Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AFBR-703ASDZ is determined by strict alignment of the following critical parameters:

• Wavelength: 850nm (multimode short-range operation)
• Data Rate: 10.312Gbd (10 Gigabit Ethernet SR specification)
• Connector Type: LC Duplex (physical interface requirement)
• Mounting Type: Pluggable, SFP+ (form factor and slot compatibility)
• Supply Voltage: 3.3V (electrical compatibility)
• Application: Ethernet (protocol compatibility)

The identified substitute part AFBR-703ASDZ-C meets all critical electrical and mechanical parameters required for direct substitution in systems designed for the original AFBR-703ASDZ module.

Engineering Selection Recommendations

The AFBR-703ASDZ-C is a direct functional equivalent suitable for replacement applications. Key considerations for selection:

• Product Status: The original AFBR-703ASDZ is obsolete. The AFBR-703ASDZ-C maintains active product status, ensuring ongoing availability and support.
• Compliance: The substitute part is RoHS compliant, whereas the original is RoHS non-compliant. Systems requiring RoHS compliance should prioritize the AFBR-703ASDZ-C.
• Electrical Compatibility: Both parts operate at identical wavelength (850nm), data rate (10.312Gbd), connector type (LC), and mounting configuration (SFP+), ensuring seamless integration into existing 10 Gigabit Ethernet infrastructure.
• Inventory Availability: The AFBR-703ASDZ-C is available in significantly higher quantities (40,714 units) compared to the original part (2,228 units).

Frequently Asked Questions (FAQ)

Q: Can the AFBR-703ASDZ-C be used as a direct replacement for the AFBR-703ASDZ?

A: Yes. Both modules share identical critical parameters: 850nm wavelength, 10.312Gbd data rate, LC duplex connectors, and SFP+ form factor. The AFBR-703ASDZ-C is designed for direct substitution in 10 Gigabit Ethernet SR applications.

Q: What is the difference in RoHS compliance between these parts?

A: The original AFBR-703ASDZ is RoHS non-compliant, while the AFBR-703ASDZ-C is RoHS compliant. Systems subject to RoHS regulations should use the compliant substitute part.

Q: Are there any packaging differences between the original and substitute?

A: The original AFBR-703ASDZ uses standard packaging, while the AFBR-703ASDZ-C is supplied in retail packaging. Both maintain identical SFP+ form factor and connector specifications for equipment compatibility.

Q: Why is the original AFBR-703ASDZ classified as obsolete?

A: Product obsolescence reflects end-of-life status from the original manufacturer. The AFBR-703ASDZ-C maintains active status, providing continued availability for replacement and new system deployments.

Q: What applications are supported by these transceiver modules?

A: Both modules are designed for 10 Gigabit Ethernet short-range (SR) applications using 850nm multimode fiber, typical in data center and enterprise network environments.
