CSW2475-10 Equivalent & Substitute Parts

Part Overview

The CSW2475-10 is a solid-state relay (SSR) manufactured by Sensata Technologies, configured as a single-pole single-throw normally-open (SPST-NO) device rated for 75A load current with input voltage range of 3–32VDC and output voltage range of 24–280VAC. The device features a hockey puck form factor with screw terminal connections and is RoHS compliant.

This part is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain system functionality and ensure continued availability for replacement and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSW2475-10 is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A)
• Output Type: Must be AC
• 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
• RoHS Compliance: Must be RoHS compliant

Three substitute parts meet these criteria with varying degrees of parameter alignment:

1. D2475-10 (Sensata-Crydom): Direct parameter match with active product status
2. 84137330N (Crouzet): Extended voltage range (48–660V); input voltage minimum increased to 4VDC
3. ASR-SN240D80RW-L (Altran Magnetics): Increased load current rating (80A); package form factor differs (Module vs. Hockey Puck)

Parameter Comparison

Engineering Selection Recommendations

D2475-10 (Sensata-Crydom) is the primary substitute. It maintains identical electrical specifications and physical form factor while offering active product status and continued manufacturer support. This part is suitable for direct replacement in existing designs.

84137330N (Crouzet) is a functional substitute with extended load voltage capability (48–660V). The minimum input voltage is increased to 4VDC, which may affect compatibility in systems requiring operation below 4VDC. This part is suitable for applications where the extended voltage range provides design flexibility.

ASR-SN240D80RW-L (Altran Magnetics) provides increased load current capacity (80A) and maintains the original voltage specifications. The package form factor differs (Module vs. Hockey Puck), requiring mechanical re-evaluation for mounting compatibility. This part is suitable for applications requiring higher current capacity with mechanical redesign consideration.

All three substitutes maintain RoHS compliance and screw terminal termination, ensuring regulatory and interface compatibility.

Frequently Asked Questions (FAQ)

Q: Can D2475-10 be used as a direct replacement for CSW2475-10?

A: Yes. D2475-10 matches all critical electrical and mechanical parameters: SPST-NO circuit, 75A load current, 3–32VDC input, 24–280V output, hockey puck form factor, and screw terminal termination. Both are RoHS compliant.

Q: What is the key difference between 84137330N and the original CSW2475-10?

A: The 84137330N supports an extended output voltage range of 48–660V compared to 24–280V. The minimum input voltage is 4VDC instead of 3VDC. Load current remains 75A. The hockey puck form factor is identical.

Q: Is ASR-SN240D80RW-L compatible with existing mechanical mounting?

A: ASR-SN240D80RW-L uses a Module package form factor instead of the hockey puck configuration. Mechanical re-evaluation is required to confirm mounting compatibility with existing chassis or enclosure designs.

Q: Are all three substitutes RoHS compliant?

A: Yes. D2475-10 and 84137330N are RoHS compliant. ASR-SN240D80RW-L is ROHS3 compliant, which meets current RoHS requirements.

Q: Which substitute should be selected for new designs?

A: D2475-10 is recommended for new designs requiring direct parameter equivalence. ASR-SN240D80RW-L is recommended if increased current capacity (80A) is beneficial. 84137330N is recommended if extended voltage range (48–660V) is required.
