D53TP50D Equivalent & Substitute Parts

Part Overview

The D53TP50D is a solid-state relay (SSR) manufactured by Sensata-Crydom, configured as a 3PST-NO (3 Form A) module with 50A load current capacity and 48-530V load voltage range. This chassis-mount component operates with 4-32VDC input control voltage and features zero-cross AC output switching. The part maintains active product status and is ROHS3 compliant with REACH affected classification.

Equivalent and substitute parts are identified when they maintain functional compatibility across critical electrical parameters including circuit configuration, load current rating, input voltage range, and output voltage operating window, while accommodating variations in mounting type and packaging format.

Substitute Part Grouping Explanation

Substitute parts for the D53TP50D are qualified based on the following critical parameters:

Mandatory Compatibility Criteria:

Circuit configuration must be 3PST-NO (3 Form A)
Output type must be AC with zero-cross switching
Input voltage range must encompass 4-32VDC
Load voltage range must overlap with 48-530V minimum
Termination style must be screw terminal
Product status must be active

Allowable Variations:

Mounting type may differ (DIN Rail, Chassis Mount, or Panel Mount)
Packaging format may vary (Tube, Bulk, Box, Module)
Load current may equal or exceed 50A
Load voltage minimum may be lower than 48V
Manufacturer may differ

Three substitute parts meet these criteria with documented electrical and mechanical compatibility.

Engineering Selection Recommendations

GN350DSZ (Sensata-Crydom): This substitute maintains identical electrical specifications to the D53TP50D with matching 50A load current and 48-530V load voltage range. The primary difference is DIN Rail mounting versus chassis mount. Both parts share ROHS3 compliance and REACH affected status. Selection is appropriate when DIN Rail mounting accommodates the application requirement.

GN350DSZH (Crouzet): This substitute provides 50A load current matching the D53TP50D with a slightly reduced load voltage minimum of 24V versus 48V. The upper load voltage limit of 510V remains within acceptable operating parameters for most applications. Mounting flexibility includes chassis mount or panel mount options. REACH unaffected status may be advantageous in certain regulatory environments compared to the REACH affected D53TP50D.

ASR-SQF480D60ZW (Altran Magnetics): This substitute provides 60A load current, exceeding the D53TP50D specification by 10A, with load voltage range of 24-530V. The lower minimum load voltage of 24V expands application flexibility. Chassis mount configuration matches the D53TP50D. REACH unaffected status is available. Selection is appropriate when higher current capacity is required or beneficial for thermal margin.

Frequently Asked Questions (FAQ)

Q: Can GN350DSZ replace D53TP50D in a chassis-mount application? A: GN350DSZ is DIN Rail mounted, not chassis mount. While electrical specifications are identical, the mounting type differs. Application feasibility depends on whether the system can accommodate DIN Rail mounting or if an adapter solution is available.

Q: What is the significance of the load voltage range difference in GN350DSZH? A: GN350DSZH operates from 24-510V load voltage versus D53TP50D at 48-530V. The lower 24V minimum expands compatibility with lower-voltage AC loads. The 510V maximum remains suitable for standard industrial AC applications up to 480V nominal systems.

Q: Why does ASR-SQF480D60ZW have 60A rating instead of 50A? A: The 60A rating provides additional current capacity. This substitute is suitable for D53TP50D applications and offers thermal margin for systems operating near the 50A limit. No derating is required when substituting into 50A-rated circuits.

Q: Are all substitutes ROHS3 compliant? A: Yes. D53TP50D, GN350DSZ, GN350DSZH, and ASR-SQF480D60ZW are all ROHS3 compliant, meeting hazardous substance restrictions for electronic components.

Q: What is the difference between REACH Affected and REACH Unaffected status? A: REACH Affected parts (D53TP50D, GN350DSZ) are subject to REACH chemical substance regulations. REACH Unaffected parts (GN350DSZH, ASR-SQF480D60ZW) are not subject to these restrictions. Selection depends on regulatory requirements in the end-use market.

Q: Can these substitutes be used interchangeably in the same circuit? A: Electrical interchangeability is confirmed for all three substitutes based on circuit configuration, input/output voltage ranges, and termination style. Physical interchangeability depends on mounting type compatibility within the specific application enclosure or panel.
