Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX232MLP is determined by strict equivalence across the following critical parameters:

• Protocol specification: RS232
• Channel configuration: 2 drivers / 2 receivers
• Receiver hysteresis: 500 mV
• Data rate capability: 120 Kbps minimum
• Supply voltage: 5V
• Package type: 20-LCC (8.9x8.9)
• Operating temperature range: -55°C to 125°C minimum
• Mounting type: Surface Mount

The MAX232MLP/883B variant meets all functional and electrical requirements for direct substitution. This part maintains identical electrical specifications and package configuration while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The MAX232MLP/883B serves as the direct functional equivalent for the obsolete MAX232MLP. Both parts share identical electrical characteristics, channel configuration, and package specifications. The primary distinction is product lifecycle status: MAX232MLP/883B maintains active manufacturing status with established supply chain availability.

Selection between these parts depends on compliance requirements. The original MAX232MLP carries ROHS3 compliance certification. The MAX232MLP/883B is RoHS non-compliant. Applications subject to RoHS regulatory requirements must account for this compliance difference in design validation and procurement decisions.

Frequently Asked Questions (FAQ)

Q: Can MAX232MLP/883B replace MAX232MLP in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all functional parameters: RS232 protocol, 2/2 driver/receiver configuration, 500 mV receiver hysteresis, 120 Kbps data rate, 5V supply voltage, and 20-LCC package. Pin-for-pin compatibility is maintained.

Q: What is the difference between MAX232MLP and MAX232MLP/883B?

A: The parts are functionally equivalent. MAX232MLP/883B is the active production variant with current manufacturing status. MAX232MLP is classified as obsolete. RoHS compliance differs: MAX232MLP is ROHS3 compliant; MAX232MLP/883B is RoHS non-compliant.

Q: Are there package or mounting differences?

A: No. Both parts use identical 20-LCC (8.9x8.9) surface mount packaging. PCB footprints and assembly processes remain unchanged.

Q: Which part should be selected for new designs?

A: MAX232MLP/883B is the appropriate selection for new designs due to active product status and established supply availability. Compliance requirements must be evaluated based on application regulatory scope.

Q: What is the operating temperature range for both parts?

A: Both MAX232MLP and MAX232MLP/883B operate across -55°C to 125°C, supporting industrial and extended temperature applications.
