Engineering Selection Recommendations

The Phoenix Contact 1844265 serves as a direct functional substitute for the obsolete 1897144 based on the following engineering criteria:

Mechanical Compatibility: Both parts maintain identical 7-position configuration, 4.6mm pitch, 90° right-angle orientation, and through-hole mounting. Minor dimensional variations in contact tail length (0.138" vs. 0.134") and insulation height (0.276" vs. 0.285") fall within acceptable mechanical tolerances for standard PCB mounting applications.

Electrical Equivalence: The 1844265 meets or exceeds all electrical requirements of the 1897144. Both parts support 250 V (IEC) and 300 V (UL) voltage ratings. The 1844265 provides enhanced current capacity at 12A (IEC) compared to the 1897144's 8A (IEC), while maintaining 8A under UL specifications.

Compliance & Longevity: The 1844265 holds active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. Both parts feature identical UL94 V-0 flammability ratings and PBT housing material.

Termination Consideration: The primary difference is termination style—the 1897144 uses press-fit termination while the 1844265 uses solder termination. This difference requires PCB design verification to confirm compatibility with existing through-hole pad layouts and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 1844265 directly replace the 1897144 in existing designs?

A: Mechanical and electrical compatibility is confirmed. However, the termination style difference (press-fit vs. solder) requires verification that PCB pad specifications and assembly processes accommodate solder termination. Contact tail length and insulation height variations are within standard tolerances.

Q: What is the significance of the product status change from Obsolete to Active?

A: The 1844265's active status ensures continued manufacturing, availability, and technical support from Phoenix Contact. This eliminates supply chain risk associated with the obsolete 1897144.

Q: Are there compliance differences between the two parts?

A: Both parts meet UL94 V-0 flammability requirements and PBT housing specifications. The 1844265 carries ROHS3 compliance, representing a more current regulatory standard than the 1897144's RoHS compliance.

Q: Does the higher current rating of the 1844265 (12A IEC vs. 8A IEC) affect compatibility?

A: Higher current capacity is a non-limiting factor for substitution. The 1844265 can safely handle applications designed for the 1897144's 8A rating without degradation.

Q: What packaging differences exist between these parts?

A: The 1897144 is supplied in standard packaging, while the 1844265 is supplied in bulk packaging. Bulk packaging does not affect component functionality or electrical performance.

Q: Are there any series compatibility considerations?

A: The 1897144 belongs to the COMBICON EMC series, while the 1844265 belongs to the COMBICON MC series. Both are Phoenix Contact COMBICON family products with compatible mechanical and electrical interfaces.
