AFBR-79EIDZ Equivalent & Substitute Parts

Part Overview

The AFBR-79EIDZ is a transceiver module designed for telecom and datacom systems operating at 40Gbe with 850nm wavelength. This Broadcom Limited component features a 3.3V supply voltage and MTP® (MPO) pluggable QSFP+ form factor. The product is currently classified as obsolete, making identification of compatible substitute parts essential for system maintenance, upgrades, and procurement planning. Substitute parts must maintain electrical and mechanical compatibility across data rate, wavelength, voltage supply, connector type, and mounting specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AFBR-79EIDZ are identified based on strict alignment with the following critical parameters:

• Data Rate: 40Gbe (mandatory match)
• Wavelength: 850nm (mandatory match)
• Connector Type: MTP® (MPO) (mandatory match)
• Mounting Type: Pluggable, QSFP+ (mandatory match)
• Voltage - Supply: 3.3V (mandatory match)

The AFBR-79EIDZ-C qualifies as a substitute part because it maintains equivalence across all critical electrical and mechanical parameters. Compliance certifications and product status are secondary considerations that inform selection context but do not disqualify substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

The AFBR-79EIDZ-C is electrically and mechanically equivalent to the AFBR-79EIDZ across all critical operating parameters. Both parts operate at 40Gbe data rate with 850nm wavelength, utilize MTP® (MPO) connectors, and employ QSFP+ pluggable form factors. Both are RoHS compliant, satisfying environmental regulatory requirements.

The primary distinction is product status: the original AFBR-79EIDZ is obsolete, while the AFBR-79EIDZ-C is active. For new system designs or long-term procurement strategies, the active status of the AFBR-79EIDZ-C provides supply chain continuity. For legacy system maintenance requiring exact original component replacement, the AFBR-79EIDZ remains available in current inventory (685 Pcs).

Frequently Asked Questions (FAQ)

Q: Can the AFBR-79EIDZ-C directly replace the AFBR-79EIDZ in existing systems?

A: Yes. Both parts share identical electrical specifications (40Gbe, 850nm, 3.3V) and mechanical form factors (MTP® MPO connector, QSFP+ pluggable). Direct substitution is supported without system modification.

Q: What is the significance of the product status difference?

A: The AFBR-79EIDZ is classified as obsolete, indicating Broadcom Limited has discontinued production. The AFBR-79EIDZ-C maintains active status, ensuring ongoing availability for future procurement. For immediate replacement needs, both parts are currently in stock.

Q: Are there compliance differences between these parts?

A: Both parts are RoHS compliant. The AFBR-79EIDZ carries ROHS3 certification, while the AFBR-79EIDZ-C carries general RoHS compliance. Both satisfy environmental regulatory requirements for telecom and datacom applications.

Q: What connector compatibility should be verified?

A: Both parts utilize MTP® (MPO) connectors in QSFP+ form factor. Verify that host equipment supports MTP® (MPO) connector interfaces. No adapter or conversion is required for substitution.

Q: Are there packaging differences?

A: The AFBR-79EIDZ is supplied without specified packaging designation. The AFBR-79EIDZ-C is supplied in retail package format. This distinction affects storage and handling but does not impact electrical or mechanical performance.
