GS1KFL-TP Equivalent & Substitute Parts Reference

Part Overview

The Micro Commercial Co GS1KFL-TP is a standard recovery diode with an 800 V maximum DC reverse voltage, 1A average rectified current, and surface mount DO-221AC (SMA-FL) package. The device is classified as obsolete, requiring identification of compatible, in-stock alternatives for continued design support or maintenance where direct form, fit, and function replacements are mandatory.

Key Parameters

Substitute Part Grouping Explanation

Substitution is based strictly on electrical and mechanical compatibility: voltage rating, average rectified current, forward voltage at rated current, recovery characteristics, reverse leakage, capacitance, mounting type, package outline, and operating temperature range. Only parts meeting all these criteria or exceeding the main part specifications in voltage and maintaining equivalent package and electrical parameters are grouped as valid substitutes.

Key parameters for substitution:

• Voltage - DC Reverse (Vr) (Max)
• Current - Average Rectified (Io)
• Voltage - Forward (Vf) (Max) @ If
• Recovery Speed and Standard/Fast Classification
• Reverse Leakage Current at Stated Voltage
• Capacitance at Stated Test Conditions
• Package and Mounting Type
• Operating Temperature Range

Engineering Selection Recommendations

When the GS1KFL-TP is classified as obsolete, selection of the GS1MFL-TP as a substitute is justified based on equivalent or superior electrical characteristics, package type, and form factor. The GS1MFL-TP maintains ROHS3 and REACH compliance, MSL rating of 1 (unlimited), and EAR99 export classification. These compliance and availability factors support the technical justification for selecting GS1MFL-TP where the GS1KFL-TP is unavailable.

Frequently Asked Questions (FAQ)

Q1: Which parameters are critical for direct substitution of GS1KFL-TP in Diodes, Rectifiers applications?
Compatibility requires matching or exceeding rated voltage, current, package (DO-221AC, SMA-FL), forward voltage, reverse leakage, and operating temperature range.

Q2: Is the GS1MFL-TP compatible regarding package and mounting?
GS1MFL-TP uses the same DO-221AC (SMA-FL) surface mount package as GS1KFL-TP, ensuring mechanical compatibility.

Q3: Are there electrical differences to consider between GS1KFL-TP and GS1MFL-TP?
GS1MFL-TP offers a higher maximum DC reverse voltage (1000 V) while matching other key parameters such as current rating, forward voltage, and leakage current at test conditions.

Q4: Is compliance status relevant when selecting substitutes?
GS1MFL-TP maintains RoHS3 and REACH unaffected status. Such certifications ensure it meets current environmental and import/export regulations.

Q5: Can GS1MFL-TP be used as a direct replacement in legacy designs?
When mechanical outline, mounting, and electrical parameters are matched or exceeded as in GS1MFL-TP, it is categorized as a direct substitute for the GS1KFL-TP.
