HIN207EIBZ RS232 5/3 Transceiver Equivalent & Substitute Parts

Part Overview

The HIN207EIBZ is a full-duplex RS232 transceiver manufactured by Renesas Electronics Corporation, configured with 5 drivers and 3 receivers in a 24-SOIC surface mount package. This component operates across the industrial temperature range of -40°C to 85°C with a 230 kbps data rate capability. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance, redesigns, and new production runs where continued supply from the original manufacturer is unavailable.

Substitute Part Grouping Explanation

Substitution eligibility for the HIN207EIBZ is determined by strict alignment across the following critical parameters:

Protocol: RS232 (full-duplex communication standard)
Configuration: 5 drivers and 3 receivers
Package: 24-SOIC form factor with identical 0.295" width (7.50mm)
Mounting: Surface mount technology
Voltage Supply: 4.75V ~ 5.25V operating range
Operating Temperature: -40°C ~ 85°C industrial range
Data Rate: 230 kbps capability

Substitute parts must maintain compatibility across all these parameters. Secondary considerations include receiver hysteresis (500 mV baseline), RoHS3 compliance, and packaging format (tube or tape & reel). Parts meeting these criteria are classified as direct substitutes regardless of manufacturer or product status.

Engineering Selection Recommendations

Selection of substitute parts for the HIN207EIBZ should prioritize active product status and extended operating temperature range where system requirements permit.

Primary Substitutes (Active Status, Extended Temperature Range): ADM207EARZ and ADM207EARZ-REEL from Analog Devices Inc. are the preferred substitutes. Both maintain the 230 kbps data rate, 5/3 driver/receiver configuration, and 24-SOIC package. These parts extend the voltage supply range to 4.5V ~ 5.5V and maintain the full -40°C ~ 85°C industrial temperature range. Active product status ensures continued availability and manufacturing support.

Secondary Substitutes (Active Status, Limited Temperature Range): MAX207CWG+, MAX207CWG+T, MAX207ECWG+, and MAX207ECWG+T from Analog Devices Inc./Maxim Integrated are active alternatives. These parts maintain voltage supply compatibility (4.75V ~ 5.25V) and receiver hysteresis (500 mV) but operate within a narrower temperature range (0°C ~ 70°C). Data rate is limited to 120 kbps. Tape & reel packaging options (MAX207CWG+T, MAX207ECWG+T) are available for high-volume production.

Tertiary Substitutes (Obsolete Status): MAX207CDW and MAX207CDWR from Texas Instruments share the voltage supply range and receiver hysteresis specifications but are classified as obsolete. These parts operate within 0°C ~ 70°C and support 120 kbps data rate. Selection of obsolete parts should be limited to applications where long-term supply agreements are established.

Limited Compatibility Substitutes: ADM207ARZ and ADM207ARZ-REEL operate at reduced data rate (120 kbps) but maintain extended temperature range (-40°C ~ 85°C) and expanded voltage supply (4.5V ~ 5.5V). These are suitable only for applications where 120 kbps performance is acceptable.

Frequently Asked Questions (FAQ)

Q: Can ADM207EARZ directly replace HIN207EIBZ in existing designs? A: Yes. ADM207EARZ maintains identical 5/3 driver/receiver configuration, 230 kbps data rate, 24-SOIC package, and -40°C ~ 85°C operating temperature. The expanded voltage supply range (4.5V ~ 5.5V versus 4.75V ~ 5.25V) provides additional design margin. Pin-to-pin compatibility is maintained.

Q: What is the impact of reduced data rate in MAX207 series substitutes? A: MAX207 variants operate at 120 kbps maximum data rate, half the HIN207EIBZ specification of 230 kbps. This limitation applies to MAX207CDW, MAX207CDWR, MAX207CWG+, MAX207CWG+T, MAX207ECWG+, and MAX207ECWG+T. Selection is appropriate only for applications with data rate requirements at or below 120 kbps.

Q: Are tape & reel packaging options functionally equivalent to tube packaging? A: Yes. Tape & reel and tube packaging formats contain identical die and electrical specifications. Packaging format selection is determined by production volume and assembly automation requirements. ADM207ARZ-REEL, ADM207EARZ-REEL, MAX207CDWR, MAX207CWG+T, and MAX207ECWG+T are tape & reel variants of their tube counterparts.

Q: What is the significance of product status (Active vs. Obsolete)? A: Active products have ongoing manufacturing support, documented availability, and stable pricing. Obsolete products have limited or no manufacturing support and may face supply constraints. HIN207EIBZ and MAX207CDW/MAX207CDWR are obsolete. ADM207 and MAX207CWG+/MAX207ECWG+ series are active.

Q: Does the expanded voltage supply range of ADM207 parts affect circuit design? A: ADM207 parts operate across 4.5V ~ 5.5V versus the HIN207EIBZ range of 4.75V ~ 5.25V. The expanded lower limit (4.5V) and upper limit (5.5V) provide additional tolerance margin. No circuit redesign is required; the parts are electrically compatible within standard 5V supply applications.

Q: How does receiver hysteresis affect substitution compatibility? A: HIN207EIBZ specifies 500 mV receiver hysteresis. ADM207 variants specify 650 mV. Both values are within standard RS232 receiver specifications and do not prevent functional substitution. The higher hysteresis in ADM207 parts provides improved noise immunity in noisy environments.

Q: Can MAX207 parts with 0°C ~ 70°C temperature range replace HIN207EIBZ in industrial applications? A: MAX207 parts are suitable only for applications operating within 0°C ~ 70°C. Industrial applications requiring -40°C ~ 85°C operation must use ADM207EARZ, ADM207EARZ-REEL, or ADM207ARZ/ADM207ARZ-REEL variants.
