Key Parameters

Substitute Part Grouping Explanation

Substitution of the LM5069MMX-2 is determined by strict equivalence across the following parameters:

• Base product number (LM5069)
• Functional type (Hot Swap Controller)
• Channel configuration (1 Channel)
• Supply voltage range (9V ~ 80V)
• Operating temperature range (-40°C ~ 125°C)
• Package type (10-TFSOP, 10-MSOP)
• Programmable feature set (Current Limit, Fault Timeout, OVP, UVLO)
• Auto Retry capability

The LM5069MMX-2/NOPB qualifies as a direct substitute based on identical electrical specifications, package configuration, and functional capabilities. The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The LM5069MMX-2/NOPB is the direct functional equivalent for applications currently using the obsolete LM5069MMX-2. Both parts share identical electrical specifications, package dimensions, and programmable feature sets, ensuring pin-to-pin and functional compatibility.

The LM5069MMX-2/NOPB carries Active product status, ensuring long-term availability and manufacturing support. This part also meets ROHS3 compliance requirements, whereas the original LM5069MMX-2 is RoHS non-compliant. For new designs or systems requiring regulatory compliance, the LM5069MMX-2/NOPB is the appropriate selection.

Both parts maintain identical supply voltage ranges (9V ~ 80V), operating temperature specifications (-40°C ~ 125°C), and current supply characteristics (1.3 mA), confirming full electrical interchangeability.

Frequently Asked Questions (FAQ)

Q: Can the LM5069MMX-2/NOPB directly replace the LM5069MMX-2 in existing designs?

A: Yes. Both parts are functionally identical with matching pin configurations, electrical specifications, and package dimensions (10-TFSOP, 10-MSOP). No circuit modifications are required.

Q: What is the significance of the "/NOPB" suffix in the LM5069MMX-2/NOPB part number?

A: The "/NOPB" designation indicates the part is supplied in Cut Tape (CT) and Digi-Reel packaging formats without lead-free plating on the leads. This is a packaging and distribution specification that does not affect electrical performance or compatibility.

Q: Why is the original LM5069MMX-2 marked as Obsolete?

A: The LM5069MMX-2 has been discontinued by Texas Instruments. The LM5069MMX-2/NOPB remains in active production and is the recommended replacement for ongoing support and new applications.

Q: Are there compliance differences between these parts?

A: The LM5069MMX-2/NOPB meets ROHS3 compliance standards, while the original LM5069MMX-2 is RoHS non-compliant. Both maintain identical REACH and ECCN classifications. For applications requiring RoHS compliance, the LM5069MMX-2/NOPB is the appropriate choice.

Q: Do both parts support the same programmable features?

A: Yes. Both the LM5069MMX-2 and LM5069MMX-2/NOPB support identical programmable features: Current Limit, Fault Timeout, OVP (Overvoltage Protection), and UVLO (Undervoltage Lockout), with Auto Retry capability.

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

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