SS310C-HF Equivalent & Substitute Parts Reference

Part Overview

The Comchip Technology SS310C-HF is a surface-mount Schottky diode in the DO-214AB (SMC) package, rated for 100V reverse voltage and 3A average rectified current. The part is categorized under diodes, rectifiers, and remains active with RoHS3 compliance and MSL 1 rating. Alternate models may be needed due to supply chain variation, discontinued status, or broader inventory management requirements.

Substitute Part Grouping Explanation

Substitute parts are identified solely using the following electrical and mechanical parameters: Schottky technology, 100 V maximum reverse voltage, 3A average rectified current, maximum forward voltage of 850 mV at 3A, equivalent or superior speed (<500ns recovery), compatible surface-mount DO-214AB (SMC) package, operating temperature of -55°C to 150°C, and required compliance standards (RoHS3). Only diodes meeting all these criteria are listed as parametric equivalents.

Engineering Selection Recommendations

Selection between SS310C-HF, S310, SK310-TP, and SS310 V7G should consider only the product status, RoHS compliance, and MSL ratings as provided. SS310C-HF, SK310-TP, and SS310 V7G are listed as ROHS3 compliant and have MSL 1 (Unlimited). S310 has active status, but no explicit RoHS or MSL detail. SS310 V7G is discontinued at select distributors, but technical parameters are fully provided.

Frequently Asked Questions (FAQ)

Q1: What determines electrical compatibility for SS310C-HF substitutes?
A1: Electrical compatibility is defined by Schottky technology, Vr (Max) 100V, Io 3A, Vf (Max) of 850 mV @ 3A, and fast recovery time ≤ 500ns.

Q2: Are all substitute parts guaranteed to fit mechanically?
A2: All listed substitutes use the DO-214AB (SMC) surface-mount package and are designed for direct mechanical interchange in this category.

Q3: What compliance factors are relevant for substitute selection?
A3: Selection is based on provided RoHS3 status and Moisture Sensitivity Level (MSL) per part data.

Q4: Does the reverse leakage parameter vary among substitutes?
A4: SS310C-HF has 300 µA @ 100 V; S310 and SK310-TP have 500 µA @ 100 V; SS310 V7G has 100 µA @ 100 V.

Q5: Is there any difference in operating temperature ranges among the substitutes?
A5: All parts are rated -55°C to 150°C junction temperature.

Q6: How do discontinued product statuses affect substitution?
A6: Discontinued status means inventory availability may differ, but this does not affect parametric equivalence if technical parameters are matched as provided.
