Phoenix Contact 1411053 Fiber Optic Connector LC Duplex 125µm - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1411053 is a fiber optic plug connector with LC duplex configuration designed for singlemode applications with 9µm core diameter and 125µm cladding diameter. This connector features a blue housing with white boot, latch lock fastening, and free hanging in-line mounting. The product is classified as obsolete, making identification of functionally equivalent active alternatives necessary for ongoing procurement and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 1089520 qualifies as a direct substitute for the 1411053 based on the following critical parameters that determine functional compatibility:

• Connector Style & Type: Both are LC duplex plug connectors
• Fiber Specifications: Both support singlemode operation with 9µm core and 125µm cladding diameter
• Fastening & Mounting: Both use latch lock fastening and free hanging in-line mounting
• Housing & Color: Both feature blue housing with white boot and IP20 ingress protection
• Electrical Classification: Both carry identical ECCN (EAR99) and HTSUS (8536.70.0000) codes

The 1089520 differs in cable diameter accommodation (2.0mm–2.2mm versus 3.0mm), operating temperature range (-25°C to 70°C versus -10°C to 60°C), and product status (active versus obsolete). These differences do not prevent substitution when cable diameter compatibility is verified for the specific application.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1089520 is the recommended substitute for the obsolete 1411053. Both connectors meet identical fiber optic specifications for singlemode LC duplex applications and carry equivalent regulatory classifications (EAR99, HTSUS 8536.70.0000).

The 1089520 offers the advantage of active product status with extended availability and ROHS3 compliance, which supersedes the RoHS compliance of the 1411053. The wider operating temperature range (-25°C to 70°C) of the 1089520 provides greater environmental flexibility compared to the 1411053 (-10°C to 60°C).

Cable diameter compatibility must be confirmed for the specific installation. The 1411053 accommodates 3.0mm cable diameter, while the 1089520 is specified for 2.0mm to 2.2mm cable diameter. If the existing system uses 3.0mm cable, mechanical adaptation or cable replacement may be required.

Frequently Asked Questions (FAQ)

Q: Can the 1089520 directly replace the 1411053 in existing installations?

A: The 1089520 is functionally equivalent for fiber optic singlemode LC duplex applications. Substitution is valid when the cable diameter of 2.0mm to 2.2mm is compatible with the installation. If the system uses 3.0mm cable, mechanical compatibility must be assessed.

Q: What is the significance of the product status change from obsolete to active?

A: The 1411053 is classified as obsolete, indicating discontinued production and limited future availability. The 1089520 is active, ensuring ongoing supply, technical support, and compliance with current manufacturing standards.

Q: Are there compliance differences between the two connectors?

A: Both connectors carry identical ECCN (EAR99) and HTSUS (8536.70.0000) classifications. The 1089520 meets ROHS3 compliance, which represents the current regulatory standard and supersedes the RoHS compliance of the 1411053.

Q: How do the operating temperature ranges differ?

A: The 1411053 operates from -10°C to 60°C, while the 1089520 operates from -25°C to 70°C. The 1089520 provides a wider temperature envelope suitable for more demanding environmental conditions.

Q: What packaging options are available?

A: The 1411053 packaging specification is not provided. The 1089520 is supplied in bulk packaging. Confirm packaging requirements with procurement specifications.
