Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SP211ECT-L is determined by the following critical parameters:

Primary Compatibility Criteria:

• Protocol: RS232
• Number of Drivers/Receivers: 4/5
• Duplex: Full
• Package / Case: 28-SOIC (0.295", 7.50mm Width)
• Mounting Type: Surface Mount

Secondary Compatibility Criteria:

• Voltage - Supply: 4.5V ~ 5.5V
• Operating Temperature: 0°C ~ 70°C
• Data Rate: 230kbps
• Receiver Hysteresis: 500 mV

Parts meeting all primary criteria and secondary criteria are classified as parametric equivalents. Parts meeting primary criteria with variations in secondary parameters are classified as functional alternatives requiring application-level verification.

Engineering Selection Recommendations

HIN211ECBZ (Parametric Equivalent - Preferred Selection)

The HIN211ECBZ from Renesas Electronics Corporation is a parametric equivalent meeting all primary and secondary compatibility criteria. It maintains identical voltage supply range (4.5V ~ 5.5V), data rate (230kbps), and receiver hysteresis (500 mV) specifications. The part is currently in active production status with ROHS3 compliance certification. Inventory availability is confirmed at 3,516 pieces. This part provides direct functional replacement with no application-level modifications required.

ADM561JRZ (MFR Recommended - Functional Alternative)

The ADM561JRZ from Analog Devices Inc. meets primary compatibility criteria but operates at a reduced voltage supply range (3V ~ 3.6V) and lower data rate (116Kbps) with reduced receiver hysteresis (300 mV). This part is suitable only for applications where the lower voltage supply and reduced data rate specifications are acceptable. The part is in active production status with ROHS3 compliance and superior moisture sensitivity rating (MSL 1). Inventory availability is confirmed at 36,300 pieces.

Frequently Asked Questions (FAQ)

Q: Can the HIN211ECBZ directly replace the SP211ECT-L without PCB modifications?

A: Yes. The HIN211ECBZ is a parametric equivalent with identical package dimensions (28-SOIC), mounting type (surface mount), and all critical electrical specifications. No PCB layout changes are required.

Q: What are the key differences between the HIN211ECBZ and ADM561JRZ?

A: The HIN211ECBZ maintains the original SP211ECT-L voltage supply range (4.5V ~ 5.5V) and data rate (230kbps). The ADM561JRZ operates at a lower voltage range (3V ~ 3.6V) and reduced data rate (116Kbps). Selection depends on your application's power supply and communication speed requirements.

Q: Is the ADM561JRZ suitable for 5V applications?

A: No. The ADM561JRZ maximum supply voltage is 3.6V, making it incompatible with standard 5V systems. The HIN211ECBZ is the appropriate choice for 4.5V ~ 5.5V applications.

Q: What is the significance of the receiver hysteresis difference between parts?

A: Receiver hysteresis affects noise immunity and signal transition characteristics. The SP211ECT-L and HIN211ECBZ both specify 500 mV hysteresis, providing identical noise margin performance. The ADM561JRZ specifies 300 mV, resulting in reduced noise immunity.

Q: Are all three parts RoHS compliant?

A: Yes. The SP211ECT-L is RoHS Compliant. Both the HIN211ECBZ and ADM561JRZ are ROHS3 Compliant, meeting current environmental standards.

Q: What does MSL 3 (168 Hours) mean compared to MSL 1 (Unlimited)?

A: MSL indicates moisture sensitivity level and floor life. MSL 3 (168 Hours) requires baking before reflow if the part has been exposed to moisture for more than 168 hours. MSL 1 (Unlimited) has no floor life restriction. For standard manufacturing processes, both ratings are acceptable.
