HIN202IB RS232 Transceiver Equivalent & Substitute Parts

Part Overview

The HIN202IB is a 2/2 full-duplex RS232 transceiver manufactured by Renesas Electronics Corporation in a 16-SOIC surface mount package. This interface IC operates across the 4.5V to 5.5V supply range with a 120 kbps data rate and -40°C to 85°C operating temperature range. The HIN202IB is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations. Substitute parts must maintain compatibility across electrical specifications, mechanical packaging, and functional performance parameters.

Substitute Part Grouping Explanation

Substitution eligibility for the HIN202IB is determined by strict adherence to the following parameters: RS232 protocol, 2/2 driver/receiver configuration, full-duplex operation, 16-SOIC package format, 4.5V to 5.5V supply voltage range, and surface mount mounting type. Substitute parts are grouped into three categories based on parameter alignment:

Parametric Equivalents maintain all electrical and mechanical specifications identical to the HIN202IB, including receiver hysteresis (500 mV), data rate (120 kbps), and operating temperature range (-40°C to 85°C). These parts are direct functional replacements.

Direct Manufacturer Equivalents from alternative manufacturers (Analog Devices Inc.) meet all core functional requirements with identical package, supply voltage, and operating temperature specifications. Minor variations in receiver hysteresis (650 mV) remain within acceptable RS232 transceiver tolerances and do not affect circuit compatibility.

Similar Parts maintain core RS232 transceiver functionality, 2/2 configuration, and 16-SOIC packaging but may include variations in data rate, operating temperature range, or receiver hysteresis. These parts are suitable for applications where the specified parameter variations align with system requirements.

Engineering Selection Recommendations

For direct replacement in active production: HIN202IBZ and HIN232IBZ are the preferred substitutes. Both are manufactured by Renesas Electronics with active product status and ROHS3 compliance. HIN202IBZ maintains identical electrical specifications to the HIN202IB, including 500 mV receiver hysteresis and 120 kbps data rate across the full -40°C to 85°C operating temperature range. HIN232IBZ provides equivalent functionality with ROHS3 compliance and improved moisture sensitivity rating (MSL 2 vs. MSL 3).

For extended temperature applications: ADM232LARZ and ADM232LARZ-REEL from Analog Devices Inc. maintain the full -40°C to 85°C operating temperature range required by the HIN202IB. These parts are active products with ROHS3 compliance and unlimited moisture sensitivity (MSL 1). The 650 mV receiver hysteresis specification remains within RS232 transceiver design tolerances.

For higher data rate requirements: ADM202EARWZ and ADM202EARWZ-REEL support 230 kbps data rates while maintaining all other core specifications. These parts are suitable for applications requiring increased communication bandwidth within the RS232 protocol framework.

For commercial temperature range applications: MAX202CDW and MAX202CWE+ are suitable alternatives where the 0°C to 70°C operating temperature range meets system requirements. MAX202CDW carries Last Time Buy status; MAX202CWE+ is an active product with ROHS3 compliance.

For industrial temperature applications with relaxed specifications: ADM202JRWZ and ADM202JRWZ-REEL are not recommended as primary substitutes due to the narrower 0°C to 70°C operating temperature range, which does not meet the HIN202IB's -40°C to 85°C specification.

Frequently Asked Questions (FAQ)

Q: Can HIN202IBZ be used as a direct replacement for HIN202IB? A: Yes. HIN202IBZ is a parametric equivalent with identical electrical specifications (500 mV receiver hysteresis, 120 kbps data rate, -40°C to 85°C operating temperature) and 16-SOIC packaging. The primary difference is product status (active vs. obsolete) and ROHS3 compliance.

Q: What is the difference between ADM232LARZ and ADM202EARWZ? A: Both are Analog Devices Inc. RS232 transceivers in 16-SOIC packages with 2/2 driver/receiver configuration. ADM232LARZ operates at 120 kbps with 650 mV receiver hysteresis. ADM202EARWZ supports higher data rates (230 kbps) with the same receiver hysteresis specification. Both maintain -40°C to 85°C operating temperature range and ROHS3 compliance.

Q: Are packaging variations (Tube vs. Tape & Reel) electrically equivalent? A: Yes. Tube and Tape & Reel (TR) packaging variants of the same part number (e.g., ADM232LARZ vs. ADM232LARZ-REEL) contain identical die and electrical specifications. Packaging differences affect handling, storage, and assembly processes only.

Q: Why is receiver hysteresis specification important for substitution? A: Receiver hysteresis determines the input threshold differential for RS232 signal detection. The HIN202IB specifies 500 mV hysteresis. Substitute parts with 650 mV (ADM232LARZ, ADM202EARWZ) or 400 mV (ADM202JRWZ) hysteresis remain functionally compatible within RS232 protocol tolerances but may affect noise immunity characteristics in specific circuit implementations.

Q: Can MAX202CDW replace HIN202IB in all applications? A: MAX202CDW is electrically compatible with identical receiver hysteresis (500 mV) and data rate (120 kbps) specifications. However, the operating temperature range is limited to 0°C to 70°C, which does not meet the HIN202IB's -40°C to 85°C requirement. Use MAX202CDW only in applications where the narrower temperature range is acceptable.

Q: What does ROHS3 compliance mean for this product category? A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, and other hazardous materials. The HIN202IB is ROHS non-compliant; all listed substitute parts are ROHS3 compliant, making them suitable for applications requiring environmental compliance.

Q: Is HIN232IBZ functionally identical to HIN202IBZ? A: Yes. Both parts are Renesas Electronics RS232 transceivers with identical electrical specifications (500 mV receiver hysteresis, 120 kbps data rate, -40°C to 85°C operating temperature, 16-SOIC package). The primary difference is the base product number designation (HIN202 vs. HIN232), which reflects internal Renesas product line organization but does not affect functional compatibility.
