HA6025 Solid State Relay SPST-NO 25A 48-660V Equivalent & Substitute Parts

Part Overview

The HA6025 is an active Sensata-Crydom solid state relay (SSR) with SPST-NO (1 Form A) configuration, rated for 25A load current across 48V to 660V AC output. This hockey puck-style chassis mount relay operates with zero-cross switching and accepts 90-280VAC input control voltage. The part is RoHS compliant and actively manufactured. Substitute parts are identified when original inventory is unavailable or when alternative manufacturers' equivalent specifications meet application requirements within the defined electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HA6025 is determined by matching the following critical parameters: SPST-NO circuit configuration, 25A load current capacity, 48-660V load voltage range, AC zero-cross output type, hockey puck package form factor, screw terminal termination, and chassis mount orientation. Input control voltage tolerance and RoHS compliance status are secondary considerations that do not disqualify substitution when primary electrical and mechanical parameters align.

The substitute parts 84134111 (Sensata-Crydom GN series) and 84137111N (Crouzet GN series) satisfy all primary substitution criteria. The 84134111 maintains identical electrical specifications within the Sensata-Crydom product family. The 84137111N, manufactured by Crouzet, meets all load and circuit requirements with a slightly narrower input voltage range (20-265VAC versus 90-280VAC), which remains compatible with standard industrial control applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and meet RoHS compliance requirements. The HA6025 and 84134111 are both Sensata-Crydom products with identical electrical specifications and represent direct manufacturer equivalents within the same product family. The 84137111N from Crouzet provides a cross-manufacturer substitute with equivalent load handling and circuit performance; its input voltage range of 20-265VAC encompasses the standard 90-280VAC control signal range, ensuring functional compatibility in typical industrial control circuits.

Selection between these parts should be based on availability, supply chain requirements, and packaging preference. The HA6025 and 84134111 are supplied in bulk packaging, while 84137111N is supplied in box packaging. All three parts are actively manufactured and in stock.

Frequently Asked Questions (FAQ)

Q: Can 84134111 directly replace HA6025 in existing applications? A: Yes. Both parts are Sensata-Crydom products with identical electrical specifications, circuit configuration, load ratings, and package form factor. No circuit modifications are required.

Q: Is the Crouzet 84137111N compatible with HA6025 applications? A: Yes. The 84137111N meets all critical electrical and mechanical parameters: 25A load current, 48-660V load voltage range, SPST-NO configuration, AC zero-cross output, hockey puck package, and screw terminal termination. The input voltage range of 20-265VAC is compatible with standard industrial control applications that typically operate within the 90-280VAC specification.

Q: What is the difference between bulk and box packaging for these relays? A: Packaging type affects storage, handling, and logistics but does not alter electrical performance or mechanical fit. Bulk packaging (HA6025, 84134111) is suitable for high-volume manufacturing environments. Box packaging (84137111N) provides individual unit protection and is common for lower-volume or field replacement scenarios.

Q: Are there any compliance differences between these parts? A: All three parts are RoHS compliant. The 84134111 carries ROHS3 certification. The HA6025 and 84137111N carry standard RoHS certification. The 84137111N is REACH unaffected, while 84134111 is REACH affected. These compliance variations do not affect electrical substitution eligibility.

Q: Can these relays be used interchangeably in the same circuit board layout? A: Yes. All three parts share identical mounting type (chassis mount), package style (hockey puck), and termination method (screw terminal), enabling direct mechanical and electrical interchange without layout modifications.
