SPFE480D25 Equivalent & Substitute Parts

Part Overview

The SPFE480D25 is a solid-state relay (SSR) manufactured by Sensata-Crydom, configured as a SPST-NO (1 Form A) device in a 4-SIP package. This component operates with a 15–32VDC input and controls AC loads up to 25A across a 48–660V range, incorporating zero-cross switching for reduced electromagnetic interference. The product is active and RoHS compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

The ASR-SH480D25ZW qualifies as a substitute based on the following alignment of critical parameters:

• Circuit Configuration: Both devices are SPST-NO (1 Form A) solid-state relays
• Output Type: Both employ AC switching with zero-cross functionality
• Load Current: Both are rated for 25A continuous operation
• Package & Mounting: Both use 4-SIP through-hole packages with PC pin termination
• Input Voltage Compatibility: The ASR-SH480D25ZW accepts 4–32VDC input, which encompasses the SPFE480D25 requirement of 15–32VDC
• Load Voltage Range: The ASR-SH480D25ZW operates across 24–530V, which overlaps the SPFE480D25 range of 48–660V within the 48–530V intersection

Substitution is valid where the load voltage requirement does not exceed 530V.

Parameter Comparison

Engineering Selection Recommendations

Both the SPFE480D25 and ASR-SH480D25ZW are active products with current manufacturing status. The SPFE480D25 carries RoHS compliance, while the ASR-SH480D25ZW meets ROHS3 compliance and is REACH unaffected. Selection between these devices depends on load voltage requirements: the SPFE480D25 supports operation up to 660V, whereas the ASR-SH480D25ZW is limited to 530V. For applications requiring load voltages above 530V, the SPFE480D25 is the only suitable option. For applications within the 48–530V range, both devices are electrically and mechanically compatible.

Frequently Asked Questions (FAQ)

Q: Can the ASR-SH480D25ZW replace the SPFE480D25 in all applications?

A: No. The ASR-SH480D25ZW has a maximum load voltage rating of 530V, while the SPFE480D25 supports up to 660V. Substitution is valid only when the load voltage does not exceed 530V.

Q: Are the input voltage ranges compatible?

A: Yes. The SPFE480D25 requires 15–32VDC input, and the ASR-SH480D25ZW accepts 4–32VDC. The ASR-SH480D25ZW's broader input range is compatible with the SPFE480D25 specification.

Q: Do both devices use the same package and mounting?

A: Yes. Both are 4-SIP through-hole packages with PC pin termination, ensuring mechanical and electrical compatibility on the same PCB layout.

Q: What is the difference in RoHS compliance?

A: The SPFE480D25 is RoHS compliant, and the ASR-SH480D25ZW is ROHS3 compliant. Both meet current environmental regulations; ROHS3 represents a more recent compliance standard.

Q: Are there any load current differences?

A: No. Both devices are rated for 25A continuous load current.
