Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AFBR-5103PZ is determined by the following critical parameters:

• Data Rate: 100Mbps (required match)
• Connector Type: SC (required match)
• Mounting Type: Through Hole (required match)
• Wavelength: 1308nm nominal operation (1300nm acceptable within standard telecommunications tolerances)

The AFBR-5103PZ-C qualifies as a substitute based on matching data rate (100Mbps), connector type (SC), and mounting type (through hole). The wavelength specification of 1300nm represents standard telecommunications operating range compatibility with the original 1308nm specification.

Parameter Comparison

Engineering Selection Recommendations

The AFBR-5103PZ-C is available as an active product with current manufacturing support, addressing the obsolescence status of the original AFBR-5103PZ. Both components maintain REACH compliance status. The substitute part operates at 3.3V supply voltage, which differs from the original 4.75V to 5.25V specification and requires circuit-level voltage compatibility assessment during integration. The RoHS compliant status of the substitute part provides additional environmental compliance benefits for new implementations.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters for substituting the AFBR-5103PZ?

A: The data rate (100Mbps), connector type (SC), and mounting type (through hole) must remain constant. Wavelength operation within the 1300nm telecommunications band is acceptable for substitution purposes.

Q: Is the AFBR-5103PZ-C a direct pin-for-pin replacement?

A: Both components feature SC connectors and through-hole mounting. However, the supply voltage differs (3.3V versus 4.75V–5.25V), requiring verification of circuit compatibility before implementation.

Q: What is the significance of the product status change from Obsolete to Active?

A: The substitute part maintains active manufacturing status, ensuring continued availability and technical support for future procurement and system maintenance cycles.

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

A: Both components maintain REACH unaffected status. The substitute part carries RoHS compliance certification, which may be advantageous for applications with environmental compliance requirements.

Q: How does the wavelength difference (1308nm vs. 1300nm) affect compatibility?

A: Both wavelengths operate within the standard 1300nm telecommunications window. This difference falls within acceptable operating parameters for Ethernet transceiver applications at 100Mbps data rates.
