CSW2410 Solid State Relay - Equivalent & Substitute Parts

Part Overview

The CSW2410 is a solid state relay (SSR) manufactured by Sensata Technologies, configured as a single-pole single-throw normally open (SPST-NO) device rated for 10A load current with input voltage range of 3–32VDC and load voltage range of 24–280VAC. The device features a hockey puck form factor with screw terminal connections and zero-cross switching capability for AC loads.

The CSW2410 is designated as Last Time Buy, indicating discontinued production. Equivalent substitute parts are available from active product lines that maintain identical or compatible electrical and mechanical specifications, ensuring continued availability for replacement and new applications.

Engineering Selection Recommendations

D2410 (Sensata-Crydom) is the primary direct substitute. It maintains identical electrical specifications and input voltage range (3–32 VDC) as the CSW2410, with active product status and equivalent RoHS3 compliance. This part is recommended for direct replacement in existing designs without modification.

84137000N (Crouzet) is a qualified alternative with active product status and RoHS compliance. The input voltage minimum threshold is 4 VDC (versus 3 VDC for CSW2410), which is compatible with standard 5V and higher control circuits. REACH Unaffected status may be advantageous in certain supply chain contexts. This part is suitable for applications where the 4 VDC minimum input threshold does not conflict with system requirements.

ASR-SI240D10Z-LR (Altran Magnetics) is a qualified alternative with active product status and ROHS3 compliance. The load voltage range begins at 48 V (versus 24 V for CSW2410), restricting use to applications with minimum load voltages of 48 VAC or higher. This part is suitable only for systems operating at 48 V or above. The input voltage minimum threshold is 4 VDC, compatible with standard control circuits.

Frequently Asked Questions (FAQ)

Q: Can D2410 replace CSW2410 in all applications? A: Yes. D2410 maintains identical input voltage range (3–32 VDC) and load voltage range (24–280 V), with equivalent electrical specifications and RoHS3 compliance. No circuit modifications are required.

Q: What is the key difference between 84137000N and CSW2410? A: The input voltage minimum threshold is 4 VDC for 84137000N versus 3 VDC for CSW2410. Both support the same load voltage range (24–280 V) and 10 A current rating. Selection depends on whether the control circuit operates below 4 VDC.

Q: Can ASR-SI240D10Z-LR be used in place of CSW2410? A: ASR-SI240D10Z-LR is compatible only in applications where the load voltage is 48 V or higher. The minimum load voltage specification is 48 V, compared to 24 V for CSW2410. It is not suitable for 24 V load applications.

Q: Are all substitutes available in the same packaging format? A: CSW2410 is supplied in bulk packaging. D2410 is also supplied in bulk. Both 84137000N and ASR-SI240D10Z-LR are supplied in box packaging. Procurement and handling procedures may differ accordingly.

Q: Do all substitutes meet the same environmental compliance standards? A: CSW2410 and D2410 are ROHS3 Compliant and REACH Affected. 84137000N is RoHS Compliant and REACH Unaffected. ASR-SI240D10Z-LR is ROHS3 Compliant and REACH Unaffected. Compliance requirements vary by application and regulatory jurisdiction.
