Engineering Selection Recommendations
For Direct Replacement (Identical Electrical Performance): MAX4622ESE+ is the primary choice for applications requiring identical electrical specifications to the obsolete MAX4622ESE. This part maintains the same DPST configuration, 5Ohm on-state resistance, and supply voltage ranges. The MAX4622ESE+ carries active product status and RoHS3 compliance, addressing regulatory requirements for new designs. Packaging options (Tube) differ from the original, requiring PCB assembly process adjustments.
For Alternative Designs (Functional Substitution with Performance Trade-offs): The DG403 series (Vishay Siliconix and Renesas variants) offers active product status and RoHS3 compliance with different electrical characteristics. These parts feature higher on-state resistance (45Ohm vs. 5Ohm), faster switching times, and lower charge injection. Selection between DG403DY-E3/DG403DY-T1-E3 (SPST-NO/NC) and DG403DYZ/DG403DYZ-T (SPDT) depends on circuit topology requirements. Packaging variants (Tube vs. Cut Tape & Digi-Reel®) accommodate different procurement and assembly workflows.
Compliance Considerations: All substitute parts except the original MAX4622ESE are RoHS3 compliant, meeting current environmental regulations. Moisture sensitivity levels vary: MAX4622ESE+ and Vishay DG403 variants maintain MSL 1 (Unlimited), while Renesas DG403DYZ variants specify MSL 3 (168 Hours), requiring controlled storage and handling procedures.
Frequently Asked Questions (FAQ)
Q: Can MAX4622ESE+ be used as a direct replacement for MAX4622ESE? A: Yes. MAX4622ESE+ provides identical electrical specifications including DPST configuration, 5Ohm on-state resistance, and supply voltage ranges (4.5V ~ 36V single, ±4.5V ~ 18V dual). The primary difference is product status (Active vs. Obsolete) and packaging format (Tube). PCB assembly processes may require adjustment for the new packaging.
Q: What are the key differences between MAX4622ESE and DG403 series substitutes? A: The DG403 series differs in switch circuit topology (SPST-NO/NC or SPDT vs. DPST), on-state resistance (45Ohm vs. 5Ohm), and supply voltage ranges. DG403 variants offer faster switching times (150ns vs. 250ns) and lower charge injection (60pC vs. 480pC). These differences require circuit-level evaluation for compatibility.
Q: Which DG403 variant should be selected: Vishay or Renesas? A: Both manufacturers offer functionally equivalent parts in 16-SOIC packages. Vishay DG403DY-E3/DG403DY-T1-E3 (SPST-NO/NC) and Renesas DG403DYZ/DG403DYZ-T (SPDT) differ in switch circuit configuration. Selection depends on circuit topology requirements. Renesas variants specify MSL 3 (168 Hours) versus Vishay MSL 1 (Unlimited), affecting storage and handling procedures.
Q: Are packaging variants (Tube vs. Cut Tape & Digi-Reel®) electrically equivalent? A: Yes. Packaging variants within each part number (e.g., DG403DY-E3 vs. DG403DY-T1-E3) are electrically identical. Differences are limited to packaging format and procurement workflow. Selection depends on assembly line requirements and inventory management practices.
Q: What is the impact of higher on-state resistance in DG403 substitutes? A: DG403 series parts feature 45Ohm on-state resistance compared to 5Ohm in MAX4622ESE. This 9x increase affects signal attenuation, power dissipation, and impedance matching in analog signal switching applications. Circuit-level analysis is required to determine compatibility with specific application requirements.
Q: Do all substitute parts meet current RoHS compliance requirements? A: All substitute parts (MAX4622ESE+, DG403DY-E3, DG403DY-T1-E3, DG403DYZ, DG403DYZ-T) are RoHS3 compliant. The original MAX4622ESE is RoHS non-compliant. Compliance status is a key factor for new designs and production transitions.
Q: What moisture sensitivity considerations apply to these parts? A: MAX4622ESE+, DG403DY-E3, and DG403DY-T1-E3 specify MSL 1 (Unlimited), requiring no special moisture control. Renesas DG403DYZ and DG403DYZ-T specify MSL 3 (168 Hours), requiring controlled storage at specified humidity levels and bake-out procedures before reflow soldering.
