Parameter Comparison

Engineering Selection Recommendations

Both CPDF12V and CPDFR12V are direct functional equivalents to the obsolete CPDFR12V-HF. Selection between these two active alternatives is based on the following factors:

Product Status: CPDF12V and CPDFR12V both maintain active product status with Comchip Technology, ensuring long-term availability and supply chain continuity compared to the obsolete CPDFR12V-HF.

Compliance & Certifications: All three parts maintain identical ROHS3 compliance, REACH unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating, confirming regulatory equivalence for applications requiring environmental compliance.

Packaging Availability: CPDF12V and CPDFR12V are supplied in Tape & Reel (TR) packaging, which is standard for high-volume production environments. The original CPDFR12V-HF packaging specification is not provided, but both substitutes support automated assembly processes.

Electrical & Mechanical Equivalence: All parameters including voltage ratings, current handling, clamping characteristics, capacitance, and physical package dimensions are identical across all three parts, confirming direct pin-for-pin and functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can CPDF12V and CPDFR12V be used interchangeably with CPDFR12V-HF?

A: Yes. Both CPDF12V and CPDFR12V maintain identical electrical specifications, package dimensions, and mounting characteristics. They are direct functional equivalents suitable for direct substitution in applications currently using CPDFR12V-HF.

Q: Why is CPDFR12V-HF classified as obsolete?

A: The CPDFR12V-HF has reached end-of-life status. CPDF12V and CPDFR12V are the active production alternatives from Comchip Technology with identical specifications and continued availability.
