RHRA1560CC Equivalent & Substitute Parts

Part Overview

The RHRA1560CC is a diode array rectifier manufactured by onsemi, configured as a 1 Pair Common Cathode design rated for 600 V DC reverse voltage and 15 A average rectified current per diode. The device is packaged in TO-3P-3 (SC-65-3) through-hole configuration and features fast recovery characteristics with a reverse recovery time of 40 ns.

This part is classified as obsolete. Identifying equivalent and substitute components is necessary to support ongoing system maintenance, repair, and production continuity where original inventory is depleted or unavailable.

Substitute Part Grouping Explanation

Substitution of the RHRA1560CC is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

Diode configuration must be 1 Pair Common Cathode
Voltage - DC Reverse (Vr) rating must be 600 V or greater
Current - Average Rectified (Io) per diode must be 15 A or greater
Speed classification must be Fast Recovery (≤ 500 ns, > 200 mA)
Operating temperature range must encompass the application requirements

Mechanical Compatibility Requirements:

Mounting type must be Through Hole
Package footprint must be compatible with the original circuit board layout or require only standard adapter considerations

The substitute part VS-C5PH3006L-N3 (Vishay) meets all electrical equivalence criteria and maintains through-hole mounting compatibility, though in a different package form factor (TO-247-3 versus TO-3P-3).

Engineering Selection Recommendations

Electrical Suitability: The VS-C5PH3006L-N3 satisfies all core electrical requirements for substitution. Forward voltage drop is lower (1.6 V versus 2.1 V), reverse recovery time is faster (38 ns versus 40 ns), and reverse leakage current is significantly reduced (10 µA versus 100 µA). These characteristics represent performance improvements over the original RHRA1560CC.

Temperature Range Consideration: The substitute part operates over -55°C to 175°C, compared to the original -65°C to 175°C. Applications requiring operation below -55°C junction temperature require verification against actual system thermal requirements.

Package Form Factor: The substitute uses TO-247-3 packaging instead of TO-3P-3. This represents a different physical footprint and mounting configuration. Circuit board layout modifications or mechanical adapter solutions may be required for direct replacement.

Product Status: The VS-C5PH3006L-N3 is classified as Active, ensuring ongoing availability and manufacturing support. The RHRA1560CC is obsolete, making the substitute the appropriate choice for new designs and long-term supply continuity.

Frequently Asked Questions (FAQ)

Q: Can the VS-C5PH3006L-N3 directly replace the RHRA1560CC without circuit board modifications?

A: Electrical substitution is valid. However, the TO-247-3 package has a different physical footprint than TO-3P-3. Direct board-level replacement without mechanical adaptation is not possible. Mounting bracket modifications or PCB redesign may be required.

Q: What is the significance of the lower forward voltage drop in the substitute part?

A: The VS-C5PH3006L-N3 exhibits 1.6 V forward voltage drop compared to 2.1 V in the RHRA1560CC at 15 A. This results in reduced power dissipation and heat generation during operation, improving overall system efficiency.

Q: Does the narrower operating temperature range of the substitute affect compatibility?

A: The substitute operates from -55°C to 175°C versus -65°C to 175°C for the original. If the application requires junction temperatures below -55°C, the substitute is not suitable. Verify actual system thermal operating points before selection.

Q: Are both parts through-hole mounted?

A: Yes. Both RHRA1560CC and VS-C5PH3006L-N3 are through-hole mounted devices. The difference lies in package geometry: TO-3P-3 versus TO-247-3.

Q: What does "1 Pair Common Cathode" configuration mean?

A: This indicates the diode array contains two diodes with a shared cathode terminal. Both the RHRA1560CC and VS-C5PH3006L-N3 use this identical configuration, ensuring functional compatibility at the circuit level.

Q: Is the VS-C5PH3006L-N3 suitable for new design applications?

A: Yes. The substitute is classified as Active product status, indicating current manufacturing and full supplier support. It is appropriate for both replacement and new design applications.
