HA6050 Solid State Relay SPST-NO 50A 48-660V

Part Overview

The HA6050 is a solid state relay (SSR) manufactured by Sensata-Crydom, configured as a single-pole single-throw normally open (SPST-NO) device rated for 50A load current across 48V to 660V output range. The unit features AC zero-cross switching capability with screw terminal connections in a hockey puck form factor, designed for chassis mount applications. This active product is RoHS compliant and suitable for industrial switching applications requiring reliable AC load control.

Alternative models become necessary when addressing specific supply chain constraints, regional compliance requirements, or when preferred input voltage ranges differ from the standard 90-280VAC specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HA6050 is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A)
• Load Current Rating: Must be 50 A minimum
• Output Voltage Range: Must cover 48 V – 660 V
• Output Type: Must be AC with zero-cross switching
• Package / Case: Must be Hockey Puck form factor
• Termination Style: Must be Screw Terminal
• Mounting Type: Must be Chassis Mount

Two substitute parts meet these criteria: the Sensata-Crydom 84134121 (GN series) and the Crouzet 84137121N (GN series). Both maintain identical electrical performance specifications and mechanical compatibility with the HA6050.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and meet RoHS compliance requirements. The HA6050 and 84134121 are both Sensata-Crydom products with identical input voltage specifications (90–280VAC), making either suitable for standard applications within this input range. The 84137121N from Crouzet extends the input voltage floor to 20VAC, providing broader input compatibility for applications requiring lower control voltage thresholds. The 84134121 carries ROHS3 compliance with REACH affected status, while the HA6050 and 84137121N maintain standard RoHS compliance with REACH unaffected status. Selection should be based on specific input voltage requirements and regional compliance obligations.

Frequently Asked Questions (FAQ)

Q: Can the 84134121 directly replace the HA6050 in existing installations?

A: Yes. Both parts are Sensata-Crydom products with identical electrical ratings (50A, 48–660V output, 90–280VAC input), circuit configuration (SPST-NO), output type (AC zero-cross), and mechanical form factor (hockey puck, screw terminal, chassis mount). No circuit modifications are required.

Q: What is the primary difference between the HA6050 and the Crouzet 84137121N?

A: The 84137121N accepts input voltage as low as 20VAC, compared to the HA6050's 90VAC minimum. All other electrical and mechanical specifications are equivalent. The 84137121N is supplied in box packaging rather than bulk.

Q: Are there compliance differences between these three parts?

A: The HA6050 and 84137121N are RoHS compliant with REACH unaffected status. The 84134121 is ROHS3 compliant with REACH affected status. All three meet industrial switching application requirements.

Q: Can these parts be used interchangeably in the same circuit board layout?

A: Yes. All three parts share identical mechanical specifications: hockey puck form factor, screw terminal connections, and chassis mount configuration. No PCB or mechanical redesign is necessary for substitution.

Q: Which part should be selected for applications with variable input voltage below 90VAC?

A: The Crouzet 84137121N is the only option among the three, as it operates with input voltage as low as 20VAC. The HA6050 and 84134121 require minimum 90VAC input.
