Alternative Part Number

  • TEA1062 --: Speech transmission IC from the same TEMIC/Telefunken lineage, now produced by NXP; functionally similar telephone speech circuit and widely available as a replacement.
  • MC34119 --: Low-power audio amplifier commonly used in telephone handset circuits; pin-compatible in many T4258N applications and readily sourced.
  • LM386 --: General-purpose low-voltage audio amplifier that can substitute in many speech/audio stages where the T4258N was used, with broad availability and low cost.
  • PBL3782 --: Telecom line interface/subscriber line circuit in the same function class as the T4258N, widely used as a drop-in replacement in telecom line card designs.
  • LE58QL021 --: Subscriber line interface circuit (SLIC) offering comparable telecom line interface functionality and a common cross-reference for TFK T4258N designs.
  • HC55185 --: SLIC device with similar line interface role and electrical characteristics, suitable as a functional substitute where pinout adaptation is acceptable.
