Equivalent & Substitute Parts Reference for TSRN 1-2418

Part Overview

The Traco Power TSRN 1-2418 is a DC DC Converter designed as a linear regulator replacement, providing 1 output of 1.8V at 1A with an input voltage range of 4.6V to 36V and a maximum power output of 1.8W. This module features OTP (Over Temperature Protection) and SCP (Short Circuit Protection), operates over a temperature range of -40°C to 85°C (with derating), and offers 80% efficiency. It is packaged in a 3-SIP module for through-hole mounting and is suitable for ITE (Commercial) applications. The TSRN 1-2418 is discontinued at Digi-Key, making the identification of substitute models necessary for continued design support, procurement, and maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitute part selection for the TSRN 1-2418 is strictly based on key electrical and mechanical parameters: type (Linear Regulator Replacement), number of outputs (1), output voltage (1.8V), output current (1A), maximum power (1.8W), input voltage range compatibility, efficiency, integrated protection features (OTP, SCP), operating temperature range, mounting type (Through Hole), and package/case (3-SIP Module). Additional selection criteria are RoHS compliance and matching commercial application classification. Only parts that match these explicit parameters are considered viable substitutes.

Parameter Comparison

Engineering Selection Recommendations

Substitutes must possess identical environmental compliance (ROHS3, REACH Unaffected, ECCN EAR99, HTSUS 8504.40.9580) and be available with similar packaging and mounting style (Through Hole, 3-SIP Module). The R-78C1.8-1.0 from Recom Power is designated as a substitute part. Product selection should be based on active status and equivalent compliance documentation. No additional criteria are introduced.
