D53TP50C-10 Equivalent & Substitute Parts

Part Overview

The D53TP50C-10 is a solid state relay (SSR) module manufactured by Sensata-Crydom, configured as a 3PST-NO (3 Form A) relay with 50A load current capacity and 48-530V AC output voltage range. This active product is designed for chassis mount applications with screw terminal connections and operates on 4-32VDC input control voltage. The module is ROHS3 compliant and REACH affected, making it suitable for regulated industrial and commercial applications.

Equivalent and substitute parts are identified when product availability is limited, supply chain disruptions occur, or when design flexibility permits component interchange within specified electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitute parts for the D53TP50C-10 are qualified based on the following electrical and mechanical compatibility criteria:

Critical Parameters for Substitution:

• Circuit configuration: 3PST-NO (3 Form A) topology
• Output type: AC switching capability
• Input voltage range: 4 ~ 32VDC control voltage
• Load voltage range: Minimum 24V to maximum 530V AC
• Load current capacity: Minimum 50A or greater
• Mounting type: Chassis Mount
• Termination style: Screw Terminal
• Package type: Module form factor

The ASR-SQF480D60RW qualifies as a substitute based on matching all critical parameters. The substitute part maintains identical circuit topology, input/output voltage compatibility, and mechanical interface specifications. The higher load current rating (60A vs. 50A) and lower minimum load voltage (24V vs. 48V) provide enhanced operational flexibility within the same form factor and mounting configuration.

Parameter Comparison

Engineering Selection Recommendations

Both the D53TP50C-10 and ASR-SQF480D60RW are active products with ROHS3 compliance, ensuring regulatory alignment for current manufacturing and deployment. The D53TP50C-10 remains the primary specification when original manufacturer continuity is required. The ASR-SQF480D60RW serves as a qualified substitute when D53TP50C-10 availability is constrained, provided that the design application accommodates the lower minimum load voltage threshold (24V vs. 48V) and the higher current rating does not introduce thermal or mechanical constraints in the target circuit.

Selection between these parts should be based on supply chain availability, lead time requirements, and design margin considerations rather than functional capability differences.

Frequently Asked Questions (FAQ)

Q: Can the ASR-SQF480D60RW directly replace the D53TP50C-10 in existing designs?

A: Yes, provided the application load voltage does not fall below 24V AC. The D53TP50C-10 specifies a minimum load voltage of 48V, while the ASR-SQF480D60RW operates at 24V minimum. If the design operates exclusively at or above 48V, both parts are functionally equivalent. The higher current rating of the substitute part (60A vs. 50A) does not create compatibility issues in circuits designed for 50A operation.

Q: What are the key electrical differences between these parts?

A: The primary electrical differences are the minimum load voltage specification (48V vs. 24V) and maximum load current rating (50A vs. 60A). Both parts share identical input voltage range (4-32VDC), output type (AC), circuit topology (3PST-NO), and maximum load voltage (530V). These differences represent design margins rather than functional incompatibilities.

Q: Are both parts suitable for the same mounting and termination applications?

A: Yes. Both parts are chassis mount modules with screw terminal connections, ensuring mechanical and electrical interface compatibility in the same circuit board or panel layout.

Q: What compliance certifications apply to both parts?

A: Both the D53TP50C-10 and ASR-SQF480D60RW are ROHS3 compliant. The D53TP50C-10 is REACH affected, while the ASR-SQF480D60RW is REACH unaffected. Regulatory requirements for the target application should guide part selection when REACH compliance is a design constraint.

Q: How should packaging differences be considered?

A: The D53TP50C-10 is supplied in tube packaging, while the ASR-SQF480D60RW is supplied in box packaging. This difference affects receiving, storage, and handling procedures but does not impact electrical or mechanical performance.
