HIN211ECA-T RS232 Transceiver Equivalent & Substitute Parts
Part Overview
The HIN211ECA-T is a 4/5 full-duplex RS232 transceiver manufactured by Renesas Electronics Corporation in a 28-SSOP surface mount package. This component is classified as obsolete, which necessitates identification of equivalent and substitute parts for ongoing design support and production continuity. The part operates within a 4.5V to 5.5V supply range with a maximum data rate of 230 kbps and supports operating temperatures from 0°C to 70°C. Due to its obsolete status and RoHS non-compliant classification, active equivalent parts are required for new designs and legacy system maintenance.

Engineering Selection Recommendations
Parametric Equivalent (Direct Replacement):
The HIN211ECAZ-T from Renesas Electronics Corporation is the direct parametric equivalent to the HIN211ECA-T. This part maintains identical electrical specifications (230 kbps data rate, 500 mV receiver hysteresis, 0°C to 70°C operating range) and mechanical packaging (28-SSOP). The HIN211ECAZ-T holds Active product status and is ROHS3 compliant, making it suitable for new designs and legacy system replacements. The improved MSL rating (2 versus 3) provides enhanced moisture handling during manufacturing.
Primary Substitutes (Electrical Equivalence with Parameter Variations):
The MAX211CAI+ and MAX211CAI+T from Analog Devices/Maxim Integrated provide electrical equivalence with identical receiver hysteresis (500 mV) and operating temperature range (0°C to 70°C). These parts operate at 120 kbps data rate, which is acceptable for applications not requiring the full 230 kbps bandwidth of the original part. Both are Active, ROHS3 compliant, and available in 28-SSOP packaging. The MAX211CAI+T is supplied on tape and reel, while MAX211CAI+ is supplied in tube packaging.
Secondary Substitutes (Extended Operating Range):
The ADM211 series from Analog Devices (ADM211ARSZ, ADM211EARSZ, ADM211EARUZ variants) provides functional equivalence with extended operating temperature range (-40°C to 85°C) and superior moisture sensitivity (MSL 1). These parts operate at 120 kbps with 650 mV receiver hysteresis. The ADM211EARUZ and ADM211EARUZ-REEL7 variants are available in 28-TSSOP packaging (0.173" width), which is mechanically compatible with 28-SSOP footprints in most PCB designs. All ADM211 variants are Active and ROHS3 compliant.
Compliance and Availability Considerations:
All recommended substitute parts are ROHS3 compliant and hold Active product status, ensuring long-term availability and regulatory compliance for new designs. The original HIN211ECA-T is obsolete and RoHS non-compliant, making substitution necessary for production continuity.
Frequently Asked Questions (FAQ)
Q: Can the HIN211ECAZ-T directly replace the HIN211ECA-T without design modifications?
A: Yes. The HIN211ECAZ-T is a parametric equivalent with identical electrical specifications and 28-SSOP packaging. No design modifications are required. The part is pin-compatible and functionally equivalent.
Q: What is the difference between the MAX211CAI+ and MAX211CAI+T?
A: Both parts are electrically identical. The MAX211CAI+ is supplied in tube packaging, while the MAX211CAI+T is supplied on tape and reel. Selection depends on production volume and assembly line requirements.
Q: Can ADM211 series parts operate at the full 230 kbps data rate of the original HIN211ECA-T?
A: No. ADM211 series parts are specified for 120 kbps maximum data rate. They are suitable for applications operating at or below 120 kbps. For applications requiring 230 kbps operation, the HIN211ECAZ-T or MAX211 series parts are required.
Q: What is the difference between 28-SSOP and 28-TSSOP packaging?
A: Both are surface mount packages with identical pin counts and electrical compatibility. The 28-TSSOP (0.173" width) is narrower than the 28-SSOP (0.209" width). In most PCB designs, 28-TSSOP parts can be mounted on 28-SSOP footprints. Verify PCB layout compatibility before substitution.
Q: Are all substitute parts RoHS compliant?
A: Yes. All recommended substitute parts are ROHS3 compliant. The original HIN211ECA-T is RoHS non-compliant, making substitution necessary for regulatory compliance in new designs.
Q: What does MSL (Moisture Sensitivity Level) mean, and why does it vary?
A: MSL indicates the maximum time a component can be exposed to moisture at specified temperature and humidity conditions before soldering. MSL 1 (unlimited) provides the longest shelf life, while MSL 3 (168 hours) is more restrictive. Higher MSL ratings (lower numbers) are preferable for inventory management and manufacturing flexibility.
Q: Which substitute part offers the best extended temperature performance?
A: The ADM211 series parts operate from -40°C to 85°C, providing the widest temperature range. This makes them suitable for industrial and automotive applications requiring extended temperature operation beyond the original part's 0°C to 70°C range.
Q: Can I use ADM211EARUZ-REEL7 in place of HIN211ECA-T in a legacy design?
A: Yes, with PCB layout verification. The ADM211EARUZ-REEL7 is pin-compatible and functionally equivalent at data rates up to 120 kbps. The 28-TSSOP package is narrower than the original 28-SSOP, but is mechanically compatible with most 28-SSOP footprints. Confirm PCB pad spacing and clearances before production.
