MIC5014BN Equivalent & Substitute Parts

Part Overview

The MIC5014BN is a high-side or low-side gate driver IC manufactured by Microchip Technology, designed for driving N-channel MOSFETs in power management applications. This single-channel, non-inverting gate driver operates across a wide supply voltage range of 2.75V to 30V and is housed in an 8-DIP through-hole package.

The MIC5014BN is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure continued availability for new designs, maintenance applications, and production continuity where this component is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MIC5014BN is determined by strict equivalence across the following critical parameters:

• Driven Configuration: High-Side or Low-Side capability
• Channel Type: Single channel
• Gate Type: N-Channel MOSFET driver
• Voltage - Supply: 2.75V ~ 30V operating range
• Logic Voltage Thresholds: VIL = 0.8V, VIH = 2V
• Input Type: Non-Inverting signal logic
• Operating Temperature Range: -40°C ~ 150°C (TJ)
• Package / Case: 8-DIP (0.300", 7.62mm) through-hole form factor
• Supplier Device Package: 8-PDIP

The MIC5014YN meets all these criteria and is therefore a direct functional equivalent. Both parts share the same base product number (MIC5014) and are manufactured by Microchip Technology, ensuring design and pin compatibility.

Parameter Comparison

Engineering Selection Recommendations

The MIC5014YN is the direct substitute for the obsolete MIC5014BN. Both parts are electrically and mechanically identical across all functional parameters, with identical pin configurations and package dimensions.

Key Advantages of MIC5014YN:

• Product Status: Active production status ensures long-term availability and supply chain reliability
• RoHS Compliance: ROHS3 compliant, meeting current environmental and regulatory requirements
• Inventory Availability: 2,100 units in stock, compared to 3,187 units of the obsolete MIC5014BN

Compliance Considerations:

• Both parts maintain REACH Unaffected status and EAR99 export classification
• Both parts carry HTSUS code 8542.39.0001
• Moisture sensitivity level remains unchanged at MSL 1 (Unlimited)

For new designs and production applications, the MIC5014YN is the recommended selection. For legacy system maintenance where the MIC5014BN is currently specified, direct substitution with the MIC5014YN is functionally equivalent with no circuit modifications required.

Frequently Asked Questions (FAQ)

Q: Can the MIC5014YN be used as a direct replacement for the MIC5014BN?

A: Yes. The MIC5014YN is a direct functional equivalent. All electrical parameters, logic thresholds, supply voltage range, operating temperature range, and pin configurations are identical. The 8-DIP through-hole package dimensions are the same, enabling direct board-level substitution without circuit redesign.

Q: What is the difference between the MIC5014BN and MIC5014YN?

A: The primary differences are product status and regulatory compliance. The MIC5014BN is obsolete, while the MIC5014YN is in active production. The MIC5014YN is ROHS3 compliant, whereas the MIC5014BN is RoHS non-compliant. Functionally and electrically, both parts are identical.

Q: Are there any package or pinout differences?

A: No. Both parts use the 8-DIP (0.300", 7.62mm) through-hole package with identical pinouts. The MIC5014YN is supplied in tube packaging, while the MIC5014BN packaging specification was not provided. This does not affect electrical compatibility or board-level installation.

Q: Why should I choose the MIC5014YN over the MIC5014BN?

A: The MIC5014YN is recommended for all new designs and production applications because it is in active production status, ensuring long-term supply chain availability. It also meets current RoHS3 environmental compliance standards. For legacy systems currently using the MIC5014BN, substitution with the MIC5014YN requires no circuit modifications.

Q: What are the critical parameters for substitution?

A: Substitution is valid when the following parameters match: driven configuration (high-side or low-side), single-channel architecture, N-channel MOSFET gate type, supply voltage range (2.75V ~ 30V), logic voltage thresholds (VIL = 0.8V, VIH = 2V), non-inverting input type, operating temperature range (-40°C ~ 150°C), and 8-DIP through-hole package format.

Q: Is the MIC5014YN suitable for high-temperature applications?

A: Yes. The MIC5014YN operates across the full temperature range of -40°C to 150°C (TJ), making it suitable for industrial and automotive applications requiring extended temperature performance.
