Sensata-Crydom D1202-10 Solid State Relay SPST-NO Equivalent & Substitute Parts

Part Overview

The Sensata-Crydom D1202-10 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 features a hockey puck form factor with screw terminal connections and operates from 3–32VDC input. The D1202-10 is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the D1202-10 is determined by the following critical parameters: circuit configuration (SPST-NO), output type (AC), input voltage range (3–32VDC), mounting type (chassis mount), termination style (screw terminal), and package form factor (hockey puck). Load current and maximum load voltage are secondary parameters that define substitution capability.

The D1202-10 operates at 2A maximum load current. Substitute parts with equal or higher current ratings (10A, 25A) are electrically compatible for applications requiring 2A or less. Load voltage compatibility requires that the substitute part's maximum voltage rating meets or exceeds the application requirement within the 24–140V range.

Three substitute parts are identified:

D1210-10 (Sensata-Crydom): Direct manufacturer upgrade within the same series. Maintains all primary parameters with increased load current (10A) and identical load voltage range (24–140V). Active product status.

84134200 (Sensata-Crydom GN Series): Manufacturer-recommended substitute. Maintains all primary parameters with increased load current (10A) and extended load voltage range (24–280V). Active product status with RoHS compliance.

SSR-240D25R (TE Connectivity Potter & Brumfield): Cross-manufacturer substitute. Maintains all primary parameters with increased load current (25A) and extended load voltage range (24–280V). Active product status.

Parameter Comparison

Engineering Selection Recommendations

D1210-10 is the primary substitute for direct replacement within the Sensata-Crydom product line. It maintains identical electrical specifications while offering increased load current capacity and active product status. This part is suitable for applications where the original 2A rating is sufficient and load voltage does not exceed 140V.

84134200 is the manufacturer-recommended substitute when extended load voltage capability (up to 280V) is required. This part provides increased current capacity (10A) and RoHS compliance, making it suitable for modern design requirements and regulatory compliance scenarios.

SSR-240D25R is the cross-manufacturer substitute for applications requiring maximum current capacity (25A) and extended voltage range (24–280V). Selection of this part introduces a different manufacturer (TE Connectivity Potter & Brumfield) and should be evaluated based on supply chain and qualification requirements specific to the application.

All three substitutes are electrically compatible with the D1202-10 for applications operating at or below 2A load current and within the specified voltage ranges.

Frequently Asked Questions (FAQ)

Q: Can the D1210-10 directly replace the D1202-10?

A: Yes. The D1210-10 maintains identical input voltage, output voltage range, circuit configuration, mounting type, termination style, and package form factor. The increased load current rating (10A versus 2A) does not affect compatibility for applications requiring 2A or less.

Q: What is the difference between D1210-10 and 84134200?

A: Both parts are Sensata-Crydom products with identical input voltage and load current ratings (10A). The 84134200 extends the maximum load voltage to 280V (compared to 140V for D1210-10) and includes RoHS compliance certification. Selection depends on whether the application requires voltage operation above 140V.

Q: Can SSR-240D25R be used in place of the D1202-10?

A: Yes, for applications operating at 2A or less. The SSR-240D25R maintains all primary electrical and mechanical parameters. The higher current rating (25A) and extended voltage range (24–280V) provide additional operational margin. This part is manufactured by TE Connectivity Potter & Brumfield rather than Sensata-Crydom.

Q: Are all substitutes compatible with screw terminal connections?

A: Yes. All substitute parts use screw terminal termination style, matching the D1202-10 connection method.

Q: What is the significance of the hockey puck package form factor?

A: The hockey puck form factor is a standardized solid state relay package with specific mechanical dimensions and mounting interface. All listed substitutes use this identical package, ensuring mechanical compatibility with existing mounting hardware and thermal management solutions.

Q: Does load current rating affect substitution compatibility?

A: Load current rating determines the maximum current the relay can safely switch. A substitute with a higher rating (10A or 25A) can safely operate at the original part's current requirement (2A). A substitute with a lower rating would not be compatible.

Q: Are there compliance differences between the substitute parts?

A: Yes. The D1202-10 is REACH Unaffected. The D1210-10 is REACH Affected and RoHS3 Compliant. The 84134200 is RoHS Compliant and MSL 1 (Unlimited). The SSR-240D25R is REACH Affected and RoHS non-compliant. Application requirements and regulatory jurisdiction determine which compliance profile is necessary.
