Receiver Hysteresis: 500 mV
Voltage - Supply: 4.5V ~ 5.5V
Package / Case: 28-SOIC (0.295", 7.50mm Width)
Mounting Type: Surface Mount
RoHS Status: ROHS3 Compliant

Allowable Variations:

Data Rate: 120 Kbps or higher (backward compatible)
Operating Temperature: Extended ranges acceptable (0°C ~ 70°C or -40°C ~ 85°C)
Product Status: Active or Last Time Buy preferred over Obsolete
Moisture Sensitivity Level: MSL 1 or MSL 3 acceptable

Substitute parts are grouped into three categories: Upgrade options with extended temperature ranges and active product status, manufacturer-recommended alternatives with enhanced specifications, and parametric equivalents with identical core electrical characteristics.

Engineering Selection Recommendations

Upgrade Path (Extended Temperature Range): MAX213EEWI+ and MAX213EWI+ are active products from Analog Devices Inc./Maxim Integrated offering extended operating temperature range (-40°C ~ 85°C) compared to the TRS213CDW (0°C ~ 70°C). These parts maintain identical electrical specifications and 28-SOIC packaging, providing direct substitution with improved environmental performance for applications requiring wider temperature operation.

Manufacturer-Recommended Alternatives: HIN213EIBZ from Renesas Electronics Corporation is an active product with enhanced data rate capability (230 Kbps versus 120 Kbps) and extended temperature range (-40°C ~ 85°C). This part meets all core electrical and mechanical requirements with superior performance margins. MAX213CWI+T from Analog Devices Inc./Maxim Integrated is supplied in Tape & Reel packaging with the highest inventory availability (2300 pcs), maintaining identical operating temperature and data rate specifications as the original TRS213CDW.

Parametric Equivalents (Identical Specifications): MAX213CWI+, MAX213ECWI+, and MAX211ECWI+ from Analog Devices Inc./Maxim Integrated are active products with identical electrical parameters and operating temperature range (0°C ~ 70°C) to the TRS213CDW. These parts provide direct functional replacement with confirmed active product status and ROHS3 compliance.

Compliance Considerations: All substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the original TRS213CDW certification requirements. Moisture sensitivity levels range from MSL 1 (unlimited) to MSL 3 (168 hours), both acceptable for standard handling and storage protocols.
