Substitute Part Grouping Explanation
Substitution for the HIN232ACB is determined by strict equivalence across the following critical parameters:
- Protocol: RS232
- Number of Drivers/Receivers: 2/2 configuration
- Duplex Mode: Full duplex operation
- Voltage Supply Range: 4.5V ~ 5.5V
- Package Type: 16-SOIC surface mount
- Data Rate Capability: Minimum 230 kbps
Substitute parts are categorized into two groups:
Parametric Equivalents maintain identical electrical specifications and package dimensions, differing only in product status (active vs. obsolete) and compliance certifications. These parts are direct functional replacements.
Similar Parts share the same protocol, driver/receiver configuration, and supply voltage but may differ in data rate, operating temperature range, receiver hysteresis, package width, or compliance status. These parts require design verification for specific application requirements.

Engineering Selection Recommendations
Parametric Equivalents (Direct Replacements):
HIN202ECBZ and HIN232ECBZ are parametric equivalents manufactured by Renesas Electronics Corporation. Both parts maintain identical electrical specifications to the HIN232ACB, including 230 kbps data rate, 2/2 driver/receiver configuration, and 16-SOIC (7.50mm) package. Both are active products with ROHS3 compliance, providing regulatory advantage over the obsolete HIN232ACB. These parts are suitable for direct substitution without design modification.
Similar Parts (Conditional Substitution):
Analog Devices ADM232 series parts (ADM232AARNZ-REEL, ADM232AARNZ-REEL7, ADM232AARWZ, ADM232AARWZ-REEL, ADM232LARZ, ADM232LARZ-REEL, ADM232LJRZ) are active products with ROHS3 compliance and extended operating temperature ranges (-40°C to 85°C). These parts maintain the RS232 protocol, 2/2 configuration, and 4.5V to 5.5V supply voltage. However, data rates range from 120 kbps to 200 kbps, which is below the HIN232ACB specification of 230 kbps. Package width variations (3.90mm vs. 7.50mm) may require PCB layout adjustment. Selection depends on application data rate requirements and thermal operating conditions.
Frequently Asked Questions (FAQ)
Q: Can HIN202ECBZ or HIN232ECBZ be used as direct replacements for HIN232ACB?
A: Yes. Both parts are parametric equivalents with identical electrical specifications (230 kbps data rate, 2/2 drivers/receivers, 4.5V to 5.5V supply, 16-SOIC 7.50mm package). Both are active products with ROHS3 compliance, eliminating the regulatory disadvantage of the obsolete HIN232ACB.
Q: What is the key difference between parametric equivalents and similar parts?
A: Parametric equivalents maintain all critical electrical and mechanical specifications. Similar parts share the same protocol and core configuration but differ in data rate, operating temperature range, or package dimensions. Similar parts require application-level verification before substitution.
Q: Can ADM232 series parts replace HIN232ACB in all applications?
A: ADM232 series parts are suitable only if the application data rate requirement does not exceed 200 kbps (ADM232AARNZ-REEL variants) or 120 kbps (ADM232LARZ and ADM232LJRZ variants). The HIN232ACB supports 230 kbps. Package width differences (3.90mm vs. 7.50mm) may require PCB layout modification.
Q: What is the significance of the operating temperature range difference?
A: The HIN232ACB operates from 0°C to 70°C. Most ADM232 variants operate from -40°C to 85°C, providing extended low-temperature and high-temperature capability. ADM232LJRZ matches the HIN232ACB temperature range (0°C to 70°C). Temperature range selection depends on the target application environment.
Q: Are all substitute parts RoHS compliant?
A: The HIN232ACB is RoHS non-compliant. All parametric equivalents (HIN202ECBZ, HIN232ECBZ) and similar parts (ADM232 series) are ROHS3 compliant, meeting current regulatory requirements for new designs and production.
Q: What packaging options are available for substitute parts?
A: Parametric equivalents are supplied in Tube packaging. ADM232 series parts are available in Cut Tape (CT) & Digi-Reel or Tube packaging. Packaging selection affects handling, storage, and assembly processes but does not impact electrical performance.
