Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLC393IDG4 are qualified based on electrical and mechanical parameter equivalence within the TLC393 product family. The substitution criteria are strictly defined by the following parameters:

• Identical output type: MOS, Open-Drain
• Matching supply voltage range: 3V ~ 16V
• Equivalent input offset voltage: 5mV @ 10V
• Identical input bias current: 5pA @ 5V
• Matching output current capability: 20mA typical
• Identical quiescent current specification: 65µA maximum
• Equivalent propagation delay: 4.5µs maximum
• Identical operating temperature range: -40°C ~ 85°C
• Compatible package: 8-SOIC surface-mount form factor

All substitute parts maintain the same functional performance and electrical characteristics as the TLC393IDG4, differing only in packaging format (Tube versus Cut Tape & Digi-Reel®) and product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

The TLC393IDR is the primary substitute for the TLC393IDG4, offering identical electrical performance with Active product status and higher inventory availability (17,101 units). This part is supplied in Cut Tape and Digi-Reel® packaging formats, suitable for automated assembly processes. Selection of TLC393IDR eliminates supply chain risk associated with Last Time Buy status while maintaining full functional equivalence.

The TLC393ID provides an alternative substitute with Tube packaging identical to the TLC393IDG4. This part maintains Last Time Buy status but offers greater inventory depth (3,542 units) compared to the original TLC393IDG4 (1,157 units). The TLC393ID is appropriate for applications where Tube packaging is required or preferred for manual assembly workflows.

Both substitute parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment with the original TLC393IDG4 specification.

Frequently Asked Questions (FAQ)

Q: Are TLC393IDR and TLC393ID electrically identical to TLC393IDG4?

A: Yes. All three parts share identical electrical specifications including supply voltage range (3V ~ 16V), input offset voltage (5mV @ 10V), output current (20mA typical), propagation delay (4.5µs maximum), and operating temperature range (-40°C ~ 85°C). Functional performance is equivalent across all three part numbers.

Q: What is the difference between TLC393IDG4, TLC393IDR, and TLC393ID?

A: The primary differences are packaging format and product lifecycle status. TLC393IDG4 and TLC393ID are supplied in Tube packaging and both carry Last Time Buy status. TLC393IDR is supplied in Cut Tape and Digi-Reel® packaging with Active product status. All three parts use the 8-SOIC surface-mount package with identical pinout and mechanical dimensions.

Q: Can I substitute TLC393IDR for TLC393IDG4 in my design?

A: Yes. TLC393IDR is a direct electrical and mechanical substitute. The Cut Tape and Digi-Reel® packaging is compatible with standard automated pick-and-place assembly equipment. No circuit modifications or PCB layout changes are required.

Q: Which substitute should I select for new designs?

A: TLC393IDR is recommended for new designs due to Active product status, ensuring long-term availability and supply chain stability. This part eliminates obsolescence risk associated with Last Time Buy designations.

Q: Are there any compliance or certification differences between these parts?

A: No. All three parts maintain identical ROHS3 compliance, REACH Unaffected status, and Moisture Sensitivity Level 1 (Unlimited) ratings. Regulatory and environmental certifications are equivalent across all substitute options.

Q: What is the pinout compatibility between these parts?

A: All three parts use the 8-SOIC package with identical pinout configuration. Direct pin-for-pin substitution is supported without circuit modifications.
