SP3239EEA-L/TR Equivalent & Substitute Parts

Part Overview

The SP3239EEA-L/TR is an active RS232 interface transceiver manufactured by MaxLinear, Inc., configured as a full-duplex 5/3 transceiver (5 drivers, 3 receivers) in a 28-SSOP surface mount package. This component is classified as Active product status and is RoHS Compliant. Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part specifications, enabling direct replacement in applications where the original part becomes unavailable or inventory constraints require alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SP3239EEA-L/TR are identified based on strict alignment of the following critical parameters:

• Protocol: RS232
• Duplex: Full
• Receiver Hysteresis: 500 mV
• Data Rate: 250 kbps
• Voltage - Supply: 3V ~ 5.5V
• Operating Temperature: -40°C ~ 85°C
• Mounting Type: Surface Mount
• Package / Case: 28-SSOP (0.209", 5.30mm Width)

Two substitute parts meet these criteria with the following distinctions:

SP3238EEA-L/TR (MaxLinear, Inc.): Identical electrical specifications and package configuration. Differs only in base product number designation and packaging format availability (Cut Tape & Digi-Reel).

MAX3250EAI+T (Analog Devices Inc./Maxim Integrated): Meets all core electrical and physical parameters. Differs in driver/receiver configuration (2/2 versus 5/3) and moisture sensitivity level (MSL 1 versus MSL 2).

Parameter Comparison

Engineering Selection Recommendations

SP3238EEA-L/TR is the primary parametric equivalent for SP3239EEA-L/TR. Both parts are manufactured by MaxLinear, Inc., share identical electrical specifications, and are classified as Active products with RoHS compliance. Selection between these parts is determined by packaging format availability and inventory requirements rather than functional differences.

MAX3250EAI+T is a functional substitute with equivalent core electrical parameters and identical package configuration. This part is manufactured by Analog Devices Inc./Maxim Integrated and carries ROHS3 Compliant status with superior moisture sensitivity rating (MSL 1 versus MSL 2). The primary design consideration is the reduced driver/receiver count (2/2 versus 5/3), which limits this substitute to applications requiring only two driver and two receiver channels.

All three parts maintain Active product status and are suitable for new designs and production applications.

Frequently Asked Questions (FAQ)

Q: Can SP3238EEA-L/TR be used as a direct replacement for SP3239EEA-L/TR?

A: Yes. Both parts are manufactured by MaxLinear, Inc., with identical electrical specifications, driver/receiver configuration (5/3), and 28-SSOP package dimensions. Substitution is valid for all applications where the original part is specified.

Q: What is the primary difference between SP3239EEA-L/TR and MAX3250EAI+T?

A: The MAX3250EAI+T has a reduced driver/receiver configuration (2/2 versus 5/3). This part is suitable only for applications requiring two driver channels and two receiver channels. All other electrical parameters, including supply voltage, data rate, operating temperature, and package configuration, are equivalent.

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. All three parts use the 28-SSOP package with identical dimensions (0.209", 5.30mm Width), ensuring footprint compatibility on the same printed circuit board.

Q: What is the difference in moisture sensitivity between these parts?

A: SP3239EEA-L/TR and SP3238EEA-L/TR are rated MSL 2 (1 Year), while MAX3250EAI+T is rated MSL 1 (Unlimited). MSL 1 indicates superior moisture resistance and longer shelf life without baking requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. SP3239EEA-L/TR is RoHS Compliant. SP3238EEA-L/TR and MAX3250EAI+T are both ROHS3 Compliant, meeting current regulatory requirements.

Q: Can MAX3250EAI+T replace SP3239EEA-L/TR in a design requiring five drivers and three receivers?

A: No. The MAX3250EAI+T provides only two drivers and two receivers. This part is suitable only for applications with reduced channel requirements. For designs requiring the full 5/3 configuration, use SP3238EEA-L/TR.
