PF480D25R Equivalent & Substitute Parts

Part Overview

The PF480D25R is a solid-state relay (SSR) manufactured by Sensata-Crydom, classified as a SPST-NO (1 Form A) device in a 4-SIP package. This component is designed for AC load switching applications with a rated load current of 25A and operates across a load voltage range of 48V to 660V. The device features through-hole PC pin termination and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1). As an active product with established supply availability, equivalent alternatives exist for applications requiring substitution due to inventory constraints or specific operational requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PF480D25R 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 ensure compatibility with the intended load
• Load Current Rating: Must be rated for 25A minimum to handle the specified load
• Package and Termination: Must use 4-SIP package with PC pin termination for mechanical and electrical compatibility
• Mounting Type: Must support through-hole mounting for PCB integration

The substitute part ASR-SH480D25RW meets these core substitution criteria. While the load voltage range differs (24V to 530V versus 48V to 660V), the input voltage range is broader (4 to 32VDC versus 4 to 15VDC), and the packaging remains identical, this part functions as an equivalent within overlapping operational parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the PF480D25R and ASR-SH480D25RW are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. Selection between these parts should be based on the specific load voltage requirements of the application. The PF480D25R supports higher maximum load voltages (660V) and is suitable for applications requiring operation across the full 48V to 660V range. The ASR-SH480D25RW operates within a 24V to 530V load voltage window and offers a broader input voltage acceptance range (4 to 32VDC), making it suitable for applications with variable input supply conditions within that specification.

Frequently Asked Questions (FAQ)

Q: Can the ASR-SH480D25RW replace the PF480D25R in all applications?

A: Substitution is valid only when the load voltage requirement falls within the 24V to 530V range. Applications requiring load voltages above 530V or below 24V must use the PF480D25R.

Q: Are the input voltage ranges compatible between these parts?

A: The PF480D25R accepts 4 to 15VDC input, while the ASR-SH480D25RW accepts 4 to 32VDC input. The ASR-SH480D25RW accommodates a broader input range. Both parts function within the 4 to 15VDC overlap region.

Q: Do these parts use identical packaging?

A: Yes. Both parts use 4-SIP package configuration with PC pin through-hole termination, ensuring mechanical compatibility on standard PCB layouts.

Q: What is the significance of the different series designations (PF versus SH)?

A: The series designation indicates the manufacturer's product line. PF (PowerFin™) is Sensata-Crydom's series, while SH is Altran Magnetics' series. The series does not affect functional equivalence when electrical and mechanical parameters match.

Q: Are both parts suitable for new designs?

A: Both parts carry active product status and current regulatory compliance (ROHS3, REACH unaffected), making them suitable for new design implementations.
