D53TP25CH Equivalent & Substitute Parts

Part Overview

The D53TP25CH is a solid-state relay (SSR) manufactured by Sensata-Crydom, classified as a 3PST-NO (3 Form A) module designed for AC load switching applications. This component operates with a 4–32VDC input signal and handles loads up to 25A across a voltage range of 48–530V with zero-cross switching capability. The part is currently in active production status and RoHS compliant.

Equivalent and substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design flexibility permits selection from alternative manufacturers offering compatible electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the D53TP25CH is determined by strict alignment with the following electrical and mechanical parameters:

• Circuit configuration must be 3PST-NO (3 Form A)
• Output type must be AC with zero-cross switching
• Input voltage range must accommodate 4–32VDC
• Load voltage range must support minimum 48V operation
• Load current rating must be 25A
• Termination style must be screw terminal
• Package type must be module format
• Mounting compatibility must include chassis mount capability

The substitute parts listed below meet these criteria and are therefore electrically and mechanically interchangeable with the D53TP25CH in applications where these parameters define the functional requirement.

Engineering Selection Recommendations

All three components listed—D53TP25CH, ASR-SQF480D25ZW-P, and GN325DSZH—maintain active production status and meet current RoHS compliance requirements. The ASR-SQF480D25ZW-P and GN325DSZH both achieve ROHS3 compliance, representing the latest regulatory standard.

Selection between these parts should be based on:

• Load voltage range requirements: The D53TP25CH specifies a minimum load voltage of 48V, while both substitute parts support operation from 24V. Applications requiring operation below 48V load voltage must use ASR-SQF480D25ZW-P or GN325DSZH.
• Maximum load voltage: The D53TP25CH and ASR-SQF480D25ZW-P both support up to 530V, while GN325DSZH supports up to 510V. Applications requiring operation above 510V must use D53TP25CH or ASR-SQF480D25ZW-P.
• Mounting flexibility: GN325DSZH offers both chassis and panel mount options, providing additional design flexibility compared to the chassis-mount-only configuration of the other two parts.
• Packaging format: D53TP25CH is supplied in tube packaging, while ASR-SQF480D25ZW-P and GN325DSZH are supplied in box packaging. Procurement and inventory management practices may influence selection based on packaging preference.

Frequently Asked Questions (FAQ)

Q: Can ASR-SQF480D25ZW-P be used as a direct replacement for D53TP25CH?

A: Yes, ASR-SQF480D25ZW-P is electrically and mechanically compatible with D53TP25CH. Both components share identical circuit configuration (3PST-NO), output type (AC, zero cross), input voltage range (4–32VDC), load current (25A), termination style (screw terminal), and mounting type (chassis mount). The ASR-SQF480D25ZW-P supports a lower minimum load voltage (24V vs. 48V) and identical maximum load voltage (530V), making it suitable for all applications where D53TP25CH is specified.

Q: Can GN325DSZH be used as a direct replacement for D53TP25CH?

A: Yes, GN325DSZH is electrically and mechanically compatible with D53TP25CH. Both components share identical circuit configuration (3PST-NO), output type (AC, zero cross), input voltage range (4–32VDC), load current (25A), and termination style (screw terminal). GN325DSZH supports a lower minimum load voltage (24V vs. 48V) and a maximum load voltage of 510V (compared to 530V). GN325DSZH additionally offers panel mount capability in addition to chassis mount, providing greater mounting flexibility.

Q: What is the significance of the load voltage range difference?

A: The load voltage range defines the AC voltage that the relay can safely switch. D53TP25CH operates from 48–530V, while ASR-SQF480D25ZW-P operates from 24–530V, and GN325DSZH operates from 24–510V. If your application requires switching loads below 48V AC, you must select ASR-SQF480D25ZW-P or GN325DSZH. If your application requires switching loads above 510V AC, you must select D53TP25CH or ASR-SQF480D25ZW-P.

Q: Are there compliance differences between these parts?

A: D53TP25CH is RoHS compliant. ASR-SQF480D25ZW-P and GN325DSZH are both ROHS3 compliant, representing the current regulatory standard. All three parts are classified under ECCN EAR99 for export control purposes. ASR-SQF480D25ZW-P and GN325DSZH both carry REACH Unaffected status.

Q: Does packaging format affect compatibility?

A: Packaging format does not affect electrical or mechanical compatibility. D53TP25CH is supplied in tube packaging, while ASR-SQF480D25ZW-P and GN325DSZH are supplied in box packaging. Selection should be based on procurement requirements, inventory management practices, and supply chain preferences rather than functional performance.

Q: What mounting options are available?

A: D53TP25CH and ASR-SQF480D25ZW-P are configured for chassis mount only. GN325DSZH offers both chassis mount and panel mount options, providing additional design flexibility for applications requiring panel-mounted installation.
