D1210T Solid State Relay - Equivalent & Substitute Parts

Part Overview

The D1210T is a Solid State Relay (SSR) manufactured by Sensata-Crydom, configured as a SPST-NO (Single Pole Single Throw - Normally Open) relay with a hockey puck form factor. This component is designed for AC load switching applications with zero-cross detection capability. The part is currently in active production status with 877 units available in inventory. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when application requirements permit expanded parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the D1210T is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain identical switching topology
• Output Type: Must be AC with Zero Cross detection to preserve load switching characteristics
• Load Current: Must be rated for 10 A minimum to handle specified load requirements
• Mounting Type: Must be Chassis Mount to ensure mechanical compatibility
• Termination Style: Must be Screw Terminal for connection compatibility
• Package / Case: Must be Hockey Puck form factor for physical fit
• Load Voltage Range: Substitute must encompass or exceed the 24 V ~ 140 V range of the primary part
• Input Voltage Range: Substitute must accommodate the 3 ~ 32 VDC control signal range

The identified substitute part meets all mandatory compatibility criteria while offering an extended load voltage range, providing broader application flexibility.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 84137000N (part number 84137000N) qualifies as a direct substitute for the D1210T based on matching circuit topology, output characteristics, current rating, and physical form factor. Both parts are RoHS compliant and maintain active product status.

The primary difference is the input voltage minimum specification: the D1210T accepts control signals from 3 VDC, while the 84137000N requires a minimum of 4 VDC. Applications operating at exactly 3 VDC input must use the D1210T. For applications within the 4 ~ 32 VDC input range, the 84137000N is functionally equivalent.

The 84137000N provides an extended load voltage capability (24 V ~ 280 V versus 24 V ~ 140 V), which may be advantageous for applications requiring higher voltage switching margins or future design flexibility.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 84137000N replace the Sensata-Crydom D1210T in all applications?

A: The 84137000N is compatible with applications where the control input voltage is 4 VDC or higher. If your circuit requires 3 VDC input operation, the D1210T must be used. For all other specifications (load current, voltage range, circuit type, and physical form factor), the parts are interchangeable.

Q: What is the significance of the extended load voltage range on the 84137000N?

A: The 84137000N supports load voltages up to 280 V, compared to the D1210T's 140 V maximum. This extended range does not affect compatibility with the D1210T's 24 V ~ 140 V load specification but provides additional design margin and may support higher-voltage applications without component substitution.

Q: Are both parts suitable for the same mounting and termination requirements?

A: Yes. Both the D1210T and 84137000N feature identical Chassis Mount mounting type and Screw Terminal termination style, ensuring mechanical and electrical connection compatibility.

Q: What compliance certifications apply to both parts?

A: Both parts are RoHS compliant. The 84137000N additionally carries REACH Unaffected status. Both are classified under ECCN EAR99 for export control purposes.

Q: Does the hockey puck package form factor differ between these parts?

A: No. Both parts use the hockey puck package / case form factor, ensuring identical physical fit and mounting compatibility.
