HIN202CB RS232 Transceiver Equivalent & Substitute Parts

Part Overview

The HIN202CB is a 2/2 full-duplex RS232 transceiver manufactured by Renesas Electronics Corporation in a 16-SOIC surface mount package. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The HIN202CB operates within a 4.5V to 5.5V supply range with a 120 kbps data rate and 500 mV receiver hysteresis, serving as a standard interface component for RS232 serial communication applications.

Substitute Part Grouping Explanation

Substitution of the HIN202CB is determined by strict equivalence across the following critical parameters:

Protocol: RS232
Number of Drivers/Receivers: 2/2
Duplex: Full
Voltage Supply Range: 4.5V ~ 5.5V
Package / Case: 16-SOIC (0.295", 7.50mm Width)
Mounting Type: Surface Mount

Substitute parts are grouped into three categories based on their relationship to the main part:

Parametric Equivalents maintain identical electrical specifications and differ only in product status (active vs. obsolete) or packaging format (tube vs. reel). These parts are direct functional replacements.

Direct Manufacturer Equivalents are from alternative manufacturers (Analog Devices Inc., Maxim Integrated) and meet all core electrical and mechanical requirements. Minor variations in receiver hysteresis (500 mV vs. 650 mV) or data rate do not affect functional compatibility within standard RS232 applications.

Similar Parts share the same protocol, driver/receiver configuration, and package but may have variations in operating temperature range, receiver hysteresis, or data rate specifications. These parts are suitable for applications where the specified parameter variations are acceptable.

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): HIN202CBZ is the primary choice as a parametric equivalent. It maintains all electrical specifications of the HIN202CB while offering active product status and ROHS3 compliance. This part is suitable for designs requiring no specification changes.

For Active Production with RoHS Compliance: MAX202CWE+T or MAX202EWE+ provide equivalent functionality with ROHS3 compliance. MAX202CWE+T maintains the original operating temperature range (0°C ~ 70°C), while MAX202EWE+ extends the operating range to -40°C ~ 85°C for applications requiring broader temperature support.

For Extended Temperature Range Applications: MAX202EWE+ or ADM202EARWZ offer operating temperatures from -40°C to 85°C, suitable for industrial or automotive environments where the original 0°C ~ 70°C range is insufficient.

For Higher Data Rate Requirements: ADM202EARWZ and ADM202EARWZ-REEL support 230 kbps data rates, double the HIN202CB specification, while maintaining full RS232 2/2 transceiver functionality.

For Packaging Flexibility: ADM232LJRZ-REEL, ADM202EARWZ-REEL, and ADM202JRWZ-REEL are available in tape and reel format for high-volume automated assembly, while tube packaging options are available for lower-volume applications.

Frequently Asked Questions (FAQ)

Q: Can HIN202CBZ be used as a direct replacement for HIN202CB? A: Yes. HIN202CBZ is a parametric equivalent with identical electrical specifications (500 mV receiver hysteresis, 120 kbps data rate, 4.5V ~ 5.5V supply). The primary differences are product status (active vs. obsolete) and RoHS compliance (ROHS3 vs. non-compliant). No design changes are required.

Q: What is the difference between 500 mV and 650 mV receiver hysteresis? A: Receiver hysteresis affects the input threshold switching behavior. The 500 mV specification in HIN202CB and MAX202 parts provides tighter input thresholds compared to the 650 mV specification in ADM232 and ADM202 parts. Both values are within RS232 standard tolerances and are functionally compatible for standard serial communication applications.

Q: Are ADM202EARWZ and ADM202JRWZ interchangeable? A: Both are ADM202 variants with identical supply voltage and package specifications. ADM202EARWZ operates at -40°C ~ 85°C with 230 kbps data rate and 650 mV hysteresis, while ADM202JRWZ operates at 0°C ~ 70°C with 400 mV hysteresis. Selection depends on required operating temperature and data rate specifications.

Q: What packaging options are available? A: Substitute parts are available in three packaging formats: Tube (standard for lower volumes), Cut Tape & Digi-Reel (for automated assembly), and Tape & Reel (for high-volume production). All maintain the 16-SOIC (0.295", 7.50mm Width) package footprint.

Q: Is RoHS compliance required for my application? A: The original HIN202CB is RoHS non-compliant. All active substitute parts listed (HIN202CBZ, HIN232CBZ, ADM232LJRZ, MAX202 series, ADM202 series) are ROHS3 compliant. If RoHS compliance is a design requirement, any of these active parts are suitable replacements.

Q: Can I use MAX202EWE+ in place of HIN202CB? A: Yes. MAX202EWE+ meets all core electrical requirements (2/2 RS232 transceiver, 500 mV hysteresis, 120 kbps data rate, 4.5V ~ 5.5V supply, 16-SOIC package). The extended operating temperature range (-40°C ~ 85°C vs. 0°C ~ 70°C) is a superset of the original specification and does not affect compatibility.
