Substitute Part Grouping Explanation

Substitution eligibility for the TPIC44L01DB is determined by strict equivalence across the following critical parameters:

• Driven Configuration: Low-Side
• Number of Drivers: 4
• Gate Type: N-Channel, P-Channel MOSFET
• Voltage - Supply: 4.5V ~ 5.5V
• Current - Peak Output (Source, Sink): 1.2mA, 1.2mA
• Input Type: Non-Inverting
• Rise / Fall Time (Typ): 4.6µs, 3µs
• Operating Temperature: -40°C ~ 150°C (TJ)
• Package / Case: 24-SSOP (0.209", 5.30mm Width)

The TPIC44L02DB meets all substitution criteria and is identified as the manufacturer-recommended equivalent part. Both devices share identical electrical specifications, thermal operating range, and physical packaging, enabling direct functional replacement in existing designs.

Parameter Comparison

Engineering Selection Recommendations

The TPIC44L02DB is the qualified substitute for the obsolete TPIC44L01DB. Both parts maintain identical electrical and thermal specifications, ensuring functional compatibility in existing circuit designs without modification.

The TPIC44L02DB carries Last Time Buy status, indicating limited availability. Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component procurement.

Selection between these parts should be based on current supply chain availability and project timeline requirements. The TPIC44L02DB is the manufacturer-recommended path forward for new designs and ongoing production support.

Frequently Asked Questions (FAQ)

Q: Can the TPIC44L02DB directly replace the TPIC44L01DB in existing designs?

A: Yes. The TPIC44L02DB is electrically and mechanically equivalent to the TPIC44L01DB. No circuit modifications or PCB layout changes are required for substitution.

Q: Are there differences in packaging between these parts?

A: Both parts use the 24-SSOP package with identical physical dimensions (0.209", 5.30mm Width). Packaging compatibility is confirmed.

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

A: The TPIC44L01DB is obsolete and no longer manufactured. The TPIC44L02DB is in Last Time Buy status, meaning production is ending but limited inventory remains available. For new designs, the TPIC44L02DB should be specified.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the TPIC44L01DB and TPIC44L02DB are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What are the critical electrical parameters that define substitution eligibility?

A: Substitution is based on matching supply voltage range (4.5V ~ 5.5V), peak output current (1.2mA source and sink), rise/fall time specifications (4.6µs, 3µs), operating temperature range (-40°C ~ 150°C), and non-inverting input configuration across four independent low-side driver channels.
