E53TP50C Equivalent & Substitute Parts

Part Overview

The E53TP50C 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 active product operates with an input voltage range of 18–36VAC and supports load voltages from 48V to 530V at a maximum current of 50A. The device features zero-cross switching for AC output and utilizes screw terminal connections for industrial and control applications. Finding equivalent parts may be necessary due to supply constraints, regional availability, or specific application requirements while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the E53TP50C is based on the following critical parameters that must align for functional compatibility:

• Circuit Configuration: Must be 3PST-NO (3 Form A) to maintain the same switching topology
• Load Current Rating: Must be rated for 50A to handle the same load capacity
• Output Type: Must be AC with zero-cross switching for compatible control behavior
• Termination Style: Must use screw terminals for mechanical and electrical compatibility
• Package Type: Must be a module format suitable for the same mounting environment
• Load Voltage Range: Must encompass or exceed the 48V–530V operating range
• Input Voltage Compatibility: Must accept the control signal voltage from the application circuit

The GN350ASZH from Crouzet meets these substitution criteria and is identified as the manufacturer-recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the E53TP50C and GN350ASZH are active products with current manufacturing support. The E53TP50C is RoHS Compliant, while the GN350ASZH meets the more stringent ROHS3 standard and includes REACH Unaffected status, indicating compliance with additional environmental regulations.

The GN350ASZH offers expanded input voltage flexibility (24–255VAC/DC versus 18–36VAC) and supports both chassis and panel mounting configurations, providing greater installation flexibility. The load voltage range of the GN350ASZH (24V–510V) is slightly lower than the E53TP50C (48V–530V) at the upper limit; applications requiring operation above 510V must use the E53TP50C.

Selection should be based on specific application requirements: use the E53TP50C when the full 48V–530V load voltage range is required, or select the GN350ASZH when the lower load voltage ceiling is acceptable and enhanced regulatory compliance is beneficial.

Frequently Asked Questions (FAQ)

Q: Can the GN350ASZH directly replace the E53TP50C in all applications?

A: The GN350ASZH is functionally equivalent for applications where the load voltage does not exceed 510V. Applications requiring operation at voltages between 510V and 530V must use the E53TP50C.

Q: What are the key differences in input voltage specifications?

A: The E53TP50C accepts 18–36VAC input, while the GN350ASZH accepts 24–255VAC/DC input. The GN350ASZH provides broader input voltage compatibility and supports both AC and DC control signals.

Q: Are both parts suitable for the same mounting configurations?

A: The E53TP50C is specified for chassis mount only. The GN350ASZH supports both chassis mount and panel mount, offering greater installation flexibility.

Q: Do both parts meet current environmental compliance standards?

A: The E53TP50C is RoHS Compliant. The GN350ASZH meets the more recent ROHS3 standard and is REACH Unaffected, indicating compliance with current environmental regulations.

Q: Are the screw terminal connections identical between both parts?

A: Both parts use screw terminal connections for load and control signal connections. Physical terminal spacing and wire gauge ratings should be verified against the respective datasheets for the specific application.

Q: What is the significance of the zero-cross switching feature?

A: Zero-cross switching ensures that the SSR switches AC loads only when the AC voltage waveform crosses zero, reducing electromagnetic interference and extending load life in AC applications.
