RG 4C Equivalent & Substitute Parts Reference

Part Overview

The RG 4C, manufactured by Sanken Electric USA Inc., is a general-purpose axial diode specified for 1000 V and 2A through-hole applications. This device falls within the Diodes, Rectifiers category and features fast recovery and high voltage ratings suitable for a variety of rectification tasks. The RG 4C is currently listed as obsolete, making it necessary to identify alternative models for replacement in designs or maintenance scenarios.

Key Parameters

Category	Diodes, Rectifiers	Must match application type
Voltage - DC Reverse (Vr) (Max)	1000 V	Must be equal to or greater
Current - Average Rectified (Io)	2A	Must be equal to or greater
Voltage - Forward (Vf) (Max) @ If	3 V @ 2 A	Should be similar or lower
Speed	Fast Recovery =< 500ns, > 200mA (Io)	Should match or be faster
Reverse Recovery Time (trr)	100 ns	Should match or be faster
Current - Reverse Leakage @ Vr	500 µA @ 1000 V	Should not exceed
Mounting Type	Through Hole	Must match mechanical requirements
Package / Case	Axial	Must match footprint requirements
Operating Temp - Junction	-40°C ~ 150°C	Should meet or exceed range
RoHS Status	RoHS Compliant	Should have equivalent compliance

Substitute Part Grouping Explanation

All substitute parts are within the Diodes, Rectifiers category and selected based on strict adherence to the following parameters: maximum reverse voltage rating, average rectified current rating, maximum forward voltage at stated current, recovery speed/reverse recovery time, reverse leakage current, mounting type, package, operating temperature range, and regulatory compliance (RoHS status). Only parts matching or exceeding these electrical, thermal, and regulatory criteria are considered valid substitutes.

Engineering Selection Recommendations

RG 4C is obsolete and engineering selection must prioritize active status and ongoing availability. All substitute parts listed are RoHS compliant and suitable for applications requiring regulatory compliance. Only substitute models with through-hole axial packages and matching or exceeding the electrical and thermal parameters should be used.

Frequently Asked Questions (FAQ)

Q1: What are the main electrical parameters to verify when substituting RG 4C?
A: The critical parameters are maximum reverse voltage (1000 V), average rectified current (2A), forward voltage at operating current, reverse recovery time, and reverse leakage current.

Q2: Does diode mounting and package type affect compatibility?
A: Yes, only through-hole, axial package substitutes are suitable for direct replacement of RG 4C.

Q3: Are listed substitutes compliant with environmental regulations?
A: All substitute parts provided are RoHS compliant as specified in the input.

Q4: What is the impact of product status on selection?
A: Only active, non-obsolete substitutes should be used to ensure ongoing supply and support in applications.

Q5: Must operating temperature be considered in selection?
A: Substitute diodes must meet or exceed the operating junction temperature range specified for RG 4C.

Q6: Are there differences in recovery speed and leakage among substitutes?
A: Refer to the comparison table for specific reverse recovery time and reverse leakage values to match requirements precisely.
