DB204L-BP Bridge Rectifier Single Phase Standard 400 V Through Hole

Part Overview

The DB204L-BP is a single-phase bridge rectifier manufactured by Micro Commercial Co, designed for 400 V peak reverse voltage applications. This component features a 2 A average rectified current rating and operates across a temperature range of -55°C to 150°C. The part is mounted through-hole in a 4-EDIP package configuration.

The DB204L-BP is classified as obsolete. Locating equivalent substitute components is necessary to support ongoing maintenance, repair, and new design requirements where this part is specified or where inventory depletion occurs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DB204L-BP is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Diode Type: Single Phase (must match)
• Technology: Standard (must match)
• Current - Average Rectified (Io): 2 A (must match or exceed)
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 2 A (must match or be lower)
• Operating Temperature Range: -55°C to 150°C (must match or exceed)

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole (must match)
• Package / Case: 4-EDIP (0.321", 8.15mm) (must match)
• Supplier Device Package: DBL-1 (must match)

Voltage Rating Consideration: The DB204L-BP operates at 400 V peak reverse voltage. Substitute parts with higher voltage ratings (such as 1 kV) are electrically compatible for use in 400 V applications, as they provide additional safety margin and do not degrade performance in lower-voltage circuits.

Parameter Comparison

Engineering Selection Recommendations

The DB207L-BP is a direct substitute for the DB204L-BP based on the following factors:

Electrical Equivalence: All critical electrical parameters match between the two parts. The DB207L-BP maintains identical current ratings (2 A average rectified), forward voltage characteristics (1.1 V @ 2 A), and operating temperature range (-55°C to 150°C). The higher peak reverse voltage rating (1 kV versus 400 V) does not compromise functionality in 400 V applications and provides additional design margin.

Mechanical Compatibility: Both parts share identical through-hole mounting configuration, 4-EDIP package dimensions (0.321", 8.15mm), and DBL-1 supplier device package designation. Direct board-level substitution is supported without layout or footprint modifications.

Compliance and Availability: The DB207L-BP carries Active product status, ensuring ongoing availability and supply chain continuity. Both parts maintain REACH Unaffected compliance status. The DB207L-BP is currently in stock (987 Pcs New Original), supporting immediate procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can the DB207L-BP replace the DB204L-BP in existing designs?

A: Yes. The DB207L-BP is electrically and mechanically equivalent to the DB204L-BP. All critical parameters including current rating (2 A), forward voltage (1.1 V @ 2 A), operating temperature range (-55°C to 150°C), and package configuration (4-EDIP, DBL-1) are identical. The higher voltage rating (1 kV) does not affect performance in 400 V applications.

Q: What is the difference between the DB204L-BP and DB207L-BP?

A: The primary difference is the peak reverse voltage rating. The DB204L-BP is rated for 400 V, while the DB207L-BP is rated for 1 kV. All other electrical and mechanical specifications are identical. The DB207L-BP is the active product, while the DB204L-BP is obsolete.

Q: Are there any package or footprint differences between these parts?

A: No. Both parts use the 4-EDIP package with identical dimensions (0.321", 8.15mm) and the DBL-1 supplier device package. Through-hole mounting configuration is identical. No PCB layout or design modifications are required for substitution.

Q: Why would I use the DB207L-BP if my circuit only requires 400 V?

A: The DB207L-BP provides additional voltage margin and safety headroom in your circuit design. Higher voltage-rated components do not degrade performance at lower operating voltages. The DB207L-BP is the active product with guaranteed long-term availability, whereas the DB204L-BP is obsolete.

Q: What compliance certifications apply to both parts?

A: Both the DB204L-BP and DB207L-BP carry REACH Unaffected status, indicating compliance with EU chemical substance regulations. Both parts are classified under ECCN EAR99 and HTSUS 8541.10.0080.

Q: Can I use the DB207L-BP in reverse leakage-sensitive applications?

A: Yes. The reverse leakage current is specified at the respective voltage ratings: 10 µA @ 400 V for the DB204L-BP and 10 µA @ 1000 V for the DB207L-BP. At 400 V operation, the DB207L-BP will exhibit leakage characteristics suitable for the same applications as the original part.
