HA4890 Solid State Relay SPST-NO 90A 48-530V Equivalent & Substitute Parts

Part Overview

The HA4890 is an active Sensata-Crydom solid state relay (SSR) with SPST-NO (1 Form A) configuration, rated for 90A load current and 48-530V output voltage range. 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 manufactured. Equivalent and substitute parts are identified when operational parameters fall within the allowable electrical and mechanical specifications for this SSR category, enabling direct replacement in applications where load current, voltage ratings, and control characteristics remain compatible.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HA4890 is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A)
• Output Type: Must be AC with zero-cross switching
• Mounting Type: Must be chassis mount
• Package / Case: Must be hockey puck form factor
• Termination Style: Must be screw terminal
• Load Current: Substitute must meet or exceed 90A rating
• Load Voltage Range: Substitute must cover or exceed the 48-530V range
• Control Input Voltage: Substitute must be compatible with 90-280VAC control signal

Two substitute parts meet these criteria: 84134141 (Sensata-Crydom GN series, 100A, 48-660V) and 84137141N (Crouzet GN series, 100A, 48-660V). Both maintain identical circuit topology, output switching characteristics, and mechanical form factor while providing higher current capacity and extended voltage range.

Parameter Comparison

Engineering Selection Recommendations

84134141 (Sensata-Crydom GN Series): This substitute maintains the same manufacturer lineage as the HA4890 and provides 100A capacity with extended 48-660V load voltage range. It carries ROHS3 compliance and is REACH affected. Control input voltage remains 90-280VAC, matching the original specification. This part is suitable for direct replacement in applications requiring higher current margin or extended voltage operation within the same manufacturer ecosystem.

84137141N (Crouzet GN Series): This substitute offers equivalent electrical performance with 100A capacity and 48-660V load voltage range. It features a broader control input voltage window (20-265VAC), providing greater flexibility for lower-voltage control circuits. RoHS compliance is maintained, and REACH status is unaffected. Packaging is supplied in box format rather than bulk. This part is suitable for applications where lower control voltage operation is beneficial or where cross-manufacturer qualification is acceptable.

Both substitutes are active products with current manufacturing status, ensuring long-term availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the 84134141 or 84137141N directly replace the HA4890 in existing applications?

A: Yes, both substitutes maintain identical circuit configuration (SPST-NO), output switching type (AC zero-cross), mounting method (chassis mount), and physical form factor (hockey puck). Load current capacity is higher (100A vs. 90A), and load voltage range is extended (48-660V vs. 48-530V), making them electrically compatible for direct replacement.

Q: What is the difference in control input voltage between the substitutes?

A: The HA4890 and 84134141 both accept 90-280VAC control input. The 84137141N accepts a broader range of 20-265VAC, allowing operation with lower control voltage sources. If your application uses control voltages below 90VAC, the 84137141N is the appropriate selection.

Q: Are there packaging differences between these parts?

A: The HA4890 and 84134141 are supplied in bulk packaging. The 84137141N is supplied in box packaging. This affects receiving, storage, and handling procedures but does not impact electrical or mechanical performance.

Q: What compliance certifications should I verify for my application?

A: The HA4890 is RoHS compliant. The 84134141 is ROHS3 compliant and REACH affected. The 84137141N is RoHS compliant and REACH unaffected. Verify your application's compliance requirements before selection, particularly if REACH or ROHS3 certification is mandated.

Q: Can I use a substitute with higher current rating in a lower-current application?

A: Yes. The 100A-rated substitutes (84134141 and 84137141N) are suitable for applications originally designed for 90A operation. Higher current capacity does not degrade performance in lower-current circuits.

Q: What is the significance of the extended voltage range in the substitutes?

A: The substitutes extend the maximum load voltage from 530V to 660V. If your application operates at voltages between 530V and 660V, the substitutes enable operation in this extended range. For applications operating within the original 48-530V window, both parts perform identically.
