SP3224ECA-L/TR Equivalent & Substitute Parts

Part Overview

The SP3224ECA-L/TR is a 2/2 full-duplex RS232 transceiver manufactured by MaxLinear, Inc., housed in a 20-SSOP surface mount package. This component operates across a 3V to 5.5V supply range with a 250kbps data rate and 500mV receiver hysteresis. The part is currently classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SP3224ECA-L/TR is determined by strict alignment of the following parameters:

• Protocol: RS232
• Number of Drivers/Receivers: 2/2
• Duplex: Full
• Receiver Hysteresis: 500 mV
• Data Rate: 250kbps
• Voltage - Supply: 3V ~ 5.5V
• Mounting Type: Surface Mount
• Package / Case: 20-SSOP (0.209", 5.30mm Width)

Substitute parts are categorized into two groups:

MFR Recommended Substitutes — Parts actively recommended by manufacturers as direct replacements, with active product status and full compliance certifications.

Parametric Equivalents — Parts matching all critical electrical and mechanical parameters, including operating temperature ranges and packaging formats, suitable for applications where the original specification can be met.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (MFR Recommended, Active Status)

ICL3224EIAZ and ICL3224EIAZ-T from Renesas Electronics are manufacturer-recommended substitutes with active product status and ROHS3 compliance. These parts extend the operating temperature range to -40°C ~ 85°C, providing enhanced thermal performance over the original SP3224ECA-L/TR specification. Both are available in standard tube and tape & reel packaging formats.

MAX3224CAP+, MAX3224ECAP+, MAX3224CAP+T, and MAX3224ECAP+T from Analog Devices Inc./Maxim Integrated maintain the original 0°C ~ 70°C operating temperature range and are actively produced with ROHS3 compliance. These parts feature improved moisture sensitivity levels (MSL 1, Unlimited) compared to the original part (MSL 2, 1 Year), reducing handling and storage constraints.

Secondary Substitutes (Parametric Equivalents, Active Status)

ICL3222ECAZ-T and ICL3225ECAZ-T from Renesas Electronics match all critical electrical parameters and maintain the 0°C ~ 70°C operating temperature specification. Both are ROHS3 compliant and actively produced. ICL3222ECAZ-T carries MSL 3 (168 Hours), while ICL3225ECAZ-T carries MSL 2 (1 Year).

Obsolete Alternatives

MAX3223CDBR from Texas Instruments is classified as obsolete and should not be selected for new designs, despite meeting parametric requirements.

Frequently Asked Questions (FAQ)

Q: Can I use ICL3224EIAZ as a direct replacement for SP3224ECA-L/TR?

A: Yes. ICL3224EIAZ meets all critical electrical parameters: RS232 protocol, 2/2 drivers/receivers, full duplex, 500mV receiver hysteresis, 250kbps data rate, 3V ~ 5.5V supply voltage, and 20-SSOP package. The extended operating temperature range (-40°C ~ 85°C) provides additional thermal margin. Packaging format differs (tube vs. original specification); select ICL3224EIAZ-T for tape & reel format compatibility.

Q: What is the difference between MAX3224CAP+ and MAX3224ECAP+?

A: Both parts are electrically and mechanically identical, meeting all SP3224ECA-L/TR substitution criteria. The difference lies in packaging format: MAX3224CAP+ is supplied in tube packaging, while MAX3224ECAP+ is supplied in cut tape & digi-reel format. Select based on your assembly process requirements.

Q: Why do some substitutes have different operating temperature ranges?

A: Operating temperature range is a design specification that does not affect substitution eligibility for the SP3224ECA-L/TR. The original part operates 0°C ~ 70°C. Substitutes with extended ranges (such as ICL3224EIAZ at -40°C ~ 85°C) provide additional thermal performance margin but are functionally equivalent within the original temperature specification.

Q: What does MSL (Moisture Sensitivity Level) mean for component selection?

A: MSL indicates the maximum time a component can be exposed to ambient conditions (typically 30°C, 85% relative humidity) before soldering. The original SP3224ECA-L/TR carries MSL 2 (1 Year). Substitutes with MSL 1 (Unlimited) offer relaxed storage and handling requirements. Substitutes with MSL 3 (168 Hours) require more stringent moisture control. Select based on your supply chain and manufacturing environment.

Q: Are all listed substitutes ROHS3 compliant?

A: All active substitute parts listed carry ROHS3 compliance certification. The original SP3224ECA-L/TR does not specify RoHS status. MAX3223CDBR, though ROHS3 compliant, is obsolete and unsuitable for new designs.

Q: Can I mix packaging formats in production?

A: Packaging format (tube, tape & reel, cut tape) affects assembly process compatibility but not electrical or mechanical function. Select packaging format based on your pick-and-place equipment and assembly workflow. All listed substitutes in the same base part number (MAX3224, ICL3224, ICL3225) are electrically identical.
