C53TP50C Equivalent & Substitute Parts

Part Overview

The C53TP50C is a solid-state relay (SSR) manufactured by Sensata-Crydom, classified as a 3PST-NO (3 Form A) module designed for industrial switching applications. This component operates with an input voltage range of 180–280VAC and supports load voltages from 48V to 530V at a maximum load current of 50A. The device features zero-cross switching for AC output and utilizes screw terminal connections for permanent installation in chassis-mounted configurations. The product maintains Active status and is RoHS Compliant, making it suitable for modern industrial and commercial equipment requiring reliable solid-state switching without mechanical contacts.

Equivalent and substitute parts are identified when they maintain functional compatibility across critical electrical parameters (input voltage, load voltage range, load current capacity, and circuit configuration) while meeting or exceeding the original specification's performance and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C53TP50C is determined by strict alignment with the following critical parameters:

• Circuit Configuration: Must be 3PST-NO (3 Form A) to maintain identical switching topology
• Load Current Capacity: Must support minimum 50A continuous operation
• Load Voltage Range: Must encompass or exceed the 48–530V specification window
• Input Voltage Compatibility: Must accept the control signal voltage range (180–280VAC or compatible DC/AC input)
• Output Type: Must feature AC switching with zero-cross capability to prevent electromagnetic interference and ensure synchronized switching
• Termination and Mounting: Must utilize screw terminal connections and support chassis-mount installation
• Compliance Status: Must maintain active product status and RoHS compliance for regulatory alignment

The GN350ASZH (Crouzet) meets these substitution criteria through equivalent circuit topology, matching load current rating, compatible voltage ranges, and superior compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The GN350ASZH qualifies as a direct substitute for the C53TP50C based on functional equivalence across all critical switching parameters. Both components maintain Active product status, ensuring long-term availability and supply chain stability. The GN350ASZH carries ROHS3 Compliant certification, which exceeds the RoHS Compliant status of the C53TP50C, providing enhanced environmental and regulatory alignment.

The GN350ASZH offers expanded mounting flexibility through dual Chassis Mount or Panel Mount capability, providing installation adaptability beyond the C53TP50C's chassis-mount-only configuration. The input voltage range of the GN350ASZH (24–255VAC/DC) is narrower than the C53TP50C (180–280VAC), requiring verification that the control signal voltage in the target application falls within the 24–255VAC/DC window. The load voltage range of the GN350ASZH (24–510V) is marginally lower than the C53TP50C (48–530V), with the lower bound at 24V versus 48V and the upper bound at 510V versus 530V. Applications requiring operation at the extreme upper voltage limit (530V) or lower input control voltages below 24VAC/DC must retain the C53TP50C.

Both components share identical load current capacity (50A), circuit topology (3PST-NO), output switching type (AC, Zero Cross), and termination methodology (Screw Terminal), confirming functional interchangeability within the specified parameter boundaries.

Frequently Asked Questions (FAQ)

Q: What determines whether the GN350ASZH can replace the C53TP50C?

A: Substitution is valid when the application's control signal voltage falls within 24–255VAC/DC and the load voltage requirement does not exceed 510V. The circuit topology, load current capacity, and switching characteristics are identical, ensuring functional compatibility.

Q: Can the GN350ASZH be used in applications requiring 530V load voltage?

A: No. The GN350ASZH supports load voltages up to 510V, while the C53TP50C extends to 530V. Applications requiring operation at 530V must use the C53TP50C.

Q: What is the input voltage difference between these two relays?

A: The C53TP50C accepts 180–280VAC control input, while the GN350ASZH accepts 24–255VAC/DC. If the control signal is below 24VAC or above 255VAC/DC, the C53TP50C must be used.

Q: Are the mounting options interchangeable?

A: The C53TP50C is Chassis Mount only. The GN350ASZH supports both Chassis Mount and Panel Mount configurations, providing greater installation flexibility. Both can be used in chassis-mount applications.

Q: Do both relays have the same compliance certifications?

A: Both are RoHS compliant. The GN350ASZH carries ROHS3 Compliant certification, which represents a more current compliance standard than the C53TP50C's RoHS Compliant status. Both are EAR99 classified and suitable for regulated environments.

Q: What is the load current capacity for both relays?

A: Both the C53TP50C and GN350ASZH support 50A continuous load current with identical 3PST-NO circuit topology and zero-cross AC switching.
