DB106-BP Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DB106-BP is a single-phase bridge rectifier manufactured by Micro Commercial Co, rated for 800 V peak reverse voltage and 1 A average rectified current. This component is classified as Active and is ROHS3 compliant. Bridge rectifiers in this voltage and current class are widely used in power supply circuits, industrial equipment, and consumer electronics requiring AC-to-DC conversion.

Substitute parts become necessary when the DB106-BP reaches end-of-life status, when inventory constraints occur, or when design requirements allow for alternative electrical or mechanical specifications within acceptable parameters.

Substitute Part Grouping Explanation

Substitution of the DB106-BP is determined by the following critical parameters:

Voltage - Peak Reverse (Max): The substitute must equal or exceed 800 V to maintain voltage margin in the application circuit.
Current - Average Rectified (Io): The substitute must equal or exceed 1 A to handle the specified load current.
Voltage - Forward (Vf): Forward voltage drop must not exceed 1.1 V @ 1 A to maintain circuit efficiency and thermal performance.
Operating Temperature Range: The substitute must support the full -55°C ~ 150°C range or a compatible subset.
Mounting Type: Through-hole mounting is required for PCB compatibility.
Package / Case: Physical dimensions must be compatible with the 4-EDIP form factor.

Substitute parts are grouped into two categories:

Direct Electrical Equivalents: Parts meeting or exceeding all electrical specifications (voltage, current, forward voltage, leakage current) with compatible package dimensions.

Parametric Equivalents: Parts with reduced voltage or current ratings that may be suitable only for applications with lower electrical demands than the DB106-BP specification.

Engineering Selection Recommendations

DF08M meets the full electrical specification of the DB106-BP with 800 V peak reverse voltage and exceeds the current rating at 1.5 A. However, DF08M is classified as Obsolete, which may present long-term supply chain risk. Both parts are ROHS3 compliant and support the required operating temperature range. Package dimensions differ slightly (0.300" vs 0.321"), requiring PCB layout verification.

DF06M provides 600 V peak reverse voltage, which is below the DB106-BP specification of 800 V. This part is also Obsolete. Use only in applications where the actual circuit voltage requirement is 600 V or lower.

DF06 (HY Electronic) is rated for 600 V and 1 A, matching the current specification but falling short on voltage. This part is Active and ROHS3 compliant with matching package dimensions (0.321", 8.15mm). Use only in applications where 600 V rating is sufficient.

DF005M is rated for only 50 V peak reverse voltage and is unsuitable for the DB106-BP application. This part is provided for reference only and does not constitute a valid substitute.

For new designs or long-term production, prioritize Active-status parts. For existing designs requiring exact electrical equivalence, DF08M is the only substitute meeting or exceeding all DB106-BP specifications, with the caveat of Obsolete status and minor package dimension differences.

Frequently Asked Questions (FAQ)

Q: Can DF06M replace DB106-BP in my circuit?

A: DF06M is rated for 600 V peak reverse voltage, while DB106-BP is rated for 800 V. DF06M is suitable only if your circuit operates at 600 V or lower. DF06M is also classified as Obsolete, presenting supply availability concerns.

Q: What is the difference between the 4-EDIP packages listed for DB106-BP and DF08M?

A: DB106-BP uses 4-EDIP (0.321", 8.15mm) while DF08M uses 4-EDIP (0.300", 7.62mm). Although both are 4-EDIP form factors, the physical dimensions differ. PCB footprint and mounting hole spacing must be verified before substitution.

Q: Is DF08M a direct replacement for DB106-BP?

A: DF08M meets the electrical specifications of DB106-BP with equal 800 V rating and higher current capacity (1.5 A vs 1 A). However, DF08M is Obsolete, and package dimensions differ slightly. Electrical compatibility is confirmed; mechanical fit requires verification.

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

A: DF005M is included in the substitute list for reference and completeness. It is not a suitable substitute for DB106-BP applications requiring 800 V operation. DF005M is appropriate only for low-voltage circuits rated 50 V or below.

Q: Can I use DF06 (HY Electronic) instead of DB106-BP?

A: DF06 matches the package dimensions and current rating of DB106-BP but is rated for 600 V instead of 800 V. Use DF06 only if your application operates at 600 V or lower. DF06 is Active status and ROHS3 compliant.

Q: What does "Obsolete" product status mean for DF06M and DF08M?

A: Obsolete status indicates these parts are no longer in active production. While existing inventory may be available, long-term supply cannot be guaranteed. For new designs or production runs, Active-status alternatives are preferred.

Q: Are all substitute parts ROHS3 compliant like DB106-BP?

A: DB106-BP, DF06M, DF08M, and DF06 are all ROHS3 compliant. DF005M compliance status is not specified in the available data.
