CS9202YDFR8 Equivalent & Substitute Parts

Part Overview

The CS9202YDFR8 is a linear voltage regulator IC manufactured by onsemi, designed to deliver a fixed 3.3V output in an 8-SOIC surface mount package. This device is classified as a Power Management (PMIC) component and is currently marked as obsolete. Due to its discontinued status, identifying functionally equivalent substitute parts is essential for design continuity, production planning, and system maintenance. The CS9202YDFR8 operates without requiring external output capacitors, making it suitable for space-constrained applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CS9202YDFR8 are identified based on the following critical parameters that determine functional equivalence:

• Output Voltage: Fixed 3.3V output
• Package Type: 8-SOIC surface mount package with identical physical dimensions (0.154", 3.90mm Width)
• Functional Category: Linear voltage regulator IC
• Mounting Configuration: Surface mount technology
• Regulatory Compliance: RoHS and REACH status alignment

The MIC5201-3.3YM-TR qualifies as a substitute based on matching output voltage specification, identical package footprint, and compatible functional classification as a linear voltage regulator. Both devices operate in the same package form factor, enabling direct PCB layout compatibility.

Parameter Comparison

Engineering Selection Recommendations

The MIC5201-3.3YM-TR is the identified substitute for the obsolete CS9202YDFR8 based on matching electrical output specification and identical package footprint. Key considerations for selection:

Product Status: The CS9202YDFR8 is obsolete, making the active MIC5201-3.3YM-TR the appropriate choice for new designs and ongoing production requirements.

Compliance Alignment: The MIC5201-3.3YM-TR achieves ROHS3 compliance, whereas the original part is RoHS non-compliant. This distinction is relevant for applications subject to RoHS regulatory requirements.

Package Compatibility: Both devices utilize the 8-SOIC package with identical physical dimensions, enabling direct PCB footprint compatibility without layout modifications.

Availability: The MIC5201-3.3YM-TR maintains active production status with substantial inventory availability, ensuring supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the MIC5201-3.3YM-TR be used as a direct replacement for the CS9202YDFR8?

A: Yes, the MIC5201-3.3YM-TR is functionally equivalent for applications requiring a fixed 3.3V output in an 8-SOIC package. Both devices share identical package dimensions and output voltage specification, enabling direct PCB substitution.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer origin (onsemi vs. Microchip Technology), product status (obsolete vs. active), and RoHS compliance (non-compliant vs. ROHS3 compliant). The MIC5201-3.3YM-TR provides additional documented specifications including output current rating (150mA), dropout voltage, and integrated protection features.

Q: Are there any package or pinout considerations when substituting?

A: Both parts use the 8-SOIC package with identical physical dimensions (0.154", 3.90mm Width). Pinout compatibility must be verified against the specific application schematic, as linear regulators in this package class typically follow standard pin assignments but should not be assumed without datasheet confirmation.

Q: What is the significance of the RoHS compliance difference?

A: The CS9202YDFR8 is RoHS non-compliant, while the MIC5201-3.3YM-TR is ROHS3 compliant. For applications subject to RoHS regulations or customer requirements, the MIC5201-3.3YM-TR is the appropriate selection.

Q: Why is the CS9202YDFR8 marked as obsolete?

A: Obsolete status indicates the part is no longer manufactured by onsemi. The MIC5201-3.3YM-TR serves as the active alternative for continued design support and production availability.
