HIN202ECB RS232 Transceiver Equivalent & Substitute Parts

Part Overview

The HIN202ECB 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 system support and new designs. The HIN202ECB operates at 230 kbps data rate with a 4.5V to 5.5V supply voltage range and 0°C to 70°C operating temperature. Identifying compatible alternatives ensures design continuity and supply chain flexibility.

Substitute Part Grouping Explanation

Substitution of the HIN202ECB is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

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

Performance Parameters (allowable variance):

Data Rate: 230 kbps or higher
Receiver Hysteresis: 500 mV ±150 mV
Operating Temperature: Must include 0°C ~ 70°C range

Substitute parts are grouped into three categories: parametric equivalents (identical electrical specifications with different packaging or compliance status), upgrades (enhanced performance or temperature range), and similar alternatives (minor parameter variations within acceptable tolerances).

Engineering Selection Recommendations

Parametric Equivalents (Direct Replacement): HIN202ECBZ and HIN232ECBZ are parametrically equivalent to HIN202ECB with identical electrical specifications. Both are manufactured by Renesas, maintain the 230 kbps data rate, 500 mV receiver hysteresis, and 0°C to 70°C operating temperature. Both parts are ROHS3 compliant and active in production, providing superior supply chain availability compared to the obsolete HIN202ECB.

Upgrade Options (Enhanced Performance): MAX202IDWR and TRS202EIDWR offer extended operating temperature range (-40°C to 85°C) and ROHS3 compliance. These parts operate at 120 kbps, which is lower than the HIN202ECB's 230 kbps specification. Selection of these upgrades is appropriate only when the lower data rate meets system requirements and extended temperature operation is beneficial.

Similar Alternatives (Minor Parameter Variance): ADM202EARWZ and ADM202EARWZ-REEL (Analog Devices) maintain 230 kbps data rate and extended temperature range (-40°C to 85°C) with ROHS3 compliance. Receiver hysteresis is 650 mV, which exceeds the HIN202ECB's 500 mV specification by 150 mV. This variance remains within acceptable tolerance for RS232 transceiver applications.

ADM202JRWZ and ADM202JRWZ-REEL match the HIN202ECB's 0°C to 70°C operating temperature and 16-SOIC package. Receiver hysteresis is 400 mV, which is 100 mV lower than the HIN202ECB. Data rate is not specified for these variants.

Frequently Asked Questions (FAQ)

Q: Can HIN202ECBZ directly replace HIN202ECB? A: Yes. HIN202ECBZ is a parametric equivalent with identical electrical specifications: 230 kbps data rate, 500 mV receiver hysteresis, 4.5V to 5.5V supply, and 0°C to 70°C operating temperature. The primary difference is ROHS3 compliance and active production status.

Q: What is the difference between HIN202ECBZ and HIN232ECBZ? A: Both parts are parametrically equivalent with identical electrical and thermal specifications. The difference lies in the base product number designation (HIN202 versus HIN232), though both deliver equivalent performance for RS232 2/2 transceiver applications.

Q: Can MAX202IDWR replace HIN202ECB? A: MAX202IDWR is mechanically and electrically compatible in the 16-SOIC package with matching 4.5V to 5.5V supply and 500 mV receiver hysteresis. However, the data rate is 120 kbps versus the HIN202ECB's 230 kbps. Selection requires confirmation that the lower data rate meets system requirements.

Q: What is the significance of receiver hysteresis variance in ADM202EARWZ? A: ADM202EARWZ specifies 650 mV receiver hysteresis compared to HIN202ECB's 500 mV. This 150 mV increase provides enhanced noise immunity in RS232 applications and remains within acceptable tolerance for standard RS232 transceiver operation.

Q: Are there packaging differences between substitute parts? A: Yes. HIN202ECB, HIN202ECBZ, HIN232ECBZ, and ADM202EARWZ are supplied in Tube packaging. ADM202EARWZ-REEL, ADM202JRWZ-REEL, MAX202IDWR, and TRS202EIDWR are supplied in Tape & Reel or Cut Tape & Digi-Reel formats. Packaging selection depends on assembly process requirements and volume.

Q: Which substitute offers the best supply chain availability? A: HIN202ECBZ, HIN232ECBZ, ADM202EARWZ, ADM202EARWZ-REEL, ADM202JRWZ, and ADM202JRWZ-REEL are all active in production. MAX202IDWR and TRS202EIDWR are obsolete. Active parts provide superior long-term availability.

Q: Is RoHS compliance required for my application? A: HIN202ECB is RoHS non-compliant. All substitute parts listed are ROHS3 compliant. If RoHS compliance is a design requirement, any of the listed substitutes satisfy this criterion.
