MAX4622CSE Equivalent & Substitute Parts

Part Overview

The MAX4622CSE is a dual-circuit IC switch manufactured by Analog Devices Inc./Maxim Integrated, configured as a DPST (Double Pole Single Throw) switch with 1:1 multiplexer/demultiplexer functionality. This component operates across a wide supply voltage range (4.5V to 36V single supply, or ±4.5V to ±18V dual supply) and features low on-state resistance of 5Ohm with 250ns/200ns switching times. The MAX4622CSE is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production support. Substitute parts must maintain functional compatibility while meeting current manufacturing and compliance standards.

Substitute Part Grouping Explanation

Substitution for the MAX4622CSE is determined by the following critical parameters:

Mandatory Compatibility Criteria:

Package / Case: 16-SOIC (0.154", 3.90mm Width) — all substitutes must use identical package
Mounting Type: Surface Mount
Number of Circuits: 2
Multiplexer/Demultiplexer Circuit: 1:1 or 2:1 (functionally compatible)
Supply Voltage Range: Must support the application's operating voltage
Operating Temperature Range: Must encompass or exceed 0°C ~ 70°C

Allowable Parameter Variations:

On-State Resistance: Substitutes with higher resistance (up to 45Ohm) are acceptable if circuit design permits
Switch Time: Faster switching times are acceptable; slower times require circuit validation
Charge Injection and Channel Capacitance: Variations acceptable within circuit tolerance
Crosstalk: Better performance (-90dB) is acceptable

Substitutes are grouped into two categories: direct replacements (same electrical characteristics) and functional alternatives (different switch circuit topology or resistance, requiring design review).

Engineering Selection Recommendations

Category 1: Direct Replacement (Identical Electrical Characteristics)

MAX4622CSE+ is the direct successor to the MAX4622CSE. Both parts share identical electrical specifications (5Ohm on-state resistance, DPST configuration, 1:1 multiplexer circuit, and matching supply voltage ranges). The primary difference is product status: MAX4622CSE+ is active and ROHS3 compliant, whereas MAX4622CSE is obsolete and RoHS non-compliant. For new designs and production continuity, MAX4622CSE+ is the preferred choice.

Category 2: Functional Alternatives (Different Switch Topology or Resistance)

DG403DY-E3, DG403DY-T1-E3, DG403DYZ, and DG403DYZ-T are functionally compatible alternatives from Vishay Siliconix and Renesas Electronics Corporation. These parts differ in the following aspects:

Switch Circuit: DG403 series uses SPST (Single Pole Single Throw) or SPDT (Single Pole Double Throw) configurations, compared to the DPST configuration of MAX4622CSE
On-State Resistance: DG403 series has 45Ohm maximum resistance, compared to 5Ohm for MAX4622CSE
Multiplexer Circuit: DG403DYZ and DG403DYZ-T use 2:1 multiplexer configuration, compared to 1:1 for MAX4622CSE
Supply Voltage Range: DG403DY series (13V ~ 36V single supply) has a narrower lower voltage limit than MAX4622CSE (4.5V ~ 36V)
Operating Temperature: DG403 series supports -40°C ~ 85°C, exceeding MAX4622CSE's 0°C ~ 70°C range
Crosstalk Performance: DG403 series achieves -90dB @ 1MHz, superior to MAX4622CSE's -60dB @ 1MHz
Charge Injection and Channel Capacitance: DG403 series exhibits lower values (60pC and 12pF respectively), compared to MAX4622CSE (480pC and 34pF)

All substitute parts are ROHS3 compliant and active products. DG403DY-E3 and DG403DY-T1-E3 have MSL 1 (Unlimited), while DG403DYZ and DG403DYZ-T have MSL 3 (168 Hours).

Selection between alternatives depends on circuit requirements: if 5Ohm resistance and DPST topology are mandatory, use MAX4622CSE+. If higher resistance and different switch topology are acceptable, DG403 series parts offer superior performance characteristics and broader temperature range.

Frequently Asked Questions (FAQ)

Q: Can MAX4622CSE+ be used as a direct replacement for MAX4622CSE?

