Sensata-Crydom A1202 SSR Relay SPST-NO 2A 24-140V Equivalent & Substitute Parts

Part Overview

The Sensata-Crydom A1202 is a solid state relay (SSR) with SPST-NO (1 Form A) configuration, rated for 2A load current at 24-140V output voltage. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new designs. The A1202 operates with AC zero-cross output switching and accepts 90-280VAC input voltage, utilizing screw terminal connections in a hockey puck package format.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the A1202 is determined by the following critical parameters: circuit configuration (SPST-NO), output type (AC zero-cross), input voltage range (90-280VAC), mounting type (chassis mount), termination style (screw terminal), and package format (hockey puck). Load current and output voltage range define the substitution hierarchy.

The A1202 operates at 2A maximum load current with a 24-140V output range. Substitute parts must maintain SPST-NO functionality and zero-cross AC switching. Parts with higher current ratings (10A, 25A) are forward-compatible substitutes when the application load does not exceed their specifications. Parts with extended voltage ranges (24-280V) provide broader operational flexibility while maintaining the same input voltage tolerance.

Parameter Comparison

Engineering Selection Recommendations

A1210 (Sensata Technologies): Direct functional equivalent with 10A current rating. Maintains identical input/output voltage specifications and package format. Product status is active with ROHS3 compliance. Suitable for applications where the load current does not exceed 2A and the 24-140V output range is sufficient.

84134001 (Sensata Technologies, Series GN): Manufacturer-recommended substitute with extended output voltage range (24-280V). Rated for 10A load current. Product status is active with RoHS compliance. Provides broader voltage flexibility while maintaining Sensata Technologies manufacturing continuity. Moisture sensitivity level rated at 1 (unlimited).

SSR-240A25 (TE Connectivity Potter & Brumfield Relays, Series SSR): Highest current-rated substitute at 25A with extended output voltage range (24-280V). Product status is active. Suitable for applications requiring higher current capacity or extended voltage operation. RoHS non-compliant status requires verification against system requirements.

Frequently Asked Questions (FAQ)

Q: Can the A1210 directly replace the A1202 in all applications? A: The A1210 maintains identical circuit configuration, input/output voltage specifications, and package format. It is a direct functional substitute for applications where load current does not exceed 2A. The higher 10A rating provides design margin without affecting compatibility.

Q: What is the primary difference between A1210 and 84134001? A: Both are 10A-rated Sensata Technologies SSR relays with identical input voltage (90-280VAC). The 84134001 extends the output voltage range to 24-280V compared to the A1210's 24-140V range. Select 84134001 when higher output voltage operation is required.

Q: Is SSR-240A25 compatible with the A1202 application? A: SSR-240A25 maintains all critical parameters: SPST-NO configuration, AC zero-cross output, 90-280VAC input, screw terminal connections, and hockey puck package. The 25A current rating and 24-280V output range provide enhanced capability. Verify RoHS compliance requirements before selection, as this part is RoHS non-compliant.

Q: What packaging formats are available for these substitutes? A: All substitute parts (A1210, 84134001, SSR-240A25) are supplied in hockey puck package format with screw terminal connections, maintaining mechanical and electrical interface compatibility with the A1202.

Q: Are there compliance differences between substitute options? A: A1210 is ROHS3 compliant. 84134001 is RoHS compliant. SSR-240A25 is RoHS non-compliant. System compliance requirements determine the appropriate selection.
