MIC2587R-2BM Equivalent & Substitute Parts
Part Overview
The MIC2587R-2BM is a Hot Swap Controller manufactured by Microchip Technology, designed for general-purpose applications requiring single-channel hot swap control. This component operates across a wide supply voltage range of 10V to 80V and integrates programmable features including current limit, fault timeout, slew rate, and under-voltage lockout (UVLO). The MIC2587R-2BM is currently discontinued at DiGi Electronics, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Substitute Part Grouping Explanation
Substitution of the MIC2587R-2BM is determined by strict equivalence across the following critical parameters:
- Identical manufacturer (Microchip Technology)
- Identical base product number (MIC2587)
- Identical package type (8-SOIC)
- Identical electrical specifications (voltage range, current supply, operating temperature)
- Identical functional features (single channel, auto retry, programmable current limit, fault timeout, slew rate, UVLO)
- Identical mounting type (Surface Mount)
The MIC2587R-2YM meets all substitution criteria. The primary difference between these parts is packaging format (Bulk versus Tube) and product status (Discontinued versus Active).

Engineering Selection Recommendations
The MIC2587R-2YM is the direct functional equivalent of the MIC2587R-2BM. All electrical and functional specifications are identical, ensuring pin-for-pin and functional compatibility in existing designs.
Selection between these parts should be based on the following factors:
- Product Status: The MIC2587R-2YM is Active, while the MIC2587R-2BM is Discontinued. For new designs and ongoing production, the MIC2587R-2YM is the appropriate choice.
- Compliance Requirements: The MIC2587R-2YM is ROHS3 Compliant, whereas the MIC2587R-2BM is RoHS non-compliant. Applications subject to RoHS regulations must use the MIC2587R-2YM.
- Moisture Sensitivity: The MIC2587R-2YM has MSL 3 (168 Hours), compared to MSL 1 (Unlimited) for the MIC2587R-2BM. Storage and handling procedures must account for this difference.
- Packaging Format: The MIC2587R-2YM is supplied in Tube format, while the MIC2587R-2BM was supplied in Bulk format. Packaging selection depends on procurement and assembly requirements.
Frequently Asked Questions (FAQ)
Q: Can the MIC2587R-2YM directly replace the MIC2587R-2BM in existing designs?
A: Yes. The MIC2587R-2YM is functionally and electrically identical to the MIC2587R-2BM. All electrical parameters, pin configurations, and functional features are equivalent. No design modifications are required.
Q: What is the primary reason to transition from MIC2587R-2BM to MIC2587R-2YM?
A: The MIC2587R-2BM is discontinued at DiGi Electronics. The MIC2587R-2YM is the active equivalent part from the same manufacturer and base product line, ensuring continued availability and support.
Q: Are there compliance differences between these parts?
A: Yes. The MIC2587R-2YM is ROHS3 Compliant, while the MIC2587R-2BM is RoHS non-compliant. Applications subject to RoHS directives must use the MIC2587R-2YM.
Q: Does the difference in Moisture Sensitivity Level (MSL) affect compatibility?
A: No, it does not affect electrical or functional compatibility. However, the MIC2587R-2YM (MSL 3, 168 Hours) requires more stringent moisture control during storage and handling compared to the MIC2587R-2BM (MSL 1, Unlimited). Proper storage conditions and handling procedures must be observed.
Q: Is the packaging format difference significant?
A: The packaging format difference (Bulk versus Tube) does not affect component functionality or electrical performance. Selection depends on procurement volume, assembly line requirements, and inventory management practices.
Q: Are both parts from the same manufacturer?
A: Yes. Both the MIC2587R-2BM and MIC2587R-2YM are manufactured by Microchip Technology and share the same base product number (MIC2587).
