SFT14G Equivalent & Substitute Parts Reference

Part Overview

The SFT14G is a general-purpose rectifier diode from Taiwan Semiconductor Corporation, categorized under Diodes, Rectifiers. It features a maximum reverse voltage of 200 V, an average rectified current of 1A, and is housed in a T-18 Axial (TS-1) through-hole package. As an active product, it is available in inventory and compliant with relevant RoHS and REACH standards. Identifying equivalent or substitute models is necessary in order to support alternative sourcing strategies, supply chain flexibility, design qualification in automotive or industrial applications, and cross-referencing for repair or manufacturing requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SFT14G diode is determined strictly by matching the core electrical and mechanical parameters, ensuring full compatibility within the Diodes, Rectifiers category. Allowed substitutes must have identical or directly equivalent values for the following key parameters: maximum reverse voltage, average rectified current, forward voltage at the specified current, reverse recovery time, reverse leakage current, capacitance under test conditions, package type (T-18, Axial; TS-1), mounting type (Through Hole), operating temperature range, speed category, and compliance designations (RoHS, REACH, MSL, ECCN, HTSUS).

Parameter Comparison

Engineering Selection Recommendations

The SFT14G and its direct substitute SFT14GH share an identical set of provided electrical, mechanical, and compliance parameters. Both models are active and maintain ROHS3 compliance, REACH unaffected status, and a 1 (unlimited) moisture sensitivity rating. The SFT14GH additionally features automotive grade and AEC-Q101 qualification as specified. As both parts match all required product and regulatory standards outlined, selection may be determined by inventory availability and compliance preference without consideration for additional technical differences.

Frequently Asked Questions (FAQ)

Q1: Which parameters are required to match when selecting a substitute for the SFT14G diode?
