Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the AFBR-5905EZ is determined by alignment of the following critical parameters:

• Voltage Supply: 3.3V requirement
• Connector Type: MTRJ interface
• Mounting Type: Through Hole configuration
• Wavelength Range: 1300nm–1308nm band
• Applications: General Purpose optical transceiver function

The AFBR-5903AZ qualifies as a manufacturer-recommended substitute based on matching voltage supply (3.3V), connector type (MTRJ), mounting type (Through Hole), wavelength proximity (1300nm), and application category (General Purpose). The substitute maintains the same ECCN and HTSUS classifications, confirming regulatory alignment.

Parameter Comparison

Engineering Selection Recommendations

The AFBR-5903AZ is the manufacturer-recommended substitute for the obsolete AFBR-5905EZ. Both components share identical voltage supply (3.3V), connector type (MTRJ), mounting configuration (Through Hole), and regulatory classifications (ECCN 5A991B5A, HTSUS 8517.62.0090).

The AFBR-5903AZ offers improved product lifecycle status (Active versus Obsolete) and superior moisture sensitivity characteristics (MSL 1 versus MSL 3), providing enhanced reliability for new designs and system replacements. The wavelength difference (1300nm versus 1308nm) and specified data rate (100Mbps) on the substitute reflect its design parameters within the same optical transceiver category.

Frequently Asked Questions (FAQ)

Q: Can the AFBR-5903AZ directly replace the AFBR-5905EZ in existing systems?

A: The AFBR-5903AZ matches the critical electrical and mechanical parameters of the AFBR-5905EZ: 3.3V supply voltage, MTRJ connector, and Through Hole mounting. Both operate within the 1300nm wavelength band for general-purpose optical applications. Compatibility depends on system-level wavelength and data rate specifications.

Q: What is the significance of the wavelength difference between 1308nm and 1300nm?

A: Both wavelengths fall within the 1300nm optical window used for general-purpose transceiver applications. The 8nm difference reflects the specific design parameters of each component. System compatibility must be verified against the optical network specifications.

Q: Why does the AFBR-5903AZ have a lower MSL rating?

A: The AFBR-5903AZ carries MSL 1 (Unlimited moisture exposure tolerance) compared to the AFBR-5905EZ MSL 3 (168-hour limit). This indicates improved moisture resistance in the substitute component, beneficial for storage and handling in standard industrial environments.

Q: Are there regulatory or compliance differences between these parts?

A: Both components share identical ECCN (5A991B5A) and HTSUS (8517.62.0090) classifications. The AFBR-5903AZ is REACH Affected while the AFBR-5905EZ is REACH Unaffected; however, both maintain compliance within their respective regulatory frameworks.
