Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HFBR-1522Z is determined by the following critical parameters: Connector Type (Versatile Link), RoHS compliance status, and MSL rating. The substitute parts AFBR-1521CZ and AFBR-1629Z share the Versatile Link connector interface, enabling mechanical and electrical compatibility within systems designed for this connector standard.

Wavelength variation between the main part (660nm) and substitutes (650nm) represents a spectral shift within the red light spectrum. Forward voltage and current specifications differ across the three parts, reflecting distinct design characteristics. The AFBR-1521CZ operates at lower maximum current (30 mA) with higher forward voltage (2.3V Max), while the AFBR-1629Z integrates a driver circuit and operates at supply voltages of 3.135V–3.465V or 4.75V–5.25V with 21 mA supply current.

All three parts maintain ROHS3 compliance and MSL 3 rating, supporting deployment in equivalent environmental and regulatory contexts.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and ROHS3 compliance, supporting continued use in new designs and existing production environments. The HFBR-1522Z and substitute parts share identical MSL 3 ratings and REACH Unaffected status, ensuring equivalent handling and storage requirements.

Selection between AFBR-1521CZ and AFBR-1629Z depends on circuit architecture requirements. The AFBR-1521CZ functions as a discrete transmitter element with specified forward voltage and current parameters. The AFBR-1629Z integrates transmitter and driver functionality, operating from dual supply voltage ranges (3.135V–3.465V or 4.75V–5.25V) with integrated 50MBd data rate capability.

Wavelength differences (660nm versus 650nm) must be evaluated against system receiver specifications and optical coupling requirements.

Frequently Asked Questions (FAQ)

Q: Can AFBR-1521CZ directly replace HFBR-1522Z in existing designs?

A: Mechanical compatibility is supported through the shared Versatile Link connector interface. Electrical compatibility requires verification of forward voltage (2.3V Max for AFBR-1521CZ versus 2.02V for HFBR-1522Z) and maximum forward current (30 mA for AFBR-1521CZ versus 80 mA for HFBR-1522Z) against circuit design specifications. Wavelength difference (650nm versus 660nm) must be evaluated against receiver sensitivity and optical system design.

Q: What is the primary functional difference between AFBR-1521CZ and AFBR-1629Z?

A: The AFBR-1521CZ is a discrete fiber optic transmitter element. The AFBR-1629Z integrates transmitter and driver circuitry, supporting 50MBd data rate operation and dual supply voltage ranges. Circuit integration requirements determine which part is appropriate for a given application.

Q: Are packaging differences significant for substitution?

A: Packaging format (Tube, Tray, Bulk) affects handling, storage, and procurement logistics but does not impact electrical or mechanical compatibility. Selection should align with production volume and inventory management requirements.

Q: Do all three parts share equivalent environmental compliance?

A: All three parts maintain ROHS3 compliance, MSL 3 rating (168 Hours), and REACH Unaffected status, supporting equivalent deployment in regulated environments.
