CSW2450G Solid State Relay - Equivalent & Substitute Parts

Part Overview

The CSW2450G is a solid state relay (SSR) manufactured by Sensata-Crydom, configured as a SPST-NO (Single Pole Single Throw - Normally Open) device with a 50A load capacity and operating voltage range of 24V to 280V AC. The device features a hockey puck form factor with screw terminal connections and zero-cross switching capability for AC loads. Currently designated as Last Time Buy, alternative equivalent parts are available to ensure supply continuity and design flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSW2450G is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A)
• Load Current Rating: Must be 50 A minimum
• Package Form Factor: Must be Hockey Puck
• Termination Style: Must be Screw Terminal
• Mounting Type: Must be Chassis Mount
• Output Type: Must be AC with Zero Cross switching

Two substitute parts meet these criteria:

D2450G (Sensata-Crydom): Direct functional equivalent with identical electrical specifications and form factor. Differs in product status (Active vs. Last Time Buy) and RoHS compliance generation (ROHS3 vs. RoHS Compliant).

84137460N (Crouzet): Functionally equivalent with identical circuit configuration, current rating, and form factor. Load voltage range extends to 660V (vs. 280V maximum for CSW2450G), providing broader application capability while maintaining all other critical parameters.

Parameter Comparison

Engineering Selection Recommendations

D2450G is the primary substitute for CSW2450G applications. Both parts are manufactured by Sensata-Crydom with identical electrical and mechanical specifications. D2450G carries Active product status, ensuring long-term availability and supply stability. The upgrade to ROHS3 compliance and REACH Affected designation reflects current regulatory standards. This part is suitable for direct replacement in all CSW2450G applications without design modification.

84137460N serves as an alternative substitute when extended load voltage capability is required. Manufactured by Crouzet, this part maintains all critical functional parameters while supporting load voltages up to 660V, compared to the 280V maximum of CSW2450G. The input voltage range minimum increases from 3V to 4V, which may require verification in low-voltage control circuits. This part is appropriate for applications requiring higher voltage switching capability within the 50A current class.

Both substitute parts carry Active product status and current compliance certifications, ensuring availability and regulatory alignment for new designs and production continuity.

Frequently Asked Questions (FAQ)

Q: Can D2450G replace CSW2450G in existing designs without modification?

A: Yes. D2450G is functionally and mechanically identical to CSW2450G. All electrical parameters, form factor, and termination specifications match exactly. No circuit or mechanical redesign is required.

Q: What is the primary difference between D2450G and 84137460N?

A: Both parts are functionally equivalent for the CSW2450G application. The key difference is load voltage range: D2450G supports 24V to 280V, while 84137460N supports 48V to 660V. The 84137460N also has a minimum input voltage of 4V instead of 3V. Select 84137460N only if your application requires the extended voltage capability.

Q: Why does CSW2450G have Last Time Buy status?

A: Last Time Buy status indicates the manufacturer is discontinuing this part number. D2450G and 84137460N are available alternatives with Active status, ensuring continued supply for new and replacement applications.

Q: Are all three parts RoHS compliant?

A: Yes. CSW2450G and 84137460N are RoHS Compliant. D2450G is ROHS3 Compliant, which represents a more recent compliance standard. All three parts meet RoHS requirements.

Q: Does packaging type affect substitution?

A: Packaging type (Bulk vs. Box) does not affect electrical or mechanical compatibility. CSW2450G and D2450G are supplied in Bulk packaging, while 84137460N is supplied in Box packaging. Select based on your procurement and inventory requirements.

Q: Can 84137460N be used in applications designed for CSW2450G?

A: Yes, provided your application load voltage does not exceed 280V. The 84137460N's extended voltage range (up to 660V) makes it suitable for CSW2450G applications. However, verify that the minimum input voltage of 4V (vs. 3V for CSW2450G) is compatible with your control circuit.
