Key Parameters

Substitute Part Grouping Explanation

Substitution of the CS8182YDF8G is determined by strict equivalence across the following critical parameters:

• Output configuration (positive adjustable)
• Output current capability (200mA)
• Maximum input voltage (45V)
• Voltage dropout specification (0.6V @ 200mA)
• Package type (8-SOIC with 3.90mm width)
• Protection feature set (over-temperature, reverse polarity, short circuit)
• Operating temperature range (-40°C ~ 125°C)
• Quiescent current (55 µA)
• PSRR performance (60dB @ 120Hz)

The CS8182YDFR8G meets all these criteria and qualifies as a direct functional equivalent. The primary distinction between these parts is packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The CS8182YDFR8G is the active equivalent for the obsolete CS8182YDF8G. Both parts share identical electrical specifications, performance characteristics, and package dimensions. Selection between these parts should be based on the following factors:

Product Status: The CS8182YDF8G is obsolete. The CS8182YDFR8G is active and currently in production, making it the appropriate choice for new designs and ongoing procurement.

Compliance: The CS8182YDFR8G carries ROHS3 compliance certification, whereas the main part does not specify this status. For applications requiring RoHS compliance, the CS8182YDFR8G is the mandated selection.

Packaging Format: The CS8182YDF8G is supplied in tube packaging, while the CS8182YDFR8G is supplied in tape and reel format. Tape and reel packaging is standard for automated assembly processes and high-volume production. Tube packaging may require manual handling or special equipment.

Inventory Availability: The CS8182YDFR8G has significantly higher inventory availability (3679 pcs) compared to the main part (1003 pcs), supporting supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the CS8182YDFR8G be used as a direct replacement for the CS8182YDF8G?

A: Yes. Both parts are electrically and mechanically identical. The CS8182YDFR8G is the active production equivalent and is suitable for direct substitution in all applications where the CS8182YDF8G was specified.

Q: What is the difference between the two part numbers?

A: The primary differences are product status (obsolete vs. active), packaging format (tube vs. tape & reel), and RoHS compliance certification. The electrical performance and package dimensions are identical.

Q: Are there any PCB layout or assembly considerations when switching from CS8182YDF8G to CS8182YDFR8G?

A: No. Both parts use the same 8-SOIC package with identical pin configuration and dimensions (0.154" width, 3.90mm). PCB layouts and assembly processes require no modification.

Q: What does the packaging format difference mean for procurement?

A: Tube packaging is typically used for lower-volume or manual assembly applications. Tape and reel packaging is standard for automated pick-and-place assembly and high-volume production. The CS8182YDFR8G in tape and reel format is better suited for modern manufacturing environments.

Q: Is the CS8182YDFR8G RoHS compliant?

A: Yes. The CS8182YDFR8G is ROHS3 compliant. If RoHS compliance is a requirement for your application, this part meets that specification.

Q: What is the moisture sensitivity level, and does it affect handling?

A: Both parts have MSL 3 (168 Hours), indicating moderate moisture sensitivity. Standard ESD and moisture control procedures during storage and assembly are required. Parts should be stored in dry conditions and used within the specified time window after opening sealed packaging.
