CPC5611A Equivalent & Substitute Parts

Part Overview

The CPC5611A 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 equivalent substitute parts is essential for ongoing system maintenance and new design implementations requiring DAA functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CPC5611A is determined by the following critical parameters:

• Package Compatibility: 32-SOIC (0.295", 7.50mm Width) — identical physical and electrical footprint required
• Function: Data Access Arrangement (DAA) — functional equivalence mandatory
• Supply Voltage Range: 3V ~ 5.5V — must support the same operating voltage window
• Mounting Type: Surface Mount — PCB assembly method must remain consistent
• Number of Circuits: 1 — single circuit configuration

The CPC5621A qualifies as a direct substitute based on these parameters. Both parts share identical package geometry, DAA functionality, supply voltage range, and surface mount characteristics. The CPC5621A represents an evolution within the LITELINK® family (LITELINK® III versus LITELINK® II) with enhanced operating temperature range and improved supply current efficiency.

Parameter Comparison

Engineering Selection Recommendations

The CPC5621A serves as the direct substitute for CPC5611A applications. Selection between these parts should be based on the following criteria:

CPC5621A Selection Advantages:

• Extended operating temperature range (-40°C ~ 85°C) accommodates wider environmental conditions compared to CPC5611A (0°C ~ 85°C)
• Reduced supply current (9mA versus 10mA) provides marginal power efficiency improvement
• ROHS3 compliance status provides regulatory advantage for new designs
• Higher inventory availability (9839 Pcs) versus CPC5611A (2096 Pcs)

Compatibility Assurance: Both parts maintain identical 32-SOIC package geometry, DAA functional specification, 3V ~ 5.5V supply voltage range, and surface mount characteristics. Electrical and mechanical substitution is direct without circuit modification.

Both parts carry identical REACH Unaffected and EAR99 export classification status, ensuring regulatory consistency.

Frequently Asked Questions (FAQ)

Q: Can CPC5621A directly replace CPC5611A without PCB modification?

A: Yes. Both parts use identical 32-SOIC package geometry and pinout. No PCB layout changes are required. Direct socket substitution is possible.

Q: What is the functional difference between CPC5611A and CPC5621A?

A: Both implement identical Data Access Arrangement (DAA) functionality. The CPC5621A represents a later generation within the LITELINK® family with extended temperature range and marginally improved current consumption.

Q: Are there temperature range limitations when substituting CPC5621A for CPC5611A?

A: No. The CPC5621A operating range (-40°C ~ 85°C) encompasses the CPC5611A range (0°C ~ 85°C). Applications limited to 0°C ~ 85°C operation face no constraints.

Q: Do supply voltage requirements differ between these parts?

A: No. Both parts operate across identical 3V ~ 5.5V supply voltage range. Power supply circuits require no adjustment.

Q: What is the significance of the MSL rating for these components?

A: Both parts carry MSL 3 (168 Hours) classification. This indicates moisture sensitivity requiring controlled storage and handling conditions. Reflow soldering must occur within 168 hours of package opening under specified humidity conditions.

Q: Are both parts subject to the same export regulations?

A: Yes. Both parts carry identical EAR99 ECCN classification and REACH Unaffected status, ensuring equivalent regulatory treatment for export and compliance purposes.

Q: Why is CPC5611A classified as obsolete?

A: CPC5611A is obsolete per manufacturer status. The CPC5621A represents the current generation equivalent within the LITELINK® product family and should be prioritized for new designs and ongoing procurement.
