Equivalent & Substitute Parts for SCS208AGC – Diodes, Rectifiers

Part Overview

The SCS208AGC by Rohm Semiconductor is a silicon carbide (SiC) Schottky diode rated for 650 V, 8 A, provided in a TO-220AC through-hole package. The product is classified as obsolete, and its active inventory is limited. For maintenance, repair, or new designs requiring continuity of supply with equivalent electrical and mechanical characteristics, identification of appropriate substitute parts is required.

Substitute Part Grouping Explanation

Substitute selections are strictly based on matching or exceeding the following key parameters: technology (SiC Schottky), maximum reverse voltage (650 V), average rectified current (Io), forward voltage (Vf) at comparable current, reverse recovery time (trr), mounting type (through-hole), and package compatibility (TO-220-2 or equivalent through-hole packages). Compliance requirements (RoHS and REACH) align with regulatory obligations and supply assurance.

Engineering Selection Recommendations

Substitute part selection should be based on product status (active vs. obsolete), compliance with ROHS3 and REACH, and package compatibility as specified. All listed substitutes are ROHS3 compliant and REACH unaffected, meeting regulatory standards for continued use.

Frequently Asked Questions (FAQ)

Q: What parameters are critical for diode rectifier substitution in the SiC Schottky category?
A: Critical parameters include technology type, maximum reverse voltage, average rectified current, forward voltage drop at rated current, reverse recovery time, mounting type, and package/case format.

Q: Are the mechanical packages of the substitutes directly compatible with the SCS208AGC?
A: All substitutes listed are provided in TO-220-2 through-hole packages or supplier equivalents, ensuring compatibility with the original device footprint.

Q: How does product status affect substitute selection?
A: Active product status ensures ongoing availability and support. The SCS208AGC is obsolete, while all substitutes are currently active.

Q: Is regulatory compliance consistent across all listed parts?
A: All substitutes are ROHS3 compliant and REACH unaffected, matching the compliance parameters of the SCS208AGC.

Q: Can the specified substitute parts be used without modification for the same application?
A: Substitution is determined strictly by electrical parameters, mounting type, and package; only parts meeting all listed criteria are included.
