MIC39102BM Linear Voltage Regulator Equivalent & Substitute Parts

Part Overview

The MIC39102BM is a linear voltage regulator IC from Microchip Technology designed for positive adjustable output applications. It delivers 1A output current with an adjustable voltage range from 1.24V to 16V, suitable for power management applications requiring precision voltage regulation. The MIC39102BM is currently discontinued at DiGi Electronics, making identification of compatible substitute parts essential for ongoing design support and procurement.

• Voltage - Input (Max): 16V
• Voltage - Output (Min/Fixed): 1.24V
• Voltage - Output (Max): 16V
• Voltage Dropout (Max): 0.63V @ 1A
• Current - Output: 1A
• Control Features: Enable
• Protection Features: Over Current, Over Temperature, Reverse Polarity
• Operating Temperature: -40°C ~ 125°C
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Base Product Number: MIC39102

The MIC39102YM shares identical electrical specifications and mechanical packaging with the MIC39102BM, differing only in packaging format (Tube vs. unspecified) and compliance certifications. Both parts are manufactured by Microchip Technology and belong to the same MIC39102 base product family.

Parameter Comparison

Engineering Selection Recommendations

The MIC39102YM is a direct functional equivalent to the MIC39102BM. Both parts deliver identical electrical performance and mechanical compatibility within the 8-SOIC package footprint. The MIC39102YM maintains active product status with higher inventory availability, whereas the MIC39102BM is discontinued.

The MIC39102YM achieves ROHS3 compliance, whereas the MIC39102BM is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the MIC39102YM is the appropriate selection. Both parts maintain REACH Unaffected status and EAR99 export classification.

Moisture sensitivity differs between the two parts: MIC39102BM carries MSL 1 (Unlimited), while MIC39102YM carries MSL 2 (1 Year). This distinction affects storage and handling protocols but does not impact electrical or mechanical substitution compatibility.

Frequently Asked Questions (FAQ)

Q: Can the MIC39102YM directly replace the MIC39102BM in existing designs?

A: Yes. Both parts share identical electrical specifications, output characteristics, and 8-SOIC package dimensions. Pin-for-pin compatibility is maintained across all functional parameters.

Q: What is the difference between the MIC39102BM and MIC39102YM?

A: The parts are electrically and mechanically identical. Differences exist in product status (discontinued vs. active), RoHS compliance (non-compliant vs. ROHS3 compliant), moisture sensitivity level (MSL 1 vs. MSL 2), and packaging format (unspecified vs. Tube). Inventory availability also differs significantly.

Q: Are there any compatibility concerns when substituting MIC39102YM for MIC39102BM?

A: No compatibility concerns exist for electrical or mechanical substitution. The MIC39102YM operates within the same voltage ranges, current ratings, temperature specifications, and protection features. PCB layout and schematic integration remain unchanged.

Q: Does the RoHS compliance difference affect substitution?

A: RoHS compliance status does not affect electrical or mechanical substitution. However, regulatory requirements for your application may mandate selection of the ROHS3-compliant MIC39102YM. Verify compliance requirements for your specific end-use application.

Q: What does MSL 2 (1 Year) mean for the MIC39102YM?

A: Moisture Sensitivity Level 2 with a 1-year floor life indicates the component must be stored in controlled humidity conditions and used within one year of the manufacturing date. This affects storage, handling, and shelf-life management but does not impact electrical performance or substitution compatibility.

Q: Is the MIC39102BM still available for procurement?

A: The MIC39102BM is discontinued at DiGi Electronics. The MIC39102YM is the active equivalent with higher inventory availability. For new designs or ongoing procurement, the MIC39102YM is the recommended selection.
