Engineering Selection Recommendations

Primary Recommendation for Direct Replacement: MAX207IDWR is the recommended direct substitute for TRS207CDW. Both parts maintain identical electrical specifications (500 mV receiver hysteresis, 120 kbps data rate) and identical package geometry (24-SOIC). MAX207IDWR is manufactured by Texas Instruments, maintaining original manufacturer continuity, and carries Active product status with ROHS3 compliance and MSL 1 rating. The supply voltage range narrows from 4.5V ~ 5.5V to 4.75V ~ 5.25V, and operating temperature extends from 0°C ~ 70°C to -40°C ~ 85°C, both representing enhanced specifications suitable for the original application.

Alternative Substitutes by Application Requirements:

For applications requiring identical supply voltage range (4.5V ~ 5.5V) with extended operating temperature (-40°C ~ 85°C), ADM207ARZ or ADM207ARZ-REEL are suitable. These parts introduce 650 mV receiver hysteresis compared to the original 500 mV specification. ADM207EARZ and ADM207EARZ-REEL offer the same voltage and temperature specifications with increased data rate capability (230 kbps versus 120 kbps).

For applications constrained to original operating temperature range (0°C ~ 70°C), MAX207CWG+, MAX207CWG+T, MAX207ECWG+, and MAX207ECWG+T maintain this specification while providing Active product status and ROHS3 compliance.

All substitute parts are ROHS3 compliant with MSL 1 rating, matching the original part's environmental and regulatory classification.

Frequently Asked Questions (FAQ)

Q: Can ADM207 series parts directly replace TRS207CDW? A: ADM207ARZ and ADM207ARZ-REEL are functionally compatible substitutes. Both maintain the 5/3 driver/receiver configuration, RS232 protocol, full-duplex operation, and 24-SOIC package. The receiver hysteresis increases from 500 mV to 650 mV. Supply voltage range remains 4.5V ~ 5.5V, and operating temperature extends to -40°C ~ 85°C. These parts are suitable for applications where the increased hysteresis specification does not conflict with signal integrity requirements.

Q: What is the difference between MAX207CWG+ and MAX207EEWG+? A: Both parts share identical electrical specifications (500 mV hysteresis, 120 kbps data rate, 4.75V ~ 5.25V supply) and 24-SOIC packaging. The primary difference is operating temperature range: MAX207CWG+ operates 0°C ~ 70°C, while MAX207EEWG+ extends to -40°C ~ 85°C. Selection depends on the target application's thermal environment.

Q: Does packaging type (Tube vs. Tape & Reel) affect electrical compatibility? A: No. Packaging type (Tube or Tape & Reel) is a logistics and handling specification only. Electrical performance, pin configuration, and functional characteristics remain identical between parts with the same base part number. Selection is based on procurement and assembly process requirements.

Q: Why does TRS207CDW show as Obsolete? A: TRS207CDW is classified as obsolete by Texas Instruments. All listed substitute parts carry Active product status, ensuring long-term availability and manufacturing support. Transition to an active equivalent part is recommended for new designs and ongoing production.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All substitute parts listed maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original TRS207CDW environmental and regulatory classification.

Q: Can MAX207IDWR be used in applications originally designed for TRS207CDW? A: Yes. MAX207IDWR is the recommended direct substitute. It maintains identical receiver hysteresis (500 mV), data rate (120 kbps), and package configuration (24-SOIC). The supply voltage range narrows slightly (4.75V ~ 5.25V versus 4.5V ~ 5.5V), and operating temperature extends to -40°C ~ 85°C. These changes represent enhanced specifications suitable for the original application scope.
