NXB0102UNZ Equivalent & Substitute Parts

Part Overview

The NXB0102UNZ is a voltage level translator IC manufactured by Nexperia USA Inc., designed for bidirectional signal translation between different voltage domains. This device operates as a single circuit with two channels, supporting data rates up to 100Mbps across voltage supplies ranging from 1.2V to 3.6V on the VCCA rail and 1.65V to 5.5V on the VCCB rail. The part is packaged in an 8-WLCSP (0.75x1.55mm) surface mount configuration with tri-state, non-inverted output characteristics.

The NXB0102UNZ currently holds an Obsolete product status. Locating equivalent substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production requirements for applications utilizing this voltage level translation function.

Substitute Part Grouping Explanation

Substitution of the NXB0102UNZ is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications for voltage translation capability, bidirectional channel configuration, data rate performance, and physical package dimensions to ensure direct compatibility within existing circuit designs.

The primary substitution criterion is the preservation of the following parameters:

• Translator Type: Voltage Level
• Channel Type: Bidirectional
• Number of Circuits: 1
• Channels per Circuit: 2
• Voltage - VCCA: 1.2V ~ 3.6V
• Voltage - VCCB: 1.65V ~ 5.5V
• Output Type: Tri-State, Non-Inverted
• Data Rate: 100Mbps
• Operating Temperature: -40°C ~ 125°C
• Package / Case: 8-UFBGA, WLCSP
• Supplier Device Package: 8-WLCSP (0.75x1.55)

Packaging format differences (Cut Tape versus Tape & Reel) do not affect electrical or mechanical compatibility and represent only supply chain and handling variations.

Parameter Comparison

Engineering Selection Recommendations

The NXB0102UNAZ serves as the direct parametric equivalent and substitute for the obsolete NXB0102UNZ. Both parts are manufactured by Nexperia USA Inc. and maintain identical electrical specifications, thermal operating range, and physical package dimensions. The NXB0102UNAZ holds Active product status, ensuring ongoing availability and supply chain support.

Selection of the NXB0102UNAZ is appropriate for new designs and production continuity applications. Both parts satisfy ROHS3 compliance and REACH unaffected regulatory requirements. The only distinction between these parts is the packaging format: the NXB0102UNZ is supplied in Cut Tape format, while the NXB0102UNAZ is supplied in Tape & Reel format. This difference reflects only the physical delivery and handling method and does not affect component performance or circuit functionality.

Frequently Asked Questions (FAQ)

Q: Can the NXB0102UNAZ directly replace the NXB0102UNZ in existing designs?

A: Yes. The NXB0102UNAZ is electrically and mechanically identical to the NXB0102UNZ. All voltage specifications, channel configurations, data rate performance, and package dimensions are equivalent. Direct substitution is supported without circuit modification.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) and Tape & Reel (TR) represent different supply formats for the same component. Cut Tape is supplied in shorter lengths for smaller quantity orders, while Tape & Reel is supplied on continuous reels for higher volume production. The physical component and its electrical characteristics remain identical.

Q: Why is the NXB0102UNZ marked as Obsolete?

A: Obsolete status indicates that the manufacturer has discontinued production of this specific part number. The NXB0102UNAZ, which maintains identical specifications, remains in Active production status and is the recommended source for continued supply.

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

A: No. Both the NXB0102UNZ and NXB0102UNAZ maintain identical RoHS3 compliance, REACH unaffected status, and Moisture Sensitivity Level (MSL) ratings. Regulatory and environmental compliance requirements are equivalent.

Q: What are the critical parameters for substitution compatibility?

A: Substitution compatibility is determined by matching the translator type (Voltage Level), channel configuration (Bidirectional, 1 circuit, 2 channels), voltage supply ranges (VCCA: 1.2V–3.6V; VCCB: 1.65V–5.5V), output type (Tri-State, Non-Inverted), data rate (100Mbps), operating temperature range (-40°C to 125°C), and physical package (8-WLCSP, 0.75x1.55mm). All these parameters are identical between the main part and substitute.

Q: Can the NXB0102UNAZ be used in applications requiring the Cut Tape format?

A: The NXB0102UNAZ is supplied in Tape & Reel format. If Cut Tape format is specifically required for assembly or handling processes, the Tape & Reel supply can typically be converted to cut tape format through standard component preparation procedures. The component itself is identical regardless of supply format.
