MAX561CWI Equivalent & Substitute Parts

Part Overview

The MAX561CWI is a 4/5 transceiver interface circuit manufactured by Analog Devices Inc./Maxim Integrated, designed for RS562 serial communication applications. This component operates as a full-duplex transceiver in a 28-SOIC surface mount package. The MAX561CWI is currently classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing system support, design updates, and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX561CWI is determined by strict alignment of the following critical parameters:

• Package / Case: 28-SOIC (0.295", 7.50mm Width) — mechanical and electrical compatibility
• Number of Drivers/Receivers: 4/5 — functional channel count
• Duplex Mode: Full — bidirectional communication capability
• Data Rate: 116 Kbps — maximum signaling speed
• Voltage - Supply: 3V ~ 3.6V — power supply compatibility
• Operating Temperature: 0°C ~ 70°C — thermal operating range
• Receiver Hysteresis: 300 mV — input threshold specification
• Mounting Type: Surface Mount — PCB assembly compatibility

All substitute parts listed maintain these core electrical and mechanical parameters. Protocol differences (RS562 vs. RS232) do not prevent functional substitution when all other parameters align, as both protocols operate within the same electrical framework at the specified data rates and voltage levels.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain full electrical and mechanical compatibility with the MAX561CWI across all critical parameters. Selection among these alternatives should be based on the following factors:

Product Status: The MAX561CWI is obsolete. All substitute parts (MAX560CWI+, ADM561JRZ-REEL, ADM560JRZ, ADM561JRZ) are classified as active products, ensuring long-term availability and supply chain stability.

Regulatory Compliance: The MAX561CWI is RoHS non-compliant. All substitute parts are ROHS3 compliant, meeting current environmental and regulatory requirements for new designs and procurement.

Packaging Format: Selection between tube and tape & reel packaging depends on assembly volume and handling requirements. ADM561JRZ-REEL is supplied in tape & reel format, suitable for high-volume automated assembly. MAX560CWI+, ADM560JRZ, and ADM561JRZ are supplied in tube packaging, appropriate for lower-volume or manual assembly operations.

Inventory Availability: ADM561JRZ offers the highest inventory level (36,300 pcs), followed by ADM560JRZ (3,839 pcs), MAX560CWI+ (707 pcs), and ADM561JRZ-REEL (864 pcs).

Frequently Asked Questions (FAQ)

Q: Can MAX560CWI+ directly replace MAX561CWI in existing designs?

A: Yes. MAX560CWI+ maintains all critical electrical parameters (4/5 drivers/receivers, full-duplex operation, 116 Kbps data rate, 3V ~ 3.6V supply, 0°C ~ 70°C operating range, 300 mV receiver hysteresis) and uses the identical 28-SOIC package. The primary advantage is active product status and ROHS3 compliance.

Q: What is the difference between ADM561JRZ and ADM561JRZ-REEL?

A: Both parts are electrically and mechanically identical. The difference is packaging format: ADM561JRZ is supplied in tube packaging, while ADM561JRZ-REEL is supplied in tape & reel format. Selection depends on assembly volume and automation requirements.

Q: Are there protocol differences between RS562 and RS232 variants?

A: The MAX561CWI operates on RS562 protocol, while ADM560JRZ, ADM561JRZ, and ADM561JRZ-REEL operate on RS232 protocol. Both protocols function within the same electrical framework at the specified data rates and voltage levels. All parts maintain identical electrical parameters and 28-SOIC package compatibility.

Q: Is the MAX561CWI still available for procurement?

A: The MAX561CWI is classified as obsolete. Current inventory exists (2,352 pcs), but long-term availability is not guaranteed. Migration to active substitute parts is recommended for new designs and ongoing system support.

Q: What is the Moisture Sensitivity Level (MSL) significance?

A: All parts, including the MAX561CWI and all substitutes, carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These components can be stored and handled without special moisture control measures.
