FFF CompatibilityStandard 14-pin DIP pinout matches the target SN74LS13N.DIP-14 through-hole package form factor matches the target.Designed specifically as a direct cross-reference replacement with equivalent logic and safety thresholds.Pin assignments are completely different because it contains four 2-input gates instead of two 4-input gates.Standard DIP-14 through-hole package matches the target's physical size.Implements a quad 2-input NAND configuration instead of the dual 4-input configuration.
AI Summary

SN74LS13N by Texas Instruments: Logic Gates Dual 4-input Positive-NAND Schmitt triggers 14-PDIP 0 to 70.

This is a widely available commercial replacement module designed to match the SN74LS13N in all mechanical and electrical dimensions, ideal for maintenance and legacy board designs.

  • Commonly available high-reliability replacement part
  • Identical electrical and mechanical specifications

This is an adjacent-function sibling in the same family and package. Although it physically mounts into the same DIP-14 socket, the pinout and gate configuration are different (quad 2-input instead of dual 4-input), making it function as a partial equivalent that requires circuit/wiring adjustments.

  • Widely active production line from the same manufacturer
  • Fits the same physical 14-pin DIP socket footprint
  • Provides four Schmitt-Trigger gates instead of only two
  • Different gate structure: quad 2-input gates instead of dual 4-input gates
  • Incompatible pin assignments require schematic adjustments

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.
