2SC2389STPS Equivalent & Substitute Parts Reference

Part Overview

The 2SC2389STPS, manufactured by Rohm Semiconductor, is an NPN bipolar junction transistor (BJT) with a maximum collector-emitter voltage of 120 V, a collector current of 50 mA, a power dissipation rating of 300 mW, and transition frequency of 140 MHz. This device is supplied in a through-hole SC-72 package and is RoHS3 compliant. With the status marked as obsolete, it is necessary to identify alternative BJTs with equivalent or superior specifications to ensure ongoing production support, repair, or design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are selected based strictly on matching essential electrical and mechanical parameters for NPN BJT transistors. Key parameters for substitution include transistor type, maximum collector current, maximum collector-emitter voltage, maximum power dissipation, transition frequency, mounting type, and package compatibility. Parts are grouped together as equivalents if they fully meet or exceed the electrical and mechanical constraints specifically listed above.

Parameter Comparison

Engineering Selection Recommendations

The 2SC2389STPS is classified as obsolete; the KSC1845FTA is active. Both KSC1845FTA and 2SC2389STPS are RoHS3 compliant and REACH unaffected, with ECCN code EAR99 and HTSUS 8541.21.0075. Both devices feature through-hole mounting and meet Moisture Sensitivity Level requirements (“Unlimited” for 2SC2389STPS and “Not Applicable” for KSC1845FTA). These compliance and status attributes are critical for maintaining design certification and regulatory adherence.

Frequently Asked Questions (FAQ)

Q1: What criteria are used to select substitute parts for 2SC2389STPS?
A1: Equivalent parts are selected based on transistor type (NPN), collector current, collector-emitter voltage, power dissipation, transition frequency, mounting type, package compatibility, and RoHS status.

Q2: Is KSC1845FTA a mechanically compatible replacement for the 2SC2389STPS?
A2: KSC1845FTA uses a through-hole TO-92-3 package with formed leads, while the 2SC2389STPS uses an SC-72 formed leads package. Mechanical compatibility should be confirmed at the assembly level, as both are through-hole but employ different case outlines.

Q3: Are there differences in maximum ratings or performance between 2SC2389STPS and KSC1845FTA?
A3: Both parts support 50 mA collector current and 120 V breakdown voltage. KSC1845FTA offers higher DC current gain and lower collector cutoff current, with a higher power rating and lower Vce saturation.

Q4: What compliance standards do these transistors meet?
A4: Both transistors are RoHS3 compliant and REACH unaffected.

Q5: Does product status affect selection?
A5: Yes. The 2SC2389STPS is obsolete; KSC1845FTA is active, supporting ongoing availability and supply chain reliability.
