RS407L Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The RS407L is a single-phase bridge rectifier manufactured by Diodes Incorporated, rated for 1 kV peak reverse voltage with 4 A average rectified current. This component is classified as obsolete, making identification of equivalent substitute parts necessary for ongoing design support and procurement continuity. The RS407L features a through-hole RS-4L package configuration and operates across a temperature range of -55°C to 150°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RS407L is determined by the following critical parameters:

• Diode Type & Technology: Single Phase, Standard technology
• Voltage Rating: 1 kV peak reverse voltage (Vrm)
• Current Rating: Minimum 4 A average rectified current (Io)
• Forward Voltage: Maximum 1 V @ specified forward current
• Reverse Leakage: Maximum 10 µA @ 1000 V
• Temperature Range: -55°C to 150°C operating capability
• Mounting Configuration: Through-hole package
• Compliance: ROHS3 compliance required

The GBU410 qualifies as a direct substitute based on matching voltage rating, diode type, technology classification, temperature range, mounting type, and RoHS compliance status. Package compatibility is maintained through equivalent 4-SIP through-hole configuration.

Parameter Comparison

Engineering Selection Recommendations

The GBU410 is listed as an active product with current manufacturing status, providing supply continuity for the obsolete RS407L. Both components maintain ROHS3 compliance and equivalent environmental certifications (EAR99 ECCN classification, 8541.10.0080 HTSUS code). The GBU410 demonstrates superior reverse leakage characteristics at 5 µA compared to the RS407L specification of 10 µA @ 1000 V.

Critical consideration: The GBU410 specifies 166 mA average rectified current, which falls below the RS407L rating of 4 A. This parameter discrepancy requires evaluation against actual circuit current requirements before substitution confirmation.

Frequently Asked Questions (FAQ)

Q: Can the GBU410 directly replace the RS407L in all applications?

A: Voltage rating, diode type, technology, temperature range, and package compatibility are equivalent. However, the GBU410 current rating of 166 mA is significantly lower than the RS407L 4 A specification. Substitution is valid only for applications where actual circuit current demand does not exceed 166 mA.

Q: Are the package configurations physically compatible?

A: Both components use 4-SIP through-hole packages. The RS-4L and GBU packages are mechanically compatible for PCB mounting, though pin spacing and lead geometry should be verified against specific board layout requirements.

Q: What compliance certifications apply to both parts?

A: Both RS407L and GBU410 are ROHS3 compliant. The RS407L carries REACH Affected status, while the GBU410 is REACH Unaffected. Both share identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications.

Q: Why is the GBU410 current rating lower than the RS407L?

A: Current rating differences reflect manufacturer design specifications and testing parameters. The provided data does not include technical justification for this variance.

Q: Should forward voltage differences affect substitution decisions?

A: The GBU410 forward voltage specification (1 V @ 2 A) versus RS407L (1 V @ 3 A) indicates measurement at different current levels. Both maintain the 1 V maximum threshold, though circuit thermal performance may vary slightly depending on actual operating current.
