MAX202CUE RS232 Transceiver Equivalent & Substitute Parts

Part Overview

The MAX202CUE is a 2/2 full-duplex RS232 transceiver manufactured by Analog Devices Inc./Maxim Integrated, housed in a 16-TSSOP surface mount package. This component interfaces between TTL/CMOS logic levels and RS232 signal levels, supporting data rates up to 120 Kbps with a 500 mV receiver hysteresis specification. The MAX202CUE is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support, design updates, and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX202CUE is determined by strict equivalence across the following critical parameters:

• Protocol Compatibility: RS232 standard compliance
• Channel Configuration: 2 drivers and 2 receivers (2/2 full-duplex)
• Electrical Specifications: Supply voltage range (4.5V ~ 5.5V), data rate (120 Kbps), receiver hysteresis (500 mV)
• Package Compatibility: 16-TSSOP surface mount package with identical pinout and mechanical dimensions (0.173", 4.40mm Width)
• Operating Temperature Range: 0°C ~ 70°C

All identified substitute parts maintain these parameters without deviation. Substitution is valid only when all electrical and mechanical specifications align precisely with the original component.

Engineering Selection Recommendations

MAX202CUE+ (Recommended Primary Substitute)

The MAX202CUE+ is the direct functional equivalent with active product status. It maintains identical electrical and mechanical specifications while offering ROHS3 compliance, addressing regulatory requirements for new designs and procurement. This part is sourced from the original manufacturer (Analog Devices Inc./Maxim Integrated) and represents the most direct replacement path.

MAX202ECUE+ (Alternative Equivalent)

The MAX202ECUE+ provides equivalent functionality with active product status and ROHS3 compliance. As an Analog Devices Inc./Maxim Integrated product, it maintains full parameter alignment with the original MAX202CUE. Higher inventory availability (1900 Pcs) may support extended production runs.

MAX202CPW (Secondary Option)

The MAX202CPW is a parametric equivalent sourced from Texas Instruments. While maintaining all critical electrical and mechanical specifications, this part carries obsolete product status. ROHS3 compliance is confirmed. Selection of this part should be evaluated against long-term availability constraints.

Frequently Asked Questions (FAQ)

Q: Can MAX202CUE+ be used as a direct replacement for MAX202CUE?

A: Yes. The MAX202CUE+ maintains identical electrical specifications (RS232 protocol, 2/2 configuration, 4.5V ~ 5.5V supply, 120 Kbps data rate, 500 mV receiver hysteresis) and package geometry (16-TSSOP surface mount). The primary difference is active product status and ROHS3 compliance.

Q: What is the difference between MAX202CUE+ and MAX202ECUE+?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. The difference lies in the part number designation (CUE+ versus ECUE+), which may reflect internal manufacturing or qualification variations within Analog Devices Inc./Maxim Integrated. Both maintain active product status and ROHS3 compliance.

Q: Is the MAX202CPW from Texas Instruments compatible?

A: Yes, the MAX202CPW is a parametric equivalent meeting all electrical and mechanical requirements. However, it carries obsolete product status. Compatibility is confirmed for direct pin-for-pin replacement in 16-TSSOP surface mount applications.

Q: Are there packaging differences between these substitutes?

A: All substitute parts use identical 16-TSSOP surface mount packaging (0.173", 4.40mm Width). Pinout and mechanical dimensions are equivalent, enabling direct PCB-level substitution without layout modifications.

Q: What compliance considerations apply to substitution?

A: The original MAX202CUE is RoHS non-compliant. All recommended substitutes (MAX202CUE+, MAX202ECUE+, MAX202CPW) are ROHS3 compliant. For applications subject to RoHS directives, substitution with compliant alternatives is required. All parts maintain REACH Unaffected status.

Q: Can these parts be used interchangeably in production?

A: Yes, within the constraints of product status. MAX202CUE+ and MAX202ECUE+ are recommended for new production due to active status. MAX202CPW may be used for legacy system support but should be evaluated for long-term availability.
