- Electrical interface: 1/1 driver/receiver configuration
- Package compatibility: 14-SOIC form factor with 0.154" (3.90mm) width
- Supply voltage range: Minimum 4.5V to 5.5V operation
- Operating temperature range: Support for -40°C to 85°C minimum
- Data rate capability: Minimum 20Mbps support
Substitute parts are grouped into two categories based on these constraints:
Category A - Direct Substitutes (Full Parameter Alignment): Parts meeting all critical parameters with active product status and modern compliance certifications (ROHS3, REACH).
Category B - Conditional Substitutes (Parameter Deviations): Parts with acceptable deviations in receiver hysteresis, data rate, or operating temperature range that remain functionally compatible within the XR3086XID-F's specified operating envelope.

Engineering Selection Recommendations
Primary Substitutes (Active Status, Full Compliance):
LTC2864IS-1#PBF is the recommended primary substitute. It maintains RS422/RS485 full-duplex 1/1 transceiver architecture with 20Mbps data rate capability, matching the XR3086XID-F's core functionality. The part is ROHS3 compliant and REACH unaffected, with active product status ensuring long-term availability. The extended supply voltage range (3V to 5.5V) provides additional design flexibility. Receiver hysteresis of 150mV is higher than the original 25mV but remains within acceptable noise immunity parameters for standard RS422/RS485 applications.
MAX13086EESD+ provides an alternative with matching -40°C to 85°C operating temperature range and identical supply voltage specification. Data rate is specified at 16Mbps, which is below the XR3086XID-F's 20Mbps but sufficient for most legacy serial communication protocols. ROHS3 compliance and active product status support long-term production viability.
Secondary Substitutes (Conditional Suitability):
MAX13080EESD+ and MAX13080EESD+T are suitable for applications where data rate requirements do not exceed 250kbps. Both maintain the -40°C to 85°C operating temperature range and 4.5V to 5.5V supply specification. The primary distinction is packaging: MAX13080EESD+ is supplied in tube format, while MAX13080EESD+T uses cut tape and Digi-Reel format. Both are ROHS3 compliant with active product status.
MAX13080EASD+ extends the upper operating temperature to 125°C, suitable for high-temperature environments. However, the operating temperature minimum is -40°C and maximum is 125°C, which exceeds the XR3086XID-F specification. This part is appropriate only when extended temperature operation is required.
MAX13080ECSD+ and MAX13080ECSD+T are restricted to 0°C to 70°C operating range and are suitable only for commercial-grade applications that do not require the full -40°C to 85°C industrial temperature range.
MAX13083EESD+ maintains identical electrical and thermal specifications to MAX13080EESD+ with different internal architecture. Selection between MAX13080 and MAX13083 variants depends on specific application requirements not specified in the provided parameters.
Frequently Asked Questions (FAQ)
Q: Can LTC2864IS-1#PBF directly replace XR3086XID-F without circuit modifications?
A: LTC2864IS-1#PBF is pin-compatible within the 14-SOIC package and maintains RS422/RS485 full-duplex 1/1 transceiver functionality. The 20Mbps data rate matches the original specification. The higher receiver hysteresis (150mV vs. 25mV) may require signal integrity verification in noise-sensitive applications, but does not prevent direct substitution in standard industrial serial communication circuits.
Q: What is the primary limitation of MAX13080 series parts compared to XR3086XID-F?
A: MAX13080 series parts are specified with a maximum data rate of 250kbps, significantly below the XR3086XID-F's 20Mbps capability. These parts are suitable only for low-speed serial communication applications. For high-speed RS422/RS485 networks, MAX13086 series parts are required.
Q: Are MAX13080ECSD+ and MAX13080ECSD+T suitable for industrial applications?
A: MAX13080ECSD+ and MAX13080ECSD+T are rated for 0°C to 70°C operating temperature, which is the commercial grade specification. The XR3086XID-F operates across -40°C to 85°C, covering the full industrial temperature range. These parts are not recommended for applications requiring extended low-temperature operation below 0°C or sustained operation above 70°C.
Q: What is the difference between tube and tape & reel packaging options?
A: Tube packaging (MAX13080EESD+, MAX13086EESD+) is suitable for lower-volume production and manual assembly. Tape & Reel and Cut Tape formats (MAX13080EESD+T, MAX13080ECSD+T, MAX13086EASD+) are optimized for automated pick-and-place assembly. Electrical and thermal specifications are identical; packaging selection depends on manufacturing process requirements.
Q: Can MAX13086EASD+ be used in applications requiring -40°C operation?
A: MAX13086EASD+ is rated for -40°C to 125°C operating temperature, which exceeds the XR3086XID-F's -40°C to 85°C range. It is fully suitable for applications requiring the full -40°C to 85°C industrial temperature specification and provides additional margin for high-temperature environments up to 125°C.
Q: What compliance certifications should be verified for new production designs?
A: All active substitute parts listed are ROHS3 compliant and REACH unaffected. These certifications are mandatory for products sold in the European Union and many other regulated markets. The obsolete XR3086XID-F does not carry these certifications, making the transition to compliant alternatives necessary for new production runs and long-term supply chain sustainability.
