Key Parameters

Substitute Part Grouping Explanation

Substitution of the ISL32273EFVZ is determined by strict equivalence across the following critical parameters:

• Protocol support: RS422 and RS485 compatibility
• Receiver configuration: 0 drivers / 4 receivers
• Receiver hysteresis: 30 mV
• Data rate: 20Mbps minimum
• Supply voltage range: 3V to 5.5V
• Operating temperature range: -40°C to 125°C
• Package type: 16-TSSOP surface mount
• Compliance: ROHS3 and REACH requirements

The ISL32275EFVZ meets all these criteria and qualifies as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the ISL32273EFVZ and ISL32275EFVZ are active products from Renesas Electronics Corporation with identical electrical and mechanical specifications. Both components are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. Selection between these parts can be based on inventory availability and supply chain considerations, as they are functionally interchangeable within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can ISL32275EFVZ replace ISL32273EFVZ in existing designs? A: Yes. Both parts share identical electrical specifications, receiver configuration, data rate, supply voltage range, operating temperature range, and 16-TSSOP package dimensions. Direct substitution is supported without circuit modification.

Q: Are there any differences in compliance or certifications? A: No. Both parts carry identical ROHS3 compliance status, REACH unaffected designation, and MSL rating of 2 (1 Year).

Q: What determines compatibility between these receiver ICs? A: Compatibility is determined by matching protocol support (RS422/RS485), receiver count (0/4 configuration), hysteresis specification (30 mV), data rate (20Mbps), supply voltage range (3V–5.5V), operating temperature range (-40°C to 125°C), and package type (16-TSSOP).

Q: Are there any package or pinout considerations? A: Both parts use the 16-TSSOP surface mount package with identical 0.173" width and 4.40mm dimensions. Pinout compatibility is maintained for direct board-level substitution.
