LP3907TLX-JSXS/NOPB Equivalent & Substitute Parts

Part Overview

The LP3907TLX-JSXS/NOPB is a quad-output PMIC (Power Management Integrated Circuit) from Texas Instruments that integrates two synchronous step-down (buck) regulators and two linear (LDO) regulators. This device is designed for multi-rail power distribution in portable and embedded applications requiring compact, integrated power management. The part is currently listed as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution of the LP3907TLX-JSXS/NOPB is determined by strict equivalence across the following critical parameters:

• Topology: Identical configuration of two synchronous buck regulators and two linear regulators
• Number of Outputs: Four independent regulated outputs
• Output Voltage and Current Ratings: Exact match across all four channels (1.2V/1A, 2.8V/600mA, 3.3V/300mA, and one additional output)
• Switching Frequency: 2.1MHz operation
• Supply Voltage Range: 2.8V to 5.5V input compatibility
• Operating Temperature Range: -40°C to 85°C
• Package: 25-WFBGA ball grid array
• Electrical Compliance: RoHS3 compliance and MSL Level 1

The LP3907TL-JSXS/NOPB meets all these criteria and is classified as a parametric equivalent. The primary distinction is product status: the original part is obsolete, while the substitute is active.

Parameter Comparison

Engineering Selection Recommendations

The LP3907TL-JSXS/NOPB is the direct parametric equivalent for the obsolete LP3907TLX-JSXS/NOPB. Both parts share identical electrical specifications, thermal ratings, and regulatory compliance certifications. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The packaging format difference (Tape & Reel for the substitute versus unspecified for the original) does not affect electrical or mechanical compatibility. Both parts are housed in the same 25-WFBGA package and are surface-mount compatible with identical pin configurations.

For new designs or redesigns of existing applications, the LP3907TL-JSXS/NOPB is the appropriate selection. For legacy system support where the original part number must be maintained, this substitute provides functional and form-factor equivalence.

Frequently Asked Questions (FAQ)

Q: Can the LP3907TL-JSXS/NOPB be used as a direct replacement for the LP3907TLX-JSXS/NOPB?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. The substitute is a parametric equivalent with active product status.

Q: What is the difference between the two part numbers?

A: The primary difference is product lifecycle status. The LP3907TLX-JSXS/NOPB is obsolete, while the LP3907TL-JSXS/NOPB is active. The electrical specifications, output configurations, and package are identical.

Q: Are there any PCB layout or design considerations when switching between these parts?

A: No design changes are required. Both parts use the same 25-WFBGA package with identical pinout and electrical characteristics. Existing PCB layouts and schematics are fully compatible.

Q: What is the packaging difference between these parts?

A: The substitute part is supplied in Tape & Reel (TR) format, which is standard for high-volume production. This does not affect the component itself or its performance.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the LP3907TLX-JSXS/NOPB and LP3907TL-JSXS/NOPB are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity ratings.

Q: Which part should be specified for new designs?

A: The LP3907TL-JSXS/NOPB should be specified for new designs due to its active product status and guaranteed long-term availability.
