Substitute Part Grouping Explanation

Substitute parts for the CDBMTS260-HF are qualified based on the following electrical and mechanical criteria:

Primary Matching Criteria:

Voltage - DC Reverse (Vr) (Max): 60 V
Current - Average Rectified (Io): 2 A
Technology: Schottky
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
Mounting Type: Surface Mount
RoHS3 Compliance
MSL Level 1 (Unlimited)

Package Compatibility: Substitutes are grouped by surface mount package type (SOD-123S, SOD-123W, SOD-123FL). These packages are mechanically and electrically compatible for PCB assembly, though footprint verification is required during design integration.

Electrical Performance: All substitute parts maintain the 60V/2A rating and fast recovery switching speed. Forward voltage drop (Vf) and reverse leakage current (Ir) variations are within acceptable ranges for Schottky diode applications and do not affect functional interchangeability.

Engineering Selection Recommendations

PMEG6020ER,115 (Nexperia USA Inc.): This substitute offers superior forward voltage performance (530 mV vs. 700 mV at 2A) and lower reverse leakage current (150 µA vs. 500 µA), resulting in reduced power dissipation and improved efficiency. The SOD-123W package requires footprint verification. Operating temperature specification is maximum 150°C (no minimum specified). All regulatory certifications (ROHS3, MSL 1) are met. This part is suitable for applications prioritizing thermal efficiency.

SMD26PL-TP (Micro Commercial Co): This substitute maintains electrical performance identical to the main part (700 mV Vf, 500 µA Ir) with extended lower operating temperature range (-65°C vs. -55°C). The SOD-123FL package requires footprint verification. All regulatory certifications (ROHS3, MSL 1) are met. This part is suitable for applications requiring extended low-temperature operation or direct footprint compatibility with SOD-123F packages.

All substitute parts are active products with confirmed inventory availability and full compliance with ROHS3 and REACH requirements.

Frequently Asked Questions (FAQ)

Q: Can PMEG6020ER,115 be used as a direct replacement for CDBMTS260-HF?

A: PMEG6020ER,115 is electrically equivalent in voltage and current ratings. The primary difference is the package type (SOD-123W vs. SOD-123S). PCB footprint compatibility must be verified before substitution. The superior forward voltage performance (530 mV vs. 700 mV) may reduce power dissipation in the application.

Q: What is the difference between SOD-123S, SOD-123W, and SOD-123FL packages?

A: These are distinct surface mount package variants within the SOD-123 family. Each has different physical dimensions and PCB footprints. Mechanical compatibility requires verification against PCB design specifications. All three packages are surface mount types suitable for automated assembly.

Q: Are all three parts RoHS3 compliant?

A: Yes. CDBMTS260-HF, PMEG6020ER,115, and SMD26PL-TP are all ROHS3 Compliant with MSL Level 1 (Unlimited moisture sensitivity). All parts are REACH Unaffected.

Q: Which substitute has the lowest power dissipation?

A: PMEG6020ER,115 exhibits the lowest forward voltage drop (530 mV @ 2A) compared to both the main part and SMD26PL-TP (700 mV @ 2A each). Lower forward voltage results in reduced power dissipation in rectification applications.

Q: What is the operating temperature range for each part?

A: CDBMTS260-HF: -55°C to 150°C; PMEG6020ER,115: 150°C maximum (no minimum specified); SMD26PL-TP: -65°C to 150°C. Application thermal requirements determine the appropriate selection.

Q: Can these parts be used interchangeably in existing designs?

A: Electrical interchangeability is confirmed for all three parts at the 60V/2A rating. Physical interchangeability requires PCB footprint verification for the specific package type. Design validation is necessary before production implementation.
