SN888CDR Equivalent & Substitute Parts

Part Overview

The SN888CDR is a half-duplex RS422/RS485 transceiver manufactured by Texas Instruments, housed in an 8-SOIC surface mount package. This interface IC is designed for industrial communication applications requiring robust half-duplex serial data transmission. The part is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package footprint and functional requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SN888CDR are qualified based on strict equivalence of the following electrical and mechanical parameters:

Critical Substitution Criteria:

• Protocol support: RS422 and RS485 half-duplex operation
• Driver/Receiver configuration: 1/1 topology
• Receiver hysteresis: 60 mV
• Maximum data rate: 250 kbps
• Supply voltage range: 4.5V ~ 5.5V
• Operating temperature range: -40°C ~ 85°C
• Package type: 8-SOIC with 0.154" (3.90mm) width
• Surface mount compatibility
• Active product status
• RoHS3 compliance

The identified substitute parts maintain identical electrical performance specifications and mechanical compatibility, enabling direct substitution in applications where the SN888CDR is specified.

Parameter Comparison

Engineering Selection Recommendations

All three parts—SN888CDR, SN65HVD82DR, and SN65HVD888DR—maintain active product status with full RoHS3 compliance and REACH unaffected designation. Selection between these parts is determined by packaging availability and supply chain requirements rather than electrical or functional differences.

SN888CDR is supplied in Tape & Reel (TR) packaging with 10,300 units in stock.

SN65HVD82DR is supplied in Cut Tape (CT) & Digi-Reel® packaging with 55,300 units in stock.

SN65HVD888DR is supplied in Tape & Reel (TR) packaging with 91,988 units in stock.

All parts carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications, confirming regulatory equivalence for export and tariff purposes.

Frequently Asked Questions (FAQ)

Q: Can SN65HVD82DR replace SN888CDR in existing designs? A: Yes. Both parts maintain identical electrical specifications including RS422/RS485 protocol support, 1/1 driver/receiver configuration, 60 mV receiver hysteresis, 250 kbps data rate, 4.5V–5.5V supply range, and -40°C to 85°C operating temperature. The 8-SOIC package footprint is identical. The primary difference is packaging format (Cut Tape & Digi-Reel® versus Tape & Reel).

Q: What is the difference between SN65HVD888DR and SN888CDR? A: These parts are electrically and mechanically equivalent. Both use 8-SOIC packaging and support identical RS422/RS485 half-duplex operation. Both are supplied in Tape & Reel packaging. The base product numbers differ (65HVD888 versus 888), but functional specifications are identical.

Q: Are there packaging considerations when substituting these parts? A: Yes. SN888CDR and SN65HVD888DR are supplied in Tape & Reel (TR) format suitable for automated pick-and-place assembly. SN65HVD82DR is supplied in Cut Tape (CT) & Digi-Reel® format. Verify your assembly equipment compatibility with the selected packaging format before procurement.

Q: Do all three parts meet the same compliance standards? A: Yes. All three parts are RoHS3 compliant, REACH unaffected, and carry EAR99 ECCN classification. Moisture sensitivity level is 1 (Unlimited) for all parts, indicating no special storage or handling requirements.

Q: Which part should I select based on availability? A: Selection should be based on your packaging requirements and supply chain lead times. SN65HVD888DR has the highest inventory (91,988 units), followed by SN65HVD82DR (55,300 units) and SN888CDR (10,300 units). All parts are in active production.
