PI3V312QE Equivalent & Substitute Parts

Part Overview

The PI3V312QE is a 4-channel video multiplexer/demultiplexer IC manufactured by Diodes Incorporated, housed in a 16-QSOP surface mount package. This active component functions as a 2:1 switch circuit with SPDT (Single Pole Double Throw) configuration, designed for high-speed signal routing applications. The part is currently in active production status with 3,495 units in stock. Equivalent and substitute parts are identified when they maintain functional compatibility across critical electrical and mechanical parameters while meeting the same environmental and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PI3V312QE is determined by strict adherence to the following parameters:

• Switch circuit configuration must be SPDT
• Multiplexer/demultiplexer circuit must be 2:1
• Number of channels must be 4
• Package must be 16-SSOP (0.154", 3.90mm Width)
• Mounting type must be Surface Mount
• Operating temperature range must encompass -40°C to 85°C
• RoHS3 compliance and MSL 1 rating required

The identified substitute parts meet these core requirements while operating within compatible voltage supply ranges and maintaining functional performance across signal routing applications.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active production status and full RoHS3 compliance with MSL 1 rating, meeting the same environmental and regulatory requirements as the PI3V312QE.

ADG774ABRQZ and ADG774ABRQZ-REEL7 (Analog Devices): These parts are functionally equivalent with improved on-state resistance (4.6 Ohm vs. 8 Ohm) and support a wider supply voltage range (3V to 5V). The primary difference is packaging format: ADG774ABRQZ is supplied in Tube packaging, while ADG774ABRQZ-REEL7 is supplied in Cut Tape (CT) & Digi-Reel format. Both maintain identical electrical specifications and are suitable for direct substitution in applications where lower on-state resistance is beneficial.

QS4A205QG (Renesas Electronics): This substitute offers higher on-state resistance (17 Ohm) and operates at 5V supply voltage only. It provides superior -3dB bandwidth (830 MHz vs. 500 MHz) and lower charge injection (1.5pC vs. unspecified). This part is appropriate for applications requiring higher bandwidth performance where the increased on-state resistance is acceptable.

Frequently Asked Questions (FAQ)

Q: Can ADG774ABRQZ replace PI3V312QE in existing designs? A: Yes. Both parts share identical switch circuit configuration (SPDT), multiplexer/demultiplexer circuit (2:1), channel count (4), package (16-SSOP), and operating temperature range (-40°C to 85°C). The ADG774ABRQZ operates across a wider supply voltage range (3V to 5V) and features lower on-state resistance (4.6 Ohm), making it functionally compatible for direct substitution.

Q: What is the difference between ADG774ABRQZ and ADG774ABRQZ-REEL7? A: Both parts are electrically identical. The difference is packaging and delivery format. ADG774ABRQZ is supplied in Tube packaging, while ADG774ABRQZ-REEL7 is supplied in Cut Tape (CT) & Digi-Reel format. Selection depends on assembly process requirements and inventory management preferences.

Q: Is QS4A205QG suitable as a substitute for PI3V312QE? A: QS4A205QG meets the core substitution criteria: SPDT switch circuit, 2:1 multiplexer/demultiplexer configuration, 4 channels, 16-SSOP package, and -40°C to 85°C operating range. However, it requires 5V supply voltage (vs. 3.3V for PI3V312QE) and has higher on-state resistance (17 Ohm vs. 8 Ohm). Substitution is valid only if the application circuit supports 5V operation and can tolerate increased on-state resistance.

Q: Are all substitute parts RoHS3 compliant? A: Yes. PI3V312QE, ADG774ABRQZ, ADG774ABRQZ-REEL7, and QS4A205QG are all ROHS3 compliant with MSL 1 (Unlimited) rating, meeting identical environmental and regulatory standards.

Q: What are the key electrical differences between these parts? A: On-state resistance varies: PI3V312QE (8 Ohm), ADG774ABRQZ series (4.6 Ohm), and QS4A205QG (17 Ohm). Supply voltage requirements differ: PI3V312QE (3.3V), ADG774ABRQZ series (3V to 5V), and QS4A205QG (5V only). Bandwidth performance: PI3V312QE (500 MHz), ADG774ABRQZ series (400 MHz), and QS4A205QG (830 MHz). These differences must be evaluated against specific application requirements.
