A53TP25D Equivalent & Substitute Parts

Part Overview

The A53TP25D is a solid-state relay (SSR) manufactured by Sensata-Crydom, configured as a 3PST-NO (3 Form A) module with 25A load capacity and 48-530V output voltage range. This component is classified as Active product status and is RoHS compliant. Finding equivalent or substitute parts may be necessary due to inventory constraints, lead time requirements, or specific mounting configuration needs while maintaining identical electrical performance specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the A53TP25D is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: Must be 3PST-NO (3 Form A)
• Load Current Rating: Must be 25 A
• Output Voltage Range: Must be 48 V ~ 530 V
• Output Type: Must be AC with Zero Cross functionality
• Termination Style: Must be Screw Terminal
• Manufacturer: Sensata-Crydom

The GN325ASZ meets all electrical substitution criteria. The primary difference is the mounting type (DIN Rail vs. Chassis Mount), which represents a mechanical variation that does not affect electrical compatibility when integrated into systems designed to accommodate either mounting configuration.

Parameter Comparison

Engineering Selection Recommendations

Both the A53TP25D and GN325ASZ are Active product status components manufactured by Sensata-Crydom with RoHS compliance certification. Selection between these parts is based on mechanical integration requirements:

• A53TP25D: Select when Chassis Mount configuration is required for direct panel or enclosure mounting applications.
• GN325ASZ: Select when DIN Rail mounting is required for standard industrial control panel integration.

The GN325ASZ has a narrower input voltage range (180 ~ 280 VAC vs. 90 ~ 280 VAC). Verify that the control signal voltage in your application falls within the 180 ~ 280 VAC specification before selecting GN325ASZ as a substitute.

Frequently Asked Questions (FAQ)

Q: Can GN325ASZ replace A53TP25D in all applications?

A: GN325ASZ is electrically equivalent for load switching (25A, 48-530V AC output, 3PST-NO configuration). The primary consideration is mounting type: GN325ASZ requires DIN Rail mounting while A53TP25D requires Chassis Mount. Additionally, GN325ASZ input voltage range is 180-280 VAC; verify your control signal voltage is within this range.

Q: What is the difference between Chassis Mount and DIN Rail mounting?

A: Chassis Mount (A53TP25D) is designed for direct attachment to enclosure panels or frames using mounting hardware. DIN Rail (GN325ASZ) is designed for snap-on installation to standard 35mm DIN rails commonly used in industrial control cabinets. These are mechanical differences that do not affect electrical performance.

Q: Are both parts RoHS compliant?

A: Yes, both A53TP25D and GN325ASZ are RoHS compliant and carry EAR99 ECCN classification.

Q: What does 3PST-NO (3 Form A) mean?

A: 3PST-NO indicates three independent Pole, Single Throw, Normally Open relay contacts. Each contact can independently switch AC loads up to 25A at voltages between 48V and 530V.

Q: Does the input voltage difference affect substitution?

A: The A53TP25D accepts input signals from 90-280 VAC, while GN325ASZ accepts 180-280 VAC. If your control signal is below 180 VAC, GN325ASZ cannot be used. If your control signal is 180 VAC or higher, both parts are compatible.
