HA6090 Solid State Relay SPST-NO 90A 48-660V Equivalent & Substitute Parts

Part Overview

The HA6090 is an active Sensata-Crydom solid state relay (SSR) with SPST-NO (1 Form A) configuration, rated for 90A load current at 48-660V output voltage. This hockey puck-style chassis mount relay operates with AC zero-cross switching and accepts 90-280VAC input control voltage. The part is RoHS compliant and actively produced. Substitute parts are identified when inventory constraints, packaging preferences, or compliance requirements necessitate alternative sourcing while maintaining functional equivalence within the specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HA6090 is determined by the following critical parameters: SPST-NO circuit configuration, AC zero-cross output type, hockey puck package form factor, screw terminal termination, and chassis mount orientation. Load voltage range (48-660V) and output current capability establish the functional envelope for substitution.

The identified substitute parts (84134141 and 84137141N) maintain identical circuit topology, output switching characteristics, package geometry, and termination method. Both substitutes support the same load voltage range and chassis mount configuration. Input voltage tolerance and load current ratings differ as specified in the parameter comparison table below.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts exceed the HA6090 load current specification (100A vs. 90A), providing operational margin within the same 48-660V load voltage envelope. Part 84134141 maintains Sensata-Crydom manufacturing continuity with ROHS3 compliance and REACH affected status. Part 84137141N offers Crouzet sourcing with RoHS compliance and REACH unaffected status, available in box packaging rather than bulk.

Selection between HA6090 and substitutes depends on input voltage tolerance requirements. The HA6090 and 84134141 both specify 90-280VAC input range. Part 84137141N accepts a wider input range (20-265VAC), suitable for applications with lower minimum control voltage requirements. All three parts maintain identical load voltage capability and zero-cross AC switching characteristics.

Frequently Asked Questions (FAQ)

Q: Can 84134141 directly replace HA6090 in existing designs? A: Yes. Both parts share identical circuit configuration (SPST-NO), output type (AC zero-cross), load voltage range (48-660V), package form factor (hockey puck), and termination method (screw terminal). The 84134141 provides 100A load current versus the HA6090's 90A, maintaining full compatibility within the specified electrical envelope.

Q: What is the functional difference between 84137141N and the other two parts? A: The 84137141N is manufactured by Crouzet rather than Sensata-Crydom and specifies a wider input voltage range (20-265VAC vs. 90-280VAC). Load voltage, current rating, circuit topology, and package geometry remain identical. This part is available in box packaging rather than bulk.

Q: Are all three parts suitable for the same load voltage applications? A: Yes. All three parts support 48-660V load voltage range with identical AC zero-cross switching behavior. Load current ratings (90A for HA6090, 100A for both substitutes) do not affect voltage compatibility.

Q: Does packaging type affect electrical performance? A: No. The HA6090 (bulk packaging) and 84137141N (box packaging) are electrically identical. Packaging type affects logistics and inventory management only, not functional characteristics or performance.

Q: Which substitute should be selected for new designs? A: Selection depends on control voltage requirements and supply chain preferences. For 90-280VAC input control voltage, either HA6090 or 84134141 applies. For applications requiring lower minimum input voltage (20VAC), 84137141N is appropriate. All three maintain identical load switching performance and voltage range.
