D53TP25D Solid State Relay - Equivalent & Substitute Parts

Part Overview

The D53TP25D is a solid state relay (SSR) manufactured by Sensata Technologies, configured as a 3PST-NO (3 Form A) module with 25A load capacity and AC zero-cross output control. This component is classified as Active product status and is RoHS Compliant. Substitute parts are identified when equivalent electrical specifications and mechanical mounting requirements align with the main part's operational parameters, enabling direct replacement in applications where component availability or supply chain considerations necessitate alternative sourcing.

Key Parameters

Parameter	Value
Circuit Configuration	3PST-NO (3 Form A)
Output Type	AC, Zero Cross
Load Current	25 A
Input Voltage Range	4 ~ 32 VDC
Load Voltage Range	48 V ~ 530 V
Termination Style	Screw Terminal
Package Type	Module
Mounting Type	Chassis Mount

Substitute Part Grouping Explanation

Substitution eligibility for the D53TP25D is determined by the following critical parameters:

Circuit configuration must be 3PST-NO (3 Form A)
Output type must be AC with zero-cross functionality
Load current rating must be 25 A
Input voltage range must accommodate 4 ~ 32 VDC
Load voltage range must support minimum 48 V operation
Termination must be screw terminal
Package type must be module format

Three substitute parts meet these criteria with the following considerations:

GN325DSZ (Sensata-Crydom): Matches all electrical specifications. Differs in mounting type (DIN Rail vs. Chassis Mount) and packaging format (Bulk vs. Tube).

ASR-SQF480D25ZW (Altran Magnetics): Matches all electrical specifications. Load voltage range begins at 24 V (lower minimum than main part). Maintains Chassis Mount configuration and Module package type.

GN325DSZH (Crouzet): Matches all electrical specifications. Load voltage range is 24 V ~ 510 V (lower minimum, slightly lower maximum than main part). Supports both Chassis Mount and Panel Mount configurations.

Engineering Selection Recommendations

All four parts maintain Active product status, ensuring continued manufacturer support and availability. The D53TP25D, GN325DSZ, ASR-SQF480D25ZW, and GN325DSZH are RoHS3 compliant, meeting current environmental and regulatory requirements.

GN325DSZ is suitable for applications where DIN Rail mounting is acceptable and bulk packaging is preferred. This part shares identical electrical specifications with the main part.

ASR-SQF480D25ZW is suitable for applications operating at load voltages below 48 V, as it supports 24 V minimum operation. It maintains Chassis Mount configuration and Module packaging consistent with the main part. REACH Unaffected status may be advantageous in certain supply chain contexts.

GN325DSZH is suitable for applications requiring flexible mounting options (Chassis Mount or Panel Mount). It supports load voltages as low as 24 V and operates to 510 V maximum. REACH Unaffected status and MSL 1 (Unlimited) rating provide additional flexibility for storage and handling.

Frequently Asked Questions (FAQ)

Q: Can GN325DSZ replace D53TP25D in a chassis-mounted application?

A: GN325DSZ has DIN Rail mounting type versus Chassis Mount on the main part. Electrical specifications are identical, but mechanical integration differs. Application feasibility depends on available mounting infrastructure.

Q: What is the significance of the load voltage range difference in ASR-SQF480D25ZW?

A: ASR-SQF480D25ZW operates at 24 V minimum load voltage compared to 48 V minimum on D53TP25D. This part is suitable for applications requiring lower voltage operation. Both parts support the full 530 V upper range.

Q: Does GN325DSZH have any operational limitations compared to D53TP25D?

A: GN325DSZH maximum load voltage is 510 V versus 530 V on the main part. For applications operating above 510 V, this part is not suitable. All other electrical parameters are equivalent.

Q: What packaging differences exist among these parts?

A: D53TP25D is supplied in Tube packaging. GN325DSZ is supplied in Bulk format. ASR-SQF480D25ZW and GN325DSZH are supplied in Box packaging. Packaging affects order quantities and storage considerations but does not impact electrical performance.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. D53TP25D is RoHS Compliant, and all three substitute parts are ROHS3 Compliant, meeting current environmental standards.

Q: What is the REACH compliance status difference?

A: D53TP25D and GN325DSZ are REACH Affected. ASR-SQF480D25ZW and GN325DSZH are REACH Unaffected. REACH status affects regulatory documentation requirements in certain jurisdictions.
