SP211ECA-L RS232 Transceiver Equivalent & Substitute Parts

Part Overview

The SP211ECA-L is a full-duplex RS232 transceiver manufactured by MaxLinear, Inc., configured with 4 drivers and 5 receivers in a 28-SSOP surface mount package. This component is classified as obsolete, making equivalent substitutes necessary for ongoing system support and new design implementations. The part operates across a 4.5V to 5.5V supply range with a 120 kbps data rate and -40°C to 85°C temperature range.

Substitute Part Grouping Explanation

Substitution eligibility for the SP211ECA-L is determined by the following critical parameters:

Protocol: RS232 (mandatory match)
Configuration: 4/5 drivers/receivers (mandatory match)
Package: 28-SSOP surface mount (mandatory match)
Supply Voltage Range: 4.5V ~ 5.5V or compatible subset
Data Rate: 120 kbps minimum capability
Operating Temperature: Must support -40°C ~ 85°C or equivalent industrial range
Receiver Hysteresis: 500 mV or 650 mV acceptable
Duplex: Full duplex (mandatory match)

Substitute parts are grouped into two categories: direct equivalents from Texas Instruments and Renesas Electronics, and manufacturer-recommended alternatives from Analog Devices Inc. All substitutes maintain identical electrical functionality and package specifications while offering active product status and improved availability.

Engineering Selection Recommendations

For applications requiring full compatibility with the SP211ECA-L operating range of -40°C to 85°C, ADM211ARSZ and ADM211EARSZ from Analog Devices Inc. are the primary substitutes. Both parts maintain identical supply voltage specifications, temperature range, and package configuration. These components carry active product status and ROHS3 compliance certification, ensuring long-term availability and regulatory alignment.

ADM241LARSZ and ADM241LJRSZ offer narrower supply voltage windows (4.75V ~ 5.25V) compared to the original part. ADM241LARSZ maintains the full industrial temperature range (-40°C ~ 85°C), while ADM241LJRSZ is limited to 0°C ~ 70°C. Both are active products with ROHS3 compliance.

TRS211CDB from Texas Instruments is an obsolete direct equivalent with matching electrical parameters but restricted to 0°C ~ 70°C operation. This part is suitable only for applications not requiring extended low-temperature performance.

HIN211ECAZ from Renesas Electronics Corporation is an active product with enhanced data rate capability (230 kbps) but operates within 0°C ~ 70°C temperature limits. This part is appropriate for commercial-grade applications not requiring military or extended industrial temperature ranges.

Frequently Asked Questions (FAQ)

Q: Can ADM241LARSZ replace SP211ECA-L in all applications?

A: ADM241LARSZ is functionally compatible but operates within a narrower supply voltage range (4.75V ~ 5.25V versus 4.5V ~ 5.5V). Applications requiring operation at 4.5V or 5.5V must use ADM211ARSZ or ADM211EARSZ instead.

Q: What is the difference between ADM211ARSZ and ADM211EARSZ?

A: Both parts are electrically identical with matching temperature ranges (-40°C ~ 85°C) and supply specifications (4.5V ~ 5.5V). The primary difference is packaging: ADM211ARSZ is supplied in tube packaging, while ADM211EARSZ is supplied in tube format. Consult packaging specifications for your procurement requirements.

Q: Is HIN211ECAZ suitable for industrial temperature applications?

A: HIN211ECAZ operates within 0°C ~ 70°C limits, making it unsuitable for applications requiring -40°C operation. For extended temperature range requirements, use ADM211ARSZ, ADM211EARSZ, or ADM241LARSZ.

Q: Why does HIN211ECAZ have a higher data rate specification?

A: HIN211ECAZ supports 230 kbps data rate compared to 120 kbps for SP211ECA-L. This enhanced capability does not affect substitution eligibility, as the part maintains full backward compatibility with lower data rate applications.

Q: Are all substitute parts ROHS3 compliant?

A: All active substitute parts listed (ADM211ARSZ, ADM211EARSZ, ADM241LARSZ, ADM241LJRSZ, and HIN211ECAZ) carry ROHS3 compliance certification. TRS211CDB, though obsolete, also maintains ROHS3 compliance.

Q: What packaging options are available for the recommended substitutes?

A: Analog Devices ADM211 and ADM241 series are available in tube and tape & reel formats. Verify specific packaging availability (ADM211ARSZ-REEL, ADM241LARSZ-REEL, ADM211EARSZ-REEL, ADM241LJRSZ-REEL) through your component supplier for production volume requirements.
