TSRN 1-2418A Equivalent & Substitute DC DC Converter Parts
Part Overview
The Traco Power TSRN 1-2418A is a DC DC converter designed as a linear regulator replacement. It provides a single 1.8V output at up to 1A with high efficiency, over-temperature protection (OTP), and short-circuit protection (SCP). The part accommodates a wide input range from 4.6V to 36V, uses a 3-SIP Module through-hole package, and is RoHS3 compliant. This model is currently discontinued at Digi-Key. Identifying alternative compatible models is crucial in applications requiring maintenance, redesign, or continued production.
