AFBR-725TMZ Equivalent & Substitute Parts

Part Overview

The AFBR-725TMZ is a SFP+ 25G SR transceiver module manufactured by Broadcom Limited, designed for high-speed Ethernet applications operating at 25.78125 Gbps over multimode fiber at 850nm wavelength. This module features LC duplex connectors and operates within a 3.1V to 3.5V supply voltage range.

The AFBR-725TMZ has reached obsolete product status. Identifying equivalent and substitute parts is necessary to maintain system compatibility and ensure continued availability for replacement, upgrade, or new deployment scenarios where this transceiver module is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AFBR-725TMZ is determined by strict alignment of the following critical electrical and mechanical parameters:

Electrical Parameters:

• Data Rate: 25.78125 Gbps
• Wavelength: 850 nm
• Voltage Supply Range: 3.1V ~ 3.5V
• Application: Ethernet

Mechanical Parameters:

• Connector Type: LC Duplex
• Mounting Type: Pluggable form factor
• RoHS Compliance: ROHS3 Compliant

The AFBR-735TMZ qualifies as a manufacturer-recommended substitute because it maintains identical electrical specifications (data rate, wavelength, voltage supply, and Ethernet application) and compatible mechanical characteristics (LC duplex connector, pluggable form factor, and ROHS3 compliance). While the AFBR-735TMZ uses an SFP28 form factor compared to the SFP form factor of the AFBR-725TMZ, both are pluggable transceiver modules with equivalent electrical performance parameters.

Parameter Comparison

Engineering Selection Recommendations

The AFBR-735TMZ is the manufacturer-recommended substitute for the obsolete AFBR-725TMZ. Both parts maintain identical electrical performance specifications across data rate, wavelength, voltage supply, and Ethernet application requirements. Both parts are ROHS3 compliant and carry MSL rating of 1 (Unlimited).

The primary distinction between these parts is product lifecycle status: the AFBR-725TMZ is obsolete, while the AFBR-735TMZ carries a Last Time Buy status, indicating continued but limited availability. The AFBR-735TMZ also carries an assigned ECCN classification (5A991B1) and HTSUS code (8517.62.0090), reflecting its active product status.

For new designs or replacement scenarios where the AFBR-725TMZ is no longer available, the AFBR-735TMZ provides electrical and mechanical compatibility while offering extended procurement windows relative to fully obsolete alternatives.

Frequently Asked Questions (FAQ)

Q: Can the AFBR-735TMZ directly replace the AFBR-725TMZ in existing systems?

A: The AFBR-735TMZ maintains identical electrical specifications (25.78125 Gbps data rate, 850nm wavelength, 3.1V–3.5V supply voltage) and uses the same LC duplex connector type. Both are pluggable transceiver modules compliant with ROHS3 standards. Compatibility depends on the host equipment's support for the SFP28 form factor used by the AFBR-735TMZ, as the original AFBR-725TMZ uses an SFP form factor.

Q: Why is the AFBR-725TMZ listed as obsolete?

A: The AFBR-725TMZ has reached end-of-life status and is no longer in active production. The AFBR-735TMZ represents the current-generation equivalent from Broadcom Limited, offering the same electrical performance with extended product lifecycle support.

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

A: Substitution eligibility is determined by matching data rate (25.78125 Gbps), wavelength (850nm), connector type (LC duplex), voltage supply range (3.1V–3.5V), and Ethernet application requirements. RoHS compliance status and moisture sensitivity ratings must also align.

Q: Are there inventory considerations when selecting between these parts?

A: The AFBR-725TMZ has 735 pieces in stock as new original inventory. The AFBR-735TMZ has 708 pieces in stock. However, the AFBR-725TMZ's obsolete status means inventory is non-replenishable, while the AFBR-735TMZ's Last Time Buy status indicates limited but potentially available procurement channels.

Q: What is the significance of the SFP versus SFP28 form factor difference?

A: Both SFP and SFP28 are pluggable transceiver form factors with identical electrical pin configurations for this application. The primary difference is physical form factor. Host equipment must explicitly support SFP28 modules to accommodate the AFBR-735TMZ. Compatibility verification with the target system is required before deployment.
