Substitute Part Grouping Explanation

Substitution of the SS26FL is determined by strict equivalence in the following critical parameters:

Primary Substitution Criteria:

Voltage - DC Reverse (Vr) (Max): 60V
Current - Average Rectified (Io): 2A
Technology: Schottky
Mounting Type: Surface Mount
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Package Compatibility: Substitutes are grouped into two categories based on package type:

SOD-123F Package Equivalents – Direct mechanical and electrical interchange
Alternative Surface Mount Packages – Electrical equivalence with different package footprints (SOD-123W, DO-219AB)

Secondary Considerations: Forward voltage (Vf), reverse leakage current, and operating temperature range may vary within acceptable limits for the application. Parts with lower forward voltage or leakage current represent performance improvements. Parts with higher maximum junction temperature provide extended thermal margin.

Parts rated at 1A current (RB160MM-60TR, RB162MM-60TR, RB168MM-60TR) are not direct substitutes due to insufficient current rating and are excluded from primary equivalence.

Engineering Selection Recommendations

Direct SOD-123F Package Substitutes (Recommended for Pin-Compatible Replacement):

RB060M-60TR and RB060MM-60TR (Rohm Semiconductor): Both parts provide identical electrical specifications with 60V/2A rating, SOD-123F package compatibility, and active product status. Forward voltage is reduced to 610 mV, representing improved efficiency. Maximum junction temperature increased to 150°C. These parts are the primary recommendation for direct substitution.
RBR2MM60BTR (Rohm Semiconductor): Offers the lowest forward voltage at 580 mV @ 2A with SOD-123F package compatibility and active status. Suitable for applications prioritizing efficiency. Maximum junction temperature is 150°C.
SS2060FL_R1_00001 (Panjit International Inc.): Provides electrical equivalence with identical forward voltage (700 mV @ 2A) and SOD-123F package. Active product status with extended temperature range (-50°C ~ 150°C). Suitable for direct replacement with identical performance characteristics.
RB068MM-60TR (Rohm Semiconductor): Maintains 60V/2A specifications with SOD-123F package. Forward voltage is 765 mV with significantly reduced reverse leakage (1.5 µA). Active status with 150°C maximum junction temperature.

Alternative Package Substitutes (Requires PCB Layout Modification):

PMEG6020ELRX (Nexperia USA Inc.): Meets 60V/2A electrical requirements with SOD-123W package (different footprint). Active status with highest maximum junction temperature (175°C). Forward voltage is 760 mV. Requires PCB redesign for package accommodation.
SS2FH6-M3/H (Vishay General Semiconductor - Diodes Division): Meets 60V/2A electrical requirements with DO-219AB (SMF) package. Active status with 175°C maximum junction temperature. Forward voltage is 780 mV. Requires PCB redesign for package accommodation.

All recommended substitutes are RoHS3 compliant, REACH unaffected, and maintain MSL 1 (Unlimited) moisture sensitivity rating, ensuring compliance with environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can RB160MM-60TR or RB162MM-60TR be used as substitutes for SS26FL?

A: No. These parts are rated for 1A average rectified current, which is insufficient for the SS26FL's 2A specification. Using an undersized current rating creates thermal stress and reliability risk.

Q: What is the difference between RB060M-60TR and RB060MM-60TR?

A: Both parts are electrically identical with 60V/2A specifications and SOD-123F package. The difference lies in packaging format: RB060M-60TR is supplied in standard packaging, while RB060MM-60TR is supplied in Cut Tape (CT) & Digi-Reel® format. Selection depends on procurement and assembly requirements.

Q: Can PMEG6020ELRX replace SS26FL without PCB modification?

A: No. PMEG6020ELRX uses SOD-123W package while SS26FL uses SOD-123F package. These packages have different footprints and pin configurations. PCB layout modification is required for mechanical accommodation.

Q: Why does RBR2MM60BTR have lower forward voltage than SS26FL?

A: Forward voltage variation is inherent to Schottky diode manufacturing and design. RBR2MM60BTR's 580 mV @ 2A represents a different die design optimized for lower conduction losses. Both parts meet the 60V/2A specification and are electrically compatible.

Q: Is SS2060FL_R1_00001 a direct replacement for SS26FL?

A: Yes. SS2060FL_R1_00001 provides identical electrical specifications (60V/2A, 700 mV forward voltage) and SOD-123F package compatibility. Both parts are Schottky diodes with fast recovery characteristics. The primary difference is manufacturer (Panjit vs. onsemi) and active product status.

Q: What is the significance of reverse leakage current differences among substitutes?

A: Reverse leakage current affects power dissipation and circuit performance at high temperatures. Lower leakage (e.g., RB068MM-60TR at 1.5 µA) reduces standby power consumption. Higher leakage (e.g., PMEG6020ELRX at 300 nA) is negligible for most applications. Selection depends on circuit sensitivity to leakage current.

Q: Can I use SS2FH6-M3/H in a design originally specified for SS26FL?

A: Electrical substitution is valid (60V/2A Schottky diode). However, SS2FH6-M3/H uses DO-219AB package instead of SOD-123F, requiring PCB redesign. The part offers superior thermal performance (175°C max junction temperature) and lower reverse leakage (3 µA), making it suitable for demanding applications if layout modification is feasible.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are RoHS3 compliant and REACH unaffected, maintaining regulatory compliance with SS26FL.
