Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the SFP-XSM-LC-40K is determined by the following critical parameters: data rate, connector type, and mounting form factor. These parameters establish the physical and electrical interface requirements within host equipment.

The SFP-XSM5-LCI-40K is identified as a manufacturer-recommended substitute. Both components share identical data rate specifications (10Gbps) and mounting type (Pluggable, SFP+), ensuring mechanical and electrical interface compatibility. However, the substitute part operates at 1550nm wavelength with LC Duplex connector configuration and is designated for general-purpose applications rather than Ethernet-specific use. The substitute maintains active product status, providing continued availability and support.

Engineering Selection Recommendations

The SFP-XSM5-LCI-40K is designated as the manufacturer-recommended substitute for the obsolete SFP-XSM-LC-40K. Selection of the substitute component is supported by matching data rate and mounting specifications, which establish compatibility with host SFP+ port interfaces. Both components maintain REACH Unaffected compliance status.

The transition from the main part to the substitute involves wavelength and connector configuration changes. The substitute operates at 1550nm with LC Duplex connector versus the original 1310nm with LC connector. These differences require validation against specific system optical path requirements and connector interface specifications within the target application environment.

The active product status of the substitute ensures ongoing manufacturer support, availability, and compliance with current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: What determines whether the SFP-XSM5-LCI-40K can substitute for the SFP-XSM-LC-40K?

A: Substitution compatibility is established through matching data rate (10Gbps) and mounting form factor (Pluggable, SFP+). These parameters ensure the substitute component physically and electrically interfaces with host equipment designed for the original part.

Q: How do wavelength differences affect substitution?

A: The main part operates at 1310nm while the substitute operates at 1550nm. Wavelength selection is application-specific and depends on the optical infrastructure, fiber type, and system design. Wavelength compatibility must be verified against the complete optical link configuration.

Q: What is the significance of the connector type change from LC to LC Duplex?

A: The connector type change represents a physical interface modification. LC Duplex configuration differs from standard LC connector geometry. Connector compatibility must be confirmed with the host equipment port specifications before implementation.

Q: Why is the main part classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production and support for the SFP-XSM-LC-40K. The substitute part maintains active status, ensuring continued availability and manufacturer support.

Q: Are both components REACH compliant?

A: Both the main part and substitute are designated as REACH Unaffected, indicating compliance with REACH regulatory requirements.

Q: What inventory considerations apply to these components?

A: The main part has 1102 units in stock while the substitute has 1049 units available. Both are listed as new original inventory from the manufacturer.
