DF06M Bridge Rectifier Single Phase 600V 1.5A Equivalent & Substitute Parts

Part Overview

The DF06M is a single-phase bridge rectifier diode manufactured by onsemi, rated for 600 V peak reverse voltage and 1.5 A average rectified current in a 4-DIP through-hole package. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. Substitute parts must maintain electrical compatibility across voltage, current, and thermal specifications while accommodating package variations.

Substitute Part Grouping Explanation

Substitution for the DF06M is determined by the following criteria:

Primary Substitution Criteria:

Voltage - Peak Reverse (Max): Must equal or exceed 600 V
Current - Average Rectified (Io): Must equal or exceed 1.5 A
Diode Type: Single Phase (required)
Mounting Type: Through Hole (required)
Operating Temperature Range: Must encompass -55°C to 150°C

Secondary Compatibility Factors:

Forward voltage characteristics at rated current
Reverse leakage current specifications
Package mechanical compatibility (4-EDIP form factor)
RoHS and REACH compliance status

Parts meeting the primary criteria are electrically compatible as direct substitutes. Package dimensional variations (0.300" vs 0.321" pitch) are acceptable within through-hole PCB design tolerances.

Engineering Selection Recommendations

Direct Equivalent (Preferred): DB155 is the primary substitute for DF06M. It matches the 600 V voltage rating and 1.5 A current rating with identical forward voltage and reverse leakage specifications. The part is active in production status and RoHS3 compliant. Package pitch variation (0.321" vs 0.300") is within standard through-hole PCB design tolerances.

Voltage-Rated Alternatives: DB105-BP and DB106-BP provide active alternatives with 600 V and 800 V ratings respectively. Both are RoHS3 compliant and active in production. Current rating is 1.0 A, which is lower than the DF06M specification. These parts are suitable for applications where 1.5 A current capacity is not required.

Higher Voltage Option: DB107-BP offers 1 kV peak reverse voltage rating with 1.0 A current capacity. This part is appropriate for applications requiring higher voltage margin while maintaining active production status and RoHS3 compliance.

Compliance Considerations: All recommended substitutes maintain RoHS3 compliance. DB155 is REACH Affected; DB105-BP, DB106-BP, and DB107-BP are REACH Unaffected. Selection should account for supply chain compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can DB105-BP directly replace DF06M? DB105-BP is electrically compatible at 600 V and -55°C to 150°C operating range. However, current rating is 1.0 A versus DF06M's 1.5 A. Use DB105-BP only if application current requirements do not exceed 1.0 A.

Q: What is the difference between DB155 and DF06M? DB155 and DF06M are functionally equivalent at 600 V, 1.5 A ratings with identical thermal and electrical characteristics. The primary difference is package pitch: DF06M uses 0.300" spacing while DB155 uses 0.321" spacing. Both are acceptable in standard through-hole PCB designs.

Q: Why is DF06M listed as obsolete? DF06M is classified as obsolete by onsemi. DB155 and DB105-BP are active production parts from alternative manufacturers and are recommended for new designs and ongoing production.

Q: Can I use DB106-BP or DB107-BP as substitutes? DB106-BP (800 V, 1.0 A) and DB107-BP (1 kV, 1.0 A) provide higher voltage ratings than DF06M. They are electrically compatible but have reduced current capacity (1.0 A vs 1.5 A). Use these parts only if application current does not exceed 1.0 A and higher voltage margin is beneficial.

Q: Are all substitute parts RoHS compliant? All listed substitutes are RoHS3 compliant. DB155 is REACH Affected; DB105-BP, DB106-BP, and DB107-BP are REACH Unaffected. Verify REACH status requirements for your supply chain.

Q: What package considerations apply to substitution? DF06M uses 4-EDIP (0.300", 7.62mm) pitch. All substitutes use 4-EDIP (0.321", 8.15mm) pitch. This 0.021" difference is within standard through-hole PCB design tolerances and does not require PCB redesign.
