Key Parameters

Substitute Part Grouping Explanation

Substitution of the M/DF-8-SC is determined by the following critical parameters:

• Functional Type: Multiplexer/Demultiplexer (Mux/Demux) capability
• Wavelength Management: CWDM 8-channel configuration
• Connector Interface: SC connector compatibility for optical signal transmission
• Moisture Sensitivity: MSL rating of 1 (Unlimited) for storage and handling
• Product Availability: Active status to ensure ongoing supply and support

The FWSF-M/D-8 substitute part maintains functional equivalence through identical Mux/Demux classification and 8-channel wavelength division capability. While the substitute introduces dual connector options (SC/PC and LC/PC), the SC/PC configuration provides direct compatibility with the original M/DF-8-SC interface specification.

Engineering Selection Recommendations

The FWSF-M/D-8 is the manufacturer-recommended substitute for the obsolete M/DF-8-SC. Selection of this alternative is supported by:

• Manufacturer Endorsement: Finisar Corporation designates FWSF-M/D-8 as the direct replacement
• Active Product Status: The substitute maintains current manufacturing and supply chain support
• Compliance Alignment: Both parts share identical MSL ratings, ensuring equivalent handling and storage requirements
• Connector Compatibility: SC/PC connector option in the substitute provides direct interface compatibility with existing M/DF-8-SC installations
• RoHS Compliance: The substitute meets RoHS requirements, supporting modern regulatory standards

Frequently Asked Questions (FAQ)

Q: Can the FWSF-M/D-8 directly replace the M/DF-8-SC in existing systems?

A: Yes. The FWSF-M/D-8 provides SC/PC connector configuration that is directly compatible with M/DF-8-SC installations. Both components maintain identical MSL ratings and Mux/Demux functionality for 8-channel wavelength division applications.

Q: What is the significance of the dual connector options (SC/PC and LC/PC) in the substitute part?

A: The FWSF-M/D-8 offers flexibility through multiple connector interface options. For direct replacement of the M/DF-8-SC, the SC/PC configuration should be specified to ensure seamless integration with existing fiber optic infrastructure.

Q: Are there any differences in handling or storage requirements between the main part and substitute?

A: No. Both the M/DF-8-SC and FWSF-M/D-8 share MSL rating 1 (Unlimited), indicating identical moisture sensitivity and storage condition requirements.

Q: Why is the M/DF-8-SC classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. The FWSF-M/D-8 represents the current-generation equivalent, ensuring access to supported, actively manufactured components.

Q: What export control classifications apply to these components?

A: The M/DF-8-SC carries ECCN 5A991B4A, while the FWSF-M/D-8 carries ECCN 5A991B5A. Both classifications reflect optical multiplexing/demultiplexing technology subject to export control regulations.
