Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DBL103G C1G are identified based on electrical and mechanical parameter equivalence. The substitution logic is structured around the following critical parameters:

Electrical Parameters:

• Voltage - Peak Reverse (Max): 200 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1 A
• Current - Reverse Leakage @ Vr: 2 µA @ 200 V
• Operating Temperature Range: -55°C ~ 150°C (TJ)

Mechanical Parameters:

• Mounting Type: Through Hole
• Package / Case: 4-DIP (0.300", 7.62mm)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Parts meeting all these parameters are classified as direct equivalents or parametric equivalents. Variations in product status, grade qualification, or manufacturing revision do not affect electrical or mechanical substitutability when all specified parameters remain identical.

Engineering Selection Recommendations

DBL103G (Direct Equivalent)

The DBL103G is a direct manufacturer equivalent to the DBL103G C1G. All electrical parameters, mechanical specifications, and compliance certifications are identical. The primary distinction is product status: DBL103G is currently active with 685 pieces in stock, whereas the DBL103G C1G is discontinued. This part is suitable for direct substitution in all applications where the original part was specified.

DBL103GH (Parametric Equivalent)

The DBL103GH meets all electrical and mechanical parameter requirements of the DBL103G C1G. This part carries automotive-grade qualification (AEC-Q101) and is designated for automotive applications. The DBL103GH is currently active with 900 pieces in stock. Selection of this part is appropriate when automotive-grade reliability and qualification are required or when enhanced quality assurance standards are mandated by application requirements. The parametric equivalence ensures functional compatibility in all circuit configurations where the original part operates.

Both substitute parts maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring compatibility with modern manufacturing and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can the DBL103G be used as a direct replacement for the DBL103G C1G?

A: Yes. The DBL103G is a direct equivalent with identical electrical parameters (200 V peak reverse voltage, 1 A average rectified current, 1.1 V forward voltage drop), identical operating temperature range (-55°C to 150°C), and identical 4-DIP through-hole package configuration. The only difference is product status; DBL103G is currently active while DBL103G C1G is discontinued.

Q: What is the difference between DBL103G and DBL103GH?

A: Both parts are parametric equivalents with identical electrical specifications and package configuration. The DBL103GH carries automotive-grade qualification (AEC-Q101) and is designated for automotive applications. Selection between these parts depends on application requirements and quality assurance standards.

Q: Are all substitute parts RoHS compliant?

A: Yes. Both DBL103G and DBL103GH are ROHS3 compliant and carry unlimited moisture sensitivity rating (MSL 1), matching the compliance profile of the original DBL103G C1G.

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

A: Yes. All three parts use the identical 4-DIP (0.300", 7.62mm) through-hole package configuration. PCB footprints, lead spacing, and mounting requirements are identical, enabling direct substitution without design modification.

Q: What are the key electrical parameters that define substitutability?

A: Substitutability is determined by: peak reverse voltage (200 V), average rectified current (1 A), forward voltage drop (1.1 V @ 1 A), reverse leakage current (2 µA @ 200 V), and operating temperature range (-55°C to 150°C). All substitute parts maintain these specifications.

Q: Is the automotive qualification of DBL103GH required for non-automotive applications?

A: No. For standard industrial and consumer applications, the DBL103G provides full electrical and mechanical equivalence without automotive qualification. Selection of DBL103GH is driven by specific application requirements for automotive-grade reliability and AEC-Q101 certification.
