Engineering Selection Recommendations

The Phoenix Contact 1843813 is the designated substitute for the obsolete 1897267. Both components maintain identical electrical ratings (8A at 250V IEC, 8A at 300V UL) and mechanical compatibility through matching pitch, position count, and shrouded header design.

The primary distinction is termination methodology: the 1897267 uses press-fit termination, while the 1843813 requires solder attachment. This difference necessitates PCB design modification and assembly process adjustment. The 1843813 is currently in active production status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. Minor dimensional variations in contact tail length (0.004" difference) and insulation height (0.009" difference) fall within acceptable tolerance ranges for standard through-hole applications.

Frequently Asked Questions (FAQ)

Q: Can the 1843813 directly replace the 1897267 without PCB modification?

A: No. The 1897267 uses press-fit termination for direct PCB insertion, while the 1843813 requires solder attachment. PCB pad design and assembly process must be updated accordingly.

Q: Are the electrical ratings identical between these parts?

A: Yes. Both components are rated at 8A (IEC), 250V (IEC), 8A (UL), and 300V (UL). Electrical performance is equivalent.

Q: What is the significance of the contact tail length difference?

A: The 1897267 has a 0.138" (4.60mm) contact tail, while the 1843813 has a 0.134" (3.40mm) tail. This 0.004" difference is within standard PCB hole tolerance and does not affect functional compatibility for through-hole mounting.

Q: Does the insulation height difference impact mechanical fit?

A: The 1843813 insulation height is 0.009" greater than the 1897267. This minor difference does not affect standard mounting applications but should be considered in space-constrained designs.

Q: Why is the 1897267 listed as obsolete?

A: The 1897267 belongs to the COMBICON EMC series, which has been superseded by the active COMBICON MC series, represented by the 1843813.

Q: Is the 1843813 RoHS compliant?

A: Yes. The 1843813 carries ROHS3 compliance, meeting current regulatory requirements. The 1897267 is RoHS Compliant under the original directive.

Q: What packaging is available for the 1843813?

A: The 1843813 is supplied in bulk packaging, with 3200 pieces currently in stock.
