XR3175EID-F Equivalent & Substitute Parts

Part Overview

The XR3175EID-F is a half-duplex RS422/RS485 transceiver manufactured by MaxLinear, Inc., housed in an 8-SOIC surface mount package. This device functions as a 1/1 transceiver with a 500 kbps data rate and operates across a 3V to 3.6V supply voltage range. The part is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the XR3175EID-F is determined by the following critical parameters:

Package Compatibility: All substitutes must use the 8-SOIC (0.154", 3.90mm Width) surface mount package
Protocol Support: All substitutes must support RS422 and RS485 protocols
Transceiver Configuration: All substitutes must be 1/1 half-duplex transceivers
Supply Voltage: All substitutes must operate within the 3V to 3.6V range
Operating Temperature: All substitutes must support -40°C to 85°C operation
Data Rate Compatibility: Substitutes with data rates equal to or greater than 500 kbps are functionally compatible

The five substitute parts listed below meet all mandatory compatibility criteria. Differences in receiver hysteresis (15 mV vs. 25 mV) and data rate enhancements do not prevent substitution, as these represent equal or improved performance characteristics.

Engineering Selection Recommendations

All five substitute parts are manufactured by Renesas Electronics Corporation and carry active product status, ensuring long-term availability and supply chain stability. Each substitute is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

ISL3175EIBZ and ISL3175EIBZ-T provide the closest functional match to the XR3175EID-F, maintaining the 500 kbps data rate while offering improved receiver hysteresis (15 mV) and active product status. These parts differ only in packaging format: ISL3175EIBZ is supplied in Tube packaging, while ISL3175EIBZ-T is supplied in Cut Tape (CT) & Digi-Reel® format.

ISL3178EIBZ-T7A offers enhanced performance with a 20 Mbps data rate, suitable for applications requiring higher bandwidth while maintaining full backward compatibility with the original 500 kbps specification.

ISL3172EIBZ-T7A and ISL83072EIBZA-T7A operate at 250 kbps, which is below the original 500 kbps specification. These parts are suitable only for applications where the lower data rate does not impact system performance.

Frequently Asked Questions (FAQ)

Q: Can I use ISL3172EIBZ-T7A or ISL83072EIBZA-T7A as direct replacements for XR3175EID-F?

A: These parts are electrically compatible but operate at 250 kbps, which is half the original 500 kbps data rate. They are suitable only if your application does not require the full 500 kbps bandwidth.

Q: What is the difference between ISL3175EIBZ and ISL3175EIBZ-T?

A: Both parts are functionally identical. The difference is packaging: ISL3175EIBZ is supplied in Tube format, while ISL3175EIBZ-T is supplied in Cut Tape (CT) & Digi-Reel® format. Select based on your procurement and assembly requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes, all five substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental regulations.

Q: Does the 15 mV receiver hysteresis in substitute parts affect compatibility?

A: No. The 15 mV hysteresis in Renesas parts represents improved performance compared to the original 25 mV specification and does not prevent substitution.

Q: Can I use ISL3178EIBZ-T7A if my application only requires 500 kbps?

A: Yes. ISL3178EIBZ-T7A operates at 20 Mbps, which exceeds the 500 kbps requirement. It is fully backward compatible and can be used in applications designed for the original 500 kbps specification.

Q: What is the moisture sensitivity difference between the original and substitute parts?

A: The XR3175EID-F has MSL 1 (unlimited), while all Renesas substitutes have MSL 3 (168 hours). MSL 3 requires storage in dry conditions and limits the time between component removal from packaging and soldering to 168 hours. Ensure your manufacturing process accommodates this requirement.
