Key Parameters

Substitute Part Grouping Explanation

Substitution of the HFBR-5701LP is determined by strict alignment of the following critical parameters:

• Data Rate: 1.25Gbd (equivalent to 1000Mbps for Gigabit Ethernet)
• Wavelength: 850nm (multimode fiber, short wavelength)
• Supply Voltage: 3.3V
• Connector Type: LC Duplex
• Mounting Type: Pluggable, SFP form factor
• Application Domain: Networking and Ethernet

The HFBR-5701LP-C, manufactured by ATGBICS, meets all critical substitution criteria. This part is designated as Avago Broadcom® Compatible, indicating functional equivalence within the specified parameter set. The substitute maintains identical data rate, wavelength, voltage, connector type, and form factor specifications.

Parameter Comparison

Engineering Selection Recommendations

The HFBR-5701LP-C is the designated substitute for the obsolete HFBR-5701LP based on the following engineering criteria:

• The substitute maintains full parameter alignment across all critical electrical and mechanical specifications
• The substitute is classified as Active product status, ensuring ongoing availability and supply chain continuity
• The HFBR-5701LP-C carries ECCN classification EAR99, compared to the original part's ECCN 5A991B4A, which may affect export compliance considerations
• Both parts operate at identical wavelength (850nm) and data rate (1.25Gbd/1000Mbps), ensuring functional compatibility in Gigabit Ethernet applications
• The substitute is supplied in Tray packaging, whereas the original packaging specification was not provided

Frequently Asked Questions (FAQ)

Q: Can the HFBR-5701LP-C directly replace the HFBR-5701LP in existing systems?

A: Yes. The HFBR-5701LP-C meets all critical substitution parameters: identical 850nm wavelength, 1.25Gbd/1000Mbps data rate, 3.3V supply voltage, LC duplex connector, and SFP form factor. Both parts are designed for Gigabit Ethernet applications.

Q: What is the significance of the "Broadcom® Compatible" designation?

A: This designation indicates that the HFBR-5701LP-C is engineered to provide functional equivalence with Broadcom's original HFBR-5701LP specification, ensuring compatibility with systems designed for the original part.

Q: Are there differences in compliance or certification between these parts?

A: The original HFBR-5701LP is RoHS non-compliant with ECCN 5A991B4A. The substitute HFBR-5701LP-C carries ECCN classification EAR99. Organizations must evaluate export control and environmental compliance requirements for their specific applications.

Q: Does the packaging difference (Tray vs. unspecified) affect compatibility?

A: Packaging affects handling, storage, and logistics but does not affect electrical or mechanical compatibility. The Tray packaging of the substitute is standard for SFP module distribution.

Q: Why is the original part classified as obsolete?

A: Broadcom has discontinued the HFBR-5701LP, making the HFBR-5701LP-C the active substitute for ongoing procurement and system maintenance.
