SN65HVD82DR Equivalent & Substitute Parts

Part Overview

The SN65HVD82DR is a half-duplex RS422/RS485 transceiver interface IC manufactured by Texas Instruments. This device functions as a 1/1 driver/receiver configuration in an 8-SOIC surface mount package, designed for industrial and commercial serial communication applications. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical specifications, mechanical packaging, and compliance certifications align with the original component, enabling direct replacement in circuit designs without functional degradation.

Substitute Part Grouping Explanation

Substitution eligibility for the SN65HVD82DR is determined by strict equivalence across the following critical parameters:

  • Protocol support (RS422/RS485 half-duplex operation)
  • Driver/receiver configuration (1/1)
  • Data rate specification (250 kbps)
  • Supply voltage range (4.5V to 5.5V)
  • Operating temperature range (-40°C to 85°C)
  • Receiver hysteresis (60 mV)
  • Package and pinout compatibility (8-SOIC)
  • Compliance certifications (RoHS3, REACH Unaffected, EAR99)

All identified substitute parts meet these criteria without exception. Packaging format differences (Cut Tape vs. Tape & Reel) do not affect electrical or mechanical compatibility and represent only supply chain variations.

Engineering Selection Recommendations

All three parts—SN65HVD82DR, SN65HVD888DR, and SN888CDR—are Active status components with identical electrical specifications and full compliance certifications. Selection between these parts is determined by supply chain availability and packaging requirements rather than technical performance:

  • SN65HVD82DR: Available in Cut Tape and Digi-Reel packaging formats (55,300 units in stock)
  • SN65HVD888DR: Available in Tape & Reel format (91,988 units in stock)
  • SN888CDR: Available in Tape & Reel format (10,300 units in stock)

All parts satisfy RoHS3, REACH, and EAR99 compliance requirements. Direct substitution is permissible without design modification or functional impact.

Frequently Asked Questions (FAQ)

Q: Can SN65HVD888DR replace SN65HVD82DR in production?

A: Yes. Both parts are electrically identical with matching protocol support, data rate, voltage range, temperature range, and receiver hysteresis specifications. The only difference is packaging format (Tape & Reel vs. Cut Tape/Digi-Reel). Pinout and 8-SOIC package dimensions are identical.

Q: What is the difference between SN888CDR and SN65HVD888DR?

A: Both parts are functionally equivalent with identical electrical specifications and 8-SOIC packaging. The base product number differs (SN888 vs. 65HVD888), but all critical parameters—protocol, data rate, voltage, temperature, hysteresis, and compliance—are equivalent.

Q: Are packaging format differences significant for substitution?

A: Packaging format (Cut Tape, Digi-Reel, or Tape & Reel) affects supply chain handling and component presentation only. It does not impact electrical performance, pinout compatibility, or mechanical fit on PCBs. All formats are suitable for automated assembly.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. SN65HVD82DR, SN65HVD888DR, and SN888CDR all carry RoHS3 compliance, REACH Unaffected status, and EAR99 classification. Moisture sensitivity level is 1 (Unlimited) for all parts.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. Identical pinout, package dimensions, electrical specifications, and compliance certifications enable direct substitution without PCB redesign or firmware modification.
