DF1510SP-G Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DF1510SP-G is a single-phase bridge rectifier manufactured by Comchip Technology, rated for 1 kV peak reverse voltage and 1.5 A average rectified current. This component is classified as obsolete, which necessitates identification of active equivalent and substitute parts for ongoing design support and procurement.

Bridge rectifiers in this electrical class are used in power supply circuits requiring full-wave rectification at moderate voltage and current levels. The obsolete status of the DF1510SP-G requires engineers to select from active alternatives that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF1510SP-G is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Matching Parameters:

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

Secondary Compatibility Parameters:

• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1.5 A (or lower)
• Current - Reverse Leakage @ Vr: 5 µA @ 1000 V (or lower)

Substitute parts are grouped into two categories:

Manufacturer Recommended Substitute: DF1510S-G from Comchip Technology maintains identical electrical specifications and is the direct active replacement with active product status.

Parametric Equivalents: DB157S (MDD), DBLS157G C1G (Taiwan Semiconductor Corporation), DBLS157GHC1G (Taiwan Semiconductor Corporation), DF1510S (HY Electronic), DF1510S-E3/45 (Vishay), and DFL1510S-E3/45 (Vishay) meet all critical matching parameters and operate within the same electrical envelope.

Engineering Selection Recommendations

Primary Recommendation: DF1510S-G

DF1510S-G from Comchip Technology is the manufacturer-recommended substitute. It maintains identical electrical specifications to the DF1510SP-G, carries active product status, and is ROHS3 compliant with MSL 1 rating. This part is the direct replacement for obsolete designs.

Secondary Recommendations for Parametric Equivalence:

DF1510S-E3/45 and DFL1510S-E3/45 (Vishay General Semiconductor - Diodes Division) are parametric equivalents with active status and ROHS3 compliance. Both maintain the 1.1 V forward voltage specification and 5 µA reverse leakage characteristic of the original part.

DB157S (MDD) is a parametric equivalent with superior reverse leakage performance (1 µA @ 1000 V) and lower forward voltage (1 V @ 1.5 A). This part is ROHS3 compliant and carries active product status.

DBLS157G C1G and DBLS157GHC1G (Taiwan Semiconductor Corporation) are parametric equivalents with active status and ROHS3 compliance. DBLS157GHC1G carries automotive-grade qualification (AEC-Q101), suitable for applications requiring automotive-level reliability.

DF1510S (HY Electronic) is a parametric equivalent with active status and ROHS3 compliance. REACH status is listed as vendor undefined; clarification with the supplier is required for applications subject to REACH regulations.

All substitute parts maintain the 4-SMD Gull Wing package configuration and surface mount mounting type, ensuring mechanical compatibility with existing PCB layouts designed for the DF1510SP-G.

Frequently Asked Questions (FAQ)

Q: Can DF1510S-G be used as a direct replacement for DF1510SP-G?

A: Yes. DF1510S-G is the manufacturer-recommended substitute from Comchip Technology. It maintains identical electrical specifications (1 kV, 1.5 A, 1.1 V forward voltage, 5 µA reverse leakage) and identical package configuration (4-SMD Gull Wing). The primary difference is product status: DF1510S-G is active while DF1510SP-G is obsolete.

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

A: Both are single-phase bridge rectifiers rated 1 kV / 1.5 A with identical electrical specifications. DF1510S-G is manufactured by Comchip Technology, while DF1510S-E3/45 is manufactured by Vishay General Semiconductor - Diodes Division. Both are ROHS3 compliant and carry active product status. Selection between them depends on supplier availability and procurement preferences.

Q: Is DB157S compatible with DF1510SP-G?

A: Yes. DB157S from MDD is a parametric equivalent meeting all critical electrical and mechanical requirements. It operates at 1 kV / 1.5 A in a 4-SMD Gull Wing package. DB157S exhibits superior reverse leakage performance (1 µA @ 1000 V versus 5 µA) and lower forward voltage (1 V @ 1.5 A versus 1.1 V), making it suitable for applications where lower power dissipation is beneficial.

Q: What is the difference between DBLS157G C1G and DBLS157GHC1G?

A: Both parts from Taiwan Semiconductor Corporation are parametric equivalents with identical electrical specifications (1 kV, 1.5 A, 1.1 V forward voltage, 2 µA reverse leakage). DBLS157GHC1G carries automotive-grade qualification (AEC-Q101), making it suitable for automotive applications requiring enhanced reliability standards. DBLS157G C1G is suitable for general industrial applications.

Q: Are all substitute parts ROHS3 compliant?

A: All substitute parts listed carry ROHS3 compliance. The original DF1510SP-G does not specify RoHS status. For applications requiring RoHS compliance, any of the listed substitutes are suitable.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: All substitute parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. This simplifies procurement and inventory management compared to parts with higher MSL ratings.

Q: Can DF1510S be used if REACH compliance is required?

A: DF1510S from HY Electronic lists REACH status as "Vendor Undefined." For applications requiring confirmed REACH compliance, select from DF1510S-G, DB157S, DBLS157G C1G, DBLS157GHC1G, DF1510S-E3/45, or DFL1510S-E3/45, all of which carry "REACH Unaffected" or "REACH Compliant" status.

Q: Are there packaging differences between substitute parts?

A: All substitute parts maintain the 4-SMD Gull Wing package configuration and surface mount mounting type, ensuring direct mechanical compatibility with PCB layouts designed for the DF1510SP-G. Packaging format (Tube or other) does not affect electrical or mechanical compatibility.

Q: Which substitute part has the lowest reverse leakage current?

A: DB157S exhibits the lowest reverse leakage current at 1 µA @ 1000 V, compared to 5 µA for the original DF1510SP-G. DBLS157G C1G and DBLS157GHC1G both exhibit 2 µA @ 1000 V reverse leakage. Lower reverse leakage reduces standby power consumption in applications with sustained reverse voltage conditions.

Q: Which substitute part is recommended for automotive applications?

A: DBLS157GHC1G from Taiwan Semiconductor Corporation carries automotive-grade qualification (AEC-Q101), making it the specified choice for automotive applications requiring enhanced reliability and qualification standards.
