SPFE240D25R Equivalent & Substitute Parts

Part Overview

The SPFE240D25R is a solid-state relay (SSR) manufactured by Sensata Technologies, classified as a SPST-NO (1 Form A) switching device. This component operates as a 25A AC output relay with input voltage range of 15–32VDC and load voltage capability of 12–280V. The device is mounted through-hole in a 4-SIP package configuration and maintains active product status with full RoHS compliance. Equivalent and substitute parts are identified to provide procurement flexibility, inventory alternatives, and supply chain continuity for applications requiring SPST-NO solid-state relay functionality within the specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SPFE240D25R are identified based on functional equivalence within the following critical parameters:

• Circuit configuration: SPST-NO (1 Form A) topology
• Output type: AC switching capability
• Load current rating: 25 A
• Package form factor: 4-SIP through-hole mounting
• Termination style: PC Pin configuration
• Load voltage range: Minimum 12V operation (upper limit 280V acceptable)
• Input voltage compatibility: Overlap within control signal range

The substitute part ASR-SH240D25RW meets these criteria with the following considerations: input voltage range extends to 4VDC minimum (lower than SPFE240D25R), and load voltage minimum is 24V (higher than SPFE240D25R). These differences define the substitution boundaries and application-specific compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the SPFE240D25R and ASR-SH240D25RW are active products with current manufacturing status. The SPFE240D25R carries RoHS Compliant certification, while the ASR-SH240D25RW meets ROHS3 Compliant and REACH Unaffected standards, indicating enhanced environmental compliance documentation.

Selection between these parts depends on application-specific voltage requirements:

• Use SPFE240D25R when load voltage operation below 24V is required (12–23V range)
• Use ASR-SH240D25RW when input control voltage below 15VDC is required (4–14VDC range)
• Both parts are suitable for applications operating within the overlapping ranges: input 15–32VDC and load 24–280V

Frequently Asked Questions (FAQ)

Q: Can ASR-SH240D25RW replace SPFE240D25R in all applications?

A: No. The ASR-SH240D25RW has a minimum load voltage of 24V, while the SPFE240D25R operates down to 12V. Substitution is valid only for applications where load voltage remains at 24V or higher.

Q: What is the input voltage overlap between these parts?

A: Both parts operate within the 15–32VDC input range. The ASR-SH240D25RW extends lower to 4VDC, but this extended range is not relevant for direct substitution with the SPFE240D25R unless the application specifically requires sub-15VDC control signals.

Q: Are the 4-SIP packages mechanically identical?

A: Both parts use 4-SIP through-hole packages with PC Pin termination. Mechanical compatibility is confirmed for PCB layout purposes.

Q: What compliance differences exist between these parts?

A: The SPFE240D25R is RoHS Compliant. The ASR-SH240D25RW meets ROHS3 Compliant and REACH Unaffected certifications, providing additional environmental compliance documentation suitable for regulated markets.

Q: Can these parts be used interchangeably for 25A AC switching at 280V?

A: Yes, both parts are rated for 25A load current and 280V maximum load voltage. Interchangeability is confirmed for this operating point.
