MAX214CWI Equivalent & Substitute Parts

Part Overview

The MAX214CWI is a full-duplex RS232 transceiver IC manufactured by Analog Devices Inc./Maxim Integrated, configured with 3 drivers and 5 receivers in a 28-SOIC surface mount package. This component is classified as obsolete, which necessitates identification of equivalent substitute parts for ongoing design support and procurement planning. The device operates within the 4.5V to 5.5V supply voltage range and supports data rates up to 116 Kbps, making it suitable for legacy RS232 communication applications requiring full-duplex operation.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX214CWI is determined by strict equivalence across the following critical parameters:

• Protocol and Configuration: RS232 full-duplex transceiver with 3 drivers and 5 receivers
• Electrical Specifications: Supply voltage range 4.5V to 5.5V, data rate 116 Kbps, receiver hysteresis 500 mV
• Physical Package: 28-SOIC surface mount package with identical footprint dimensions (0.295", 7.50mm width)
• Functional Characteristics: Full-duplex operation capability

The MAX214CWI+ meets all these criteria as a parametric equivalent, with the primary distinction being product status and compliance certification level.

Parameter Comparison

Engineering Selection Recommendations

The MAX214CWI+ is the direct parametric equivalent for the obsolete MAX214CWI. Both parts share identical electrical specifications, package geometry, and functional configuration. The primary advantages of selecting MAX214CWI+ are:

• Product Status: Active production status ensures continued availability and supply chain reliability
• Compliance: ROHS3 compliance meets current environmental and regulatory requirements, whereas the original MAX214CWI is RoHS non-compliant
• Packaging: Supplied in tube packaging, facilitating automated assembly processes

Both parts maintain identical pin configuration, electrical performance, and thermal characteristics. The substitution is direct with no circuit modifications required.

Frequently Asked Questions (FAQ)

Q: Can MAX214CWI+ be used as a direct replacement for MAX214CWI?

A: Yes. The MAX214CWI+ is a parametric equivalent with identical electrical specifications, pin configuration, and package dimensions. No circuit modifications are required for substitution.

Q: What is the difference between MAX214CWI and MAX214CWI+?

A: The primary differences are product status (obsolete versus active), RoHS compliance (non-compliant versus ROHS3 compliant), and packaging format (unspecified versus tube). Electrical and functional specifications are identical.

Q: Are the pin configurations identical between these parts?

A: Yes. Both parts use the 28-SOIC package with identical footprint dimensions (0.295", 7.50mm width) and pin assignments.

Q: Does the RoHS3 compliance of MAX214CWI+ affect circuit performance?

A: No. RoHS3 compliance relates to material composition and environmental standards, not electrical performance. The MAX214CWI+ maintains identical electrical specifications and data rate performance.

Q: What supply voltage range is supported?

A: Both parts operate within 4.5V to 5.5V supply voltage range with identical electrical characteristics across this range.

Q: Is the operating temperature range the same?

A: Yes. Both parts operate across 0°C to 70°C with identical thermal specifications.
