Substitute Part Grouping Explanation

Substitution for the RS605 is determined by the following critical parameters:

Voltage Rating: Peak reverse voltage must be 600V or higher
Current Rating: Average rectified current must be 6A or higher
Package Type: 4-SIP through-hole configuration (RS-6 or GBU equivalent)
Diode Type: Single-phase bridge rectifier with standard technology
Mounting: Through-hole only
Compliance: ROHS3 compliant preferred

Substitute parts are grouped into two categories:

Category 1 - Direct Equivalents (600V, 6A): Parts with identical voltage and current ratings in compatible packages.

Category 2 - Higher Current Ratings (600V, 8A-10A): Parts with same or higher voltage rating and increased current capacity, suitable for applications with higher current demands.

Category 3 - Higher Voltage Ratings (800V-1kV, 6A-10A): Parts with elevated voltage ratings for applications requiring additional voltage margin.

Engineering Selection Recommendations

Direct Replacement (Same Voltage and Current)

RS605-BP (Micro Commercial Co) is the primary active substitute. It maintains 600V rating and 6A current capacity in the RS-6 package with active product status. Forward voltage is marginally higher at 1.1V versus 1V, which is acceptable for most applications. Operating temperature range extends to 150°C, providing improved thermal margin.

GBU606 (Good-Ark Semiconductor) and GBU606-G (Comchip Technology) provide electrical equivalence at 600V/6A with active status. These use the GBU package variant instead of RS-6, requiring PCB layout verification for pin compatibility.

Higher Current Capacity (600V, 8A-10A)

GBU806-G (Comchip Technology) at 600V/8A and RS1005-BP (Micro Commercial Co) at 600V/10A are suitable for applications requiring current headroom above the 6A rating. These parts maintain the 600V voltage specification while providing increased current capacity.

Higher Voltage Ratings (800V-1kV)

RS606-BP (800V/6A), RS1006-BP (800V/10A), and RS1007-BP (1kV/10A) are applicable where circuit design requires elevated voltage margins or where the application operates at higher input voltages. These maintain or exceed the 6A current requirement.

Compliance and Status

All recommended substitutes are ROHS3 compliant and carry active product status, ensuring long-term availability and supply chain stability. The RS605 original part is obsolete, making active substitutes necessary for new designs and ongoing production.

Frequently Asked Questions (FAQ)

Q: Can GBU package parts replace RS-6 package parts directly?

A: GBU and RS-6 are different physical packages with different pin configurations. While electrically equivalent, PCB layout and footprint must be verified before substitution. Pin-to-pin compatibility cannot be assumed.

Q: Is RS605-BP a direct pin-for-pin replacement for RS605?

A: RS605-BP maintains the RS-6 package and electrical specifications (600V/6A). Pin configuration is identical, making it a direct PCB replacement. The marginal increase in forward voltage (1.1V vs 1V) is within acceptable tolerance for most applications.

Q: Can I use a higher current-rated part like RS1005-BP (10A) instead of the 6A RS605?

A: Yes. Higher current ratings are backward compatible for applications designed for 6A. The part will operate safely at or below its rated current. No circuit modification is required.

Q: What is the difference between RS1006-BP (800V) and RS605 (600V)?

A: RS1006-BP has a higher peak reverse voltage rating (800V vs 600V). This provides additional voltage margin and is suitable for applications with higher input voltages or where voltage transients are a concern. It is not required for 600V-rated circuits but offers improved safety margin.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, meeting environmental and regulatory requirements equivalent to the original RS605.

Q: What is the operating temperature difference between RS605 and its substitutes?

A: The original RS605 operates from -55°C to 125°C. Most active substitutes extend the upper limit to 150°C, providing improved thermal performance and reliability in high-temperature environments.
