SP3245ECA-L Equivalent & Substitute Parts

Part Overview

The SP3245ECA-L is a full-duplex RS232 transceiver IC manufactured by MaxLinear, Inc., configured with 3 drivers and 5 receivers in a 28-SSOP surface mount package. This device operates across a 3V to 5.5V supply range with a 1 Mbps data rate and is designed for serial communication interface applications. The part is currently classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SP3245ECA-L is determined by strict equivalence across the following critical parameters:

• Protocol: RS232
• Number of Drivers/Receivers: 3/5 configuration
• Duplex Mode: Full
• Data Rate: 1 Mbps
• Voltage Supply Range: 3V ~ 5.5V
• Operating Temperature Range: 0°C ~ 70°C
• Package Type: 28-SSOP with identical physical dimensions (0.209", 5.30mm Width)
• Mounting Type: Surface Mount

All substitute parts listed maintain these core electrical and mechanical specifications. Variations in receiver hysteresis (200 mV vs. 500 mV), moisture sensitivity level, and product status are noted but do not prevent functional substitution within the defined parameter set.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are functionally equivalent to the SP3245ECA-L within the defined electrical and mechanical parameter set. Selection among substitutes should be based on the following criteria:

Product Status: All substitute parts carry Active product status, ensuring long-term availability and manufacturing support compared to the obsolete SP3245ECA-L.

Compliance & Certifications: All substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Packaging Format: Choose between Tube packaging (ICL3245CAZ, ICL3245ECAZ, MAX3245CAI+, MAX3245ECAI+) for smaller quantities or Tape & Reel (TR) packaging (ICL3245CAZ-T, MAX3245CAI+T, MAX3245ECAI+T) for high-volume production applications.

Manufacturer Selection: Renesas Electronics Corporation (ICL3245 series) and Analog Devices Inc./Maxim Integrated (MAX3245 series) both provide qualified alternatives with established supply chains and technical support.

Moisture Sensitivity: MAX3245 variants offer MSL 1 (Unlimited) compared to ICL3245 variants at MSL 2 (1 Year), providing superior moisture tolerance for extended storage and harsh environmental conditions.

Frequently Asked Questions (FAQ)

Q: Can the SP3245ECA-L be directly replaced with any of the listed substitutes?

A: Yes. All listed parts maintain identical electrical specifications (RS232 protocol, 3/5 driver/receiver configuration, full-duplex operation, 1 Mbps data rate, 3V–5.5V supply, 0°C–70°C operating range) and identical physical packaging (28-SSOP, 0.209" × 5.30mm). Direct pin-for-pin substitution is supported.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging is suitable for manual assembly and smaller production runs. Tape & Reel (TR) packaging is designed for automated pick-and-place assembly equipment and high-volume manufacturing. Both formats contain identical components; packaging selection depends on assembly methodology.

Q: Why do some substitutes have different receiver hysteresis values?

A: The SP3245ECA-L specifies 200 mV receiver hysteresis, while most substitutes specify 500 mV. Both values fall within acceptable RS232 interface specifications and do not prevent functional substitution. The higher hysteresis in substitute parts provides improved noise immunity in electrically noisy environments.

Q: What is the significance of MSL (Moisture Sensitivity Level) differences?

A: MSL 1 (Unlimited) indicates the component can be stored indefinitely without moisture baking requirements. MSL 2 (1 Year) requires moisture baking if storage exceeds one year or if the component is exposed to high humidity. MAX3245 variants with MSL 1 are preferred for long-term inventory management.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental regulations for electronic components in the European Union and other regulated markets.