A: Yes. MAX4622CSE+ is the active successor to MAX4622CSE with identical electrical specifications. Both feature 5Ohm on-state resistance, DPST configuration, 1:1 multiplexer circuit, and matching supply voltage ranges (4.5V ~ 36V single supply, ±4.5V ~ ±18V dual supply). The primary difference is compliance status: MAX4622CSE+ is ROHS3 compliant and active, while MAX4622CSE is obsolete and RoHS non-compliant.

Q: What are the key differences between MAX4622CSE and DG403 series parts?

A: The primary differences are on-state resistance (5Ohm vs. 45Ohm), switch circuit topology (DPST vs. SPST/SPDT), and multiplexer configuration (1:1 vs. 2:1 for DG403DYZ variants). DG403 series also offers superior crosstalk performance (-90dB vs. -60dB @ 1MHz), lower charge injection (60pC vs. 480pC), and extended operating temperature range (-40°C ~ 85°C vs. 0°C ~ 70°C). Supply voltage ranges differ: DG403DY series minimum is 13V (vs. 4.5V for MAX4622CSE).

Q: Are DG403 series parts suitable substitutes if my circuit requires 5Ohm on-state resistance?

A: No. DG403 series parts have 45Ohm maximum on-state resistance, which is incompatible with circuits designed for 5Ohm resistance. Use MAX4622CSE+ for applications requiring low resistance switching. DG403 series are suitable only if circuit design permits higher resistance operation.

Q: What is the difference between DG403DY-E3 and DG403DY-T1-E3?

A: Both parts have identical electrical specifications. The difference is packaging: DG403DY-E3 is supplied in Tube packaging, while DG403DY-T1-E3 is supplied in Cut Tape (CT) & Digi-Reel® format. Select based on assembly process requirements.

Q: What is the difference between DG403DYZ and DG403DYZ-T?

A: Both parts have identical electrical specifications. The difference is packaging: DG403DYZ is supplied in Tube packaging, while DG403DYZ-T is supplied in Cut Tape (CT) & Digi-Reel® format. Select based on assembly process requirements.

Q: Do all substitute parts support the same supply voltage range as MAX4622CSE?

A: No. MAX4622CSE supports 4.5V ~ 36V single supply and ±4.5V ~ ±18V dual supply. DG403DY-E3 and DG403DY-T1-E3 support 13V ~ 36V single supply and ±7V ~ ±22V dual supply (narrower lower voltage limit). DG403DYZ and DG403DYZ-T support 5V ~ 34V single supply and ±5V ~ ±17V dual supply. Verify supply voltage compatibility before substitution.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts (MAX4622CSE+, DG403DY-E3, DG403DY-T1-E3, DG403DYZ, DG403DYZ-T) are ROHS3 compliant. The original MAX4622CSE is RoHS non-compliant.

Q: What is the Moisture Sensitivity Level (MSL) difference between substitute parts?

A: MAX4622CSE+ has MSL 1 (Unlimited), matching the original MAX4622CSE. DG403DY-E3 and DG403DY-T1-E3 also have MSL 1 (Unlimited). DG403DYZ and DG403DYZ-T have MSL 3 (168 Hours), requiring controlled storage and handling conditions. Select based on manufacturing environment and storage requirements.

Q: Can I use DG403DYZ (2:1 multiplexer) in place of MAX4622CSE (1:1 multiplexer)?

A: Functional compatibility depends on circuit design. DG403DYZ has 2:1 multiplexer configuration compared to MAX4622CSE's 1:1 configuration. If the circuit is designed for 1:1 operation, DG403DYZ substitution requires design review and validation. Consult application schematics and functional requirements before substitution.

Q: What is the operating temperature range for each substitute part?

A: MAX4622CSE and MAX4622CSE+ operate at 0°C ~ 70°C. DG403DY-E3, DG403DY-T1-E3, DG403DYZ, and DG403DYZ-T all operate at -40°C ~ 85°C, providing extended temperature range capability.
