Parameter Comparison

Engineering Selection Recommendations

The LP2966IMM-5050/NOPB serves as the direct parametric equivalent for the obsolete LP2966IMMX-5050. Both devices share identical electrical specifications, thermal characteristics, and package geometry, ensuring pin-for-pin and functional compatibility.

The LP2966IMM-5050/NOPB maintains active product status with Texas Instruments, providing long-term availability and supply chain stability. Both variants comply with ROHS3 and REACH requirements, with identical moisture sensitivity ratings and ECCN classifications.

Selection between these parts depends on packaging requirements. The LP2966IMM-5050/NOPB is supplied in Tape & Reel format, suitable for automated assembly processes. The original LP2966IMMX-5050 was supplied in tube packaging. Verify your assembly process compatibility with the available packaging format.

Frequently Asked Questions (FAQ)

Q: Can the LP2966IMM-5050/NOPB directly replace the LP2966IMMX-5050 in existing designs?

A: Yes. Both devices are electrically and mechanically identical. Pin configuration, electrical performance, and thermal characteristics are equivalent. The primary difference is product status and packaging format.

Q: What is the significance of the product status difference?

A: The LP2966IMMX-5050 is obsolete, indicating Texas Instruments no longer manufactures this variant. The LP2966IMM-5050/NOPB maintains active status, ensuring continued availability and manufacturing support.

Q: Does the Tape & Reel packaging affect circuit performance?

A: No. Tape & Reel packaging is a supply format for automated assembly. The component itself and its electrical characteristics remain unchanged. Verify your assembly equipment compatibility with this packaging format.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS3 compliance, REACH status, and moisture sensitivity ratings. Regulatory and environmental compliance requirements are equivalent.

Q: What parameters must remain constant for substitution?

A: Output voltage (5V fixed), output current (150mA), dual-regulator configuration, input voltage rating (7V max), dropout voltage (0.27V @ 150mA), package type (8-VSSOP), and operating temperature range (-40°C to 125°C) must all match exactly.
