Sensata-Crydom D1202 Solid State Relay SPST-NO — Equivalent & Substitute Parts

Part Overview

The Sensata-Crydom D1202 is a solid state relay (SSR) with SPST-NO (1 Form A) configuration, rated for 2A load current at 24–140V AC output. This component operates with 3–32VDC input and features zero-cross switching for AC loads. The D1202 is classified as obsolete, making identification of equivalent and substitute parts necessary for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the D1202 is determined by the following critical parameters:

• Circuit Configuration: All substitutes must maintain SPST-NO (1 Form A) topology
• Output Type: All substitutes must support AC output with zero-cross switching
• Input Voltage Range: All substitutes must accept 3–32VDC input
• Load Voltage Range: Substitutes must support minimum 24–140V; higher voltage ratings are acceptable
• Load Current Capacity: Substitutes must equal or exceed 2A rating
• Mounting and Termination: All substitutes must use chassis mount with screw terminal configuration
• Package Form Factor: All substitutes must use hockey puck package

The substitute parts listed below meet these criteria while offering improved product status (active vs. obsolete) and enhanced compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

D1210 (Sensata-Crydom)

The D1210 is the direct manufacturer equivalent within the Sensata-Crydom product line. It maintains identical input/output voltage ranges and circuit configuration as the D1202 while providing 10A load current capacity. The D1210 carries active product status, ROHS3 compliance, and REACH affected designation, making it suitable for new designs and ongoing production applications.

84134000 (Sensata-Crydom)

The 84134000 extends the load voltage range to 24–280V while maintaining 10A current capacity. This part is manufacturer-recommended and offers active product status with ROHS3 compliance. The expanded voltage rating provides additional design flexibility for applications requiring higher load voltages.

SSR-240D25 (TE Connectivity Potter & Brumfield)

The SSR-240D25 represents a cross-manufacturer substitute from TE Connectivity. It provides the highest load current capacity (25A) and extended voltage range (24–280V). This part is active, ROHS3 compliant, and REACH affected. Selection of this part is appropriate when higher current capacity or voltage margin is required.

All three substitute parts maintain the critical SPST-NO circuit topology, AC zero-cross output type, 3–32VDC input range, chassis mount configuration, screw terminal termination, and hockey puck package form factor required for D1202 replacement.

Frequently Asked Questions (FAQ)

Q: Can the D1210 directly replace the D1202 in existing applications?

A: Yes. The D1210 maintains identical input voltage (3–32VDC), output voltage range (24–140V), circuit configuration (SPST-NO), output type (AC zero-cross), mounting type (chassis mount), termination style (screw terminal), and package form factor (hockey puck). The increased load current rating (10A vs. 2A) does not affect compatibility.

Q: What is the difference between the D1210 and 84134000?

A: Both parts are Sensata-Crydom products with identical input voltage, circuit configuration, and load current (10A). The 84134000 extends the maximum load voltage to 280V compared to the D1210's 140V limit. Selection depends on application voltage requirements.

Q: When should the SSR-240D25 be selected over Sensata-Crydom alternatives?

A: The SSR-240D25 provides 25A load current capacity and 24–280V voltage range. Selection is appropriate when applications require higher current handling or extended voltage margin. This part is from TE Connectivity Potter & Brumfield and maintains all required electrical and mechanical parameters for D1202 substitution.

Q: Are all substitute parts available in the same hockey puck package?

A: Yes. All substitute parts (D1210, 84134000, SSR-240D25) use the hockey puck package form factor with chassis mount configuration and screw terminal termination, ensuring mechanical compatibility with D1202 mounting and connection requirements.

Q: What compliance certifications apply to these substitutes?

A: All substitute parts are ROHS3 compliant. The D1210 and 84134000 are REACH affected; the SSR-240D25 is also REACH affected. The original D1202 is REACH unaffected. Compliance requirements for your application determine which part is appropriate.
