Key Parameters

Substitute Part Grouping Explanation

Substitution of the AFBR-703SDDZ is determined by strict equivalence across the following critical parameters:

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

The substitute part AFBR-703SDDZ-C, manufactured by ProLabs, meets all critical electrical and mechanical parameters required for direct substitution in systems designed for the original AFBR-703SDDZ module.

Parameter Comparison

Engineering Selection Recommendations

The AFBR-703SDDZ-C serves as the designated substitute for the obsolete AFBR-703SDDZ. The substitute maintains compatibility across wavelength, connector type, and mounting form factor. The substitute part carries active product status and RoHS compliance certification, providing advantages for new system designs and long-term component availability.

Selection of the AFBR-703SDDZ-C is appropriate for applications requiring direct replacement of the original Broadcom module in existing 850nm, 10 Gigabit Ethernet infrastructure.

Frequently Asked Questions (FAQ)

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

A: Yes. Both modules share identical wavelength (850nm), connector type (LC), and mounting form factor (Pluggable, SFP+), meeting the core substitution criteria for 10 Gigabit Ethernet applications.

Q: What is the significance of the AFBR-703SDDZ being classified as obsolete?

A: Obsolete status indicates the original manufacturer has discontinued production. The AFBR-703SDDZ-C, with active product status, provides continued availability for component procurement and system maintenance.

Q: Are there packaging differences between the main part and substitute?

A: The AFBR-703SDDZ-C is supplied in retail package format, whereas packaging information for the original part was not specified in the provided data.

Q: What does RoHS compliance on the substitute part indicate?

A: RoHS compliance on the AFBR-703SDDZ-C confirms the module meets Restriction of Hazardous Substances regulations, relevant for applications subject to environmental compliance requirements.

Q: Are the electrical specifications identical between both modules?

A: The substitute part is documented as compatible with the original AFBR-703SDDZ specification. Complete electrical parameter alignment is confirmed by the manufacturer compatibility designation.
