Key Parameters

Substitute Part Grouping Explanation

Substitution for the TPIC6259DWR is based on the following critical parameters:

• Logic Type & Circuit Configuration: D-Type, Addressable 1:8 functionality
• Supply Voltage Compatibility: Operating range of 4.5V to 5.5V
• Operating Temperature Range: -40°C to 125°C
• Output Type: Standard output characteristics
• Compliance & Certifications: RoHS3 compliance and REACH unaffected status
• Propagation Delay: 625ns timing specification

The identified substitute part, TLC6C5816QPWPRQ1, operates within overlapping voltage parameters (3V to 5.5V supply range) and maintains the same operating temperature range. However, this substitute represents a functional alternative rather than a pin-for-pin replacement, as it operates in a different product category (Power Management / LED Driver) with different circuit topology (Shift Register with PWM dimming capability).

Parameter Comparison

Engineering Selection Recommendations

The TPIC6259DWR is currently in Last Time Buy status, necessitating alternative component identification for new designs or long-term supply assurance. The TLC6C5816QPWPRQ1 is an active product from the same manufacturer, ensuring ongoing availability and support.

Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial applications. The TLC6C5816QPWPRQ1 carries AEC-Q100 automotive qualification, providing additional reliability assurance for demanding environments.

The upper supply voltage limit of 5.5V is common to both devices, ensuring compatibility within standard logic voltage domains. The TLC6C5816QPWPRQ1 extends the lower supply voltage limit to 3V, offering greater flexibility in low-voltage applications.

Selection between these components should be based on specific circuit topology requirements, output channel count needs, and application-specific performance criteria such as propagation delay and output current specifications.

Frequently Asked Questions (FAQ)

Q: Can the TLC6C5816QPWPRQ1 directly replace the TPIC6259DWR in existing designs?

A: Direct replacement is not possible due to differences in package type (20-SOIC versus 28-PowerTSSOP), pin configuration, and functional topology. The TLC6C5816QPWPRQ1 operates as a shift register with PWM dimming capability, whereas the TPIC6259DWR functions as an addressable latch. Circuit redesign is required for substitution.

Q: What are the key voltage compatibility considerations?

A: Both components operate within a 4.5V to 5.5V overlap range. The TLC6C5816QPWPRQ1 supports lower supply voltages down to 3V, making it suitable for applications requiring extended voltage range operation. Designs operating strictly within 4.5V to 5.5V will function with either component.

Q: Are both components suitable for industrial temperature applications?

A: Yes. Both the TPIC6259DWR and TLC6C5816QPWPRQ1 maintain operating temperature specifications of -40°C to 125°C, meeting industrial temperature requirements. The TLC6C5816QPWPRQ1 additionally carries AEC-Q100 automotive qualification.

Q: What compliance certifications apply to both components?

A: Both components are ROHS3 compliant and REACH unaffected, satisfying environmental and regulatory requirements for commercial and industrial applications.

Q: How do package differences affect substitution decisions?

A: The TPIC6259DWR uses a 20-SOIC package (0.295", 7.50mm width), while the TLC6C5816QPWPRQ1 uses a 28-PowerTSSOP package (0.173", 4.40mm width). Package differences require PCB layout modifications and cannot be accommodated through simple component swapping.
