Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1089520 is the direct substitute for the obsolete 1411299 based on functional equivalence across all critical fiber optic connector parameters. The 1089520 maintains identical LC duplex singlemode specifications with matching housing and boot colors, fastening mechanisms, and ingress protection ratings.

The 1089520 offers enhanced compliance through ROHS3 certification compared to the RoHS Compliant status of the 1411299. The wider operating temperature range (-25°C to 70°C versus -10°C to 60°C) and specified mating cycle rating of 500 cycles provide additional performance documentation for the active part.

Cable diameter compatibility is maintained within standard fiber optic specifications, with the 1089520 accommodating 2.0mm–2.2mm diameter cables compared to the 3.0mm specification of the 1411299. Both parts share identical ECCN and HTSUS classifications, ensuring consistent regulatory treatment.

Frequently Asked Questions (FAQ)

Q: Can the 1089520 directly replace the 1411299 in existing installations?

A: Yes. Both connectors share identical LC duplex singlemode specifications with 9µm core and 125µm cladding diameters, matching housing colors, latch lock fastening, and IP20 ingress protection. The functional fiber optic interface is equivalent.

Q: What is the significance of the cable diameter difference between 3.0mm and 2.0mm–2.2mm?

A: The cable diameter specification indicates the outer jacket diameter of the fiber optic cable. The 1089520 accommodates a narrower cable range (2.0mm–2.2mm) compared to the 1411299 (3.0mm). Cable selection must match the connector specification for proper strain relief and mechanical fit.

Q: Why is the 1411299 listed as obsolete?

A: Product obsolescence indicates that the manufacturer has discontinued production. The 1089520 is the active equivalent part available for new procurement and ongoing system support.

Q: Are there compliance differences between the two parts?

A: The 1411299 carries RoHS Compliant status, while the 1089520 carries ROHS3 Compliant status. ROHS3 represents an updated compliance standard. Both parts meet RoHS requirements; the 1089520 meets the more recent standard.

Q: What is the operating temperature range difference?

A: The 1411299 operates from -10°C to 60°C, while the 1089520 operates from -25°C to 70°C. The 1089520 provides a wider operational envelope, suitable for applications requiring extended temperature performance.

Q: Is the 1089520 available in bulk packaging?

A: Yes. The 1089520 is available in bulk packaging with 629 pieces in current inventory, compared to the 1411299 which is obsolete with 936 pieces remaining in stock.
