AFCT-57R5APZ Equivalent & Substitute Parts

Part Overview

The AFCT-57R5APZ is a transceiver module manufactured by Broadcom Limited, designed for general-purpose optical communication applications. This SFP-format module operates at 4.25Gbps with a 1310nm wavelength and requires 3.3V supply voltage. The product is currently classified as obsolete, making identification of compatible substitute parts essential for system maintenance and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AFCT-57R5APZ is determined by the following critical parameters:

• Data Rate: 4.25Gbps
• Wavelength: 1310nm
• Voltage - Supply: 3.3V
• Connector Type: LC (Duplex or standard)
• Mounting Type: Pluggable SFP or SFP+ format
• Applications: General Purpose

The substitute part AFCT-57R5APZ-C meets these core electrical and mechanical requirements, enabling functional equivalence in systems designed for the original component.

Parameter Comparison

Engineering Selection Recommendations

The AFCT-57R5APZ-C serves as the designated substitute for the obsolete AFCT-57R5APZ. Both components share identical electrical specifications: 4.25Gbps data rate, 1310nm wavelength, and 3.3V supply voltage. The substitute maintains active product status with ATGBICS as the manufacturer, ensuring ongoing availability and support.

The transition from SFP to SFP+ mounting format and the change from LC Duplex to LC connector type represent mechanical variations that must be verified for compatibility with the host system's transceiver slot and optical interface design. The substitute's REACH compliance status (EAR99) differs from the original (REACH Unaffected), which may affect regulatory considerations depending on application geography.

Frequently Asked Questions (FAQ)

Q: Can AFCT-57R5APZ-C be used as a direct replacement for AFCT-57R5APZ?

A: The AFCT-57R5APZ-C matches all critical electrical parameters (data rate, wavelength, supply voltage, and applications). However, the mounting type differs (SFP+ versus SFP) and connector configuration changes from LC Duplex to LC. Verify that your system's transceiver slot supports SFP+ modules and that the LC connector configuration is compatible with your optical infrastructure before substitution.

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

A: The original AFCT-57R5APZ is obsolete and no longer manufactured by Broadcom Limited. The AFCT-57R5APZ-C is actively produced by ATGBICS, ensuring component availability for future procurement and system maintenance.

Q: Are there differences in moisture sensitivity between the two parts?

A: The original part specifies MSL 1 (Unlimited), while the substitute lists MSL as Not Applicable. This difference reflects different manufacturing and packaging standards between the two manufacturers. Verify storage and handling requirements with ATGBICS documentation for the substitute part.

Q: What are the key parameters that determine substitution compatibility?

A: The primary compatibility parameters are data rate (4.25Gbps), wavelength (1310nm), supply voltage (3.3V), and general-purpose application classification. Mechanical factors including mounting type (SFP/SFP+) and connector type (LC Duplex/LC) must also be validated against your system specifications.
