DF02M Bridge Rectifier Single Phase 200V 1.5A Equivalent & Substitute Parts

Part Overview

The DF02M is a single-phase bridge rectifier diode manufactured by onsemi, rated for 200V peak reverse voltage and 1.5A average rectified current in a 4-DIP through-hole package. The product is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. Substitute parts must maintain electrical compatibility within the specified voltage and current ratings while accommodating available packaging and manufacturer options.

Substitute Part Grouping Explanation

Substitution eligibility for the DF02M is determined by the following criteria:

Primary Compatibility Parameters:

Diode Type: Single Phase (required match)
Technology: Standard (required match)
Mounting Type: Through Hole (required match)
Voltage - Peak Reverse (Max): 200V minimum (equal or higher acceptable)
Current - Average Rectified (Io): 1.5A minimum (equal or higher acceptable)
Operating Temperature Range: Must encompass -55°C to 150°C
Forward Voltage (Vf): 1.1V @ rated current (electrical compatibility)

Package Considerations: Physical package dimensions vary between manufacturers. The DF02M uses 4-EDIP (0.300", 7.62mm), while some substitutes use 4-EDIP (0.321", 8.15mm) or alternative package designations (DFM, DB-M). PCB layout verification is required when package dimensions differ.

Compliance Parameters:

RoHS3 Compliance required
REACH Status: Unaffected or Affected (both acceptable)

Substitutes are grouped into two categories: direct electrical equivalents (matching 200V/1.5A ratings) and higher-voltage alternatives (600V+ ratings suitable for applications with voltage margin requirements).

Engineering Selection Recommendations

Primary Substitute (Direct Equivalent):

DB153 from SMC Diode Solutions is the primary substitute for DF02M. It matches the critical electrical parameters: 200V peak reverse voltage, 1.5A average rectified current, 1.1V forward voltage, and 5µA reverse leakage at rated voltage. Operating temperature range (-55°C to 150°C) is identical. The part is Active status, ensuring long-term availability. Package dimensions differ slightly (0.321" vs 0.300"), requiring PCB layout verification. RoHS3 compliance is confirmed.

Secondary Substitutes (Higher Voltage Rating):

DF06M (onsemi, 600V/1.5A) and DB105-BP (Micro Commercial Co, 600V/1.0A) provide higher voltage margins for applications requiring overvoltage protection. DF06M maintains the 1.5A current rating and onsemi manufacturer continuity but is classified as Obsolete. DB105-BP is Active status with 1.0A current rating, suitable for applications not requiring the full 1.5A capacity. Both use 4-EDIP packages with dimension variations.

Not Recommended for New Designs:

DB103-BP, DB102-BP, DB104-BP, and DB101-BP are classified as "Not For New Designs" by Micro Commercial Co. While electrically compatible within their respective voltage ratings, these parts should not be selected for new product development due to manufacturer lifecycle status.

Unsuitable Substitutes:

DF005M (50V) and DB101-BP (50V) have insufficient voltage ratings for 200V applications and are unsuitable regardless of current capacity.

Frequently Asked Questions (FAQ)

Q: Can DB153 directly replace DF02M without PCB modifications?

A: DB153 is electrically equivalent to DF02M with matching voltage, current, and temperature specifications. However, package dimensions differ: DF02M uses 4-EDIP (0.300", 7.62mm) while DB153 uses 4-EDIP (0.321", 8.15mm). PCB footprint verification is required. If the PCB is designed for the larger 0.321" pitch, DB153 will fit. If designed for 0.300" pitch, layout modification is necessary.

Q: Why is DF005M listed as a substitute if it only handles 50V?

A: DF005M is not a suitable substitute for DF02M applications. The 50V rating is insufficient for 200V circuit requirements. DF005M appears in the substitute list due to cross-reference data but should not be selected for DF02M replacement.

Q: What is the difference between DB105-BP and DF06M for high-voltage applications?

A: Both provide 600V ratings with through-hole mounting. DF06M maintains 1.5A current capacity (matching DF02M) but is Obsolete. DB105-BP is Active status with 1.0A current capacity. For applications requiring 1.5A at elevated voltage, DF06M is preferred if availability permits. For 1.0A or lower applications, DB105-BP offers long-term supply assurance.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry RoHS3 Compliant certification, matching the DF02M compliance status. REACH status varies (Unaffected or Affected), but both designations are acceptable for component selection.

Q: What is the significance of reverse leakage current differences?

A: DF02M and DB153 specify 5µA reverse leakage at rated voltage. Other substitutes specify 10µA. This difference is within standard rectifier diode tolerances and does not affect circuit functionality in typical applications. Applications with stringent leakage requirements should prioritize parts with 5µA specifications.

Q: Can higher-voltage parts (600V, 800V, 1kV) be used in 200V circuits?

A: Yes. Higher voltage-rated rectifiers can be used in lower-voltage applications. The circuit will operate within the diode's safe operating area. However, higher-voltage parts may have different thermal characteristics and reverse leakage behavior. Selection should be based on application requirements and available inventory.
