LM3880MF-2AE-P Equivalent & Substitute Parts

Part Overview

The LM3880MF-2AE-P is a Power Supply Controller and Power Supply Sequencer manufactured by Texas Instruments, designed for surface mount applications in SOT-23-6 packaging. This device operates within a supply voltage range of 2.7V to 5.5V and draws a maximum supply current of 25 µA, making it suitable for low-power sequencing applications. The component is classified as Active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Alternative equivalent parts may be required due to inventory constraints, application-specific packaging preferences, or supply chain considerations.

Substitute Part Grouping Explanation

Substitution of the LM3880MF-2AE-P is determined by functional equivalence within the Power Management (PMIC) category, specifically for power supply sequencing and control applications. The primary substitute identified is the S-8424AAAFT-TB-U manufactured by ABLIC Inc.

Substitution Logic:

The S-8424AAAFT-TB-U qualifies as a functional equivalent based on the following criteria:

• Functional Category: Both devices operate as Power Supply Controllers within the PMIC classification
• Application Alignment: Both support power supply control and sequencing functions
• Surface Mount Technology: Both utilize surface mount construction for PCB integration
• RoHS Compliance: Both meet ROHS3 compliance requirements
• Moisture Sensitivity: Both carry MSL 1 rating (Unlimited)
• Active Product Status: Both are classified as Active products with ongoing manufacturer support

Key Differentiating Parameters:

• Package format differs (SOT-23-6 versus 8-TSSOP)
• Supply voltage input range differs (2.7V-5.5V versus 1.7V-16V)
• Operating temperature maximum differs (-40°C to 125°C versus -40°C to 85°C)
• Packaging format differs (component form versus Tape & Reel)

Engineering Selection Recommendations

LM3880MF-2AE-P Selection Criteria:

Select the LM3880MF-2AE-P when the application requires:

• SOT-23-6 package footprint compatibility with existing PCB designs
• Supply voltage operation strictly within 2.7V to 5.5V range
• Operating temperature performance up to 125°C junction temperature
• Established Texas Instruments component qualification in the design

S-8424AAAFT-TB-U Selection Criteria:

Select the S-8424AAAFT-TB-U when the application requires:

• 8-TSSOP package footprint compatibility
• Extended input voltage range from 1.7V to 16V for broader supply compatibility
• Tape & Reel packaging format for automated assembly processes
• ABLIC Inc. component qualification in the design
• Operating temperature performance up to 85°C is acceptable

Both parts maintain Active product status and ROHS3 compliance, ensuring long-term availability and regulatory conformance. Selection between these parts depends on package footprint requirements, voltage range specifications, and temperature operating range constraints specific to the application.

Frequently Asked Questions (FAQ)

Q: Can the S-8424AAAFT-TB-U directly replace the LM3880MF-2AE-P on an existing PCB?

A: Direct PCB replacement is not possible due to package differences. The LM3880MF-2AE-P uses SOT-23-6 packaging while the S-8424AAAFT-TB-U uses 8-TSSOP packaging. These packages have different pin counts, footprints, and pinout configurations. PCB redesign and re-layout are required for substitution.

Q: What are the voltage compatibility considerations between these parts?

A: The LM3880MF-2AE-P operates with supply voltage from 2.7V to 5.5V. The S-8424AAAFT-TB-U accepts input voltage from 1.7V to 16V. If your application operates within the 2.7V to 5.5V range, both parts are compatible. If your application requires operation below 2.7V or above 5.5V, only the S-8424AAAFT-TB-U is suitable.

Q: Are there temperature operating range limitations when substituting?

A: Yes. The LM3880MF-2AE-P operates to 125°C junction temperature, while the S-8424AAAFT-TB-U operates to 85°C. If your application requires sustained operation above 85°C, the LM3880MF-2AE-P is the only suitable option among these two parts.

Q: Do both parts meet the same regulatory compliance standards?

A: Both the LM3880MF-2AE-P and S-8424AAAFT-TB-U are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings. Both are classified as Active products. Regulatory compliance is equivalent between the two parts.

Q: What packaging format differences exist between these parts?

A: The LM3880MF-2AE-P is supplied as individual components in standard packaging. The S-8424AAAFT-TB-U is supplied in Tape & Reel (TR) format, which is optimized for automated pick-and-place assembly processes. Tape & Reel format is standard for high-volume manufacturing but requires compatible handling equipment.

Q: How do I determine which part is appropriate for my application?

A: Evaluate your application against these criteria: (1) Required package footprint and pin count compatibility with your PCB design; (2) Supply voltage operating range requirements; (3) Maximum junction temperature requirements; (4) Assembly process requirements (manual versus automated). Match your application requirements to the parameter specifications of each part to determine suitability.
