Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLV313IDCKT is determined by strict alignment of the following critical parameters:

Electrical Compatibility Criteria:

• Amplifier Type: General Purpose
• Number of Circuits: 1
• Output Type: Rail-to-Rail
• Supply Voltage Range: 1.8V to 5.5V minimum and maximum
• Operating Temperature Range: -40°C to 125°C
• Input Bias Current: 1 pA
• Package compatibility: 5-TSSOP, SC-70-5, SOT-353

Compliance Requirements:

• RoHS3 Compliant status
• REACH Unaffected status
• Active product status

The NCS20081SQ3T2G from onsemi meets all electrical and mechanical substitution criteria. While certain performance parameters differ (slew rate, gain bandwidth product, input offset voltage, and supply current), these variations remain within acceptable tolerances for general purpose amplifier applications and do not preclude functional equivalence in the specified supply and temperature operating ranges.

Parameter Comparison

Engineering Selection Recommendations

Both the TLV313IDCKT and NCS20081SQ3T2G are active production devices with full RoHS3 compliance and REACH unaffected status, making them suitable for applications requiring regulatory compliance in industrial and commercial environments.

The TLV313IDCKT is the primary reference device with established design history and 842 units in current inventory. The NCS20081SQ3T2G serves as a qualified substitute with significantly higher inventory availability (20,400 units) and improved performance characteristics in supply current efficiency and input offset voltage specification.

Selection between these devices should be based on:

1. Inventory Availability: NCS20081SQ3T2G offers substantially higher stock levels for high-volume production requirements.

2. Supply Current Efficiency: NCS20081SQ3T2G operates at 48µA versus 65µA, providing 26% lower quiescent current consumption.

3. Input Offset Voltage: NCS20081SQ3T2G specifies 500µV versus 750µV, offering improved DC accuracy.

4. Gain Bandwidth Product: NCS20081SQ3T2G provides 1.2MHz versus 1MHz, enabling slightly faster signal processing.

Both devices maintain identical supply voltage ranges (1.8V to 5.5V), operating temperature specifications (-40°C to 125°C), and package compatibility (SC-70-5/SOT-353), ensuring direct functional substitution in existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the NCS20081SQ3T2G directly replace the TLV313IDCKT in existing PCB designs?
