DF02SP-HF Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DF02SP-HF is a single-phase bridge rectifier manufactured by Comchip Technology, rated for 200 V peak reverse voltage and 1 A average rectified current. This component is classified as obsolete, necessitating identification of active equivalent and substitute parts for ongoing design support and procurement. The DF02SP-HF operates across a temperature range of -55°C to 150°C and is packaged in a 4-SMD Gull Wing surface mount configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF02SP-HF is determined by electrical and mechanical parameter equivalence. The critical parameters for substitution are:

• Voltage Rating: Peak reverse voltage of 200 V
• Current Rating: Average rectified current of 1 A
• Forward Voltage: Maximum 1.1 V at 1 A
• Temperature Range: -55°C to 150°C operating junction temperature
• Package Configuration: 4-SMD Gull Wing surface mount

All substitute parts listed maintain these core electrical specifications and physical packaging requirements. Reverse leakage current values vary among substitutes but remain within acceptable operational parameters for this application category. Substitute parts are classified into two categories: manufacturer-recommended active equivalents and parametric equivalents from alternative manufacturers.

Engineering Selection Recommendations

Primary Recommendation: DF02S-HF

The DF02S-HF is the manufacturer-recommended active equivalent from Comchip Technology. This part maintains identical electrical specifications and packaging to the obsolete DF02SP-HF, providing direct functional replacement with active product status and ongoing manufacturer support.

Secondary Recommendations: DF02S-E3/45 and DF02SA-E3/45

Both Vishay General Semiconductor parts (DF02S-E3/45 and DF02SA-E3/45) are parametric equivalents with active product status. These parts meet all core electrical and mechanical requirements. Both carry ROHS3 compliance and REACH unaffected status. The DF02S-E3/45 offers the highest inventory availability at 3480 pieces.

Alternative Recommendation: DBLS103GHC1G

The DBLS103GHC1G from Taiwan Semiconductor Corporation is a parametric equivalent with automotive-grade qualification (AEC-Q101) and active product status. This part is suitable for applications requiring automotive-level reliability and traceability. ROHS3 compliance and REACH unaffected status are provided.

General Alternative: DBLS103G C1G

The DBLS103G C1G is a parametric equivalent with active product status and ROHS3 compliance. This part provides functional equivalence without automotive qualification.

All substitute parts are surface mount components in 4-SMD Gull Wing packaging, maintaining mechanical compatibility with the original DF02SP-HF footprint.

Frequently Asked Questions (FAQ)

Q: Can DF02S-HF directly replace DF02SP-HF in existing designs?

A: Yes. The DF02S-HF maintains identical electrical specifications (200 V, 1 A, 1.1 V forward voltage) and physical packaging (4-SMD Gull Wing). Both are manufactured by Comchip Technology and operate across the same temperature range (-55°C to 150°C).

Q: What is the difference between the Comchip DF02S-HF and Vishay DF02S-E3/45?

A: Both parts meet identical core electrical specifications and packaging requirements. The primary differences are manufacturer, reverse leakage current (10 µA for DF02S-HF versus 5 µA for DF02S-E3/45), and packaging format (DF02S-E3/45 is supplied in tube packaging). Both are active products with ROHS3 compliance.

Q: Are the Taiwan Semiconductor DBLS103 parts suitable replacements?

A: Yes. The DBLS103G C1G and DBLS103GHC1G maintain all critical electrical parameters and 4-SMD Gull Wing packaging. The DBLS103GHC1G includes automotive-grade qualification (AEC-Q101) for applications requiring this certification. Reverse leakage current is lower at 2 µA compared to the original 10 µA.

Q: What is the significance of the AEC-Q101 qualification on DBLS103GHC1G?

A: AEC-Q101 qualification indicates the part meets automotive industry reliability and quality standards. This certification is required for automotive applications but is not necessary for general industrial or consumer applications.

Q: Do all substitute parts have the same moisture sensitivity level?

A: The Vishay parts (DF02S-E3/45 and DF02SA-E3/45) and Taiwan Semiconductor parts (DBLS103G C1G and DBLS103GHC1G) specify Moisture Sensitivity Level (MSL) 1 (Unlimited). The original DF02SP-HF does not provide MSL specification in the available data.

Q: Which substitute part has the highest inventory availability?

A: The Vishay DF02S-E3/45 has the highest inventory at 3480 pieces, followed by the Taiwan Semiconductor DBLS103G C1G at 993 pieces.

Q: Are all substitute parts ROHS3 compliant?

A: The Vishay parts (DF02S-E3/45 and DF02SA-E3/45) and Taiwan Semiconductor parts (DBLS103G C1G and DBLS103GHC1G) are ROHS3 compliant. The original DF02SP-HF and Comchip DF02S-HF do not provide RoHS status in the available data.

Q: Can I use DF02SA-E3/45 instead of DF02S-E3/45?

A: Yes. Both Vishay parts maintain identical electrical specifications and packaging. The DF02SA-E3/45 has lower inventory (652 pieces) compared to DF02S-E3/45 (3480 pieces).
