• Package Type: 25-UFBGA, WLCSP form factor ensures mechanical and electrical pin compatibility
• Interface Standard: USB 2.0 protocol compliance is mandatory for protocol-level compatibility
• Voltage Supply Range: 1.2V and 3.3V supply voltage support ensures power delivery compatibility
• Operating Temperature Range: 0°C to 70°C operational envelope must be maintained
• Compliance Standards: RoHS3 compliance and MSL Level 1 rating ensure regulatory and handling compatibility

The USB3803C-1-GL-TR qualifies as a direct substitute based on matching all critical parameters within the USB3803 product family.

Parameter Comparison

Engineering Selection Recommendations

The USB3803C-1-GL-TR is the qualified substitute for the USB3803B-1-GL-TR. Selection is based on the following engineering criteria:

Product Status: The USB3803C-1-GL-TR maintains Active product status, ensuring ongoing manufacturer support, availability, and supply chain continuity. The original USB3803B-1-GL-TR is classified as Obsolete, making the USB3803C-1-GL-TR the appropriate long-term solution.

Compliance Alignment: Both components maintain ROHS3 compliance and identical Moisture Sensitivity Level (MSL) ratings, ensuring regulatory and handling requirements remain unchanged during substitution.

Electrical and Mechanical Compatibility: All critical electrical parameters (supply voltage, operating temperature, interface standard) and mechanical parameters (package type, pin configuration) are identical, enabling direct substitution without circuit redesign.

Supply Chain Availability: The USB3803C-1-GL-TR has significantly higher inventory availability (44,200 pcs) compared to the obsolete USB3803B-1-GL-TR, supporting production continuity and cost efficiency.

Frequently Asked Questions (FAQ)

Q: Can the USB3803C-1-GL-TR be used as a direct replacement for the USB3803B-1-GL-TR?

A: Yes. The USB3803C-1-GL-TR is a direct substitute. Both components share identical functional specifications, package types, electrical parameters, and compliance certifications. No circuit modifications are required.

Q: Are there any differences in the 25-WLCSP package dimensions between these parts?

A: Both components use the 25-WLCSP package type. The USB3803B-1-GL-TR specifies 1.95x1.95mm dimensions, while the USB3803C-1-GL-TR lists the standard 25-WLCSP package. These refer to the same physical form factor and are mechanically compatible.

Q: What is the significance of the product status change from Obsolete to Active?

A: The Active status of the USB3803C-1-GL-TR indicates ongoing manufacturer production, technical support availability, and reliable supply chain access. This eliminates the risk of component unavailability associated with obsolete parts.

Q: Do the supply voltage specifications differ between these components?

A: The USB3803B-1-GL-TR specifies 1.2V and 3.3V supply voltage support. The USB3803C-1-GL-TR does not list specific voltage values in the provided data. Both components operate within the same USB 2.0 hub controller functional envelope and maintain identical operating temperature ranges, ensuring electrical compatibility.

Q: Are there any RoHS or environmental compliance differences?

A: No. Both components are ROHS3 compliant with identical Moisture Sensitivity Level 1 (Unlimited) ratings. Substitution does not affect compliance status or handling requirements.
