Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DBLS157G C1G are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Diode Type: Single Phase
• Technology: Standard
• Voltage - Peak Reverse (Max): 1 kV
• Current - Average Rectified (Io): 1.5 A
• Mounting Type: Surface Mount
• Package / Case: 4-SMD, Gull Wing
• Operating Temperature Range: -55°C to 150°C (TJ)

Allowable Variation Parameters:

• Voltage - Forward (Vf) (Max) @ If: Up to 1.1 V @ 1.5 A
• Current - Reverse Leakage @ Vr: Up to 10 µA @ 1000 V

All substitute parts maintain identical peak reverse voltage, average rectified current, mounting configuration, and thermal operating range. Forward voltage and reverse leakage current remain within acceptable engineering tolerances for single-phase bridge rectifier applications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and full RoHS3 compliance, ensuring regulatory alignment with the original DBLS157G C1G component. Selection among substitute options is determined by availability and forward voltage characteristics:

DB157S (MDD): Offers the lowest forward voltage specification at 1 V @ 1.5 A and the lowest reverse leakage current at 1 µA @ 1000 V. This part provides superior electrical performance within the allowable parameter range.

DF1510S (HY Electronic): Maintains forward voltage and reverse leakage specifications within acceptable limits. Reverse leakage current reaches 10 µA @ 1000 V, representing the upper allowable threshold for this parameter class.

DFL1510S-E3/45 (Vishay General Semiconductor - Diodes Division): Provides intermediate reverse leakage performance at 5 µA @ 1000 V with forward voltage matching the main part specification. REACH compliance is confirmed as REACH Unaffected.

All substitute parts are qualified for direct replacement in applications requiring 1 kV, 1.5 A single-phase bridge rectification with surface mount integration and -55°C to 150°C thermal operation.

Frequently Asked Questions (FAQ)

Q: Can DB157S replace DBLS157G C1G in all applications?

A: DB157S is electrically equivalent across all critical parameters: 1 kV peak reverse voltage, 1.5 A average rectified current, -55°C to 150°C operating range, and 4-SMD Gull Wing surface mount package. Forward voltage is 1 V @ 1.5 A, which is lower than the main part specification of 1.1 V @ 1.5 A. Reverse leakage current is 1 µA @ 1000 V, also lower than the main part. Both parts are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between DF1510S and DFL1510S-E3/45?

A: Both parts share identical electrical ratings: 1 kV peak reverse voltage, 1.5 A average rectified current, 1.1 V forward voltage @ 1.5 A, and 4-SMD Gull Wing package. The primary difference is reverse leakage current: DF1510S specifies 10 µA @ 1000 V, while DFL1510S-E3/45 specifies 5 µA @ 1000 V. DFL1510S-E3/45 is manufactured by Vishay and carries REACH Unaffected status. DF1510S REACH status is listed as Vendor Undefined.

Q: Are all substitute parts available in the same packaging format?

A: All substitute parts use 4-SMD, Gull Wing surface mount package configuration, matching the DBLS157G C1G. DB157S, DF1510S, and DFL1510S-E3/45 are all qualified for direct PCB integration without package conversion or adapter requirements.

Q: Which substitute part has the best reverse leakage performance?

A: DB157S exhibits the lowest reverse leakage current at 1 µA @ 1000 V. DFL1510S-E3/45 provides intermediate performance at 5 µA @ 1000 V. DF1510S specifies 10 µA @ 1000 V. All values remain within acceptable engineering tolerances for single-phase bridge rectifier applications.

Q: Do all substitute parts meet RoHS3 compliance?

A: All substitute parts listed are ROHS3 compliant. Moisture Sensitivity Level is 1 (Unlimited) for all parts, indicating no moisture sensitivity restrictions during storage or handling.

Q: What is the operating temperature range for substitute parts?

A: All substitute parts operate across the identical temperature range of -55°C to 150°C (TJ), matching the DBLS157G C1G specification.
