Engineering Selection Recommendations

MAX339ESE+ (Direct Equivalent): This part is the primary replacement for the obsolete MAX339ESE. It maintains identical electrical specifications and 16-SOIC package configuration. The MAX339ESE+ is active in production with ROHS3 compliance, addressing regulatory requirements that the original part does not meet. Inventory availability is higher (6236 pcs) compared to the original part. Selection of MAX339ESE+ is appropriate for designs requiring exact electrical parameter matching and active product support.

DG409DY-E3 and DG409DY-T1-E3 (Vishay Siliconix Substitutes): These parts are manufacturer-recommended alternatives offering improved performance in specific parameters: on-state resistance is reduced to 100Ohm (versus 400Ohm), and switch time is improved to 150ns (versus 500ns). Both parts maintain the SP4T 4:1 dual-circuit configuration and 16-SOIC package. The primary trade-offs are increased channel-to-channel matching tolerance (15Ohm max versus 4Ohm), increased charge injection (20pC versus 1.5pC), increased channel capacitance, and increased leakage current (500pA versus 20pA). Both DG409 variants are ROHS3 compliant and active in production. The DG409DY-T1-E3 offers higher inventory (15600 pcs) in Cut Tape packaging, while DG409DY-E3 is available in Tube packaging (2000 pcs). Selection of DG409 variants is appropriate when improved switching speed and reduced on-state resistance provide system-level benefits that offset the increased leakage and capacitance characteristics.

Frequently Asked Questions (FAQ)

Q: Can MAX339ESE+ be used as a direct replacement for MAX339ESE? A: Yes. The MAX339ESE+ maintains identical electrical specifications, package configuration, and functional characteristics. The primary difference is product status (active versus obsolete) and RoHS compliance (ROHS3 versus non-compliant). No circuit modifications are required.

Q: What are the key differences between MAX339ESE and the DG409DY variants? A: The DG409DY-E3 and DG409DY-T1-E3 offer lower on-state resistance (100Ohm versus 400Ohm) and faster switching times (150ns versus 500ns). However, they exhibit higher leakage current (500pA versus 20pA), increased charge injection (20pC versus 1.5pC), and higher channel capacitance. These differences may affect signal integrity in low-level analog applications or high-impedance circuits.

Q: Are the DG409DY variants pin-compatible with MAX339ESE? A: Yes. Both the DG409DY-E3 and DG409DY-T1-E3 use the same 16-SOIC package and maintain SP4T 4:1 dual-circuit configuration. Pin-level compatibility is maintained, allowing direct PCB substitution without layout modifications.

Q: What is the difference between DG409DY-E3 and DG409DY-T1-E3? A: Both parts are electrically identical. The difference is packaging format: DG409DY-E3 is supplied in Tube packaging, while DG409DY-T1-E3 is supplied in Cut Tape (CT) & Digi-Reel® format. Selection depends on assembly process requirements and inventory management preferences.

Q: Should I use MAX339ESE+ or DG409DY variants for new designs? A: Selection depends on application requirements. Use MAX339ESE+ for designs requiring exact electrical parameter matching and active Analog Devices support. Use DG409DY variants when improved switching speed and reduced on-state resistance provide measurable system benefits and when the increased leakage current and capacitance are acceptable for the application.

Q: Are all substitute parts RoHS compliant? A: MAX339ESE is RoHS non-compliant. MAX339ESE+, DG409DY-E3, and DG409DY-T1-E3 are all ROHS3 compliant. For applications requiring RoHS compliance, any of the three substitute parts are suitable.
