Key Parameters

Substitute Part Grouping Explanation

Substitution for the TUSB2046BVFG4 is determined by strict equivalence across the following critical parameters:

• Package Type: 32-LQFP (7x7) form factor
• Interface Protocol: USB 2.0
• Function: Hub Controller
• Voltage Supply: 3V ~ 3.6V
• Supply Current: 40mA
• Operating Temperature Range: 0°C ~ 70°C
• Compliance: ROHS3 Compliant, REACH Unaffected
• Moisture Sensitivity: MSL 3 (168 Hours)

Two substitute parts meet these criteria: TUSB2046BVF (manufacturer-recommended substitute with active product status) and TUSB2036VF (parametric equivalent with active product status). A third part, TUSB2036VFG4, is a parametric equivalent but shares discontinued status with the original part.

Parameter Comparison

Engineering Selection Recommendations

For new designs and production continuity, TUSB2046BVF is the primary substitute. This part is manufacturer-recommended, maintains active product status, and is available in standard tray packaging. All electrical and mechanical parameters are identical to the original TUSB2046BVFG4.

TUSB2036VF serves as a secondary parametric equivalent with active product status and tray packaging. This part maintains full electrical and thermal compatibility while offering superior long-term availability.

TUSB2036VFG4 is not recommended for new applications due to discontinued status, despite meeting all parametric requirements.

Frequently Asked Questions (FAQ)

Q: Can TUSB2046BVF directly replace TUSB2046BVFG4 in existing designs?

A: Yes. Both parts share identical electrical specifications (3V–3.6V supply, 40mA current, 0°C–70°C operating range), the same 32-LQFP (7x7) package, and equivalent compliance certifications. The primary difference is packaging format (tray vs. unspecified) and active product status.

Q: What is the difference between TUSB2046BVF and TUSB2036VF?

A: Both are parametric equivalents with identical electrical and thermal characteristics. The difference lies in the base product number (TUSB2046 vs. TUSB2036). Both are active products in tray packaging and meet all substitution criteria.

Q: Why is TUSB2036VFG4 not recommended despite meeting all parameters?

A: TUSB2036VFG4 is discontinued at DiGi Electronics, creating supply chain risk. TUSB2046BVF and TUSB2036VF are active products with confirmed availability.

Q: Are there any package compatibility concerns?

A: No. All substitute parts use the 32-LQFP (7x7) package, ensuring PCB footprint and pin compatibility.

Q: Do all parts meet the same compliance standards?

A: Yes. All parts are ROHS3 Compliant, REACH Unaffected, with MSL 3 (168 Hours) moisture sensitivity rating.
