Substitute Part Grouping Explanation

Substitution for the MAX393ESE is determined by the following critical parameters: switch circuit configuration (SPST NO/NC), number of circuits (4), multiplexer circuit ratio (1:1), package type (16-SOIC), and mounting method (surface mount). All substitute parts must maintain identical circuit topology and physical package dimensions to ensure direct PCB compatibility.

The substitute parts are grouped into two categories:

Direct Equivalent (Same Base Specifications): MAX393ESE+ maintains identical electrical specifications to the main part, including 35Ohm on-state resistance, 3V to 15V single supply voltage range, and ±3V to ±8V dual supply voltage range. The primary distinction is product status (active versus obsolete) and RoHS compliance.

Manufacturer-Recommended Alternatives (Enhanced Specifications): ADG1313YRZ and ADG1313YRZ-REEL7 provide the same circuit topology and package but with enhanced electrical performance characteristics, including lower on-state resistance (200Ohm maximum), improved channel-to-channel matching (5Ohm versus 300mOhm), extended operating temperature range (-40°C to 105°C), and higher crosstalk rejection (-90dB @ 1MHz). These parts operate at different supply voltages (12V single supply, ±15V dual supply) and require voltage compatibility verification in the target application.

Engineering Selection Recommendations

MAX393ESE+ Selection: This part is the direct equivalent replacement for MAX393ESE applications. It maintains identical electrical specifications and supply voltage ranges, ensuring drop-in compatibility. MAX393ESE+ is classified as active product status with ROHS3 compliance, making it suitable for new designs and production environments where RoHS compliance is required. This part is available in tube packaging.

ADG1313YRZ and ADG1313YRZ-REEL7 Selection: These parts are manufacturer-recommended alternatives when supply voltage compatibility can be accommodated. Both parts require 12V single supply or ±15V dual supply operation, differing from the MAX393ESE's 3V to 15V single supply range. The ADG1313 series provides enhanced performance with lower on-state resistance (200Ohm), superior channel-to-channel matching (5Ohm), extended operating temperature range (-40°C to 105°C), and improved crosstalk rejection (-90dB @ 1MHz). Both ADG1313 variants are active products with ROHS3 compliance. ADG1313YRZ is supplied in tube packaging, while ADG1313YRZ-REEL7 is supplied in tape and reel format for high-volume production.

Frequently Asked Questions (FAQ)

Q: Can MAX393ESE+ be used as a direct replacement for MAX393ESE?

A: Yes. MAX393ESE+ maintains identical electrical specifications, supply voltage ranges, and 16-SOIC package dimensions. The primary differences are product status (active versus obsolete) and RoHS compliance (ROHS3 compliant versus non-compliant). No circuit modifications are required.

Q: What are the key differences between MAX393ESE and ADG1313YRZ?

A: The primary differences are on-state resistance (35Ohm versus 200Ohm), supply voltage requirements (3V to 15V single supply versus 12V single supply), channel-to-channel matching (300mOhm versus 5Ohm), operating temperature range (-40°C to 85°C versus -40°C to 105°C), and crosstalk performance (-85dB versus -90dB @ 1MHz). Both maintain identical circuit topology (SPST NO/NC, 4 circuits, 1:1 multiplexer) and 16-SOIC package.

Q: Can ADG1313YRZ be used in applications designed for MAX393ESE?

A: ADG1313YRZ can be used only if the application's power supply can accommodate 12V single supply or ±15V dual supply operation. The higher on-state resistance (200Ohm) may affect signal attenuation in low-impedance switching applications. Circuit analysis is required to confirm compatibility.

Q: What is the difference between ADG1313YRZ and ADG1313YRZ-REEL7?

A: Both parts are electrically identical. The difference is packaging format: ADG1313YRZ is supplied in tube packaging, while ADG1313YRZ-REEL7 is supplied in tape and reel format. Selection depends on production volume and assembly equipment requirements.

Q: Are all substitute parts RoHS compliant?

A: MAX393ESE is RoHS non-compliant. MAX393ESE+, ADG1313YRZ, and ADG1313YRZ-REEL7 are all ROHS3 compliant. For applications requiring RoHS compliance, use MAX393ESE+, ADG1313YRZ, or ADG1313YRZ-REEL7.

Q: What is the moisture sensitivity level for these parts?

A: All parts (MAX393ESE, MAX393ESE+, ADG1313YRZ, and ADG1313YRZ-REEL7) have Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling.
