Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MIC2566-0YTS-TR is determined by the following critical parameters:

• Switch Type & Output Configuration: Must maintain PCMCIA switch functionality with low-side N-channel output
• Interface & Control: Non-inverting logic interface with status flag capability
• Fault Protection: Current limiting (fixed) and over-temperature protection required
• Operating Temperature Range: -40°C ~ 85°C (TA) compatibility
• Compliance & Certifications: ROHS3 compliance and REACH unaffected status

The MIC2562A-0YM-TR qualifies as a manufacturer-recommended substitute. While it introduces differences in input-to-output ratio (3:2 vs. 1:1), maximum output current (200mA vs. 120mA), and on-resistance characteristics (70mOhm vs. 1.4Ohm), it maintains functional equivalence in switch type, output configuration, interface logic, fault protection mechanisms, and compliance requirements. The enhanced current capability and improved on-resistance provide performance headroom for applications previously constrained by the MIC2566-0YTS-TR specifications.

Parameter Comparison

Engineering Selection Recommendations

The MIC2562A-0YM-TR is designated as the manufacturer-recommended substitute for the obsolete MIC2566-0YTS-TR. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new designs and production transitions.

The MIC2562A-0YM-TR offers active product status with significantly higher inventory availability (3436 Pcs vs. 857 Pcs), supporting long-term supply chain stability. The component's enhanced electrical characteristics—increased maximum output current (200mA) and reduced on-resistance (70mOhm)—provide performance margin for existing applications while enabling expanded design flexibility.

Package transition from 14-TSSOP to 14-SOIC requires PCB layout modification. Both packages maintain surface-mount compatibility and identical pin counts, facilitating schematic and functional equivalence with localized board-level changes.

Frequently Asked Questions (FAQ)

Q: Can the MIC2562A-0YM-TR directly replace the MIC2566-0YTS-TR without circuit modifications?

A: Functional substitution is supported at the schematic level due to matching switch type, output configuration, interface logic, and fault protection mechanisms. Package transition from 14-TSSOP to 14-SOIC requires PCB layout modification. Electrical parameter differences (current rating, on-resistance, input-to-output ratio) must be evaluated against application load requirements.

Q: What are the key electrical differences between these components?

A: The MIC2562A-0YM-TR provides 200mA maximum output current versus 120mA for the MIC2566-0YTS-TR, with significantly lower on-resistance (70mOhm vs. 1.4Ohm). The input-to-output ratio differs (3:2 vs. 1:1). Load voltage support expands to include 12V in addition to 3.3V and 5V. These enhancements represent performance improvements suitable for applications previously limited by MIC2566-0YTS-TR specifications.

Q: Are there compliance or certification differences?

A: Both components maintain ROHS3 compliance and REACH unaffected status. Moisture sensitivity level differs (MSL 1 vs. MSL 3), affecting storage and handling requirements. The MIC2562A-0YM-TR requires 168-hour moisture protection protocols compared to unlimited storage for the MIC2566-0YTS-TR.

Q: What is the impact of package change from 14-TSSOP to 14-SOIC?

A: Package dimensions differ (0.173" vs. 0.154" width), requiring PCB footprint redesign. Pin count remains identical at 14 pins, maintaining functional pin compatibility. Surface-mount assembly processes remain compatible with standard reflow equipment.

Q: Why is the MIC2562A-0YM-TR recommended over other potential alternatives?

A: The MIC2562A-0YM-TR is designated as the manufacturer-recommended substitute by Microchip Technology, ensuring design validation and long-term support. Active product status guarantees ongoing availability and supply chain continuity compared to obsolete alternatives.
