ICL3217CA-T Equivalent & Substitute Parts

Part Overview

The ICL3217CA-T is a full-duplex RS232 transceiver manufactured by Renesas Electronics Corporation, configured with 5 drivers and 3 receivers in a 24-SSOP surface mount package. This component operates across a 3V to 5.5V supply voltage range and supports data rates up to 250kbps, making it suitable for legacy serial communication applications requiring bidirectional signal conversion.

The ICL3217CA-T is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support long-term product maintenance where original components are no longer in production.

Substitute Part Grouping Explanation

Substitution of the ICL3217CA-T is determined by strict equivalence across the following critical parameters:

• Protocol: RS232 full-duplex transceiver
• Driver/Receiver Configuration: 5 drivers and 3 receivers
• Package Type: 24-SSOP surface mount
• Electrical Specifications: 3V to 5.5V supply voltage, 250kbps data rate, 300 mV receiver hysteresis
• Operating Temperature Range: 0°C to 70°C

The ICL3207ECAZ-T meets all these criteria and is classified as a parametric equivalent. This substitute maintains identical electrical performance and physical form factor, enabling direct replacement in existing designs.

Parameter Comparison

Engineering Selection Recommendations

The ICL3207ECAZ-T is the direct parametric equivalent for the obsolete ICL3217CA-T. Both components share identical electrical specifications, driver/receiver configuration, and physical packaging, ensuring functional compatibility in existing circuit designs.

The ICL3207ECAZ-T offers the following advantages:

• Active product status ensures ongoing availability and supply chain support
• ROHS3 compliance aligns with current environmental and regulatory standards
• Equivalent electrical performance across all specified parameters

The MSL rating difference (1 versus 3) reflects different moisture sensitivity classifications. The ICL3207ECAZ-T requires controlled storage conditions (168 hours at specified humidity levels), whereas the ICL3217CA-T has unlimited moisture tolerance. This difference does not affect electrical performance but impacts handling and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can the ICL3207ECAZ-T directly replace the ICL3217CA-T without circuit modifications?

A: Yes. Both components are electrically and mechanically equivalent. The 24-SSOP package, pin configuration, supply voltage range, data rate, and receiver hysteresis are identical. No circuit redesign is required.

Q: What is the significance of the RoHS compliance difference?

A: The ICL3217CA-T is RoHS non-compliant, while the ICL3207ECAZ-T is ROHS3 compliant. This affects material composition and environmental impact but does not alter electrical performance or functionality. ROHS3 compliance is required for new designs and applications subject to environmental regulations.

Q: Does the MSL rating difference affect substitution?

A: The MSL rating difference reflects storage and handling requirements, not electrical performance. The ICL3207ECAZ-T (MSL 3) requires controlled storage at specified humidity levels for up to 168 hours before soldering. The ICL3217CA-T (MSL 1) has no moisture sensitivity restrictions. Both components perform identically once installed in the circuit.

Q: Are there any pin-to-pin differences between these parts?

A: No. Both components use the 24-SSOP package with identical pin assignments and electrical characteristics. Pin-to-pin compatibility is complete.

Q: Why is the ICL3217CA-T classified as obsolete?

A: The ICL3217CA-T has been discontinued by the manufacturer. The ICL3207ECAZ-T is the active replacement, offering equivalent functionality with improved compliance status and ongoing supply availability.
