Substitute Part Grouping Explanation
Substitution of the TRS202CDG4 is determined by strict equivalence across the following critical parameters:
Mandatory Matching Parameters:
- Protocol: RS232
- Number of Drivers/Receivers: 2/2
- Duplex: Full
- Voltage - Supply: 4.5V ~ 5.5V
- Package / Case: 16-SOIC (0.154", 3.90mm Width)
- Mounting Type: Surface Mount
Allowable Variation Parameters:
- Receiver Hysteresis: 500 mV (baseline) to 650 mV (acceptable for RS232 applications)
- Data Rate: 120 kbps (baseline) to 230 kbps (backward compatible)
- Operating Temperature: 0°C ~ 70°C (baseline) to -40°C ~ 85°C (extended range acceptable)
- Product Status: Obsolete to Active (Active status preferred for new designs)
Substitute parts are grouped into three categories: Direct Manufacturer Equivalents (identical packaging and specifications), Parametric Equivalents (matching core electrical parameters with allowable variations), and Manufacturer-Recommended Upgrades (active production alternatives with enhanced specifications).

Engineering Selection Recommendations
Direct Manufacturer Equivalents (Identical Specifications): TRS202ECDR, MAX202CD, MAX232DG4, and TRS202ECD are parametric equivalents of the TRS202CDG4 with identical electrical specifications. All remain classified as obsolete products. Selection among these should be based on packaging availability and inventory status. TRS202ECDR offers Cut Tape & Digi-Reel packaging with 1422 units in stock, while MAX202CD in Tube packaging has significantly higher inventory at 236,745 units.
Active Production Alternatives (Recommended for New Designs): MAX202ECSE+T and MAX202EESE+T are active production parts manufactured by Analog Devices Inc./Maxim Integrated. Both maintain identical electrical specifications to the TRS202CDG4 with extended operating temperature range (-40°C ~ 85°C). MAX202EESE+T offers the highest inventory availability at 27,498 units in Cut Tape & Digi-Reel packaging and is suitable for designs requiring extended temperature operation.

Enhanced specifications (650 mV receiver hysteresis, 230 kbps data rate) are backward compatible and do not require design modifications.
Q: What packaging options are available for substitutes? A: Substitute parts are available in three packaging formats: Tube (MAX202CD, MAX232DG4, TRS202ECD, MAX202EESE+, ADM202EARNZ), Cut Tape & Digi-Reel (TRS202ECDR, MAX202ECSE+T, MAX202EESE+T, ADM202EARNZ-REEL, ADM202EARNZ-REEL7). Selection should align with production assembly requirements and inventory management practices.
Q: Which substitute offers the best inventory availability? A: ADM202EARNZ-REEL7 provides the highest inventory at 50,300 units, followed by MAX202CD at 236,745 units. For active production parts, MAX202EESE+T offers 27,498 units in Cut Tape & Digi-Reel packaging.
Q: Are all substitutes RoHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL Level 1 rating, consistent with the original TRS202CDG4 specifications.
