Key Parameters

Substitute Part Grouping Explanation

Substitute components for the PI3VT3306L are qualified based on the following electrical and mechanical parameters:

• Bus switch type with 1 x 1:1 circuit configuration
• Two independent circuits
• Single supply voltage operation
• Voltage supply range compatibility: 2.3V ~ 3.6V
• Operating temperature range: -40°C ~ 85°C
• Surface mount packaging in 8-TSSOP form factor
• Package dimensions: 0.173" width, 4.40mm width specification

Both identified substitutes meet these core requirements and are available in active product status with current manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

The PI3VT3306L is obsolete and no longer in active production. Two qualified substitutes are available:

PI3VT3306LE (Diodes Incorporated) is the direct manufacturer alternative, maintaining identical electrical specifications and packaging. This part is ROHS3 compliant and actively manufactured, with 9931 units in stock. Selection of this part provides continuity with the original design while ensuring regulatory compliance and supply availability.

SN74CB3Q3305PWR (Texas Instruments) is a cross-manufacturer substitute from the 74CB series. This part meets all electrical and mechanical requirements with ROHS3 compliance and active production status. Inventory availability is 49100 units. The voltage supply specification is consolidated to 2.3V ~ 3.6V, which encompasses the operating ranges of the original part.

Both substitutes are suitable for direct replacement in applications requiring bus switch functionality with the specified electrical and thermal parameters.

Frequently Asked Questions (FAQ)

Q: Can PI3VT3306LE be used as a direct replacement for PI3VT3306L?

A: Yes. Both parts share identical electrical specifications, circuit configuration, voltage supply ranges, operating temperature range, and 8-TSSOP packaging. The primary difference is product status: PI3VT3306LE is active and ROHS3 compliant, while PI3VT3306L is obsolete and RoHS non-compliant.

Q: What are the key differences between PI3VT3306LE and SN74CB3Q3305PWR?

A: Both parts meet the core substitution criteria: 1 x 1:1 bus switch configuration, 2 independent circuits, single supply operation, -40°C to 85°C operating range, and 8-TSSOP packaging. The voltage supply specification differs slightly: PI3VT3306LE specifies 2.3V ~ 2.7V and 3V ~ 3.6V ranges, while SN74CB3Q3305PWR specifies a consolidated 2.3V ~ 3.6V range. Both ranges are functionally compatible with the original PI3VT3306L design.

Q: Are there any packaging or pinout differences between these substitutes?

A: No. All three parts use identical 8-TSSOP packaging with 0.173" width and 4.40mm width specification. Pinout compatibility is maintained across all substitutes.

Q: What is the significance of RoHS compliance for these parts?

A: PI3VT3306L is RoHS non-compliant, while both PI3VT3306LE and SN74CB3Q3305PWR are ROHS3 compliant. For applications subject to RoHS regulations or customer requirements, the compliant substitutes are necessary.

Q: Which substitute should be selected for new designs?

A: Selection depends on supply chain and design requirements. PI3VT3306LE provides manufacturer continuity with Diodes Incorporated. SN74CB3Q3305PWR provides cross-manufacturer qualification with higher inventory availability. Both are active products with ROHS3 compliance suitable for new production.
