FFF CompatibilityPin assignments and count are identical in the standard 16-pin SOIC package.Both devices use the standard 16-pin SOIC package with identical physical dimensions.Core electrical parameters, dual error amplifiers, 5V reference, and output drive capability match perfectly.Pinouts match exactly with the TL494.Standard 16-pin SOIC footprint remains unchanged.Exceeds the performance of the TL494 by offering a more accurate reference regulator.
AI Summary

TL494 by onsemi: onsemi ANA SMPS DB END HI FREQ.

This is a direct pin-to-pin drop-in alternative from Texas Instruments with identical electrical characteristics and physical footprint. It serves as an ideal second-source option.

  • Direct drop-in second-source replacement from a top-tier manufacturer
  • Identical SOIC-16 package and footprint
  • Exact pinout match with no PCB modification required

The TL594 is an enhanced, pin-compatible version of the TL494 that features a much tighter internal reference voltage tolerance (1% vs. 5%) for designs requiring higher precision.

  • Upgraded internal voltage reference precision of 1% (versus 5% on the TL494)
  • Drop-in pinout compatibility in the same SOIC-16 package
  • Identical switching control topologies supported

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
