TLC393IPWG4 Equivalent & Substitute Parts

Part Overview

The TLC393IPWG4 is a dual general-purpose comparator IC manufactured by Texas Instruments, part of the LinCMOS™ series. This device features MOS open-drain output architecture and operates across a 3V to 16V supply voltage range. The TLC393IPWG4 is classified as obsolete, making identification of equivalent and substitute parts essential for design continuity and procurement planning. Substitute parts maintain identical electrical performance and mechanical compatibility while offering improved availability or active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLC393IPWG4 are qualified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Electrical Parameters (Must Match):

• Dual comparator configuration (2 elements)
• MOS open-drain output architecture
• Supply voltage range: 3V ~ 16V
• Input offset voltage: 5mV @ 10V maximum
• Input bias current: 5pA @ 5V maximum
• Output current: 20mA typical
• CMRR: 84dB typical
• Propagation delay: 4.5µs maximum
• Operating temperature: -40°C ~ 85°C

Mechanical Parameters (Must Match):

• Package type: 8-TSSOP
• Package dimensions: 0.173" × 4.40mm width
• Surface mount configuration
• Base product number: TLC393

Compliance Parameters:

• RoHS3 compliance required
• MSL rating: 1 (Unlimited)

Substitute parts may differ in packaging format (tube vs. tape & reel) and product status (active vs. obsolete), provided all electrical and mechanical specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

TLC393IPW: This substitute maintains identical electrical specifications and 8-TSSOP package configuration as the TLC393IPWG4. Both devices carry obsolete product status. Selection of TLC393IPW is appropriate for applications requiring tube packaging format and where inventory of the original part number is unavailable. Compliance certifications (ROHS3, MSL 1) are equivalent.

TLC393IPWR: This substitute is the preferred alternative for new designs and ongoing production. The TLC393IPWR maintains all critical electrical parameters and mechanical compatibility while offering active product status from Texas Instruments. The tape & reel packaging format supports automated assembly processes. Quiescent current is specified at 40µA maximum, compared to 65µA for the TLC393IPWG4, representing improved power efficiency. All compliance requirements (ROHS3, MSL 1) are satisfied. Higher inventory availability (16,040 pcs) supports supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can TLC393IPW and TLC393IPWR be used interchangeably with TLC393IPWG4?

A: Yes. Both substitute parts meet all electrical and mechanical specifications required for direct replacement. The primary differences are packaging format (tube vs. tape & reel) and product status (obsolete vs. active). Electrical performance and pinout are identical.

Q: What is the difference between tube and tape & reel packaging?

A: Tube packaging (TLC393IPW) is suitable for manual assembly and lower-volume applications. Tape & reel packaging (TLC393IPWR) is designed for automated pick-and-place assembly processes and higher-volume production. Both formats contain identical die and electrical specifications.

Q: Why is TLC393IPWR recommended over TLC393IPW?

A: TLC393IPWR carries active product status from Texas Instruments, ensuring long-term availability and manufacturing support. The tape & reel format supports modern assembly workflows. Quiescent current specification of 40µA maximum provides improved power efficiency compared to the 65µA maximum of earlier variants. Inventory availability is significantly higher.

Q: Are there any thermal or performance differences between these parts?

A: No. All three part numbers operate within identical temperature ranges (-40°C ~ 85°C) and deliver equivalent performance metrics. Propagation delay, CMRR, and output drive capability are specified identically.

Q: What compliance certifications apply to substitute parts?

A: All substitute parts maintain ROHS3 compliance and MSL rating 1 (Unlimited moisture sensitivity level). No additional handling or storage precautions are required beyond standard ESD protection.

Q: Can I mix packaging formats in the same production run?

A: Yes. Tube and tape & reel formats contain identical components and can be used interchangeably from an electrical and functional perspective. Assembly process compatibility should be evaluated based on production equipment capabilities.
