Key Parameters

Substitute Part Grouping Explanation

Substitution of the CPF240D25 is determined by strict equivalence across the following parameters:

• Circuit configuration must remain SPST-NO (1 Form A)
• Load current rating must be 25 A minimum
• Output voltage range must encompass 12 V ~ 280 V
• Input control voltage must operate within 3 ~ 15 VDC
• Output switching must include AC with zero-cross capability
• Package must be 4-SIP with through-hole mounting
• Termination must be PC Pin configuration

The PF240D25 manufactured by Sensata-Crydom meets all substitution criteria and is identified as a direct equivalent part.

Parameter Comparison

Engineering Selection Recommendations

The PF240D25 is the direct functional equivalent for CPF240D25 replacement applications. Both components share identical electrical specifications and mechanical packaging. The PF240D25 holds active product status with ROHS3 compliance certification, whereas the CPF240D25 is obsolete. For new designs and ongoing production requirements, the PF240D25 is the appropriate selection. Both parts maintain REACH Unaffected status and EAR99 export classification. The PF240D25 is available in bulk packaging with significantly higher inventory availability (20,099 units) compared to the CPF240D25 (723 units).

Frequently Asked Questions (FAQ)

Q: Can the PF240D25 directly replace the CPF240D25 in existing applications?

A: Yes. The PF240D25 maintains identical electrical ratings (25A load current, 12-280V output, 3-15VDC input), circuit configuration (SPST-NO), output type (AC zero-cross), and physical packaging (4-SIP through-hole with PC pins). No circuit modifications are required.

Q: What is the difference between the CPF240D25 and PF240D25?

A: Both components are manufactured by Sensata Technologies entities and share identical functional specifications. The primary differences are product status (CPF240D25 is obsolete; PF240D25 is active), RoHS compliance level (PF240D25 is ROHS3 compliant), and inventory availability.

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 footprint compatibility is confirmed.

Q: Which part should be selected for new designs?

A: The PF240D25 should be selected for all new designs. It maintains active product status and full compliance certifications, ensuring long-term availability and support.

Q: What compliance certifications apply to both parts?

A: Both the CPF240D25 and PF240D25 are REACH Unaffected and classified as EAR99 for export purposes. The PF240D25 additionally holds ROHS3 compliance certification.
