DB202L-BP Bridge Rectifier Single Phase Standard 100 V Through Hole

Part Overview

The DB202L-BP is a single-phase bridge rectifier manufactured by Micro Commercial Co, designed for interface applications requiring 100 V peak reverse voltage with 2 A average rectified current. This component features a through-hole 4-EDIP package (DBL-1) and operates across a temperature range of -55°C to 150°C. The DB202L-BP is classified as obsolete, making identification of functionally compatible alternatives necessary for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DB202L-BP is determined by 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)
• Current - Reverse Leakage: 10 µA (must match or be lower)
• Operating Temperature Range: -55°C ~ 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 DB202L-BP operates at 100 V peak reverse voltage. Substitute parts may operate at higher voltage ratings while maintaining all other electrical and mechanical parameters. A higher voltage rating does not disqualify a part from substitution, as it provides equal or greater circuit protection capability.

The DB207L-BP meets all substitution criteria while offering enhanced voltage performance at 1 kV peak reverse voltage, maintaining identical current ratings, forward voltage characteristics, and physical packaging.

Parameter Comparison

Engineering Selection Recommendations

The DB202L-BP is classified as obsolete, requiring substitution for new procurement and long-term design support. The DB207L-BP is the manufacturer-recommended substitute and is currently in active production status.

Substitution Basis:

The DB207L-BP maintains electrical equivalence across all critical parameters: identical 2 A average rectified current, 1.1 V forward voltage at 2 A, and -55°C to 150°C operating temperature range. Mechanical compatibility is preserved through identical through-hole mounting, 4-EDIP package configuration, and DBL-1 supplier device package designation.

The primary difference is the peak reverse voltage rating: DB207L-BP operates at 1 kV compared to the DB202L-BP at 100 V. This represents an enhancement in voltage capability that provides superior circuit protection without introducing any electrical or mechanical incompatibility.

Both components maintain identical REACH compliance status (REACH Unaffected) and export classification (EAR99), with matching HTSUS commodity codes (8541.10.0080).

Frequently Asked Questions (FAQ)

Q: Can the DB207L-BP directly replace the DB202L-BP in existing circuit designs?

A: Yes. The DB207L-BP is electrically and mechanically compatible with the DB202L-BP. Both components share identical current ratings (2 A), forward voltage characteristics (1.1 V @ 2 A), operating temperature range (-55°C to 150°C), and physical packaging (4-EDIP through-hole DBL-1). The higher voltage rating of the DB207L-BP (1 kV vs. 100 V) does not create incompatibility; it provides enhanced overvoltage protection.

Q: What is the significance of the voltage rating difference between these parts?

A: The DB202L-BP is rated for 100 V peak reverse voltage, while the DB207L-BP is rated for 1 kV. In substitution, a higher voltage rating is acceptable because it maintains or exceeds the circuit's voltage handling capability. The DB207L-BP will function identically in applications designed for 100 V operation while providing additional safety margin against transient overvoltages.

Q: Are the physical packages identical?

A: Yes. Both the DB202L-BP and DB207L-BP use the 4-EDIP package with dimensions of 0.321" (8.15mm). Both are supplied in the DBL-1 package configuration and mount through-hole, ensuring direct PCB compatibility without layout modifications.

Q: What is the product status difference, and why does it matter?

A: The DB202L-BP is obsolete, meaning it is no longer manufactured and existing inventory is limited. The DB207L-BP is active production, ensuring long-term availability for new designs and ongoing procurement. For new designs or component replenishment, the DB207L-BP is the appropriate selection.

Q: Are compliance certifications identical?

A: Yes. Both components maintain REACH Unaffected status, EAR99 export classification, and identical HTSUS commodity code 8541.10.0080. No compliance differences exist between the two parts.

Q: What are the key electrical parameters that must match for substitution?

A: For bridge rectifier substitution, the following parameters must be equivalent or superior: diode type (single phase), technology (standard), average rectified current (2 A), forward voltage (1.1 V @ 2 A), reverse leakage current (10 µA), and operating temperature range (-55°C to 150°C). Peak reverse voltage may be higher in the substitute part.
