Key Parameters

Substitute Part Grouping Explanation

Substitution of the CS5172ED8G is determined by strict equivalence across the following critical parameters:

• Input voltage range: 2.7V to 30V
• Output voltage capability: -2.45V to -40V (Switch)
• Output current: 1.5A (Switch)
• Switching frequency: 280kHz
• Package type: 8-SOIC (0.154", 3.90mm Width)
• Topology support: Buck, Boost, Flyback, Forward Converter, SEPIC
• Output configuration: Positive or Negative Adjustable
• Operating temperature range: -40°C to 125°C (TJ)

The CS5172EDR8G qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. The primary difference is packaging format: the substitute is supplied in Cut Tape (CT) format versus the original's unspecified packaging.

Parameter Comparison

Engineering Selection Recommendations

The CS5172EDR8G is a direct electrical and mechanical equivalent to the CS5172ED8G. Both parts share identical electrical specifications, thermal characteristics, and package geometry. The sole distinction is the tape and reel packaging format of the substitute part.

Both components carry obsolete product status. The CS5172EDR8G provides ROHS3 compliance certification, whereas the original part's RoHS status is not specified in the provided data. Both parts maintain REACH Unaffected status and carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Selection between these parts should be based on procurement availability, packaging requirements for assembly processes, and compliance documentation needs for your application.

Frequently Asked Questions (FAQ)

Q: Can CS5172EDR8G be used as a direct replacement for CS5172ED8G?

A: Yes. Both parts are manufactured by onsemi, share the same base product number (CS5172), and possess identical electrical and thermal specifications. The 8-SOIC package geometry is equivalent, supporting direct PCB-level substitution.

Q: What is the difference between CS5172ED8G and CS5172EDR8G?

A: The primary difference is packaging format. The CS5172EDR8G is supplied in Cut Tape (CT) format, while the original part's packaging format is not specified. All electrical parameters, thermal ratings, and mechanical dimensions are identical.

Q: Are there any compliance differences between these parts?

A: The CS5172EDR8G explicitly carries ROHS3 compliance certification. The original part's RoHS status is not specified in available documentation. Both parts are REACH Unaffected and share identical export classifications.

Q: What topologies does the CS5172ED8G support?

A: This IC supports buck, boost, flyback, forward converter, and SEPIC switching regulator topologies with positive or negative adjustable output configuration.

Q: What is the maximum output current rating?

A: The maximum output current is 1.5A at the switch node across all supported topologies.

Q: Is this part still in production?

A: No. Both the CS5172ED8G and CS5172EDR8G are classified as obsolete products. Procurement should be based on available inventory from authorized distributors.

Q: Can this IC be used in applications requiring synchronous rectification?

A: No. The CS5172ED8G does not include an integrated synchronous rectifier. External rectification components are required for applications where synchronous operation is necessary.
