GN350ASR Equivalent & Substitute Parts

Part Overview

The GN350ASR is a solid-state relay (SSR) manufactured by Sensata-Crydom, classified as a 3PST-NO (3 Form A) configuration with 50A load capacity. This component is designed for AC output switching applications across industrial and control system environments. The part is currently in active production status with 1079 units available in inventory. Finding equivalent or substitute parts may be necessary due to supply chain constraints, regional availability, or specific application requirements that demand alternative mounting configurations or input voltage specifications.

Key Parameters

Substitute Part Grouping Explanation

The GN350ASZH is identified as a manufacturer-recommended substitute for the GN350ASR. Substitution eligibility is determined by the following critical parameters:

• Circuit configuration: Both parts maintain 3PST-NO (3 Form A) topology
• Load current capacity: Both rated at 50 A
• Output type: Both provide AC switching capability
• Termination style: Both use screw terminal connections
• Series classification: Both belong to the GN3 series
• Compliance standards: Both meet RoHS requirements

The GN350ASZH differs in input voltage range (24 ~ 255 VAC/DC versus 180 ~ 280 VAC), load voltage range (24 V ~ 510 V versus 48 V ~ 530 V), mounting configuration (Chassis Mount or Panel Mount versus DIN Rail), and output feature (includes Zero Cross capability). These differences establish distinct application contexts while maintaining core switching functionality.

Parameter Comparison

Engineering Selection Recommendations

Both the GN350ASR and GN350ASZH maintain active production status and meet current RoHS compliance requirements. The GN350ASR is optimized for DIN Rail mounting environments with input voltage specifications between 180 and 280 VAC. The GN350ASZH accommodates broader input voltage flexibility (24 ~ 255 VAC/DC) and supports alternative mounting configurations (Chassis Mount or Panel Mount), making it suitable for applications requiring different form factors or lower input voltage operation. Selection between these parts should be based on specific mounting requirements, input voltage availability, and load voltage operating range within the application circuit.

Frequently Asked Questions (FAQ)

Q: Can the GN350ASZH replace the GN350ASR in all applications?

A: Substitution is valid only when the application requirements align with the GN350ASZH specifications. The primary differences are mounting type (DIN Rail versus Chassis/Panel Mount), input voltage range (180 ~ 280 VAC versus 24 ~ 255 VAC/DC), and load voltage range (48 ~ 530 V versus 24 ~ 510 V). Verify that your circuit operates within the GN350ASZH input and load voltage parameters before substitution.

Q: What is the significance of the Zero Cross feature in the GN350ASZH?

A: The Zero Cross capability in the GN350ASZH provides switching synchronization at AC voltage zero-crossing points. This feature is specified in the product data and may influence performance in specific control applications. The GN350ASR does not include this feature.

Q: Are both parts suitable for the same load current applications?

A: Yes. Both the GN350ASR and GN350ASZH are rated for 50 A load current and maintain identical 3PST-NO circuit configuration, making them functionally equivalent for current-handling capacity.

Q: What mounting considerations apply when selecting between these parts?

A: The GN350ASR is designed for DIN Rail mounting, standard in industrial control cabinets. The GN350ASZH supports Chassis Mount or Panel Mount configurations, requiring different mechanical integration approaches. Select based on your enclosure design and available mounting infrastructure.

Q: Do both parts meet current environmental compliance standards?

A: Yes. The GN350ASR is RoHS Compliant, and the GN350ASZH is ROHS3 Compliant. Both parts satisfy current regulatory requirements for hazardous substance restrictions.
