Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSW2450-10 is determined by the following critical parameters:

Primary Substitution Criteria:

• Circuit configuration: SPST-NO (1 Form A)
• Output type: AC
• Load current rating: 50 A minimum
• Package form factor: Hockey Puck
• Termination style: Screw Terminal
• Mounting type: Chassis Mount

Secondary Compatibility Factors:

• Input voltage range: Must accommodate 3 ~ 32VDC control signal
• Load voltage range: Must support minimum 24 V ~ 280 V operation
• Physical and electrical interface compatibility

The identified substitutes meet these core electrical and mechanical requirements, enabling direct functional replacement in applications designed for the CSW2450-10.

Engineering Selection Recommendations

D2450-10 (Direct Substitute - Recommended Primary Choice)

The D2450-10 is the optimal replacement for the obsolete CSW2450-10. Both parts are manufactured by Sensata-Crydom and share identical electrical specifications: 3-32VDC input, 24-280V load voltage, and 50A current rating. The D2450-10 maintains active product status with significantly higher inventory availability (20,199 units in stock versus 1,065 for the CSW2450-10). Both components are ROHS3 compliant and carry identical ECCN and HTSUS classifications. The D2450-10 features improved moisture sensitivity rating (MSL 1 Unlimited) compared to the CSW2450-10 (Not Applicable).

84137320N (MFR Recommended Alternative)

The Crouzet 84137320N serves as a manufacturer-recommended alternative when D2450-10 availability is constrained. This part maintains the same circuit configuration, output type, load current, and physical form factor. The 84137320N accommodates a higher load voltage range (48-660V) and slightly elevated input voltage floor (4VDC minimum), making it suitable for applications operating within the CSW2450-10's original 24-280V specification. The part is RoHS compliant and carries active product status with 933 units in stock. Note that REACH status differs (REACH Unaffected versus REACH Affected for the CSW2450-10 and D2450-10).

Frequently Asked Questions (FAQ)

Q: Can the D2450-10 be used as a direct replacement for the CSW2450-10?

A: Yes. The D2450-10 is a direct functional equivalent with identical electrical ratings (3-32VDC input, 24-280V load, 50A), matching circuit configuration (SPST-NO), and identical physical form factor (hockey puck, screw terminal, chassis mount). Both are Sensata-Crydom products with equivalent compliance certifications.

Q: What are the key differences between D2450-10 and 84137320N?

A: Both parts share the same circuit configuration, output type, load current, and package form factor. The primary differences are manufacturer (Sensata-Crydom versus Crouzet), load voltage range (24-280V versus 48-660V), input voltage minimum (3VDC versus 4VDC), and REACH compliance status. The 84137320N's higher voltage rating makes it suitable for applications within the original specification range.

Q: Are there packaging differences between these substitutes?

A: The CSW2450-10 and D2450-10 are supplied in bulk packaging. The 84137320N is supplied in box packaging. All three maintain identical hockey puck form factor and screw terminal configuration for mechanical compatibility.

Q: Which substitute should be selected for new designs?

A: The D2450-10 is the recommended choice for new designs due to active product status, superior inventory availability, and identical electrical specifications to the original CSW2450-10. The 84137320N serves as a secondary option when D2450-10 supply is unavailable.

Q: Are compliance certifications equivalent across all three parts?

A: All three parts are RoHS compliant. The CSW2450-10 and D2450-10 are ROHS3 compliant with identical ECCN (EAR99) and HTSUS (8536.49.0080) classifications. The 84137320N is RoHS compliant with different HTSUS classification (8536.41.0060) and REACH status (REACH Unaffected).
