RM516L121A-E2 Equivalent & Substitute Parts Reference

Part Overview

The RM516L121A-E2 from Nisshinbo Micro Devices Inc. is a non-isolated Point-of-Load (PoL) DC-DC converter module. It features an adjustable output voltage from 0.3V to 1.2V with a maximum output current of 100mA, supporting an input voltage range of 1.8V to 5.5V. Designed for ITE (Commercial) applications, it offers features such as adjustable output and remote on/off control. This device is supplied in an 8-WFQFN (QFN2430-8) surface mount package and is rated for operation from -40°C to 85°C. The part is currently obsolete, making identification of alternative models critical for ongoing designs and inventory management.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are determined strictly by matching key electrical parameters and package compatibility for the PoL DC-DC converter module category. Specifically, allowed substitutes must meet the following criteria: non-isolated PoL architecture, equal or greater input voltage range, compatible adjustable output voltage range, equal or greater maximum output current, identical output channel count, matching mounting type and package outline, as well as support for the same control features and application category (ITE). Parameters such as operating temperature range, MSL rating, and physical dimensions must also align exactly.

Parameter Comparison

Engineering Selection Recommendations

The RM516L121A-E2 is classified as obsolete. The substitute part RM517L121D-E2 is currently active and shares all key electrical, mechanical, and compliance parameters relevant to substitution. Both parts satisfy the same application category, output voltage and input voltage ranges, temperature ratings, packaging, and control feature requirements. Selection between the given options should be based on product lifecycle status and inventory availability as no additional certifications or compliance differences exist in the provided data.
