MIC5158BN Equivalent & Substitute Parts

Part Overview

The MIC5158BN is a Linear Regulator Controller IC manufactured by Microchip Technology, designed for positive fixed or adjustable output applications. This 14-DIP through-hole component operates across a wide input voltage range of 3V to 36V with a supply current of 4.5mA and supports single output regulation. The MIC5158BN is classified as obsolete, making identification of compatible substitute parts essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MIC5158BN is determined by strict equivalence across the following electrical and mechanical parameters:

• Regulator type: Positive Fixed or Adjustable
• Number of outputs: 1
• Input voltage range: 3V ~ 36V
• Supply current: 4.5mA
• Operating temperature range: -40°C ~ 85°C
• Mounting type: Through Hole
• Package configuration: 14-DIP (0.300", 7.62mm)
• Base product number: MIC5158

The MIC5158YN meets all substitution criteria as a direct equivalent from the same manufacturer, maintaining identical electrical specifications and package footprint while offering improved product status and compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The MIC5158YN is a direct functional equivalent to the obsolete MIC5158BN. Both components share identical electrical specifications, pin configuration, and 14-DIP package footprint, enabling direct substitution without circuit redesign.

The MIC5158YN offers two significant advantages over the MIC5158BN:

• Active product status ensures ongoing manufacturer support and availability
• ROHS3 compliance satisfies modern regulatory requirements, whereas the MIC5158BN is RoHS non-compliant

Both components maintain equivalent REACH status and moisture sensitivity characteristics. Selection between these parts should be based on regulatory compliance requirements and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can the MIC5158YN replace the MIC5158BN in existing designs?

A: Yes. The MIC5158YN is a direct substitute with identical electrical specifications, pin configuration, and 14-DIP package dimensions. No circuit modifications are required.

Q: What is the primary difference between these two parts?

A: The MIC5158BN is obsolete with RoHS non-compliant status, while the MIC5158YN is an active product with ROHS3 compliance. Electrical performance and package footprint are identical.

Q: Are there any package or mounting differences?

A: No. Both components use the same 14-DIP (0.300", 7.62mm) through-hole package and are mounted identically on PCBs.

Q: Does the MIC5158YN have the same input voltage and temperature operating range?

A: Yes. Both parts operate across 3V to 36V input voltage and -40°C to 85°C temperature range with identical 4.5mA supply current.

Q: What is the significance of ROHS3 compliance on the MIC5158YN?

A: ROHS3 compliance indicates the MIC5158YN meets current European Union Restriction of Hazardous Substances regulations, making it suitable for applications with regulatory compliance requirements. The MIC5158BN does not meet this standard.
