to-pin compatibility and functional equivalence are complete.

Frequently Asked Questions (FAQ)

Q: Can the LM5068MM-2/NOPB be used as a direct replacement for the LM5068MM-2?

A: Yes. The LM5068MM-2/NOPB is electrically and mechanically identical to the LM5068MM-2. All electrical parameters, operating ranges, and programmable features are equivalent. The parts are pin-compatible and functionally interchangeable.

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

A: The "/NOPB" suffix designates lead-free plating on the device leads. This indicates compliance with RoHS3 standards and modern manufacturing requirements.

Q: Are there differences in RoHS compliance between these parts?

A: Yes. The LM5068MM-2 is RoHS non-compliant, while the LM5068MM-2/NOPB is ROHS3 compliant. For applications subject to RoHS requirements or environmental regulations, the LM5068MM-2/NOPB is the required selection.

Q: Is the packaging identical between the two parts?

A: Yes. Both parts use the 8-VSSOP surface mount package with identical dimensions (0.118", 3.00mm width). PCB layout and footprint compatibility are complete.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without moisture control requirements.

Q: Are the supply voltage and operating temperature ranges the same?

A: Yes. Both parts operate across -90V to -10V supply voltage and -40°C to 105°C operating temperature. Electrical performance is identical across all specified conditions.
