MIC2954-08BM Equivalent & Substitute Parts

Part Overview

The MIC2954-08BM is a linear voltage regulator IC from Microchip Technology designed for positive adjustable (fixed) output applications. This Surface Mount device delivers 250mA output current in an 8-SOIC package and is suitable for power management applications requiring regulated voltage outputs between 1.24V and 29V with input voltages up to 30V. The MIC2954-08BM is currently discontinued at DiGi Electronics, making identification of equivalent substitute parts essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MIC2954-08BM are identified based on strict electrical and mechanical parameter equivalence within the MIC2954 product family. The substitution logic is based on the following key parameters that must remain constant:

• Output Configuration: Positive
• Output Type: Adjustable (Fixed)
• Number of Regulators: 1
• Voltage - Input (Max): 30V
• Voltage - Output (Min/Fixed): 1.24V (5V)
• Voltage - Output (Max): 29V
• Voltage Dropout (Max): 0.6V @ 250mA
• Current - Output: 250mA
• Current - Quiescent (Iq): 300 µA
• Current - Supply (Max): 12 mA
• Control Features: Enable
• Protection Features: Load Dump, Over Current, Over Temperature, Reverse Polarity, UV POR
• Operating Temperature: -40°C ~ 125°C
• Mounting Type: Surface Mount
• Package / Case: 8-SOIC (0.154", 3.90mm Width)

The identified substitutes differ only in packaging format (Tube vs. Bulk) and product status (Active vs. Discontinued), with all electrical and mechanical specifications remaining identical.

Parameter Comparison

Engineering Selection Recommendations

Both MIC2954-08YM and MIC2954-07YM are direct electrical and mechanical equivalents to the MIC2954-08BM, with all functional parameters identical. The primary distinctions are product status and regulatory compliance.

MIC2954-08YM is the preferred direct substitute, maintaining the same part number suffix (-08) while offering Active product status and ROHS3 compliance. This part is currently in stock with 10,100 units available.

MIC2954-07YM is a parametric equivalent with Active product status and ROHS3 compliance. The difference in part number suffix (-07 vs. -08) reflects a packaging or manufacturing variant within the MIC2954 family, but all electrical and mechanical specifications remain identical. This part is currently in stock with 3,161 units available.

For new designs or production requiring regulatory compliance, either MIC2954-08YM or MIC2954-07YM is suitable. The MIC2954-08BM, being discontinued and RoHS non-compliant, should be replaced with one of the active alternatives for ongoing support and compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can MIC2954-08YM be used as a direct replacement for MIC2954-08BM?

A: Yes. MIC2954-08YM is a direct substitute with identical electrical and mechanical specifications. The primary difference is product status (Active vs. Discontinued) and RoHS compliance (ROHS3 vs. non-compliant). All functional parameters, output ratings, protection features, and package dimensions are equivalent.

Q: What is the difference between MIC2954-08YM and MIC2954-07YM?

A: Both parts are parametric equivalents with identical electrical specifications and 8-SOIC packaging. The difference in part number suffix (-08 vs. -07) indicates a variant within the MIC2954 product family, but all voltage ratings, current ratings, protection features, and operating characteristics remain the same. Selection between these two can be based on availability and packaging preference.

Q: Are there any compatibility concerns when substituting MIC2954-08BM with MIC2954-08YM or MIC2954-07YM?

A: No compatibility concerns exist. All three parts share identical electrical specifications, output configurations, protection features, and 8-SOIC package dimensions. PCB layout and circuit design remain unchanged. The only consideration is RoHS compliance status if regulatory requirements apply to your application.

Q: What packaging formats are available for these substitutes?

A: MIC2954-08BM was supplied in Bulk packaging. Both substitute parts (MIC2954-08YM and MIC2954-07YM) are supplied in Tube packaging. This difference affects handling and storage but does not impact electrical performance or PCB integration.

Q: Which substitute part should I select for a new design?

A: MIC2954-08YM is recommended as the primary choice for new designs, as it maintains the same part number suffix and offers Active product status with ROHS3 compliance. MIC2954-07YM is an acceptable alternative if availability or cost considerations favor this variant.
