DS320PR810NJXR PCIe 5.0 Buffer ReDriver Equivalent & Substitute Parts

Part Overview

The DS320PR810NJXR is an active Buffer ReDriver interface component manufactured by Texas Instruments, designed for PCIe 5.0 applications requiring high-speed signal conditioning. This 8-channel device operates at 32 Gbps per channel and provides input equalization for differential signal paths. The part is currently in Active product status with 2,300 units available in new original inventory.

Identifying equivalent and substitute parts is necessary when primary inventory becomes unavailable, when alternative packaging formats are required for specific manufacturing processes, or when supply chain optimization requires component standardization across production batches.

Substitute Part Grouping Explanation

Substitution eligibility for the DS320PR810NJXR is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Data Rate (Max): 32 Gbps
• Number of Channels: 8
• Input/Output Configuration: Differential / Differential
• Signal Conditioning: Input Equalization
• Delay Time: 0.1 ns
• Capacitance - Input: 1.6 pF
• Voltage - Supply: 3V ~ 3.6V
• Operating Temperature: -40°C ~ 85°C (TA)

Mechanical Equivalence Requirements:

• Package / Case: 64-WFQFN Exposed Pad
• Mounting Type: Surface Mount
• Supplier Device Package: 64-WQFN (5.5x10)

Packaging Format Variation: The primary distinction between the main part and its substitute relates to packaging format (Tape & Reel versus standard packaging). This variation does not affect electrical performance or mechanical compatibility but impacts supply chain logistics and manufacturing processes.

Parameter Comparison

Engineering Selection Recommendations

Substitution Validity: The DS320PR810NJXT is a parametric equivalent to the DS320PR810NJXR. Both parts are manufactured by Texas Instruments, maintain Active product status, and are electrically and mechanically identical across all specified parameters.

Packaging Format Consideration: The DS320PR810NJXT is supplied in Tape & Reel (TR) format, while the DS320PR810NJXR uses standard packaging. This distinction affects manufacturing workflow and component handling but does not impact electrical performance or PCB assembly compatibility. Selection between these formats depends on production volume requirements and automated assembly equipment specifications.

Compliance and Certification: Both parts carry identical compliance designations: REACH Unaffected, ECCN EAR99, and HTSUS 8542.39.0001. Both maintain MSL 2 (1 Year) moisture sensitivity classification, requiring equivalent handling and storage protocols.

Inventory Availability: The DS320PR810NJXR maintains higher inventory availability (2,300 units) compared to the DS320PR810NJXT (772 units). Selection should account for project timeline and supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can DS320PR810NJXT be used as a direct replacement for DS320PR810NJXR in PCIe 5.0 applications?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical electrical specifications including 32 Gbps data rate, 8-channel configuration, differential input/output, input equalization, 0.1 ns delay time, 1.6 pF input capacitance, 3V-3.6V supply voltage, and -40°C to 85°C operating temperature range. Both use the 64-WFQFN (5.5x10) package with exposed pad.

Q: What is the difference between DS320PR810NJXR and DS320PR810NJXT?

A: The primary difference is packaging format. DS320PR810NJXR uses standard packaging, while DS320PR810NJXT is supplied in Tape & Reel (TR) format. This affects supply chain logistics and automated assembly processes but does not alter electrical performance or physical compatibility on the PCB.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical compliance designations: REACH Unaffected, ECCN EAR99, and HTSUS 8542.39.0001. Both maintain MSL 2 (1 Year) moisture sensitivity classification.

Q: Which part should be selected for high-volume production?

A: Selection depends on manufacturing equipment and process requirements. Tape & Reel format (DS320PR810NJXT) is typically preferred for automated pick-and-place assembly at high volumes. Standard packaging (DS320PR810NJXR) may be suitable for lower-volume or manual assembly processes. Both formats are compatible with standard PCB assembly workflows.

Q: Are the propagation delay and input equalization characteristics identical?

A: Yes. Both parts specify 0.1 ns delay time and input equalization signal conditioning. These parameters are critical for PCIe 5.0 signal integrity and are identical across both part numbers.

Q: What is the moisture sensitivity requirement for storage and handling?

A: Both parts are classified as MSL 2 (1 Year). This requires storage in controlled humidity environments and adherence to standard moisture sensitivity handling procedures. Components must be used within one year of packaging date under specified storage conditions.
