Key Parameters

Substitute Part Grouping Explanation

Substitution of the MIC2593-2BTQ is determined by strict equivalence across the following critical parameters:

• Manufacturer and Base Product Number: Both parts must originate from Microchip Technology and share the MIC2593 base product number
• Channel Configuration: 10-channel architecture must be maintained
• Package Specification: 48-TQFP (7x7) surface mount package is mandatory for PCB compatibility
• Electrical Specifications: Supply voltage range (3.3V, 5V, ±12V), output current ratings (100mA, 500mA), and operating temperature range (0°C ~ 70°C) must be identical
• Functional Features: Latched Fault, SMBus, Thermal Limit, UVLO, and programmable features (Current Limit, Fault Timeout, Slew Rate) must be present
• Application Scope: PCI and PCI-X compatibility must be maintained

The MIC2593-2YTQ meets all these criteria and is classified as a direct equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The MIC2593-2YTQ is a direct functional equivalent to the MIC2593-2BTQ. Key differentiation factors are:

Product Status: The MIC2593-2BTQ is obsolete, while the MIC2593-2YTQ is active. For new designs and ongoing production, the MIC2593-2YTQ is the appropriate selection due to continued manufacturer support and availability.

Regulatory Compliance: The MIC2593-2YTQ achieves ROHS3 compliance, whereas the MIC2593-2BTQ is RoHS non-compliant. Systems subject to RoHS regulations must use the MIC2593-2YTQ.

Packaging: The MIC2593-2YTQ is supplied in Tray packaging, while the MIC2593-2BTQ packaging specification is not detailed. Both devices share identical electrical and functional specifications, ensuring direct substitution at the component level.

Electrical and Functional Equivalence: All electrical parameters, channel configuration, feature sets, and programmable capabilities are identical between the two parts, confirming full functional interchangeability.

Frequently Asked Questions (FAQ)

Q: Can the MIC2593-2YTQ directly replace the MIC2593-2BTQ in existing designs?

A: Yes. The MIC2593-2YTQ is electrically and functionally identical to the MIC2593-2BTQ. Both devices feature 10 channels, identical supply voltage ranges (3.3V, 5V, ±12V), matching output current specifications (100mA, 500mA), and the same 48-TQFP (7x7) package. No design modifications are required.

Q: What is the primary reason to transition from MIC2593-2BTQ to MIC2593-2YTQ?

A: The MIC2593-2BTQ is classified as obsolete, making long-term availability uncertain. The MIC2593-2YTQ is an active product with ongoing manufacturer support. Additionally, the MIC2593-2YTQ meets ROHS3 compliance requirements, whereas the MIC2593-2BTQ does not.

Q: Are there any package or pinout differences between these parts?

A: No. Both the MIC2593-2BTQ and MIC2593-2YTQ use the 48-TQFP (7x7) surface mount package with identical pinouts. PCB layouts and footprints are fully compatible.

Q: What are the critical parameters that define substitution eligibility for this product category?

A: For hot plug controller substitution, the following parameters must match: manufacturer (Microchip Technology), base product number (MIC2593), channel count (10), package type (48-TQFP 7x7), supply voltage range (3.3V, 5V, ±12V), output current ratings (100mA, 500mA), operating temperature range (0°C ~ 70°C), and feature set (Latched Fault, SMBus, Thermal Limit, UVLO with programmable Current Limit, Fault Timeout, and Slew Rate).

Q: Does the MIC2593-2YTQ support the same PCI and PCI-X applications as the MIC2593-2BTQ?

A: Yes. Both devices are specified for PCI and PCI-X applications with identical functional capabilities for hot-plug control, power distribution, and fault management.

Q: What is the moisture sensitivity level for both parts?

A: Both the MIC2593-2BTQ and MIC2593-2YTQ have a Moisture Sensitivity Level (MSL) of 3, with a floor life of 168 hours. Identical handling and storage protocols apply to both devices.
