TPIC2603DWR Equivalent & Substitute Parts

Part Overview

The TPIC2603DWR is a Power Management Integrated Circuit (PMIC) manufactured by Texas Instruments, classified as a Power Switch/Driver with a 1:6 output configuration. This device functions as a low-side power driver capable of delivering up to 350mA per output across six independent channels, operating from a 4.5V to 5.5V supply with load voltage support up to 25V. The part is currently Active in product status with 3,168 units available in new original inventory. Alternative models become necessary when specific packaging formats, inventory availability, or supply chain constraints require substitution while maintaining identical electrical and mechanical performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

The TPIC2603DWRG4 qualifies as a parametric equivalent to the TPIC2603DWR based on identical electrical specifications and mechanical compatibility. Substitution is valid when the following criteria are met:

• Identical number of outputs (6 channels)
• Matching input-to-output ratio (1:6)
• Identical output configuration (Low Side)
• Matching voltage specifications: Load voltage 5.5V ~ 25V, Supply voltage 4.5V ~ 5.5V
• Identical maximum output current (350mA per channel)
• Matching on-resistance specification (1.7Ohm typical)
• Identical package format (24-SOIC with 0.295" / 7.50mm width)
• Matching operating temperature range (-40°C ~ 125°C)
• Identical fault protection features (Current Limiting, Open Load Detect, Over Temperature, Over Voltage)

The primary distinction between these parts is packaging format: the main part is supplied in Tape & Reel (TR) format, while the substitute is available in Cut Tape (CT) & Digi-Reel® format. Both maintain identical electrical performance and physical dimensions.

Engineering Selection Recommendations

The TPIC2603DWR is the preferred selection for new designs and ongoing production due to its Active product status and continuous availability. The TPIC2603DWRG4 remains electrically and mechanically equivalent but carries Discontinued at DiGi Electronics status, limiting its suitability for long-term supply chain planning.

Selection between these parts should be based on:

• Packaging requirements: Choose TPIC2603DWR for standard Tape & Reel applications; TPIC2603DWRG4 for Cut Tape or Digi-Reel® format requirements
• Inventory availability: TPIC2603DWR offers 3,168 units in stock; TPIC2603DWRG4 offers 5,189 units but with discontinued status
• Compliance requirements: Both parts maintain ROHS3 compliance and REACH Unaffected status, suitable for regulated applications
• Long-term sourcing: TPIC2603DWR is recommended for designs requiring extended production lifecycles

Frequently Asked Questions (FAQ)

Q: Can TPIC2603DWRG4 be used as a direct replacement for TPIC2603DWR in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Tape & Reel versus Cut Tape & Digi-Reel®). PCB layout, schematic connections, and performance characteristics remain unchanged.

Q: What does "Discontinued at DiGi Electronics" mean for TPIC2603DWRG4?

A: This indicates the part is no longer actively stocked or distributed through DiGi Electronics. Existing inventory may be available through alternative channels, but future availability is not guaranteed. For new designs, TPIC2603DWR is the recommended choice.

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

A: No. Both parts share identical electrical specifications: 350mA maximum output current, 1.7Ohm typical on-resistance, 1:6 output configuration, and identical fault protection features.

Q: Do both parts support the same operating temperature range?

A: Yes. Both operate from -40°C to 125°C (TA), making them suitable for industrial and automotive applications within this range.

Q: What is the significance of the packaging format difference?

A: Tape & Reel (TR) format is standard for high-volume automated assembly. Cut Tape (CT) & Digi-Reel® format is used for lower-volume orders or specific assembly line requirements. The physical component dimensions and electrical performance are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both TPIC2603DWR and TPIC2603DWRG4 are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for most applications.

Q: Can I mix these parts in the same production batch?

A: Yes, provided your assembly process can accommodate both Tape & Reel and Cut Tape & Digi-Reel® formats. Electrically and mechanically, they are interchangeable.
