TLC3702CP Equivalent & Substitute Parts

Part Overview

The TLC3702CP is a dual general-purpose comparator IC manufactured by Texas Instruments, housed in an 8-DIP through-hole package. This LinCMOS™ series device features CMOS push-pull TTL output architecture and operates across a 3V to 16V supply range. The TLC3702CP holds Last Time Buy status, indicating end-of-life designation. Identifying equivalent and substitute parts is necessary for design continuity, inventory management, and transition to active production alternatives that maintain functional and electrical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLC3702CP is determined by the following critical parameters:

Functional Equivalence Criteria:

• Dual comparator architecture (2 elements)
• General-purpose comparator classification
• CMOS and TTL-compatible output stages
• Supply voltage range compatibility (minimum 3V ~ 16V overlap)
• Input offset voltage within acceptable tolerance (≤5mV @ 10V)
• Input bias current specification (≤5pA @ 5V)
• Output current capability (≥20mA typical)
• Quiescent current (≤50µA maximum)
• Common-mode rejection ratio (≥84dB)

Package and Mounting Considerations:

• Through-hole DIP packages are functionally equivalent to surface-mount alternatives (SOIC, SSOP, uMAX) when PCB layout accommodates the different form factor
• Pin-to-pin functional compatibility must be verified for each application

Compliance Requirements:

• RoHS3 compliance maintained across all substitutes
• REACH unaffected status consistent

The three substitute parts listed below meet these criteria with varying degrees of parameter overlap and package form factors.

Parameter Comparison

Engineering Selection Recommendations

TLC3702CDR (Texas Instruments, 8-SOIC)

The TLC3702CDR is the direct functional equivalent of the TLC3702CP, maintaining identical electrical specifications including 3V ~ 16V supply range, 5mV input offset, 84dB CMRR, and 4.5µs propagation delay. The primary difference is packaging: surface-mount 8-SOIC versus through-hole 8-DIP. This substitute is recommended for new designs or PCB revisions that accommodate surface-mount technology. Product status is Active, ensuring long-term availability. RoHS3 compliance and MSL 1 rating support manufacturing continuity.

MAX962EUA+T (Analog Devices Inc./Maxim Integrated, 8-uMAX/uSOP)

The MAX962EUA+T operates within a narrower supply voltage range (2.7V ~ 5.5V) compared to the TLC3702CP (3V ~ 16V), limiting its applicability to designs operating exclusively within this window. However, it offers superior performance characteristics: 1.5mV input offset (versus 5mV), 7ns propagation delay (versus 4.5µs), and extended operating temperature range (-40°C ~ 85°C). The uMAX package provides the smallest footprint among substitutes. This part is suitable for low-voltage, high-speed applications where the restricted supply range does not conflict with system requirements. Product status is Active.

TC75W56FK,LF (Toshiba Semiconductor and Storage, 8-SSOP)

The TC75W56FK,LF supports the widest supply voltage range (1.8V ~ 7V, ±0.9V ~ 4.6V) and exhibits the lowest input bias current (1pA @ 5V). Propagation delay is 680ns, intermediate between the TLC3702CP and MAX962EUA+T. Output current capability is 25mA, exceeding the TLC3702CP specification. This part accommodates ultra-low-voltage applications and designs requiring minimal input bias current. CMRR and PSRR specifications are not provided. Product status is Active. The 8-SSOP package is compact and suitable for space-constrained layouts.

All three substitutes maintain RoHS3 compliance and REACH unaffected status, supporting regulatory requirements equivalent to the original part.

Frequently Asked Questions (FAQ)

Q: Can the TLC3702CDR directly replace the TLC3702CP in existing through-hole PCB designs?

A: The TLC3702CDR is electrically equivalent but requires PCB layout modification. The 8-SOIC surface-mount package cannot be installed in through-hole DIP sockets. Adapter boards or PCB redesign is necessary for mechanical compatibility. Electrical functionality remains identical.

Q: What is the primary limitation of the MAX962EUA+T as a substitute?

A: The MAX962EUA+T operates within a 2.7V ~ 5.5V supply range, whereas the TLC3702CP supports 3V ~ 16V. Applications requiring supply voltages above 5.5V cannot use this substitute. Verify system supply voltage specifications before selection.

Q: Which substitute offers the fastest propagation delay?

A: The MAX962EUA+T provides 7ns maximum propagation delay, significantly faster than the TLC3702CP (4.5µs) and TC75W56FK,LF (680ns). This performance advantage is relevant for high-speed signal processing applications.

Q: Are all substitutes RoHS3 compliant?

A: Yes. The TLC3702CDR, MAX962EUA+T, and TC75W56FK,LF all carry RoHS3 compliance certification, matching the original TLC3702CP. REACH unaffected status is consistent across all parts.

Q: Which substitute has the lowest input bias current?

A: The TC75W56FK,LF exhibits 1pA input bias current @ 5V, the lowest among all listed parts. The TLC3702CP and TLC3702CDR both specify 5pA, while the MAX962EUA+T specifies 15µA.

Q: Can surface-mount substitutes be used in through-hole applications?

A: Surface-mount packages (SOIC, uMAX, SSOP) require surface-mount PCB pads and soldering techniques. Direct installation in through-hole DIP sockets is not possible. Adapter boards or PCB redesign is required.

Q: What is the inventory status of these substitutes?

A: TLC3702CDR: 18,113 pcs in stock. MAX962EUA+T: 2,600 pcs in stock. TC75W56FK,LF: 1,145 pcs in stock. Availability varies; verify current stock before procurement.

Q: Is the TLC3702CP still available for purchase?

A: The TLC3702CP holds Last Time Buy status, indicating end-of-life designation. Current inventory is 27,622 pcs. New designs should transition to active alternatives such as the TLC3702CDR.
