DG211CY Equivalent & Substitute Parts

Part Overview

The DG211CY is a 4-circuit SPST-NC (Single Pole Single Throw - Normally Closed) analog switch IC manufactured by Renesas Electronics Corporation in a 16-SOIC surface mount package. This component features 175Ohm on-state resistance and operates with dual supply voltages of ±15V. The DG211CY is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. Substitute parts must maintain functional compatibility through matching switch architecture, circuit count, on-state resistance tolerance, and package form factor while meeting modern compliance requirements.

Package form factor: 16-SOIC (0.154", 3.90mm Width) required
On-state resistance: Maximum 175Ohm acceptable
Supply voltage compatibility: Must support ±15V dual supply operation
Mounting type: Surface mount required

Substitute parts are grouped into two categories:

Category 1 - Direct Resistance Match (175Ohm): Parts maintaining identical 175Ohm on-state resistance specification. These include DG211CY+, DG211CSE+, and DG211CSE+T. These parts provide the closest electrical equivalence to the original DG211CY.

Category 2 - Lower Resistance Variants (85Ohm to 115Ohm): Parts with reduced on-state resistance including ADG211AKRZ, ADG211AKRZ-REEL, ADG211AKRZ-REEL7, DG211BDY-E3, and DG211BDY-T1-E3.

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Specifications):

DG211CY+ is the primary direct substitute, offering identical 175Ohm on-state resistance and matching switch performance characteristics. This part is manufactured by Analog Devices Inc./Maxim Integrated and carries Active product status with ROHS3 compliance. DG211CSE+ and DG211CSE+T provide equivalent electrical performance with expanded supply voltage range (±4.5V ~ 18V) and are available in Tube and Tape & Reel packaging options respectively.

For Enhanced Performance Applications:

ADG211AKRZ, ADG211AKRZ-REEL, and ADG211AKRZ-REEL7 reduce on-state resistance to 115Ohm while maintaining all other functional parameters. These parts support extended operating temperature range (-40°C ~ 85°C) and include channel-to-channel matching specification (5.75Ohm). Available in Tube and Tape & Reel packaging formats with high inventory levels.

DG211BDY-E3 and DG211BDY-T1-E3 from Vishay Siliconix offer the lowest on-state resistance at 85Ohm with superior leakage current performance (500pA versus 5nA) and improved crosstalk isolation (-95dB). These parts support wider supply voltage range (±4.5V ~ 22V) and extended temperature operation (-40°C ~ 85°C).

Compliance Considerations:

All substitute parts listed carry ROHS3 compliance and REACH Unaffected status, meeting modern regulatory requirements. The original DG211CY is RoHS non-compliant, making substitution necessary for new designs and production continuity in regulated markets.

Frequently Asked Questions (FAQ)

Q: Can DG211CY+ be used as a direct replacement for DG211CY?

A: Yes. DG211CY+ maintains identical on-state resistance (175Ohm), switch circuit architecture (SPST-NC), circuit count (4), and 16-SOIC package specifications. Both parts support ±15V dual supply operation. DG211CY+ is Active status with ROHS3 compliance, addressing the obsolete status of the original part.

Q: What is the difference between ADG211AKRZ and DG211BDY-E3?

A: Both are functional substitutes with reduced on-state resistance compared to DG211CY. ADG211AKRZ features 115Ohm resistance with 5.75Ohm channel matching, while DG211BDY-E3 offers 85Ohm resistance with superior 2Ohm channel matching. DG211BDY-E3 provides lower leakage current (500pA versus 5nA) and better crosstalk performance (-95dB versus -80dB). Selection depends on application requirements for resistance tolerance and signal isolation.

Q: Are packaging differences between Tube, Tape & Reel, and Cut Tape significant for substitution?

A: Packaging differences affect handling, storage, and assembly processes but do not impact electrical functionality. Tube packaging suits lower-volume applications and manual assembly. Tape & Reel and Cut Tape & Digi-Reel® packaging support automated pick-and-place assembly. Select packaging based on production volume and assembly equipment compatibility.

Q: Can I use ADG211AKRZ-REEL7 in applications designed for DG211CY?

A: Yes, with consideration of electrical differences. ADG211AKRZ-REEL7 maintains the required SPST-NC architecture, 4-circuit configuration, and 16-SOIC package. The reduced on-state resistance (115Ohm versus 175Ohm) and extended operating temperature (-40°C ~ 85°C versus 0°C ~ 70°C) represent performance improvements. Verify that your circuit design accommodates the lower resistance value and wider temperature range.

Q: What is the inventory status for substitute parts?

A: DG211CY+ (775 pcs), DG211CSE+ (1233 pcs), and DG211CSE+T (20,100 pcs) provide direct resistance equivalents. ADG211AKRZ (3302 pcs), ADG211AKRZ-REEL (1249 pcs), and ADG211AKRZ-REEL7 (17,240 pcs) offer lower-resistance alternatives. DG211BDY-E3 (1322 pcs) and DG211BDY-T1-E3 (15,553 pcs) provide the lowest resistance option with highest inventory availability.

Q: Does supply voltage range affect substitution compatibility?

A: The original DG211CY operates at fixed ±15V. Substitute parts with expanded ranges (±4.5V ~ 18V or ±4.5V ~ 22V) remain compatible with ±15V operation. Verify that your power supply design falls within the substitute part's specified voltage range. Wider voltage ranges provide design flexibility for future applications.
