CSW2475 Solid State Relay - Equivalent & Substitute Parts

Part Overview

The CSW2475 is a solid state relay (SSR) manufactured by Sensata-Crydom, classified as a SPST-NO (Single Pole Single Throw - Normally Open) device in a hockey puck form factor. This component is rated for 75A load current with input voltage range of 3–32VDC and output voltage range of 24–280V AC with zero-cross switching capability. The CSW2475 is designated as Last Time Buy, indicating discontinued production status. Identifying equivalent and substitute parts is necessary to ensure continued availability and support for applications currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSW2475 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
• Voltage - Input: Must support 3–32VDC range
• Voltage - Load: Must support minimum 24–280V range
• Load Current: Must support minimum 75A
• Mounting Type: Must be Chassis Mount
• Termination Style: Must be Screw Terminal

Three substitute parts meet these criteria with the following distinctions:

D2475 (Sensata-Crydom): Direct equivalent with identical electrical specifications and hockey puck package. Active product status.

84137130N (Crouzet): Meets core substitution criteria with extended voltage range (48–660V output) and identical 75A current rating. Hockey puck package. Voltage input range extends to 4–32VDC.

ASR-SN240D80ZW-L (Altran Magnetics, LLC): Meets substitution criteria with 80A load current (exceeds 75A requirement) and identical input/output voltage ranges. Module package form factor differs from hockey puck.

Parameter Comparison

Engineering Selection Recommendations

D2475 is the primary substitute for the CSW2475. Both components are manufactured by Sensata-Crydom with identical electrical specifications, package form factor, and RoHS3 compliance. The D2475 maintains active product status, ensuring long-term availability and supply chain continuity.

84137130N (Crouzet) is suitable for applications where extended output voltage range (48–660V) provides operational margin beyond the CSW2475 specification. The minimum input voltage increases to 4VDC; applications requiring operation below 4VDC input are not compatible. RoHS compliance is confirmed; REACH status differs from the CSW2475.

ASR-SN240D80ZW-L (Altran Magnetics, LLC) accommodates applications requiring higher load current capacity (80A versus 75A). The module package form factor requires mechanical redesign compared to hockey puck mounting. REACH status is unaffected, differing from the CSW2475. This option is suitable only when package form factor change is acceptable.

Frequently Asked Questions (FAQ)

Q: Can D2475 be used as a direct replacement for CSW2475?

A: Yes. D2475 is electrically and mechanically equivalent to CSW2475, with identical voltage ratings, current capacity, circuit configuration, and hockey puck package. Both are ROHS3 compliant. The primary difference is product status: D2475 is active while CSW2475 is Last Time Buy.

Q: What is the key difference between 84137130N and CSW2475?

A: The 84137130N supports extended output voltage range (48–660V versus 24–280V) and has a minimum input voltage of 4VDC instead of 3VDC. Load current remains 75A. Both use hockey puck packages and screw terminals. Applications operating below 4VDC input or requiring output voltage below 48V are not compatible with 84137130N.

Q: Can ASR-SN240D80ZW-L replace CSW2475 in existing designs?

A: ASR-SN240D80ZW-L meets all electrical substitution criteria and provides higher current capacity (80A). However, the module package form factor differs from the hockey puck package of CSW2475. Mechanical redesign of mounting and thermal management may be required. Electrical compatibility is confirmed for applications within the 24–280V output and 3–32VDC input ranges.

Q: Are all substitute parts RoHS compliant?

A: Yes. CSW2475, D2475, and ASR-SN240D80ZW-L are ROHS3 compliant. 84137130N is RoHS compliant. All parts meet applicable environmental regulations for the specified applications.

Q: Which substitute offers the best long-term availability?

A: D2475 is the recommended choice for long-term availability. It is manufactured by the same supplier as the original CSW2475 (Sensata-Crydom), maintains active product status, and provides identical specifications and package form factor. This minimizes design changes and supply chain risk.
