HPF480D20R Equivalent & Substitute Parts

Part Overview

The HPF480D20R is a solid-state relay (SSR) manufactured by Sensata-Crydom, configured as a SPST-NO (1 Form A) module with a 30A load capacity and 48–660V output voltage range. This component is designed for DIN rail mounting with screw terminal connections and operates on 4.5–32VDC input control voltage.

The HPF480D20R is classified as obsolete. Locating equivalent or substitute parts is necessary to support system maintenance, repair, and replacement requirements where this model is no longer available through standard distribution channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HPF480D20R is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain identical switching functionality
• Output Type: Must be AC to match load switching requirements
• Mounting Type: Must be DIN Rail to ensure mechanical compatibility with existing installations
• Termination Style: Must be Screw Terminal for direct connection compatibility
• Voltage - Input: Must operate within or encompass the 4.5–32VDC control voltage range
• Voltage - Load: Must support the 48–660V output voltage range or a subset thereof
• Load Current: Must support at least 30A, or a lower rating if the application permits

The CKRD4820-10 is identified as a manufacturer-recommended substitute. This part maintains the same circuit configuration, output type, mounting type, and termination style. While the load current rating is reduced to 20A and the maximum load voltage is limited to 530V, these parameters define the operational envelope for this substitute in applications where the lower ratings are acceptable.

Parameter Comparison

Engineering Selection Recommendations

The CKRD4820-10 is the manufacturer-recommended substitute for the HPF480D20R. Both parts are classified as obsolete and manufactured by Sensata-Crydom.

Selection of the CKRD4820-10 requires verification that the application load current does not exceed 20A and that the maximum load voltage does not exceed 530V. The CKRD4820-10 features an integrated heat sink, which may provide thermal management advantages in certain installations.

The CKRD4820-10 is RoHS Compliant, whereas the HPF480D20R compliance status is not specified in available documentation. Both parts carry ECCN EAR99 classification and fall under HTSUS code 8536.49.0080.

Frequently Asked Questions (FAQ)

Q: Can the CKRD4820-10 directly replace the HPF480D20R in all applications?

A: Direct replacement is possible only if the application load current does not exceed 20A and the maximum load voltage does not exceed 530V. The HPF480D20R supports up to 30A and 660V; the CKRD4820-10 is rated for 20A and 530V maximum. Verify load requirements before substitution.

Q: Are there mechanical compatibility concerns when substituting the CKRD4820-10?

A: Both parts are DIN rail mounted with screw terminal connections. The CKRD4820-10 includes an integrated heat sink, which may affect mounting clearance in confined spaces. Physical verification of the installation environment is necessary.

Q: What is the difference in input voltage range between these parts?

A: The HPF480D20R operates on 4.5–32VDC input, while the CKRD4820-10 operates on 4–32VDC input. The CKRD4820-10 has a lower minimum input voltage threshold by 0.5V, which is operationally insignificant in most control circuits.

Q: Why is the CKRD4820-10 rated for lower load current and voltage than the HPF480D20R?

A: The CKRD4820-10 represents a different design within the Sensata-Crydom SSR product line. Lower current and voltage ratings reflect the specific thermal and electrical design of this model. The integrated heat sink may enable more compact packaging at the cost of reduced maximum ratings.

Q: Are both parts RoHS compliant?

A: The CKRD4820-10 is confirmed RoHS Compliant. The HPF480D20R RoHS status is not specified in available documentation. Both parts are REACH Unaffected.
