Substitute Part Grouping Explanation

Substitution of the SP310ACP-L is determined by strict equivalence across the following critical parameters:

• Protocol Compatibility: RS232 full duplex transceiver functionality
• Channel Configuration: 2 drivers and 2 receivers (2/2 architecture)
• Electrical Specifications: 4.5V to 5.5V supply voltage range, 500 mV receiver hysteresis, minimum 240 kbps data rate capability
• Physical Form Factor: 18-pin DIP package with 0.300" (7.62mm) pitch
• Thermal Range: 0°C to 70°C operating temperature
• Mounting Technology: Through-hole assembly compatibility

The MAX222CPN+ from Analog Devices Inc./Maxim Integrated meets all substitution criteria, providing functional and mechanical equivalence while offering active product status and improved availability.

Engineering Selection Recommendations

The MAX222CPN+ is the primary substitute for the obsolete SP310ACP-L. Selection is based on the following factors:

Product Status: The MAX222CPN+ maintains active product status with Analog Devices Inc./Maxim Integrated, ensuring long-term availability and supply chain continuity compared to the obsolete SP310ACP-L.

Regulatory Compliance: Both components share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications, maintaining compliance with export control and tariff requirements.

RoHS Compliance: The MAX222CPN+ is ROHS3 compliant, meeting current environmental and hazardous substance restrictions applicable to electronic components.

Electrical Equivalence: The MAX222CPN+ exceeds the minimum data rate specification of the SP310ACP-L (250 kbps versus 240 kbps), while maintaining all other electrical parameters within identical ranges.

Physical Compatibility: Identical 18-PDIP package specifications ensure direct pin-for-pin replacement without PCB redesign or mechanical modifications.

Frequently Asked Questions (FAQ)

Q: Can the MAX222CPN+ be used as a direct replacement for the SP310ACP-L?

A: Yes. The MAX222CPN+ provides pin-for-pin compatibility and electrical equivalence across all critical parameters: RS232 protocol, 2/2 driver/receiver configuration, full duplex operation, 500 mV receiver hysteresis, 4.5V to 5.5V supply voltage, 0°C to 70°C operating temperature, and 18-DIP package form factor.

Q: What is the difference in data rate between these components?

A: The SP310ACP-L operates at 240 kbps, while the MAX222CPN+ operates at 250 kbps. This difference represents a performance improvement and does not affect backward compatibility in applications designed for the SP310ACP-L.

Q: Are there any package or mounting differences?

A: No. Both components use identical 18-pin DIP packages with 0.300" (7.62mm) pitch and through-hole mounting technology, enabling direct PCB substitution without layout modifications.

Q: What compliance certifications apply to the MAX222CPN+?

A: The MAX222CPN+ is ROHS3 compliant and REACH unaffected. Both components share EAR99 export classification and 8542.39.0001 HTSUS tariff code.

Q: Why is the SP310ACP-L obsolete?

A: The SP310ACP-L has been discontinued by MaxLinear, Inc. The MAX222CPN+ from Analog Devices Inc./Maxim Integrated represents the active equivalent product for new designs and replacement applications.
