RS407L Bridge Rectifier Single Phase 1 kV 4 A Equivalent & Substitute Parts

Part Overview

The RS407L is a single-phase bridge rectifier manufactured by Micro Commercial Co, rated for 1 kV peak reverse voltage and 4 A average rectified current. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. The RS407L features a through-hole RS-4L package configuration and operates across a temperature range of -55°C to 125°C.

Substitute Part Grouping Explanation

Substitute parts for the RS407L are selected based on electrical and mechanical compatibility within the following criteria:

Voltage Rating: Peak reverse voltage must equal or exceed 1 kV
Current Rating: Average rectified current must meet or exceed 4 A
Diode Type: Single-phase bridge rectifier configuration
Technology: Standard bridge rectifier technology
Mounting Type: Through-hole configuration
Package Compatibility: 4-SIP package family (RS-4L or GBU variants)
Forward Voltage Characteristics: Maximum forward voltage at rated current conditions
Reverse Leakage: Maximum reverse leakage current at rated voltage

All substitute parts listed are manufactured by Comchip Technology and feature the GBU package series, which maintains mechanical and electrical compatibility with the RS407L within the specified parameter ranges.

Engineering Selection Recommendations

GBU410-G provides direct electrical equivalence to the RS407L with identical 4 A current rating and 1 kV voltage rating. This part is actively manufactured and ROHS3 compliant, addressing the obsolescence status of the original component. The GBU410-G operates at an extended temperature range (-55°C to 150°C) compared to the RS407L.

GBU610-G and GBU810-G offer higher current ratings (6 A and 8 A respectively) while maintaining the same 1 kV voltage specification. These parts are suitable for applications where the original 4 A rating provides insufficient margin or where design flexibility permits higher current capacity. Both are actively produced and ROHS3 compliant.

GBU2510-G provides the highest current capacity (25 A) within the 1 kV voltage class. This part is appropriate for applications requiring significant current headroom or where future design scaling is anticipated. All substitute parts maintain through-hole mounting compatibility and 4-SIP package family configuration.

Frequently Asked Questions (FAQ)

Q: Can GBU410-G directly replace RS407L in existing designs?

A: Yes. The GBU410-G matches the RS407L in peak reverse voltage (1 kV), average rectified current (4 A), and through-hole mounting configuration. The GBU package maintains mechanical compatibility with RS-4L footprints. The extended operating temperature range (-55°C to 150°C versus -55°C to 125°C) and ROHS3 compliance provide additional design benefits.

Q: What is the difference between GBU410-G, GBU610-G, and GBU810-G?

A: These parts differ only in current rating: GBU410-G is rated for 4 A, GBU610-G for 6 A, and GBU810-G for 8 A. All three maintain identical 1 kV peak reverse voltage, forward voltage characteristics, and operating temperature range. Selection depends on circuit current requirements.

Q: Why is GBU2510-G listed as a substitute if it has 25 A rating?

A: GBU2510-G meets all substitution criteria: 1 kV voltage rating, through-hole mounting, 4-SIP package family, and single-phase bridge rectifier configuration. The higher 25 A current rating does not prevent substitution; it provides additional design margin. Component selection should be based on actual circuit current requirements.

Q: Are there package compatibility concerns between RS-4L and GBU packages?

A: Both RS-4L and GBU packages are 4-SIP through-hole configurations. Mechanical compatibility is maintained for standard PCB layouts. Verify specific footprint dimensions against design documentation if custom or legacy board layouts are in use.

Q: What compliance advantages do the substitute parts offer?

A: All Comchip substitute parts (GBU410-G, GBU610-G, GBU810-G, GBU2510-G) are ROHS3 compliant, whereas the RS407L is RoHS non-compliant. This addresses regulatory requirements for new designs and procurement in regions with RoHS mandates.
