Equivalent & Substitute Parts for RN1911FE,LF(CT) (Toshiba Semiconductor and Storage)

Part Overview

RN1911FE,LF(CT) is a Pre-Biased Bipolar Transistor (BJT), featuring 2 NPN pre-biased (dual) transistors in a compact surface mount package (SOT-563/SOT-666), manufactured by Toshiba Semiconductor and Storage. The device supports a collector current up to 100mA, collector-emitter voltage of 50V, and integrates a 10kOhm base resistor. The component is currently active, but engineers frequently require substitute models due to factors such as multi-vendor sourcing, supply chain strategy, end-of-life status (for other parts), or inventory limitations. Compatibility mandates strict parameter matching for electrical and mechanical equivalence.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for RN1911FE,LF(CT) are determined strictly by matching essential electrical and mechanical parameters, including: transistor configuration (2 NPN - Pre-Biased Dual), maximum collector current (100mA), maximum collector-emitter breakdown voltage (50V), integrated base resistor value (10kOhms), mounting type (surface mount), and compatible package outlines (SOT-563, SOT-666). Only parts that explicitly share these critical parameters are categorized as suitable substitutes.

Parameter Comparison

Engineering Selection Recommendations

RN1911FE,LF(CT) holds an "Active" product status, while PEMH4,115 is marked as "Not For New Designs." PEMH4,115 is classified as ROHS3 Compliant and holds an MSL rating of 1 (Unlimited), consistent with the RN1911FE,LF(CT). For applications requiring active and currently promoted production parts, RN1911FE,LF(CT) aligns with those requirements based on status. Environmental and moisture sensitivity level parameters provided in the input support use where RoHS and MSL 1 compliance are mandatory.
