RAM1A23D25 Solid State Relay - Equivalent & Substitute Parts

Part Overview

The RAM1A23D25 is a solid state relay (SSR) manufactured by Carlo Gavazzi Inc., configured as a SPST-NO (Single Pole Single Throw - Normally Open) device in a hockey puck form factor. This relay is designed for AC load switching applications with zero-cross detection, operating with a 3-32VDC control input and supporting load voltages from 24V to 265V at 25A continuous current. The product is currently active in production with screw terminal connections suitable for chassis mount installations.

Equivalent and substitute parts are identified when they maintain the same functional circuit topology, load current rating, input voltage range, and physical package configuration, while operating within compatible load voltage specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RAM1A23D25 is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) topology
• Load Current Rating: Must be rated for 25 A continuous operation
• Control Input Voltage: Must accept 3 ~ 32VDC input range
• Output Type: Must feature AC switching with zero-cross detection
• Load Voltage Compatibility: Substitute must support the minimum 24V and accommodate the application's maximum voltage requirement
• Physical Package: Must be hockey puck form factor with screw terminal connections
• Mounting Configuration: Must support chassis mount installation

The identified substitute part maintains all critical electrical parameters and physical form factor requirements, with a load voltage specification that extends to 280V, providing enhanced voltage margin for the same 25A current rating.

Parameter Comparison

Engineering Selection Recommendations

Both the RAM1A23D25 and 84137010 are active production components suitable for direct substitution in SPST-NO AC relay applications requiring 25A switching capacity. The Sensata-Crydom 84137010 provides an extended load voltage specification (280V maximum versus 265V), offering additional operational margin in applications approaching the upper voltage limit.

The 84137010 carries RoHS3 compliance certification and REACH Affected status, whereas the RAM1A23D25 is REACH Unaffected. Selection between these parts should consider regulatory compliance requirements specific to the end application and geographic market.

Both components are classified under ECCN EAR99 for export control purposes and utilize screw terminal connections for field installation.

Frequently Asked Questions (FAQ)

Q: Can the 84137010 directly replace the RAM1A23D25 in existing applications?

A: Yes. Both relays maintain identical circuit topology (SPST-NO), control input voltage range (3-32VDC), load current rating (25A), output type (AC with zero-cross detection), and physical package configuration (hockey puck with screw terminals). The 84137010 supports a slightly higher maximum load voltage (280V vs. 265V), making it compatible with all applications designed for the RAM1A23D25.

Q: What is the significance of the load voltage difference between these parts?

A: The RAM1A23D25 is rated for loads up to 265V AC, while the 84137010 extends to 280V AC. For applications operating below 265V, both parts are functionally equivalent. For applications requiring operation between 265V and 280V, only the 84137010 is suitable.

Q: Are there differences in compliance or certification between these relays?

A: The 84137010 is RoHS3 compliant and REACH Affected, while the RAM1A23D25 is REACH Unaffected. Both are classified as EAR99 for export control. Selection should align with applicable regulatory requirements for your application and market.

Q: Do these relays require different installation procedures?

A: No. Both relays use identical screw terminal connections and chassis mount configurations. Installation procedures, wiring practices, and mechanical mounting are interchangeable.

Q: What control voltage range do these relays accept?

A: Both the RAM1A23D25 and 84137010 accept control input voltages from 3VDC to 32VDC, providing flexibility for integration with various control circuit designs and logic level signals.
