Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF1506SP-G is determined by strict equivalence across the following critical parameters:

• Voltage Rating: Peak reverse voltage of 600 V
• Current Rating: Average rectified current of 1.5 A
• Forward Voltage: Maximum forward voltage of 1.1 V at 1.5 A
• Diode Configuration: Single-phase bridge rectifier topology
• Mounting Technology: Surface mount with 4-SMD, Gull Wing package geometry
• Operating Temperature: -55°C to 150°C junction temperature range

All substitute parts listed maintain these electrical and mechanical specifications. Variations in reverse leakage current, product status, and manufacturer do not affect functional interchangeability within the defined parameter set. Parts are grouped into two categories: the manufacturer-recommended direct substitute from Comchip Technology, and parametric equivalents from alternative manufacturers that meet all specified electrical and mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: DF1506S-G

The DF1506S-G is the manufacturer-recommended substitute from Comchip Technology. This part maintains identical electrical specifications to the DF1506SP-G while offering active product status. The DF1506S-G is ROHS3 compliant with MSL 1 rating, providing superior compliance posture for new designs and procurement continuity.

Secondary Recommendations: DF1506S-E3/45 and DFL1506S-E3/45

Both Vishay General Semiconductor parts meet all electrical and mechanical requirements. The DF1506S-E3/45 and DFL1506S-E3/45 are active products with ROHS3 compliance and MSL 1 ratings. These parts offer the highest inventory availability (2558 and 985 units respectively) and are suitable for applications requiring established supply chain stability.

Parametric Equivalent: DBLS155G C1G and DBLS155GHC1G

Taiwan Semiconductor Corporation's DBLS155G C1G and DBLS155GHC1G are parametric equivalents meeting all specified electrical and mechanical parameters. The DBLS155GHC1G carries automotive-grade qualification (AEC-Q101), making it suitable for automotive applications requiring this certification. Both parts are ROHS3 compliant with MSL 1 ratings.

All substitute parts are interchangeable based on the defined parameter set. Selection should be based on supply chain availability, compliance requirements, and application-specific qualifications.

Frequently Asked Questions (FAQ)

Q: Can DF1506S-G directly replace DF1506SP-G in existing designs?

A: Yes. The DF1506S-G maintains identical electrical specifications (600 V, 1.5 A, 1.1 V forward voltage) and mechanical package (4-SMD, Gull Wing). Both parts operate across -55°C to 150°C. The primary difference is product status: DF1506SP-G is obsolete while DF1506S-G is active.

Q: What is the difference between the Comchip and Vishay parts?

A: DF1506S-G (Comchip) and DF1506S-E3/45 (Vishay) are functionally equivalent across all critical parameters. The Vishay part offers higher inventory availability and established long-term supply chain presence. Both are ROHS3 compliant and MSL 1 rated.

Q: Are the Taiwan Semiconductor DBLS155 parts suitable for all applications?

A: The DBLS155G C1G and DBLS155GHC1G meet all electrical and mechanical specifications for standard applications. The DBLS155GHC1G includes automotive-grade qualification (AEC-Q101) and is required for automotive applications. Both parts are ROHS3 compliant with MSL 1 ratings.

Q: Does reverse leakage current variation affect substitution?

A: Reverse leakage current varies across the substitute parts (2 µA to 10 µA at 600 V) but remains within acceptable ranges for single-phase bridge rectifier applications. All parts meet the maximum forward voltage specification of 1.1 V at 1.5 A, which is the primary parameter determining functional equivalence.

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

A: Yes. All substitute parts use 4-SMD, Gull Wing surface mount packaging with identical mechanical dimensions. PCB layout and assembly processes require no modification for substitution.

Q: What compliance certifications apply to these parts?

A: All active substitute parts are ROHS3 compliant and REACH unaffected. Moisture sensitivity level is 1 (Unlimited) for all parts, indicating no special moisture handling requirements. The DBLS155GHC1G carries additional AEC-Q101 automotive qualification.
