Key Parameters

Substitute Part Grouping Explanation

Substitution of the ISL83220ECV-T is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Protocol: RS232
• Number of Drivers/Receivers: 1/1
• Duplex: Full
• Receiver Hysteresis: 300 mV
• Voltage - Supply: 3V ~ 5.5V
• Package / Case: 16-TSSOP (0.173", 4.40mm Width)
• Mounting Type: Surface Mount

Acceptable Variation Parameters:

• Data Rate: Substitute parts may operate at equal or higher data rates (120kbps, 250kbps, or 1Mbps are all acceptable)
• Operating Temperature: Substitute parts may support extended temperature ranges beyond the original 0°C ~ 70°C specification
• Product Status: Active parts are preferred over obsolete parts
• RoHS Compliance: Modern substitutes are RoHS3 compliant

The ICL3221CVZ-T from Renesas Electronics Corporation is a parametric equivalent with identical electrical specifications and active product status. The SP3220 series from MaxLinear, Inc. comprises similar parts with matching core functionality across multiple data rate and temperature variants.

Parameter Comparison

Engineering Selection Recommendations

Primary Equivalent: ICL3221CVZ-T is the direct parametric equivalent from Renesas Electronics Corporation. It maintains identical electrical specifications (250kbps data rate, 300mV receiver hysteresis, 3V–5.5V supply, 0°C–70°C operating range) and identical 16-TSSOP package. The part is active and RoHS3 compliant, providing a drop-in replacement with improved compliance status.

Secondary Substitutes (MaxLinear SP3220 Series): The SP3220 series provides functional equivalence across multiple variants. Selection depends on application requirements:

• SP3220EBCY-L and SP3220EBEY-L/TR: Support 250kbps data rate matching the original specification. SP3220EBEY-L/TR extends operating temperature to -40°C–85°C for wider environmental applications.
• SP3220ECY-L and SP3220ECY-L/TR: Operate at 120kbps, suitable for applications with lower bandwidth requirements.
• SP3220EEY-L/TR and SP3220EUEY-L/TR: Support extended temperature ranges (-40°C–85°C) with data rates of 120kbps and 1Mbps respectively, enabling higher-speed or wider-temperature applications.

All SP3220 variants are active, RoHS compliant, and available in 16-TSSOP surface mount packages. Packaging options include Tube, Tape & Reel (TR), and Cut Tape (CT) & Digi-Reel® formats.

Frequently Asked Questions (FAQ)

Q: Can I use ICL3221CVZ-T as a direct replacement for ISL83220ECV-T? A: Yes. The ICL3221CVZ-T is a parametric equivalent with identical electrical specifications and package. Both are 1/1 full-duplex RS232 transceivers with 250kbps data rate, 300mV receiver hysteresis, and 16-TSSOP surface mount packaging. The ICL3221CVZ-T is active and RoHS3 compliant.

Q: What is the difference between SP3220EBCY-L and SP3220EBEY-L/TR? A: Both parts are functionally identical with 250kbps data rate and 300mV receiver hysteresis. The primary differences are packaging format (Tube vs. Tape & Reel) and operating temperature range. SP3220EBEY-L/TR supports -40°C–85°C, while SP3220EBCY-L supports 0°C–70°C. Select based on your thermal environment and procurement requirements.

Q: Can I use SP3220EUEY-L/TR if my application only requires 250kbps? A: Yes. SP3220EUEY-L/TR operates at 1Mbps, which exceeds the 250kbps requirement of the original ISL83220ECV-T. Higher data rate capability does not prevent operation at lower speeds. This part also supports extended temperature range (-40°C–85°C) and is RoHS compliant.

Q: Are all substitute parts available in the same 16-TSSOP package? A: Yes. All listed substitutes use the 16-TSSOP (0.173", 4.40mm Width) surface mount package, ensuring mechanical compatibility with existing PCB layouts.

Q: What is the significance of Moisture Sensitivity Level (MSL)? A: MSL indicates the maximum time a component can be exposed to moisture before soldering. MSL 1 (Unlimited) parts have no time restriction. MSL 3 (168 Hours) parts, such as ICL3221CVZ-T, must be soldered within 168 hours of package opening. Most SP3220 variants carry MSL 1 rating, offering greater handling flexibility.

Q: Why is the original ISL83220ECV-T marked as obsolete? A: Obsolete status indicates the manufacturer has discontinued production. The ICL3221CVZ-T and SP3220 series provide active alternatives with equivalent or superior specifications and modern compliance certifications.
