B53TP50CH Equivalent & Substitute Parts

Part Overview

The B53TP50CH is a solid-state relay (SSR) module manufactured by Sensata-Crydom, classified as a 3PST-NO (3 Form A) configuration. This chassis-mount component is designed for AC load switching applications with a rated load current of 50A and operates across a load voltage range of 48V to 530V. The device features zero-cross switching capability and screw terminal connections, making it suitable for industrial control and power distribution applications. As an active product with RoHS compliance, the B53TP50CH remains in production. Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or when design flexibility permits alternative sourcing from qualified manufacturers offering compatible electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the B53TP50CH is permissible when the following core electrical and mechanical parameters are maintained or exceeded:

• Circuit configuration must remain 3PST-NO (3 Form A) to preserve switching topology
• Load current rating must be 50A or greater
• Load voltage range must encompass or exceed 48V to 530V
• Output type must be AC with zero-cross switching capability
• Termination style must be screw terminal for connection compatibility
• Mounting configuration must support chassis mount installation
• Package type must be module format

The substitute part GN350ASZH from Crouzet meets these criteria with compatible electrical ratings and mechanical form factor, though with different input voltage specifications and expanded mounting flexibility.

Parameter Comparison

Engineering Selection Recommendations

Both the B53TP50CH and GN350ASZH are active products with current manufacturing status and regulatory compliance certifications. The B53TP50CH maintains RoHS compliance, while the GN350ASZH achieves ROHS3 compliance with REACH unaffected status, indicating alignment with current environmental and chemical restriction standards.

Selection between these components should be based on input voltage requirements. The B53TP50CH operates with a fixed input range of 90–140VAC, suitable for standard industrial AC control circuits. The GN350ASZH provides broader input flexibility with 24–255VAC/DC operation, accommodating both AC and DC control signal sources.

Load voltage compatibility requires verification: the B53TP50CH supports 48–530V loads, while the GN350ASZH supports 24–510V loads. Applications requiring operation below 48V or above 510V necessitate the B53TP50CH. The GN350ASZH offers expanded mounting options (chassis or panel mount) compared to the B53TP50CH (chassis mount only).

Frequently Asked Questions (FAQ)

Q: Can the GN350ASZH replace the B53TP50CH in all applications?

A: Substitution is valid when the application input voltage falls within 24–255VAC/DC and load voltage remains between 24–510V. Applications requiring input voltages below 24VAC or above 255VAC/DC, or loads above 510V, require the B53TP50CH.

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

A: Both components use screw terminal termination style. Physical terminal pitch and wire gauge compatibility should be verified against application-specific wiring requirements and equipment documentation.

Q: What is the difference in RoHS compliance between these parts?

A: The B53TP50CH meets RoHS compliance standards. The GN350ASZH achieves ROHS3 compliance, representing a more recent regulatory iteration. Both are acceptable for applications requiring RoHS-compliant components.

Q: Does the GN350ASZH support DC input control signals?

A: Yes. The GN350ASZH input specification includes 24–255VAC/DC, enabling operation with both AC and DC control sources. The B53TP50CH input is specified as 90–140VAC only.

Q: Can the GN350ASZH be panel-mounted if the B53TP50CH is chassis-mounted?

A: The GN350ASZH supports both chassis mount and panel mount configurations, providing installation flexibility. Mechanical mounting interface compatibility with existing equipment must be confirmed before substitution.

Q: Are both parts suitable for zero-cross switching applications?

A: Yes. Both the B53TP50CH and GN350ASZH feature AC output with zero-cross switching capability, maintaining consistent switching behavior across equivalent designs.
