Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1411052 is based on the following critical parameters that must remain consistent:

• Connector Style: LC
• Connector Type: Plug
• Simplex/Duplex Configuration: Duplex
• Mode: Multimode
• Fiber Core Diameter: 50µm
• Fiber Cladding Diameter: 125µm
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Latch Lock
• Ingress Protection: IP20
• Housing Material: Polybutylene Terephthalate (PBT)
• Manufacturer: Phoenix Contact

The Phoenix Contact 1089521 qualifies as a substitute part because it maintains all critical electrical and mechanical parameters. Variations in housing color (gray versus beige), boot color, cable diameter range compatibility (2.0mm ~ 3.0mm versus fixed 3.0mm), and extended operating temperature range do not affect functional interchangeability in multimode LC duplex fiber optic applications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1089521 is the designated substitute for the obsolete 1411052 part number. Both components maintain identical core specifications for LC duplex multimode fiber optic connectivity with 50µm core and 125µm cladding diameters. The 1089521 is currently in active production status, ensuring availability and supply chain continuity.

The 1089521 provides an extended operating temperature range (-25°C ~ 70°C versus -10°C ~ 60°C), which offers broader environmental compatibility. The cable diameter specification of 2.0mm ~ 3.0mm accommodates the original 3.0mm requirement while providing additional flexibility for alternative cable gauges. Both parts maintain RoHS compliance and identical ingress protection ratings.

Selection of the 1089521 eliminates obsolescence risk while preserving functional equivalence in multimode fiber optic duplex connector applications.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1089521 directly replace the 1411052 in existing installations?

A: Yes. Both connectors share identical LC duplex multimode specifications with 50µm core and 125µm cladding diameters, matching connector styles, plug types, latch lock fastening, and IP20 ingress protection ratings. The 1089521 is functionally equivalent for fiber optic signal transmission in multimode applications.

Q: What is the significance of the housing color difference between beige (1411052) and gray (1089521)?

A: Housing color is a cosmetic and organizational parameter that does not affect electrical or optical performance. Color coding may be used for system identification or inventory management but does not impact connector functionality or interchangeability.

Q: Why does the 1089521 specify a cable diameter range (2.0mm ~ 3.0mm) while the 1411052 specifies a fixed 3.0mm?

A: The 1089521 accommodates a broader range of cable diameters within the same connector housing. This flexibility allows the substitute part to work with the original 3.0mm cable specification and alternative cable gauges, enhancing system design flexibility without compromising performance.

Q: Does the extended operating temperature range of the 1089521 affect compatibility?

A: No. The extended range (-25°C ~ 70°C for 1089521 versus -10°C ~ 60°C for 1411052) represents an enhancement that maintains full compatibility with the original operating conditions. The substitute part operates reliably across the original temperature specification and beyond.

Q: Are there packaging differences between these parts?

A: The 1411052 was supplied with unspecified packaging, while the 1089521 is supplied in bulk packaging. Both parts are available in new original condition. Packaging format does not affect connector performance or interchangeability.

Q: Why is the 1411052 listed as obsolete?

A: The 1411052 has been discontinued by Phoenix Contact. The 1089521 is the active production equivalent that maintains all critical specifications for multimode LC duplex fiber optic applications, ensuring continued availability and supply chain support.
