Substitute Part Grouping Explanation

Substitution eligibility for the TPIC46L01DB is determined by strict equivalence across the following critical parameters:

• Driven Configuration: Low-Side
• Number of Drivers: 6 independent channels
• Gate Type: N-Channel MOSFET
• Input Type: Non-Inverting logic
• Voltage - Supply: 4.5V ~ 5.5V
• Current - Peak Output: 1.2mA source, 1.2mA sink
• Rise / Fall Time: 4.6µs rise, 3µs fall (typical)
• Operating Temperature Range: -40°C ~ 150°C (TJ)
• Package / Case: 28-SSOP form factor
• Mounting Type: Surface Mount
• Compliance: ROHS3 and REACH standards

The TPIC46L01DBR qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. The primary distinction is packaging format: TPIC46L01DB is supplied in Tube packaging, while TPIC46L01DBR is supplied in Tape & Reel (TR) format. Both share the same base product number (TPIC46L01) and maintain full functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The TPIC46L01DBR is the manufacturer-recommended substitute for the TPIC46L01DB. Both parts maintain identical electrical and thermal specifications, ensuring functional interchangeability in circuit designs.

The TPIC46L01DB is designated Last Time Buy, indicating limited availability and imminent discontinuation. The TPIC46L01DBR carries Active product status with higher inventory availability (2325 pcs vs. 1388 pcs), providing superior supply chain continuity for new designs and ongoing production requirements.

Both parts satisfy ROHS3 compliance and REACH regulatory requirements. Selection between these parts should be based on packaging requirements: Tube format for lower-volume applications or Tape & Reel format for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Are TPIC46L01DB and TPIC46L01DBR electrically identical?

A: Yes. Both parts share identical electrical specifications including supply voltage (4.5V ~ 5.5V), peak output current (1.2mA source/sink), rise/fall times (4.6µs/3µs), and operating temperature range (-40°C ~ 150°C). They are functionally equivalent.

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

A: The primary difference is packaging format. TPIC46L01DB is supplied in Tube packaging, while TPIC46L01DBR is supplied in Tape & Reel (TR) format. Both use the same 28-SSOP surface mount package with identical PCB footprints.

Q: Why is TPIC46L01DB marked as Last Time Buy?

A: Last Time Buy designation indicates the manufacturer is discontinuing this part number. TPIC46L01DBR remains in Active production status, making it the recommended choice for new designs and long-term supply assurance.

Q: Can I use TPIC46L01DBR as a direct replacement in existing designs?

A: Yes. The TPIC46L01DBR is a direct substitute with identical electrical performance and mechanical compatibility. The 28-SSOP footprint and pin configuration are unchanged, requiring no circuit modifications.

Q: Which packaging format should I select?

A: Select Tube packaging (TPIC46L01DB) for manual assembly or low-volume production. Select Tape & Reel format (TPIC46L01DBR) for automated pick-and-place assembly processes and higher-volume manufacturing.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both TPIC46L01DB and TPIC46L01DBR are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for industrial and commercial applications.
