MIC5842BN Equivalent & Substitute Parts

Part Overview

The MIC5842BN is a Power Switch/Driver integrated circuit manufactured by Microchip Technology, designed for 1:8 bipolar output switching applications with a maximum output current of 500mA. This component operates as a latched driver with low-side output configuration and serial/strobe interface control. The MIC5842BN is classified as obsolete, making identification of active equivalent parts essential for new designs and ongoing production support.

Substitute Part Grouping Explanation

The MIC5842YN qualifies as a direct substitute for the MIC5842BN based on identical electrical and mechanical specifications. Substitution is valid when the following parameters match:

• Switch Type: Latched Driver (identical)
• Number of Outputs: 8 (identical)
• Ratio - Input:Output: 1:8 (identical)
• Output Configuration: Low Side (identical)
• Output Type: Bipolar (identical)
• Interface: Strobe, Serial (identical)
• Voltage - Load (Max): 15V (identical)
• Current - Output (Max): 500mA (identical)
• Input Type: Non-Inverting (identical)
• Operating Temperature: -55°C ~ 85°C (TA) (identical)
• Package / Case: 18-DIP (0.300", 7.62mm) (identical)
• Mounting Type: Through Hole (identical)

The MIC5842YN maintains full functional and pin compatibility with the MIC5842BN, differing only in product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The MIC5842YN is the direct functional equivalent of the MIC5842BN for all electrical and mechanical applications. Selection between these parts should be based on the following criteria:

For New Designs and Production: The MIC5842YN is the appropriate choice. It maintains active product status with Microchip Technology and carries ROHS3 compliance certification, meeting current regulatory requirements for electronic component manufacturing and distribution.

For Legacy System Support: The MIC5842BN remains available in inventory (1224 pcs) for applications requiring the original part number. However, the MIC5842YN provides identical functionality with improved compliance status.

Compliance Considerations: The MIC5842YN's ROHS3 compliance and active product status provide assurance of continued manufacturing support and supply chain availability. Both parts carry REACH Unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can the MIC5842YN directly replace the MIC5842BN in existing designs?

A: Yes. The MIC5842YN is a direct pin-for-pin and functional equivalent. All electrical parameters, output characteristics, interface specifications, and package dimensions are identical. No circuit modifications are required.

Q: What is the difference between MIC5842BN and MIC5842YN?

A: The primary differences are product status and compliance certifications. The MIC5842BN is obsolete and RoHS non-compliant, while the MIC5842YN is active and ROHS3 compliant. Electrical and mechanical specifications are identical.

Q: Are there any package or mounting differences?

A: Both parts use the 18-DIP (0.300", 7.62mm) package with through-hole mounting. The MIC5842YN is supplied in tube packaging, while the MIC5842BN packaging is not specified.

Q: Which part should be selected for new production?

A: The MIC5842YN should be selected for new designs and ongoing production. It provides active product status, regulatory compliance, and equivalent performance to the obsolete MIC5842BN.

Q: Is the MIC5842YN suitable for applications requiring RoHS compliance?

A: Yes. The MIC5842YN carries ROHS3 compliance certification, making it suitable for applications and markets requiring RoHS-compliant components.
