Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMD2450-10 is determined by strict equivalence across the following electrical and mechanical parameters:

• Circuit configuration: SPST-NO (1 Form A)
• Output type: AC
• Input voltage range: 3 ~ 32VDC
• Load voltage range: 24 V ~ 280 V
• Load current rating: 50 A
• Mounting type: Chassis Mount
• Termination style: Screw Terminal
• Package type: Hockey Puck

All identified substitute parts maintain identical electrical specifications and mechanical form factor, ensuring direct functional replacement without circuit redesign or mechanical rework.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts (84137220 and CWD2450-10) are active products from Sensata-Crydom with identical electrical and mechanical specifications to the obsolete CMD2450-10. Selection between the two substitutes should be based on the following factors:

Part 84137220 (GN Series) carries ROHS3 compliance and REACH Affected status, with MSL rating of 1 (Unlimited), indicating suitability for applications requiring enhanced environmental compliance and moisture tolerance.

Part CWD2450-10 (CW24 Series) carries ROHS3 compliance and REACH Affected status, with MSL rating of Not Applicable, suitable for standard industrial applications where moisture sensitivity is not a design constraint.

Both parts are functionally interchangeable with the CMD2450-10 and support direct replacement without modification to circuit design or mechanical assembly.

Frequently Asked Questions (FAQ)

Q: Can the CMD2450-10 be directly replaced with either 84137220 or CWD2450-10?

A: Yes. Both substitute parts maintain identical electrical ratings (50A, 3-32VDC input, 24-280V AC output), circuit configuration (SPST-NO), and mechanical form factor (Hockey Puck, Chassis Mount, Screw Terminal). Direct substitution is supported without circuit or mechanical changes.

Q: What is the primary reason for identifying substitutes for the CMD2450-10?

A: The CMD2450-10 is classified as obsolete. The identified substitutes (84137220 and CWD2450-10) are active products, ensuring continued availability and manufacturer support for new designs and production requirements.

Q: Are there differences in compliance certifications between the substitutes?

A: Both substitutes carry ROHS3 compliance and REACH Affected status. The 84137220 specifies MSL 1 (Unlimited), while CWD2450-10 specifies MSL Not Applicable. Selection should align with application environmental requirements.

Q: Does the Hockey Puck package type remain consistent across all parts?

A: Yes. The CMD2450-10, 84137220, and CWD2450-10 all use the Hockey Puck package type with Chassis Mount configuration and Screw Terminal termination, ensuring mechanical compatibility in existing designs.

Q: What electrical parameters must remain constant for substitution eligibility?

A: Input voltage range (3-32VDC), load voltage range (24-280V AC), load current rating (50A), circuit configuration (SPST-NO), and output type (AC) must all remain identical. All identified substitutes meet these requirements.
