CSW2425H Solid State Relay SPST-NO 25A 24-280V Equivalent & Substitute Parts

Part Overview

The CSW2425H is a solid state relay (SSR) with SPST-NO (1 Form A) configuration manufactured by Sensata-Crydom. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new designs. The CSW2425H operates as a hockey puck-style chassis mount relay with 25A load capacity across 24V to 280V AC output range, controlled by 3V to 32VDC input signal.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CSW2425H are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Circuit configuration: SPST-NO (1 Form A)
• Output type: AC with zero cross capability
• Load current rating: 25 A minimum
• Load voltage range: Must encompass or exceed 24V to 280V
• Input voltage range: Must accommodate 3V to 32VDC control signal
• Mounting type: Chassis Mount
• Package type: Hockey Puck
• Termination style: Screw Terminal

Two substitute parts meet these criteria: the D2425H (Sensata-Crydom, active status) and the 84138010N (Crouzet, active status). Both maintain identical circuit configuration, load current, mounting, package, and termination specifications. Load voltage ranges differ slightly but remain compatible within the specified operating envelope.

Parameter Comparison

Engineering Selection Recommendations

D2425H (Sensata-Crydom): This part is the direct successor from the original manufacturer. It maintains identical electrical specifications to the CSW2425H across all critical parameters: input voltage range (3~32VDC), load voltage range (24~280V), and 25A current rating. The D2425H carries active product status and ROHS3 compliance, making it the primary choice for direct replacement in new designs and system upgrades. Packaging is bulk format.

84138010N (Crouzet): This manufacturer-recommended alternative provides equivalent functionality with minor parameter variations. Input voltage minimum is 4VDC (versus 3VDC on CSW2425H), and load voltage maximum is 270V (versus 280V). These differences are within acceptable tolerance for most industrial applications. The 84138010N is active status with RoHS compliance and box packaging. Selection of this part is appropriate when Crouzet supply chain or packaging requirements align with system needs.

Frequently Asked Questions (FAQ)

Q: Can the D2425H directly replace the CSW2425H without circuit modification? A: Yes. The D2425H maintains identical electrical specifications across input voltage (3~32VDC), load voltage (24~280V), load current (25A), circuit configuration (SPST-NO), and output type (AC, zero cross). Mechanical compatibility is confirmed through matching chassis mount, hockey puck package, and screw terminal termination.

Q: What is the significance of the load voltage difference between CSW2425H (24~280V) and 84138010N (12~270V)? A: The 84138010N operates at lower minimum voltage (12V versus 24V) and slightly lower maximum voltage (270V versus 280V). For applications operating within the 24~270V range, the 84138010N is fully compatible. Applications requiring operation below 24V or above 270V must use the D2425H or CSW2425H.

Q: Does the input voltage difference (3VDC minimum on CSW2425H versus 4VDC on 84138010N) affect compatibility? A: For control circuits operating at 4VDC or higher, both parts are compatible. Applications requiring control signal operation at 3VDC must use the CSW2425H or D2425H. Verify your control circuit voltage specification before selecting the 84138010N.

Q: What packaging formats are available for these substitute parts? A: The D2425H is supplied in bulk packaging. The 84138010N is supplied in box packaging. The original CSW2425H packaging format is not specified in available data. Confirm packaging requirements with your procurement process.

Q: Are there compliance differences between the substitute parts? A: The D2425H carries ROHS3 compliance, representing the current regulatory standard. The 84138010N carries RoHS compliance. Both meet current environmental and safety requirements. The D2425H is recommended for new designs subject to the most current compliance mandates.
