Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TS3USB221DRCRG4 is determined by strict equivalence across the following critical parameters:

• Base product number (TS3USB221)
• Multiplexer/demultiplexer circuit configuration (2:1)
• Switch circuit type (SPDT)
• Number of channels (2)
• On-state resistance maximum (6 Ohm)
• Supply voltage range (2.3V ~ 3.6V)
• Bandwidth specification (-3dB at 1.1 GHz)
• Bi-directional USB 2.0 capability
• Operating temperature range (-40°C ~ 85°C)
• Package type (10-VFDFN Exposed Pad / 10-VSON 3x3)
• Compliance certifications (ROHS3, REACH Unaffected)

Parts meeting all these parameters are classified as direct equivalents and may be substituted without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

The TS3USB221DRCR is the manufacturer-recommended substitute for the discontinued TS3USB221DRCRG4. Both parts share identical electrical specifications, functional characteristics, and compliance certifications. The primary distinction is product status: TS3USB221DRCR maintains active production status with substantial inventory availability (92,300 pcs), while TS3USB221DRCRG4 is discontinued.

From an engineering perspective, TS3USB221DRCR provides equivalent performance in all specified parameters and maintains ROHS3 compliance and REACH unaffected status. The substitute part is available in standard packaging formats (Cut Tape and Digi-Reel), supporting both prototype and production-volume procurement workflows.

Frequently Asked Questions (FAQ)

Q: Can TS3USB221DRCR be used as a direct replacement for TS3USB221DRCRG4?

A: Yes. Both parts are based on the same TS3USB221 base product number and share identical electrical specifications, switching characteristics, package type, and compliance certifications. No circuit modifications are required.

Q: Are there any differences in electrical performance between these parts?

A: No. Both parts specify identical on-state resistance (6 Ohm maximum), supply voltage range (2.3V ~ 3.6V), bandwidth (-3dB at 1.1 GHz), and operating temperature range (-40°C ~ 85°C).

Q: What is the difference between the packaging designations?

A: TS3USB221DRCRG4 packaging details were not specified in the original documentation. TS3USB221DRCR is available in Cut Tape (CT) and Digi-Reel® packaging formats, which are standard for production and automated assembly applications.

Q: Are both parts RoHS compliant?

A: Yes. Both TS3USB221DRCRG4 and TS3USB221DRCR are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Why is TS3USB221DRCRG4 discontinued?

A: Product discontinuation decisions are made by manufacturers based on market demand and product lifecycle management. TS3USB221DRCR remains in active production as the current equivalent offering.
