Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SFP-1GBT-05 are identified based on strict electrical and mechanical compatibility criteria. The following parameters must match or be compatible:

• Data Rate: 1.25Gbps
• Voltage - Supply: 3.3V
• Connector Type: RJ45
• Mounting Type: Pluggable, SFP Copper
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The FCLF8522P2BTL from Coherent meets all these critical parameters and qualifies as a direct substitute. While the original part is designated for general-purpose applications and the substitute is specified for Ethernet applications, both operate within the same electrical and mechanical envelope, making them functionally interchangeable in systems requiring 1.25Gbps copper SFP transceiver modules.

Parameter Comparison

Engineering Selection Recommendations

The FCLF8522P2BTL is a qualified substitute for the SFP-1GBT-05. Selection should be based on the following factors:

• The substitute part maintains active product status, ensuring ongoing availability and supply chain continuity.
• Both parts carry identical ECCN and HTSUS classifications, confirming regulatory equivalence.
• The substitute part is supplied in Tray packaging, which may differ from the original part's packaging configuration. Verify packaging compatibility with your assembly and storage requirements.
• Both parts meet ROHS3 compliance and carry MSL 1 rating, confirming environmental and handling equivalence.

Frequently Asked Questions (FAQ)

Q: Can the FCLF8522P2BTL directly replace the SFP-1GBT-05 in existing systems?

A: Yes. Both parts share identical electrical specifications (1.25Gbps, 3.3V), connector type (RJ45), and mounting form factor (Pluggable SFP Copper). They are mechanically and electrically interchangeable.

Q: What is the difference between "General Purpose" and "Ethernet" application designations?

A: The application designation reflects the primary intended use case. Both parts operate at identical electrical parameters and are compatible with systems requiring 1.25Gbps copper SFP transceiver functionality.

Q: Does the packaging difference (Tray for the substitute) affect compatibility?

A: Packaging affects handling, storage, and assembly logistics but does not affect electrical or mechanical compatibility. Verify that Tray packaging meets your procurement and assembly requirements.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both parts are ROHS3 compliant and carry identical ECCN and HTSUS classifications, confirming regulatory equivalence for export and environmental compliance purposes.

Q: Why is the original part listed as obsolete?

A: Product obsolescence reflects manufacturer discontinuation decisions. The substitute part maintains active status, providing continued availability for replacement and new deployment applications.
