SS26-HF Equivalent & Substitute Parts Reference

Part Overview

The Comchip Technology SS26-HF is a surface-mount Schottky diode, cataloged under Diodes, Rectifiers, and commonly supplied in DO-214AC (SMA) packaging. It offers a maximum reverse voltage of 60 V and an average rectified current of 2A, with fast recovery characteristics meeting a maximum forward voltage of 700 mV at 2A. The part is RoHS3 compliant, moisture sensitivity level 1, and is in active production status. Identifying interchangeable parts is required to ensure continuity of supply, facilitate second sourcing, and maintain compatibility in manufacturing environments—especially when inventory constraints or supply chain optimization necessitate alternative sourcing.

Substitute Part Grouping Explanation

Substitute parts for the SS26-HF are determined strictly by matching all critical electrical and mechanical parameters: diode type (Schottky), reverse voltage rating (60 V), average rectified current (2A), maximum forward voltage at specified current (700 mV @ 2A), recovery speed, leakage current at reverse voltage, capacitance, package type (DO-214AC/SMA), mounting type, operating temperature range, RoHS compliance, MSL, and REACH status. Only parts with congruent specifications in these required fields are classified as parametric equivalents.

Engineering Selection Recommendations

All substitute Schottky diodes listed match the essential electrical, mechanical, and compliance parameters of the SS26-HF, including voltage ratings, current capabilities, package type, and RoHS3 compliance. All options offer an active product status and meet Moisture Sensitivity Level 1. Verify REACH requirements based on documentation provided for each substitute if REACH compliance is a design constraint.

Frequently Asked Questions (FAQ)

Q1: What determines if a Schottky diode is an exact substitute for the SS26-HF?
A1: Exact substitution requires matching electrical ratings (reverse voltage, forward current, forward voltage drop, recovery speed), package type (DO-214AC/SMA), mounting style (surface mount), and compliance status (RoHS, MSL).

Q2: Are there differences in reverse leakage current or capacitance among the substitutes?
A2: Yes. Substitute parts may have lower or different maximum reverse leakage currents and capacitance values. All substitutes stay within or below the maximum ratings specified for the SS26-HF.

Q3: Are mechanical dimensions and footprint compatible for all substitutes listed?
A3: Each listed substitute uses the DO-214AC (SMA) package, ensuring direct footprint compatibility.

Q4: Are compliance and RoHS status uniform across all substitute part numbers?
A4: Each part is RoHS3 compliant and rated MSL 1 (unlimited), ensuring suitability for most lead-free and standard assembly processes.

Q5: How does REACH status affect the selection?
A5: The SS26-HF and most substitutes are REACH Unaffected; one substitute lists Vendor Undefined for REACH. Confirm documentation compliance if REACH is a design or procurement requirement.
