SP211EHCA-L Equivalent & Substitute Parts

Part Overview

The SP211EHCA-L is a 4/5 Transceiver Full RS232 interface IC manufactured by MaxLinear, Inc., housed in a 28-SSOP package. This component is classified as obsolete, indicating that direct procurement from the original manufacturer is no longer available. Identifying qualified substitute parts is essential for system redesign, legacy product support, and ensuring continued supply chain viability for applications requiring RS232 transceiver functionality.

Substitute Part Grouping Explanation

Substitution of the SP211EHCA-L is determined by strict alignment of the following electrical and mechanical parameters:

Protocol: RS232 (mandatory match)
Number of Drivers/Receivers: 4/5 (mandatory match)
Duplex: Full (mandatory match)
Voltage - Supply: 4.5V ~ 5.5V (compatible range required)
Mounting Type: Surface Mount (mandatory match)
Package / Case: 28-SSOP or 28-TSSOP (pin-compatible packages)

Substitute parts from Analog Devices Inc. meet these criteria across multiple product variants (ADM211 and ADM241 series). All substitute candidates maintain RS232 protocol compliance, identical driver/receiver configuration, and compatible supply voltage ranges. Package variants include both 28-SSOP and 28-TSSOP options, which are mechanically compatible for surface mount applications.

Engineering Selection Recommendations

All substitute parts listed are manufactured by Analog Devices Inc. and carry Active product status, ensuring long-term availability and supply chain stability. The ADM211 and ADM241 series are ROHS3 compliant with MSL rating of 1 (Unlimited), providing superior moisture handling compared to the obsolete SP211EHCA-L.

For applications requiring the original operating temperature range of 0°C ~ 70°C, ADM241LJRSZ is the direct functional equivalent. This variant maintains identical thermal specifications while offering improved compliance certifications and unlimited moisture sensitivity rating.

For applications capable of operating within the extended temperature range of -40°C ~ 85°C, ADM211ARSZ, ADM211EARSZ, ADM211EARUZ, and ADM241LARSZ provide additional thermal margin and are available in higher inventory quantities.

Package selection between 28-SSOP and 28-TSSOP variants depends on PCB layout constraints. Both packages are mechanically compatible for surface mount assembly. The 28-TSSOP variant (ADM211EARUZ series) offers a narrower package width of 4.40mm compared to 28-SSOP at 5.30mm.

Frequently Asked Questions (FAQ)

Q: Can ADM211 and ADM241 series parts be used interchangeably with SP211EHCA-L?

A: Yes, within the constraints of electrical and mechanical compatibility. Both series maintain RS232 protocol, 4/5 driver/receiver configuration, full duplex operation, and compatible supply voltage ranges. The primary selection criterion is operating temperature range and package type.

Q: What is the significance of the receiver hysteresis difference (500 mV vs. 650 mV)?

A: Receiver hysteresis affects input signal discrimination. The SP211EHCA-L specifies 500 mV hysteresis, while all Analog Devices substitutes specify 650 mV. This difference is within RS232 specification tolerances and does not prevent functional substitution in standard applications.

Q: Why is the data rate specification different (480 Kbps vs. 120 Kbps)?

A: The SP211EHCA-L is rated for 480 Kbps maximum data rate, while substitute parts are rated for 120 Kbps. For applications requiring data rates exceeding 120 Kbps, substitute parts may not be suitable. Verify application data rate requirements before selection.

Q: What is the difference between 28-SSOP and 28-TSSOP packages?

A: Both are 28-pin surface mount packages with identical pin pitch and electrical compatibility. The primary difference is package width: 28-SSOP is 5.30mm wide, while 28-TSSOP is 4.40mm wide. PCB layout and assembly equipment capabilities determine which package is appropriate.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All Analog Devices substitute parts (ADM211 and ADM241 series) are ROHS3 compliant. The original SP211EHCA-L does not specify RoHS compliance status.

Q: What is the MSL rating and why does it matter?

A: Moisture Sensitivity Level (MSL) indicates how long a component can be stored in standard conditions before moisture absorption affects reliability. The SP211EHCA-L has MSL 2 (1 Year), while all substitutes have MSL 1 (Unlimited), providing superior shelf life and handling flexibility.

Q: Which substitute part is the closest match to SP211EHCA-L?

A: ADM241LJRSZ is the closest functional match, maintaining the identical operating temperature range of 0°C ~ 70°C while providing active product status, ROHS3 compliance, and unlimited MSL rating.
