DF08-G Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DF08-G is a single-phase bridge rectifier manufactured by Comchip Technology, rated for 800 V peak reverse voltage and 1 A average rectified current. This component is designed for through-hole mounting applications requiring standard bridge rectification in industrial and consumer electronics. The part maintains active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified based on matching electrical performance parameters and mechanical compatibility within the through-hole 4-EDIP package family.

Substitute Part Grouping Explanation

Substitute parts for the DF08-G are qualified based on the following criteria:

Full Electrical Equivalents (800 V Rating):

• DB106-BP (Micro Commercial Co): Matches all critical electrical parameters including 800 V peak reverse voltage, 1 A average rectified current, 1.1 V forward voltage, and 10 µA reverse leakage at rated voltage. Identical operating temperature range and package configuration.

Voltage-Reduced Equivalent (600 V Rating):

• DF06 (HY Electronic): Maintains matching current rating (1 A), forward voltage (1.1 V @ 1 A), reverse leakage (10 µA @ 600 V), operating temperature range, and package form factor. Peak reverse voltage is reduced to 600 V, limiting application scope to lower voltage circuits.

All substitute parts share identical mounting type (through hole), package dimensions (4-EDIP), and thermal operating range. Substitution compatibility is determined by application voltage requirements and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute - DB106-BP: DB106-BP from Micro Commercial Co provides complete electrical and mechanical equivalence to DF08-G. Both components maintain 800 V peak reverse voltage rating, identical current and voltage specifications, and matching RoHS3 compliance with unlimited moisture sensitivity. Selection of DB106-BP requires no circuit redesign or thermal management adjustments.

Secondary Substitute - DF06: DF06 from HY Electronic is suitable only for applications where peak reverse voltage requirements do not exceed 600 V. While maintaining identical current capacity, forward voltage characteristics, and operating temperature range, the reduced voltage rating restricts its use to lower voltage rectification circuits. RoHS3 compliance is confirmed; REACH status is vendor undefined for this part.

All substitute parts maintain active product status and are available in production quantities.

Frequently Asked Questions (FAQ)

Q: Can DB106-BP directly replace DF08-G without circuit modification? A: Yes. DB106-BP matches all electrical parameters (800 V, 1 A, 1.1 V forward voltage) and mechanical specifications (4-EDIP package, through-hole mounting). No circuit redesign is required.

Q: Under what conditions can DF06 be used as a substitute? A: DF06 is suitable only for applications where the maximum reverse voltage does not exceed 600 V. Current rating (1 A), forward voltage (1.1 V @ 1 A), and operating temperature range (-55°C ~ 150°C) are identical to DF08-G. Applications requiring 800 V rating must use DB106-BP or DF08-G.

Q: Are all substitute parts RoHS3 compliant? A: DB106-BP and DF08-G are both confirmed ROHS3 Compliant. DF06 is ROHS3 Compliant. All three parts meet RoHS3 requirements.

Q: Do substitute parts require different PCB footprints? A: No. All three parts use identical 4-EDIP package dimensions (0.321", 8.15mm) and through-hole mounting configuration. PCB footprints are interchangeable.

Q: What is the moisture sensitivity rating for these components? A: All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: Are there inventory considerations for substitute selection? A: DB106-BP has higher inventory availability (5744 Pcs) compared to DF08-G (850 Pcs) and DF06 (1120 Pcs). Inventory levels may influence procurement decisions based on project timelines.
