Substitute Part Grouping Explanation

Substitute parts for the NBA3N201SDG are determined by strict equivalence across the following critical parameters:

• Protocol: LVDS, Multipoint
• Number of Drivers/Receivers: 1/1 configuration
• Duplex Mode: Half-duplex operation
• Data Rate: 200 Mbps
• Voltage Supply Range: 3V to 3.6V
• Operating Temperature Range: -40°C to 125°C
• Receiver Hysteresis: 25 mV
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute parts NBA3N200SDG and NBA3N206SDG meet all specified electrical and mechanical parameters, enabling direct functional replacement in applications originally designed for the NBA3N201SDG.

Parameter Comparison

Engineering Selection Recommendations

All three parts—NBA3N201SDG, NBA3N200SDG, and NBA3N206SDG—are classified as obsolete products. Selection among these equivalents should be based on current inventory availability and procurement lead times. All parts maintain ROHS3 compliance and identical electrical specifications, ensuring functional interchangeability in circuit designs. The 8-SOIC package footprint is consistent across all variants, permitting direct PCB layout compatibility without redesign. Moisture sensitivity level 1 (unlimited) indicates no special storage or handling requirements beyond standard component practices.

Frequently Asked Questions (FAQ)

Q: Can NBA3N200SDG replace NBA3N201SDG in existing designs? A: Yes. NBA3N200SDG meets all electrical and mechanical specifications of NBA3N201SDG, including protocol, data rate, voltage supply range, operating temperature, and 8-SOIC package configuration. Direct substitution is supported without circuit modification.

Q: Are there differences in packaging between these substitute parts? A: All three parts use identical 8-SOIC (0.154", 3.90mm Width) surface mount packages. PCB footprints and land patterns are compatible across NBA3N201SDG, NBA3N200SDG, and NBA3N206SDG.

Q: What is the significance of the product status being obsolete? A: Obsolete status indicates these parts are no longer manufactured. Substitute selection should prioritize current inventory availability. All three parts share identical specifications, so procurement should focus on lead time and stock levels.

Q: Do all substitute parts have the same compliance certifications? A: Yes. NBA3N201SDG, NBA3N200SDG, and NBA3N206SDG are all ROHS3 compliant and REACH unaffected, with identical moisture sensitivity levels and electrical certifications.

Q: Is the 25 mV receiver hysteresis specification consistent across all parts? A: Yes. All three transceiver variants maintain 25 mV receiver hysteresis, ensuring equivalent signal integrity performance in multipoint LVDS applications.
