SS210F-HF Equivalent & Substitute Parts Reference

Part Overview

The Comchip Technology SS210F-HF is a Schottky diode rated at 100 V reverse voltage and 2 A average rectified current, designed for surface mount applications in an SMAF (DO-214AC) package. The device features fast recovery (≤500 ns), low forward voltage drop, and low leakage current, making it suitable for high-speed switching and power rectification. The product is currently active and RoHS3 compliant, with high inventory availability. Finding alternative models is essential to ensure supply continuity, allow for second sourcing, and provide flexibility in procurement, especially when addressing inventory fluctuations or variations in packaging and compliance requirements.

Substitute Part Grouping Explanation

Substitution for the SS210F-HF has been determined strictly based on these key parameters: category (Diodes, Rectifiers), technology (Schottky), maximum reverse voltage (100 V), average rectified current rating (2 A), maximum forward voltage at 2 A (850 mV), fast recovery speed (≤500 ns, >200 mA), reverse leakage current, capacitance at specified conditions, mounting type (Surface Mount), package/case compatibility (DO-214AC, SMA/SMAF), operating temperature range, RoHS compliance, and moisture sensitivity level. Only parts matching these essential parameters are identified as parametric equivalents.

Engineering Selection Recommendations

All listed substitute parts are active, ROHS3 compliant, and possess an MSL of 1 (Unlimited). When selecting among these substitutes, confirm product status and compliance alignment with the SS210F-HF as outlined above. All substitutes with the DO-214AC, SMA or compatible package are valid equivalents within the parametric requirements. For specific qualification needs such as AEC-Q101 (automotive) or REACH status, refer to the individual substitute’s compliance fields. No additional technical selection criteria are to be considered beyond those explicitly listed.

Frequently Asked Questions (FAQ)

Q1: What criteria must a substitute for SS210F-HF meet?
A substitute must match the key electrical parameters (Schottky technology, 100 V max reverse voltage, 2 A average current, ≤850 mV forward voltage at 2 A, ≤500 ns fast recovery), have equal or lower reverse leakage current, and be supplied in a compatible surface mount DO-214AC, SMA or SMAF package. Compliance and MSL must also match.

Q2: Do differences in package marking or base part number affect substitution?
No, as long as the package type, case (DO-214AC, SMA/SMAF), and mounting method are equivalent per the documented parameters. Alternate supplier device package names are permitted if physically and electrically compatible.

Q3: Are all listed equivalents RoHS compliant?
Yes, all substitutes provided are specified as ROHS3 compliant.

Q4: If the capacitance field is unspecified for some components, does that prevent substitution?
If other primary parameters are aligned and capacitance is not a required maximum for the application use-case, the substitute remains valid within the constraints of this documentation.

Q5: Can these Schottky diode substitutes be used interchangeably in automated SMD assembly?
Yes, all parts in the list feature Surface Mount Device (SMD) configuration and compatible package outline as per DO-214AC, SMA, or SMAF.

Q6: Is AEC-Q101 qualification required for substitution?
AEC-Q101 is provided as a field for some substitutes. Use this field strictly as stated; if your application requires automotive qualification, refer to the “Grade” and “Qualification” fields for alternatives that hold this status.
