Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLC3702CPSR is determined by the following critical parameters:

Primary Substitution Criteria:

• Number of Elements: 2 (dual comparator configuration)
• Output Type: CMOS, Push-Pull, TTL compatibility
• Voltage - Supply Range: Minimum 3V to 16V overlap required
• Package Category: 8-pin surface mount (SOIC or equivalent footprint)
• Mounting Type: Surface Mount

Secondary Compatibility Factors:

• Input Offset Voltage: Maximum 5mV @ 10V
• Input Bias Current: Maximum 5pA @ 5V
• Output Current: Typical 20mA
• Quiescent Current: Maximum 50µA
• CMRR: Minimum 84dB
• Operating Temperature: 0°C ~ 70°C minimum range

Substitute parts are grouped based on their ability to meet or exceed these parameters within the specified operating conditions. Parts with narrower supply voltage ranges, different output types, or incompatible package footprints are excluded from direct substitution.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Highest Compatibility):

TLC3702CDR is the primary recommended substitute. Manufactured by Texas Instruments, this part maintains identical electrical specifications to the TLC3702CPSR while offering Active product status. The only difference is packaging format (Cut Tape & Digi-Reel® versus Tape & Reel) and a narrower SOIC body width (3.90mm versus 5.30mm). This part is suitable for designs where the smaller package footprint is compatible with PCB layout requirements.

TS3702IDT from STMicroelectronics provides equivalent functionality with extended operating temperature range (-40°C to 125°C versus 0°C to 70°C). This part maintains the same supply voltage range, output type, and key electrical parameters. The wider temperature range makes this suitable for industrial or automotive applications requiring enhanced thermal performance.

Conditional Substitutes (Application-Dependent):

MAX962ESA+ and MAX962EUA+T from Analog Devices Inc./Maxim Integrated are functionally equivalent but operate within a narrower supply voltage range (2.7V to 5.5V). These parts feature superior input offset voltage (1.5mV versus 5mV) and faster propagation delay (7ns versus 4.5µs). Selection of these parts requires confirmation that the 2.7V to 5.5V supply range meets application requirements. MAX962EUA+T uses a smaller 8-TSSOP/8-MSOP package (3.00mm width) compared to standard SOIC packages.

NCS3402DR2G from onsemi features Open-Drain output architecture, differing from the CMOS push-pull output of the TLC3702CPSR. This part is suitable only for applications designed to accommodate open-drain output topology. The extended operating temperature range (-40°C to 125°C) and superior PSRR (105dB) provide advantages in noise-sensitive applications.

TC75W57FU,LF from Toshiba Semiconductor and Storage operates across a wider supply voltage range (1.8V to 7V single supply, ±0.9V to ±4.6V dual supply) with faster propagation delay (140ns). This part is suitable for low-voltage applications and designs requiring enhanced speed performance.

Product Status Consideration:

All substitute parts maintain Active product status, ensuring long-term availability and continued manufacturing support. The TLC3702CPSR Last Time Buy status necessitates transition planning to one of these active alternatives.

Frequently Asked Questions (FAQ)

Q: Can TLC3702CDR directly replace TLC3702CPSR in existing designs?

A: Yes, TLC3702CDR is a direct electrical equivalent with identical specifications. The primary design consideration is package body width: TLC3702CDR uses a narrower 3.90mm SOIC package compared to the 5.30mm width of TLC3702CPSR. PCB layout compatibility must be verified before implementation.

Q: What is the key difference between TLC3702CDR and TS3702IDT?

A: Both parts are electrically equivalent with identical supply voltage range (3V to 16V) and output type (CMOS, Push-Pull). TS3702IDT extends the operating temperature range to -40°C to 125°C, making it suitable for industrial and automotive applications requiring enhanced thermal performance. TLC3702CDR maintains the original 0°C to 70°C range.

Q: Why do MAX962ESA+ and MAX962EUA+T have a narrower supply voltage range?

A: The MAX962 series is optimized for lower voltage applications (2.7V to 5.5V) and features superior input offset voltage and propagation delay characteristics. These parts are suitable only for designs operating within this voltage range. Applications requiring the full 3V to 16V range of the TLC3702CPSR must use TLC3702CDR, TS3702IDT, or NCS3402DR2G.

Q: Is NCS3402DR2G compatible with designs expecting push-pull output?

A: NCS3402DR2G features open-drain output architecture, which differs fundamentally from the CMOS push-pull output of TLC3702CPSR. This part requires external pull-up resistors and is suitable only for applications specifically designed for open-drain topology. Direct substitution in push-pull designs is not recommended without circuit redesign.

Q: What packaging options are available for substitute parts?

A: TLC3702CDR, MAX962ESA+, NCS3402DR2G, and TS3702IDT use standard 8-SOIC packages with 3.90mm body width. MAX962EUA+T uses a smaller 8-TSSOP/8-MSOP package (3.00mm width). TC75W57FU,LF uses an 8-TSSOP/8-MSOP package (2.80mm width). PCB footprint compatibility must be verified for each substitute selection.

Q: Which substitute part offers the best performance for noise-sensitive applications?

A: NCS3402DR2G provides the highest PSRR specification (105dB) and extended operating temperature range (-40°C to 125°C). However, the open-drain output architecture requires circuit redesign. For push-pull output applications, TS3702IDT offers competitive CMRR (82dB) with extended temperature range.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all substitute parts listed maintain ROHS3 compliance, ensuring compatibility with environmental and regulatory requirements equivalent to the TLC3702CPSR.
