FTLF8519P2BCL Equivalent & Substitute Parts

Part Overview

The FTLF8519P2BCL is a transceiver module manufactured by Finisar Corporation, designed for Ethernet applications operating at 2.125Gbps with 850nm wavelength. This SFP (Small Form-factor Pluggable) module features LC duplex connectivity and operates within a 3V to 3.6V supply voltage range. The product is currently classified as obsolete, making identification of compatible substitute parts essential for system maintenance and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FTLF8519P2BCL is determined by strict alignment of the following critical parameters:

• Data Rate: 2.125Gbps (exact match required)
• Wavelength: 850nm (exact match required)
• Connector Type: LC Duplex (exact match required)
• Mounting Type: Pluggable, SFP (exact match required)
• Voltage - Supply: Compatible range (3V ~ 3.6V for main part; 3.3V for substitute falls within acceptable operating envelope)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The FTLF8519P3BNL meets all substitution criteria. While manufactured by Coherent rather than Finisar, it maintains identical data rate, wavelength, connector type, and mounting specifications. The supply voltage of 3.3V for the substitute part is compatible with the main part's 3V to 3.6V operating range.

Parameter Comparison

Engineering Selection Recommendations

The FTLF8519P3BNL is a direct substitute for the FTLF8519P2BCL based on electrical and mechanical parameter alignment. The substitute part carries Active product status, ensuring ongoing availability and support compared to the obsolete main part. The FTLF8519P3BNL is ROHS3 compliant and REACH unaffected, providing regulatory compliance advantages for new system designs and procurement cycles. The substitute part is available in Tray packaging with 1600 units in current inventory.

Frequently Asked Questions (FAQ)

Q: Can the FTLF8519P3BNL be used as a direct replacement for the FTLF8519P2BCL?

A: Yes. Both parts operate at identical data rates (2.125Gbps), wavelengths (850nm), and use the same LC duplex connector and SFP form factor. The supply voltage of 3.3V for the substitute falls within the 3V to 3.6V operating range of the main part.

Q: What is the difference in application scope between these parts?

A: The FTLF8519P2BCL is specified for Ethernet applications, while the FTLF8519P3BNL is designated for general purpose use. General purpose classification indicates broader compatibility across multiple system types and protocols operating at the specified data rate and wavelength.

Q: Why is the main part listed as obsolete?

A: Obsolete status indicates the FTLF8519P2BCL is no longer manufactured or supported by Finisar Corporation. The FTLF8519P3BNL, with Active product status, represents the current available alternative for equivalent functionality.

Q: Are there packaging differences between these parts?

A: The FTLF8519P2BCL packaging is not specified in available documentation. The FTLF8519P3BNL is supplied in Tray packaging. Confirm packaging requirements with your procurement specifications.

Q: What compliance certifications apply to the substitute part?

A: The FTLF8519P3BNL is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component manufacturing and distribution.
