AFCT-5715LZ Equivalent & Substitute Parts

Part Overview

The AFCT-5715LZ is a transceiver module manufactured by Broadcom Limited, designed for Ethernet applications operating at 1.25Gbd with a 1310nm wavelength. This SFP (Small Form-factor Pluggable) module features LC duplex connectors and operates within a 3.14V to 3.47V supply voltage range. The product is currently classified as obsolete, making identification of equivalent and substitute parts essential for system maintenance, legacy system support, and component procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AFCT-5715LZ is determined by the following critical parameters:

• Data Rate: 1.25Gbd (Gigabit per second)
• Wavelength: 1310nm (Long wavelength, single-mode operation)
• Connector Type: LC Duplex
• Mounting Type: Pluggable, SFP form factor
• Voltage Supply Range: 3.14V ~ 3.47V

Substitute parts must maintain compatibility across these core electrical and mechanical specifications to ensure proper operation within existing system architectures. The identified substitute parts are grouped based on their alignment with these parameters.

Parameter Comparison

Engineering Selection Recommendations

AFCT-5715LZ-C is the primary substitute for the obsolete AFCT-5715LZ. Both parts operate at 1.25Gbps with 1310nm wavelength and LC duplex connectors in SFP form factor. The AFCT-5715LZ-C is manufactured by ATGBICS and maintains active product status with RoHS compliance. The voltage supply specification differs (5V versus 3.14V ~ 3.47V), requiring verification of system power delivery capability before deployment.

AFCT-725SMZ is not recommended as a direct substitute. Although manufactured by Broadcom Limited with ROHS3 compliance and 1310nm wavelength alignment, this part operates at 25Gbps data rate and uses SFP28 form factor, representing a significant performance and mechanical departure from the original AFCT-5715LZ specification. This part is classified as Last Time Buy, indicating limited future availability.

Frequently Asked Questions (FAQ)

Q: Can AFCT-725SMZ replace AFCT-5715LZ in existing systems?

A: No. The AFCT-725SMZ operates at 25Gbps versus the AFCT-5715LZ's 1.25Gbd specification and uses SFP28 form factor instead of SFP. These differences prevent direct substitution without system redesign.

Q: What is the primary concern when substituting AFCT-5715LZ with AFCT-5715LZ-C?

A: The voltage supply specification differs. AFCT-5715LZ operates at 3.14V ~ 3.47V, while AFCT-5715LZ-C requires 5V. System power delivery architecture must support the higher voltage requirement.

Q: Are both substitute parts RoHS compliant?

A: Yes. AFCT-5715LZ-C is RoHS Compliant, and AFCT-725SMZ is ROHS3 Compliant, meeting environmental regulatory requirements.

Q: Why is AFCT-5715LZ classified as obsolete?

A: Broadcom Limited has discontinued this product line. AFCT-5715LZ-C, offered by ATGBICS, represents the active equivalent for 1.25Gbps 1310nm SFP transceiver applications.

Q: What is the difference between SFP and SFP28 form factors?

A: SFP (Small Form-factor Pluggable) and SFP28 are distinct mechanical and electrical form factors. SFP28 supports higher data rates (up to 28Gbps) but is not backward compatible with standard SFP slots. Physical dimensions and connector specifications differ between the two.
