FMW2T148 Equivalent & Substitute Parts Reference

Part Overview

FMW2T148 by Rohm Semiconductor is categorized as a Bipolar Junction Transistor (BJT) Array with a general-purpose NPN configuration. The device supports up to 50V across the collector and is housed in a 5-pin package. Its product status is Obsolete, requiring engineers and production managers to identify equivalent or substitute parts for ongoing designs, repairs, and supply continuity. This necessity arises due to the product's end-of-life (EOL) status and the demand for ongoing RoHS and REACH compliance in modern assemblies.

Key Parameters

Substitute Part Grouping Explanation

Substitution for FMW2T148 is based on category (Transistors, Bipolar (BJT)), transistor type (NPN), voltage rating (50V collector-emitter breakdown), and compliance with RoHS and REACH requirements. Substitutes must match these key electrical and regulatory parameters. Only explicitly provided parameters are used in determining substitution, without inferring package compatibility or enhanced functionalities.

Parameter Comparison

Engineering Selection Recommendations

FMW2T148 is classified as Obsolete. UMX1NTN is listed as an Active product and meets ROHS3 Compliant and REACH Unaffected requirements. Selection among compliant, active substitutes ensures continued availability and environmental certification adherence. Only parameters explicitly provided are considered.

Frequently Asked Questions (FAQ)

Q: What are the most crucial criteria for substituting FMW2T148?
A: Key criteria include identical device category (Transistors, Bipolar (BJT)), matching transistor type (NPN or NPN array), equivalent maximum collector-emitter voltage rating (50V), and regulatory compliance (RoHS and REACH).

Q: Is UMX1NTN a suitable replacement in terms of electrical parameters?
A: UMX1NTN matches the 50V voltage rating requirement and is in the same product category, fulfilling the core substitution parameters.

Q: Are there any notable differences in device type between FMW2T148 and UMX1NTN?
A: FMW2T148 is specified as NPN, while UMX1NTN provides 2 NPN (Dual) configuration. Only this explicitly supplied information is considered for comparison.

Q: How important are RoHS and REACH statuses in selection?
A: RoHS3 Compliant and REACH Unaffected statuses are mandatory for regulatory requirements and maintaining eligibility for most electronics supply chains.

Q: Does package type or mechanical compatibility play a role in this substitution?
A: Only mounting type information explicitly provided is "-". No further package compatibility is included in the provided parameters for this assessment.
