LM5069MMX-1 Equivalent & Substitute Parts

Part Overview

The LM5069MMX-1 is a Hot Swap Controller designed for general-purpose applications, featuring 1 channel with programmable current limit, fault timeout, overvoltage protection (OVP), and undervoltage lockout (UVLO). The device operates across a 9V to 80V supply voltage range and is housed in a 10-VSSOP package.

The LM5069MMX-1 is classified as obsolete. Locating direct equivalents becomes necessary for system redesigns, production continuity, or when original inventory is depleted. The substitute part maintains identical electrical and mechanical specifications while offering improved availability and compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LM5069MMX-1 is determined by the following criteria:

• Functional Type: Hot Swap Controller with identical channel count (1) and internal switch configuration (No)
• Electrical Specifications: Matching voltage supply range (9V ~ 80V), operating temperature range (-40°C ~ 125°C), and supply current (1.3 mA)
• Programmable Features: Identical feature set including Current Limit, Fault Timeout, OVP, and UVLO
• Package Compatibility: 10-VSSOP package with matching mechanical dimensions (10-TFSOP, 10-MSOP, 0.118", 3.00mm Width)
• Manufacturer: Texas Instruments

The substitute part LM5069MMX-1/NOPB meets all these criteria and is electrically and mechanically interchangeable.

Parameter Comparison

Engineering Selection Recommendations

The LM5069MMX-1/NOPB is the direct substitute for the obsolete LM5069MMX-1. Both parts are manufactured by Texas Instruments and share identical electrical and mechanical specifications across all functional parameters.

The primary distinction is product status and compliance:

• LM5069MMX-1: Obsolete status with RoHS non-compliant certification
• LM5069MMX-1/NOPB: Active product status with ROHS3 compliance

For new designs or production continuity, the LM5069MMX-1/NOPB is the appropriate selection. Both parts maintain REACH Unaffected status and EAR99 ECCN classification. The substitute part is available in Cut Tape (CT) and Digi-Reel® packaging formats with significantly higher inventory availability (100,300 pcs vs. 949 pcs).

Frequently Asked Questions (FAQ)

Q: Are LM5069MMX-1 and LM5069MMX-1/NOPB pin-for-pin compatible?

A: Yes. Both devices use the 10-VSSOP package with identical pin configuration, electrical characteristics, and functional behavior. Direct PCB substitution is possible without layout modifications.

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

A: The "/NOPB" designation indicates the part is supplied without plumbum (lead-free, RoHS3 compliant). The LM5069MMX-1 without this suffix is RoHS non-compliant.

Q: Can I use LM5069MMX-1/NOPB in existing designs originally specified for LM5069MMX-1?

A: Yes. The electrical and mechanical specifications are identical. The substitute part is a direct replacement suitable for both new production and field retrofits.

Q: Why is the original LM5069MMX-1 marked as obsolete?

A: Obsolescence typically results from manufacturer discontinuation decisions. The LM5069MMX-1/NOPB remains in active production and serves the same functional requirements.

Q: Are there packaging differences between the two parts?

A: The LM5069MMX-1 packaging format is not specified in available data. The LM5069MMX-1/NOPB is supplied in Cut Tape (CT) and Digi-Reel® formats. Both use the 10-VSSOP package with identical mechanical dimensions.

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

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
