Procurement Notes

Verify current availability status as the manufacturer has announced discontinuation of this model due to lack of sales volume and diminishing demand. Confirm final unit status before committing to procurement plans, as active ordering may no longer be supported by the original equipment manufacturer.

Selection Notes

This component is specifically engineered for T1/E1 transformer functions within telecommunications infrastructure. Selection should focus on verifying compatibility with existing STM-1 circuit designs. Due to the discontinued status, alternative sourcing or redesign strategies may be necessary for new production runs.

Part Context

The PT75161EL belongs to Bourns' specialty transformers portfolio, categorized under audio and signal transformers. It serves as a critical passive component for maintaining signal integrity in digital telephony networks, specifically addressing the requirements for T1 and E1 standard data transmission interfaces.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Given the discontinuation notice, engineers must identify equivalent T1/E1 transformers from other manufacturers or evaluate newer Bourns series that meet identical electrical specifications.
