Engineering Selection Recommendations

For applications requiring direct replacement of the MAX213ECAI with active product status and current compliance certifications, the MAX213ECAI+ from Analog Devices Inc./Maxim Integrated is the primary selection. This part maintains identical electrical specifications while offering ROHS3 compliance and active manufacturing status.

Alternative active parts within the Analog Devices portfolio include MAX211CAI+, MAX211ECAI+, MAX213CAI+, MAX241CAI+, and MAX241ECAI+. All maintain the required 4/4 driver/receiver configuration, 120 Kbps data rate, and 28-SSOP packaging.

For cross-manufacturer compatibility, HIN213ECAZ-T from Renesas Electronics Corporation provides equivalent specifications with active product status and ROHS3 compliance. The HIN213EIAZ-T variant offers extended operating temperature range (-40°C to 85°C) and higher data rate (230 Kbps), suitable for applications requiring enhanced environmental performance.

Obsolete alternatives MAX213CDBR (Texas Instruments) and MAX213IDB (Texas Instruments) are available but not recommended for new designs. MAX213IDB provides extended temperature operation (-40°C to 85°C) if required for legacy system maintenance.

Frequently Asked Questions (FAQ)

Q: Can MAX213ECAI be directly replaced with MAX213ECAI+?

A: Yes. Both parts share identical electrical specifications, 4/4 driver/receiver configuration, 120 Kbps data rate, 4.5V to 5.5V supply voltage, and 28-SSOP packaging. The primary difference is product status and compliance certification; MAX213ECAI+ is active and ROHS3 compliant.

Q: What is the difference between MAX211 and MAX213 series parts?

A: Both series maintain identical core specifications for this application: 4/4 driver/receiver configuration, 120 Kbps data rate, full-duplex RS232 operation, and 28-SSOP packaging. Selection between series is based on availability and compliance requirements rather than functional differences.

Q: Is HIN213EIAZ-T a suitable substitute if higher data rate is required?

A: HIN213EIAZ-T supports 230 Kbps data rate and extended operating temperature (-40°C to 85°C) compared to the MAX213ECAI specification of 120 Kbps and 0°C to 70°C. This part is functionally compatible for applications requiring enhanced performance within the same 28-SSOP package and 4.5V to 5.5V supply range.

Q: Are there packaging differences between substitute parts?

A: All listed substitute parts use 28-SSOP (0.209", 5.30mm Width) surface mount packaging, identical to the MAX213ECAI. Packaging is consistent across all alternatives, allowing direct PCB compatibility.

Q: What is the significance of RoHS compliance status?

A: The MAX213ECAI is RoHS non-compliant. Active substitute parts (MAX213ECAI+, MAX211CAI+, MAX211ECAI+, MAX213CAI+, MAX241CAI+, MAX241ECAI+, HIN213ECAZ-T, HIN213EIAZ-T) are ROHS3 compliant, meeting current environmental and regulatory requirements for new designs and manufacturing.

Q: Can MAX213IDB be used as a replacement despite obsolete status?

A: MAX213IDB is functionally compatible with identical 4/4 driver/receiver configuration, 120 Kbps data rate, and 28-SSOP packaging. However, it is classified as obsolete. This part is suitable only for legacy system maintenance where extended operating temperature (-40°C to 85°C) is required and active alternatives are unavailable.
