CS9202YDFR8G Equivalent & Substitute Parts

Part Overview

The CS9202YDFR8G is a linear voltage regulator IC manufactured by onsemi, designed to deliver a fixed 3.3V output at 100mA in an 8-SOIC surface mount package. This device is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity. The part operates across an industrial temperature range of -40°C to 125°C and requires no external output capacitor, simplifying circuit implementation.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the CS9202YDFR8G are selected based on the following critical parameters that define functional equivalence:

• Fixed output voltage of 3.3V
• 8-SOIC package footprint compatibility (0.154", 3.90mm Width)
• Surface mount technology
• Linear regulator topology with positive fixed output configuration
• Operating temperature range support of -40°C minimum
• Moisture sensitivity level MSL 1 or better
• REACH and RoHS compliance status

The two identified substitutes meet these core requirements while offering enhanced specifications in output current capacity and dropout voltage performance compared to the original part.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are active products with current manufacturing support, providing design continuity advantages over the obsolete CS9202YDFR8G. The L4931ABD33-TR and MIC5201-3.3YM-TR are fully compliant with ROHS3 and REACH requirements, meeting modern regulatory standards.

The L4931ABD33-TR offers the highest output current capacity at 250mA, providing additional design margin for applications requiring higher load currents. The MIC5201-3.3YM-TR delivers superior dropout voltage performance at 0.4V @ 150mA, beneficial for low-input-voltage applications.

Temperature range consideration: The MIC5201-3.3YM-TR operates to 85°C maximum junction temperature, which is lower than the CS9202YDFR8G and L4931ABD33-TR at 125°C. Applications requiring the full -40°C to 125°C range should prioritize the L4931ABD33-TR.

Frequently Asked Questions (FAQ)

Q: Can the L4931ABD33-TR or MIC5201-3.3YM-TR be used as direct pin-for-pin replacements for the CS9202YDFR8G?

A: Yes. All three devices share identical 8-SOIC package geometry (0.154", 3.90mm Width) and pinout configuration for linear regulators with fixed 3.3V output. PCB layout modifications are not required for substitution.

Q: What is the primary advantage of using L4931ABD33-TR over the original CS9202YDFR8G?

A: The L4931ABD33-TR provides 250mA output current capacity compared to 100mA, maintains the full -40°C to 125°C operating range, and is an active product with ongoing manufacturer support and availability.

Q: When should MIC5201-3.3YM-TR be selected instead of L4931ABD33-TR?

A: The MIC5201-3.3YM-TR is preferred in applications where low dropout voltage is critical, offering 0.4V @ 150mA versus 0.8V @ 250mA for the L4931ABD33-TR. However, applications requiring operation above 85°C junction temperature should use the L4931ABD33-TR.

Q: Are there any compliance or certification differences between the substitutes?

A: Both substitute parts are ROHS3 compliant and REACH unaffected. Both maintain MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's environmental specifications.

Q: What input voltage range should be considered when selecting a substitute?

A: The L4931ABD33-TR supports up to 20V input, while the MIC5201-3.3YM-TR supports up to 26V input. Design circuits accordingly based on your power supply specifications.
