Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC393IDRG4 is determined by strict equivalence across the following critical parameters:

• Dual comparator architecture (Number of Elements: 2)
• General-purpose comparator type with MOS open-drain output configuration
• Identical supply voltage range (3V ~ 16V)
• Matching electrical specifications: input offset voltage, input bias current, output current, quiescent current, CMRR, and propagation delay
• Identical 8-SOIC surface mount package footprint (0.154", 3.90mm Width)
• Operating temperature range (-40°C ~ 85°C)
• LinCMOS™ series classification
• Compliance with ROHS3, REACH, and MSL requirements

The TLC393IDR qualifies as a parametric equivalent substitute based on complete alignment with all specified electrical and mechanical parameters. The primary distinction is product status and packaging format availability.

• Equivalent regulatory compliance: ROHS3 Compliant, REACH Unaffected, MSL 1 (Unlimited)
• Same manufacturer (Texas Instruments) and LinCMOS™ series classification, ensuring consistent device behavior and long-term support

The TLC393IDR is available in Cut Tape (CT) and Digi-Reel® packaging formats, providing flexibility for both prototype and production volume requirements.

Frequently Asked Questions (FAQ)

Q: Can the TLC393IDR be used as a direct replacement for the TLC393IDRG4 in existing designs?

A: Yes. The TLC393IDR is a parametric equivalent with identical electrical specifications, package footprint, and mounting type. No circuit modifications or PCB redesign are required for substitution.

Q: What is the difference between TLC393IDRG4 and TLC393IDR?

A: The primary differences are product status and packaging format. The TLC393IDRG4 is obsolete, while the TLC393IDR is an active product. Both devices share identical electrical and mechanical specifications. The TLC393IDR is available in Cut Tape (CT) and Digi-Reel® packaging.

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

A: No. Both parts carry identical compliance certifications: ROHS3 Compliant, REACH Unaffected, and MSL 1 (Unlimited). They meet the same regulatory and environmental standards.

Q: What is the 8-SOIC package specification?

A: The 8-SOIC package is a surface mount small-outline integrated circuit with 8 pins, measuring 0.154 inches (3.90mm) in width. This package is standard for dual comparator ICs and ensures compatibility between the TLC393IDRG4 and TLC393IDR on existing PCBs.

Q: Is the TLC393IDR suitable for high-volume production?

A: Yes. The TLC393IDR is an active product with substantial inventory availability (17,101 units in stock) and is available in production-grade packaging formats (Cut Tape and Digi-Reel®), making it suitable for both prototype and high-volume manufacturing applications.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution compatibility is determined by matching 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).
