D2410K Solid State Relay - Equivalent & Substitute Parts

Part Overview

The D2410K is an active Sensata-Crydom solid state relay (SSR) featuring SPST-NO (1 Form A) switching configuration in a hockey puck package. This component provides AC output with zero-cross switching capability, designed for chassis mount applications requiring 10A load current handling across 24V to 280V operating ranges. The part is ROHS3 compliant and REACH affected, with unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, application redesign, or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

The ASR-SI240D10Z-LRQ qualifies as a substitute for the D2410K based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Circuit configuration: SPST-NO (1 Form A)
• Output type: AC, Zero Cross
• Load current: 10 A
• Package type: Hockey Puck
• Mounting type: Chassis Mount
• Termination style: Screw Terminal
• RoHS compliance: ROHS3 Compliant

Allowable Parameter Variations:

• Input voltage range: ASR-SI240D10Z-LRQ operates 4 ~ 32 VDC (versus D2410K at 3 ~ 32 VDC). The substitute maintains the upper limit and raises the minimum by 1V, remaining within typical control circuit specifications.
• Load voltage range: ASR-SI240D10Z-LRQ operates 48 V ~ 280 V (versus D2410K at 24 V ~ 280 V). The substitute maintains the upper limit and raises the minimum to 48V, suitable for applications not requiring sub-48V load operation.

Parameter Comparison

Engineering Selection Recommendations

Both the D2410K and ASR-SI240D10Z-LRQ maintain active product status and ROHS3 compliance, ensuring continued manufacturer support and regulatory alignment. Selection between these parts depends on application-specific load voltage requirements. The D2410K supports load voltages down to 24V, making it suitable for lower-voltage AC applications. The ASR-SI240D10Z-LRQ operates from 48V minimum load voltage, appropriate for applications within this range and above. Input voltage tolerance differences (3V minimum versus 4V minimum) are negligible for standard 24VDC control circuits. Both components feature identical switching characteristics, current capacity, and mechanical form factor, ensuring functional interchangeability within their respective voltage operating windows.

Frequently Asked Questions (FAQ)

Q: Can the ASR-SI240D10Z-LRQ directly replace the D2410K in all applications?

A: Direct substitution is valid only when the application load voltage operates at 48V or higher. Applications requiring load voltages between 24V and 48V require the D2410K specifically.

Q: Are the physical dimensions and mounting interfaces identical?

A: Yes. Both components use the hockey puck package with chassis mount configuration and screw terminal termination, ensuring mechanical compatibility in existing designs.

Q: What is the significance of the zero-cross output type?

A: Zero-cross switching synchronizes relay activation with AC voltage zero-crossing points, reducing electromagnetic interference and switching transients in AC load circuits.

Q: Do both parts meet the same regulatory requirements?

A: Both components are ROHS3 compliant and carry EAR99 ECCN classification. The D2410K is REACH affected, while the ASR-SI240D10Z-LRQ is REACH unaffected. Regulatory requirements for your specific application determine which status is applicable.

Q: What is the practical difference between 3V and 4V minimum input voltage?

A: Standard industrial 24VDC control circuits operate well above both thresholds. This 1V difference is not a practical constraint for typical applications.

Q: Can these relays be used interchangeably in new designs?

A: Selection should be based on the required load voltage range. For designs requiring 24V to 48V load operation, specify the D2410K. For designs operating at 48V and above, either part is suitable based on availability.
