HD4890-10 Solid State Relay - Equivalent & Substitute Parts

Part Overview

The HD4890-10 is an active Sensata-Crydom solid state relay (SSR) featuring SPST-NO (1 Form A) switching configuration in a hockey puck package. This AC output relay is rated for 90A load current across 48V to 530V operating range with 3-32VDC control input. The part is RoHS compliant and currently in production with 20,399 units in stock. Substitute parts are identified when inventory constraints, voltage range requirements, or current capacity specifications necessitate alternative component selection while maintaining circuit compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HD4890-10 is determined by the following critical parameters:

• Circuit configuration must remain SPST-NO (1 Form A)
• Output type must be AC or AC with zero-cross capability
• Control voltage range must accommodate 3-32VDC input
• Load voltage range must overlap or exceed the 48V-530V specification
• Load current rating must equal or exceed 90A
• Mounting type must be Chassis Mount
• Termination style must be Screw Terminal
• Package must be Hockey Puck format
• RoHS compliance status must be maintained

Two substitute parts meet these criteria: Sensata-Crydom 84134340 and Crouzet 84138150N. Both maintain identical circuit topology, mounting configuration, and termination style while offering variations in current capacity and voltage range specifications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and RoHS compliance, ensuring regulatory alignment and supply chain continuity.

84134340 (Sensata-Crydom): This substitute provides 10A additional current capacity (100A vs. 90A) and extends the maximum load voltage to 660V. The control voltage minimum increases from 3VDC to 4VDC. This part is suitable for applications requiring higher current headroom or extended voltage range within the same manufacturer ecosystem.

84138150N (Crouzet): This substitute maintains the 90A current rating and adds zero-cross switching capability. The load voltage range is 24V-500V, which covers the lower end of the HD4890-10 specification but does not extend to 530V maximum. The control voltage minimum is 4VDC. This part is suitable for applications where zero-cross switching is beneficial and load voltage does not exceed 500V.

Selection between substitutes depends on specific application voltage and current requirements. Both alternatives are in active production with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the 84134340 be used as a direct replacement for the HD4890-10?

A: The 84134340 is functionally compatible for applications operating within the HD4890-10 voltage and current specifications. The 84134340 offers higher current capacity (100A) and extended voltage range (48V-660V), making it suitable for the same control circuits. The control voltage minimum increases from 3VDC to 4VDC; verify your control circuit operates at 4VDC or higher.

Q: What is the difference between the AC and AC with zero-cross output types?

A: Both output types switch AC loads. The zero-cross variant (84138150N) synchronizes switching to the AC waveform zero-crossing point, reducing electromagnetic interference and switching stress. Standard AC output (HD4890-10, 84134340) switches at any point in the AC cycle.

Q: Is the 84138150N suitable for applications requiring 530V load voltage?

A: No. The 84138150N maximum load voltage is 500V. For applications requiring operation at 530V, use the HD4890-10 or 84134340.

Q: Are all three parts available in the same packaging format?

A: Yes. All three parts use hockey puck package format with screw terminal termination and chassis mount configuration, ensuring mechanical and electrical compatibility within the same mounting footprint.

Q: What is the minimum control voltage for each part?

A: HD4890-10 operates with 3-32VDC control input. Both 84134340 and 84138150N require 4-32VDC control input. Verify your control circuit provides at least 4VDC if substituting with either alternative.
