SSRF-480D25 Solid State Relay SPST-NO 25A 48-660V Equivalent & Substitute Parts

Part Overview

The SSRF-480D25 is a solid state relay (SSR) manufactured by TE Connectivity Potter & Brumfield Relays. This component is a SPST-NO (Single Pole Single Throw - Normally Open) relay in 4-SIP package configuration, rated for 25A load current with AC output and zero-cross switching capability. The device operates with 3-15VDC input control voltage and supports load voltages from 48V to 660V.

The SSRF-480D25 maintains Active product status. Equivalent and substitute parts are identified to provide design flexibility, support supply chain alternatives, and accommodate specific application requirements where voltage or input specifications differ from the primary part number.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSRF-480D25 is determined by the following critical parameters that must remain constant across equivalent parts:

Fixed Parameters (Must Match):

• Circuit configuration: SPST-NO (1 Form A)
• Load current rating: 25 A
• Output type: AC, Zero Cross
• Package / Case: 4-SIP
• Termination style: PC Pin
• Mounting type: Through Hole
• Moisture sensitivity level: 1 (Unlimited)

Variable Parameters (Allowed to Differ):

• Voltage - Input: Control voltage range may vary between 3-15VDC and 15-32VDC
• Voltage - Load: Load voltage range may vary within operational limits
• Manufacturer and series designation

The substitute parts SPF240D25 and SPFE240D25 (both Sensata-Crydom) maintain all fixed parameters while operating within different input and load voltage specifications. These parts are functionally interchangeable in applications where the load voltage requirement falls within 12-280V range and the control input voltage aligns with the specific part's input specification.

Parameter Comparison

Engineering Selection Recommendations

SSRF-480D25 (Primary Part): Select this part for applications requiring load voltage operation up to 660V with input control voltage in the 3-15VDC range. This part maintains Active product status from TE Connectivity Potter & Brumfield Relays.

SPF240D25 (Sensata-Crydom Substitute): This part is suitable for applications with load voltage requirements between 12-280V and input control voltage between 3-15VDC. The SPF240D25 is ROHS3 Compliant and REACH Unaffected, providing enhanced regulatory compliance compared to the primary part.

SPFE240D25 (Sensata-Crydom Substitute): This part is suitable for applications with load voltage requirements between 12-280V and input control voltage between 15-32VDC. The SPFE240D25 is ROHS3 Compliant and REACH Unaffected, providing enhanced regulatory compliance compared to the primary part.

Selection between substitute parts depends on the specific input control voltage requirement of the application. Both Sensata-Crydom alternatives maintain identical load current rating, circuit configuration, output type, and package specifications as the primary part.

Frequently Asked Questions (FAQ)

Q: Can SPF240D25 or SPFE240D25 be used as direct replacements for SSRF-480D25?

A: Direct replacement is possible only when the application load voltage requirement falls within the 12-280V range. The SSRF-480D25 supports load voltages up to 660V, which exceeds the capability of both substitute parts. Verify that your application load voltage does not exceed 280V before selecting a substitute part.

Q: What is the difference between SPF240D25 and SPFE240D25?

A: Both parts are manufactured by Sensata-Crydom and share identical load current rating, circuit configuration, output type, and package specifications. The primary difference is the input control voltage range: SPF240D25 operates with 3-15VDC input, while SPFE240D25 operates with 15-32VDC input. Select the part that matches your control circuit voltage.

Q: Are the substitute parts pin-compatible with SSRF-480D25?

A: Yes. All three parts use identical 4-SIP package configuration with PC Pin termination style and Through Hole mounting type. Pin compatibility is maintained across all three part numbers.

Q: Do the substitute parts have better regulatory compliance?

A: Yes. Both SPF240D25 and SPFE240D25 are ROHS3 Compliant and REACH Unaffected. The SSRF-480D25 has Not applicable RoHS status and Vendor Undefined REACH status. If regulatory compliance is a requirement, the Sensata-Crydom alternatives provide documented compliance.

Q: What is the load current rating for all three parts?

A: All three parts are rated for 25A load current with AC output and zero-cross switching capability.

Q: Can these parts be used interchangeably in the same PCB design?

A: Yes, provided that the application load voltage requirement is within 12-280V range and the control input voltage matches the selected part's specification. The identical 4-SIP package and PC Pin termination ensure mechanical and electrical compatibility on the PCB.
