HPF240D30 Equivalent & Substitute Parts

Part Overview

The HPF240D30 is a solid-state relay (SSR) module manufactured by Sensata-Crydom, designed for SPST-NO (1 Form A) switching applications. This component operates with a 12–280V AC load at 30A capacity and features zero-cross switching for AC applications. The HPF240D30 is classified as obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HPF240D30 is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain identical switching topology
• Output Type: Must support AC switching with zero-cross capability
• Input Voltage Range: Must accommodate 4–32VDC control signal
• Load Voltage Range: Must support minimum 12V and maximum 280V operation
• Load Current: Must be rated for 30A continuous operation
• Mounting Type: Must be DIN Rail compatible
• Termination Style: Must use Screw Terminal connections

The CKRD2430 meets these substitution criteria with the exception of minimum load voltage specification (24V vs. 12V), which represents a functional constraint for applications requiring sub-24V load switching.

Parameter Comparison

Engineering Selection Recommendations

The CKRD2430 is the designated substitute for the obsolete HPF240D30 based on functional equivalence across all critical electrical parameters. Both components are manufactured by Sensata Technologies (Sensata-Crydom and Sensata Technologies are related entities), ensuring design continuity and supply chain reliability.

The CKRD2430 offers the following advantages:

• Active product status ensures ongoing availability and manufacturer support
• RoHS3 compliance meets current environmental and regulatory standards
• Integrated heat sink design improves thermal management compared to the standard module package
• Minimum load voltage specification of 24V is suitable for industrial AC applications operating above this threshold

For applications requiring load switching below 24V, alternative components outside the provided substitute list must be evaluated.

Frequently Asked Questions (FAQ)

Q: Can the CKRD2430 directly replace the HPF240D30 in all applications?

A: The CKRD2430 is functionally equivalent for applications where the load voltage remains at or above 24V. The HPF240D30 supports load voltages as low as 12V, while the CKRD2430 minimum is 24V. Verify your application's load voltage specification before substitution.

Q: What is the significance of the integrated heat sink in the CKRD2430?

A: The integrated heat sink improves thermal dissipation during continuous 30A operation, potentially extending component life and improving reliability in high-ambient-temperature environments. The standard HPF240D30 module lacks this feature.

Q: Are both components DIN Rail mountable?

A: Yes. Both the HPF240D30 and CKRD2430 are designed for DIN Rail mounting with screw terminal connections, ensuring mechanical compatibility in existing installations.

Q: What is the difference between Sensata-Crydom and Sensata Technologies?

A: Sensata-Crydom is a product line within Sensata Technologies. Both designations refer to the same manufacturer, and components from either designation are sourced through the same supply chain.

Q: Does the CKRD2430 meet RoHS compliance?

A: Yes. The CKRD2430 is RoHS3 compliant, meeting current environmental regulations. The HPF240D30 status is not specified in the provided data.

Q: Are the input voltage specifications identical?

A: Yes. Both components accept 4–32VDC control input, ensuring control circuit compatibility without modification.
