D1202-B Equivalent & Substitute Parts

Part Overview

The D1202-B is a solid-state relay (SSR) manufactured by Sensata-Crydom, configured as a SPST-NC (1 Form B) device in a hockey puck package. This component is designed for AC load switching applications with zero-cross detection, operating with a 3–32VDC input and supporting loads from 24V to 140V at 2A capacity. The D1202-B is classified as obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new design implementations.

Substitute Part Grouping Explanation

The D1210-B qualifies as a direct substitute for the D1202-B based on the following critical parameters:

• Circuit Configuration: Both devices are SPST-NC (1 Form B) solid-state relays
• Output Type: Both feature AC output with zero-cross detection
• Input Voltage Range: Both accept 3 ~ 32VDC control input
• Load Voltage Range: Both support 24 V ~ 140 V AC loads
• Mounting Type: Both are chassis-mount devices
• Termination Style: Both use screw terminals
• Package / Case: Both are housed in hockey puck packages
• Manufacturer: Both are manufactured by Sensata-Crydom within the same product series

The primary difference between these devices is load current capacity: the D1202-B is rated for 2A, while the D1210-B is rated for 10A. This difference allows the D1210-B to serve as a substitute in applications where the D1202-B's 2A rating is insufficient or where higher current capacity is required for future design flexibility.

Engineering Selection Recommendations

The D1210-B is the appropriate substitute for the D1202-B in applications requiring SPST-NC solid-state relay functionality. The D1210-B offers the following advantages:

• Active Product Status: The D1210-B is an active product, ensuring long-term availability and continued manufacturer support, whereas the D1202-B is obsolete.
• Regulatory Compliance: The D1210-B is ROHS3 compliant, meeting current environmental and regulatory requirements for electronic components.
• Current Capacity: The D1210-B's 10A rating provides increased headroom over the D1202-B's 2A rating, accommodating higher load currents or providing design margin for future modifications.
• Identical Electrical Interface: Both devices share identical input voltage, load voltage, circuit configuration, and output characteristics, ensuring direct functional compatibility.

Selection of the D1210-B eliminates obsolescence risk and ensures compliance with current regulatory standards while maintaining electrical and mechanical compatibility with existing designs.

Frequently Asked Questions (FAQ)

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

A: Yes. Both devices share identical circuit configuration (SPST-NC), input voltage range (3–32VDC), load voltage range (24–140V), output type (AC, zero-cross), mounting type (chassis mount), termination style (screw terminal), and package type (hockey puck). The D1210-B's higher current rating (10A vs. 2A) does not prevent direct substitution.

Q: What is the primary difference between these two parts?

A: The D1210-B is rated for 10A load current, while the D1202-B is rated for 2A. All other electrical and mechanical parameters are identical.

Q: Why should I use the D1210-B instead of the D1202-B?

A: The D1202-B is obsolete, while the D1210-B is an active product with guaranteed availability. The D1210-B also meets ROHS3 compliance requirements.

Q: Are there any mechanical compatibility concerns when substituting the D1210-B for the D1202-B?

A: No. Both devices use identical hockey puck packaging, chassis-mount configuration, and screw terminal termination, ensuring mechanical compatibility in existing installations.

Q: Does the D1210-B's higher current rating affect circuit design?

A: No. The higher current rating of the D1210-B does not require circuit modifications. It provides additional capacity and design margin without affecting control input requirements or load voltage specifications.

Q: What regulatory certifications apply to the D1210-B?

A: The D1210-B is ROHS3 compliant and REACH affected. The D1202-B is REACH unaffected. Both are classified under ECCN EAR99.
