Engineering Selection Recommendations
Primary Substitutes (Identical Electrical and Mechanical Specifications):
MAX213EEWI+ and MAX211IDWR are direct parametric equivalents with identical electrical specifications and 28-SOIC packaging. Both are active products with ROHS3 compliance and unlimited moisture sensitivity. MAX213EEWI+ is supplied in Tube packaging, while MAX211IDWR is supplied in Tape & Reel format. Selection between these depends on packaging requirements and inventory availability.
Alternative with Enhanced Data Rate:
HIN213EIBZ (Renesas Electronics Corporation) maintains identical electrical specifications with the exception of data rate (230kbps versus 120Kbps). This part is backward compatible for applications not requiring the full 230kbps capability. Moisture sensitivity level is MSL 3 (168 Hours) versus MSL 1 (Unlimited) for the original part.
Substitutes with Modified Receiver Hysteresis:
ADM213ARZ, ADM213ARZ-REEL, and ADM213EARZ feature 650 mV receiver hysteresis compared to the original 500 mV specification. ADM213EARZ and ADM213EARZ-REEL offer enhanced data rate capability (230kbps). These parts are suitable for applications where increased hysteresis does not impact system performance.
Package Variant:
TRS213IDBR is a Texas Instruments active product with identical electrical specifications but in 28-SSOP packaging (0.209", 5.30mm Width) instead of 28-SOIC. This variant is appropriate for space-constrained PCB layouts.
Temperature-Rated Variants:
MAX213CWI+ and MAX213CWI+T operate across 0°C to 70°C temperature range instead of -40°C to 85°C. These parts are suitable only for applications within the narrower temperature specification.
Frequently Asked Questions (FAQ)
Q: Can I use TRS213IDBR as a direct replacement for MAX213IDWR?
A: TRS213IDBR is electrically equivalent but uses 28-SSOP packaging instead of 28-SOIC. PCB layout modifications are required due to different pin pitch and package dimensions. Verify footprint compatibility before substitution.
Q: What is the difference between MAX213EEWI+ and ADM213EARZ?
A: Both are 4/5 transceiver RS232 ICs in 28-SOIC packaging. MAX213EEWI+ has 500 mV receiver hysteresis and 120Kbps data rate. ADM213EARZ has 650 mV receiver hysteresis and 230kbps data rate. The higher hysteresis in ADM213EARZ may affect noise immunity characteristics in specific applications.
Q: Is HIN213EIBZ compatible with MAX213IDWR applications?
A: HIN213EIBZ maintains all electrical specifications including 500 mV receiver hysteresis and -40°C to 85°C operating temperature. The enhanced data rate (230kbps) is backward compatible. Moisture sensitivity level differs (MSL 3 versus MSL 1), which may impact storage and handling requirements.
Q: Why should I choose a Tape & Reel packaged part over Tube packaging?
A: Tape & Reel packaging is optimized for automated assembly processes and high-volume production. Tube packaging is suitable for lower-volume applications or manual assembly. Selection depends on manufacturing process requirements and order quantities.
Q: Can MAX213CWI+ replace MAX213IDWR in all applications?
A: MAX213CWI+ has a narrower operating temperature range (0°C to 70°C versus -40°C to 85°C). Substitution is valid only for applications operating within this narrower temperature specification.
Q: What does ROHS3 compliance mean for these parts?
A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, and other hazardous materials. All listed substitute parts maintain ROHS3 compliance with the original MAX213IDWR.
