D24110 Solid State Relay SPST-NO 110A 24-280V

Part Overview

The D24110 is an active solid state relay (SSR) manufactured by Sensata-Crydom, designed for industrial switching applications requiring high current capacity and wide voltage range compatibility. This SPST-NO (1 Form A) relay operates with AC zero-cross output, making it suitable for resistive and inductive load switching in control systems. The part is available in bulk packaging with 975 units in current inventory.

Alternative models may be required due to application-specific voltage requirements, load current specifications, or regional compliance considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the D24110 is determined by the following critical parameters:

Circuit Configuration: Both the main part and substitute must maintain SPST-NO (1 Form A) topology to ensure functional equivalence in single-pole switching applications.

Output Type: AC zero-cross operation is required to maintain compatibility with standard industrial control circuits and load types.

Mounting and Termination: Chassis mount configuration with screw terminal termination ensures mechanical and electrical interface compatibility.

Package Type: Hockey Puck form factor is mandatory for physical fit within existing enclosures and thermal management requirements.

Voltage and Current Ratings: Substitute parts must support the required input voltage range (minimum 3 ~ 32 VDC) and load voltage range (minimum 24 V ~ 280 V). Load current capacity must meet or exceed 110 A.

Compliance: RoHS and REACH compliance status must be verified for regulatory requirements in target markets.

Parameter Comparison

Engineering Selection Recommendations

The 84137180N (Crouzet) qualifies as a functional substitute for the D24110 based on matching circuit topology, output type, mounting configuration, and termination style. The substitute part provides higher load current capacity (125 A versus 110 A) and extended load voltage range (48 V ~ 660 V versus 24 V ~ 280 V), making it suitable for applications requiring greater voltage headroom or current margin.

The input voltage range of the 84137180N (4 ~ 32 VDC) is compatible with the D24110 specification (3 ~ 32 VDC) for most control circuit applications. The substitute part maintains RoHS compliance and offers REACH Unaffected status, which may provide regulatory advantages in certain markets.

Both parts are active products with established supply chains and are available in standard packaging configurations.

Frequently Asked Questions (FAQ)

Q: Can the 84137180N replace the D24110 in existing applications?

A: Yes, provided the application load voltage does not fall below 48 V (the minimum for the 84137180N). The D24110 supports loads as low as 24 V, while the 84137180N minimum is 48 V. If your application operates at 24-47 V, the substitute is not compatible.

Q: What is the significance of the higher current rating on the 84137180N?

A: The 84137180N is rated for 125 A compared to the D24110's 110 A. This provides additional current margin and thermal headroom for the same load, potentially extending component life in high-current applications.

Q: Are there differences in input voltage compatibility?

A: The D24110 accepts input voltage from 3 VDC, while the 84137180N minimum is 4 VDC. For control circuits operating below 4 VDC, the D24110 is required. Standard industrial control circuits typically operate at 12 VDC or 24 VDC, making both parts compatible in these applications.

Q: How do RoHS and REACH compliance differences affect selection?

A: Both parts meet RoHS requirements. The 84137180N carries REACH Unaffected status, indicating it does not contain substances of very high concern (SVHC) listed under REACH regulations. The D24110 is REACH Affected, meaning it may contain listed substances. Selection depends on regulatory requirements in your target market.

Q: Is the Hockey Puck package identical between both parts?

A: Both parts use Hockey Puck form factor with chassis mount configuration and screw terminal termination, ensuring mechanical and thermal interface compatibility in standard industrial enclosures.
