CSE2475 Solid State Relay SPST-NO 75A 24-280V Equivalent & Substitute Parts

Part Overview

The CSE2475 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 15-32VDC and output voltage range of 24-280V. This active product features a hockey puck form factor with screw terminal connections and zero-cross AC output switching capability. Substitute parts are identified when equivalent electrical specifications, mechanical compatibility, and compliance certifications align with the original component's functional requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSE2475 is determined by the following critical parameters:

• Circuit configuration must be SPST-NO (1 Form A)
• Load current rating must be 75A
• Load voltage range must be 24-280V
• Output type must be AC with zero-cross switching
• Package form factor must be hockey puck
• Termination must be screw terminal
• Mounting type must be chassis mount
• RoHS compliance status must be maintained

The substitute part 84134030 (Sensata-Crydom GN series) meets all functional and mechanical requirements. While the input voltage range differs (3-32VDC versus 15-32VDC), the substitute accepts the full operating range of the original part, making it functionally compatible for applications using the CSE2475 within its specified input voltage window.

Parameter Comparison

Engineering Selection Recommendations

The CSE2475 and 84134030 are functionally equivalent for applications requiring SPST-NO solid state relay operation at 75A load current with AC zero-cross switching. Both parts maintain active product status and RoHS compliance. The 84134030 provides broader input voltage compatibility (3-32VDC) compared to the CSE2475 (15-32VDC), making it suitable for applications operating within either voltage specification. Selection between these parts should be based on availability, lead time, and existing supply chain qualification requirements.

Frequently Asked Questions (FAQ)

Q: Can the 84134030 directly replace the CSE2475 in existing designs?

A: Yes. Both parts share identical circuit configuration (SPST-NO), load current rating (75A), load voltage range (24-280V), output type (AC zero-cross), package form factor (hockey puck), and termination style (screw terminal). The 84134030 accepts the full input voltage range of the CSE2475.

Q: What is the significance of the different input voltage ranges?

A: The CSE2475 specifies 15-32VDC input, while the 84134030 specifies 3-32VDC input. For applications operating the CSE2475 within its 15-32VDC window, the 84134030 is fully compatible. The broader range of the 84134030 does not affect substitution eligibility.

Q: Are there any packaging or mounting differences?

A: No. Both parts use identical hockey puck form factor, chassis mount configuration, and screw terminal termination style.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the CSE2475 and 84134030 are RoHS compliant and carry active product status.

Q: What should be considered when selecting between these parts?

A: Selection criteria include component availability, procurement lead times, existing supplier relationships, and inventory management. Both parts are electrically and mechanically equivalent for the specified application parameters.
