D53DP25D Equivalent & Substitute Parts

Part Overview

The D53DP25D is a solid-state relay (SSR) module manufactured by Sensata-Crydom, configured as a 3PST-NO (3 Form A) relay with 25A load capacity and 48-530V output voltage range. This component is classified as obsolete, making identification of equivalent substitute parts essential for ongoing system maintenance and new design implementations. The D53DP25D operates with 4-32VDC input control voltage and features zero-cross AC output switching with screw terminal connections suitable for chassis mount applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the D53DP25D is determined by strict equivalence across the following critical parameters:

• Circuit configuration: 3PST-NO (3 Form A) topology
• Load current rating: 25A minimum
• Output voltage range: 48V to 530V minimum
• Input control voltage: 4-32VDC compatibility
• Output switching type: AC with zero-cross capability
• Termination: Screw terminal connection
• Mounting: Chassis mount form factor

The D53TP25D qualifies as a direct substitute based on identical electrical specifications across all critical parameters. Both parts share the same series designation (53TP), circuit configuration, voltage ratings, current capacity, and termination style. The primary distinction is product status: D53TP25D is active production, whereas D53DP25D is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The D53TP25D is the primary substitute for the obsolete D53DP25D. Both components are manufactured by Sensata Technologies (formerly Sensata-Crydom) and maintain identical electrical and mechanical specifications. The D53TP25D is currently in active production with significantly higher inventory availability (20,299 units versus 915 units for the D53DP25D).

For new designs or system replacements, the D53TP25D is the recommended selection. The substitute part carries RoHS Compliant certification and REACH Affected status, reflecting current regulatory compliance standards. Both parts share identical ECCN (EAR99) and HTSUS (8536.49.0080) classifications.

The D53TP25D is supplied in tube packaging, whereas the D53DP25D packaging specification is not detailed. Both maintain the same screw terminal interface and chassis mount form factor, ensuring mechanical and electrical compatibility in existing applications.

Frequently Asked Questions (FAQ)

Q: Can D53TP25D directly replace D53DP25D in existing applications?

A: Yes. The D53TP25D is electrically and mechanically equivalent to the D53DP25D across all critical parameters: 3PST-NO circuit configuration, 25A load current, 48-530V output voltage range, 4-32VDC input voltage, AC zero-cross switching, screw terminal termination, and chassis mount form factor.

Q: What is the primary reason for substitution?

A: The D53DP25D is classified as obsolete. The D53TP25D is the active production equivalent from the same manufacturer, ensuring long-term component availability and supply chain continuity.

Q: Are there packaging differences between these parts?

A: The D53TP25D is supplied in tube packaging. The D53DP25D packaging specification is not provided in the technical data. Both parts use identical screw terminal connections and module form factor.

Q: Do compliance certifications differ between the parts?

A: The D53TP25D carries RoHS Compliant certification and REACH Affected status. The D53DP25D is listed as REACH Unaffected. Both parts share the same ECCN (EAR99) export classification. For applications requiring specific regulatory compliance, verify that the D53TP25D meets your system requirements.

Q: What is the inventory status for each part?

A: The D53DP25D has 915 units in stock (new original). The D53TP25D has 20,299 units in stock (new original), providing significantly greater availability for immediate procurement.
