Substitute Part Grouping Explanation

Substitution of the LP5952TLX-1.3/NOPB is determined by strict equivalence across the following critical parameters:

• Output voltage specification: 1.3V fixed
• Output current capability: 350mA minimum
• Input voltage maximum rating: 4.5V
• Voltage dropout performance: 0.2V @ 350mA
• Package form factor: 5-DSBGA (1.41x1.08)
• Protection feature set: Over-current, over-temperature, short-circuit, and UVLO
• Operating temperature range: -40°C ~ 85°C
• Mounting configuration: Surface mount

The LP5952TL-1.3/NOPB meets all these criteria and qualifies as a parametric equivalent. The primary distinction between the main part and substitute is product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The LP5952TL-1.3/NOPB is the direct parametric equivalent for the obsolete LP5952TLX-1.3/NOPB. Both parts share identical electrical specifications, thermal performance, and protection characteristics. The substitute part maintains active product status with Texas Instruments, ensuring long-term availability and supply chain continuity.

The primary difference is packaging configuration: the main part is supplied in bulk format, while the substitute is available in Tape & Reel (TR) configuration. Both parts are ROHS3 compliant and carry identical regulatory certifications (REACH Unaffected, ECCN EAR99, HTSUS 8542.39.0001).

For new designs or production transitions, the LP5952TL-1.3/NOPB is the recommended selection due to its active status and standard tape-and-reel packaging, which aligns with modern manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can LP5952TL-1.3/NOPB directly replace LP5952TLX-1.3/NOPB in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. The 5-DSBGA package footprint, pinout, and electrical performance are equivalent. No circuit modifications are required.

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

A: The primary difference is product status and packaging format. The LP5952TLX-1.3/NOPB is obsolete and supplied in bulk. The LP5952TL-1.3/NOPB is active and supplied in Tape & Reel (TR) configuration, which is standard for automated assembly processes.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical RoHS3 compliance, REACH status, and regulatory classifications. They are fully interchangeable from a compliance perspective.

Q: What is the 5-DSBGA package specification?

A: The 5-DSBGA is a ball grid array package with dimensions of 1.41mm × 1.08mm. This is a surface-mount package suitable for high-density applications requiring minimal board space.

Q: Is the substitute part available in higher quantities?

A: Yes. The LP5952TL-1.3/NOPB has 1843 pieces in stock compared to 871 pieces for the obsolete variant, providing better supply availability.
