MAX230CPP+ Equivalent & Substitute Parts Reference

Part Overview

The MAX230CPP+ is a 5/0 RS232 driver IC manufactured by Analog Devices Inc./Maxim Integrated, housed in a 20-pin DIP package. This component functions as an interface driver for RS232 serial communication applications, supporting data rates up to 250kbps with a supply voltage range of 4.5V to 5.5V. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance, legacy design support, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX230CPP+ is determined by strict alignment with the following critical parameters:

• Protocol Compatibility: RS232 interface standard
• Driver/Receiver Configuration: 5 drivers and 0 receivers
• Data Rate Capability: Minimum 250kbps support
• Supply Voltage Range: 4.5V to 5.5V operation
• Package Type: 20-pin DIP form factor with 0.300" (7.62mm) pitch
• Mounting Technology: Through-hole PCB mounting
• Electrical Specifications: Operating temperature range 0°C to 70°C

Only components matching all these parameters qualify as direct substitutes. The MAX230CPP+ itself represents the only part meeting these exact specifications within the provided dataset.

Parameter Comparison

Engineering Selection Recommendations

The MAX230CPP+ is classified as obsolete. When sourcing this component, the following factors apply:

• Compliance Status: ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards
• Availability: 885 pieces currently in stock as new original inventory
• Packaging: Supplied in tube packaging, suitable for automated assembly or manual placement
• Certification: EAR99 classification; HTSUS code 8542.39.0001

Selection of equivalent parts must prioritize exact parameter matching across protocol, driver/receiver count, data rate, supply voltage, package geometry, and mounting technology. No parameter deviation is acceptable for direct substitution in RS232 driver applications.

Frequently Asked Questions (FAQ)

Q: What makes a part a valid substitute for the MAX230CPP+?

A: A valid substitute must match all critical parameters: RS232 protocol, 5 drivers/0 receivers configuration, 250kbps minimum data rate, 4.5V–5.5V supply voltage, 20-pin DIP package with 0.300" pitch, through-hole mounting, and 0°C–70°C operating temperature range.

Q: Is the MAX230CPP+ still in production?

A: No. The MAX230CPP+ is classified as obsolete. However, 885 pieces of new original stock are currently available.

Q: Can I use a different package type as a substitute?

A: No. The 20-DIP (0.300", 7.62mm) package is a critical parameter. Different package types (such as SOIC or QFP variants) are not interchangeable without PCB redesign and are not considered direct substitutes.

Q: What is the significance of the 5/0 driver/receiver configuration?

A: The 5/0 designation indicates 5 RS232 drivers and 0 receivers. This configuration is specific to transmit-only applications. Substitutes must maintain this exact ratio; parts with different driver/receiver counts are not compatible.

Q: Does the RoHS3 compliance status affect substitution?

A: RoHS3 compliance is a regulatory requirement for current manufacturing. When sourcing substitutes, ensure compliance status matches or exceeds the original part's certification level.

Q: What is Moisture Sensitivity Level (MSL) 1, and why does it matter?

A: MSL 1 indicates unlimited shelf life without moisture-related degradation. This is the most favorable rating and simplifies storage and handling requirements compared to higher MSL ratings.
