CSD2475 Equivalent & Substitute Parts

Part Overview

The CSD2475 is a solid-state relay (SSR) manufactured by Sensata-Crydom, configured as a SPST-NO (1 Form A) device in a hockey puck package. This component is rated for 75A load current with input voltage range of 3.5–15VDC and load voltage range of 24–280VAC, featuring zero-cross switching for AC applications. The CSD2475 is classified as obsolete, necessitating identification of equivalent substitute parts for ongoing procurement and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CSD2475 is determined by the following critical electrical and mechanical parameters:

• Circuit Configuration: SPST-NO (1 Form A) topology
• Load Current Rating: 75 A minimum
• Output Type: AC with zero-cross switching capability
• Package / Case: Hockey puck form factor
• Termination Style: Screw terminal connections
• Mounting Type: Chassis mount configuration

Substitute parts must maintain compatibility across these parameters. Load voltage and input voltage ranges may vary within acceptable operational limits for the application. Substitute parts are grouped by their alignment with these core specifications and their current product status.

Engineering Selection Recommendations

Primary Recommendation: 84134030

The 84134030 is the manufacturer-recommended substitute for the CSD2475. This part maintains identical electrical specifications (75A load current, 24–280VAC load voltage range, SPST-NO configuration, AC zero-cross output) and mechanical compatibility (hockey puck package, screw terminals, chassis mount). The 84134030 carries Active product status and RoHS compliance, ensuring long-term availability and regulatory alignment.

Secondary Recommendation: CSW2475

The CSW2475 is a direct Sensata-Crydom substitute with identical load current and voltage specifications. It features an expanded input voltage range (3–32VDC versus 3.5–15VDC) and ROHS3 compliance. The CSW2475 is classified as Last Time Buy, indicating limited future availability.

Alternative Recommendation: 84137130N

The 84137130N, manufactured by Crouzet, maintains the 75A load current and SPST-NO configuration with AC zero-cross switching. This part supports an extended load voltage range (48–660VAC) and expanded input voltage range (4–32VDC). The 84137130N is Active status with RoHS compliance. Selection of this part is appropriate when the application requires higher load voltage capability.

Frequently Asked Questions (FAQ)

Q: Can the CSW2475 directly replace the CSD2475?

A: Yes. The CSW2475 maintains identical load current (75A), load voltage range (24–280VAC), circuit configuration (SPST-NO), output type (AC zero-cross), package (hockey puck), and termination style (screw terminal). The expanded input voltage range (3–32VDC) provides additional operational flexibility.

Q: What is the difference between the 84134030 and 84137130N?

A: Both parts maintain the 75A load current and SPST-NO configuration. The primary difference is load voltage range: the 84134030 supports 24–280VAC, while the 84137130N supports 48–660VAC. The 84137130N is manufactured by Crouzet rather than Sensata-Crydom. Selection depends on the specific load voltage requirements of the application.

Q: Is the hockey puck package consistent across all substitute parts?

A: Yes. All substitute parts (CSW2475, 84134030, 84137130N) use the hockey puck package with screw terminal termination and chassis mount configuration, ensuring mechanical compatibility with existing installations.

Q: What is the significance of product status classifications?

A: Product status indicates availability trajectory. Active status (84134030, 84137130N) indicates ongoing manufacture and long-term availability. Last Time Buy status (CSW2475) indicates limited future production. Obsolete status (CSD2475) indicates discontinuation.

Q: Are all substitute parts RoHS compliant?

A: Yes. The CSW2475 is ROHS3 compliant. The 84134030 and 84137130N are RoHS compliant. All substitute parts meet current regulatory requirements.

Q: Can the 84137130N be used in applications designed for the CSD2475?

A: The 84137130N is electrically compatible for applications operating within the 24–280VAC load voltage range. The extended load voltage capability (48–660VAC) does not restrict operation at lower voltages. Verification of input voltage compatibility (4–32VDC for 84137130N versus 3.5–15VDC for CSD2475) is required for specific applications.
