LM10504TME/NOPB Equivalent & Substitute Parts

Part Overview

The LM10504TME/NOPB is a Solid State Drives (SSD) Power Management Integrated Circuit (PMIC) manufactured by Texas Instruments. This device integrates a triple buck converter with low-dropout (LDO) regulator functionality in a 34-µSMD (2.82x2.82) package. The part is currently classified as Not For New Designs, indicating it has reached end-of-life status. Finding equivalent or substitute parts is necessary for ongoing system support, legacy design maintenance, and inventory replenishment where the original part is no longer available or economically viable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LM10504TME/NOPB is determined by the following critical parameters:

• Voltage Supply Range: Both main and substitute parts must operate within 3V ~ 5.5V
• Operating Temperature Range: Compatibility requires -30°C ~ 85°C operation
• Mounting Type: Surface Mount technology is required for PCB integration
• RoHS & Environmental Compliance: ROHS3 compliance and REACH unaffected status ensure regulatory alignment
• Package Compatibility: The substitute part must be compatible with the application's thermal, electrical, and mechanical requirements
• Functional Category: Power Management (PMIC) classification for SSD applications

The LM10502TLX/NOPB is identified as a manufacturer-recommended substitute. While it operates in the same voltage and temperature ranges with identical compliance certifications, it features a different package type (25-DSBGA versus 34-µSMD) and reduced supply current (60µA versus 15µA). These differences require design-level evaluation for PCB layout and thermal management compatibility.

Parameter Comparison

Engineering Selection Recommendations

The LM10502TLX/NOPB is the manufacturer-recommended substitute for the LM10504TME/NOPB. Both parts maintain identical voltage supply ranges (3V ~ 5.5V) and operating temperature specifications (-30°C ~ 85°C), ensuring functional compatibility in the specified operating environment.

Key considerations for selection:

• Product Status: The LM10502TLX/NOPB carries Active product status, ensuring continued availability and manufacturing support, whereas the LM10504TME/NOPB is Not For New Designs.
• Regulatory Compliance: Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
• Supply Current Difference: The substitute part draws 60µA compared to the main part's 15µA. This increased quiescent current must be evaluated against system power budget constraints.
• Package Transition: The change from 34-µSMD to 25-DSBGA requires PCB layout redesign and thermal management reassessment.

Frequently Asked Questions (FAQ)

Q: Can the LM10502TLX/NOPB be used as a direct drop-in replacement for the LM10504TME/NOPB?

A: No. While both parts share identical voltage supply ranges and operating temperature specifications, the package types differ (34-µSMD versus 25-DSBGA). PCB layout modifications are required. Additionally, the increased supply current (60µA versus 15µA) must be evaluated for system power consumption impact.

Q: What are the critical parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: voltage supply range (3V ~ 5.5V), operating temperature range (-30°C ~ 85°C), mounting type (Surface Mount), regulatory compliance (ROHS3, REACH unaffected), and functional category (Power Management PMIC for SSD applications).

Q: Why does the LM10502TLX/NOPB have higher supply current than the LM10504TME/NOPB?

A: The supply current difference (60µA versus 15µA) reflects different internal circuit architectures and functional integration. The LM10502TLX/NOPB is a single buck regulator, whereas the LM10504TME/NOPB integrates triple buck converters with LDO functionality, accounting for the lower quiescent current specification.

Q: Are both parts suitable for new SSD designs?

A: The LM10504TME/NOPB is classified as Not For New Designs. The LM10502TLX/NOPB carries Active product status and is suitable for new designs. For legacy system support or existing inventory management, the LM10504TME/NOPB remains available in limited quantities.

Q: What compliance certifications apply to both parts?

A: Both the LM10504TME/NOPB and LM10502TLX/NOPB are ROHS3 compliant and REACH unaffected. Both carry Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity constraints during storage and handling.
