S1K-F Equivalent & Substitute Parts

Part Overview

The S1K-F is a general-purpose rectifier diode manufactured by SMC Diode Solutions, rated for 800 V DC reverse voltage with 1 A average rectified current in a surface mount SMA (DO-214AC) package. This component is classified as obsolete product status. Locating equivalent substitute parts is necessary due to the discontinued availability of the S1K-F, requiring selection from active product alternatives that maintain identical or equivalent electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts for the S1K-F are selected based on strict electrical and mechanical parameter equivalence. The substitution criteria are:

Primary Equivalence Parameters:

• Voltage - DC Reverse (Vr) (Max): 800 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1 A
• Reverse Recovery Time (trr): 2.5 µs
• Current - Reverse Leakage @ Vr: 5 µA @ 800 V
• Capacitance @ Vr, F: 15 pF @ 4 V, 1 MHz
• Package / Case: DO-214AC, SMA
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -65°C ~ 175°C

All substitute parts listed maintain these electrical specifications and mechanical compatibility, ensuring direct functional replacement in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

GS1K (SMC Diode Solutions) is the primary substitute for the S1K-F. Both parts are manufactured by SMC Diode Solutions and share identical electrical specifications and package configuration. The GS1K maintains active product status with ROHS3 compliance and REACH Affected designation, providing long-term availability and regulatory compliance for new designs.

S1K (YAGEO) is a parametric equivalent substitute. This part maintains the critical electrical parameters of 800 V reverse voltage, 1 A average rectified current, and 1.1 V forward voltage drop. The S1K is supplied in DO-214AC package with surface mount configuration. YAGEO S1K is ROHS3 compliant and carries MSL 1 rating. This part is suitable for applications where cross-manufacturer sourcing is acceptable.

Selection between GS1K and S1K should be based on supply chain requirements, procurement preferences, and any existing manufacturer qualification requirements within the application circuit.

Frequently Asked Questions (FAQ)

Q: Can the GS1K directly replace the S1K-F without circuit modification?

A: Yes. The GS1K maintains identical electrical specifications including 800 V reverse voltage rating, 1 A average rectified current, 1.1 V forward voltage drop at 1 A, 2.5 µs reverse recovery time, and 5 µA reverse leakage current at 800 V. The package configuration (DO-214AC, SMA) and mounting type (surface mount) are identical. No circuit modification is required.

Q: What is the difference between the GS1K and S1K (YAGEO)?

A: Both parts meet the primary electrical requirements of 800 V reverse voltage and 1 A average rectified current in DO-214AC package. The GS1K is manufactured by SMC Diode Solutions with complete specification documentation including reverse recovery time and reverse leakage current. The S1K from YAGEO is a parametric equivalent with the same voltage and current ratings but with limited detailed specification data provided. Both are ROHS3 compliant and carry MSL 1 rating.

Q: Are there packaging differences between these substitute parts?

A: The GS1K is supplied in Tape & Reel (TR) packaging. The S1K-F original packaging is not specified in the provided data. Both GS1K and S1K (YAGEO) use the same DO-214AC (SMA) component package, ensuring mechanical compatibility with existing PCB layouts and assembly processes.

Q: What compliance certifications apply to these substitute parts?

A: The GS1K is ROHS3 compliant with REACH Affected status. The S1K (YAGEO) is ROHS3 compliant. Both parts carry MSL 1 (Unlimited) moisture sensitivity level. All three parts (S1K-F, GS1K, and S1K YAGEO) share the same ECCN (EAR99) and HTSUS (8541.10.0080) classifications.

Q: Is the S1K-F still available for procurement?

A: The S1K-F is classified as obsolete product status. Active substitute parts GS1K and S1K (YAGEO) are recommended for new procurement and design applications.
