TLC393CPS Equivalent & Substitute Parts

Part Overview

The TLC393CPS is a dual general-purpose comparator from Texas Instruments' LinCMOS™ series, featuring MOS open-drain outputs in an 8-SO surface mount package. This device is classified as Last Time Buy, indicating discontinued production with limited availability. The TLC393CPS operates across a 3V to 16V supply range and is designed for applications requiring low input offset voltage and minimal quiescent current. Finding equivalent substitute parts is necessary due to the Last Time Buy status, which restricts future procurement and necessitates transition to active production alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC393CPS is based on electrical and mechanical parameter equivalence within the LinCMOS™ comparator family. The primary substitute, TLC393CDR, maintains identical electrical specifications across all critical parameters: dual general-purpose comparator topology, MOS open-drain output configuration, 3V to 16V supply voltage range, 5mV maximum input offset voltage, 5pA maximum input bias current, 20mA typical output current, 50µA maximum quiescent current, 84dB CMRR, and 4.5µs maximum propagation delay. Both devices operate across the 0°C to 70°C temperature range and comply with ROHS3, REACH, and MSL requirements.

The key differentiator between TLC393CPS and TLC393CDR is packaging format and product status. The TLC393CPS is supplied in Tube packaging with Last Time Buy status, while the TLC393CDR is supplied in Cut Tape (CT) & Digi-Reel® packaging with Active product status. Both utilize 8-SO/8-SOIC surface mount packages with minor dimensional variations (5.30mm width for TLC393CPS versus 3.90mm width for TLC393CDR), which do not affect electrical performance or functional compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The TLC393CDR is the direct functional equivalent for TLC393CPS replacement. Selection of TLC393CDR is supported by three primary factors: electrical parameter equivalence across all specified criteria, Active product status ensuring long-term availability and supply chain continuity, and ROHS3 and REACH compliance matching the original device. The TLC393CPS Last Time Buy status creates procurement risk; transitioning to TLC393CDR eliminates this constraint while maintaining identical electrical performance and thermal characteristics.

Packaging format differences (Tube versus Cut Tape & Digi-Reel®) and minor package width variations (5.30mm versus 3.90mm) do not affect circuit functionality or PCB layout compatibility for standard surface mount assembly processes. Both devices are pin-compatible and functionally interchangeable at the circuit level.

Frequently Asked Questions (FAQ)

Q: Are TLC393CPS and TLC393CDR electrically identical? A: Yes. Both devices share identical electrical specifications including supply voltage range (3V to 16V), input offset voltage (5mV maximum), input bias current (5pA maximum), output current (20mA typical), quiescent current (50µA maximum), CMRR (84dB), propagation delay (4.5µs maximum), and operating temperature range (0°C to 70°C).

Q: What is the primary difference between these parts? A: The primary difference is product status and packaging format. TLC393CPS is Last Time Buy in Tube packaging, while TLC393CDR is Active in Cut Tape & Digi-Reel® packaging. Both use 8-SOIC surface mount packages with minor dimensional variations that do not affect functionality.

Q: Can TLC393CDR be used as a direct replacement for TLC393CPS? A: Yes. TLC393CDR is a direct functional replacement. Pin configuration, electrical performance, and thermal characteristics are identical. Standard surface mount assembly processes accommodate both package variants.

Q: Are both parts RoHS and REACH compliant? A: Yes. Both TLC393CPS and TLC393CDR are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What is the moisture sensitivity level for these devices? A: Both devices have Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Why should I transition from TLC393CPS to TLC393CDR? A: The TLC393CPS Last Time Buy status restricts future procurement availability. TLC393CDR Active status ensures continued supply chain access and long-term component availability without any electrical or functional compromise.
