Substitute Part Grouping Explanation

Substitute parts for the RDBLS207GH are identified through parametric equivalence matching. The substitution logic is based on the following critical parameters that must remain constant across all equivalent parts:

Voltage - Peak Reverse (Max): 1 kV
Current - Average Rectified (Io): 2 A
Voltage - Forward (Vf) (Max) @ If: 1.15 V @ 2 A
Current - Reverse Leakage @ Vr: 2 µA @ 1000 V
Operating Temperature Range: -55°C ~ 150°C (TJ)
Mounting Type: Surface Mount
Package / Case: 4-SMD, Gull Wing
Supplier Device Package: DBLS
RoHS Status: ROHS3 Compliant
Moisture Sensitivity Level (MSL): 1 (Unlimited)

All identified substitute parts maintain identical electrical performance characteristics and mechanical compatibility. Parts are grouped as parametric equivalents when all specified parameters align without deviation.

Engineering Selection Recommendations

All three parts—RDBLS207GH, DBLS207G, and DBLS207GH—are Active status components manufactured by Taiwan Semiconductor Corporation with identical electrical and mechanical specifications. Selection between these parts is based on availability and compliance requirements:

RDBLS207GH carries automotive-grade qualification under AEC-Q101 standard with 748 units in stock. This part is specified for applications requiring automotive-level reliability and traceability.

DBLS207G is a parametric equivalent without automotive-grade designation, with 2800 units in stock. This part is suitable for general industrial applications where automotive qualification is not required.

DBLS207GH carries automotive-grade qualification under AEC-Q101 standard with 4078 units in stock. This part provides the same automotive-level reliability as RDBLS207GH with higher inventory availability.

All parts maintain ROHS3 compliance, unlimited moisture sensitivity level (MSL 1), and REACH unaffected status. Selection should prioritize application requirements for automotive qualification and current inventory levels.

Frequently Asked Questions (FAQ)

Q: Can DBLS207G be used as a direct substitute for RDBLS207GH in automotive applications?

A: DBLS207G matches all electrical and mechanical parameters but lacks automotive-grade qualification and AEC-Q101 certification. Use only in non-automotive applications or where automotive qualification is not specified.

Q: What is the difference between RDBLS207GH and DBLS207GH?

A: Both parts are identical in electrical specifications, mechanical packaging, and automotive-grade qualification under AEC-Q101. The primary difference is inventory availability: DBLS207GH has 4078 units in stock compared to 748 units for RDBLS207GH.

Q: Are all three parts compatible with the same PCB layout?

A: Yes. All three parts use identical 4-SMD Gull Wing packaging in the DBLS supplier device package format, ensuring mechanical and electrical compatibility with the same PCB footprint and solder reflow process.

Q: What compliance certifications apply to all substitute parts?

A: All parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. RDBLS207GH and DBLS207GH carry additional AEC-Q101 automotive qualification.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. All three parts operate across the identical temperature range of -55°C to 150°C (TJ), supporting high-temperature industrial and automotive environments.

Q: What is the moisture sensitivity level for these bridge rectifiers?

A: All parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or assembly processes.
