D1210-10 Solid State Relay SPST-NO 10A 24-140V

Part Overview

The D1210-10 is a solid state relay (SSR) manufactured by Sensata-Crydom, configured as a single-pole single-throw normally open (SPST-NO) device with a 10A load current rating. The unit operates with a 24V to 140V AC load voltage range and accepts 3V to 32V DC input control signals. It features a hockey puck form factor with screw terminal connections and is mounted as a chassis component. The product maintains active status and is RoHS3 compliant.

Equivalent and substitute parts are identified when they maintain functional compatibility across critical electrical parameters while accommodating application-specific requirements such as higher load voltage ranges or increased current capacity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the D1210-10 is determined by the following critical parameters:

Circuit Configuration: All substitute parts must maintain SPST-NO (1 Form A) topology to ensure functional equivalence in switching applications.

Output Type: AC output capability is required for compatibility with the original application.

Input Voltage Range: Substitute parts must accept the 3V to 32VDC control signal range or a compatible subset thereof.

Mounting and Termination: Chassis mount configuration with screw terminal connections must be preserved.

Package Form Factor: Hockey puck package is the standard form factor for this product category.

Load Voltage and Current: Substitute parts may exceed the original 24V–140V load voltage range and 10A current rating, as higher specifications provide backward compatibility. Parts with lower specifications are not suitable.

Three substitute parts meet these criteria:

• 84134200 (Sensata-Crydom): Extends load voltage to 280V while maintaining 10A current and SPST-NO configuration.
• 84137210N (Crouzet): Increases load current to 25A and extends load voltage to 280V; represents an upgraded specification.
• ASR-SI240D10R-LR (Altran Magnetics, LLC): Maintains 10A current while extending load voltage to 48V–280V range.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain active product status and meet RoHS compliance requirements, ensuring regulatory alignment with the original D1210-10.

84134200 is a direct manufacturer equivalent from Sensata-Crydom with identical input voltage range (3–32VDC) and load current (10A). The extended load voltage specification (24V–280V) provides operational compatibility for applications requiring higher load voltages while maintaining the same current capacity.

84137210N from Crouzet offers increased load current capacity (25A) and extended load voltage range (24V–280V). This part is suitable for applications where the original 10A specification is insufficient, provided the input voltage range (4–32VDC) is compatible with the control circuit.

ASR-SI240D10R-LR from Altran Magnetics, LLC maintains the 10A load current specification with an extended load voltage range (48V–280V). The minimum load voltage of 48V differs from the original 24V specification; this part is suitable only for applications where the load voltage does not fall below 48V.

Frequently Asked Questions (FAQ)

Q: Can the 84134200 be used as a direct replacement for the D1210-10?

A: Yes. The 84134200 maintains identical input voltage range, load current, and circuit configuration. The extended load voltage range (280V maximum) provides backward compatibility for the original 24V–140V specification.

Q: What is the primary difference between the 84137210N and the D1210-10?

A: The 84137210N increases load current capacity from 10A to 25A and extends maximum load voltage from 140V to 280V. The input voltage range shifts from 3–32VDC to 4–32VDC. Select this part only if the application requires higher current capacity.

Q: Is the ASR-SI240D10R-LR compatible with applications using 24V load voltage?

A: No. The ASR-SI240D10R-LR specifies a minimum load voltage of 48V. Applications requiring 24V load voltage operation must use the D1210-10, 84134200, or 84137210N.

Q: Do all substitute parts use the same hockey puck package?

A: Yes. All substitute parts maintain the hockey puck form factor with screw terminal connections, ensuring mechanical and electrical compatibility with existing mounting hardware.

Q: Are there compliance differences between the substitute parts?

A: All parts are RoHS compliant. The D1210-10 and ASR-SI240D10R-LR are RoHS3 compliant. The 84134200 and 84137210N are RoHS compliant. Both compliance levels are acceptable for regulatory purposes.
