Substitute Part Grouping Explanation

Substitution of the SS26HR5G is determined by the following critical parameters: reverse voltage rating (60 V minimum), average rectified current capacity (2 A minimum for direct equivalents), forward voltage drop (700 mV @ rated current), fast recovery speed characteristic (≤ 500ns), and surface mount package compatibility (DO-214AA SMB or equivalent form factor). Parts are grouped into three categories:

Parametric Equivalents maintain identical electrical specifications and package form, differing only in manufacturer or packaging format (tape & reel versus cut tape).

Similar Parts share the same 60 V reverse voltage and fast recovery characteristics but differ in current rating (1 A or 3 A) or package variant (SMA versus SMB). These parts are suitable for applications where current requirements differ from the original 2 A specification.

Automotive-Grade Substitutes carry AEC-Q101 qualification matching the original part's automotive certification, ensuring compliance with automotive reliability standards.

Engineering Selection Recommendations

Primary Equivalent (Direct Replacement): SS26H from Taiwan Semiconductor Corporation is the recommended direct replacement for SS26HR5G. This part maintains identical electrical specifications, automotive-grade AEC-Q101 qualification, identical package form (DO-214AA SMB), and matching junction temperature range (-55°C to 150°C). The part is currently in active production status with adequate inventory availability.

Automotive-Grade Alternatives: B260Q-13-F from Diodes Incorporated provides equivalent electrical performance with AEC-Q101 qualification, identical package, and extended lower temperature rating (-65°C versus -55°C). This part is suitable for applications requiring automotive compliance and is in active production.

Non-Automotive Alternatives: B260-13-F and CDBB260-HF provide equivalent 60 V, 2 A electrical specifications in DO-214AA SMB packages but lack AEC-Q101 automotive qualification. These parts are suitable for non-automotive applications where automotive certification is not required.

Package Variant Alternatives: B260A-13-F and SS26 (EVVO Semi) provide equivalent electrical specifications but in DO-214AC (SMA) package form. These are suitable only when SMA package compatibility exists in the design.

Current-Rated Alternatives: B160BQ-13-F (1 A) and B360BQ-13-F (3 A) maintain 60 V reverse voltage and fast recovery characteristics but differ in current capacity. B360BQ-13-F is suitable for applications requiring higher current capacity; B160BQ-13-F is suitable for lower current applications where 1 A capacity is sufficient.

Frequently Asked Questions (FAQ)

Q: Can SS26H be used as a direct replacement for SS26HR5G?

A: Yes. SS26H is a parametric equivalent with identical 60 V reverse voltage, 2 A current rating, 700 mV forward voltage drop, DO-214AA SMB package, and AEC-Q101 automotive qualification. The part is in active production status.

Q: What is the difference between DO-214AA (SMB) and DO-214AC (SMA) packages?

A: DO-214AA (SMB) and DO-214AC (SMA) are different surface mount package form factors. SMB is larger than SMA. Parts specified for SMB package cannot be directly substituted with SMA package variants without PCB layout modification. Conversely, SMA packages cannot be used in SMB footprints.

Q: Can B260Q-13-F replace SS26HR5G in automotive applications?

A: Yes. B260Q-13-F maintains identical electrical specifications (60 V, 2 A, 700 mV forward voltage), carries AEC-Q101 automotive qualification, and uses the same DO-214AA SMB package. The extended lower temperature rating (-65°C) provides additional margin for extreme cold environments.

Q: Why would I select B360BQ-13-F over SS26HR5G?

A: B360BQ-13-F is selected when the application requires higher current capacity (3 A versus 2 A) while maintaining the same 60 V reverse voltage rating and fast recovery characteristics. The part is AEC-Q101 qualified and uses the same DO-214AA SMB package.

Q: Can B160BQ-13-F be used in place of SS26HR5G?

A: B160BQ-13-F is not a direct replacement due to reduced current capacity (1 A versus 2 A). This part is suitable only for applications where the circuit current requirement does not exceed 1 A. The 60 V reverse voltage rating and fast recovery characteristics are maintained.

Q: What does AEC-Q101 qualification mean?

A: AEC-Q101 is an automotive electronics council qualification standard for discrete semiconductors. Parts carrying this qualification meet automotive reliability, quality, and performance requirements. For automotive applications, AEC-Q101 qualified parts are required.

Q: Are all listed substitute parts ROHS3 compliant?

A: Yes. All parts listed in this reference are ROHS3 compliant, meeting restriction of hazardous substances requirements for electronic components.

Q: What is the significance of fast recovery speed (≤ 500ns)?

A: Fast recovery speed indicates the diode's ability to switch from forward conduction to reverse blocking state within 500 nanoseconds. This characteristic is essential for high-frequency rectification applications and switching power supplies. All listed substitutes maintain this fast recovery specification.

Q: Can CDBB260-HF be used in automotive applications?

A: CDBB260-HF does not carry AEC-Q101 automotive qualification. While it provides equivalent electrical specifications and package form, it is not suitable for applications requiring automotive-grade components. Use B260Q-13-F or SS26H for automotive applications.

Q: What is the difference between cut tape and tape & reel packaging?

A: Cut tape (CT) packaging provides components in individual strips suitable for manual handling and smaller quantity orders. Tape & reel (TR) packaging provides components on continuous reels suitable for automated assembly equipment and larger production runs. Electrical specifications remain identical; packaging format affects handling and assembly methodology only.
