HIN206CB RS232 Transceiver Equivalent & Substitute Parts

Part Overview

The HIN206CB is a 4/3 full-duplex RS232 transceiver manufactured by Renesas Electronics Corporation in 24-SOIC surface mount packaging. This interface IC operates across the 4.5V to 5.5V supply range with a 120 kbps data rate and 500 mV receiver hysteresis. The HIN206CB is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support, maintenance, and new design implementations where RS232 transceiver functionality is required.

Substitute Part Grouping Explanation

Substitution of the HIN206CB is determined by strict equivalence across the following critical parameters:

Protocol: RS232
Number of Drivers/Receivers: 4/3
Duplex: Full
Voltage Supply Range: 4.5V ~ 5.5V
Package / Case: 24-SOIC (0.295", 7.50mm Width)
Mounting Type: Surface Mount
Receiver Hysteresis: 500 mV (direct equivalents) or 650 mV (functional equivalents with extended operating temperature)
Data Rate: 120 kbps (direct equivalents) or higher (functional equivalents)

Substitute parts are grouped into three categories:

Direct Manufacturer Equivalents: Parts with identical electrical specifications including 500 mV receiver hysteresis, 120 kbps data rate, and 0°C to 70°C operating temperature range. These parts are pin-compatible and parameter-matched.

Similar Functional Equivalents: Parts with the same 4/3 transceiver configuration and RS232 protocol but with extended operating temperature ranges (-40°C to 85°C), higher receiver hysteresis (650 mV), or higher data rates (230 kbps). These parts provide enhanced performance characteristics while maintaining functional compatibility.

Parametric Equivalents: Parts meeting all critical electrical and mechanical parameters with variations in packaging format (tube versus tape & reel) or minor specification differences that do not affect circuit-level compatibility.

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications):

Select MAX206CWG+T, MAX206CWG+, MAX206ECWG+T, or MAX206ECWG+ when the application requires exact parameter matching with the HIN206CB, including 500 mV receiver hysteresis, 120 kbps data rate, and 0°C to 70°C operating temperature. All substitute options are active products with ROHS3 compliance, providing improved regulatory status compared to the obsolete HIN206CB. Choose tape & reel packaging (MAX206CWG+T, MAX206ECWG+T) for high-volume production or tube packaging (MAX206CWG+, MAX206ECWG+) for lower-volume applications.

For Extended Operating Temperature Range:

Select MAX206EEWG+T or MAX206EEWG+ when the application requires operation across -40°C to 85°C. These parts maintain the 500 mV receiver hysteresis and 120 kbps data rate while extending the lower operating temperature limit by 40°C and the upper limit by 15°C. This selection is appropriate for industrial or automotive environments with wider temperature requirements.

For Enhanced Performance with Extended Temperature:

Select ADM206EARZ-REEL or ADM206EARZ when the application benefits from 230 kbps data rate capability and -40°C to 85°C operating temperature range. The 650 mV receiver hysteresis provides increased noise immunity compared to the HIN206CB specification. These parts are suitable for applications requiring higher data throughput or operation in extended temperature environments.

For Cost-Optimized Extended Temperature:

Select ADM206ARZ-REEL or ADM206ARZ when extended temperature operation (-40°C to 85°C) is required without the higher data rate specification. The 650 mV receiver hysteresis maintains functional compatibility while providing enhanced noise margin.

All recommended substitutes are active products with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), ensuring long-term availability and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can MAX206EEWG+ directly replace HIN206CB in existing designs?

A: Yes. MAX206EEWG+ is a direct functional equivalent with identical electrical specifications (4/3 transceiver, RS232 protocol, 500 mV receiver hysteresis, 120 kbps data rate, 4.5V to 5.5V supply) and the same 24-SOIC package. The extended operating temperature range (-40°C to 85°C versus 0°C to 70°C) provides additional capability without affecting circuit compatibility. Pin configuration and signal timing are equivalent.

Q: What is the difference between MAX206CWG+ and MAX206CWG+T?

A: Both parts are electrically identical with the same specifications. The difference is packaging format: MAX206CWG+ is supplied in tube packaging, while MAX206CWG+T is supplied in tape & reel format. Tape & reel packaging is standard for automated assembly and high-volume production. Tube packaging is typical for lower-volume or manual assembly applications.

Q: Why do ADM206 parts have 650 mV receiver hysteresis instead of 500 mV?

A: The ADM206 series specifies 650 mV receiver hysteresis, which is a higher threshold than the HIN206CB's 500 mV. Higher hysteresis provides increased noise immunity and improved signal discrimination in noisy environments. This specification difference does not prevent functional substitution in RS232 applications, as both values fall within standard RS232 receiver specifications.

Q: Can ADM206EARZ be used if the application only requires 120 kbps operation?

A: Yes. ADM206EARZ is rated for 230 kbps data rate, which exceeds the 120 kbps requirement of the HIN206CB. The part operates correctly at lower data rates. The higher data rate capability does not affect operation at 120 kbps or lower speeds.

Q: What is the advantage of selecting MAX206EEWG+T over MAX206CWG+T?

A: MAX206EEWG+T extends the operating temperature range to -40°C to 85°C compared to MAX206CWG+T's 0°C to 70°C range. If the application operates only within 0°C to 70°C, both parts are equivalent. If the application requires operation below 0°C or above 70°C, MAX206EEWG+T is required.

Q: Are all substitute parts RoHS compliant?

A: Yes. All recommended substitute parts are ROHS3 compliant. The original HIN206CB is RoHS non-compliant. Selecting any active substitute part improves regulatory compliance for new designs or system updates.

Q: Can I mix packaging formats (tube and tape & reel) in the same production run?

A: Electrically, yes. Tube and tape & reel versions of the same part number are functionally identical. However, production logistics typically require consistent packaging format for automated assembly. Mixing formats may require separate assembly line setup or manual handling, increasing production complexity.

Q: What is the inventory status of substitute parts?

A: All recommended substitute parts are active products with current inventory availability ranging from 671 to 1910 pieces in stock, ensuring reliable supply for both prototype and production quantities.
