CMD24110 Solid State Relay SPST-NO 110A 24-280V Equivalent & Substitute Parts

Part Overview

The CMD24110 is a solid state relay (SSR) with SPST-NO (1 Form A) configuration, rated for 110A load current at 24-280V AC output. This component features a hockey puck form factor with screw terminal connections and zero-cross switching capability. The CMD24110 is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations. Substitute parts maintain the same electrical specifications and mechanical form factor while offering active product status and improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CMD24110 are grouped based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

• Circuit Configuration: All substitutes maintain SPST-NO (1 Form A) topology
• Load Voltage Range: All substitutes operate at 24 V ~ 280 V AC
• Input Voltage Range: All substitutes accept 3 ~ 32 VDC control input
• Output Type: All substitutes feature AC output with zero-cross switching
• Package Form Factor: All substitutes use hockey puck chassis mount configuration
• Termination: All substitutes use screw terminal connections

Substitutes are differentiated by load current rating (110A or 125A), manufacturer series designation, and product status. Parts rated at 125A (84137080, CWD24125) provide higher current capacity while maintaining full backward compatibility with 110A applications. The D24110 maintains identical 110A rating as the original CMD24110.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (110A Rating): The D24110 provides identical electrical specifications and current rating to the CMD24110 while maintaining active product status. This part is the preferred choice for applications requiring exact 110A performance specifications.

For Upgraded Capacity (125A Rating): Both 84137080 and CWD24125 offer 125A load current capacity, providing 13.6% additional headroom over the original 110A specification. These parts are suitable for applications where increased current margin is beneficial. The 84137080 is manufactured by Sensata Technologies under the GN series, while CWD24125 is manufactured by Sensata-Crydom under the CW24 series.

Compliance Considerations: All substitute parts maintain RoHS compliance. The CWD24125 and D24110 carry ROHS3 certification with REACH compliance status, representing the most current regulatory alignment. The 84137080 carries standard RoHS compliance with MSL rating of 1 (Unlimited).

Availability: All substitute parts are currently in active production with confirmed inventory availability, eliminating supply chain risk associated with the obsolete CMD24110.

Frequently Asked Questions (FAQ)

Q: Can the 125A-rated substitutes (84137080, CWD24125) be used in applications designed for the 110A CMD24110?

A: Yes. The 125A-rated parts are fully compatible with 110A applications. Higher current rating provides additional operational margin without affecting circuit performance or safety. All electrical parameters including voltage ranges, input control voltage, and switching characteristics remain identical.

Q: What is the difference between D24110 and the 125A substitutes?

A: The D24110 maintains the original 110A current rating, providing a direct specification match to CMD24110. The 84137080 and CWD24125 offer 125A capacity. Selection depends on whether exact current rating matching or increased capacity margin is required for the application.

Q: Are there mechanical compatibility concerns when substituting these parts?

A: No. All substitute parts use identical hockey puck form factor, chassis mount configuration, and screw terminal termination. Direct mechanical interchange is supported without modification to mounting hardware or electrical connections.

Q: How do the different manufacturer series (CMD24, GN, CW24, 1-110/125A) affect substitution?

A: Series designations reflect internal manufacturer product line organization but do not affect electrical or mechanical compatibility. All parts within this substitution group meet identical functional specifications for SPST-NO relay operation at the specified voltage and current ratings.

Q: What is the significance of ROHS3 compliance versus standard RoHS compliance?

A: ROHS3 represents the current regulatory standard with updated substance restrictions. Parts carrying ROHS3 certification (D24110, CWD24125) meet the latest environmental compliance requirements. Standard RoHS compliance (84137080) remains fully compliant but represents an earlier certification generation.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, within the electrical and mechanical parameters specified. All parts share identical control voltage input range (3-32VDC), load voltage range (24-280V AC), circuit configuration (SPST-NO), and switching characteristics (AC, zero-cross). No design modification is required for substitution.
