TLC339MDR Equivalent & Substitute Parts

Part Overview

The TLC339MDR is a general-purpose CMOS comparator manufactured by Texas Instruments, housed in a 14-SOIC surface-mount package. This linear integrated circuit provides four independent comparator elements with open-drain output configuration, designed for applications requiring precision voltage comparison across industrial and commercial temperature ranges. The part maintains active product status with full RoHS3 compliance and unlimited moisture sensitivity rating, ensuring suitability for modern manufacturing environments. Substitute parts are identified to address packaging preferences, supply chain availability, or specific application requirements while maintaining functional equivalence within defined electrical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLC339MDR are qualified based on the following electrical and mechanical compatibility criteria:

Primary Substitution Parameters:

• Number of comparator elements: 4
• Mounting type: Surface Mount
• Package family: 14-SOIC or 16-SOIC (0.154" width)
• Output configuration: CMOS with open-drain or TTL capability
• Supply voltage range: Overlapping or encompassing 4V ~ 16V
• Product status: Active
• RoHS3 compliance: Required
• MSL rating: 1 (Unlimited)

Substitute Parts Identified:

1. CMP401GSZ (Analog Devices Inc.) - Tube packaging
2. CMP401GSZ-REEL (Analog Devices Inc.) - Cut Tape & Digi-Reel packaging
3. TS374CDT (STMicroelectronics) - Tape & Reel packaging
4. TS374IDT (STMicroelectronics) - Cut Tape & Digi-Reel packaging

All substitute parts maintain four-element comparator architecture, surface-mount configuration, and RoHS3 compliance. Packaging format variations (Tube, Cut Tape, Digi-Reel, Tape & Reel) accommodate different procurement and assembly workflows without affecting electrical function.

Parameter Comparison

Engineering Selection Recommendations

CMP401GSZ and CMP401GSZ-REEL (Analog Devices Inc.): These parts provide four-element comparator functionality with CMOS and TTL output capability. The 16-SOIC package requires PCB layout adjustment compared to the 14-SOIC TLC339MDR. Supply voltage specification of ±5V is narrower than the TLC339MDR range but suitable for applications operating within this window. Lower input offset voltage (3mV) and reduced input bias current (3µA) offer improved precision characteristics. Both variants maintain identical electrical specifications; selection between Tube and Cut Tape & Digi-Reel packaging depends on procurement and assembly requirements. All RoHS3 compliance and MSL ratings align with the main part.

TS374IDT (STMicroelectronics): This part offers four-element differential comparator architecture with extended supply voltage range (3V ~ 16V, ±1.5V ~ 8V) encompassing the TLC339MDR specification. The 14-SOIC package matches the main part footprint, eliminating PCB redesign requirements. Operating temperature range of -40°C ~ 125°C covers the primary industrial specification, with extended lower-temperature capability compared to the TS374CDT variant. Input bias current of 1pA represents superior performance relative to the TLC339MDR. Cut Tape & Digi-Reel packaging accommodates standard assembly workflows. Full RoHS3 compliance and MSL rating 1 maintained.

TS374CDT (STMicroelectronics): This variant shares identical electrical specifications with TS374IDT but operates within a restricted temperature range of 0°C ~ 70°C, limiting applicability to commercial-grade applications. Tape & Reel packaging format provides alternative procurement options. Selection of this part requires confirmation that application operating temperatures remain within the specified 0°C ~ 70°C window.

All substitute parts maintain active product status, RoHS3 compliance, and unlimited moisture sensitivity rating, ensuring compatibility with current manufacturing and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can CMP401GSZ be used as a direct replacement for TLC339MDR without PCB modification?

A: The CMP401GSZ uses a 16-SOIC package compared to the TLC339MDR 14-SOIC package. Both packages maintain 0.154" width and surface-mount configuration, but the 16-pin layout differs from the 14-pin layout. PCB footprint modification is required. The CMP401GSZ-REEL variant provides identical electrical specifications with alternative packaging format.

Q: What is the primary difference between TS374CDT and TS374IDT?

A: Both parts share identical electrical specifications and 14-SOIC package configuration. The primary distinction is operating temperature range: TS374CDT operates 0°C ~ 70°C (commercial grade), while TS374IDT operates -40°C ~ 125°C (industrial grade). Selection depends on application temperature requirements.

Q: Does the TLC339MDR supply voltage range of 4V ~ 16V encompass the CMP401GSZ specification of ±5V?

A: The CMP401GSZ ±5V specification represents a dual-supply configuration (±5V = +5V and -5V rails). The TLC339MDR 4V ~ 16V represents single-supply operation. These are distinct supply topologies. Application compatibility requires verification that the circuit design accommodates the selected supply configuration.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. CMP401GSZ, CMP401GSZ-REEL, TS374CDT, and TS374IDT all maintain ROHS3 Compliant status with MSL rating 1 (Unlimited), matching the TLC339MDR compliance profile.

Q: What packaging options are available for each substitute part?

A: CMP401GSZ is supplied in Tube packaging. CMP401GSZ-REEL is supplied in Cut Tape & Digi-Reel format. TS374CDT is supplied in Tape & Reel format. TS374IDT is supplied in Cut Tape & Digi-Reel format. Packaging selection accommodates different procurement workflows and assembly processes.

Q: Can TS374CDT be used in applications requiring -55°C operation?

A: No. TS374CDT operates within 0°C ~ 70°C range and does not support the -55°C lower temperature limit of the TLC339MDR. TS374IDT supports -40°C ~ 125°C and is suitable for extended industrial temperature applications.
