HPF480D30 Equivalent & Substitute Parts

Part Overview

The HPF480D30 is a solid-state relay (SSR) manufactured by Sensata Technologies, configured as a single-pole, single-throw normally open (SPST-NO) module rated for 30A load current at 48–660V AC output. This component operates with 4.5–32VDC input control voltage and features zero-cross switching for AC loads. The HPF480D30 is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations.

Substitute Part Grouping Explanation

Substitution of the HPF480D30 is determined by equivalence across the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain identical switching topology
• Output Type: Must be AC with zero-cross switching to preserve load control characteristics
• Load Current Rating: Must be rated for 30A minimum
• Voltage - Input: Must accommodate 4.5–32VDC control signal range
• Voltage - Load: Must support the required AC load voltage range
• Mounting Type: Must be DIN Rail compatible for mechanical fit
• Termination Style: Must use screw terminals for electrical connection compatibility

The CKRD4830 meets these substitution criteria with the following considerations: input voltage range is 4–32VDC (slightly lower minimum), and maximum load voltage is 530V (lower than the HPF480D30's 660V maximum). These differences represent functional constraints that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The CKRD4830 is the manufacturer-recommended substitute for the HPF480D30. Both components share identical circuit topology, load current rating, and switching characteristics. The CKRD4830 is currently in active production status, whereas the HPF480D30 is obsolete.

Key differences affecting selection:

• Input Voltage Range: The CKRD4830 minimum input voltage is 4VDC versus 4.5VDC for the HPF480D30. Applications requiring operation below 4VDC cannot use the CKRD4830.
• Maximum Load Voltage: The CKRD4830 is rated to 530V AC maximum, compared to 660V for the HPF480D30. Applications requiring operation above 530V AC cannot use the CKRD4830.
• Thermal Management: The CKRD4830 includes an integrated heat sink, providing enhanced thermal dissipation compared to the standard module package of the HPF480D30.
• Regulatory Compliance: The CKRD4830 is ROHS3 compliant and REACH affected, whereas the HPF480D30 is REACH unaffected. Regulatory requirements for the target application determine compliance necessity.

Frequently Asked Questions (FAQ)

Q: Can the CKRD4830 directly replace the HPF480D30 in all applications?

A: The CKRD4830 is functionally equivalent for applications operating within its specified ranges: 4–32VDC input and 48–530V AC load voltage. Applications requiring input voltages below 4VDC or load voltages above 530V AC require evaluation of alternative substitutes or retention of the original HPF480D30 if available.

Q: What is the significance of the integrated heat sink in the CKRD4830?

A: The integrated heat sink improves thermal dissipation during continuous 30A operation, reducing junction temperature and potentially extending component life in thermally constrained environments. The standard HPF480D30 module lacks this feature.

Q: Are there mechanical compatibility concerns between HPF480D30 and CKRD4830?

A: Both components are DIN Rail mounted with screw terminal connections. Physical dimensions may differ due to the integrated heat sink on the CKRD4830. Verify mounting space and terminal clearance in the target installation before substitution.

Q: What compliance differences exist between these components?

A: The CKRD4830 is ROHS3 compliant and REACH affected, indicating compliance with current environmental regulations. The HPF480D30 is REACH unaffected, indicating it was manufactured under earlier regulatory frameworks. New designs should prioritize the CKRD4830 for regulatory alignment.

Q: How do I determine if the CKRD4830 is suitable for my specific application?

A: Verify that your application operates within these parameters: input control voltage 4–32VDC, load voltage 48–530V AC, and load current 30A maximum. If all parameters fall within these ranges, the CKRD4830 is electrically compatible. Confirm mechanical fit and thermal requirements independently.
