Substitution Groups:

Group 1: Direct Electrical Equivalents (100Ohm On-State Resistance) MAX399CSE+, MAX399CSE+T, MAX399ESE+, and MAX399ESE+T are direct functional equivalents with identical on-state resistance (100Ohm), matching channel-to-channel matching (6Ohm Max), and equivalent electrical performance. These parts differ only in packaging format (Tube vs. Tape & Reel) and operating temperature range. All maintain SP4T 2-circuit 4:1 configuration in 16-SOIC packages.

Group 2: Higher On-State Resistance Alternatives (200Ohm) ADG1209YRZ and ADG1209YRZ-REEL7 provide 200Ohm on-state resistance with improved performance characteristics including faster switch times (95ns/100ns vs. 150ns/150ns), higher bandwidth (550MHz), and lower charge injection (0.4pC vs. 2.8pC). These maintain SP4T 2-circuit 4:1 configuration but require voltage supply adjustment (5V ~ 16.5V minimum vs. 3V minimum).

Group 3: Higher On-State Resistance Alternative (210Ohm) ADG1309BRZ-REEL7 offers 210Ohm on-state resistance with enhanced leakage performance (1nA vs. 50nA) and operates across 5V ~ 16.5V supply range. This part maintains SP4T 2-circuit 4:1 configuration in 16-SOIC package.

Group 4: Higher On-State Resistance Alternative (350Ohm) MAX355EWE+ provides 350Ohm on-state resistance with extended supply voltage range (4.5V ~ 36V single, ±4.5V ~ 18V dual) and maintains SP4T 2-circuit 4:1 configuration. This part is suitable for applications requiring higher voltage operation.

Group 5: Single-Circuit Alternative (400Ohm) MAX4709ESE+ is a 1-circuit 4:1 multiplexer with 400Ohm on-state resistance. This part differs fundamentally in circuit count (1 vs. 2) and is applicable only to applications requiring single-circuit switching.

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance): MAX399ESE+ or MAX399ESE+T are recommended as primary substitutes. Both maintain identical on-state resistance (100Ohm), matching channel-to-channel matching (6Ohm Max), and equivalent crosstalk performance (-92dB @ 100kHz). These parts are active products with ROHS3 compliance and MSL 1 rating. MAX399ESE+ operates across -40°C to 85°C, while MAX399ESE+T provides identical performance in Tape & Reel packaging. Both are available in higher inventory quantities (8252 and 10347 units respectively).

For Applications Requiring Lower On-State Resistance and Faster Switching: ADG1209YRZ or ADG1209YRZ-REEL7 provide 200Ohm on-state resistance with improved switching performance (95ns/100ns vs. 150ns/150ns). These parts require minimum supply voltage of 5V (vs. 3V for PS399CSE) and operate across extended temperature range (-40°C to 125°C). ADG1209YRZ-REEL7 offers significantly higher inventory (42165 units).

For Applications Requiring Extended Supply Voltage Range: MAX355EWE+ supports supply voltages up to 36V single supply (vs. 15V for PS399CSE) and ±18V dual supply (vs. ±8V for PS399CSE). This part maintains SP4T 2-circuit 4:1 configuration with 350Ohm on-state resistance and is suitable for high-voltage applications.

For Single-Circuit Applications: MAX4709ESE+ is applicable only when single-circuit 4:1 multiplexing is required. This part is not a direct substitute due to circuit count difference (1 vs. 2).

All recommended substitutes maintain ROHS3 compliance and MSL 1 rating consistent with the original PS399CSE specification.

Frequently Asked Questions (FAQ)

Q: Can MAX399CSE+ directly replace PS399CSE in all applications? A: MAX399CSE+ maintains identical electrical specifications including on-state resistance (100Ohm), channel-to-channel matching (6Ohm Max), supply voltage range (3V ~ 15V single, ±3V ~ 8V dual), and crosstalk performance (-92dB @ 100kHz). The primary difference is package case dimension (0.154" vs. 0.295" width) and operating temperature range (0°C ~ 70°C vs. unspecified for PS399CSE). Verify PCB layout compatibility with the smaller package footprint before substitution.

Q: What is the difference between MAX399CSE+, MAX399CSE+T, MAX399ESE+, and MAX399ESE+T? A: All four parts share identical electrical specifications (100Ohm on-state resistance, 2-circuit SP4T 4:1 configuration). Differences are: MAX399CSE+ and MAX399ESE+ are supplied in Tube packaging; MAX399CSE+T and MAX399ESE+T are supplied in Tape & Reel (TR) packaging. MAX399CSE variants operate 0°C ~ 70°C; MAX399ESE variants operate -40°C ~ 85°C. Select based on operating temperature requirements and packaging preference.

Q: Why does ADG1209YRZ require 5V minimum supply voltage while PS399CSE operates at 3V? A: ADG1209YRZ is designed for higher supply voltage operation (5V ~ 16.5V) and provides improved performance characteristics including faster switching times (95ns/100ns vs. 150ns/150ns), higher bandwidth (550MHz), and lower charge injection (0.4pC vs. 2.8pC). Applications operating below 5V supply voltage cannot use ADG1209YRZ and must select from the MAX399 family or MAX355EWE+.

Q: Is MAX4709ESE+ a suitable substitute for PS399CSE? A: MAX4709ESE+ is not a direct substitute. While both are 4:1 multiplexers in 16-SOIC packages, MAX4709ESE+ contains only 1 circuit versus 2 circuits in PS399CSE. This part is applicable only to applications requiring single-circuit switching functionality.

Q: What are the package dimension differences between substitute parts? A: PS399CSE uses 16-SOIC (0.295", 7.50mm width). MAX399 family parts use 16-SOIC (0.154", 3.90mm width), which is a narrower package. ADG1209 and ADG1309 also use 16-SOIC (0.154", 3.90mm width). MAX355EWE+ uses 16-SOIC (0.295", 7.50mm width), matching PS399CSE package width. Verify PCB footprint compatibility before selecting substitutes with different package dimensions.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All substitute parts listed (MAX399 family, ADG1209 family, ADG1309BRZ-REEL7, and MAX355EWE+) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, consistent with PS399CSE specifications.
