AFCT-5179AZ Equivalent & Substitute Parts

Part Overview

The AFCT-5179AZ is a transceiver module manufactured by Broadcom Limited, designed for Ethernet applications operating at 125MBd data rate with 1300nm wavelength. This duplex SC connector module supports dual voltage operation (3.3V and 5V) and features through-hole mounting. The product is currently classified as obsolete, making identification of compatible substitute parts essential for system maintenance, legacy equipment support, and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AFCT-5179AZ are identified based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

• Data Rate: 125MBd (125Mbps equivalent)
• Wavelength: 1300nm
• Connector Type: SC
• Mounting Type: Through Hole
• Voltage Supply: Matching voltage configuration (3.3V or 5V)

The AFCT-5179AZ supports both 3.3V and 5V operation. Substitute parts are available as voltage-specific variants: AFCT-5179AZ-3.3V-C for 3.3V applications and AFCT-5179AZ-5V-C for 5V applications. Both substitutes are manufactured by ATGBICS and maintain identical optical and mechanical specifications to the original part.

Parameter Comparison

Engineering Selection Recommendations

Selection between substitute parts depends on the voltage requirement of the target application:

For 3.3V Systems: Use AFCT-5179AZ-3.3V-C. This substitute maintains active product status with ATGBICS, ensuring ongoing availability and support. RoHS compliance is confirmed, and REACH status remains unaffected.

For 5V Systems: Use AFCT-5179AZ-5V-C. This substitute is actively manufactured and distributed, providing equivalent electrical and optical performance at 5V supply voltage. Compliance certifications match regulatory requirements.

Both substitutes are manufactured by ATGBICS and carry active product status, distinguishing them from the obsolete Broadcom original. Inventory availability for both variants is substantial (8710 Pcs and 8664 Pcs respectively), supporting immediate procurement for replacement applications.

Frequently Asked Questions (FAQ)

Q: Can AFCT-5179AZ-3.3V-C and AFCT-5179AZ-5V-C be used interchangeably?

A: No. These parts are voltage-specific. AFCT-5179AZ-3.3V-C operates at 3.3V supply voltage, while AFCT-5179AZ-5V-C operates at 5V. Selection must match the system voltage requirement. Using an incorrect voltage variant will result in improper module operation or damage.

Q: What is the difference between the original AFCT-5179AZ and the substitute parts?

A: The original AFCT-5179AZ is obsolete and supports dual voltage operation (3.3V and 5V). The substitutes are voltage-specific variants manufactured by ATGBICS with active product status. All three parts share identical optical specifications (125MBd, 1300nm), connector type (SC), and mounting configuration (through hole).

Q: Are the substitute parts compatible with existing PCB designs for the AFCT-5179AZ?

A: Yes. Both substitute parts maintain identical SC connector type and through-hole mounting configuration. Mechanical and electrical interfaces are compatible with designs originally specified for the AFCT-5179AZ, provided the correct voltage variant is selected for the application.

Q: What is the packaging difference between the original and substitute parts?

A: The original AFCT-5179AZ is supplied with "-" packaging designation. Substitute parts are supplied in Tray packaging. This difference affects handling and storage procedures but does not impact functional performance or electrical characteristics.

Q: Are compliance certifications equivalent between the original and substitute parts?

A: Both substitute parts maintain RoHS compliance and REACH unaffected status, meeting the same regulatory requirements as the original AFCT-5179AZ. The original carries ROHS3 compliance, while substitutes carry RoHS compliance. Both satisfy current environmental and safety standards.
