CD4850D2VR Equivalent & Substitute Parts

Part Overview

The CD4850D2VR is a solid-state relay (SSR) manufactured by Sensata-Crydom, configured as a dual SPST-NO (1 Form A) module in Hockey Puck packaging. This component is rated for 50A load current with input voltage range of 4–15VDC and output voltage range of 48–660VAC. The part is currently classified as obsolete, making identification of active equivalent and substitute parts essential for ongoing system maintenance and new design implementations.

Substitute Part Grouping Explanation

Substitution eligibility for the CD4850D2VR is determined by the following critical parameters:

Circuit Configuration: SPST-NO (1 Form A) x 2 (dual channel requirement)
Output Type: AC operation
Load Current Rating: 50 A minimum
Voltage - Load Range: 48 V ~ 660 V compatibility
Mounting Type: Chassis Mount
Termination Style: Screw Terminal
Package / Case: Hockey Puck form factor

Substitute parts must maintain all of these specifications. Variations in input voltage range (4–15VDC vs. 4–32VDC) are permissible when the substitute part meets or exceeds the original input voltage specification. Product status transitions from obsolete to active are acceptable for direct substitution purposes.

Engineering Selection Recommendations

CC4850D2VR is the direct equivalent substitute. This part is manufactured by Sensata Technologies (parent company of Sensata-Crydom) and maintains identical electrical and mechanical specifications to the CD4850D2VR. The transition from obsolete to active product status makes this the primary replacement option. RoHS compliance certification is included.

CD4850W2VR is a compatible substitute with extended input voltage range (4–32VDC vs. 4–15VDC). This part is manufactured by Sensata-Crydom and maintains all other critical parameters. The expanded input voltage specification provides additional operational flexibility. RoHS compliance certification is included.

CD4850D3VRH is a manufacturer-recommended substitute designated by Sensata-Crydom. This part maintains identical specifications to the CD4850D2VR with active product status and RoHS compliance certification.

All three substitute parts are suitable for direct replacement in applications currently using the CD4850D2VR, provided that the input voltage requirements of the application do not exceed the specified ranges.

Frequently Asked Questions (FAQ)

Q: Can CC4850D2VR replace CD4850D2VR in existing designs?

A: Yes. CC4850D2VR is a direct equivalent with identical electrical and mechanical specifications. The manufacturer transition from Sensata-Crydom to Sensata Technologies does not affect functional compatibility.

Q: What is the difference between CD4850W2VR and CD4850D2VR?

A: CD4850W2VR has an extended input voltage range of 4–32VDC compared to the 4–15VDC range of CD4850D2VR. All other parameters remain identical. CD4850W2VR is suitable for applications requiring higher input voltage tolerance.

Q: Is CD4850D3VRH a direct replacement?

A: Yes. CD4850D3VRH is the manufacturer-recommended substitute and maintains all critical specifications of the CD4850D2VR.

Q: Are all substitute parts available in the same Hockey Puck package?

A: Yes. All substitute parts use the Hockey Puck form factor with Chassis Mount configuration and Screw Terminal termination.

Q: Do the substitute parts have RoHS compliance?

A: Yes. CC4850D2VR, CD4850W2VR, and CD4850D3VRH are all RoHS Compliant. The original CD4850D2VR RoHS status was not specified.

Q: Can these parts be used interchangeably in the same circuit?

A: Yes, provided the application input voltage does not exceed the specified range of the selected substitute part. For applications with input voltages above 15VDC, CD4850W2VR is the appropriate selection.
