S5KC Equivalent & Substitute Parts

Part Overview

The S5KC is a general-purpose rectifier diode manufactured by SMC Diode Solutions, rated for 800 V DC reverse voltage and 5 A average rectified current in a surface mount SMC (DO-214AB) package. This diode is designed for standard recovery applications and is currently in active product status with RoHS3 compliance. Equivalent and substitute parts are identified based on matching electrical characteristics, mechanical compatibility, and package specifications to ensure functional interchangeability in circuit applications.

Substitute Part Grouping Explanation

Substitute parts for the S5KC are identified based on the following critical parameters that determine functional interchangeability:

Electrical Parameters:

Voltage - DC Reverse (Vr) (Max): 800 V
Current - Average Rectified (Io): 5 A
Voltage - Forward (Vf) (Max) @ If: 1.15 V @ 5 A
Speed: Standard Recovery >500ns, > 200mA (Io)
Current - Reverse Leakage @ Vr: 10 µA @ 800 V
Capacitance @ Vr, F: 40 pF @ 4V, 1MHz

Mechanical Parameters:

Package / Case: DO-214AB, SMC
Mounting Type: Surface Mount
Operating Temperature - Junction: -65°C to 150°C

Parts matching all electrical and mechanical parameters are classified as parametric equivalents and direct substitutes. Compliance status and product availability are secondary considerations for substitution eligibility.

Engineering Selection Recommendations

S5KC-13-F (Diodes Incorporated) is the primary substitute for the S5KC. This part is electrically and mechanically identical, maintains active product status, carries ROHS3 compliance certification, and is available in Tape & Reel packaging. Inventory availability is significantly higher at 15,400 pieces.

S5KC-13 (Diodes Incorporated) is a parametric equivalent with identical electrical and mechanical specifications. However, this part is discontinued at DiGi Electronics and does not meet RoHS3 compliance requirements. Selection of this part is appropriate only when RoHS compliance is not a design requirement and product discontinuation status is acceptable for the application timeline.

For new designs and applications requiring regulatory compliance, S5KC-13-F is the recommended substitute. For legacy systems or applications without compliance constraints, S5KC-13 remains functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Can S5KC-13-F be used as a direct replacement for S5KC in production?

A: Yes. S5KC-13-F matches all electrical parameters (800 V reverse voltage, 5 A average rectified current, 1.15 V forward voltage, standard recovery speed, 10 µA reverse leakage, 40 pF capacitance) and mechanical specifications (DO-214AB SMC package, surface mount, -65°C to 150°C operating range). Both parts are ROHS3 compliant and available in Tape & Reel packaging.

Q: What is the difference between S5KC-13 and S5KC-13-F?

A: Both parts are electrically and mechanically identical. The primary differences are: S5KC-13 is discontinued at DiGi Electronics and does not meet RoHS3 compliance, while S5KC-13-F is active and ROHS3 compliant. S5KC-13-F also has significantly higher inventory availability (15,400 pieces versus 1,081 pieces).

Q: Are there any package compatibility issues when substituting S5KC with S5KC-13-F?

A: No. Both the S5KC and S5KC-13-F use the DO-214AB SMC surface mount package. Pin configuration, footprint, and mounting requirements are identical. Both are supplied in Tape & Reel format for automated assembly.

Q: Does the S5KC-13 substitute work in applications requiring RoHS compliance?

A: No. S5KC-13 is RoHS non-compliant. Applications requiring RoHS3 certification must use S5KC-13-F or the original S5KC.

Q: What are the key electrical parameters that make these parts interchangeable?

A: The critical parameters are: 800 V DC reverse voltage rating, 5 A average rectified current, 1.15 V maximum forward voltage at 5 A, standard recovery speed (>500 ns), 10 µA reverse leakage current at 800 V, and 40 pF capacitance at 4 V and 1 MHz. All three parts match these specifications exactly.

Q: Can S5KC be substituted with parts from the secondary substitute list (STTH310S, S5K-E3/9AT, S5KL-TP, SMLJ60S10-TP, S10K)?

A: The secondary substitute list provided for S5KC-13 is not included in the primary substitution analysis for S5KC. Direct substitution eligibility is limited to S5KC-13 and S5KC-13-F, which match all specified electrical and mechanical parameters.
