Engineering Selection Recommendations
Parametric Equivalents (Preferred for Direct Replacement):
HIN202ECBNZ and HIN232ACBNZ are parametric equivalents manufactured by Renesas Electronics Corporation. Both parts maintain identical electrical specifications to the HIN232ACBN while offering active product status and ROHS3 compliance. These parts are the primary choice for applications requiring direct functional replacement with improved regulatory compliance.
Similar Parts (Acceptable with Design Verification):
Analog Devices ADM232 series parts (ADM232AARNZ-REEL, ADM232AARNZ-REEL7, ADM232LARZ, ADM232LARZ-REEL) and Linear Technology LT1081 series parts (LT1081CSW#PBF, LT1081CSW#TRPBF, LT1081ISW#PBF) provide functional RS232 transceiver capability with 2/2 driver/receiver configuration and 4.5V to 5.5V supply voltage compatibility. These parts feature extended operating temperature ranges (-40°C to 85°C) and ROHS3 compliance. Data rate performance ranges from 120 kbps to 250 kbps, all meeting or exceeding the 230 kbps requirement of the original part.
Packaging Considerations:
The original HIN232ACBN uses a 16-SOIC package with 0.154" width. Parametric equivalents maintain this footprint. Similar parts from Analog Devices ADM232LARZ series use a wider 16-SOIC package (0.295" width) requiring PCB layout verification. Linear Technology LT1081 series also uses the 0.295" width package. Footprint compatibility must be confirmed before selection.
Compliance and Availability:
The HIN232ACBN is obsolete and RoHS non-compliant. All recommended substitutes are active products with ROHS3 compliance, suitable for new designs and long-term supply chain stability.
Frequently Asked Questions (FAQ)
Q: Can HIN202ECBNZ directly replace HIN232ACBN?
A: Yes. HIN202ECBNZ is a parametric equivalent with identical electrical specifications (2/2 RS232 transceiver, 230 kbps, 4.5V-5.5V supply, 0°C-70°C operating range) in the same 16-SOIC (0.154") package. The primary differences are active product status and ROHS3 compliance.
Q: What is the difference between HIN232ACBNZ and HIN202ECBNZ?
A: Both are parametric equivalents with identical electrical performance. HIN232ACBNZ is based on the HIN232 base product number, while HIN202ECBNZ is based on HIN202. Both offer active status and ROHS3 compliance. Selection between them depends on design preference and supply availability.
Q: Can ADM232 or LT1081 parts be used as substitutes?
A: Yes, with design verification. These parts maintain RS232 protocol, 2/2 driver/receiver configuration, and 4.5V-5.5V supply voltage compatibility. However, they feature different package widths (0.295" vs. 0.154"), extended operating temperature ranges, and data rates ranging from 120 kbps to 250 kbps. PCB layout must accommodate the wider package footprint.
Q: What is the significance of the package width difference (0.154" vs. 0.295")?
A: Package width affects PCB footprint and pin spacing. The original HIN232ACBN uses a narrower 0.154" 16-SOIC package. Substitutes with 0.295" width require different PCB land patterns and cannot be used as direct drop-in replacements without layout modification.
Q: Are all substitute parts RoHS compliant?
A: Yes. All recommended substitute parts carry ROHS3 compliance certification, whereas the original HIN232ACBN is RoHS non-compliant. This makes substitutes suitable for applications with RoHS regulatory requirements.
Q: What data rate should I select?
A: The original HIN232ACBN operates at 230 kbps. All recommended substitutes meet or exceed this specification. ADM232 series parts operate at 120-200 kbps, and LT1081 series parts operate at 250 kbps. Selection depends on application bandwidth requirements and supply availability.
Q: Can I use parts with extended operating temperature ranges?
A: Yes. The original HIN232ACBN operates from 0°C to 70°C. Substitutes with extended ranges (-40°C to 85°C) are backward compatible and provide additional thermal margin. This is beneficial for applications in variable environmental conditions.
Q: What packaging options are available?
A: Parametric equivalents (HIN202ECBNZ, HIN232ACBNZ) are available in Tube packaging. ADM232 series parts are available in Cut Tape (CT) & Digi-Reel or Tube packaging. LT1081 series parts are available in Tube or Tape & Reel (TR) packaging. Selection depends on procurement volume and handling requirements.
