MIC5253-1.85BC5 Equivalent & Substitute Parts

Part Overview

The MIC5253-1.85BC5 is a linear voltage regulator IC from Microchip Technology's Teeny™ series, designed to deliver a fixed 1.85V output at up to 100mA. This positive fixed regulator operates across an input range up to 5.5V with a maximum dropout voltage of 0.3V at full load, making it suitable for low-power applications requiring stable voltage regulation in compact form factors.

The MIC5253-1.85BC5 carries an Obsolete product status. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production or maintenance requirements for systems utilizing this regulator.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MIC5253-1.85BC5 is determined by strict equivalence across the following critical parameters:

• Fixed output voltage of 1.85V
• Output current capability of 100mA
• Maximum input voltage of 5.5V
• Dropout voltage specification of 0.3V @ 100mA
• Identical package configuration: SC-70-5 (5-TSSOP, SOT-353)
• Surface mount technology
• Operating temperature range of -40°C to 125°C
• Presence of Over Current, Over Temperature, and UVLO protection

The MIC5253-1.85YC5-TR qualifies as a direct substitute based on complete alignment with all electrical and mechanical parameters. The primary distinction is packaging format (Tape & Reel versus bulk) and product status (Active versus Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The MIC5253-1.85YC5-TR is the direct substitute for the MIC5253-1.85BC5. Both parts are electrically and mechanically identical across all specified parameters.

Selection between these parts should be based on the following factors:

• Product Status: The MIC5253-1.85YC5-TR carries Active status, ensuring ongoing manufacturer support and availability. The MIC5253-1.85BC5 is Obsolete and subject to discontinuation.
• Compliance: The MIC5253-1.85YC5-TR is ROHS3 Compliant, while the MIC5253-1.85BC5 is RoHS non-compliant. Applications requiring RoHS compliance must use the substitute part.
• Packaging: The MIC5253-1.85YC5-TR is supplied in Tape & Reel format, suitable for automated assembly. The MIC5253-1.85BC5 is supplied in bulk packaging.
• Inventory Availability: The MIC5253-1.85YC5-TR has higher inventory availability (1108 Pcs) compared to the MIC5253-1.85BC5 (640 Pcs).

Frequently Asked Questions (FAQ)

Q: Can the MIC5253-1.85YC5-TR be used as a direct replacement for the MIC5253-1.85BC5?

A: Yes. Both parts are electrically and mechanically identical. All electrical specifications, output voltage, current ratings, protection features, and package configurations are equivalent. The primary differences are product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. Bulk).

Q: What is the difference between the packaging formats?

A: The MIC5253-1.85BC5 is supplied in bulk packaging, while the MIC5253-1.85YC5-TR is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated pick-and-place assembly processes. Bulk packaging is typically used for manual assembly or lower-volume applications.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical performance. Both parts deliver identical electrical specifications. However, applications subject to RoHS requirements must use the MIC5253-1.85YC5-TR.

Q: Are there any thermal or reliability differences between these parts?

A: No. Both parts share identical operating temperature ranges (-40°C to 125°C), protection features, and thermal characteristics. Reliability and performance are equivalent.

Q: What should I consider when transitioning from the obsolete part to the substitute?

A: Verify that your assembly process accommodates Tape & Reel packaging if transitioning to the MIC5253-1.85YC5-TR. Confirm that your application meets RoHS compliance requirements. Electrical performance and PCB layout remain unchanged.
