Key Parameters

Substitute Part Grouping Explanation

Substitution of the CPC5620ATR is determined by strict equivalence across the following critical parameters:

• Function: Data Access Arrangement (DAA) telecom interface
• Package: 32-SOIC (0.295", 7.50mm Width) surface mount
• Electrical Specifications: Supply voltage 3V ~ 5.5V, supply current 9mA, power consumption 1 W
• Operating Temperature Range: -40°C ~ 85°C
• Compliance: ROHS3 compliant, REACH unaffected
• Moisture Sensitivity: MSL 3 (168 Hours)

The CPC5621ATR meets all these criteria and is classified as a parametric equivalent within the LITELINK® III series.

Parameter Comparison

Engineering Selection Recommendations

The CPC5621ATR is a direct parametric equivalent to the CPC5620ATR. Both components share identical electrical specifications, package geometry, operating temperature range, and compliance certifications. The primary difference is the manufacturer: IXYS Integrated Circuits Division for the CPC5620ATR and Littelfuse for the CPC5621ATR.

Selection between these parts should be based on availability, supply chain considerations, and procurement lead times. Both components are classified as obsolete, which may impact long-term availability. Inventory verification is recommended prior to design commitment.

Frequently Asked Questions (FAQ)

Q: Can the CPC5621ATR be used as a direct replacement for the CPC5620ATR?

A: Yes. The CPC5621ATR is a parametric equivalent with identical electrical specifications, package dimensions, operating temperature range, and compliance status. Pin-for-pin compatibility is maintained within the 32-SOIC package.

Q: Are there any differences in package handling or storage requirements?

A: Both components share identical Moisture Sensitivity Level (MSL) ratings of 3 (168 Hours). Storage and handling procedures are equivalent.

Q: What is the significance of the obsolete product status?

A: Obsolete status indicates that both the CPC5620ATR and CPC5621ATR are no longer in active production. Availability is limited to existing inventory. Procurement planning should account for potential supply constraints.

Q: Are both parts RoHS compliant?

A: Yes. Both the CPC5620ATR and CPC5621ATR are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided that the design does not include manufacturer-specific requirements or qualifications. The identical electrical and mechanical parameters support direct substitution.
