TXB0102DCUTG4 Equivalent & Substitute Parts

Part Overview

The TXB0102DCUTG4 is a voltage level translator IC from Texas Instruments designed for bidirectional signal conversion between different voltage domains. This device translates signals between a 1.2 V to 3.6 V domain (VCCA) and a 1.65 V to 5.5 V domain (VCCB) with a single circuit containing two channels operating at 100 Mbps. The part is currently discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

All substitute parts listed are parametric equivalents of the TXB0102DCUTG4, sharing identical electrical and mechanical specifications. Substitution is determined by the following criteria:

Same base product number (TXB0102)
Identical voltage translation ranges (VCCA: 1.2 V ~ 3.6 V; VCCB: 1.65 V ~ 5.5 V)
Same channel configuration (1 circuit, 2 bidirectional channels)
Matching data rate (100 Mbps)
Identical package type (8-VFSOP)
Same output characteristics (Tri-State, Non-Inverted)
Equivalent operating temperature range (-40°C ~ 85°C)
Auto-Direction Sensing feature present

The primary differences among substitute parts are packaging format (Cut Tape vs. Tape & Reel) and product status (Active vs. Discontinued).

Engineering Selection Recommendations

For applications requiring the TXB0102DCUTG4, the following substitute parts provide full electrical and mechanical compatibility:

Primary Recommendation: TXB0102DCUT This part is currently active in production and available in Cut Tape packaging with 31,086 units in stock. It maintains all electrical specifications and compliance certifications identical to the original part.

Secondary Recommendation: TXB0102DCUR This part is also active in production with the highest inventory availability (87,664 units). It differs only in packaging format (Cut Tape & Digi-Reel®) and is suitable for high-volume procurement.

Alternative: TXB0102DCURG4 This part maintains the same electrical specifications but is currently discontinued at DiGi Electronics. It is available in Tape & Reel packaging with 19,625 units in stock and may be sourced through alternative distributors.

All substitute parts carry ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for the original application.

Frequently Asked Questions (FAQ)

Q: Can TXB0102DCUR be used as a direct replacement for TXB0102DCUTG4? A: Yes. Both parts share identical electrical specifications, voltage ranges, channel configuration, data rate, and operating temperature range. The only difference is packaging format. TXB0102DCUR uses Cut Tape & Digi-Reel® packaging versus the tube packaging of the original part.

Q: What is the difference between Cut Tape and Tape & Reel packaging? A: Cut Tape (CT) & Digi-Reel® packaging is suitable for lower-volume applications and manual assembly. Tape & Reel (TR) packaging is designed for automated pick-and-place equipment in high-volume manufacturing. Both formats contain the same die and electrical performance.

Q: Are all substitute parts RoHS compliant? A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory standards.

Q: Why is the original TXB0102DCUTG4 discontinued? A: Product discontinuation is a manufacturer decision. Active substitute parts with identical specifications are available to support ongoing designs.

Q: Can I mix different packaging formats in the same production run? A: Electrical performance is identical across all packaging formats. However, assembly process compatibility should be verified with your manufacturing partner, as different packaging formats require different handling equipment.

Q: What is the Moisture Sensitivity Level (MSL) rating? A: All parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
