TLC3702IPG4 Equivalent & Substitute Parts

Part Overview

The TLC3702IPG4 is a dual general-purpose CMOS comparator from Texas Instruments' LinCMOS™ series, housed in an 8-pin DIP package with through-hole mounting. This device provides push-pull TTL-compatible outputs suitable for signal comparison applications across a 3V to 16V supply range. The TLC3702IPG4 is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives that maintain electrical and mechanical compatibility with existing designs.

Engineering Selection Recommendations

TLC3702IDR (8-SOIC, Surface Mount): This is the manufacturer-recommended substitute with active product status and highest inventory availability (37,200 pcs). Electrical specifications are identical to the TLC3702IPG4. Selection of this part requires PCB redesign to accommodate surface-mount SOIC packaging instead of through-hole DIP. This option is suitable for new designs or board revisions where surface-mount assembly is feasible.

TLC3702IP (8-DIP, Through Hole): This substitute maintains identical package type and through-hole mounting compatibility with the TLC3702IPG4, enabling direct board-level replacement without layout modification. Product status is Last Time Buy, indicating limited future availability. This option is suitable for immediate replacement in existing designs where through-hole mounting is required and inventory can be secured before discontinuation.

Frequently Asked Questions (FAQ)

Q: Can TLC3702IDR replace TLC3702IPG4 directly on the PCB?

A: No. TLC3702IDR uses 8-SOIC surface-mount packaging, while TLC3702IPG4 uses 8-DIP through-hole packaging. Direct PCB replacement is not possible without board redesign and assembly process changes.

Q: Are the electrical specifications identical across all TLC3702 variants?

A: Yes. All TLC3702 variants (IPG4, IDR, IP) share identical electrical specifications including supply voltage range, input offset voltage, bias current, output current, CMRR, propagation delay, and operating temperature range.

Q: What is the difference between TLC3702IP and TLC3702IPG4?

A: Both use 8-DIP through-hole packaging and are electrically identical. The primary difference is product status: TLC3702IPG4 is discontinued at DiGi Electronics, while TLC3702IP is Last Time Buy. TLC3702IP offers a path to continued through-hole supply before full discontinuation.

Q: Are all TLC3702 variants RoHS3 compliant?

A: Yes. TLC3702IPG4, TLC3702IDR, and TLC3702IP are all ROHS3 compliant with REACH unaffected status.

Q: What packaging options are available for the TLC3702 base product?

A: The TLC3702 is available in two packaging options: 8-DIP (0.300", 7.62mm) for through-hole mounting, and 8-SOIC (0.154", 3.90mm Width) for surface-mount applications.

Q: Which substitute has the best inventory availability?

A: TLC3702IDR has the highest inventory with 37,200 pcs in stock. TLC3702IP has 1,445 pcs available but is Last Time Buy status.
