MAX4604CPE Equivalent & Substitute Parts

Part Overview

The MAX4604CPE is a 4-circuit SPST-NC (Single Pole Single Throw - Normally Closed) analog switch IC manufactured by Analog Devices Inc./Maxim Integrated. This component operates as a 1:1 multiplexer/demultiplexer with 4Ohm on-state resistance and is housed in a 16-DIP package. The MAX4604CPE is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production support. Substitute parts must maintain functional compatibility through matching switch circuit topology, circuit count, package form factor, and electrical performance within acceptable operating ranges.

Substitute Part Grouping Explanation

Substitution for the MAX4604CPE is determined by strict adherence to the following criteria:

Mandatory Compatibility Parameters:

Switch Circuit: SPST - NC (topology must match exactly)
Number of Circuits: 4 (circuit count must be identical)
Multiplexer/Demultiplexer Circuit: 1:1 (configuration must match)
Package / Case: 16-DIP (0.300", 7.62mm) (physical form factor must be identical)
Mounting Type: Through Hole (mounting method must match)

Electrical Performance Parameters (acceptable ranges for substitution):

On-State Resistance (Max): Must not exceed 4Ohm to maintain signal integrity
Voltage - Supply, Single (V+): Must support minimum 4.5V ~ 36V range or be compatible with application requirements
Voltage - Supply, Dual (V±): Must support minimum ±4.5V ~ 20V range or be compatible with application requirements
Operating Temperature: Must support minimum 0°C ~ 70°C range or be compatible with application requirements

Substitute parts are grouped by on-state resistance value, as this parameter directly affects circuit performance and signal fidelity. Parts with lower on-state resistance (closer to 4Ohm) provide superior performance characteristics and are preferred for direct substitution.

Engineering Selection Recommendations

Primary Substitute (Direct Replacement): MAX4604CPE+ is the direct successor to MAX4604CPE. It maintains identical electrical specifications and package configuration while offering Active product status and ROHS3 compliance. This part is the preferred choice for applications requiring no design modification.

Performance-Optimized Substitutes (Low On-State Resistance): ADG451BNZ provides 5Ohm on-state resistance with superior channel matching (100mOhm) and extended operating temperature range (-40°C ~ 85°C). This part is suitable for applications where low on-state resistance and improved temperature performance are beneficial. Supply voltage range is limited to 12V single supply with dual supply support of ±4.5V ~ 20V.

Functional Substitutes (Moderate On-State Resistance): ADG431BNZ (24Ohm), ADG411BNZ (35Ohm), and DG411DJ-E3 (35Ohm) provide functional equivalence with higher on-state resistance values. These parts are suitable for applications where signal attenuation from increased on-state resistance is acceptable. All three parts offer ROHS3 compliance and extended operating temperature range. DG411DJ-E3 provides the widest single supply voltage range (5V ~ 44V).

Alternative Substitutes (Higher On-State Resistance): ADG444BNZ (70Ohm) and DG211BDJ-E3 (85Ohm) provide functional equivalence with significantly higher on-state resistance. These parts are suitable only for applications where signal attenuation is not a limiting factor. Both parts offer superior crosstalk performance (-100dB and -95dB respectively).

Limited Compatibility Substitute: ADG211AKNZ (115Ohm) provides the highest on-state resistance and is suitable only for applications with minimal signal sensitivity requirements. This part requires fixed ±15V dual supply operation and is not recommended for applications requiring the original part's flexible supply voltage range.

All substitute parts listed maintain SPST-NC topology, 4-circuit configuration, 1:1 multiplexer/demultiplexer circuit, 16-DIP package form factor, and through-hole mounting compatibility with the MAX4604CPE.

Frequently Asked Questions (FAQ)

Q: Can MAX4604CPE+ be used as a direct replacement for MAX4604CPE? A: Yes. MAX4604CPE+ is the active production equivalent with identical electrical specifications, package configuration, and pin assignment. The primary difference is product status (Active vs. Obsolete) and RoHS compliance (ROHS3 vs. non-compliant). No design modification is required.

Q: What is the impact of higher on-state resistance in substitute parts? A: On-state resistance directly affects signal attenuation and power dissipation. Parts with higher on-state resistance (ADG431BNZ at 24Ohm, ADG411BNZ at 35Ohm) introduce greater signal loss and generate more heat during operation. Selection depends on application signal levels and thermal constraints. For low-signal applications, on-state resistance becomes a critical parameter.

Q: Are all substitute parts pin-compatible with MAX4604CPE? A: All listed substitute parts maintain the 16-DIP package form factor and through-hole mounting configuration. However, pin assignment compatibility must be verified against specific application schematics. While all parts share identical switch circuit topology (SPST-NC, 4-circuit, 1:1), internal pin routing may differ between manufacturers.

Q: Which substitute part offers the best overall performance? A: ADG451BNZ provides the lowest on-state resistance (5Ohm) among active substitutes, superior channel matching (100mOhm), and extended operating temperature range (-40°C ~ 85°C). However, supply voltage range is limited to 12V single supply. For applications requiring the original part's flexible supply voltage range (4.5V ~ 36V), MAX4604CPE+ remains the optimal choice.

Q: Can substitute parts with different on-state resistance values be mixed in the same circuit? A: Mixing parts with different on-state resistance values in the same circuit is not recommended. Unequal on-state resistance creates channel-to-channel impedance mismatch, introducing signal distortion and crosstalk. Consistent on-state resistance across all switch channels is required for proper circuit operation.

Q: What is the significance of RoHS compliance in substitute selection? A: RoHS compliance indicates lead-free manufacturing and reduced hazardous substance content. MAX4604CPE is RoHS non-compliant (contains lead), while all listed substitute parts are ROHS3 compliant. For new designs and applications subject to environmental regulations, ROHS3-compliant parts are required.

Q: How do operating temperature ranges affect substitute selection? A: MAX4604CPE operates from 0°C ~ 70°C. Most substitute parts extend this range to -40°C ~ 85°C, providing broader environmental compatibility. Applications requiring operation below 0°C or above 70°C must select substitute parts with extended temperature ratings. DG211BDJ-E3 and DG411HSDJ-E3 have restricted lower supply voltage limits that may affect low-temperature performance.

Q: Are Vishay Siliconix and Renesas parts functionally equivalent to Analog Devices parts? A: Yes, within the specified electrical parameters. DG411DJ-E3 (Vishay Siliconix), DG411DJZ (Renesas), and DG211BDJ-E3 (Vishay Siliconix) maintain identical switch circuit topology, circuit count, and package configuration. Electrical performance differs in specific parameters (on-state resistance, leakage current, crosstalk), requiring application-specific evaluation.
