Substitute Part Grouping Explanation
Substitution eligibility for the MAX4558EEE+ is determined by the following critical parameters:
Primary Substitution Criteria:
- Multiplexer/Demultiplexer circuit configuration: 8:1 (mandatory)
- Number of circuits: 1 (mandatory)
- Supply voltage compatibility: Must support at least the application's required voltage range within 2V ~ 12V single supply or ±2V ~ 6V dual supply envelope
- On-state resistance: Lower or equal values are acceptable; higher values may impact signal integrity
- Operating temperature range: Must encompass the application's operating conditions
- Package compatibility: Surface mount packages with equivalent or compatible pinouts
Secondary Compatibility Factors:
- Switch time characteristics (Ton, Toff): Faster switching is acceptable; slower switching may limit bandwidth
- Charge injection and channel capacitance: Lower values improve signal fidelity
- Leakage current: Lower values reduce noise floor
- Crosstalk performance: Lower crosstalk (more negative dB values) improves channel isolation
Substitute parts are grouped by their adherence to these parameters. Parts with identical 8:1 multiplexer configuration and compatible supply voltage ranges qualify as direct substitutes. Variations in on-state resistance, switching speed, and package form factor create performance and mechanical trade-offs that must be evaluated against specific application requirements.

Engineering Selection Recommendations
Active Product Status Substitutes: The ADG658YRQZ, ADG658YRQZ-REEL7, ADG658YRUZ, and ADG658YRUZ-REEL7 are all active products from Analog Devices Inc. with full supply voltage compatibility (2V ~ 12V single, ±2V ~ 6V dual) matching the MAX4558EEE+. These parts offer superior on-state resistance (75Ohm versus 160Ohm), lower leakage current (200pA versus 1nA), and extended operating temperature range (-40°C ~ 125°C versus -85°C). The primary trade-off is package selection: YRQZ variants use 16-QSOP (3.90mm width, matching MAX4558EEE+), while YRUZ variants use 16-TSSOP (4.40mm width).
The 74HC4051PW,118 and 74HC4051PW-Q100,11 from Nexperia are active products offering faster switching performance (51ns/42ns versus 150ns/120ns) and lower on-state resistance (120Ohm). However, supply voltage range is restricted to 2V ~ 10V single supply and ±1.5V ~ 5V dual supply, making them unsuitable for applications requiring the full 12V single supply capability of the MAX4558EEE+. The 74HC4051PW-Q100,11 variant includes AEC-Q100 automotive qualification.
The 74HCT4051PW,118 is restricted to 4.5V ~ 5.5V single supply operation and is suitable only for TTL-level applications with fixed 5V supplies.
The CD74HC4051QPWRG4Q1 from Texas Instruments carries Last Time Buy status and includes AEC-Q100 automotive qualification, but restricted supply voltage (2V ~ 6V single) limits its applicability.
Obsolete Product Status: The 74HC4051PW,112 is marked obsolete and should not be selected for new designs despite active inventory availability.
Packaging Considerations: All substitute parts maintain 16-pin surface mount packages. The 3.90mm width packages (MAX4558EEE+, ADG658YRQZ variants) are mechanically compatible. The 4.40mm width packages (74HC4051 variants, ADG658YRUZ variants, CD74HC4051QPWRG4Q1) require PCB layout verification for clearance and thermal management.
Compliance: All listed parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating, matching the MAX4558EEE+ compliance profile.
Frequently Asked Questions (FAQ)
Q: Can I substitute a 74HC4051 series part for the MAX4558EEE+ in all applications?
A: No. The 74HC4051 series has restricted supply voltage ranges (2V ~ 10V single supply maximum) compared to the MAX4558EEE+ (2V ~ 12V). Applications requiring 12V single supply operation cannot use 74HC4051 variants. Additionally, 74HC4051PW,112 is obsolete and unsuitable for new designs.
Q: What is the difference between ADG658YRQZ and ADG658YRUZ?
A: Both parts are electrically identical 8:1 multiplexers from Analog Devices with 75Ohm on-state resistance and full supply voltage compatibility. The difference is packaging: YRQZ uses 16-QSOP (3.90mm width), while YRUZ uses 16-TSSOP (4.40mm width). The -REEL7 suffix indicates cut tape and digi-reel packaging versus tube packaging. Select based on PCB layout requirements and assembly equipment compatibility.
Q: Is the 74HCT4051PW,118 a suitable substitute?
A: Only for applications with fixed 5V supply operation. The 74HCT4051PW,118 is restricted to 4.5V ~ 5.5V single supply and cannot operate across the full 2V ~ 12V range of the MAX4558EEE+. It is not a general-purpose substitute.
Q: Why do some substitute parts have faster switching times?
A: The 74HC4051 series (51ns/42ns) and 74HCT4051 series (39ns/32ns) achieve faster switching through different semiconductor process technology. Faster switching enables higher bandwidth operation (180MHz versus unspecified for MAX4558EEE+) but may introduce increased noise in sensitive analog applications. Evaluate switching speed requirements against signal integrity needs.
Q: Can I use CD74HC4051QPWRG4Q1 in automotive applications?
A: The CD74HC4051QPWRG4Q1 carries AEC-Q100 qualification, making it suitable for automotive-grade applications. However, it is marked Last Time Buy status, indicating discontinued production. For new automotive designs, use 74HC4051PW-Q100,11 (also AEC-Q100 qualified and active) or ADG658 variants if supply voltage requirements permit.
Q: What is the impact of on-state resistance differences?
A: Lower on-state resistance reduces signal attenuation and improves signal-to-noise ratio. The ADG658 series (75Ohm) provides superior performance compared to MAX4558EEE+ (160Ohm) and 74HC4051 variants (120Ohm). For high-impedance signal sources or precision analog applications, lower on-state resistance is advantageous. For digital switching or high-impedance loads, the difference is negligible.
Q: Are all substitute parts RoHS3 compliant?
A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, matching the MAX4558EEE+ compliance profile. MSL rating is 1 (unlimited) for all parts, indicating no moisture sensitivity restrictions during storage or assembly.
