Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX243EPE+ is determined by strict equivalence across the following critical parameters:

• Protocol Compatibility: RS232 full-duplex transceiver architecture
• Functional Configuration: 2/2 driver/receiver configuration
• Electrical Specifications: 4.5V to 5.5V supply voltage range, 200kbps data rate capability, 500mV receiver hysteresis
• Thermal Range: -40°C to 85°C operating temperature
• Physical Package: 16-pin DIP form factor (0.300", 7.62mm pitch)
• Mounting Technology: Through-hole compatible
• Regulatory Compliance: RoHS3 compliance and REACH unaffected status

The MAX232AEPE+ meets all specified parameters and qualifies as a parametric equivalent. Both parts share identical electrical characteristics, thermal specifications, and package dimensions, enabling direct substitution in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

Both the MAX243EPE+ and MAX232AEPE+ maintain active product status with full RoHS3 compliance and REACH unaffected designation. Selection between these parts should be based on inventory availability and procurement lead times, as both components satisfy identical electrical, thermal, and mechanical requirements. The MAX232AEPE+ currently maintains higher inventory levels (1200 pcs) compared to the MAX243EPE+ (1125 pcs), which may influence supply chain decisions. Both parts carry equivalent regulatory certifications (ECCN: EAR99, HTSUS: 8542.39.0001) and moisture sensitivity ratings (MSL 1 - Unlimited), ensuring consistent handling and storage requirements across substitution scenarios.

Frequently Asked Questions (FAQ)

Q: Can MAX232AEPE+ replace MAX243EPE+ in existing circuit designs? A: Yes. Both parts are parametric equivalents with identical RS232 transceiver specifications, electrical ratings, thermal operating ranges, and 16-pin DIP package dimensions.
