HD6090-10 Equivalent & Substitute Parts

Part Overview

The HD6090-10 is a solid-state relay (SSR) manufactured by Sensata-Crydom, configured as a SPST-NO (1 Form A) device in a hockey puck package. This relay is designed for AC load switching applications with input control voltage ranging from 3 to 32 VDC and load voltage capability from 48 to 660 V at 90 A. The part is currently active in production and RoHS3 compliant. Substitute parts are identified when inventory constraints, application-specific voltage requirements, or load current specifications necessitate alternative models that maintain functional compatibility within the specified parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HD6090-10 is determined by the following critical parameters: circuit configuration (SPST-NO), package type (hockey puck), mounting method (chassis mount), termination style (screw terminal), and output type (AC). Load current and voltage ranges define the operational envelope within which substitutes must function. The identified substitute parts maintain the same circuit topology and physical form factor while offering variations in load current capacity (90 A to 100 A) and load voltage range (24 V ~ 500 V to 48 V ~ 660 V). Input control voltage compatibility (3 ~ 32 VDC to 4 ~ 32 VDC) and RoHS compliance status are secondary considerations that do not preclude substitution but inform selection based on application requirements and regulatory obligations.

Parameter Comparison

Engineering Selection Recommendations

84134340 (Sensata-Crydom): This substitute maintains identical load voltage range (48 V ~ 660 V) and manufacturer lineage with the HD6090-10. The load current rating increases to 100 A, providing additional capacity margin. Input voltage range begins at 4 VDC rather than 3 VDC, which may affect applications requiring operation below 4 VDC. RoHS compliance is maintained. This part is suitable for applications where higher current capacity is beneficial and input voltage does not fall below 4 VDC.

84138150N (Crouzet): This substitute is manufactured by Crouzet and maintains the 90 A load current rating. The load voltage range is reduced to 24 V ~ 500 V, which restricts operation in applications requiring voltages above 500 V or below 24 V. The zero-cross switching feature is included in the output type specification. Input voltage range is 4 ~ 32 VDC. RoHS compliance is maintained. This part is suitable for applications operating within the 24 V ~ 500 V load voltage envelope where zero-cross switching is acceptable or beneficial.

Frequently Asked Questions (FAQ)

Q: Can the 84134340 be used in place of the HD6090-10 in all applications?

A: The 84134340 is compatible with applications where the input control voltage remains at or above 4 VDC. If your application requires control voltage operation below 4 VDC, the HD6090-10 is required. The higher current rating (100 A vs. 90 A) does not create incompatibility.

Q: What is the primary limitation of the 84138150N substitute?

A: The 84138150N has a reduced load voltage range of 24 V ~ 500 V compared to the HD6090-10 range of 48 V ~ 660 V. This part cannot be used in applications requiring load voltages above 500 V or below 24 V.

Q: Are all three parts physically interchangeable?

A: Yes. All three parts share the same hockey puck package, chassis mount configuration, and screw terminal termination style, enabling direct physical replacement in the same mounting location.

Q: Does the zero-cross switching feature of the 84138150N affect compatibility?

A: Zero-cross switching is an additional feature that does not prevent substitution. It may improve performance in certain AC load applications by reducing electromagnetic interference, but it does not create incompatibility with systems designed for standard AC switching.

Q: Which substitute should be selected for maximum voltage range coverage?

A: The 84134340 maintains the full 48 V ~ 660 V load voltage range of the HD6090-10, making it the appropriate choice when maximum voltage range is required.

Q: Are there input voltage considerations when selecting a substitute?

A: Yes. The HD6090-10 operates with input voltage as low as 3 VDC, while both substitutes require a minimum of 4 VDC. Verify that your control circuit operates at or above 4 VDC before selecting either substitute.
