MAX4606CPE Equivalent & Substitute Parts

Part Overview

The MAX4606CPE is a 4-circuit IC switch with SPST NO/NC configuration, manufactured by Analog Devices Inc./Maxim Integrated. This component features a 4Ohm on-state resistance and operates across a wide supply voltage range (4.5V to 36V single supply, or ±4.5V to ±20V dual supply). The device is classified as obsolete, making identification of active equivalent parts essential for new designs and ongoing production support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX4606CPE is determined by the following critical parameters:

Primary Compatibility Criteria:

• Switch circuit configuration (SPST NO/NC capability)
• Number of circuits (4-circuit requirement)
• Multiplexer/demultiplexer circuit topology (1:1)
• Package type (16-DIP form factor)
• Operating temperature range (0°C ~ 70°C)
• Supply voltage compatibility (single or dual supply operation)

Secondary Performance Considerations:

• On-state resistance characteristics
• Channel-to-channel matching tolerance
• Switch timing specifications
• Leakage current performance
• Crosstalk isolation

The two identified substitutes—DG212CJ+ and MAX4663CPE+—maintain the core 4-circuit, 1:1 SPST configuration in identical 16-DIP packaging. Both operate within the same temperature range and are manufactured by the same supplier, ensuring mechanical and electrical compatibility within their respective parameter tolerances.

Engineering Selection Recommendations

MAX4663CPE+ (Preferred Substitute)

The MAX4663CPE+ is the closest functional equivalent to the MAX4606CPE. Both devices maintain SPST NO/NC switch configuration with 4 circuits in 1:1 topology. The MAX4663CPE+ offers superior on-state resistance (2.5Ohm vs. 4Ohm), tighter channel-to-channel matching (100mOhm vs. 200mOhm), and identical supply voltage ranges. The device is currently in active production status with ROHS3 compliance, addressing the regulatory limitations of the obsolete MAX4606CPE. Mechanical compatibility is assured through identical 16-DIP packaging.

DG212CJ+ (Alternative Substitute)

The DG212CJ+ provides a functional alternative for applications where SPST NO-only configuration is acceptable. This device shares the 4-circuit, 1:1 topology and 16-DIP package with the MAX4606CPE. However, the DG212CJ+ exhibits significantly higher on-state resistance (175Ohm), slower switch timing (1µs turn-on), and operates under a slightly reduced dual supply voltage range (±4.5V ~ 18V vs. ±4.5V ~ 20V). The DG212CJ+ is suitable only for low-speed switching applications where resistance and timing specifications do not constrain circuit performance. This device is also ROHS3 compliant and in active production.

Compliance Considerations

Both substitute parts are ROHS3 compliant, addressing environmental and regulatory requirements that the obsolete MAX4606CPE does not meet. Selection between MAX4663CPE+ and DG212CJ+ should prioritize circuit requirements for on-state resistance, switching speed, and supply voltage range.

Frequently Asked Questions (FAQ)

Q: Can the MAX4663CPE+ directly replace the MAX4606CPE in existing designs?

A: Yes, within electrical and mechanical constraints. Both devices feature identical 16-DIP packaging, 4-circuit SPST configuration, and 1:1 multiplexer topology. The MAX4663CPE+ operates across the same supply voltage ranges and temperature specifications. However, the lower on-state resistance (2.5Ohm vs. 4Ohm) and faster switching times may require circuit validation in applications sensitive to these parameters.

Q: What are the key differences between the MAX4663CPE+ and DG212CJ+?

A: The MAX4663CPE+ maintains SPST NO/NC capability identical to the original MAX4606CPE, while the DG212CJ+ provides only SPST NO configuration. The DG212CJ+ exhibits substantially higher on-state resistance (175Ohm) and slower switching performance (1µs turn-on vs. 120ns). The DG212CJ+ is appropriate only for applications where these performance differences do not impact circuit operation.

Q: Are there supply voltage compatibility issues with these substitutes?

A: The MAX4663CPE+ maintains full compatibility with the MAX4606CPE across both single supply (4.5V ~ 36V) and dual supply (±4.5V ~ 20V) ranges. The DG212CJ+ operates under dual supply only (±4.5V ~ 18V), with a 2V reduction in maximum positive supply voltage. Applications requiring single supply operation must use the MAX4663CPE+.

Q: How do the switching time specifications compare?

A: The MAX4606CPE specifies 120ns turn-on and 130ns turn-off. The MAX4663CPE+ is slower at 275ns turn-on and 175ns turn-off. The DG212CJ+ is significantly slower at 1µs turn-on and 500ns turn-off. High-speed switching applications should prioritize the MAX4663CPE+ over the DG212CJ+.

Q: What is the significance of the RoHS compliance difference?

A: The MAX4606CPE is RoHS non-compliant, while both substitutes (MAX4663CPE+ and DG212CJ+) are ROHS3 compliant. For new designs and applications subject to environmental regulations, the compliant substitutes are required.

Q: Can the DG212CJ+ be used in applications originally designed for the MAX4606CPE?

A: Only if the application does not require SPST NO/NC capability and can tolerate the DG212CJ+'s higher on-state resistance (175Ohm) and slower switching times (1µs turn-on). Applications requiring low-resistance switching paths or fast switching performance should use the MAX4663CPE+ instead.
