MAX207CDWR Equivalent & Substitute Parts

Part Overview

The MAX207CDWR is a 5/3 full-duplex RS232 transceiver manufactured by Texas Instruments in 24-SOIC surface mount packaging. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new designs. The MAX207CDWR operates within a supply voltage range of 4.75V to 5.25V and supports data rates up to 120Kbps with a receiver hysteresis of 500mV. Substitute parts must maintain functional equivalence in transceiver topology, RS232 protocol compliance, driver/receiver configuration, and physical packaging while accommodating variations in operating temperature ranges and supply voltage specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX207CDWR is determined by the following critical parameters:

Functional Requirements:

• RS232 protocol compliance
• 5/3 driver/receiver configuration
• Full-duplex operation
• 24-SOIC package footprint compatibility

Electrical Compatibility:

• Data rate support (minimum 120Kbps)
• Receiver hysteresis characteristics
• Supply voltage range overlap or compatibility
• Operating temperature range suitability for application

Physical & Compliance Requirements:

• 24-SOIC surface mount package
• ROHS3 compliance
• MSL rating of 1 or better

Substitute parts are grouped into two categories based on operating temperature range and supply voltage specifications:

Category A - Direct Replacements (Identical Operating Conditions): MAX207IDWR, MAX207CWG+, MAX207ECWG+, MAX207EEWG+

Category B - Extended Operating Range (Broader Temperature/Voltage Specifications): ADM207ARZ-REEL, ADM207EARZ

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute - MAX207IDWR: The MAX207IDWR is the recommended substitute for the obsolete MAX207CDWR. Both parts are manufactured by Texas Instruments, share identical electrical specifications (120Kbps data rate, 500mV receiver hysteresis, 4.75V to 5.25V supply voltage), and use the same 24-SOIC package. The MAX207IDWR extends the operating temperature range to -40°C to 85°C, providing broader environmental compatibility. Product status is active with established supply availability.

Alternative Substitute - MAX207EEWG+: The MAX207EEWG+ offers the same electrical performance as MAX207CDWR with extended operating temperature range (-40°C to 85°C). This part maintains identical receiver hysteresis and data rate specifications. Packaging differs in form factor (tube versus tape & reel) but maintains 24-SOIC footprint compatibility. Product status is active.

Extended Range Substitutes - ADM207ARZ-REEL and ADM207EARZ: Analog Devices ADM207 series parts provide broader supply voltage tolerance (4.5V to 5.5V) and extended operating temperature range (-40°C to 85°C). The ADM207EARZ additionally supports higher data rates (230Kbps). Receiver hysteresis is specified at 650mV, which remains within acceptable RS232 transceiver specifications. Both parts maintain 24-SOIC package compatibility and ROHS3 compliance. These substitutes are suitable for applications requiring enhanced environmental performance.

Packaging Consideration: MAX207CDWR is supplied in tape & reel packaging. Substitutes MAX207CWG+ and MAX207ECWG+ are supplied in tube packaging. MAX207IDWR and ADM207ARZ-REEL maintain tape & reel packaging. Verify packaging requirements for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can MAX207IDWR directly replace MAX207CDWR in existing designs? A: Yes. MAX207IDWR maintains identical electrical specifications and 24-SOIC package footprint. The extended operating temperature range (-40°C to 85°C versus 0°C to 70°C) provides additional environmental margin without affecting circuit operation within the original temperature specification.

Q: What is the difference between MAX207EEWG+ and MAX207ECWG+? A: Both parts share identical electrical specifications (120Kbps, 500mV hysteresis, 4.75V to 5.25V supply). MAX207EEWG+ operates from -40°C to 85°C, while MAX207ECWG+ operates from 0°C to 70°C. Both use tube packaging. Selection depends on application temperature requirements.

Q: Are ADM207 parts compatible with MAX207 designs? A: ADM207ARZ-REEL and ADM207EARZ maintain the same 5/3 RS232 transceiver topology and 24-SOIC package. Supply voltage range is broader (4.5V to 5.5V), and operating temperature extends to -40°C to 85°C. Receiver hysteresis is 650mV versus 500mV. These differences remain within RS232 specification tolerances and do not prevent functional substitution.

Q: Why does ADM207EARZ support 230Kbps while others support 120Kbps? A: ADM207EARZ is specified for higher data rate operation. This enhanced capability does not prevent use in 120Kbps applications. The part remains fully compatible with lower data rate requirements.

Q: Does packaging type (tape & reel versus tube) affect electrical performance? A: No. Packaging type affects only handling, storage, and assembly processes. Electrical performance and functional characteristics remain identical between tape & reel and tube packaging variants of the same part number.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL rating of 1 (unlimited moisture sensitivity level), matching the original MAX207CDWR specifications.
