MAX3248ECAI Equivalent & Substitute Parts

Part Overview

The MAX3248ECAI is a full-duplex RS232 transceiver with 5 drivers and 3 receivers, manufactured by Analog Devices Inc./Maxim Integrated. This 28-SSOP surface-mount device operates across a 3V to 5.5V supply range and supports data rates up to 250kbps. The part is classified as obsolete, making identification of compatible substitutes essential for ongoing system support and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX3248ECAI is determined by strict equivalence across the following critical parameters:

• Protocol specification: RS232
• Driver/Receiver configuration: 5 drivers / 3 receivers
• Duplex mode: Full
• Data rate capability: 250kbps minimum
• Supply voltage range: 3V ~ 5.5V
• Operating temperature range: 0°C ~ 70°C
• Package type: 28-SSOP with identical physical dimensions (0.209", 5.30mm Width)
• Receiver hysteresis: 600 mV

The MAX3238ECAI+ meets all these parameters and qualifies as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The MAX3238ECAI+ is a direct parametric equivalent to the MAX3248ECAI across all functional and physical specifications. The primary distinction is product lifecycle status: the MAX3248ECAI is obsolete while the MAX3238ECAI+ is active production. Additionally, the MAX3238ECAI+ carries ROHS3 compliance certification, whereas the MAX3248ECAI is non-compliant. Both parts share identical electrical characteristics, pin configuration, and package geometry, enabling direct substitution in applications requiring RS232 transceiver functionality with 5/3 driver/receiver configuration.

Frequently Asked Questions (FAQ)

Q: Can the MAX3238ECAI+ directly replace the MAX3248ECAI in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters. The 28-SSOP package dimensions, pin configuration, and electrical performance are identical.

Q: What is the primary reason to substitute the MAX3248ECAI?

A: The MAX3248ECAI is classified as obsolete. The MAX3238ECAI+ is the active production equivalent, ensuring long-term availability and supply chain continuity.

Q: Are there compliance differences between these parts?

A: Yes. The MAX3238ECAI+ is ROHS3 compliant, while the MAX3248ECAI is RoHS non-compliant. Both are REACH Unaffected and carry EAR99 ECCN classification.

Q: Do the parts have identical pinouts?

A: Yes. Both use the 28-SSOP package with identical physical dimensions (0.209", 5.30mm Width) and are pin-compatible.

Q: Are there any electrical performance differences?

A: No. Both parts operate at identical supply voltages (3V ~ 5.5V), support the same data rate (250kbps), maintain 600 mV receiver hysteresis, and operate across the same temperature range (0°C ~ 70°C).
