CPC5604A Equivalent & Substitute Parts

Part Overview

The CPC5604A is a Telecom Interface IC implementing Data Access Arrangement (DAA) functionality in a 32-SOIC surface mount package. Manufactured by IXYS Integrated Circuits Division under the LITELINK® series, this component is classified as obsolete. Due to its discontinued status, identifying functionally equivalent substitute parts is essential for system redesign, legacy product support, and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CPC5604A is determined by the following critical parameters:

Package Compatibility: The 32-SOIC (0.295", 7.50mm Width) surface mount package is the primary mechanical constraint. Substitute parts must use identical package geometry to ensure PCB layout compatibility without redesign.

Functional Equivalence: All candidates must implement Data Access Arrangement (DAA) functionality within the Telecom Interface category.

Electrical Operating Range: The substitute must accommodate the original supply voltage range (4.75V ~ 5.25V) and current requirements (15mA maximum). Parts with wider voltage ranges or lower current specifications are acceptable if they encompass the original operating envelope.

Temperature Range: The operating temperature range (-20°C ~ 85°C) establishes the thermal performance requirement. Substitutes with equal or extended temperature ranges are acceptable.

Regulatory Compliance: REACH Unaffected status and EAR99 ECCN classification must be maintained.

The CPC5620ATR meets all substitution criteria and is identified as the direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The CPC5620ATR is the identified substitute for the CPC5604A based on functional equivalence and package compatibility. Both components are obsolete products from the same manufacturer, indicating they represent successive generations within the LITELINK® DAA product line.

The CPC5620ATR demonstrates improved electrical characteristics: the supply voltage range (3V ~ 5.5V) encompasses the original specification (4.75V ~ 5.25V), and the reduced current requirement (9mA versus 15mA) indicates enhanced efficiency. The extended operating temperature range (-40°C ~ 85°C) provides broader thermal coverage.

Both parts maintain identical regulatory compliance (REACH Unaffected, EAR99 classification) and package geometry, eliminating redesign requirements at the PCB level. The CPC5620ATR is available in Tape & Reel packaging with RoHS3 compliance, supporting modern manufacturing workflows.

Frequently Asked Questions (FAQ)

Q: Can the CPC5620ATR be used as a direct replacement for the CPC5604A?

A: Yes. Both components share the 32-SOIC package geometry, identical pin count, and equivalent DAA functionality. The CPC5620ATR operates within the voltage and current envelope of the original specification and requires no PCB layout modifications.

Q: What are the key differences between these parts?

A: The CPC5620ATR features a wider supply voltage range (3V ~ 5.5V versus 4.75V ~ 5.25V), lower supply current (9mA versus 15mA), and an extended operating temperature range (-40°C ~ 85°C versus -20°C ~ 85°C). These represent performance improvements in the successor generation.

Q: Are there any packaging differences?

A: Both parts use the 32-SOIC (0.295", 7.50mm Width) surface mount package. The CPC5620ATR is supplied in Tape & Reel format with MSL 3 (168 Hours) rating, compared to the CPC5604A's MSL 6 (Time on Label) rating. This indicates improved moisture handling in the substitute part.

Q: What is the regulatory status of the CPC5620ATR?

A: The CPC5620ATR maintains REACH Unaffected status and EAR99 ECCN classification, identical to the original part. It is RoHS3 compliant, supporting current environmental regulations.

Q: Why are both parts classified as obsolete?

A: Both the CPC5604A and CPC5620ATR are end-of-life products from IXYS. Obsolete classification indicates these components are no longer in active production. Existing inventory may be available through authorized distributors for legacy system support and maintenance applications.
