D53RV50C Equivalent & Substitute Parts

Part Overview

The D53RV50C is a solid-state relay (SSR) module manufactured by Sensata-Crydom, configured as a 3PST-NO (3 Form A) relay with 50A load current capacity and 48–530V AC output voltage range. This chassis-mount module operates with 4–32VDC input control voltage and features screw terminal connections. The product is classified as obsolete, necessitating identification of active equivalent alternatives that maintain functional compatibility for existing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the D53RV50C is determined by the following critical parameters:

• Circuit Configuration: The main part operates as 3PST-NO (3 Form A). Substitute parts must maintain this configuration to preserve the three independent switching channels.
• Load Current: Fixed at 50 A. Substitutes must support this current rating.
• Output Voltage Range: 48–530 V AC. Substitutes must accommodate this range or a compatible superset.
• Input Control Voltage: 4–32 VDC. Substitutes must operate within or overlap this range.
• Termination and Mounting: Screw terminal connections and chassis mount configuration define the physical interface requirements.
• Output Type: AC output with standard switching (no zero-cross requirement for the main part).

Two substitute parts are identified:

1. GN050DSR (Sensata-Crydom): SPST-NO configuration—single switching channel instead of three. Functionally incompatible for applications requiring three independent relay channels.
2. GN050DSRL (Crouzet): 3PST-NO configuration—maintains three independent channels. Input voltage range 12–30 VDC (subset of original), load voltage 24–510 V (subset of original), and includes zero-cross switching capability.

Parameter Comparison

Engineering Selection Recommendations

GN050DSRL is the functionally equivalent substitute for D53RV50C applications. Both parts maintain 3PST-NO circuit configuration, 50 A load current, screw terminal termination, and module packaging. The GN050DSRL operates with input voltage 12–30 VDC (within the original 4–32 VDC range for typical 24 VDC control systems) and load voltage 24–510 V (covering the majority of the original 48–530 V range). The GN050DSRL adds zero-cross switching capability and supports both chassis and panel mounting, providing design flexibility. Both parts are RoHS compliant; GN050DSRL carries ROHS3 certification and REACH unaffected status, meeting current regulatory requirements.

GN050DSR is not recommended as a direct substitute. Although manufactured by Sensata-Crydom with identical input/output voltage ranges and 50 A current rating, the SPST-NO (single channel) configuration is functionally incompatible with applications requiring three independent relay channels provided by the 3PST-NO main part.

Frequently Asked Questions (FAQ)

Q: Can GN050DSR replace D53RV50C? A: No. GN050DSR is a SPST-NO (single-channel) relay, while D53RV50C is 3PST-NO (three-channel). Applications requiring three independent switching channels cannot use GN050DSR.

Q: What are the voltage compatibility considerations for GN050DSRL? A: GN050DSRL operates with input voltage 12–30 VDC, which covers standard 24 VDC control systems but does not extend to the lower 4 VDC minimum of the original part. Load voltage range is 24–510 V, which covers most industrial AC applications but does not extend to the original 48 V minimum. Verify that your application operates within these ranges before substitution.

Q: Does GN050DSRL require circuit modifications? A: GN050DSRL maintains identical circuit configuration (3PST-NO), termination style (screw terminal), and mounting interface (chassis mount) as D53RV50C. No circuit modifications are required for pin-compatible replacement. The addition of zero-cross switching in GN050DSRL may improve performance in certain AC load applications but does not necessitate design changes.

Q: Are there packaging differences between D53RV50C and GN050DSRL? A: D53RV50C is supplied in tube packaging; GN050DSRL is supplied in box packaging. Both are module-format solid-state relays with identical electrical interfaces and mounting footprints.

Q: What compliance certifications apply to GN050DSRL? A: GN050DSRL is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for industrial component applications.
