SPF380D25 Equivalent & Substitute Parts

Part Overview

The SPF380D25 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 input voltage of 4–15VDC and controls AC loads up to 25A at 48–530V with zero-cross switching. The SPF380D25 is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPF380D25 is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A)
• Output Type: Must be AC with zero-cross switching
• Load Current: Must support 25A
• Package / Case: Must be 4-SIP
• Mounting Type: Must be Through Hole
• Termination Style: Must be PC Pin
• Input Voltage Range: Must accommodate 4–15VDC control signals
• Load Voltage Range: Must support minimum 48V operation

Substitute parts are grouped into two categories:

MFR Recommended: PF380D25 (Sensata-Crydom) — Direct successor within the same manufacturer's product line, maintaining identical electrical and mechanical specifications while transitioning from obsolete to active product status.

Similar: ASR-SH480D25ZW (Altran Magnetics, LLC) — Alternative manufacturer offering equivalent functionality with compatible electrical parameters and identical package form factor, though with extended input voltage range (4–32VDC) and lower minimum load voltage (24V).

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: PF380D25

The PF380D25 is the manufacturer-recommended substitute for the obsolete SPF380D25. Both components are manufactured by Sensata-Crydom and share identical electrical specifications and package form factor. The PF380D25 maintains active product status and meets ROHS3 compliance requirements, making it the preferred choice for direct replacement in existing designs and new implementations.

Alternative Recommendation: ASR-SH480D25ZW

The ASR-SH480D25ZW from Altran Magnetics, LLC provides functional equivalence with compatible electrical and mechanical parameters. This alternative offers an extended input voltage range (4–32VDC) and lower minimum load voltage threshold (24V), providing greater operational flexibility in applications with variable control signal levels. The ASR-SH480D25ZW meets ROHS3 compliance and REACH unaffected status. Selection of this alternative is appropriate when the extended input voltage range provides system-level advantages or when supply chain considerations favor Altran Magnetics sourcing.

Frequently Asked Questions (FAQ)

Q: Can the PF380D25 be used as a direct replacement for the SPF380D25?

A: Yes. The PF380D25 is the manufacturer-recommended successor and maintains identical electrical specifications (4–15VDC input, 48–530V load, 25A capacity) and mechanical form factor (4-SIP, through-hole, PC pin termination). No circuit modifications are required.

Q: What are the key differences between the PF380D25 and ASR-SH480D25ZW?

A: Both components meet the core substitution criteria for SPST-NO, 25A, 4-SIP solid-state relays. The ASR-SH480D25ZW extends the input voltage range to 4–32VDC and reduces the minimum load voltage to 24V, compared to the PF380D25's 4–15VDC input and 48V minimum load. Both maintain zero-cross AC switching and identical current capacity.

Q: Are there any compliance differences between these substitutes?

A: The SPF380D25 is RoHS Compliant. Both the PF380D25 and ASR-SH480D25ZW meet the more stringent ROHS3 Compliant standard. The ASR-SH480D25ZW carries REACH Unaffected status, while the PF380D25 also carries REACH Unaffected status. All three components are classified under ECCN EAR99.

Q: Does the 4-SIP package form factor remain consistent across all three parts?

A: Yes. The SPF380D25, PF380D25, and ASR-SH480D25ZW all use the 4-SIP package with through-hole mounting and PC pin termination, ensuring mechanical compatibility in existing PCB layouts.

Q: Which substitute should be selected for new designs?

A: The PF380D25 is recommended for new designs as the active, manufacturer-supported product from Sensata-Crydom. The ASR-SH480D25ZW is appropriate when the extended input voltage range (4–32VDC) or lower minimum load voltage (24V) provides specific system advantages.
