Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the XR3085XED-F is determined by strict equivalence across the following critical parameters:

• Protocol Compatibility: RS422/RS485 half-duplex operation
• Electrical Configuration: 1/1 driver/receiver topology
• Receiver Hysteresis: 25 mV threshold
• Data Rate: 1 Mbps maximum
• Supply Voltage Range: 4.5V ~ 5.5V
• Package / Case: 8-SOIC form factor with identical pinout
• Mounting Type: Surface mount technology

The XR3085XID-F meets all substitution criteria. Both parts share identical electrical specifications, protocol support, and physical packaging. The primary distinction is product status: XR3085XID-F is active production, whereas XR3085XED-F is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The XR3085XID-F is the direct substitute for the obsolete XR3085XED-F. Both parts are manufactured by MaxLinear, Inc., and share identical electrical and mechanical specifications across all critical parameters.

Substitution Considerations:

The XR3085XID-F operates within an operating temperature range of -40°C to 85°C, compared to the XR3085XED-F range of -40°C to 125°C. Applications requiring operation above 85°C must evaluate this temperature differential against system thermal requirements.

The XR3085XID-F carries ROHS3 compliance and REACH unaffected status, providing regulatory alignment for modern manufacturing and distribution environments. The XR3085XED-F product status is obsolete, making the XR3085XID-F the recommended active production alternative.

Both parts are supplied in 8-SOIC packaging with identical pinout and footprint, enabling direct PCB-level substitution without layout modification.

Frequently Asked Questions (FAQ)

Q: Can the XR3085XID-F replace the XR3085XED-F in existing designs?

A: Yes. The XR3085XID-F is electrically and mechanically equivalent to the XR3085XED-F across all specified parameters: RS422/RS485 protocol, 1/1 half-duplex configuration, 25 mV receiver hysteresis, 1 Mbps data rate, 4.5V to 5.5V supply voltage, and 8-SOIC package. Direct substitution is supported at the PCB level without design modification.

Q: What is the temperature operating range difference?

A: The XR3085XED-F operates from -40°C to 125°C, while the XR3085XID-F operates from -40°C to 85°C. Applications requiring sustained operation above 85°C must confirm thermal compatibility with the substitute part's specifications.

Q: Are there packaging differences between these parts?

A: No. Both the XR3085XED-F and XR3085XID-F are supplied in 8-SOIC (0.154", 3.90mm width) surface mount packages with identical pinout and footprint. The XR3085XID-F is supplied in tube packaging, while the XR3085XED-F packaging type is not specified.

Q: Why is the XR3085XED-F marked as obsolete?

A: The XR3085XED-F carries an obsolete product status designation. The XR3085XID-F is the active production equivalent from MaxLinear, Inc., and is recommended for new designs and ongoing production support.

Q: Does the XR3085XID-F meet current regulatory requirements?

A: Yes. The XR3085XID-F is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component manufacturing and distribution.
