Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX563CWN are categorized based on the following substitution criteria:

Parametric Equivalent Category: Parts that maintain identical electrical and mechanical specifications, including protocol (RS562), driver/receiver configuration (2/2), duplex mode (Full), package type (18-SOIC), and supply voltage range (3V ~ 3.6V). The MAX563CWN+ falls into this category.

Manufacturer Recommended Category: Parts that share the same package footprint (18-SOIC), mounting type (Surface Mount), and core transceiver functionality (2/2 full-duplex), but operate under a different protocol (RS232) with extended electrical specifications. The ADM3222ARWZ, ADM3222ARWZ-REEL, and ADM3222ARWZ-REEL7 are classified as manufacturer-recommended alternatives due to their active product status and enhanced compliance certifications.

Key parameters determining substitution eligibility:

• Package / Case: 18-SOIC (0.295", 7.50mm Width)
• Mounting Type: Surface Mount
• Number of Drivers/Receivers: 2/2
• Duplex: Full
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Parameter Comparison

Engineering Selection Recommendations

MAX563CWN+ (Parametric Equivalent): The MAX563CWN+ is the direct parametric equivalent, maintaining identical electrical specifications and protocol compatibility with the original MAX563CWN. This part is classified as active and ROHS3 compliant, providing improved regulatory compliance over the obsolete original. Selection of MAX563CWN+ is appropriate for applications requiring strict protocol and electrical parameter matching while benefiting from active product status and enhanced compliance certifications.

ADM3222ARWZ, ADM3222ARWZ-REEL, ADM3222ARWZ-REEL7 (Manufacturer Recommended Alternatives): These parts are manufacturer-recommended alternatives that share identical package footprint, mounting type, and transceiver configuration (2/2 full-duplex). All three variants operate under RS232 protocol with extended supply voltage range (3V ~ 5.5V), wider operating temperature range (-40°C ~ 85°C), and higher data rate capability (460 Kbps). All variants are active products with ROHS3 compliance. Selection among these three is determined by packaging and inventory requirements: ADM3222ARWZ (Tube packaging), ADM3222ARWZ-REEL (Cut Tape & Digi-Reel, 2574 Pcs available), and ADM3222ARWZ-REEL7 (Cut Tape & Digi-Reel, 20200 Pcs available).

Frequently Asked Questions (FAQ)

Q: Can MAX563CWN+ be used as a direct replacement for MAX563CWN? A: Yes. MAX563CWN+ maintains identical electrical specifications, protocol (RS562), driver/receiver configuration (2/2), duplex mode (Full), and package type (18-SOIC). The primary difference is product status (Active vs. Obsolete) and RoHS compliance (ROHS3 vs. non-compliant).

Q: What are the key differences between MAX563CWN and ADM3222ARWZ? A: The primary differences are protocol (RS562 vs. RS232), receiver hysteresis (500 mV vs. 400 mV), data rate (116 Kbps vs. 460 Kbps), supply voltage range (3V ~ 3.6V vs. 3V ~ 5.5V), and operating temperature range (0°C ~ 70°C vs. -40°C ~ 85°C). Package footprint and transceiver configuration remain identical.

Q: Are ADM3222ARWZ, ADM3222ARWZ-REEL, and ADM3222ARWZ-REEL7 electrically identical? A: Yes. All three variants are electrically identical. Differences exist only in packaging format: ADM3222ARWZ is supplied in Tube packaging, while ADM3222ARWZ-REEL and ADM3222ARWZ-REEL7 are supplied in Cut Tape & Digi-Reel format with different inventory quantities.

Q: What is the significance of the 18-SOIC package compatibility? A: The 18-SOIC (0.295", 7.50mm Width) package is identical across all listed parts, ensuring PCB footprint compatibility and eliminating the need for layout redesign during component substitution.

Q: Do all substitute parts meet RoHS compliance requirements? A: MAX563CWN is RoHS non-compliant. MAX563CWN+, ADM3222ARWZ, ADM3222ARWZ-REEL, and ADM3222ARWZ-REEL7 are all ROHS3 compliant.

Q: What is the Moisture Sensitivity Level (MSL) for all parts? A: All parts, including the original MAX563CWN and all substitutes, have MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling.
