SSRF-240D25R Solid State Relay Equivalent & Substitute Parts

Part Overview

The SSRF-240D25R 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 with a 1 Form A circuit configuration, rated for 25 A load current and 12 V to 280 V AC output operation. The relay accepts 3 V to 15 VDC input control voltage and is packaged in a 4-SIP through-hole configuration with PC pin termination.

The SSRF-240D25R maintains Active product status and is RoHS3 compliant with unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified to provide design flexibility, supply chain alternatives, and component availability options for applications requiring identical or compatible electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSRF-240D25R is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: SPST-NO (1 Form A)
• Load current rating: 25 A
• Load voltage range: 12 V ~ 280 V
• Package type: 4-SIP
• Termination style: PC Pin
• Mounting type: Through Hole

Input Voltage Consideration: The SSRF-240D25R operates with 3 V to 15 VDC input control voltage. Substitute parts must either match this input voltage range or provide a compatible range that encompasses the application's control voltage requirements.

Output Type Consideration: The SSRF-240D25R provides AC output switching. Substitute parts with AC or AC with Zero Cross output capability are functionally compatible for AC load applications.

Two substitute parts meet these criteria: SPF240D25 and SPFE240D25, both manufactured by Sensata-Crydom. Both maintain identical load current, load voltage, package configuration, and termination specifications. The SPF240D25 matches the input voltage range (3 V ~ 15 VDC) of the main part. The SPFE240D25 operates with a different input voltage range (15 V ~ 32 VDC) and is suitable for applications requiring higher control voltage input.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (SPF240D25): The SPF240D25 manufactured by Sensata-Crydom is a direct functional equivalent to the SSRF-240D25R. Both components share identical input voltage range (3 V ~ 15 VDC), load current rating (25 A), load voltage range (12 V ~ 280 V), package configuration (4-SIP), and termination style (PC Pin). The SPF240D25 includes Zero Cross output capability, which provides enhanced performance in AC switching applications by synchronizing switching transitions with AC voltage zero crossings. Both parts maintain Active product status, ROHS3 compliance, and REACH unaffected status.

Alternative for Higher Input Voltage Applications (SPFE240D25): The SPFE240D25 manufactured by Sensata-Crydom is suitable for applications requiring 15 V to 32 VDC input control voltage. This part maintains identical load specifications (25 A, 12 V ~ 280 V), package configuration (4-SIP), and termination style (PC Pin) as the SSRF-240D25R. The SPFE240D25 is not a direct substitute for the SSRF-240D25R due to the different input voltage range but serves as an alternative for designs operating with higher control voltage inputs. Both parts maintain Active product status, ROHS3 compliance, and REACH unaffected status.

All three parts are certified to ROHS3 standards and carry REACH unaffected status, ensuring regulatory compliance across applications.

Frequently Asked Questions (FAQ)

Q: Can the SPF240D25 be used as a direct replacement for the SSRF-240D25R?

A: Yes. The SPF240D25 is a direct functional equivalent. Both components operate with identical input voltage (3 V ~ 15 VDC), load current (25 A), load voltage (12 V ~ 280 V), package type (4-SIP), and termination style (PC Pin). The SPF240D25 includes Zero Cross output capability, which enhances AC switching performance.

Q: What is the difference between the SPF240D25 and SPFE240D25?

A: The primary difference is the input control voltage range. The SPF240D25 operates with 3 V ~ 15 VDC input, matching the SSRF-240D25R specification. The SPFE240D25 operates with 15 V ~ 32 VDC input. Both maintain identical load current (25 A), load voltage (12 V ~ 280 V), and package specifications (4-SIP).

Q: Can the SPFE240D25 replace the SSRF-240D25R in an existing design?

A: The SPFE240D25 is not a direct replacement for the SSRF-240D25R due to the different input voltage requirement (15 V ~ 32 VDC versus 3 V ~ 15 VDC). Use the SPFE240D25 only if your application control voltage is within the 15 V ~ 32 VDC range. For applications requiring 3 V ~ 15 VDC input, use the SPF240D25.

Q: Are all three parts RoHS compliant?

A: Yes. The SSRF-240D25R, SPF240D25, and SPFE240D25 are all ROHS3 compliant with REACH unaffected status.

Q: What does Zero Cross output mean on the substitute parts?

A: Zero Cross output capability synchronizes the relay switching transition with the AC voltage zero crossing point. This reduces electromagnetic interference and switching noise in AC load applications compared to standard AC output switching.

Q: Are the package and pin configurations identical across all three parts?

A: Yes. All three parts use 4-SIP package type with PC pin termination and through-hole mounting configuration, ensuring mechanical and electrical compatibility on printed circuit boards designed for the SSRF-240D25R.

Q: What is the inventory status of substitute parts?

A: The SPF240D25 has 1265 pieces in stock, and the SPFE240D25 has 951 pieces in stock. Both are available as new original components.
