Sensata-Crydom 4D1210 SSR Relay: Equivalent & Substitute Parts

Part Overview

The Sensata-Crydom 4D1210 is a solid-state relay (SSR) with SPST-NO (1 Form A) configuration, rated for 10A load current and 24–140V AC output with zero-cross switching. This component is classified as obsolete, necessitating identification of active equivalent models for continued system support and procurement. Direct substitutes maintain identical electrical and mechanical specifications while offering current product status and improved compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4D1210 is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A)
• Output Type: Must be AC with zero-cross switching
• Input Voltage Range: Must support 3 ~ 32VDC
• Load Current Rating: Must be rated for 10 A minimum
• Load Voltage Range: Must support minimum 24 V ~ 140 V
• Mounting Type: Must be Chassis Mount
• Termination Style: Must be Screw Terminal
• Package / Case: Must be Hockey Puck form factor

The 4D1210 has two direct substitutes from Sensata-Crydom: the D1210 and D2410. The D1210 maintains identical electrical and mechanical specifications with active product status. The D2410 provides extended load voltage capability (24 V ~ 280 V) while maintaining all other critical parameters, offering enhanced voltage headroom for applications requiring higher load voltage tolerance.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: D1210

The D1210 is the direct functional equivalent of the 4D1210, providing identical electrical performance and mechanical compatibility. The D1210 carries active product status with ROHS3 compliance and REACH documentation, ensuring long-term availability and regulatory alignment. This part is recommended for applications requiring exact parameter matching to the original 4D1210 specification.

Extended Voltage Alternative: D2410

The D2410 maintains all critical electrical and mechanical parameters while extending the load voltage range to 24 V ~ 280 V. This part is suitable for applications where the original 24 V ~ 140 V load voltage specification is insufficient, provided the 10A current rating and zero-cross AC switching characteristics remain appropriate. The D2410 also carries active product status with ROHS3 compliance and REACH documentation.

Both D1210 and D2410 are manufactured by Sensata-Crydom and maintain the same Series 1 designation, Chassis Mount configuration, Screw Terminal termination, and Hockey Puck package form factor as the obsolete 4D1210.

Frequently Asked Questions (FAQ)

Q: Can the D1210 be used as a direct replacement for the 4D1210?

A: Yes. The D1210 maintains identical electrical specifications (3 ~ 32VDC input, 24 V ~ 140 V load voltage, 10A current rating, AC zero-cross output) and mechanical configuration (Chassis Mount, Screw Terminal, Hockey Puck package). The primary difference is product status (Active vs. Obsolete) and enhanced compliance certifications (ROHS3 and REACH documentation).

Q: What is the difference between the D1210 and D2410?

A: Both parts share identical input voltage, current rating, circuit configuration, and mechanical specifications. The D2410 extends the load voltage range from 24 V ~ 140 V to 24 V ~ 280 V, providing higher voltage tolerance for applications requiring extended load voltage capability.

Q: Are the D1210 and D2410 pin-compatible with the 4D1210?

A: Yes. All three parts use identical Screw Terminal termination and Hockey Puck package form factor, ensuring mechanical and electrical compatibility in Chassis Mount applications.

Q: What compliance certifications apply to the substitute parts?

A: Both D1210 and D2410 are ROHS3 compliant and REACH affected. The original 4D1210 is RoHS compliant. Verify compliance requirements for your specific application and regulatory jurisdiction.

Q: Should I select D1210 or D2410 for a new design?

A: Select D1210 if your application load voltage does not exceed 140V. Select D2410 if your application requires load voltage capability up to 280V. Both parts are active products with current availability and compliance documentation.
