Key Parameters

Substitute Part Grouping Explanation

Substitution of the HFBR-2115TZ is determined by compatibility across the following critical parameters:

• Data rate capability (minimum 125MBd required)
• Supply voltage range overlap or compatibility
• Minimum receivable power performance
• Supply current requirements
• Moisture sensitivity level
• Regulatory compliance status

The HFBR-2316TZ qualifies as a substitute based on these criteria. While it operates at a higher data rate (155Mbps), it maintains compatibility with the electrical and environmental specifications of the original component and is manufactured by the same supplier.

Parameter Comparison

Engineering Selection Recommendations

The HFBR-2316TZ is available as an active product from Broadcom Limited, whereas the HFBR-2115TZ is obsolete. Both components maintain REACH Unaffected status and identical Moisture Sensitivity Level ratings. The HFBR-2316TZ demonstrates superior performance characteristics, including higher minimum receivable power (-45dBm versus -34.5dBm) and significantly reduced supply current (15 mA versus 82 mA). The supply voltage range of the HFBR-2316TZ (4.75V ~ 5.25V) is a subset of the HFBR-2115TZ range, requiring verification of system voltage regulation to ensure compatibility in existing designs.

Frequently Asked Questions (FAQ)

Q: Can the HFBR-2316TZ directly replace the HFBR-2115TZ in existing designs?

A: The HFBR-2316TZ is electrically compatible with the HFBR-2115TZ for general-purpose fiber optic receiver applications. However, the narrower supply voltage range (4.75V ~ 5.25V) of the HFBR-2316TZ must be verified against your system's voltage regulation specifications before implementation.

Q: What are the key differences between these two components?

A: The HFBR-2316TZ operates at a higher data rate (155Mbps versus 125MBd), provides improved sensitivity (-45dBm versus -34.5dBm), and consumes significantly less supply current (15 mA versus 82 mA). Both components share identical Moisture Sensitivity Level ratings and REACH compliance status.

Q: Why is the HFBR-2115TZ listed as obsolete?

A: The HFBR-2115TZ is classified as obsolete by the manufacturer. The HFBR-2316TZ is the active product offering from Broadcom Limited for fiber optic receiver applications in this performance class.

Q: Are there packaging differences between these parts?

A: The HFBR-2316TZ is supplied in Tube packaging. Packaging specifications for the HFBR-2115TZ were not provided in the reference data.

Q: Do both components meet the same regulatory requirements?

A: Both the HFBR-2115TZ and HFBR-2316TZ maintain REACH Unaffected status and are manufactured by Broadcom Limited, ensuring consistent regulatory compliance for applications requiring these certifications.
