Phoenix Contact 2901788 Fiber Optic Connector Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 2901788 is a duplex fiber optic coupler designed for SC receptacle-to-SC receptacle panel mount applications with flange and snap-in mounting. This component functions as an adapter for singlemode and multimode fiber optic connections in industrial and telecommunications environments.

The 2901788 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system compatibility and ensure continued availability for maintenance, repair, and new installations where this connector type is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 2901788 is determined by the following critical parameters:

Primary Substitution Criteria:

• Coupler type (adapter function)
• Duplex configuration
• Panel mount, flange mounting interface
• SC or SCD receptacle connector compatibility
• Plastic housing material
• UL94 V-0 flammability rating
• IP20 ingress protection
• RoHS compliance

The Phoenix Contact 1208088 qualifies as a substitute based on matching coupler functionality, duplex configuration, panel mount flange design, plastic housing, UL94 V-0 rating, IP20 protection, and RoHS compliance. The 1208088 uses SCD (SC Duplex) receptacles, which are mechanically and optically compatible with SC duplex applications in panel mount configurations.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1208088 is the designated manufacturer substitute for the obsolete 2901788. Both components share identical core specifications for coupler functionality, duplex operation, panel mount flange design, plastic housing, UL94 V-0 flammability compliance, IP20 ingress protection, and RoHS compliance.

The 1208088 maintains active product status, ensuring ongoing availability and support. The operating temperature range of the 1208088 (-20°C to 70°C) is narrower than the 2901788 (-40°C to 80°C); applications requiring the full extended temperature range of the original part should be evaluated against actual system requirements.

Both parts are certified to UL94 V-0 flammability standards and comply with RoHS regulations, meeting industrial safety and environmental requirements.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1208088 directly replace the 2901788 in existing installations?

A: Yes. Both parts are duplex fiber optic couplers with panel mount flange design, plastic housing, and identical safety certifications (UL94 V-0, IP20, RoHS compliant). The 1208088 is the active substitute designated by Phoenix Contact for the obsolete 2901788.

Q: What is the difference between SC and SCD receptacle connectors?

A: SCD (SC Duplex) is the duplex variant of the SC connector standard. Both SC and SCD receptacles are mechanically and optically compatible in duplex panel mount coupler applications. The 1208088 uses SCD receptacles, which are standard for duplex fiber optic coupler configurations.

Q: Are there temperature range differences between these parts?

A: Yes. The 2901788 operates from -40°C to 80°C, while the 1208088 operates from -20°C to 70°C. For applications requiring operation below -20°C or above 70°C, the original 2901788 specifications should be verified against actual system requirements.

Q: What is the packaging difference between these parts?

A: The 2901788 was supplied without specified packaging designation. The 1208088 is supplied in bulk packaging. Both parts are available in new original condition with current inventory.

Q: Are both parts RoHS compliant?

A: Yes. Both the 2901788 and 1208088 are RoHS compliant and carry UL94 V-0 flammability ratings, meeting industrial safety and environmental standards.
