DG211BDY Equivalent & Substitute Parts

Part Overview

The DG211BDY is a 4-circuit SPST-NC analog switch IC manufactured by Vishay Siliconix, housed in a 16-SOIC surface mount package. This component operates across a wide supply voltage range (4.5V to 25V single supply, or ±4.5V to ±22V dual supply) with an 85Ohm on-state resistance and 300ns/200ns switching times. The DG211BDY is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production support. Direct replacements and parametric equivalents are available from both Vishay Siliconix and Analog Devices Inc., with varying electrical characteristics suited to different application requirements.

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance): DG211BDY-E3 is the primary choice for applications requiring identical electrical specifications to the obsolete DG211BDY. This part maintains all critical parameters including 85Ohm on-state resistance, 300ns/200ns switching times, and full supply voltage range compatibility. The part is in active production status with RoHS3 compliance, making it suitable for new designs and legacy system updates.

For Parametric Equivalence (Same Base Functionality): DG201BDY-E3 provides identical electrical performance to DG211BDY-E3 with active product status and RoHS3 compliance. This part is functionally interchangeable for applications where the base product number change is acceptable.

For Applications with Relaxed Supply Voltage Requirements: ADG211AKRZ, ADG211AKRZ-REEL, and ADG211AKRZ-REEL7 are suitable when designs operate at fixed 15V single supply or ±15V dual supply. These parts accept higher on-state resistance (115Ohm) and slower switching times (600ns/450ns) but maintain active production status and RoHS3 compliance. Tape & Reel packaging options (REEL and REEL7) are available for high-volume production.

For Applications with Dual Supply Only: DG211CSE+, DG211CSE+T, DG211DY+, and DG211DY+T are applicable when designs use dual supply operation (±4.5V ~ 18V) exclusively. These parts feature higher on-state resistance (175Ohm) and slower switching times (1µs/500ns). DG211DY+ and DG211DY+T support the full -40°C ~ 85°C operating temperature range, while DG211CSE+ and DG211CSE+T are limited to 0°C ~ 70°C. All maintain active status and RoHS3 compliance.

For Low-Resistance Applications: MAX4604CSE+ is selected when applications require minimal on-state resistance (4Ohm) and fast switching performance (120ns/130ns). This part supports wider single supply range (4.5V ~ 36V) and dual supply (±4.5V ~ 20V), with active status and RoHS3 compliance. Operating temperature is limited to 0°C ~ 70°C.

All substitute parts are RoHS3 compliant and in active production, eliminating obsolescence risk associated with the original DG211BDY.

Frequently Asked Questions (FAQ)

Q: Can DG211BDY-E3 be used as a direct replacement for DG211BDY? A: Yes. DG211BDY-E3 maintains identical electrical specifications including on-state resistance (85Ohm), switching times (300ns/200ns), supply voltage ranges (4.5V ~ 25V single, ±4.5V ~ 22V dual), and operating temperature (-40°C ~ 85°C). The primary difference is packaging format (Tube vs. Reel) and active product status with RoHS3 compliance.

Q: What is the difference between DG211BDY-E3 and DG201BDY-E3? A: Both parts are parametrically equivalent with identical electrical performance. The base product number differs (DG211 vs. DG201), but all critical parameters including on-state resistance, switching times, supply voltages, and operating temperature are identical. Both are in active production with RoHS3 compliance.

Q: Can ADG211AKRZ replace DG211BDY in all applications? A: ADG211AKRZ is not a direct replacement. While it maintains the same 4-circuit SPST-NC configuration and 16-SOIC package, it has higher on-state resistance (115Ohm vs. 85Ohm), reduced supply voltage range (15V single, ±15V dual vs. 4.5V ~ 25V single, ±4.5V ~ 22V dual), and slower switching times (600ns/450ns vs. 300ns/200ns). Use only when your application operates at fixed 15V supply and can tolerate these performance differences.

Q: What is the difference between ADG211AKRZ-REEL and ADG211AKRZ-REEL7? A: Both parts are electrically identical with the same on-state resistance (115Ohm), switching times (600ns/450ns), and supply voltage specifications. The difference is packaging format and reel configuration for automated assembly. ADG211AKRZ-REEL7 has higher inventory availability (17,240 pcs vs. 1,249 pcs).

Q: When should I use DG211DY+ instead of DG211CSE+? A: Both parts have identical electrical specifications (175Ohm on-state resistance, 1µs/500ns switching times, ±4.5V ~ 18V dual supply). DG211DY+ supports the extended operating temperature range (-40°C ~ 85°C) compared to DG211CSE+ (0°C ~ 70°C). Select DG211DY+ for applications requiring low-temperature operation below 0°C or high-temperature operation above 70°C.

Q: Is MAX4604CSE+ compatible with DG211BDY applications? A: MAX4604CSE+ is not a direct replacement. It features significantly lower on-state resistance (4Ohm vs. 85Ohm), faster switching times (120ns/130ns vs. 300ns/200ns), and higher charge injection (225pC vs. 1pC). Use MAX4604CSE+ only when your application requires low-resistance switching and can operate within 0°C ~ 70°C temperature range and 4.5V ~ 36V single supply or ±4.5V ~ 20V dual supply.

Q: Are all substitute parts RoHS compliant? A: Yes. All substitute parts listed are RoHS3 compliant. The original DG211BDY is RoHS non-compliant. For applications requiring RoHS compliance, use DG211BDY-E3, DG201BDY-E3, or any Analog Devices Inc./Maxim Integrated alternative.

Q: What packaging options are available for high-volume production? A: Tape & Reel (TR) packaging is available for ADG211AKRZ-REEL, ADG211AKRZ-REEL7, DG211CSE+T, and DG211DY+T. Tube packaging is available for all other substitute parts. Select Tape & Reel format for automated assembly processes.
