TLC393IPG4 Equivalent & Substitute Parts

Part Overview

The TLC393IPG4 is a dual general-purpose comparator from Texas Instruments' LinCMOS™ series, featuring MOS open-drain outputs in an 8-DIP through-hole package. This device is designed for precision voltage comparison applications requiring low input offset voltage and low input bias current across a wide supply voltage range of 3V to 16V.

The TLC393IPG4 is currently discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing production and maintenance applications. Suitable alternatives maintain identical electrical performance while offering different packaging formats or current product status to ensure design continuity.

Substitute Part Grouping Explanation

Substitute parts for the TLC393IPG4 are qualified based on the following criteria:

Electrical Equivalence: All substitute parts 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 (65µA maximum), CMRR (84dB), propagation delay (4.5µs maximum), and operating temperature range (-40°C ~ 85°C).

Functional Equivalence: All parts contain the same number of elements (2 comparators) with identical output type (MOS, open-drain) and belong to the same LinCMOS™ series with base product number TLC393.

Compliance Equivalence: All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility.

Package Differences: Substitutes differ in physical packaging format (8-SOIC surface mount versus 8-DIP through-hole) and product status (active versus last-time-buy), allowing selection based on manufacturing process and supply chain requirements.

Parameter Comparison

Engineering Selection Recommendations

TLC393IDR (Primary Substitute): This part is the manufacturer-recommended substitute with active product status, ensuring long-term availability and supply chain stability. The 8-SOIC surface-mount package requires PCB redesign but is suitable for modern manufacturing processes. Select this part for new designs or production transitions where surface-mount assembly is available.

TLC393IP (Secondary Substitute): This part maintains the same 8-DIP through-hole package as the original TLC393IPG4, enabling direct board-level replacement without layout modifications. However, its last-time-buy status indicates limited future availability. Select this part for immediate replacement in existing through-hole designs where supply is still available.

Both substitutes maintain full electrical and regulatory compliance with the original part, ensuring functional equivalence in all application contexts.

Frequently Asked Questions (FAQ)

Q: Can TLC393IDR replace TLC393IPG4 directly on the PCB? A: No. TLC393IDR uses an 8-SOIC surface-mount package while TLC393IPG4 uses an 8-DIP through-hole package. PCB redesign is required, but electrical performance is identical.

Q: Can TLC393IP replace TLC393IPG4 directly on the PCB? A: Yes. TLC393IP uses the same 8-DIP through-hole package and pin configuration as TLC393IPG4, allowing direct board-level substitution without layout changes.

Q: Are all three parts electrically identical? A: Yes. TLC393IPG4, TLC393IDR, and TLC393IP share identical electrical specifications across all key parameters including supply voltage, input offset voltage, input bias current, output current, quiescent current, CMRR, propagation delay, and operating temperature range.

Q: What is the difference between these parts? A: The primary differences are packaging format (8-DIP through-hole versus 8-SOIC surface-mount) and product status (discontinued, active, or last-time-buy). Electrical performance and functional behavior are identical.

Q: Which substitute should I choose for a new design? A: TLC393IDR is recommended for new designs due to its active product status and long-term availability, despite requiring surface-mount assembly capability.

Q: Which substitute should I choose for immediate replacement? A: TLC393IP is suitable for immediate replacement in existing through-hole designs, as it requires no PCB modifications. However, verify availability due to its last-time-buy status.

Q: Are all parts RoHS and REACH compliant? A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.
