Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AFCT-57F3TMZ-IBY are identified based on compatibility across the following critical parameters:

Primary Compatibility Criteria:

• Mounting Type: Pluggable, SFP+
• Connector Type: LC (duplex or single)
• Wavelength: 1310 nm
• Voltage Supply Range: Overlapping or compatible with 3.135 V – 3.465 V
• Applications: Fibre Channel or General Purpose

Substitution Logic:

The AFCT-57G5MZ (Broadcom Limited) qualifies as a manufacturer-recommended substitute. Although it operates at a higher data rate (28.05 Gbps versus 14.025 Gbps), it maintains the same wavelength (1310 nm), connector type (LC duplex), mounting type (SFP+), and compatible voltage supply range (3.1 V – 3.5 V). The higher data rate provides forward compatibility in systems capable of supporting increased throughput.

The AFCT-57F3TMZ-IBY-C (ATGBICS) qualifies as a similar substitute. It operates at 16 Gbps with 1310 nm wavelength, LC connector, and SFP+ mounting. The voltage supply is specified at 3.3 V, which falls within the acceptable range. This part is classified as active and maintains RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

AFCT-57G5MZ Selection:

The AFCT-57G5MZ is the manufacturer-recommended substitute and is classified as active. This part maintains Broadcom Limited manufacturing continuity and ROHS3 compliance. The higher data rate (28.05 Gbps) is backward compatible with systems designed for 14.025 Gbps operation. Voltage supply ranges overlap sufficiently (3.1 V – 3.5 V encompasses the original 3.135 V – 3.465 V specification). This part is suitable for direct replacement in Fibre Channel Link applications where the system supports the higher data rate capability.

AFCT-57F3TMZ-IBY-C Selection:

The AFCT-57F3TMZ-IBY-C is an active substitute manufactured by ATGBICS. It operates at 16 Gbps, positioned between the original 14.025 Gbps and the higher-rate alternative. The 3.3 V supply voltage is compatible with the original specification range. This part is designated for General Purpose applications and maintains RoHS compliance. Selection of this part is appropriate for systems requiring a data rate intermediate to the original specification.

Both substitute parts are active products with current manufacturing status, ensuring long-term availability and supply chain stability compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can the AFCT-57G5MZ operate in systems designed for the AFCT-57F3TMZ-IBY?

A: Yes. The AFCT-57G5MZ maintains compatibility across mounting type (SFP+), connector type (LC duplex), wavelength (1310 nm), and voltage supply range. The higher data rate (28.05 Gbps) is supported by systems capable of operating at the original 14.025 Gbps specification.

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

A: The AFCT-57G5MZ is manufactured by Broadcom Limited (original manufacturer) and operates at 28.05 Gbps. The AFCT-57F3TMZ-IBY-C is manufactured by ATGBICS and operates at 16 Gbps. Both maintain 1310 nm wavelength and SFP+ mounting compatibility. The AFCT-57G5MZ is designated as the manufacturer-recommended option.

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

A: Yes. The original part specifies 3.135 V – 3.465 V. The AFCT-57G5MZ operates at 3.1 V – 3.5 V, and the AFCT-57F3TMZ-IBY-C operates at 3.3 V. All three ranges are compatible for system integration.

Q: Does the connector type differ between substitutes?

A: The original AFCT-57F3TMZ-IBY and the AFCT-57G5MZ both specify LC duplex connectors. The AFCT-57F3TMZ-IBY-C specifies LC connector type. Both configurations are compatible with LC duplex infrastructure.

Q: What is the significance of the obsolete status of the original part?

A: The obsolete status indicates that the AFCT-57F3TMZ-IBY is no longer manufactured by Broadcom Limited. Both substitute parts are classified as active, ensuring continued availability and manufacturing support for new procurements and system maintenance.

Q: Are all substitute parts RoHS compliant?

A: Yes. The AFCT-57F3TMZ-IBY is ROHS3 compliant. The AFCT-57G5MZ is ROHS3 compliant. The AFCT-57F3TMZ-IBY-C is RoHS compliant. All parts meet regulatory requirements for hazardous substance restrictions.
