NTSX2102TLH Equivalent & Substitute Parts

Part Overview

The NTSX2102TLH is a voltage level translator IC manufactured by NXP 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 50 Mbps with open drain output configuration. The part is currently in Active product status with 3,626 units available in inventory.

Substitute parts are identified when equivalent functional performance can be achieved within the allowed electrical and mechanical parameter ranges. Alternative models may be required due to inventory constraints, packaging preferences, or supply chain considerations while maintaining compatibility with the application requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the NTSX2102TLH is determined by the following critical parameters:

Core Functional Requirements:

Translator Type: Voltage Level
Channel Type: Bidirectional
Number of Circuits: 1
Channels per Circuit: 2
Output Type: Open Drain
Operating Temperature Range: -40°C ~ 85°C (TA)

Voltage Domain Compatibility: Substitute parts must support overlapping voltage ranges for both VCCA and VCCB. The NTSX2102TLH operates with VCCA and VCCB from 1.65 V to 5.5 V. Substitute devices must accommodate the voltage domains required by the application within their specified ranges.

Performance Characteristics: Data rate capability and mounting type are secondary selection criteria. The NTSX2102TLH supports 50 Mbps; substitute parts with lower data rates remain compatible if application bandwidth requirements do not exceed the substitute's specification.

Compliance and Packaging: All identified substitutes maintain ROHS3 compliance, REACH unaffected status, and MSL 1 rating. Package form factor differences are noted but do not preclude substitution when PCB layout accommodates the alternative package type.

Engineering Selection Recommendations

PI6ULS5V9306UEX (Diodes Incorporated): This substitute is suitable for applications where VCCA operates within 1 V to 3.3 V and VCCB operates within 1.8 V to 5.5 V. The device maintains Active product status with 15,100 units in inventory. The 8-SOIC package requires PCB layout modification compared to the XFDFN package of the original part. Auto-direction sensing feature is included. This option provides the highest inventory availability among substitutes.

PI6ULS5V9306ZEEX (Diodes Incorporated): This substitute operates with identical voltage ranges to the PI6ULS5V9306UEX (VCCA: 1 V ~ 3.3 V, VCCB: 1.8 V ~ 5.5 V) and is packaged in 8-WFDFN format, which more closely matches the footprint profile of the original XFDFN package. However, this part carries Last Time Buy status with 6,200 units available. Selection of this part should account for long-term supply considerations.

TXS0202YZPR (Texas Instruments): This substitute operates with VCCA and VCCB both ranging from 1.65 V to 3.6 V, providing the most restrictive voltage domain coverage among the three alternatives. Data rate is specified at 15 Mbps, which is lower than the original 50 Mbps specification. The 8-DSBGA package represents a significant departure from the original XFDFN footprint and requires BGA assembly capability. This option maintains Active product status with 4,400 units in inventory and includes auto-direction sensing.

Compliance Basis: All substitute parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 moisture sensitivity rating, ensuring regulatory and environmental compatibility with the original part.

Frequently Asked Questions (FAQ)

Q: Can PI6ULS5V9306UEX replace NTSX2102TLH in all applications?

A: PI6ULS5V9306UEX is compatible only when application voltage domains fall within its specified ranges: VCCA 1 V to 3.3 V and VCCB 1.8 V to 5.5 V. If the original design requires VCCA operation above 3.3 V or VCCB below 1.8 V, this substitute is not suitable. The 8-SOIC package also requires PCB layout changes.

Q: What is the primary difference between PI6ULS5V9306UEX and PI6ULS5V9306ZEEX?

A: Both devices share identical electrical specifications and voltage ranges. The primary difference is packaging: PI6ULS5V9306UEX uses 8-SOIC format while PI6ULS5V9306ZEEX uses 8-WFDFN format. Additionally, PI6ULS5V9306ZEEX carries Last Time Buy status, indicating limited future availability.

Q: Is TXS0202YZPR suitable for high-speed applications?

A: TXS0202YZPR supports 15 Mbps data rate, which is lower than the NTSX2102TLH specification of 50 Mbps. Selection of this part is appropriate only when application bandwidth requirements do not exceed 15 Mbps. The 8-DSBGA package also requires BGA-capable assembly processes.

Q: Do all substitute parts support the same voltage ranges as the original NTSX2102TLH?

A: No. The NTSX2102TLH supports VCCA and VCCB from 1.65 V to 5.5 V. Diodes substitutes limit VCCA to 1 V to 3.3 V, and TXS0202YZPR limits both supplies to 1.65 V to 3.6 V. Voltage domain compatibility must be verified against application requirements before substitution.

Q: Are there package compatibility considerations when substituting these parts?

A: Yes. The original NTSX2102TLH uses 8-XFDFN package. PI6ULS5V9306UEX uses 8-SOIC, PI6ULS5V9306ZEEX uses 8-WFDFN, and TXS0202YZPR uses 8-DSBGA. Each package requires different PCB footprints and assembly processes. PCB layout must be verified or redesigned to accommodate the substitute package.

Q: What does Last Time Buy status mean for PI6ULS5V9306ZEEX?

A: Last Time Buy status indicates that the manufacturer has announced end-of-life for this product. While 6,200 units are currently in inventory, future availability is limited. This part should be selected only when long-term supply is not a concern or when alternative substitutes do not meet application requirements.

Q: Do all substitute parts include auto-direction sensing?

A: No. The original NTSX2102TLH does not list auto-direction sensing as a feature. PI6ULS5V9306UEX and PI6ULS5V9306ZEEX include auto-direction sensing, while TXS0202YZPR also includes this feature. Auto-direction sensing is an additional capability that does not affect basic substitution compatibility.

Q: What compliance certifications apply to all parts in this comparison?

A: All parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 (Unlimited) moisture sensitivity level. These certifications ensure regulatory and environmental compatibility across all options.
