HIN241CBZ RS232 Transceiver Equivalent & Substitute Parts

Part Overview

The HIN241CBZ is a 4/5 transceiver full-duplex RS232 interface IC manufactured by Renesas Electronics Corporation in 28-SOIC surface mount packaging. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations. The HIN241CBZ operates within a 4.5V to 5.5V supply voltage range with a 120 kbps data rate and 500 mV receiver hysteresis, suitable for legacy serial communication applications requiring full RS232 protocol compliance.

Substitute Part Grouping Explanation

Substitution of the HIN241CBZ is determined by strict adherence to the following critical parameters:

Core Compatibility Parameters:

Protocol: RS232 full-duplex transceiver
Number of Drivers/Receivers: 4/5 configuration
Package / Case: 28-SOIC (0.295", 7.50mm Width)
Mounting Type: Surface Mount
Data Rate: 120 kbps minimum
Voltage - Supply: 4.5V ~ 5.5V (or compatible range)
Receiver Hysteresis: 500 mV (or compatible)

Substitute parts are grouped into two categories:

Direct Substitutes (Identical Electrical Parameters): Parts that match all core electrical specifications of the HIN241CBZ, including 500 mV receiver hysteresis and 4.5V ~ 5.5V supply voltage range.

Similar Substitutes (Compatible with Design Considerations): Parts that maintain 4/5 transceiver RS232 functionality in 28-SOIC packaging but may differ in receiver hysteresis (650 mV), supply voltage range (4.75V ~ 5.25V), or operating temperature range. These require design verification to confirm compatibility with the target application.

Engineering Selection Recommendations

Direct Substitutes (Recommended for Pin-Compatible Replacement):

MAX241CWI+T, MAX211CDWR, MAX211CWI+T, MAX211ECWI+T, MAX211EEWI+, and MAX211EEWI+T maintain identical electrical specifications to the HIN241CBZ across receiver hysteresis (500 mV) and supply voltage range (4.5V ~ 5.5V). All substitute parts are active products with ROHS3 compliance and REACH unaffected status. These parts are suitable for direct substitution in applications operating within the 0°C to 70°C temperature range. Parts with extended temperature range (-40°C ~ 85°C) provide additional operational margin for demanding environments.

Similar Substitutes (Conditional Compatibility):

ADM241LARZ, ADM241LARZ-REEL, ADM241LJRZ, and ADM241LJRZ-REEL feature 650 mV receiver hysteresis and 4.75V ~ 5.25V supply voltage range, representing tighter specifications than the HIN241CBZ. These parts are active products with superior moisture sensitivity levels (MSL 1 Unlimited versus MSL 3 168 Hours). Selection of these parts requires confirmation that the application design accommodates the higher receiver hysteresis threshold and narrower supply voltage tolerance.

All substitute parts are available in both tube and tape & reel packaging formats. Packaging selection depends on manufacturing process requirements and inventory management protocols.

Frequently Asked Questions (FAQ)

Q: Can MAX241CWI+T directly replace HIN241CBZ in existing designs?

A: Yes. MAX241CWI+T matches all core electrical parameters of HIN241CBZ: 4/5 transceiver configuration, RS232 protocol, 500 mV receiver hysteresis, 4.5V ~ 5.5V supply voltage, 120 kbps data rate, and 28-SOIC packaging. Both operate within 0°C to 70°C temperature range. The primary difference is packaging format (tape & reel versus tube) and improved moisture sensitivity level.

Q: What is the difference between ADM241LJRZ and ADM241LARZ?

A: Both parts are Analog Devices ADM241 series transceivers in 28-SOIC packaging with identical electrical specifications. The primary difference is operating temperature range: ADM241LJRZ operates 0°C ~ 70°C (matching HIN241CBZ), while ADM241LARZ operates -40°C ~ 85°C. Both feature 650 mV receiver hysteresis and 4.75V ~ 5.25V supply voltage range. REEL variants indicate tape & reel packaging; non-REEL variants indicate tube packaging.

Q: Are ADM241 series parts compatible with HIN241CBZ?

A: ADM241 series parts maintain 4/5 transceiver RS232 functionality in 28-SOIC packaging but feature 650 mV receiver hysteresis versus 500 mV for HIN241CBZ, and 4.75V ~ 5.25V supply voltage versus 4.5V ~ 5.5V. These differences require design verification. Applications with supply voltage regulation within 4.75V ~ 5.25V and receiver threshold tolerance for 650 mV hysteresis can use ADM241 parts.

Q: What packaging options are available for substitute parts?

A: Substitute parts are available in tube and tape & reel (TR) packaging. Tube packaging is standard for lower-volume applications and manual assembly. Tape & reel packaging is standard for automated pick-and-place manufacturing. Selection depends on production volume and assembly process requirements.

Q: Do all substitute parts meet RoHS and REACH compliance?

A: Yes. All substitute parts listed are ROHS3 compliant and REACH unaffected, matching the compliance status of HIN241CBZ.

Q: What is the significance of MSL (Moisture Sensitivity Level) differences?

A: HIN241CBZ carries MSL 3 (168 Hours), requiring controlled storage and handling within 168 hours of package opening. All substitute parts carry MSL 1 (Unlimited), eliminating moisture sensitivity constraints and reducing storage and handling complexity. This represents an improvement in supply chain flexibility.
