Sensata-Crydom A2425E-10 Solid State Relay - Equivalent & Substitute Parts

Part Overview

The Sensata-Crydom A2425E-10 is an active SPST-NO (1 Form A) solid state relay in Hockey Puck package configuration, rated for 25A load current with AC output capability. This component is designed for chassis mount applications requiring switching of AC loads in the 24V to 280V range with 18-36VAC input control voltage. The part is ROHS3 compliant and REACH affected, with 958 units currently in stock. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when supply chain diversification is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the A2425E-10 is determined by the following critical parameters:

• Circuit configuration must be SPST-NO (1 Form A)
• Load current rating must be 25A minimum
• Package type must be Hockey Puck with Screw Terminal termination
• Mounting type must be Chassis Mount
• Output type must support AC switching
• Load voltage range must encompass or overlap the 24V to 280V specification
• Input voltage range must be compatible with 18-36VAC control signal

The Crouzet 84138013N meets these substitution criteria with compatible electrical ratings and identical mechanical packaging.

Parameter Comparison

Engineering Selection Recommendations

Both the Sensata-Crydom A2425E-10 and Crouzet 84138013N are active products with current manufacturing status. The A2425E-10 carries ROHS3 compliance and is REACH affected. The 84138013N is RoHS compliant and REACH unaffected. Selection between these parts should be based on regulatory requirements specific to the end application and regional compliance obligations. Both parts meet the core electrical and mechanical specifications for SPST-NO 25A AC relay applications in Hockey Puck configuration with Screw Terminal termination.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 84138013N directly replace the Sensata-Crydom A2425E-10?

A: The Crouzet 84138013N is electrically and mechanically compatible as a substitute. Both parts feature identical circuit configuration (SPST-NO), load current rating (25A), package type (Hockey Puck), and termination style (Screw Terminal). The input voltage range of the Crouzet part (20-265VAC/DC) encompasses the A2425E-10 specification (18-36VAC). The load voltage range of the Crouzet part (12-270V) is slightly lower at the upper limit compared to the A2425E-10 (24-280V), which may be a consideration for applications requiring the full 280V capability.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) The Crouzet 84138013N includes zero-cross switching capability, while the A2425E-10 does not specify this feature; (2) The Crouzet part accepts both AC and DC input voltage (20-265VAC/DC), whereas the A2425E-10 is specified for AC input only (18-36VAC); (3) Regulatory compliance differs: A2425E-10 is ROHS3 compliant and REACH affected, while 84138013N is RoHS compliant and REACH unaffected.

Q: Are there any load voltage limitations when substituting?

A: The Crouzet 84138013N has a maximum load voltage rating of 270V, compared to the A2425E-10 at 280V. Applications requiring switching at the full 280V specification should confirm that 270V operation is acceptable for the intended circuit.

Q: What packaging formats are available for these parts?

A: The Sensata-Crydom A2425E-10 is supplied in Bulk packaging, while the Crouzet 84138013N is supplied in Box packaging. Both parts use identical Hockey Puck mechanical package with Screw Terminal termination for chassis mount installation.
