Key Parameters

Substitute Part Grouping Explanation

Substitution of the CS8182YDFR8 is determined by strict equivalence across the following critical parameters:

• Manufacturer base product number (CS8182)
• Output configuration (Positive)
• Output type (Adjustable)
• Number of regulators (1)
• Voltage specifications (Input Max: 45V, Output tracking, Dropout: 0.6V @ 200mA)
• Current ratings (Output: 200mA, Quiescent: 55 µA, Supply Max: 25 mA)
• Signal characteristics (PSRR: 60dB @ 120Hz)
• Protection features (Over Temperature, Reverse Polarity, Short Circuit)
• Operating temperature range (-40°C ~ 125°C)
• Package type (8-SOIC)

The CS8182YDFR8G qualifies as a direct substitute based on identical electrical and mechanical specifications. The primary distinction is packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The CS8182YDFR8G is the active equivalent for the obsolete CS8182YDFR8. Both parts share identical electrical performance and mechanical compatibility. The CS8182YDFR8G is currently in active production status with higher inventory availability (3679 pcs vs. 1027 pcs).

The CS8182YDFR8G carries ROHS3 compliance, whereas the original CS8182YDFR8 is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulatory requirements. Both parts maintain identical REACH status and moisture sensitivity specifications.

Packaging format differs between the two parts: the main part is supplied in bulk format, while the substitute is supplied in Tape & Reel (TR) format. This packaging difference does not affect electrical or mechanical compatibility but may influence procurement and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can CS8182YDFR8G be used as a direct replacement for CS8182YDFR8?

A: Yes. Both parts are manufactured by onsemi under the same base product number (CS8182) and share identical electrical specifications, output characteristics, protection features, and 8-SOIC package dimensions. The substitute is electrically and mechanically interchangeable.

Q: What is the primary difference between these two parts?

A: The main differences are product status and compliance certification. The CS8182YDFR8G is in active production with ROHS3 compliance, while the CS8182YDFR8 is obsolete and RoHS non-compliant. Packaging format also differs: bulk versus Tape & Reel.

Q: Does the Tape & Reel packaging affect circuit board assembly?

A: No. Tape & Reel packaging is a standard format for automated pick-and-place assembly equipment. The physical component dimensions and pin configuration remain identical to bulk-packaged versions.

Q: Are there any electrical performance differences between the two parts?

A: No. Both parts deliver identical electrical performance: 200mA output current, 0.6V maximum dropout voltage, 60dB PSRR at 120Hz, 55 µA quiescent current, and the same protection feature set.

Q: Which part should be selected for new designs?

A: The CS8182YDFR8G should be selected for new designs. It is in active production status, carries ROHS3 compliance, and has higher inventory availability.

Q: Are moisture sensitivity specifications identical?

A: Yes. Both parts carry MSL 3 rating with 168-hour exposure limits.
