CPC5610A Equivalent & Substitute Parts

Part Overview

The CPC5610A is a Telecom Interface IC implementing Data Access Arrangement (DAA) functionality in a 32-SOIC surface mount package. Manufactured by IXYS Integrated Circuits Division as part of the LITELINK® II series, this component is classified as obsolete. Due to its obsolete status and limited availability relative to newer alternatives, identifying functionally equivalent substitute parts is essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CPC5610A is determined by the following critical parameters:

• Package Compatibility: 32-SOIC (0.295", 7.50mm Width) — physical and electrical pin compatibility
• Functional Equivalence: Data Access Arrangement (DAA) interface implementation
• Supply Voltage Range: 3V ~ 5.5V — operational voltage envelope
• Mounting Type: Surface Mount — PCB assembly compatibility
• Thermal Operating Range: Minimum 0°C ~ 85°C (substitute may exceed this range)
• Power Dissipation: 1 W maximum
• Moisture Sensitivity: MSL 3 (168 Hours) — handling and storage requirements

The CPC5620ATR qualifies as a direct substitute based on identical package, function, voltage range, mounting type, and power specifications. The CPC5620ATR operates within an extended temperature range (-40°C ~ 85°C) and demonstrates improved supply current efficiency (9mA vs. 10mA), while maintaining full compatibility with the CPC5610A electrical and mechanical interface requirements.

Parameter Comparison

Engineering Selection Recommendations

The CPC5620ATR serves as the direct substitute for the CPC5610A based on electrical and mechanical parameter equivalence. Both components are classified as obsolete products, indicating end-of-life status from the manufacturer. Selection between these parts should be based on:

• Inventory Availability: CPC5620ATR demonstrates higher stock levels (10,400 Pcs) compared to CPC5610A (1,812 Pcs)
• Temperature Range Extension: CPC5620ATR supports -40°C ~ 85°C operation, providing broader thermal coverage than the CPC5610A specification of 0°C ~ 85°C
• Supply Current Efficiency: CPC5620ATR operates at 9mA supply current versus 10mA for CPC5610A, resulting in reduced power consumption
• Packaging Format: CPC5620ATR is supplied in Tape & Reel (TR) format, suitable for automated assembly processes
• Compliance Status: Both components maintain REACH Unaffected and EAR99 ECCN classifications

Frequently Asked Questions (FAQ)

Q: Can CPC5620ATR be used as a direct replacement for CPC5610A in existing designs?

A: Yes. The CPC5620ATR maintains identical package geometry (32-SOIC), pin configuration, supply voltage range (3V ~ 5.5V), and DAA functional implementation. Pin-for-pin compatibility is confirmed across all electrical and mechanical interfaces.

Q: What are the differences between CPC5610A and CPC5620ATR?

A: The primary differences are: (1) CPC5620ATR operates across an extended temperature range (-40°C to 85°C versus 0°C to 85°C); (2) CPC5620ATR consumes 9mA supply current compared to 10mA; (3) CPC5620ATR is supplied in Tape & Reel packaging; (4) CPC5620ATR belongs to the LITELINK® III series versus LITELINK® II for CPC5610A.

Q: Are there any compatibility concerns when substituting CPC5620ATR for CPC5610A?

A: No compatibility concerns exist for applications operating within the 0°C ~ 85°C temperature range. Applications requiring operation below 0°C benefit from the extended lower temperature limit of CPC5620ATR. Both components share identical MSL 3 moisture sensitivity classification and handling requirements.

Q: What is the significance of the 32-SOIC package specification?

A: The 32-SOIC (0.295", 7.50mm Width) package defines the physical footprint, pin count, and spacing for PCB assembly. Both CPC5610A and CPC5620ATR utilize this identical package specification, ensuring mechanical and electrical compatibility without PCB redesign.

Q: Why are both parts classified as obsolete?

A: Obsolete classification indicates that the manufacturer has discontinued production and support for these components. Substitute identification becomes necessary for system maintenance, repair, and legacy design support. Inventory availability from authorized distributors may be limited.
