Substitute Part Grouping Explanation

Substitution of the DG613DJ is determined by the following critical parameters: SPST switch circuit configuration, 4-circuit count, 1:1 multiplexer/demultiplexer topology, 16-DIP through-hole package, and operating temperature range of -40°C to 85°C. On-state resistance, channel matching, supply voltage ranges, switching times, and leakage current are secondary parameters that define performance compatibility within application-specific requirements.

Substitute parts are grouped into three categories based on on-state resistance:

Low Resistance Group (2.5Ohm): MAX4603EPE+ and MAX4663CPE+ offer significantly lower on-state resistance, suitable for applications requiring minimal signal attenuation and lower power dissipation.

Medium Resistance Group (10Ohm to 35Ohm): DG413CJ+, DG413DJ+, DG413DJZ, MAX314CPE+, MAX314EPE+, MAX353CPE+, MAX353EPE+, and MAX4613EPE+ span resistance values from 10Ohm to 70Ohm, providing direct functional equivalence across various supply voltage and temperature specifications.

High Resistance Group (70Ohm): MAX4613EPE+ represents the highest resistance option, applicable where impedance matching or specific circuit requirements demand elevated on-state resistance.

All substitute parts maintain the 16-DIP through-hole package format, SPST-NO/NC switch configuration, and 4-circuit architecture. All active substitutes are RoHS3 compliant, addressing the obsolescence and compliance limitations of the original DG613DJ.

Engineering Selection Recommendations

Direct Functional Equivalents (Preferred for Obsolescence Replacement):

DG413DJ+ and MAX353EPE+ are the primary recommended substitutes. Both maintain 45Ohm and 35Ohm on-state resistance respectively, matching the DG613DJ's electrical characteristics. DG413DJ+ is manufactured by Analog Devices Inc./Maxim Integrated and operates across -40°C to 85°C with ROHS3 compliance. MAX353EPE+ offers identical temperature range and compliance status with 35Ohm resistance and 2Ohm channel matching, directly comparable to the original part.

Extended Supply Voltage Compatibility:

DG413DJZ (Renesas Electronics Corporation) extends single supply voltage range to 5V–44V and dual supply to ±5V–±20V, providing broader application flexibility while maintaining 35Ohm on-state resistance and full temperature range operation (-40°C to 85°C). This part is suitable for designs requiring wider supply voltage tolerance.

Lower Resistance Alternatives:

MAX314EPE+ (10Ohm) and MAX4603EPE+ (2.5Ohm) reduce on-state resistance for applications requiring lower signal attenuation and improved bandwidth performance. MAX314EPE+ maintains the full -40°C to 85°C temperature range. MAX4603EPE+ offers the lowest resistance with extended supply voltage range (4.5V–36V) but exhibits higher charge injection (120pC) and increased channel capacitance.

Temperature-Constrained Applications:

MAX314CPE+, MAX353CPE+, and MAX4663CPE+ operate within 0°C to 70°C temperature range. These parts are suitable only for applications not requiring full -40°C to 85°C operation.

All substitute parts are RoHS3 compliant and active in production, addressing the obsolescence status and regulatory compliance limitations of the DG613DJ.

Frequently Asked Questions (FAQ)

Q: Can I directly replace DG613DJ with DG413DJ+ without circuit modifications?

A: DG413DJ+ is a direct functional equivalent with identical 45Ohm on-state resistance, 4-circuit SPST configuration, and 16-DIP package. The extended supply voltage range (10V–30V single, ±4.5V–±20V dual) is backward compatible with the DG613DJ's original specifications (10V–18V single, ±10V–±15V dual). No circuit modifications are required.

Q: What is the difference between MAX353EPE+ and MAX353CPE+?

A: Both parts are electrically identical with 35Ohm on-state resistance and 2Ohm channel matching. The primary difference is operating temperature range: MAX353EPE+ operates -40°C to 85°C, while MAX353CPE+ is limited to 0°C to 70°C. Select MAX353EPE+ for full industrial temperature range applications.

Q: Why do some substitutes have lower on-state resistance (2.5Ohm vs. 45Ohm)?

A: Lower on-state resistance reduces signal attenuation and power dissipation in switching applications. MAX4603EPE+ and MAX4663CPE+ with 2.5Ohm resistance are suitable for high-frequency or low-impedance signal routing where the DG613DJ's 45Ohm resistance may introduce unacceptable insertion loss. Selection depends on application-specific impedance requirements.

Q: Are all substitute parts available in the same 16-DIP package?

A: Yes. All listed substitute parts are housed in 16-DIP (0.300", 7.62mm) through-hole packages, maintaining mechanical and electrical compatibility with the original DG613DJ footprint.

Q: Which substitute offers the best crosstalk performance?

A: MAX4613EPE+ provides the lowest crosstalk at -100dB @ 1MHz, compared to the DG613DJ's -87dB @ 10MHz. This superior isolation is achieved through optimized channel capacitance (4pF) and is suitable for applications requiring minimal cross-channel signal coupling.

Q: Can I use MAX4603EPE+ in a design originally specified for DG613DJ?

A: MAX4603EPE+ is functionally compatible but exhibits significantly different electrical characteristics: 2.5Ohm resistance (vs. 45Ohm), 120pC charge injection (vs. 4pC), and 55pF channel capacitance (vs. 3pF/2pF). Circuit performance will differ substantially. Use only if the application tolerates or benefits from these parameter changes.

Q: What is the significance of RoHS3 compliance for substitute selection?

A: All active substitute parts are RoHS3 compliant, meeting current environmental and regulatory requirements. The original DG613DJ is RoHS non-compliant, making compliant substitutes necessary for new designs and procurement in regulated markets.
