Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPF240A25R is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain identical switching functionality
• Output Type: Must be AC to match load switching characteristics
• Voltage - Input: Must support 90–140VAC input range
• Voltage - Load: Must support 12–280V load voltage range
• Load Current: Must be rated for 25A continuous operation
• Package / Case: Must be 4-SIP to ensure mechanical and electrical compatibility with existing PCB layouts
• Termination Style: Must use PC Pin termination for direct board mounting compatibility
• Mounting Type: Must be Through Hole to match assembly requirements

The PF240A25R meets all these criteria and is classified as the manufacturer-recommended substitute. Both parts share identical electrical specifications and mechanical form factors, with the primary distinction being product lifecycle status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The PF240A25R is the direct equivalent substitute for the SPF240A25R. Both components are manufactured by Sensata-Crydom and share identical electrical and mechanical specifications across all critical parameters. The PF240A25R is currently in Active product status with 968 units in stock, providing superior supply chain availability compared to the Last Time Buy SPF240A25R.

The PF240A25R carries additional regulatory approvals (CE, cURus, TUV) and meets ROHS3 compliance, compared to the RoHS Compliant designation of the SPF240A25R. Both parts are classified under the same ECCN and HTSUS codes, confirming regulatory equivalence.

For new designs or replenishment of existing applications, the PF240A25R is the appropriate selection due to its Active status and enhanced compliance certifications. Existing assemblies using the SPF240A25R may be directly replaced with the PF240A25R without circuit modification or PCB redesign.

Frequently Asked Questions (FAQ)

Q: Can the PF240A25R be used as a direct replacement for the SPF240A25R in existing assemblies?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters: SPST-NO circuit configuration, 25A load current rating, 90–140VAC input, 12–280V load voltage, 4-SIP package, and PC Pin termination. No circuit modification or PCB redesign is required.

Q: What is the difference between the SPF240A25R and PF240A25R?

A: The primary differences are product lifecycle status and regulatory certifications. The SPF240A25R is Last Time Buy, while the PF240A25R is Active. The PF240A25R includes CE, cURus, and TUV approvals and meets ROHS3 compliance. Electrical and mechanical specifications are identical.

Q: Why should I transition from SPF240A25R to PF240A25R?

A: The SPF240A25R is designated Last Time Buy, indicating limited future availability. The PF240A25R is in Active status with higher inventory levels (968 units vs. 850 units), ensuring reliable supply chain continuity for current and future production requirements.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the 4-SIP package with PC Pin termination and Through Hole mounting. Pinout and mechanical dimensions are identical, enabling direct PCB compatibility.

Q: What compliance certifications apply to the PF240A25R?

A: The PF240A25R holds CE, cURus, and TUV approvals and meets ROHS3 compliance. Both parts are classified under ECCN EAR99 and HTSUS 8536.49.0080.
