Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AFBR-5103ATZ are identified based on the following critical parameters that determine functional compatibility:

• Data Rate: 100Mbps (must match)
• Wavelength: 1300nm (must match)
• Connector Type: ST (must match)
• Mounting Type: Through Hole (must match)
• Applications: General Purpose (must match)

The substitute parts listed maintain these core electrical and mechanical specifications. Voltage supply ranges may differ within acceptable operating parameters for the application category. Product status and compliance certifications are secondary factors that influence selection based on availability and regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

AFBR-5803ATZ (Broadcom Limited): This substitute is an active product from the original manufacturer with ROHS3 compliance. It maintains all critical electrical and mechanical parameters matching the AFBR-5103ATZ. The voltage supply range of 3.3V and 5V encompasses the original 4.75V to 5.25V specification. This part is recommended for applications requiring manufacturer continuity and regulatory compliance assurance.

AFBR-5103ATZ-C (ATGBICS): This substitute is an active product with RoHS compliance. It maintains all critical electrical and mechanical parameters. The voltage supply is specified as 3.3V, which differs from the original 4.75V to 5.25V range. This part is suitable for applications operating within the 3.3V supply voltage specification.

Frequently Asked Questions (FAQ)

Q: Can AFBR-5803ATZ directly replace AFBR-5103ATZ in existing designs?

A: Yes. Both parts share identical data rate (100Mbps), wavelength (1300nm), connector type (ST), and mounting type (through hole). The voltage supply range of AFBR-5803ATZ (3.3V, 5V) is compatible with systems designed for the original 4.75V to 5.25V specification.

Q: What is the primary difference between AFBR-5803ATZ and AFBR-5103ATZ-C?

A: Both are active substitutes with matching core specifications. AFBR-5803ATZ is manufactured by Broadcom Limited with ROHS3 compliance and MSL rating of 1. AFBR-5103ATZ-C is manufactured by ATGBICS with RoHS compliance and no MSL rating. AFBR-5803ATZ supports dual voltage (3.3V, 5V) while AFBR-5103ATZ-C operates at 3.3V only.

Q: Is the AFBR-5103ATZ-C suitable for 5V applications?

A: No. AFBR-5103ATZ-C is specified for 3.3V supply voltage only. For 5V applications, AFBR-5803ATZ is the appropriate substitute.

Q: Why is the original AFBR-5103ATZ obsolete?

A: Product obsolescence is determined by the manufacturer. Active substitutes with equivalent specifications are available to support continued system deployment and new designs.

Q: Are all substitute parts REACH compliant?

A: Yes. All listed substitutes maintain REACH Unaffected status, matching the original part's regulatory standing.
