Procurement Notes
This component is officially marked as obsolete and no longer manufactured by Pulse Electronics. Procurement should focus on the parameter-equivalent replacement part number TX1314NL. Verify availability through authorized distributors, as stock levels may be limited or subject to change. Ensure the replacement matches the original electrical specifications and mechanical footprint requirements for your design.
Selection Notes
Select the TX1314NLT only if legacy compatibility is required for existing designs. For new developments, consider the active equivalent TX1314NL. Confirm that the 1.2mH inductance and 1:1/1.26 turns ratio meet the specific impedance matching needs of the T1/E1 circuit. Check for RoHS compliance status if environmental regulations apply to the final product assembly.
Part Context
The TX1314NLT belongs to the family of small surface mount transformers designed for digital telephony. It supports standard T1 and E1 signaling protocols. The component integrates primary and secondary windings into a compact SMD form factor, facilitating space-constrained PCB layouts in telecom infrastructure hardware.
Replacement Considerations
The confirmed parameter-equivalent substitute is TX1314NL. This replacement maintains identical electrical characteristics and mechanical dimensions. Verify pinout compatibility before integration.
