TPIC2603NE Equivalent & Substitute Parts

Part Overview

The TPIC2603NE is a Power Switch/Driver IC with 1:6 output configuration, rated for 350mA maximum output current. This component functions as a low-side power driver with integrated fault protection including current limiting, open load detection, over-temperature, and over-voltage protection. The device operates across a load voltage range of 5.5V to 25V with a supply voltage of 4.5V to 5.5V.

The TPIC2603NE is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs and system updates.

Substitute Part Grouping Explanation

Substitution eligibility for the TPIC2603NE is determined by strict equivalence across the following critical parameters:

• Number of Outputs: 6 channels
• Input:Output Ratio: 1:6
• Output Configuration: Low Side topology
• Voltage - Load: 5.5V ~ 25V range
• Voltage - Supply: 4.5V ~ 5.5V range
• Current - Output (Max): 350mA
• Rds On (Typ): 1.7Ohm
• Fault Protection: Current Limiting (Fixed), Open Load Detect, Over Temperature, Over Voltage
• Operating Temperature: -40°C ~ 125°C (TA)
• Interface: Serial

The TPIC2603DW meets all electrical and functional requirements for direct substitution. The primary difference is packaging format: the TPIC2603NE uses Through Hole mounting (20-DIP), while the TPIC2603DW uses Surface Mount technology (24-SOIC). Both devices share the same base product number (TPIC2603) and are manufactured by Texas Instruments.

Parameter Comparison

Engineering Selection Recommendations

The TPIC2603DW is the direct electrical equivalent to the TPIC2603NE. Both devices are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

The TPIC2603NE is obsolete; the TPIC2603DW is active production. Selection of the TPIC2603DW is appropriate for new designs and production continuity. The substitution requires PCB layout modification to accommodate the transition from Through Hole (20-DIP) to Surface Mount (24-SOIC) packaging. No electrical redesign is necessary.

Frequently Asked Questions (FAQ)

Q: Can the TPIC2603DW directly replace the TPIC2603NE without circuit modification?

A: Electrical functionality is identical. PCB layout modification is required due to different mounting technologies: the TPIC2603NE uses Through Hole mounting while the TPIC2603DW uses Surface Mount technology. Pin configuration differs between the 20-DIP and 24-SOIC packages.

Q: Are there any electrical performance differences between these parts?

A: No. Both devices share identical electrical specifications: 350mA maximum output current, 1.7Ohm typical on-resistance, 5.5V to 25V load voltage range, 4.5V to 5.5V supply voltage range, and identical fault protection features.

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

A: The TPIC2603NE is obsolete and no longer manufactured. The TPIC2603DW is in active production, ensuring long-term availability and supply chain reliability for new applications.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the TPIC2603NE and TPIC2603DW are ROHS3 compliant and REACH unaffected.

Q: What packaging considerations apply to this substitution?

A: The TPIC2603NE uses 20-DIP Through Hole packaging (0.300", 7.62mm). The TPIC2603DW uses 24-SOIC Surface Mount packaging (0.295", 7.50mm Width). PCB redesign is necessary to accommodate the different mounting method and pin layout.
