Substitute Part Grouping Explanation
Substitution of the MAX313CUE is determined by the following critical parameters:
Functional Equivalence Requirements:
- Switch circuit topology: SPST - NO
- Number of circuits: 4
- Multiplexer configuration: 1:1
- Package type: 16-TSSOP surface mount
Electrical Compatibility Criteria:
- On-state resistance must not exceed application requirements
- Supply voltage ranges must encompass the original design specifications
- Switching time performance must meet or exceed original specifications
- Operating temperature range must support the intended application environment
Compliance and Availability:
- Product status (active vs. obsolete) affects long-term supply assurance
- RoHS compliance status determines regulatory suitability for new designs
- Packaging format (tube, tape & reel, cut tape) affects procurement and assembly processes
Substitute parts are grouped into two categories: direct equivalents (identical electrical specifications with improved compliance) and functional alternatives (different on-state resistance or supply voltage specifications that remain compatible within defined application parameters).

Engineering Selection Recommendations
Direct Equivalent - Recommended for New Designs:
MAX313CUE+ is the primary substitute for the obsolete MAX313CUE. This part maintains identical electrical specifications (10Ohm on-state resistance, 225ns/185ns switching times, 4.5V to 30V single supply, ±4.5V to ±20V dual supply) while offering active product status and ROHS3 compliance. The MAX313CUE+ is available in tube packaging with 2200 units in stock, providing immediate supply assurance.
Functional Alternatives - Application-Dependent Selection:
ADG452BRUZ and ADG452BRUZ-REEL provide superior performance characteristics with 5Ohm on-state resistance (lower than MAX313CUE), faster switching times (180ns/140ns), and improved crosstalk performance (-90dB @ 1MHz). These parts support extended operating temperature range (-40°C to 85°C) and are available in multiple packaging formats. Selection is appropriate for applications requiring lower on-state resistance and wider temperature operation.
ADG412BRUZ offers 35Ohm on-state resistance with faster switching performance (175ns/145ns) and lower charge injection (5pC). This part operates at fixed 12V single supply and ±15V dual supply, requiring design verification for voltage compatibility. Selection is suitable for fixed-voltage supply applications where higher on-state resistance is acceptable.
DG445DVZ (Renesas Electronics Corporation) provides 85Ohm on-state resistance with the widest single supply voltage range (5V to 34V) and superior crosstalk performance (-100dB @ 1MHz). This part is appropriate for applications requiring extended supply voltage flexibility and minimal crosstalk interference. Available in tube and tape & reel packaging.
Compliance Considerations:
All substitute parts except the original MAX313CUE are ROHS3 compliant, meeting current regulatory requirements for new product designs. The MAX313CUE+ is the only substitute maintaining identical electrical specifications while achieving compliance status.
Frequently Asked Questions (FAQ)
Q: Can MAX313CUE+ directly replace MAX313CUE without circuit modifications?
A: Yes. MAX313CUE+ maintains identical electrical specifications including on-state resistance (10Ohm), supply voltage ranges (4.5V to 30V single, ±4.5V to ±20V dual), switching times (225ns/185ns), and package format (16-TSSOP). The only differences are product status (active vs. obsolete) and RoHS compliance. No circuit modifications are required.
Q: What are the key differences between ADG452BRUZ and MAX313CUE?
A: ADG452BRUZ features lower on-state resistance (5Ohm vs. 10Ohm), faster switching times (180ns/140ns vs. 225ns/185ns), and extended operating temperature range (-40°C to 85°C vs. 0°C to 70°C). Supply voltage specifications differ: ADG452BRUZ operates at fixed 12V single supply and ±4.5V to ±20V dual supply. Selection depends on whether the application can accommodate these electrical differences and requires the extended temperature range.
Q: Is DG445DVZ compatible with MAX313CUE designs?
A: DG445DVZ is functionally compatible as a 4-circuit SPST-NO switch in 16-TSSOP package. However, the 85Ohm on-state resistance is significantly higher than MAX313CUE (10Ohm), which may affect signal integrity and power dissipation in the application. The wider single supply voltage range (5V to 34V) and superior crosstalk performance (-100dB @ 1MHz) make this part suitable for applications where higher on-state resistance is acceptable and extended voltage flexibility is beneficial.
Q: What packaging options are available for substitute parts?
A: MAX313CUE+ is available in tube packaging. ADG412BRUZ is supplied in tube format. ADG452BRUZ is available in tube, tape & reel (TR), and cut tape (CT) & Digi-Reel® formats. DG445DVZ is available in tube and tape & reel (TR) packaging. Selection of packaging format depends on production volume and assembly process requirements.
Q: Are all substitute parts RoHS compliant?
A: Yes. All substitute parts (MAX313CUE+, ADG412BRUZ, ADG452BRUZ, ADG452BRUZ-REEL, ADG452BRUZ-REEL7, DG445DVZ, and DG445DVZ-T) are ROHS3 compliant. The original MAX313CUE is RoHS non-compliant. This compliance status is a primary driver for substitution in new product designs subject to regulatory requirements.
Q: Which substitute part offers the best overall performance?
A: Performance optimization depends on application requirements. ADG452BRUZ provides the lowest on-state resistance (5Ohm) and fastest switching times (180ns/140ns) among active substitutes. DG445DVZ offers the best crosstalk performance (-100dB @ 1MHz) and widest single supply voltage range (5V to 34V). MAX313CUE+ maintains exact electrical equivalence to the original part while providing active status and compliance.
