HD6050GHT Solid State Relay - Equivalent & Substitute Parts

Part Overview

The HD6050GHT is an active Sensata-Crydom solid state relay (SSR) designed for industrial AC switching applications. This SPST-NO (1 Form A) hockey puck relay operates with a 3–32 VDC input and controls loads up to 50 A across 48–660 V AC circuits with zero-cross switching capability. The part is RoHS compliant and carries unlimited moisture sensitivity rating (MSL 1), making it suitable for general industrial environments without special storage requirements. Equivalent and substitute parts are identified based on matching critical electrical parameters: circuit configuration, load current capacity, input voltage range, output voltage range, termination style, and physical package form.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HD6050GHT is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain identical switching logic
• Load Current Capacity: Must be rated for 50 A minimum
• Input Voltage Range: Must accommodate 3–32 VDC control signals
• Output Voltage Range: Must support the full 48–660 V load voltage window
• Output Type: Must feature AC switching with zero-cross capability
• Termination Style: Must use screw terminals for direct connection compatibility
• Package Form: Must be hockey puck configuration for mechanical fit
• Compliance: Must maintain RoHS compliance and MSL 1 rating

The Crouzet 84138120N meets these substitution criteria with the exception of output voltage range (24–500 V versus 48–660 V), which represents a narrower operating window. This part is classified as a manufacturer-recommended substitute where load voltage requirements do not exceed 500 V.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (HD6050GHT): Select this part for applications requiring the full 48–660 V load voltage range. Both the HD6050GHT and 84138120N are active products with current manufacturing status and full RoHS compliance, ensuring long-term availability and regulatory alignment.

Substitute Part (84138120N): The Crouzet 84138120N is suitable for applications where load voltage does not exceed 500 V. This part maintains identical circuit configuration, current rating, termination style, and package form. The input voltage range (4–32 VDC) is compatible with most control systems using the primary part, with the exception of applications requiring control signals below 4 VDC.

Both parts carry ECCN EAR99 classification and are subject to the same export control framework. Selection between these parts should be based solely on load voltage requirements and input voltage floor compatibility.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 84138120N replace the HD6050GHT in all applications?

A: No. The 84138120N has a maximum load voltage rating of 500 V, compared to 660 V for the HD6050GHT. Use the 84138120N only in applications where load voltage does not exceed 500 V. For applications requiring operation above 500 V, the HD6050GHT is the only suitable option.

Q: What is the minimum input voltage difference between these parts?

A: The HD6050GHT operates from 3 VDC minimum, while the 84138120N requires 4 VDC minimum. Applications using control signals between 3–4 VDC require the HD6050GHT.

Q: Are both parts mechanically interchangeable?

A: Yes. Both parts use hockey puck packaging with screw terminal connections and chassis mount configuration. Physical installation is identical.

Q: Do both parts support zero-cross switching?

A: Yes. Both the HD6050GHT and 84138120N feature AC output with zero-cross switching capability, ensuring synchronized load switching at AC voltage zero crossings.

Q: Are there storage or handling differences between these parts?

A: No. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard industrial storage conditions apply to both.

Q: What is the load current capacity for both parts?

A: Both parts are rated for 50 A continuous load current. This parameter is identical across both options.
