Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FTLF1326P3BTL are evaluated based on the following critical parameters that determine functional compatibility:

• Mounting Type & Form Factor: Pluggable SFP+ form factor ensures mechanical compatibility with existing SFP+ slots
• Connector Interface: LC duplex connectivity maintains optical path compatibility
• Voltage Supply: 3.3V operation ensures compatibility with host system power delivery
• Moisture Sensitivity Level: MSL 1 (Unlimited) indicates no moisture sensitivity constraints during storage or handling

The FTLX1370W4BTL meets these core compatibility criteria while offering enhanced data rate capability (10Gbps) and active product status, making it suitable for applications requiring higher bandwidth within the same mechanical and electrical envelope.

Engineering Selection Recommendations

The FTLX1370W4BTL serves as a direct substitute for the obsolete FTLF1326P3BTL based on matching electrical and mechanical specifications. Key selection factors include:

• Product Status: The FTLX1370W4BTL maintains active product status with ongoing manufacturer support, addressing the obsolescence of the original component
• Compliance: ROHS3 compliance of the substitute part aligns with current environmental and regulatory standards
• Form Factor Compatibility: Identical SFP+ pluggable form factor and LC duplex connector ensure drop-in compatibility with existing host equipment
• Electrical Compatibility: Matching 3.3V supply voltage and MSL 1 rating maintain compatibility with system power delivery and handling requirements
• Data Rate Consideration: The 10Gbps capability of the substitute exceeds the 6.1Gbps requirement, providing bandwidth headroom for future system upgrades while remaining backward compatible with 6.1Gbps operation

Frequently Asked Questions (FAQ)

Q: Can the FTLX1370W4BTL directly replace the FTLF1326P3BTL in existing systems?

A: Yes. Both components share identical mounting type (Pluggable SFP+), connector interface (LC Duplex), and supply voltage (3.3V). The substitute will physically and electrically integrate into any SFP+ slot designed for the original part.

Q: What is the significance of the higher 10Gbps data rate on the substitute part?

A: The FTLX1370W4BTL operates at 10Gbps, exceeding the 6.1Gbps specification of the original part. This higher capability does not prevent substitution; the part will operate at the lower data rate if the host system is configured for 6.1Gbps operation. This provides design flexibility for future bandwidth requirements.

Q: Are there any handling or storage differences between these parts?

A: No. Both parts carry MSL 1 (Unlimited) rating, indicating identical moisture sensitivity characteristics. Standard handling and storage procedures apply equally to both components.

Q: Why is the FTLF1326P3BTL listed as obsolete?

A: Obsolescence reflects the manufacturer's discontinuation of production. The FTLX1370W4BTL, maintained in active status by Coherent, represents the current-generation equivalent with enhanced specifications and ongoing support.

Q: What compliance certifications should be considered for new designs?

A: The FTLX1370W4BTL carries ROHS3 compliance certification, meeting current environmental standards for new product designs and procurement. Original compliance status of the FTLF1326P3BTL is not specified in available documentation.
