TLC393ID Equivalent & Substitute Parts

Part Overview

The TLC393ID is a dual general-purpose comparator IC manufactured by Texas Instruments, housed in an 8-SOIC surface-mount package. This LinCMOS™ series device features MOS open-drain outputs and operates across a 3V to 16V supply voltage range. The TLC393ID is currently in Last Time Buy status, making identification of equivalent and substitute parts essential for ongoing design support and procurement planning.

Engineering Selection Recommendations

TLC393IDR (MFR Recommended Primary Substitute)

The TLC393IDR is the preferred substitute for the TLC393ID. Both devices share identical electrical specifications, including supply voltage range (3V ~ 16V), input offset voltage (5mV @ 10V), input bias current (5pA @ 5V), output current (20mA), quiescent current (65µA), and CMRR (84dB). The TLC393IDR maintains Active product status with significantly higher inventory availability (17,101 units) compared to the Last Time Buy TLC393ID (3,542 units). Both are ROHS3 compliant with MSL 1 rating. The primary difference is packaging format: TLC393IDR is supplied in Cut Tape (CT) & Digi-Reel® format, while TLC393ID is supplied in Tube format. Pin configuration and electrical performance are identical, enabling direct substitution in all applications.

TS393IDT (Cross-Manufacturer Substitute)

The TS393IDT, manufactured by STMicroelectronics, provides an alternative from a different manufacturer while maintaining the same 8-SOIC package and dual-element configuration. The TS393IDT meets or exceeds the TLC393ID specifications in several parameters: input bias current is superior at 1pA @ 5V (versus 5pA @ 5V), quiescent current is lower at 25µA (versus 65µA), and operating temperature range extends to 125°C (versus 85°C). Supply voltage compatibility is enhanced with 2.7V ~ 16V single/dual operation. The TS393IDT is Active status with high inventory (22,736 units). CMRR is specified at 71dB, which is lower than the TLC393ID's 84dB. All devices are ROHS3 compliant with MSL 1 rating. The TS393IDT is suitable for applications where lower quiescent current or extended temperature range is beneficial.

TLC393IDG4 (Parametric Equivalent)

The TLC393IDG4 is a parametric equivalent sharing the TLC393 base product number with identical electrical specifications to the TLC393ID. Both devices feature the same 3V ~ 16V supply range, 5mV input offset, 5pA input bias current, 20mA output current, 65µA quiescent current, and 84dB CMRR. The TLC393IDG4 is supplied in Tube packaging, matching the TLC393ID format. Both are Last Time Buy status devices. Pin configuration and electrical performance are fully compatible. The TLC393IDG4 is suitable for applications requiring identical specifications with Tube packaging preference.

Frequently Asked Questions (FAQ)

Q: Can I use TLC393IDR as a direct replacement for TLC393ID?

A: Yes. The TLC393IDR is electrically identical to the TLC393ID with matching pin configuration, supply voltage range (3V ~ 16V), input offset voltage (5mV @ 10V), input bias current (5pA @ 5V), output current (20mA), quiescent current (65µA), and CMRR (84dB). The only difference is packaging format: TLC393IDR uses Cut Tape (CT) & Digi-Reel® while TLC393ID uses Tube. Both are 8-SOIC surface-mount packages with identical dimensions (0.154", 3.90mm Width). Direct substitution is valid for all circuit applications.

Q: What are the advantages of using TS393IDT over TLC393ID?

A: The TS393IDT offers three specific advantages: lower input bias current (1pA @ 5V versus 5pA @ 5V), lower quiescent current (25µA versus 65µA), and extended operating temperature range (-40°C ~ 125°C versus -40°C ~ 85°C). These characteristics make the TS393IDT suitable for low-power applications and designs requiring operation at elevated temperatures. The TS393IDT maintains the same 8-SOIC package, dual-element configuration, and 20mA output current. CMRR is specified at 71dB compared to 84dB for the TLC393ID.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The TLC393ID, TLC393IDR, TS393IDT, and TLC393IDG4 are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). All devices are suitable for applications requiring environmental compliance certification.

Q: What is the difference between Tube and Cut Tape (CT) & Digi-Reel® packaging?

A: Tube packaging supplies components in plastic tubes, typically used for lower-volume orders or manual assembly processes. Cut Tape (CT) & Digi-Reel® packaging supplies components on continuous tape wound on reels, optimized for automated pick-and-place assembly equipment. Both packaging formats contain identical components with the same electrical specifications and pin configuration. Selection depends on assembly process requirements and order volume.

Q: Can I substitute TS393IDT for TLC393ID in all applications?

A: The TS393IDT is electrically compatible with the TLC393ID in the same 8-SOIC package with identical pin configuration, dual-element count, and 20mA output current. However, the TS393IDT has lower CMRR (71dB versus 84dB). Applications sensitive to common-mode rejection ratio performance should evaluate this specification difference. The TS393IDT's lower quiescent current (25µA versus 65µA) and extended temperature range (-40°C ~ 125°C) make it advantageous for power-sensitive or high-temperature designs.

Q: Why is TLC393ID in Last Time Buy status?

A: Last Time Buy status indicates the manufacturer is discontinuing the product. Texas Instruments continues to support the TLC393ID through its Last Time Buy period, but long-term availability is limited. The TLC393IDR (Active status) is the recommended transition path, offering identical specifications with ongoing manufacturer support and higher inventory availability.
