SSRF-480D25R Solid State Relay Equivalent & Substitute Parts

Part Overview

The SSRF-480D25R is an active solid state relay manufactured by TE Connectivity Potter & Brumfield Relays. This component is a SPST-NO (Single Pole Single Throw - Normally Open) relay configured as a 1 Form A switch with AC output capability. The relay is rated for 25 A load current and operates across a load voltage range of 48 V to 660 V, with input control voltage between 3 V and 15 VDC. The device is packaged in a 4-SIP through-hole configuration with PC pin termination.

Equivalent and substitute parts are identified based on matching electrical specifications, mechanical compatibility, and functional equivalence. Alternative models may be required due to component availability, supply chain considerations, or specific application requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SSRF-480D25R are identified based on the following critical parameters that determine functional equivalence:

Matching Criteria:

• Circuit configuration: SPST-NO (1 Form A)
• Load current rating: 25 A
• Input control voltage range: 3 ~ 15 VDC
• Package type: 4-SIP
• Termination style: PC Pin
• Mounting type: Through Hole
• Output type: AC

Substitution Logic: The identified substitute parts (SPF240D25 and SPFE240D25) share identical circuit configuration, load current rating, input voltage range, package format, and termination style with the SSRF-480D25R. These components are functionally equivalent for applications requiring SPST-NO relay operation at 25 A with 3-15 VDC control input.

Parameter Variance: Load voltage range differs between the main part and substitutes. The SSRF-480D25R operates across 48 V to 660 V, while substitute parts operate across 12 V to 280 V. This variance requires application-specific evaluation to confirm compatibility with the intended load voltage environment.

Parameter Comparison

Engineering Selection Recommendations

SSRF-480D25R (Primary Part): The SSRF-480D25R is an active product with ROHS3 compliance and unlimited moisture sensitivity rating. This component is suitable for applications requiring AC load switching at 25 A across the extended voltage range of 48 V to 660 V with 3-15 VDC control input.

SPF240D25 (Substitute Option): The SPF240D25 is an active product manufactured by Sensata-Crydom with ROHS3 compliance and unlimited moisture sensitivity rating. This component provides functional equivalence for SPST-NO relay operation at 25 A with 3-15 VDC input control. The SPF240D25 includes zero-cross switching capability. Load voltage operation is limited to 12 V to 280 V, which restricts this substitute to applications within this voltage range.

SPFE240D25 (Substitute Option): The SPFE240D25 is an active product manufactured by Sensata-Crydom with ROHS3 compliance and unlimited moisture sensitivity rating. This component provides functional equivalence for SPST-NO relay operation at 25 A. The input control voltage range is 15-32 VDC, which differs from the SSRF-480D25R specification of 3-15 VDC. The SPFE240D25 includes zero-cross switching capability. Load voltage operation is limited to 12 V to 280 V.

All three components are active products with equivalent environmental compliance certifications. Selection between the main part and substitutes depends on application-specific load voltage requirements and control input voltage availability.

Frequently Asked Questions (FAQ)

Q: Can SPF240D25 directly replace SSRF-480D25R in all applications?

A: SPF240D25 shares identical circuit configuration, load current rating, input voltage range, package type, and termination style with SSRF-480D25R. However, the load voltage range differs: SPF240D25 operates at 12 V to 280 V, while SSRF-480D25R operates at 48 V to 660 V. Direct replacement is limited to applications where the load voltage remains within the 12 V to 280 V range.

Q: What is the difference between SPF240D25 and SPFE240D25?

A: Both parts are manufactured by Sensata-Crydom and share identical load voltage range (12 V to 280 V), load current (25 A), package type (4-SIP), and circuit configuration (SPST-NO). The primary difference is input control voltage: SPF240D25 accepts 3-15 VDC input, while SPFE240D25 accepts 15-32 VDC input. Selection depends on available control voltage in the application.

Q: Are all three parts RoHS compliant?

A: Yes. SSRF-480D25R, SPF240D25, and SPFE240D25 are all ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: What does the 4-SIP package format indicate?

A: 4-SIP indicates a 4-pin Single In-line Package configuration. All three parts use this identical package format with PC pin termination for through-hole mounting on printed circuit boards.

Q: Can SPFE240D25 be used where SSRF-480D25R is specified?

A: SPFE240D25 shares identical circuit configuration, load current, package type, and termination style with SSRF-480D25R. However, two parameter differences exist: input control voltage (SPFE240D25 requires 15-32 VDC versus SSRF-480D25R's 3-15 VDC) and load voltage range (SPFE240D25 operates at 12-280 V versus SSRF-480D25R's 48-660 V). Substitution requires confirmation that both the control voltage and load voltage specifications are compatible with the application.

Q: What is zero-cross switching capability?

A: Zero-cross switching is a feature present in SPF240D25 and SPFE240D25 that synchronizes relay switching with the AC voltage waveform zero-crossing point. SSRF-480D25R does not specify this feature. This difference does not prevent substitution but may affect switching characteristics in specific applications.

Q: Are there inventory considerations for these parts?

A: SSRF-480D25R has 1083 pieces in stock, SPF240D25 has 1265 pieces in stock, and SPFE240D25 has 951 pieces in stock. All parts are available as new original components in bulk packaging.
