TLC339CPWR Equivalent & Substitute Parts

Part Overview

The TLC339CPWR is a general-purpose CMOS comparator IC manufactured by Texas Instruments, housed in a 14-TSSOP surface-mount package. This device features four independent comparator elements with open-drain outputs, designed for applications requiring precision voltage comparison across a wide supply voltage range of 3V to 16V. The part maintains active product status with full RoHS3 compliance and unlimited moisture sensitivity rating, making it suitable for industrial and commercial applications. Substitute parts are identified when equivalent functional performance can be achieved within the specified electrical and mechanical parameters of this product category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLC339CPWR is determined by the following critical parameters:

Primary Substitution Criteria:

• Number of comparator elements: 4
• Output type: CMOS, Open-Drain
• Supply voltage compatibility: Minimum 3V operation required
• Package compatibility: Surface-mount only
• Product status: Active
• RoHS3 compliance: Required

Substitution Logic: Parts are grouped as direct substitutes when they maintain identical comparator element count, open-drain output architecture, and surface-mount configuration. Supply voltage ranges may extend beyond the original specification without compromising substitution validity. Package form factors (14-TSSOP versus 14-SOIC) represent mechanical alternatives suitable for equivalent circuit implementations. Temperature operating ranges may differ based on manufacturer specifications without affecting functional substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and full RoHS3 compliance, meeting baseline compliance requirements for the TLC339CPWR application space.

TS339IPT (STMicroelectronics): Provides direct package compatibility in 14-TSSOP form factor with identical open-drain output architecture. Maintains matching input offset voltage specification of 5mV and output current rating of 20mA. Extended operating temperature range to -40°C ~ 125°C accommodates broader environmental conditions. Identical supply voltage range compatibility (2.7V ~ 16V) supports existing circuit designs without modification.

TS339CDT (STMicroelectronics): Offers functional equivalence with 14-SOIC package alternative. Maintains open-drain output type and four-element configuration. Superior input bias current specification of 1pA versus 5pA provides enhanced performance margin. Extended temperature range supports industrial applications. Package transition requires PCB layout adjustment.

CMP401GSZ-REEL and CMP402GSZ-REEL (Analog Devices Inc.): Provide four-element comparator functionality with 16-SOIC packaging. Output type transitions to CMOS/TTL configuration, requiring circuit interface verification. Supply voltage specification limited to ±5V represents narrower operating range compared to TLC339CPWR. Propagation delay specifications differ significantly (30ns and 75ns respectively versus 4.5µs), affecting timing-critical applications.

Frequently Asked Questions (FAQ)

Q: Can TS339IPT directly replace TLC339CPWR without PCB modification? A: Yes. TS339IPT matches the 14-TSSOP package footprint, pin configuration, and open-drain output architecture. Electrical specifications remain compatible within the specified supply voltage range of 2.7V ~ 16V.

Q: What is the primary difference between TS339CDT and TS339IPT? A: Both are STMicroelectronics TS339 base products with identical electrical specifications. TS339CDT uses 14-SOIC packaging (Tape & Reel), while TS339IPT uses 14-TSSOP packaging (Cut Tape & Digi-Reel). Package selection depends on PCB layout requirements and assembly process compatibility.

Q: Why do CMP401GSZ-REEL and CMP402GSZ-REEL have different output types? A: Both Analog Devices parts feature CMOS/TTL output configuration rather than open-drain. This output type difference requires circuit interface verification, particularly in applications relying on open-drain pull-up characteristics.

Q: Are the Analog Devices CMP401 and CMP402 series interchangeable? A: Both maintain four-element comparator architecture and 16-SOIC packaging. Primary difference is propagation delay specification: CMP401GSZ-REEL specifies 30ns maximum while CMP402GSZ-REEL specifies 75ns maximum. Selection depends on timing requirements of the target application.

Q: What supply voltage range applies to all substitute parts? A: TLC339CPWR operates at 3V ~ 16V. STMicroelectronics TS339 variants support 2.7V ~ 16V or ±1.35V ~ 8V configurations. Analog Devices CMP401/CMP402 series operate at ±5V. Verify supply voltage compatibility with circuit design before substitution.

Q: Do all substitute parts maintain RoHS3 compliance? A: Yes. All listed substitute parts carry ROHS3 Compliant status with unlimited moisture sensitivity rating (MSL 1), matching the compliance profile of TLC339CPWR.
