Substitute Part Grouping Explanation

Substitute parts for the AFCT-57F3TMZ are identified based on the following criteria:

Manufacturer-Recommended Substitute: AFCT-57G5MZ represents the direct manufacturer upgrade path, maintaining the Broadcom Limited product line while advancing to 32G data rate capability with enhanced specifications.

Similar Substitute: AFCT-57F3TMZ-C, manufactured by ATGBICS, provides functional equivalence at the original 16Gbps data rate specification, offering compatibility with systems requiring the legacy performance tier.

Key Parameters Determining Substitution:

• Connector Type (LC-based interfaces)
• Mounting Type (Pluggable SFP+ form factor)
• Wavelength (1310nm optical specification)
• Voltage Supply Range (3.1V–4.6V compatibility window)
• RoHS and environmental compliance status

Engineering Selection Recommendations

For Broadcom Product Line Continuity: Select AFCT-57G5MZ when system architecture supports 28.05Gbps data rates. This part maintains manufacturer lineage (Broadcom Limited, AFCT series), active product status, and ROHS3 compliance. The higher data rate provides forward compatibility with next-generation infrastructure requirements.

For Legacy 16Gbps System Compatibility: Select AFCT-57F3TMZ-C when system specifications mandate 16Gbps operation. This part delivers equivalent performance at the original data rate tier, maintains active product status, and provides RoHS compliance with extended inventory availability.

Both substitute parts maintain 1310nm wavelength specification, LC-based connector architecture, and SFP+ pluggable form factor, ensuring mechanical and optical compatibility with systems designed for the AFCT-57F3TMZ.

Frequently Asked Questions (FAQ)

Q: Can AFCT-57G5MZ be used as a direct replacement for AFCT-57F3TMZ?

A: AFCT-57G5MZ is mechanically and optically compatible (LC Duplex connector, 1310nm wavelength, SFP+ form factor). However, the 28.05Gbps data rate exceeds the original 16G specification. Compatibility depends on system hardware capability to support the higher data rate. Verify host equipment specifications before deployment.

Q: What is the difference between AFCT-57G5MZ and AFCT-57F3TMZ-C?

A: AFCT-57G5MZ operates at 28.05Gbps (manufacturer-recommended upgrade), while AFCT-57F3TMZ-C maintains 16Gbps operation (legacy equivalent). Both use 1310nm wavelength and SFP+ form factor. AFCT-57G5MZ is Broadcom-manufactured; AFCT-57F3TMZ-C is ATGBICS-manufactured. Select based on system data rate requirements and manufacturer preference.

Q: Are voltage supply ranges compatible across all three parts?

A: AFCT-57F3TMZ voltage specification is not provided. AFCT-57G5MZ operates at 3.1V–4.6V; AFCT-57F3TMZ-C operates at 3.3V–4.6V. Both ranges overlap at 3.3V–4.6V. Verify host power supply specifications to ensure compatibility with selected substitute.

Q: Why is AFCT-57F3TMZ classified as obsolete?

A: Broadcom Limited has transitioned this product to end-of-life status. AFCT-57G5MZ represents the active product line continuation with enhanced specifications. For new designs, AFCT-57G5MZ is the recommended path; for legacy system support, AFCT-57F3TMZ-C provides equivalent 16Gbps functionality.

Q: Are all substitute parts RoHS compliant?

A: Yes. AFCT-57F3TMZ and AFCT-57G5MZ are ROHS3 Compliant. AFCT-57F3TMZ-C is RoHS Compliant. Both compliance levels meet current environmental and regulatory requirements for electronic component deployment.
