DB202-BP Bridge Rectifier Single Phase Standard 100V Through Hole Equivalent & Substitute Parts

Part Overview

The DB202-BP is a single-phase bridge rectifier manufactured by Micro Commercial Co, designed for through-hole mounting applications requiring 100V peak reverse voltage rating and 2A average rectified current capacity. This component is classified as obsolete, necessitating identification of functionally compatible alternatives for ongoing design support and procurement continuity. The DB202-BP operates across a temperature range of -55°C to 150°C and is housed in a 4-EDIP (0.321", 8.15mm) package configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DB202-BP is determined by the following critical parameters:

Mechanical Compatibility: The substitute part must utilize identical mounting type (through hole) and package configuration (4-EDIP, 0.321", 8.15mm) to ensure direct board-level compatibility without layout modifications.

Electrical Compatibility: The substitute part must maintain the same diode type (single phase), technology classification (standard), and current rating (2A average rectified current). Forward voltage characteristics must remain consistent at 1.1V maximum at 2A.

Voltage Rating Consideration: While the DB202-BP specifies 100V peak reverse voltage, substitute parts may exceed this rating without creating functional incompatibility, as higher voltage-rated components operate safely in lower-voltage applications.

Temperature Performance: Operating temperature range must encompass or match the -55°C to 150°C specification to ensure thermal performance equivalence.

Regulatory Compliance: REACH status and ECCN classification must align to maintain supply chain and export compliance requirements.

Engineering Selection Recommendations

The DB207-BP serves as a direct functional substitute for the DB202-BP based on the following engineering criteria:

Product Status Alignment: The DB207-BP maintains active product status with confirmed inventory availability (7700 pcs), providing supply chain continuity for designs currently utilizing the obsolete DB202-BP.

Electrical Parameter Equivalence: Both components share identical current ratings (2A), forward voltage characteristics (1.1V @ 2A), and operating temperature ranges (-55°C to 150°C). The DB207-BP's elevated peak reverse voltage rating (1 kV versus 100V) presents no functional limitation in applications designed for 100V operation.

Mechanical Interchangeability: Identical through-hole mounting configuration and 4-EDIP package dimensions (0.321", 8.15mm) enable direct board-level substitution without PCB redesign or layout modification.

Regulatory Compliance Maintenance: Both components maintain identical REACH status (REACH Unaffected) and ECCN classification (EAR99), preserving supply chain and export compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the DB207-BP directly replace the DB202-BP on existing PCBs?

A: Yes. Both components utilize identical through-hole mounting and 4-EDIP package dimensions (0.321", 8.15mm), enabling direct substitution without PCB modification.

Q: Why does the DB207-BP have a higher voltage rating (1 kV vs. 100V)?

A: Higher voltage-rated rectifiers operate safely in lower-voltage applications. The DB207-BP's 1 kV rating does not affect performance in 100V circuits and provides additional design margin.

Q: Are the electrical characteristics identical between DB202-BP and DB207-BP?

A: Current rating (2A), forward voltage (1.1V @ 2A), and operating temperature range (-55°C to 150°C) are identical. Reverse leakage current specifications are equivalent at their respective voltage ratings.

Q: What is the inventory status for the DB207-BP?

A: The DB207-BP is in active production with 7700 pcs available in new original condition, providing reliable long-term supply availability.

Q: Do both parts maintain the same regulatory compliance?

A: Yes. Both DB202-BP and DB207-BP carry identical REACH status (REACH Unaffected) and ECCN classification (EAR99).

Q: Is thermal performance affected by substitution?

A: No. Both components operate across the identical temperature range of -55°C to 150°C (TJ), ensuring equivalent thermal performance.
