Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC393CPWRG4 is determined by strict equivalence across the following critical parameters:

• Dual comparator architecture (2 elements)
• MOS open-drain output configuration
• Supply voltage range: 3V ~ 16V
• Input offset voltage: 5mV @ 10V maximum
• Input bias current: 5pA @ 5V maximum
• Output current capability: 20mA typical
• Quiescent current: 40µA maximum
• Common-mode rejection ratio: 84dB typical
• Propagation delay: 4.5µs maximum
• Operating temperature range: 0°C ~ 70°C
• Package type: 8-TSSOP surface mount
• Compliance certifications: ROHS3, REACH Unaffected

The TLC393CPWR represents a parametric equivalent substitute, maintaining identical electrical specifications and mechanical compatibility while differing only in packaging format (Tape & Reel versus individual packaging).

Parameter Comparison

Engineering Selection Recommendations

The TLC393CPWR is the direct substitute for the obsolete TLC393CPWRG4. Both parts are manufactured by Texas Instruments and maintain identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: TLC393CPWRG4 is obsolete, while TLC393CPWR is active and currently in production.

Both parts satisfy ROHS3 compliance requirements and carry REACH Unaffected status, ensuring regulatory alignment for current manufacturing standards. The TLC393CPWR is available in Tape & Reel packaging format, which is standard for high-volume production environments.

Selection of TLC393CPWR ensures long-term supply chain continuity and access to current manufacturing batches with full traceability and compliance documentation.

Frequently Asked Questions (FAQ)

Q: Are TLC393CPWRG4 and TLC393CPWR electrically interchangeable?

A: Yes. Both parts are manufactured by Texas Instruments and maintain identical electrical specifications, including supply voltage range (3V ~ 16V), input offset voltage (5mV @ 10V), input bias current (5pA @ 5V), output current (20mA typical), quiescent current (40µA maximum), CMRR (84dB typical), and propagation delay (4.5µs maximum).

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