HA6050G Solid State Relay - Equivalent & Substitute Parts

Part Overview

The HA6050G is a Solid State Relay (SSR) manufactured by Sensata-Crydom, configured as a SPST-NO (Single Pole Single Throw - Normally Open) device in a Hockey Puck package. This relay is designed for AC load switching applications with a 50A capacity across a wide voltage range of 48V to 660V. The product is currently Active in production status with full RoHS compliance. Alternative equivalent parts may be required due to supply chain considerations, inventory availability, or specific application requirements while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HA6050G is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) only
• Load Current Rating: Must be 50 A
• Load Voltage Range: Must support 48 V ~ 660 V minimum
• Output Type: Must be AC with Zero Cross functionality
• Package Type: Must be Hockey Puck form factor
• Mounting Type: Must be Chassis Mount
• Termination Style: Must be Screw Terminal
• RoHS Compliance: Must be RoHS Compliant

The substitute part 84137121N manufactured by Crouzet meets all mandatory electrical and mechanical parameters. The input voltage range differs (20 ~ 265 VAC versus 90 ~ 280 VAC), but this represents a broader input acceptance window and does not restrict substitution capability. Both parts are Active products with current manufacturing status and full regulatory compliance.

Parameter Comparison

*The 84137121N input voltage range (20 ~ 265 VAC) encompasses the HA6050G range (90 ~ 280 VAC) with partial overlap. The Crouzet part accepts lower minimum input voltage and slightly lower maximum input voltage.

Engineering Selection Recommendations

Both the HA6050G and 84137121N are Active production parts with full RoHS compliance and REACH unaffected status. Selection between these parts should be based on:

• Supply availability: Both manufacturers maintain current inventory
• Input voltage requirements: If your application requires input voltages below 90 VAC or above 265 VAC, the HA6050G is the appropriate choice. If your application operates within the 90 ~ 265 VAC window, either part is suitable.
• Packaging and logistics: The HA6050G is supplied in Bulk packaging, while the 84137121N is supplied in Box packaging. Verify packaging requirements for your procurement process.
• Regulatory compliance: Both parts meet identical compliance standards for RoHS and ECCN classifications.

Frequently Asked Questions (FAQ)

Q: Can the 84137121N replace the HA6050G in all applications?

A: The 84137121N is electrically and mechanically equivalent for applications where the input voltage remains within the 20 ~ 265 VAC range. If your circuit requires input voltages above 265 VAC or below 90 VAC, the HA6050G must be used.

Q: Are the Hockey Puck packages identical between these two parts?

A: Both parts use the Hockey Puck package form factor with Chassis Mount configuration and Screw Terminal termination. Physical dimensions and mounting interfaces are equivalent for direct substitution.

Q: What is the significance of the Zero Cross output type?

A: Zero Cross switching means the relay activates or deactivates only when the AC voltage waveform crosses zero volts. This reduces electromagnetic interference and switching noise in AC load applications. Both parts feature this functionality.

Q: Do both parts have the same load current and voltage ratings?

A: Yes. Both the HA6050G and 84137121N are rated for 50 A load current and support load voltages from 48 V to 660 V. These critical parameters are identical.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
