HIN241IBZ Equivalent & Substitute Parts

Part Overview

The HIN241IBZ is a 4/5 transceiver full RS232 interface IC manufactured by Renesas Electronics Corporation in 28-SOIC surface mount packaging. This part operates at 4.5V to 5.5V supply voltage with a data rate of 120Kbps and supports full-duplex RS232 communication with 500 mV receiver hysteresis. The HIN241IBZ is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new designs requiring RS232 transceiver functionality.

Substitute Part Grouping Explanation

Substitution for the HIN241IBZ is determined by strict equivalence across the following parameters: RS232 protocol, 4/5 driver/receiver configuration, full-duplex operation, 28-SOIC package, surface mount mounting type, and ROHS3 compliance. Substitute parts are grouped into two categories:

Direct Substitutes maintain all electrical parameters including 500 mV receiver hysteresis, 4.5V to 5.5V supply voltage range, and -40°C to 85°C operating temperature. These parts are pin-compatible and functionally identical.

Similar Substitutes maintain core RS232 transceiver functionality, 4/5 driver/receiver configuration, and 28-SOIC packaging but may differ in receiver hysteresis (650 mV), supply voltage range (4.75V to 5.25V), or operating temperature range (0°C to 70°C). These parts require design verification for specific application requirements.

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance): MAX241EWI+T is the primary direct substitute, offering identical electrical specifications including 500 mV receiver hysteresis, 4.5V to 5.5V supply voltage, and -40°C to 85°C operating temperature. This part is Active status with higher inventory availability (2070 Pcs) and is supplied in Tape & Reel packaging suitable for automated assembly.

MAX211EEWI+T provides an alternative direct substitute with matching electrical parameters and Active product status, available in Tape & Reel format with 3300 Pcs inventory.

For Extended Temperature Range Applications: Both MAX241EWI+T and MAX211EEWI+T support the full -40°C to 85°C operating temperature range of the original HIN241IBZ, making them suitable for industrial and automotive applications requiring extended temperature performance.

For Cost-Optimized Designs (Reduced Temperature Range): MAX211ECWI+T and MAX211CDWR offer Active product status with 500 mV receiver hysteresis and 4.5V to 5.5V supply voltage but operate within 0°C to 70°C temperature range. These parts are appropriate for commercial-grade applications not requiring extended temperature operation.

For Designs Tolerant of Parameter Variation: ADM241LARZ and ADM241LARZ-REEL provide Active status alternatives with 650 mV receiver hysteresis and 4.75V to 5.25V supply voltage range. These parts are suitable for applications where the tighter supply voltage tolerance and increased receiver hysteresis do not conflict with system requirements.

All substitute parts maintain ROHS3 compliance, 28-SOIC packaging, and RS232 4/5 transceiver functionality required for HIN241IBZ replacement.

Frequently Asked Questions (FAQ)

Q: Can MAX241EWI+T directly replace HIN241IBZ without design changes? A: Yes. MAX241EWI+T maintains identical electrical specifications including receiver hysteresis (500 mV), supply voltage range (4.5V to 5.5V), operating temperature (-40°C to 85°C), and 28-SOIC packaging. Pin configuration and functional behavior are equivalent.

Q: What is the difference between ADM241LARZ and ADM241LARZ-REEL? A: Both parts are electrically identical. The difference is packaging format: ADM241LARZ is supplied in Tube packaging for manual handling, while ADM241LARZ-REEL is supplied in Tape & Reel format for automated pick-and-place assembly. Select based on manufacturing process requirements.

Q: Why do some substitutes have 650 mV receiver hysteresis instead of 500 mV? A: ADM241 series parts from Analog Devices specify 650 mV receiver hysteresis as a design characteristic. This higher hysteresis value provides increased noise immunity but may affect signal detection timing in noise-sensitive applications. Verify compatibility with your specific RS232 signal levels and noise environment.

Q: Are MAX211 series parts suitable replacements for HIN241IBZ? A: MAX211 series parts maintain RS232 protocol, 4/5 transceiver configuration, 28-SOIC packaging, and 500 mV receiver hysteresis. However, most MAX211 variants operate within 0°C to 70°C temperature range, which is narrower than HIN241IBZ (-40°C to 85°C). MAX211EEWI+T is the exception, supporting the full -40°C to 85°C range. Verify temperature requirements before selection.

Q: What is the significance of product status (Active vs. Obsolete vs. Last Time Buy)? A: Active status indicates ongoing production and long-term availability. Last Time Buy indicates limited remaining production before discontinuation. Obsolete status means no further production. For new designs, select Active status parts to ensure long-term supply chain stability.

Q: Can I use parts with different supply voltage ranges interchangeably? A: No. HIN241IBZ operates at 4.5V to 5.5V. ADM241 series parts operate at 4.75V to 5.25V, which is a narrower range. If your system supplies voltage outside 4.75V to 5.25V (such as 4.5V to 4.74V or 5.26V to 5.5V), ADM241 parts will not function. Verify your actual supply voltage before selecting ADM241 alternatives.

Q: What packaging format should I choose for production? A: Tape & Reel (TR) packaging is standard for automated assembly and high-volume production. Tube packaging is suitable for manual assembly, prototyping, or low-volume applications. Both formats contain identical components; selection depends on manufacturing process.
