Substitute Part Grouping Explanation
Substitution of the MPC509AUG4 is determined by strict alignment of core functional and electrical parameters. All substitute parts must maintain the SP4T switch configuration with 4:1 multiplexer/demultiplexer architecture and 2-circuit topology. The primary substitution criterion is compatibility within the dual supply voltage range; however, substitute parts may operate across different voltage windows provided they encompass the application's required operating point.
On-state resistance varies among substitutes (ranging from 270Ohm to 1.5kOhm), which affects signal attenuation and power dissipation characteristics. Switch timing parameters (Ton and Toff) differ across alternatives, impacting maximum switching frequency suitability. Channel capacitance and leakage current specifications influence high-frequency performance and signal integrity in precision applications.
Package compatibility is mandatory: all substitutes are available in 16-SOIC surface mount configuration. Operating temperature range (-40°C to 85°C) is consistent across all listed alternatives, ensuring thermal compatibility. RoHS3 compliance and MSL ratings are provided for all parts, supporting environmental and manufacturing process requirements.

Engineering Selection Recommendations
MPC509AU is the direct Texas Instruments equivalent with identical electrical specifications and packaging. This part maintains 1.5kOhm on-state resistance, ±5V to ±22V dual supply range, and 200ns/250ns switching times. MPC509AU is active in production with 6101 units in stock, providing the most straightforward replacement path for existing MPC509AUG4 designs without circuit modification.
ADG509AKRZ-REEL and ADG509AKRZ-REEL7 (Analog Devices) offer reduced on-state resistance of 450Ohm with faster switching characteristics (300ns). These parts operate within ±10.8V to ±16.5V dual supply range, which is narrower than the original specification. Selection is appropriate for applications where lower on-state resistance and improved switching speed are beneficial and supply voltage constraints are acceptable. Available in both Tape & Reel and Cut Tape packaging.
ADG509FBRNZ and ADG509FBRWZ provide the lowest on-state resistance at 270Ohm (Typ) with improved switching performance (230ns Ton, 130ns Toff). These parts require fixed ±15V dual supply operation and are suitable for precision signal routing applications where lower impedance and faster switching are critical. Moisture sensitivity is MSL 1 (Unlimited), providing superior handling characteristics.
DG509ACWE+, DG509ADY+, and DG509AEWE+ (Analog Devices/Maxim) feature 450Ohm on-state resistance with extended dual supply range of ±4.5V to ±18V. These parts exhibit slower switching times (1.5µs Ton, 1µs Toff) compared to the original specification. DG509ACWE+ operates at 0°C to 70°C temperature range, while DG509ADY+ and DG509AEWE+ support the full -40°C to 85°C range. Selection depends on application switching frequency requirements and operating temperature constraints.
MAX355CWE+ (Analog Devices/Maxim) combines moderate on-state resistance of 350Ohm with fast switching (250ns Ton, 200ns Toff) and the lowest channel capacitance (1.6pF CS(off), 5pF CD(off)). This part supports both single supply (4.5V to 36V) and dual supply (±4.5V to ±18V) operation, offering maximum flexibility. Operating temperature is 0°C to 70°C. Crosstalk specification of -92dB @ 100kHz is provided, supporting high-frequency applications.
All substitute parts maintain ROHS3 compliance and 16-SOIC surface mount packaging. Selection should prioritize supply voltage compatibility with the target application, switching speed requirements, and on-state resistance impact on signal integrity and power dissipation.
Frequently Asked Questions (FAQ)
Q: Can MPC509AU be used as a direct replacement for MPC509AUG4?
A: Yes. MPC509AU is the active production equivalent with identical electrical specifications: 1.5kOhm on-state resistance, ±5V to ±22V dual supply range, 200ns/250ns switching times, and 16-SOIC packaging. No circuit modifications are required.
Q: What is the primary difference between MPC509AU and the Analog Devices ADG509 series?
A: The ADG509 series offers lower on-state resistance (270Ohm to 450Ohm) and faster switching performance compared to MPC509AU (1.5kOhm, 200ns/250ns). However, ADG509 parts operate within narrower supply voltage ranges (±10.8V to ±16.5V or fixed ±15V) compared to MPC509AU's ±5V to ±22V range. Selection depends on application supply voltage constraints and impedance requirements.
Q: Are all substitute parts available in the same 16-SOIC package?
A: All substitute parts are available in 16-SOIC surface mount packaging. However, package body width varies: MPC509AU, DG509ACWE+, DG509AEWE+, and MAX355CWE+ use 0.295" (7.50mm) width, while ADG509AKRZ-REEL, ADG509AKRZ-REEL7, ADG509FBRNZ, ADG509FBRNZ-REEL7, and DG509ADY+ use 0.154" (3.90mm) width. PCB layout compatibility should be verified before selection.
Q: Which substitute part offers the fastest switching performance?
A: ADG509FBRNZ and ADG509FBRWZ provide the fastest switching times: 230ns Ton and 130ns Toff. These parts require fixed ±15V dual supply operation and are optimized for high-speed signal routing applications.
Q: What is the operating temperature range for each substitute?
A: MPC509AU, ADG509AKRZ-REEL, ADG509AKRZ-REEL7, ADG509FBRNZ, ADG509FBRNZ-REEL7, DG509ADY+, and DG509AEWE+ support -40°C to 85°C. DG509ACWE+ and MAX355CWE+ operate within 0°C to 70°C range. Application thermal requirements should determine selection.
Q: Can MAX355CWE+ operate from single supply voltage?
A: Yes. MAX355CWE+ supports both single supply (4.5V to 36V) and dual supply (±4.5V to ±18V) operation, providing maximum flexibility for diverse power supply architectures. Other substitutes require dual supply operation.
Q: What packaging options are available for the ADG509 series?
A: ADG509AKRZ-REEL is supplied in Tape & Reel (TR) format. ADG509AKRZ-REEL7 is supplied in Cut Tape (CT) & Digi-Reel format. ADG509FBRNZ and ADG509FBRWZ are supplied in Tube packaging. Selection depends on production volume and assembly process requirements.
Q: How does on-state resistance affect circuit performance?
A: Lower on-state resistance reduces signal attenuation and power dissipation in the switch element. MPC509AU and MPC509AUG4 feature 1.5kOhm resistance, while ADG509FBRNZ offers 270Ohm (Typ). Applications requiring minimal signal loss or operating at high current levels benefit from lower on-state resistance. Trade-offs include increased leakage current and different supply voltage requirements.
Q: Are all substitute parts RoHS3 compliant?
A: Yes. All listed substitute parts are ROHS3 compliant and support environmental and regulatory requirements for lead-free manufacturing and hazardous substance restrictions.
