Key Parameters

Substitute Part Grouping Explanation

Substitution for the USB3311-GJ-TR is determined by strict alignment of the following electrical and mechanical parameters:

• Protocol Compatibility: USB 2.0 transceiver functionality
• Package Compatibility: 25-VFBGA (3x3) form factor for direct PCB footprint match
• Voltage Supply Range: 1.6V ~ 3.6V operating range
• Operating Temperature Range: -40°C ~ 85°C
• Mounting Type: Surface Mount
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected

The USB3311C-GJ-TR qualifies as a direct substitute based on identical alignment across all these parameters. Both parts share the same base product number (USB3311), manufacturer (Microchip Technology), and series designation (flexPWR™).

Parameter Comparison

Engineering Selection Recommendations

The USB3311C-GJ-TR is the qualified substitute for the USB3311-GJ-TR. Both components maintain identical electrical and mechanical specifications, ensuring functional equivalence in circuit applications. The primary distinction is product status: the original part is obsolete while the substitute remains in active production.

The USB3311C-GJ-TR offers an additional advantage in moisture sensitivity classification (MSL 1 versus MSL 3), providing improved handling flexibility during storage and assembly operations. Both parts maintain full ROHS3 compliance and REACH compliance status, satisfying regulatory requirements for current manufacturing standards.

Frequently Asked Questions (FAQ)

Q: Can the USB3311C-GJ-TR be used as a direct replacement for the USB3311-GJ-TR?

A: Yes. Both parts are identical in electrical performance, package form factor, and operating specifications. The USB3311C-GJ-TR is the active production equivalent.

Q: Are there any pin or footprint differences between these parts?

A: No. Both components use the 25-VFBGA (3x3) package with identical pinout and PCB footprint requirements.

Q: What is the significance of the different MSL ratings?

A: MSL 1 (USB3311C-GJ-TR) allows unlimited shelf life under controlled conditions, while MSL 3 (USB3311-GJ-TR) requires reflow processing within 168 hours of moisture exposure. The substitute part offers superior handling characteristics.

Q: Do both parts meet current regulatory compliance standards?

A: Yes. Both the USB3311-GJ-TR and USB3311C-GJ-TR are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Why is the original part marked as obsolete?

A: Microchip Technology has transitioned the USB3311-GJ-TR to end-of-life status. The USB3311C-GJ-TR represents the active production line for this transceiver family.
