Substitute Part Grouping Explanation

Substitute parts for the SS26HM3_A/H are classified into two categories based on electrical and mechanical parameter alignment:

Parametric Equivalents share identical or functionally equivalent electrical specifications across all critical parameters: 60 V reverse voltage rating, 2 A average rectified current, 700 mV forward voltage drop at 2 A, fast recovery speed characteristics, DO-214AA/SMB package compatibility, and automotive-grade AEC-Q101 qualification. These parts are direct functional replacements.

Similar Parts maintain the same voltage, current, and package specifications but may differ in secondary parameters such as reverse leakage current magnitude, capacitance characteristics, or operating temperature range minimums. These parts are suitable for applications where the primary electrical ratings are the determining factors.

Substitution eligibility is determined by:

Voltage - DC Reverse (Vr) (Max): 60 V
Current - Average Rectified (Io): 2 A
Voltage - Forward (Vf) (Max) @ If: 700 mV @ 2 A
Package / Case: DO-214AA, SMB
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
Mounting Type: Surface Mount

Engineering Selection Recommendations

Parametric Equivalents (Direct Replacements):

SS26HE3_A/H and SS26HE3_A/I are parametric equivalents manufactured by Vishay General Semiconductor - Diodes Division. These parts maintain identical electrical specifications, automotive-grade classification, and AEC-Q101 qualification to the SS26HM3_A/H. Both are supplied in Tape & Reel packaging and are suitable for direct substitution in applications requiring automotive-qualified Schottky rectifiers.

Automotive-Qualified Alternatives:

B260Q-13-F (Diodes Incorporated) is an automotive-grade, AEC-Q101 qualified alternative supplied in Tape & Reel packaging. This part meets the primary electrical specifications and temperature range requirements. The reverse leakage current is specified at 500 µA @ 60 V, which is higher than the main part's 400 µA specification but remains within acceptable operating parameters for Schottky diode applications.

SS26H (Taiwan Semiconductor Corporation) is an automotive-qualified alternative with AEC-Q101 certification. This part maintains identical electrical specifications with the exception of the minimum operating temperature, which is -55°C compared to -65°C for the main part. Selection of this part is appropriate for applications where the -55°C minimum temperature is acceptable.

General-Purpose Alternatives:

B260-13-F (Diodes Incorporated) and CMSH2-60 TR13 PBFREE (Central Semiconductor Corp) are parametric equivalents that meet the primary electrical specifications and temperature range. These parts are not specified with automotive-grade classification or AEC-Q101 qualification. Selection of these parts is appropriate for non-automotive applications or where automotive qualification is not a design requirement.

Frequently Asked Questions (FAQ)

Q: Can SS26HE3_A/H be used as a direct replacement for SS26HM3_A/H?

A: Yes. SS26HE3_A/H is a parametric equivalent manufactured by the same supplier (Vishay General Semiconductor - Diodes Division) with identical electrical specifications, automotive-grade classification, AEC-Q101 qualification, and DO-214AA/SMB package compatibility.

Q: What is the difference between B260-13-F and B260Q-13-F?

A: Both parts are manufactured by Diodes Incorporated and share identical electrical specifications. The primary differences are packaging format (B260-13-F is supplied in Cut Tape & Digi-Reel®; B260Q-13-F is supplied in Tape & Reel) and qualification status (B260Q-13-F carries automotive-grade classification and AEC-Q101 qualification, while B260-13-F does not specify these certifications).

Q: Is the SS26H from Taiwan Semiconductor Corporation suitable for automotive applications?

A: SS26H carries automotive-grade classification and AEC-Q101 qualification. The part is suitable for automotive applications with the exception that its minimum operating temperature is -55°C rather than -65°C. Verify that the application's temperature requirements are compatible with this specification.

Q: What does the reverse leakage current difference between 400 µA and 500 µA mean for circuit performance?

A: Reverse leakage current is the small current that flows through the diode when reverse biased. The difference between 400 µA and 500 µA represents a 25% increase in leakage. For most rectifier applications, this difference is negligible. Verify leakage current specifications against application requirements for low-power or high-impedance circuits.

Q: Can I substitute a non-automotive-qualified part in an automotive application?

A: Automotive applications typically require components qualified to AEC-Q101 or equivalent standards. B260-13-F and CMSH2-60 TR13 PBFREE do not specify automotive qualification. Substitution of non-qualified parts in automotive designs requires design review and approval by the responsible engineering authority.

Q: Are all substitute parts available in the same packaging format?

A: No. SS26HM3_A/H, SS26HE3_A/H, SS26HE3_A/I, SS26H, B260Q-13-F, and CMSH2-60 TR13 PBFREE are supplied in Tape & Reel (TR) packaging. B260-13-F is supplied in Cut Tape (CT) & Digi-Reel® packaging. Verify packaging compatibility with assembly equipment and procurement requirements before selection.

Q: What is the significance of the DO-214AA/SMB package designation?

A: DO-214AA and SMB are equivalent designations for the same surface mount package. All listed parts use this package, ensuring mechanical and electrical compatibility on printed circuit boards designed for DO-214AA/SMB components.

Q: Does ROHS3 compliance apply to all substitute parts?

A: Yes. All listed parts, including the main part SS26HM3_A/H and all substitute parts, are specified as ROHS3 Compliant. All parts are also REACH Unaffected and carry Moisture Sensitivity Level (MSL) 1 (Unlimited).
